If one is going to build a cyberdeck, you might as well make it look like a cyberdeck.

Yaduino Cyberdeck

This is based on my “Yaduino” Arduino Uno clone, my first MCU system design project using the good old Atmega328P. Thought I’d do something fun and turn one of the boards into some sort of “cyberdeck” complete with net access courtesy of an ESP-8266. Wrote some quick and dirty code to manage menus and launch actions across three screens. Also has some nice text effects for good “cyber” measures.

Now that's a good looking PCB, if I do say so myself.
Brownouts resolved with a 100uF bypass cap across the ESP-01 module supply pins.
An assembled Yaduino board, complete with a 1602A display and ESP-01 module plugged in. Note the red bodge wire to connect VCC on the charge management IC.
A couple of assembled Yaduinos complete with custom 3D printed enclosures. One of them sports an OLED display instead of a 1602A.

The Yaduino - An ATmega328P playground

So this is my first stab at designing a microcontroller board. I call it Yaduino - Yet Another Arduino (the missing r is deliberate!) :)

Converting Amiga keyboards to USB

Wouldn’t it be cool to use a big-box Amiga keyboard, such as one for the A3000 or even a CDTV keyboard, with a modern computer using USB? Maybe even use it with a next-generation Amiga, like a Pegasos II running AmigaOS 4.1 FE? Well, that’s exactly what I did, and it works great. In fact, I’ve currently plugged in a CDTV keyboard into my headless Synergy server’s USB port, along with a mouse, to share a single mouse and keyboard across multiple machines; namely, an Amiga 1000 and a couple of Pegasos II systems running AmigaOS 4.1 FE and MorphOS.
