The small PewPew has been just approved on Tindie, so you can order it already. The package will arrive tomorrow, but the approval process takes some time, so I started earlier. I wouldn't be able to send it on a Sunday anyways.

If you need a larger quantity for a workshop, contact me directly, and we can arrange it.

The product on Tindie still has the photos of the prototype — the final version has a red PCB and green buttons. I will update the photos when the package arrives. The final price is also a little bit higher than I initially anticipated, due to the duty tax.
