Computational Hardware for Pragmatists

ARITH-MATIC is a British computational hardware project and micro startup. We craft a range of DIY electronic kits which beautifully dissect the complex mechanisms of computation.

We have recently launched our flagship kit - the S1-AU Mk1 - a humble 4-bit arithmetic unit designed with 7400 series integrated circuits.

The kit is not only a pragmatic and tactile introduction to computational hardware and digital electronics, but also an excellent soldering exercise for computing enthusiasts, hobbyists and makers.

It contains all the through-hole electronic components you’ll need to build your own arithmetic unit and will enable you to visually trace binary operations through an array of onboard LEDs.

Along with the S1-AU Mk1 Operator’s Technical Manual, our beautifully crafted PCBs will guide you through construction and operation. All you need to bring is your trusty soldering iron and a steady hand.

Inspired by the homebrew computer movement of the late 70’s and early 80’s, ARITH-MATIC started life as a humble kitchen table project. It has since taken on a life of its own and turned into a fledgling micro startup.
