An Arduino-based tape player for old school computers like the ZX Spectrum, Dragon 32 etc. Hardware is compatible with tzxduino/arduitape and Maxduino firmware.
A new version of the classic Atari 2600 Keyboard controller, mostly because I wanted the overlays without paying for worn cardboard sheets.
Adapter for using a wired Sega Mega Drive/Genesis controller on an Atari 7800.
Schematic for the Advanced ROM MKII Adaptor redrawn, respin done as MKIII with more space for the Acorn Electron computer.
Joystick adapter that allows you to use common Atari-style joysticks (C64/Amiga/Atari) on your BBC Micro computer!
A PCB build of Rob Smiths Amiga DrawBridge, an Arduino-based solution for reading and writing Amiga floppy disks on modern hardware. Also includes version of Greaseweazle.
An attempt at building an automatic Amiga Mouse/Joystick switch (when used with Amiga port 1) - pushing the button changes the device connected. No more two-cable Merengue for me on the Amiga 500, forever more!
Adapter that plugs into the Game I/O connector on the Apple //e motherboard to add support for Atari-style joysticks, cables can be routed to the back of the case for easy access.
Prototyping card for developing new hardware for legacy Apple ][, //e and //gs computers.
Simple joystick tester, can be used with the common Atari 9-pin joysticks and paddles (tested using multimeter).
A PCB being made while watching Ben Eaters "Build a 6502 computer" video series. Includes the computer itself, a standalone slow clock and an Arduino Mega shield for the bus monitor sketch..
Created a simple PCB that can be used to transfer breadboard contents more directly to a PCB.
A HW build of the MT32-PI project, allowing you to emulate a Roland MT-32 using a Raspberry Pi. Includes enough additional modules to build a MIDI-mountain as well as adapters for connecting to most things retro.
My significantly more expensive, slightly less capable version of the Zimodem-hardware. Surfing the BBS-world at a blazing 1200 baud (or faster)!
Internet radio project, all kinds of unfinished and unusable.
A version of the DIAG64cart, this mainly changes components for the ones I've already got and adds a lot of LEDs. It's a blinkenlight project for diagnostic usage.
A recreation of the CP/M cartridge for the Commodore 64.
Changes Commodore 64 power LED so that it is green when I/O is used on system, reverts to red when done.
WASD-style joystick for vintage computers. With an added Arduino Pro Micro you can use it as a USB-keyboard, so if you wanted a DIY streamdeck or Macro-keyboard - then the C64 JoyKEY can do that as well.
A simple device that allows the connection of two Commodore 64 joysticks to a modern computer over USB (using an Arduino Pro Micro). The overall goal is to be able to use vintage joysticks with emulators.
Wanted a joystick switcher for my Commodore 64, so I built one by adapting C64 Mega Switcher for use with Atari-style joysticks. Supports secondary fire-button when using Sega Master System gamepads, even includes an auto-fire circuit.
Switchless kernal switcher for the common breadbin Commodore 64, "longboards". Reuses power LED for easier use.
An easier to solder version of the Lumafix board, components spaced out a bit more to make things easier on the beginner (mostly meaning me). Can also be used to bypass noisy signals on motherboard, wireing directly to modulator replacement.
Adapter for using Sega Mega Drive/Genesis controllers on a C64, with builtin port switcher so no more cable switching!
A simple modulator replacement for Commodore 64s with "longboards", complements my Lumafix version as well adding an audio connector for second SID.
I wanted a Pi1541 module that did not feel like I was handling bare electronics, so I made one that hides most of the scary bits (no 3d-printer required).
I wanted a Pi1541-module that did not feel like I was handling bare electronics, so I made another that manages to hide most of the scary bits without needing a 3d-printer.
I wanted an alternative to the SD2IEC on my Commodore 64, and I almost instantly took a liking to Pi1541 software. I did however need to design a board for it and this was the end result - even includes beepers, OLEDs and two IEC connectors
It's a tapuino, mostly because I wanted to build one. Uses an Arduino to load tapes on the good old Commodore 64.
C64 power supplies are ancient, they go bad every day so use protection!
