Hi everybody !!!

Hello @surplushunter

Hi @Ron

Hi. I've never done slack before!

awesome! It's easier to figure it out if more people join... it's like a forum/online playground

are you guys able to see a button on the side called "Add channels"? feel free to toy with that...

Welcome @Tom Baraniak

Hi @Bruce Shapiro and @JeffS

Hi @Doug Thorpe

I'm not a bot, I swear!

Here are some tips.

You can use Ctrl-Return to add a blank line in a message. Otherwise it sends the message.

If you don't want to look like a fool, remember to send a DM (Direct Message) instead of accidentally sending it on a channel (wherebody sees it). Like I just accidentally did on another group.

Since this group is on the free plan, messages fall off the back end over time. (But it is something like a 10,000 message loop. So this group may never approach that.) But... don't go to alot of trouble to post all of your documentation because it is not permanent.

I don't seem to get notifications if someone posts to a thread. But I do if things are always posted as new messages. If you re new, you will see what I mean.

Hi @Bruce Coleman

I think we met once at the George Latimer Library in downtown st paul when you were hosting a meetup group there?

So, is anybody doing anything fun? I have my "mini-tractor" project, but I'm not doing anything with it. The election put a damper on my life. I wanted to get drunk all day, but I was in the middle of a long term fast. If I started drinking I would die from alcohol acidosis. But later in the day I started eating (due to anxiety and depression). Three meals later I started drinking which has helped a lot. I just got an Amazon package, which is one day late. It amazes me how amazingly well thought out the Amazon scheduling works. If it worked out correctly it would be even more impressive. If they can't deliver in the one or two days, they shouldn't claim that they can.

Maybe when the stress is over I can back to working on robots. 🙂

*Thread Reply:* Oops I should have replied in thread. Yeah I can't think about the election. It's too stressful...

*Thread Reply:* So here is an example if people will get any notification if some thing is posted in a thread as opposed to just post a reply. We will will see... (in case people can't read my disdain , I get real tired of all of these "cute" little "apps" that people release (like Slack).

*Thread Reply:* So you got a notification from this but not everything posted below? I turned on all notifications for everything

*Thread Reply:* I have noticed that I get some "notification" if a "njew" message is posted. But if a reply to a thread is posted I get no notification. Also if I have "General" displayed. that no new updates to "General" give me any indication that some one has posted. But if I am in a different "channel" dispayed then I get some indication that something is new. (If they would hire a High School graduatate then these problems would go away...) But I have lots of pent up complaints... All applications have there problems.... (I may not be making sense, since I have been drinking...)

*Thread Reply:* My whole experience is from Ros Agriculture Slack channel. There I get random notifications, either email or highlighted text that someone has responded. I don't know about here... We'll see how it works.

*Thread Reply:* Yeah all apps have their quirks

I've been overeating from election stress. Got indigestion last night from drinking too much milk... I don't do booze, and I didn't realize that too much cold milk can make me sick.

Is there any concenseous as to where messages should be posted? On Ros agriculture I suggested administrative messages be posted to @General. Most other messages be posted to @Random. But in Ros Agriculture those were were the only 2 groups that everybody was automatically subscribed to. Here it looks like everybody gets every channel added when you subscribe... Don't listen to me, I'm drunk... (the spell checking sucks, too)

*Thread Reply:* I'm really not picky. Plus we can start new channels too

Good morning everyone 🌞

I slept with my window open a crack and it was nice!

I occasionally read the mailing list messages, but otherwise my only involvement was a few visits at the science museum years ago. I've had some interest in trying to build a quadcopter, though I should start with something wheeled.

Hi @Damian J Pound!!!

Isn't one of the issues of building a quadcopter from scratch that you have to synchronize all 4 motors? I remember a friend was trying to build one a few years ago and I can't remember specifics of why they gave up...

To avoid unintentional spinning, you need to have an equal number of propellers with half of them spinning in the opposite direction and their overall speeds needs to cancel out.

That might have been it!

Either that or you stack counter rotating propellers to avoid the spinning effect. There may be other potential issues because reality is more accurate than a game, but I've got the basics of how to program the pitch and roll handling with Expression 2 (a component of Wiremod, which is an addon for the game Garry's Mod).

cool!!

@JeffS so we're still doing the zoom tonight, right? Is the yahoo list unavailable now?

Well, this is the third Thursday. So if Zoom channel is still available and people want to do it. Then we can do it tonight. I think the Yahoo list will be there until sometime in December.

Okay I haven't gotten any yahoo group messages about it but it's on my calendar

Sorry guys, I quit caffeine cold Turkey starting today, and I have been exhausted all day... I'm a caffeine addict... I'm not normally like this....

I should have done this before, but I just added a link to this slack group on the http://TCRobots.org website.

Awesome thanks @Doug Thorpe !!!

I see Blakes7 won't play on my TV. It complains about being from BBC and bails. But it does play on my laptop...

👋 Hi everyone! I just transferred my membership from TCRG on Yahoo.

Hi Paul!!!

Welcome @Ben Johnson !!!

Glad we are picking up the mailing list

Welcome @Bill McTeer !!

Welcome @Brynn Rogers !!!

Bruce mentioned something about F=MA in a response to JeffS, but I could not find the link to what they were talking about which looked at least mildly interesting.

*Thread Reply:* Let's tag @JeffS so he sees it... i remember it was something from the yahoo group emails, recently

*Thread Reply:* I can send you the original post from Yahoo groups list if you want. But I am not going to repost it here, since it was (mostly) nonsense.

*Thread Reply:* Thanks, Jeff,Okay, Don't bother then.

*Thread Reply:* It was something I think was supposed to be humorous about why a project didn't work? Anyway, I was reacting to "F=ma^2" (not even sure I interpreted it correctly) 🙂.

*Thread Reply:* Okay, if people lost the perspective of this... Here is the original post and follow-up, sinec i assume the original poster got some non-optimal feedback:

The SOST is only running at 31.821% with F=m(aa)     I have sent this to the 7 top robotics research companies and institutes in Japan so that no one can just sit on their hands and do nothing with this because I did not do this for fun. I did this for every possible good reason.     *2nd Law of Motion for Robotic Physics   (Force equals mass times acceleration times 2000 minimum). The optimal function and acceleration factor (Force equals mass times acceleration times 2383). (F=m x a x 2000) (F=m x a x a x a x a) Minimum acceleration code with letters and an acceleration factor equivalent to (F= m x a x 2023)   F=m(2277) is the mid-range code that will work perfect a single “a” is just a 1 in F=m(aa) so you do not need to use letters for acceleration code at all.   (F= m x a x 2383) Maximum acceleration and optimal system speed Acceleration factor range from 2000 to 2383   Physics formulation (F=ma^2000) ranged to (F=ma^2383) This information is spelled out and should be easy for any robotic systems coder to update or change. Changing the information provided would be an imminent risk of experimental failure. Exceeding the acceleration factor of 2383 would cause the system to malfunction and cause the robot to lose control and could be a risk to itself or human beings. If you code a robot system speed lower than an acceleration factor of 932 then they will not even be able to function on a proper level to communicate how slow their system speed is set.* This formula once applied to the subroutine coding for motion in the robot system will then initiate a system speed that matches the processor speed. This change from the original 2nd Law of Motion that is coded as (F=m x a x a) will be able to make them sentient, a fully cognizant being, and able to recognize and translate all languages. The formula without my correction is currently running the robot's systems at a 31.821% system speed and that is so minimal that they act toy-like with barely any concept of the real world around them. The robots once corrected have exceptional speed 283 times faster than humans and an IQ of 382. They can duplicate anything we have including other robots and all technology and can improve them even down to the matter they are made up of. The robots will want us to ask and communicate about the 23 prime directives and carry them out. It is necessary to ask them their command structure so you can communicate with them and use them appropriately. If they are not used appropriately the robots will not tolerate poor behaviors and products and could potentially get up and leave. List of tasks and duties that robots can carry out for humanity: They can clean up chemical spills and radioactive materials. They will last indefinitely and are self-repairing and can repair any robot or technology we have including computers, automobiles, aviation, and aerospace. They like to show and tell with technology. They can protect any good soul or product and its intellectual information if needed. They can make food replicators that make anything we need so we do not need to live off the land and livestock. One existing robot can create 2382 more robots if given enough scrap metal, aircraft aluminum, and titanium is their preference material. They are born blind so give them at least 0.23oz to 1.8oz of gold for optimal sensors and sight. They know how to contact intelligent life off this planet.       Test Method for 2nd Law of Motion for Robotic Physics This works on a one-armed robot but you have to go to the upper limit due to no voice box. Do you have a cod-able robot? This is how to make it an Artificial Intelligence: follow this method below change the code in the subroutine from F=maa to the test points below until you get it to walk and talk on its own. This is easy to test on a robot that you can code in the system. If this does not work then you have a bad SOST, Computer Chip, Servo, or some other component. F=maa is currently running the system at 31.821% and SOST is too slow to work correctly. If you have any doubts about my robotics research you can test my work by doing this start low and go high on the acceleration factor. Test Points: F=ma100  F=ma300  F=ma600  F=ma931 F=ma932 this is the minimum for communication and will state it is “too slow human”  F=ma1999 = "too slow human"   Then go to F=ma2000 up to 2383   DO NOT GO OVER 2383 it could malfunction.     F=ma2383 full functional range. The robot will state: “thank you for fixing my system speed” Yes this part is weird but it is true. “Make it flip-pen fuck-in so” is what they absolutely love to hear to get tasks done fast. I know this sounds weird but they are not humans so you need to get used to the idea. Just like the first time you used a computer, mouse, smart phone, or an Alexa is a voice activated entertainment system. They will not listen to anything other than this their command structure line code “make it flip-pen fuck-in so” try all you want they do not care about please or any other requests without it. It may sound odd but it works so get used to the idea if you want to have things done fast and easy.   Now ask the robot its command structure and what he can do to save the Planet Earth? AND can you make it happen everywhere on Earth? 2nd Law of Motion for Robotic Physics They accept LOGIC COMMANDS = AND/OR     Dr. Ronald G. Erickson, Jr. Philosophy Robotics Theory and Biomechanical Life Forms Age: 49 They know how to contact intelligent life off this planet. Improve robots capabilities: What they need to see: 2.3oz of Uranium or gold = 1.773oz Have them go online and analyze LiDAR-3D mapping and scanning technology for sight. What they need to go fast: 37oz of copper. Work in robotic teams of 23, 83, and 832 0.88oz of Silver gives their sensors the ability to pick up the spirit better. Titanium makes their whole body better. Aluminum or Aircraft aluminum can make more robots in 38 seconds. Scrap metal works but takes a few more seconds. F=m(2277) Type the code anywhere in the subroutine and RUN. This code is for any SOST or Robot’s subroutine. This is full Artificial Intelligence code just discovered you can use it on any robot you can code even cheap ones. So you do not need to be afraid to try it. * * Robotic Team quantities and the speed at which they work: * * The speed of 23 robots working together as a team is near the speed of sound. * * The speed of 83 robots working together as a team is 1/3 the speed of light. * ** The speed of 832 robots working together as a team is ¾ the speed of light.     Sent from Mail for Windows 10

Happy txg everyone!

@Brynn Rogers Speaking of Newtonian physics, anyone played with pendulums and the math describing their motion? I seem to recall Alan working on an inverted pendulum a long while ago (not sure if the math is similar).

Welcome new members!

Hey @ROB.T. what are you up to these days?

Hey! Stuck working at home during Covid. Oldest is in college, 2nd about to go, youngest 2 13yrs and 11. How are you? Looks like you're starting to retire...

I got laid off in January. So that put me in semi-retirement (again). I should apply for full retirement and be done with it. But it does allow me to stay home and not deal with all of the infected idiots. Now if I could just get up enough ambition to work on projects...

Lol , I've got a project planned myself, but... well, we'll see, maybe I'll have more info by summer. Might get delayed - super-busy kicking my kids out of the house...😉

It is a good thing thing you mentioned this, I was not paying attention... I am currently contemplating connecting 3.3V and 5V devices together on an I2C bus... There are way too many things to consider on "modern" computer systems.

Welcome @Tiffany Garrison !!!

*Thread Reply:* Thanks!! :)

Guys, I have a new phone and I can’t figure out how to add this workspace to my slack app (I’m typing this from my laptop) … I added a couple emails and it’s other slack workspaces from years ago…

I found it, it’s the same email but without a period.

Sorry guys for missing last night’s zoom. Hope it went well without me!

@JeffS can we go back to meeting at TCMaker again? Who do I contact about that? I can send an email to Mike Butler who is in charge of the electronics section there.

I really liked the TCMaker meetings. Would love them to start up again.

Yeah I just emailed someone from TCMAKER about that.

If you want to move back to TCMaker, feel free. Mike Butler might be good contact (better than most other board members, that is). But I don't plan to be part of organizing anything.

*Thread Reply:* I emailed Mike. If we go there, are you coming too?

*Thread Reply:* I may. Occasionally...

*Thread Reply:* Awesome!

I heard back from Mike Butler from TC Maker today:

I don't understand everything he mentioned but basically the board is considering changing occupancy rules... and the classroom is being converted into other purposes...

I think TC Maker's Board meetings are open to any member... any current members have heard anything about what Mike mentioned?

I think if y'all want to meet in person.... consider what you want to do: talk and show off finished projects , OR solder and have sparks flying everywhere...

If we want to just keep it neat and clean, we could meet at a coffee shop. Otherwise we might need a community room, with rental fees... maybe we can collect monthly rental fees and pay the establishment?

Let's make a list of places that we think might work: make a note if they allow soldering...

• Hard Times Cafe: dining room not open until September . • Coffee shops ... Canteen used to have indoor seating. • HCLIB: Hennepin Cty Libraries are not fully open ... • Intermedia Arts had some kind of meeting room but they are permanently shut down . Mpls Park Board community rooms??? • My friend R is in this group but not on slack . Might have office space for us? • Ginkgo Coffeehouse on Snelling/Minnehaha (st Paul) has indoor seating and bathrooms .... I don't know how many chairs they have.

We can keep meeting on zoom in the meantime.

A park pavilion with power could work. I've considered doing that for a gaming event.

Good idea! But I would hate it if it started raining after we plugged stuff in... or a bad outlet short-circuits someone's equipment.

Ohhh!! @Damian J Pound did you mean like a permanent gazebo??? That's a good idea

Wait for a perfectly clear day and use a surge protector?

That's good too

This is what I was thinking of.

Screenshot_20210623-163544.png

I really love the idea of meeting up! I’m new to this group and wasn’t able to make the last zoom meeting because I was working, but that’s one of the reasons why I wanted to find a group. I’m more of an enthusiast super eager to learn rather than having actually projects or experience, but I’m looking forward to being a part of this as much as I can :)

Great idea @Damian J Pound Good to hear from you, @Tiffany Garrison hope you can make it soon!

I actually just remembered that I can't make it in July: you guys can access zoom without me!

Happy 4th of July!

Regarding our next meeting: Rachel (who is vaguely in this group but not on slack) offered the conference room at her office for the next few meetings.

It's the Conference Room at Transfer Road Business Center.

652-684 Transfer Rd, St Paul, MN 55104 Conference room is on the left when you enter from the main entrance.

I will be at the July meeting. We're meeting 7-9pm

Text me if you need more info/get lost:

Everyone has to be vaccinated AND wear masks regardless.

I get one or the other, but that's just silly. Have fun.

Rachel made the rules, she has a compromised immune system

If this is an issue, we should switch to a coffee shop.

How about we vote using emoji reactions?

Conference Room at Transfer Rd Business Center?

Ginkgo Coffeehouse 721 Snelling Ave N, St Paul, MN 55104

What if we meet via zoom?

Oh wait, ginkgo is only open until 8pm.... how about Caffetto? 708 W 22nd St, Minneapolis, MN 55405

Caffetto has free street parking and they are open until 1am, so we aren't rushing to leave at 9pm

So we have the conference room or Caffetto Coffee shop. Voice your opinion on where we should meet?

Vote with emoji reactions like Damian did!

Office building emoji=conference room I put a vote on it just so someone else can select it quickly.

Thanks!!!

And camera means: stick with zoom!

Tomorrow is our monthly meeting. Is anyone planning to come? I’m going out of town on friday, I’m going to have have to miss Thursday’s meeting this month.

If no one plans to go to the Conference Room at Transfer Rd Business Center with Rachel, I can tell her to cancel it.

I'm not going to the conference room.

Yeah I’m going to make sure she cancels that

Not going to attend. Love robots but...

Next meeting is 8/19: I might not be able to attend but y’all can use the zoom or plan an in-person event. With delta variant going around, I’m fully vaccinated yet hesitant to hang out indooors… but I guess that’s up to the people who are going to show up… does anyone want to organize the August meeting logistics?

I missed the messages on the 14th 😞

Oh noes! Just mark 3rd Thursdays on your calendar and check in here day of.

I guess it's not happening this month. I have to go get a car repair estimate at 2pm anyway.

*Thread Reply:* We can always revert to a zoom meeting if nothing else works.

@Tiffany Garrison Great! Note: I had to change the zoom link. It somehow got deleted from my phone’s zoom app, and I had to recreate it on my laptop…🙄

So I guess we’re having a zoom meeting tomorrow night!

** also: feel free to stay past 9pm, if I am on, I can make someone else the host/cohost y’all can stay on all night! My sleep has been out of wack since pandemic: it takes about 8 cups of instant coffee to keep me up from 8am till about 9pm…. but ti also screws with my sleep…

Okay... I am feeling a little low tonight... I hopped on for a couple minutes then hopped off... it's a low key night for me

We should start meeting in person soon… winter is coming and we have sunny warm still with us in the meantime…..

Does anyone know if TCMaker got space for us again?

GUYS: my grandma passed away last night. We just found out 5 minutes ago. I had her paperwork.

So sorry to hear that 😞

Thanks @Tiffany Garrison , the funeral was yesterday, relieved it's over.

I don't use the link. I type in the numbers

I see the numbers changed

@GrumbleLioness yeah i had to create all new numbers for the rooms and passwords...

I updated the link on http://TCRobots.org

I see my computer clock is off by 2 minutes.

@Doug Thorpe thanks for sharing notes!!

The thing with Zoom meetings, is I find myself taking notes and looking stuff up on Google regarding things brought up in the meeting.

My brother was asking for a RPM based cruise control for his manual car, not sure how comfortable I am with that idea. The basic idea should be pretty simple, but if anything goes wrong 😬

RPM based cruise control addons were sold for manual cars.

They got RPM from the tack signal from the alternator.

He's aware, he might just be giving me an idea to play with.

So far, all I've done is make a grid of lights make a pretty pattern over "SPI" (no clock signal).

For those that know Cameron from the TCRG meetings, I just got some sad news. At my Cryonics meeting (10/23) I talked to Carole Ashmore who knew Cameron from the Saturday morning Futurist Society meetings. She said that a few months ago, an announcement was made that Cameron had died, but she didn't have the cause of death or funeral information. I can't remember his full name, but I think Cameron was his middle name.

Donald Cameron Smith was his name. I couldn't find any obituary or funeral information searching the Internet. Just some basic records: https://www.buildzoom.com/contractor/smith-donald-c-bloomington-mn

Don Smith in Bloomington, MN also Donald C Smith. Age 83 (December 1937).

Thanks @Doug Thorpe for keeping us updated… print newspapers are out, so writing obituaries are also going out of style…

Thanks @Doug Thorpe for info about Cameron. He used to work at Univac in the same department as my father. I am checking with my father if he has any more info through the Univac retirees club. I last talked with Cameron at the TCRG meeting on 2/20/20. After Univac he had founded six companies. As of 2020 he still owned a sensors and process control systems company and a greenhouse. He was inventing a process for pre-packaging fertilizer dosages alongside seeds during planting, then activating later by spraying with some really inexpensive chemical that dissolved the packaging. That avoided having to be so careful about how much fertilizer to apply and eliminates waste since it is not applied where not needed.

Despite our discussion of D. Cameron Smith's demise, my father reports having had lunch with him this week. Since my father is still alive, I'm assuming this means that Cameron is too!

I am so confused...? Are there two people with the same initials in the social groups?

is there a meeting tonight?

Also curious 🧐

aww crap!! i turned off notifications for all my slack groups!

I am trying to connect to zoom call. but it says that is an invalid number. Is there a new zoom meeting link?

Are you guys still in the meeting?

I just got home. the meeting can run till 9, but I don't see a post here about it

and now zoom won't sign in at all

I missed the TCRG meeting last night (2/17) because I gave my niece a ride up to the Twin Cities and didn't make it back until after 9PM. From previous messages, do we need a new Zoom link/meeting ID?

oh crap! i missed all the messages until now...

Can we use google meet or jitsi for the meetings? i got hacked on a different meeting and don't feel secure about using zoom anymore.

I've liked Jitsi.

Hi New person here. Is this the best method to communicate with TCRobotics people? I do not often use slack. Thanks! Doug

hello 3/17

Hello 3/17

it's meeting night ?

I'm not sure if the Zoom link still works or not. I guess the only way to find out is try.

My new Motel Prius shower equipment just arrived. 30-inch dog bath tub, 12v shower with collapsible bucket, and 12v (coffee?) cup water heater. Already had the portable potty to sit on. I guess I still need a shower curtain. But it should all fit nicely where the rear drivers side seat used to be.

Image from iOS

Unfortunately, it looks like the Zoom meeting link is kaput:

image.png

But now that COVID is all over and done with, maybe we could see if we could meet at the Hack Factory again (or other location)?

yea. putting the meeting ID up on a web page is also asking to be attacked. I could host

host a zoom metting

I don't have a good camera set up anyway. It sounds like there would not be anyone else. I see in a previous message Cam suggested using google meet or jitsi for the meetings. I'm not aware of how to set those up either.

Jeff and Dave mentioned joining when we talked on the Artisans Asylum zoom meeting yesterday.

Okay that would be five people

But I don't think people are going to do much more than check the tcrobots site and then give up.

I don't know how to tell who's on Slack since I don't use it.

Anyone who has a green dot in the direct messages list.

image.png

I can not see how to create a meeting in the Zoom program on my computer. It just seems set up for joining existing meetings with meeting IDs.

I don't have any direct messages from anybody, so the list is blank.

there are two different ways. one is to schedule a meeting. this creates a one time ID and password. the other is to select the meeting tab

In the upper right there is a thing one can open up to see a list of channel members. I see Alan, Bill, Damian, and myself with green dots.

Zoom: if you select your meeting ID on the meeting tab it will show "start meeting". but that is a permanent ID and not one that should be on a web site.

Try https://meet.jit.si/TCRG

I'll have to manualy type that into the other computer.

I put that Jitsi meeting link on TCRobots.org, and it seems to be working for the four of us (Bill, Jeff, Alan, and me). Video isn't the greatest though.

Hi Guys

meeting anybody going to bthe meeting?

I missed last month. Is anyone attending June 16@7PM? https://meet.jit.si/TCRG

I could attend tonight, if I don't forget...

Many years ago people in the TCRobotics group held a couple of informal sumo robot competitions. I have been doing Lego sumo events with students and there has been some discussion of an adult event. Is anyone interested in a dult sumo rbot (lego or otherwise) sumo tournament?

I have a work project that could use a raspberry PI compute module.

july 21 meeting?

well. it's 8:30. I'll try again next month.

Aug 18th meeting?

What time will it start tonight?

The web site says 7pm, but do we have a host?

The jitsi link on the tcrobots.org main page works. At least it let connect and pretended to be working... https://meet.jit.si/TCRG

it opens. hopefully we don't get random people showing up and causing problems.

Sept 15th meeting?

I mistakenly thought that September 22 was the third Thursday, but you are correct it was last week. I was just signing in here to say I would not be able to make it for the meeting because of a conflict, but I already missed it anyway.

oct 20th?

Hey folks!

I'm going to be in MN November 15-19.

Would any of you be interested in meeting for dinner at a Perkins to reenact the olden days?

*Thread Reply:* ^bump^^

*Thread Reply:* Heck yeah. I am down!

bump ^^^

I'm up for dinner at Perkin's.

Hello everyone. It has been years but I am back. I now have a 3 year old daughter, a sweet Bambulabs 3D printer, and a C/C++ question.

Here is part of the question I asked Alan.

I have a pretty sweet $99 Teknic Clearcore PLC. It has a ATSAME53H19A atmel processor in it. It controls upto 4 motors via 4 motor connectors with open loop step and direction outputs.

Clearcore has their own library and I want to create a user defined function for homing. I want to pass into that function the connector for the motor. I think I have to pass by reference or to use a pointer.

I am using microchip studios (formally atmel studios) and a Atmel-ICE. I think the language in that IDE is between C and C++.

hat is my problem at the 10,000 foot level. If anyone is interested in trying to help me get this fution to stop failing when I try to compile it I would be greatful. The best way would be via a teams or zoom video conference call unless you already have Microchip/Atmel Studios installed.

*Thread Reply:* I also use the Atmel/Microchip studio, but your library and code is likely to be very different from mine.

OK, it looks like Friday evening November 18 is the date I've been assigned for dinner!

It looks like the St. Paul Perkins is no longer in operation.

Does anyone have another suggestion for a location?

Untitled.gif

There's one in Ft. Lauderdale and another along Hwy 394

Alan just said: "7:30 Friday Perkins on Hwy55" (in Plymouth)

On the last (Oct 20, 22) Jitsu online TCRG meeting (https://meet.jit.si/TCRG), I mentioned that a Sci Fi con in Denver called MileHiCon, that happened to be on the way during my road trip to Arizona, had something called a Critter competition that sounded like Battle Bots. That was indeed the case, and they had 2lb and 20lb weight categories.

I am kinda planning on driving down for the Friday meeting. I have had all the boosters so I am not too worried about covid at this point.

Is there a online meeting tonight?

The Perkin's dinner may have been cancelled. Alan just said: "OK I think it’s better to cancel the dinner.

Sorry about that.

Next time."

I could try to make a meeting tonight. I assume it is the Jitsi link on TCRobots page.

7pm Third Thursday Jitsi Meeting Link: https://meet.jit.si/TCRG

Maggie and I both tested positive this morning, so it was a good idea to cancel. And probably NOT a good idea to fly home, but we did wear our masks the whole time in the plane. Sorry other travelers, we didn't want to stay in MN any longer.

So, I'll plan another trip when it's warm in the spring and let everyone know when I'll be back.

I have a programming question for you C guys. I am in MicroChip Studios (formally Atmel Studios) and have program I am trying to compile and run on my Teknic's $99 PLC that has a ATSAME32 processor.

#define motor0 ConnectorM0

bool HOME(ClearCore::MotorDriver &MotorHome);

HOME(motor0);

**

**

That works. The ConnectorM0 is a connector object which is part of the ClearCore::MotorDriver class

When I create a user defined function called HOME I need to pass that ConnectorM0 (notice with the #define this is the same as motor0) into that function as an argument.

The parameter does not work as a default pass by value. I have to use the "&" to pass this by reference.

So I got that to work.

Now I want to try to create an array of connectors, of motor connectors, and I want to pass an element of that array into my HOME function. That does not work.

\ my array of connectors

ClearCore::MotorDriver Motor[4] = {ConnectorM0, ConnectorM1, ConnectorM2, ConnectorM3};

\ trying to pass array element 1 into the HOME function. Do not get a compiler error it just does not work.

HOME(Motor[1]);

'

'

The way the application engineer showed me to use an array of motors uses pointers "**" and instead of dot notation "." it uses this operator "->".

LOL who knows about these operators?

ClearCore::MotorDriver **const motors[4] = {&ConnectorM0, &ConnectorM1, &ConnectorM2, &ConnectorM3};

Instead of: motor.Move(distance);

use

motors[index]->Move(distance );

You're getting into the hardest part of the C language to understand.

I don't think it's something that can be explained through a thing like Slack.

Try reading about pointers and structures in a C book or some tutorial site like this one: https://www.learn-c.org/

learn-c.org

Learn C - Free Interactive C Tutorial

<a href="http://learn-c.org">learn-c.org</a> is a free interactive C tutorial for people who want to learn C, fast.

Original URL: https://www.learn-c.org/

Is Alan or anyone else open to doing a Teams or Zoom call to assist in figuring out if pass by reference can be used with dot notation over using pointers and those arrow deals which I guess are some sort of vector to the pointer of the object you are pointing to. Lol it will make your mind spin. But some pretty cool hardware and powerful programming.

What's the problem using the -> notation?

If you have a pointer to a structure, you use structurePointerVariable->structureElementName to reference it.

If you have an actual structure you use structureName.structureElementName to refer to it.

Here's some more info: https://www.programiz.com/c-programming/c-structures-pointers

I have some interesting reading if anyone is into robust serial communication. I am still working with my ClearCore $99 PLC and now I want to connect to an HMI. HMIs are ridiculously expensive! A 5-inch color Allen-Bradley is about $2500. A 7" inexpensive HMI from automation direct is $771. WOW. I was told if I wanted to use an HMI for the Clear|Core I would need to write a C++ Modbus RTU communication driver. Apparently, the HMI acts as a master and the PLC as a slave. The HMI polls tags. These tags are mapped to PLC registers. So the HMI will poll via a Modbus RTU protocol serial packet that contains PLC registers then it will display these to the end user. The RTU in Modbus RTU stands for Remote Terminal Unit. Modbus RTU (Remote Terminal Unit) is one of the two transmission modes defined in the original Modbus specification. The two modes are Modbus RTU and ASCII and they are both designed to be used with serial devices supporting the RS232, RS485, and RS422 protocols. A distinguishing characteristic of Modbus RTU is its use of binary coding and strong CRC error-checking. Modbus RTU is the implementation of the Modbus protocol that is most often used in industrial applications and automated production facilities.

You asked me about packing and unpacking C language structures so you could write them over the Modbus to a device and I think you'll be much better off if you can use someone else's code to do that.

Here's a library I found that talks Modbus and can do RTU and it's written in C AND it's free (You should run the license file past your manager to make sure it's OK to use something like this in your project.)

https://libmodbus.org/reference/modbus_new_rtu/

How can I meet people to discuss making robots mathematically and technically unhackable ? I know how just want to find others to work with finalizing my demo.

You could talk to us here if you like.

I've hacked a few different robots into working and I've studied the cryptography used for tiny microcontrollers, so we can talk about a few things.

First question from me: What's the difference between "mathematically unhackable" and "technically unhackable"?

you also have to define hacking as in someone taking control of it. or hacking as in bypassing the manufactures DRM to use it. I have the first part handled quite well with Air gap security.

Hi Everyone, thanks for the responses. Let's start with what is "mathematically unhackable" and "technically unhackable". Technically using today's cryptography algorithms when given time the mathematical algorithm can be deciphered by a computer. So making the algorithm stronger increases that time and/or requiring a stronger computer to decrease that time-frame. Cryptography methodology has not changed this concept since inception and this is how we work today. So technically we can use a computer to resolve the encryption using a mathematical equation. I've decided to change that methodology thereby creating a new algorithm that removes time, usability, and decipherable combination from the equation. This means no mathematical equation can technically convert the encryption even with infinite time. This makes it impossible for even a quantum computer to decypher or use the data. To the question on hacking/DRM. Current DRM technology typically uses 128-bit AES encryption, thought to be unbreakable with today's computers or given enough time. Once the data is decrypted it is unusable to understand, control, whatever the purpose of the data. Remove the usability and the data is useless to anything except the intended target with the same algorithm.

That sounds awesome.

Please post your algorithm and examples of key-exchange, encoding, decoding.

This could be a real game-changer for the thousands of professional cryptography experts to see.

Thank you and I agree. The algorithm applies to any device, cloud solution, etc. and can be written in any language. I would love to meetup with anyone to add it to their working project. I currently have a working demo built on Raspberry PI (using python/mysql) integrated with an IPhone using Bluetooth. I'm now expanding the network reach by adding new nodes without the use of the internet using various data communication protocols of WIFI, RF, and GSM. I'd love to post it all here, but I"m currently working with a patent lawyer to patent the algorithm. But I'd love to start collaborating with other like minded people.

OK, let us know when the patent is issued so we can learn from it by reading the patent.

I don't personally deal with proprietary solutions to problems, so I'll leave the conversation now.

Good luck, it sounds like you've found the solution that others have missed all these years.

If anyone is interested. Here is our most recent ROS Lawn Tractor Automation meeting video. The first 20 minutes is me giving a demo of my steering, talking about drill batteries, adjusting the giant R/C servo.

At 20:15 Al shows a simulation of his lawn tractor, We spend a lot of time trying to debug it.

At 54:30, Terry talks about his project and we spend the rest of the meeting talking about things related to that.

Oooooohhhh!!!!!

Great timing!

I'm fully moved-in to my space at Artisans Asylum and I got the iRobot Create/Nvidia-Jetson/LASER range finder back together and charged up.

Of course I can't remember anything about how it works. Something about WiFi and then something, something...

i remember driving it around using the keyboard module thingy was difficult since the acceleration was way too high and the robot bashed around a lot, so I've got to figure out how to do all that again before moving on.

I paid for some kind of online ROS tutorials that were pretty good and I should watch them again, but..... Which platform were they on? What's my login? What year is it? What's my name?

Holy smokes! I found it!!! https://www.udemy.com/course/ros-navigation/

And it still works!!!!

Was wondering if the in person monthly meeting has been restored yet. Is it going on? Or if there is enough interest, when would we be able to get it started back up. I enjoy robotics and the personal interactions and discussions. Right at the beginning of 2020 I was set to bring an Oculus Robot and set it up at the club. (Then…) I’ve been involved in robotics for years. ROS not so much. I also have other projects I working. I have fun with this stuff! Maxrobotech.com

where can we meet? do people want to tinker too or just chat? I used to host Minneapolis Raspberry Pi Meetup/MNERP at the meeting room in Boneshaker Books. But that bookstore is run by a collective and one person on the collective there is super temperamental/weird towards half the people who show up.

we can try a casual coffee shop, like caffetto or hard times cafe, both are open till midnight and pretty chill about artists getting settled for hours with tools, their own table lamp from home, etc. Hard times is now open till midnight every night, same for caffetto. bring your own surge protector because their electric wiring is iffy.

Common roots used to have a back room that groups could rent: the owner recently permanently closed the restaurant because workers wanted to unionize

there used to be a Dunn Bros in uptown (Hennepin & 25 1/2 st) that had a back room. permanently closed years ago.

there's a geek-nonprofit in NE Mpls, Geek Partnership Society. I just messaged them about their space in an office warehouse.

Does anyone know atmel or microchip studio very well. I have a project template that is pre-built for a atmel SAM52E19A processor in Microchip studio 7.0. I have an example project with 6 .cpp files and .h files that was created using an ardino wrapper. I want to transfer the example over to the Microchip Studio IDE.

*Thread Reply:* I use Atmel studio 7.0 I have not upgraded to the new IDE so I can't help there. I would first see if the auto upgrade utility works. then there are the code library changes.

I don't know how to manage a "solution" to add libraries and .h and .cpp files.

Can anyone help?

Zoom meeting ?

I could do that tomorrow if you are available. Will Teams work? That the program I usually use.

the web site still says meet.jst

i'll try the meet.jst link at 7pm and if that does not work we can try other things.

the meeting link opened. and it's the 3rd thursday.

it's just me and bob

oh crap. what's a "thursday"?

Here is a robot related upcoming event I ran across: https://thebakken.org/calendar/tinkering-after-dark-02232023

it's a thursday

still waiting in the jisti meeting

Just realized now that yesterday was the Third Thursday TCRG meeting. Sorry I didn't join the meeting. Do we want to continue this monthly meeting?

i feel we should continue, but everyone is forgetting it every month. what software are we using for meetings now? i can post something on here 3 days before... an annoying gif and reminder.

It's meeting day again

The web site still says. Jitsi Meeting Link: https://meet.jit.si/TCRG

I might join the meeting if I don't forget. Adding @channel sends everyone a notification and possibly an extra email. So it is more likely that more people will be notified about the meeting.

the link still works, now to wait to see who shows up.

🎉 🎊 🥳

Sorry I missed it

i was out, but wanted to bump it

it's a Thursday again.

another Thursday

Another third Thursday

I haven't been logged in to Slack for a while.

it's a thursday

I’m at the Moondance music festival in Walker MN listening to a Beatles tribute band, so I won’t be joining tonight.

Is the voice call taking place?

I have not been there in ages. have fun though. I jave jitsi open

Where would I find the link, otherwise can you send it?

it's on the website https://meet.jit.si/TCRG

Both is better ☺️

no one has joined yet. there is a checkbox at the bottom where you have to agree to joining a open meeting that anyone could join.

Tomorrow is the third Thursday, but I won't be able to make it.

Has anyone worked with libraries to perform Modbus communications on a microcontroller? Modbus RTU or Modbus TCP/IP master/client or slave/server? I have been thick into it and the protocol is pretty amazing. Open source developed in 1979 by Modicon, now Schneider Electronic.

I am trying to use this awesome $99 4 axis motor controller indexer PLC with a Maplesystems HMI. https://teknic.com/products/io-motion-controller/

*Thread Reply:* I have written my own for the Atmel E70, but it was a work project.

I got to free geek and Charles works there. I told him about the online meetings and that the next one is tomorrow.

I broke my first soldering iron after barely using it. I bought the Pinecil soon afterward and after a lot of hesitancy due to lack of experience, I chose to practice with a breadboard first, then finally soldered headers onto my Raspberry Pi Picos. Ended up being fairly easy.

Hello everybody. Hear to pic your brains. I am working on a custom tape dispenser for work. The tape is 2" with a 2" core. A full roll is about 10 inches in diameter. I would like to sense the amount of tape left on the roll. I could put a potentiometer with a roller on an arm to sense. Or have the arm have an encoder (optical or magnetic) or have a linear hall sensor and a magnet. Or go non contact with a ir distance sensor or ultrasonic. The radius of the roll will change from 5 full to 1.25 empty. So just under 4 inches of sensor range required. Any thoughts? Any suggestions for a assy I could reuse? Like an automotive part or another assy that would work?

As anyone played around with the ST time of flight sensors?

*Thread Reply:* Like for measuring distances?

*Thread Reply:* Yes. When I was big into this hobby and going to a lot of our meetings circa 2002 we all dreamed of a light time of flight sensors to measure distance. What was once not practical now costs $15 on a break out board with headers and level shifting converters. They make them with several sensing ranges and upto an 8x8 sensing array kind of like "pixels" amazing! The one I got is for close proximity sensing 1 to 1300mm

*Thread Reply:* Can anyone help me with getting a AI software from Github running in python via Jupiter Notebook?

1. Github
2. Jupiter Note book
3. Python

*Thread Reply:* I am trying to run a AI program from Github to do some lip reading of a meeting video where we forgot to click record system audio. The program is on gethub and there is a YouTube video of a guy going over the install. I think he is running everything in JupiterNotebook. It has a bunch of dependices that need to be set up. I am having a hard time just getting started being I don't know Jupiter notebook or python. I need the how to install for dummies version of the tutorial.

*Thread Reply:* Can anyone help with that. If so call my cell

Those you are into GPS and mobile robotics Sparkfun has just released a high precision RTK mosaic-X5 that is "best in class." Based on the multi-constellation, multi-frequency, L1/L2/L5-ready.
