I’ve always wanted an Apple Macintosh SE/30. Released in 1989, they look quite a lot like the other members of the original “compact Mac” series, but pack in a ton of interesting features that the other compact Macs don’t have. This is the story of my journey to getting to the...

Way back when, I made a cool but basic paper sculpture (in Maths is Fun and Useful) by hand, using a perl script for the shape template. For cultural reasons, I wanted to make a gift out of paper and it had to be Heaps Good. I had finally got access to a laser cutter (omgomg)...

Built October 2018 I used to hate Cathode Ray Tubes. As a kid in Europe, everything flickered at 50Hz, or made a loud whistle at 15.625KHz (back when I could still hear it). CRTs just seemed crude, “electro-brutalist” contraptions from the valve era. They were heavy, and...

Back in February 2014, it was a cold (but dry) winter’s night and we decided to warm our hearts with some science. Our experiment was to observe the conduction of electricity through a pickle, using salt ions. We connected a pickle to the mains supply. Pickles have a strong...

This project was completed in June 2015. Wow, is it 2017 already? In this post, I’d like to say that I wrote a useful little bit of software and built up a crappy hack to demonstrate it but, secretly, the crappy hack came first and I’ve retroactively found something vaguely...

This is the obligatory “first post on new platform” post, coupled with a bit of “first post in 4 years, I’m still alive”. The original axio.ms site was a very HTML1.0 affair and while this was kind of intentional-tongue-in-cheek-chic, it was also a PITA to update. It wasn’t...
