I just posted on github a little project that takes a cheap surplus (my last ones cost $5 NOS) IBM iPoint IR keyboard and converts it to PS/2 keyboard protocol using a cheap STM32F103 "Blue Pill" and a 3-terminal 38KHz IR receiver. I'm currently writing the USB version which will support the "nipple mouse" as well. The keyboards aren't bad--they're made by Silitek ca. 1992 and have a decent feel for a rubber dome keyboard. The point is that with modern MCUs, any IR stuff is easy-peasy. My little Chinese LCR tester even reads and displays IR codes. --Chuck
