 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.

+Depending on the thickness of your wiring you may not need all layers. In my example I only used 4 pieces.

-=== Laser Cut ===
+==== Assembly ====
+Cut and engrave on your laser cutter of choice. Prepare the small piece of PCB (perfboard). Glue the IR transistor (dark blue)and the IR LED. The flat part should be on the left for each. Solder the parts and the SMD resistors as shown on the picture. Last but not least connect the four wire of the PL2303HX.

 The S/W is written with [[https://www.xojo.com|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.
