My Fire Fighting Project
This project is based around Micro-Mo gearhead motors, a BX24 processor
and 8" diameter plastic disks. I started this for two reasons.
First, because I wanted to play with a Basic Stamp 2 or a BX24 processor.
Second, because Brynn is trying to get everyone fired up about competing
in a local Fire Fighting contest.
This is how far I've gotten. I haven't attached the motors and wheels on the bottom yet.
They will be mounted with 1" extruded aluminum angle brackets.
The bottom platform and one ni-cad pack. I may use two of these ni-cads to give
me 24V. The motors are rated at 18 volts. Or I may run the motors and electronics
off the same 9 volt supply. I'll have to see how well the motors perform at
the different voltages.
This is a Jameco JE24 protoboard. I got it at ABC Electronics for $17.99.
I sawed it off to fit the 8" platforms.
I also cut the corners off, again to make it fit the round profile.
I also mounted a 1" aluminum angle to mount the switches and the RS-232 connector.
One switch is battery power and the other is the download enable for the BX24.
There is a pushbutton for the BX24 reset.
The connecter is a female DB9 for the serial cable to the PC.
Bottom view of the protoboard. You can see the two battery holders I got from
Radio Shack. One holds 2 "AA" cells and the other holds 4 "AA" cells which
gives me 9 volts. They are attached with double back foam tape. The voltage
regulator is also visible. The BX24 has its own regultor, this one is for
the rest of the logic.
I currently have a BX24 processor and a Vector 2X compass wired up.
Mainly just to test each one.
I also have an HP HCMS-2914 self-scan LED display.
But I probably won't use it.
I will probably switch to an LCD display if I decide I need a display.
The pot is wired to an A/D input for testing.
The Micro-Mo motor, pulley and wheel before I started.
The wheels are sold as "high speed" airplane wheels at
hobby stores for about $10 per pair.
On the left you can see the motor, pulley and wheel. On the right is a pulley
bolted to a wheel. At the top is the new wheel attached to the motor.
