This month’s HackSpace Magazine includes a pair of my reviews, the first looking at a computer that’s also a ruler – because that’s not only a thing but the second thing of its kind to come from the same designer – and a new set of charitable Top Trumps-style collectable cards.
First, the ruler-computer. Designed by Brads Projects, the Digirule2 is – as the name suggests – a second-generation design of a compact microcomputer which is also a functional ruler. Printed onto a single circuit board and built around a PIC32 microcontroller, the Digirule2 is inspired by the classic MITS Altair 8800: its memory is displayed on a series of LEDs, and is programmed one bit at a time using push-button switches.
Where the Digirule improves on the Altair, aside from being considerably more affordable and not taking up a huge chunk of your desk, is in having memory slots for saving and loading programmes. These slots come pre-loaded with demonstrations ranging from simple reaction games to a neat persistence-of-vision hack, while the edges of the board are printed with measurements – in binary, naturally – in both centimetres and inches.
The cards, meanwhile, are something a little less technical but no less geeky. Designed by 8bitkick and sold by the Centre for Computing History to fund its restoration and preservation works, the Games Consoles Collectable Cards partner high-quality colour images of classic videogame consoles with statistics that can be compared for a nerdy game of Top Trumps. They also partner well with the Home Computers Collectable Cards, an earlier release now repackaged to match, though sadly the two decks use different statistics and thus can’t be combined into a single mega-deck.
