How do you process payments?

What happens if I have problems constructing the kit?

If you have problems constructing the S1-AU Mk1 we can help. Firstly, we provide some easy to follow troubleshooting tips through our ‘Operator’s Technical Manual’. However, if this doesn’t solve the problem you can contact us via: support@arith-matic.com and we’ll do our best to help.

In this instance, we’ll ask you to provide a high-resolution image of the back of the S1-AU Mk1 which is in sharp focus and taken under bright lighting conditions. We will then do our best to work with you to troubleshoot the possible problem(s).

S1-AU Mk1 owners are welcome to send the kit to us for a full inspection should a problem occur, but you’ll need to pay the postage fee. If we subsequently find you have received a faulty component, we’ll refund the postage and offer a repair or replacement as appropriate.

The S1-AU Mk1 uses a USB cable - is it programmable?

The S1-AU Mk1 is not programmable - it requires manual operation through onboard switches. The USB cable is only used to deliver power to the unit, so there is no need to rely on batteries.

Is the S1-AU Mk1 shipping worldwide?

We are currently only shipping to the UK, EU and US thorough our website: arith-matic.com. As a micro startup, shipping the S1-AU Mk1 worldwide would add additional challenges in terms of logistics, customer support, troubleshooting, and in meeting local compliance regulations. As such, we've decided to provide a limited release so we can offer an experience to our customers that we are completely confident in.

Shipping outside these regions may be available through our distributors, however stock and availability may be limited.

What are the other kits in the series?

Series 1 will include three kits: an Arithmetic Unit, a Memory Unit and a Control Unit.
