Qty | Part | Cost |
---|---|---|
1 | PL2303HX or similar | 3.00 € |
1 | IR-Fototransistor | 0.10 € |
1 | IR-LED | 0.10 € |
1 | 4k7 | 0.10 € |
1 | 1K0 | 0.10 € |
1 | Housing (3D print or laser cut) | 0.50 € |
The USB to Serial converter PL2303HX provides 4 wires for the signals GND, +5V, RxD and TxD as shown in the schematic The TxD diode is optional and not supported by the software.
I used a laser cut housing based on 2mm white acryl. The design was done with Inkscape.
The S/W is written with XOJO to support all major OS (Windows, OS X, Linux). As I have just now only a license for OS X I can't provide binaries for Windows and Linux.
The S/W has mainly the same functionality as the original one.
