Unimplemented Trap

All you need is a bunch of logic chips and a few Raspberry Pi Picos and you’ve got a very usable Apple II.

Options for punching data onto paper tape in 2025 are quite limited.

It's only feature still is telling the time, but it does at least have Wi-Fi now...

A machine that gives the impression that there is more going on inside than is actually the case: using CMOS shift registers to produce psuedo-random numbers with Nixie tube readout.

My PiDP-8 and 11 replicas are now properly mounted up in this small cabinet made from stuff I had laying around.

A tiny games console built around a Noritake Itron Gu20x8 vacuum fluorescent display and powered by an Arduino nano.

An Arduino Nano based 16-bit integer calculator designed for helping with 6502 programming projects.

A sort of 8-bit calculator that takes hexadecimal input and displays the results in both hexadecimal and binary.

I came across this weird chip a few months ago.

A quick weekend project to see what I could make work with the parts I had laying around.

I've been using the Clarke brand vice-mounted sheet metal brake for a few years now and it's been useful for various projects and handled both sheet aluminium and steel without issue.

ebd is a simple tool I wrote in Python for viewing the source of a binary file in hexadecimal.
