I’m happy to say that the chessboard kits are back on sale for new customers, using our online shop system. Currently, only the ‘nixie-less’ construction kit is available for purchase, but a pre-built option (with nixies) is coming soon.
The shop can be found here. Please bear in mind that we just installed all this shop software quite recently, and are still working out some bugs. Try not to lean on it too hard.
