Walkthrough
This guide is for the general purpose 12V PCB which was designed for simplicity so as little as possible SMD components and parts with large footprints are used.
1. Start assembling by soldering the smallest parts first (MMBT3904 + MCP3426).
2. Then add THT passive parts piece by piece, the Pi Header (or connector) according to description on the PCB and the BOM.
3. Put IRL81A (IR Emitter) and LPT80A (Sensor) in brackets D and E - refer to overview above - seal with hot glue and solder wires to the corresponding vias on the PCB. Long leg is anode (positive).
4. Place adapters D and E (refer to overview above) in the case A and B. Emitter to top case. Seal with (hot) glue or tape.
5. Put pump in place and do a test run for leakage.
6. Secure the raspberry with 3d printed brackts
7. Put the rubber band (cut down to two peaces or use one) to prevent air leaks onto lower case, also add screw threads if you want to.
8. Put filter paper on top of the rubber, screw the intake part on top and continue with software configuration.
