Hi all.

It has been a while since I've updated this project page. This has been for numerous reasons but mainly because turning a kitchen table project into an actual product is seriously hard work!

I'm really proud, however, that the S1-AU Mk1 has been successfully launched and is now available via our new website: https://arith-matic.com/kits

I'm currently writing a (rather long) post about this experience - everything I've learnt, the trials and tribulations of launching a maker product, the strange world of compliance testing, the brilliant people I've met on route and the continuous inspiration I have found from other TTL-esque projects - I'll link to it from this page when it's ready!

In the mean time, if you'd like to find out more about the S1-AU Mk1, or arithmetic units in general, why not check the latest ARITH-MATIC note: Arithmetic Logic Units (ALU): An Introduction.
