4-bit counter
A 4-bit counter that displays the current turn number in binary.
The 4-bit counter tracks the current move number, resetting every 16 moves.
Note: requires a GRIB drive to function (sold separately).
open source
Wait, don’t click the “buy” button! If you have a 3D printer, you may be able to make this for free at home.

This mechanism is open-sourced under our GRIB protocol, meaning you can download the files for free and make it yourself.
An early access version of GRIB is currently only available to our Kickstarter backers. We expect to fully open-source version 1.0 in late August.
preorder
We’re currently fulfilling the original Kickstarter rewards. The estimated dispatch time for preorders is 7-8 weeks.
Each kit is manufactured in our workshop in Camden Town, London. We use lots of machines that make cool beeping sounds, and finish each kit by hand.
Kits will be dispatched in this order:
- Kickstarter backers
- Post-Kickstarter reservations (based on the date the reservation was made)
- Preorders (based on the date of the preorder)
