The microscope
Rob Turner donated this box of crap. |
It had this microscope lens and we wanted to display pictures on Alan's semi-flat display monitor. |
We took this box apart that has a CCD camera and an electronics board. |
This is the board that was attached to the camera. |
After much playing around the monitor still refused to work. So we had to actually look at the documentation. |
Jeff looking pretty sly. |
We switched to a different camera and a different monitor. So we tried to focus on a dime. |
Here is the first image we saw. |
We decided to mount the microscope in a vise. |
And then it was eaiser to focus on things and easier to adjust the lighting. |
The traces on the PIC-SERVO board we have been playing with the last few weeks. The reticule on the screen is 5 mils per division. |
The solder joints on the surface mount chips on the PIC-SERVO board. |
A real close up view. |
Some secret writing on a 20 dollar bill. |
The glowing surface of an LED from a fiber optic transmitter. |
Some salt crystals. |
Lasers and diffraction gratings
We found this grating in the trash. It is the servo positioning unit from an old harddrive. |
We shined the laser through the slots to create this pattern. |
And this one. |
And this one. |
After changing the focus you can see the actual slots in the grating. |

Jeff opened his R/C transmitter to make an adjustment to the servo pulse widths. |
