Upright DIHM
As outlined on the Description page, we made our microscope out of an aluminium diecast box, a piece of profile extrusion and some plastic blocks. The designs are available via our Downloads page. Once all the parts are acquired, the following assembly process should be used. We have provided step by step instructions, below.
Assembly
Connect the Base and Profile Extrusion
Tap the holes in the profile extrusion so that it can be screwed onto the base as shown.
Prepare the Raspberry Pi
Connect the Explorer hat PRO and Camera Module V2 to the Raspberry Pi 3 as in the images. Note that we removed the lens from the camera.
Connect the Raspberry Pi
Screw the Camera into the position shown using nylon (non-conductive) screws. Connect the power cable to the Pi through the back of the base. This is also where HDMI/USB connections should be made.
Build the Circuitry
We used a 635 nm laser diode and corresponding socket from Thorlabs. Soldering the socket prevents heat damage to the diode itself.
Connect the Laser
Feed the wires from the circuitry through the profile extrusion, as shown, then connect the positive to the Explorer Hat's 5V output and negative to ground. At this point, the Pi can be sealed inside the diecast box, by adding the base plate.
Add the Platforms
Attach the screws and fixings (we used Item profile extrusion, so we used their fixings) to the platform.
Congratulations!
