Sharing the project for greater visibility:https://github.com/Jartza/PS2toAmigaPlease go support the authorPS/2 keyboard protocol in it's basic level isn't that hard, it is bidirectional synchronous serial port with clock (CLK) and data (DATA) lines, communicating with PS/2 keyboard using microcontroller has been done multiple times already - which is why I chose to use PS2KeyAdvanced library for Arduino to handle that task - I didn't want to re-invent the wheel, and I had already used PS2KeyAdv...

Varta Replacer (Varta to CR2032)
Jun 15,2026
Sharing the project from:https://github.com/RetroNynjah/Varta-ReplacerThis simple circuit enables use of a coin-cell battery in place of a dangerous leaky Varta battery in your favorite vintage computer. This kind of device has many names but is often called Varta Replace. Varta Killer or similar because Varta rechargable batteries were common in many old computers including many of the Commodore Amiga computers. Those old Varta batteries are famous for leaking with severe corrosion as a result....

PaulaNET - Amiga Wifi Network Adapter
Smith May 13,2026
PaulaNET is a simple Wifi Adapter for the Amiga that connects via the Floppy Drive Port.This is more suited to low-end Amigas although will work on all of them. Because the floppy drive communication all happens using DMA, this device can (currently) acheke around 43kbytes/second with very low CPU load.Notes: X2 OR DSUB1 should be fitted, not both. I recommend using a DB23 connector, pushed into the side of the board and soldered in place.The Pi Pico must be a "Pico W" or "Pico 2 W" (Pico 2 W Re...
