Quick build instructions for Hackteria Remix Raspberry Pi Microscope
Mount the Camera
- Attach 3D printed camera holder to baseplate using M3 bolts(16mm)
- Attach camera to holder (NOTE: These M3 bolts were too large and I had to drill out the camera mounting holes -- should get smaller bolts for future versions)
- Attach optics mount to camera bottom
Build the Stand
- Attach back-holder to baseplate
- Attach back to back-holder with slide (20mm bolts + washers) so it can slide but stays in place
- Screw in objective to set table height. Objective tip should be at roughly the same height as top of table. You can get this precisely with combination of slide and notch height.
- Attach table
- Add feet -- feet elevate above screws and dampen vibration
Attach the Camera
- Plug ribbon into camera
- Plug ribbon into pi
- Connect the pi to laptop via USB to provide power
Attach the Focus Bolt
- The carriage bolt acts as a lead screw. Rotate it through the hole and screw it down until it touches the base plate
- Hold sample plate in tension with rubber band
Build a Light
- Extend the wires on the battery pack. The wires coming off of the battery pack are not quite as long as we would like them to be so we start by attaching extra lengths of wire. If you have a soldering iron you should solder these connections. Do this for both the red and black wires.
- Attach the LED. Red wire goes to the long lead, black wire goes to the short lead
- Glue to coathanger wire. This provides a flexible mount for your light
- Bend the wire to position the light. It should point directly down, facing into the objective lens.
- Take some pictures -- use binder clip to hold slide in place and bolt for focus adjustment. Make your light is pointing directly into lens to get enough light.
