PC floppy disk interface for Amiga (miniature)
RetroTek Jul 03,2022
This project is a project made to use PC floppy disk drives in the Amiga. No operation will be done on PC FDD, it will be connected directly. The project was designed as an external disk drive for the Amiga.This project is a shortened version of my project in the link given below upon request.https://www.pcbway.com/project/shareproject/Amiga_External_Floppy_Drive_with_PC_FDD.html

Temperature Controlled 12V Fan for vintage computer
kinmami Jun 01,2022
A low-cost temperature-controlled fan.BOM list in the attachment.It can be used to control a 12V / (up to) 1A fan inside the Amiga PSU or (any computer) case, even if the motherboard hasn't a designed PWM control.Smooth operation.The duty cycle is regulated between 76% (room temp) to 97% (+100 degrees Celsius).The PWM frequency is controlled between 400Hz (room temp) to 700Hz (+100 degrees Celsius).

Commodore Amiga 2000 3000 4000 Tick signal generator and -5V rail Power Supply Unit ATX ALL-IN-ONE
kinmami May 31,2022
This circuit replaces the missing TICK signal for the system clock of the Amiga 2000 / 3000 / 4000.This small circuit generates from the power line frequency of 100~240V a suitable 50/60Hz TTL signal, which makes the system clock run more accurately.In addition, it generates from the existing -12V a low noise fully protected regulated -5V / 1A line for Amiga 2000 / 3000.BOM list https://www.digikey.com/en/mylists/list/9HXPMBOTSE

It's-a me, Mario
Arnov sharma May 30,2022
Hey what's up folks, this is my version of Super Mario Theme Player powered by an ESP8266 MCU.I Made the PCB themed after Mario the Plumber himself, On the TOP Side it's just an Artistic PCB but on the BOTTOM Side I've placed all the important components that drives this board.For Powering this setup, I added an ONBOARD USB Pad for making a USB on PCB.As for the Super Mario Theme song, it's a Note Based Sketch that plays melodies similar to Arduino Note Sketch.This Board is made in such a way th...

PiStorm600
Lemaru May 27,2022
This is a Amiga 600 compatible rework of the original PiStorm Rev. B board. It clips over the 68000 CPU of the A600 using an inverted PLCC socket in the same way as many other A600 accelerators. Once fitted it disables the onboard CPU and allows the CPU emulator that it running on the Pi (Mushashi or Emu68) to take over.For details on installation, bill of materials, and information regarding PLCC sockets and required modification, please head over to the project page on GitHubhttps://github.com...
