Watch Time Lapse!

Time lapse of assembly

Current version is designed for absolute simplicity so as little as possible SMD components and parts with large footprints are used. Start assembling by soldering the smalles parts first (MMBT3904 + MCP3426).
Then add THT passive parts piece by piece according to description on the PCB and the BOM.

Most important:

1. Place IRL81A (IR Emitter) and LPT80A (Sensor) in adapters D and E, seal with hot glue and solder wires to the corresponding vias on the PCB. Long leg is anode (positive).
   
   
   
2. Place adapters D and E in the case A and B. Emitter to top case. Seal with (hot) glue or tape.
   
   
   
3. Put pump in place and do a test run for leakage.
