| Assembly Instructions<br>
| |
| | |
| 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.

| # 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). [[File:Sensor-emitter-brackets.jpg|thumb|left]]<br clear=all>
| |
| # Place adapters D and E in the case A and B. Emitter to top case. Seal with (hot) glue or tape. [[File:Brackets-in-lower-case.jpg|thumb|left]]<br clear=all>
