I’ve not posted much recently but that’s more due to the amount of projects I’ve been working on rather than the lack. Amongst these:
I will soon have ready a new easier to build version of the nixie chessboard, using printed coils and with a choice of SMD or all through-hole parts (I’ll probably end up using the SMD boards myself in ready-built boards, which will be much easier and faster to assemble using these). The PCBs haven’t been easy to make, special processing was required to produce low resistance windings that were at least as efficient as a hand wound coil with narrow tracks and spacing, even now the reject and rework rate is high and every coil is hand tested – one of the things taking up time just now.
Once the final bugs are ironed out and complete kits are available I’ll add another post with prices. This time availability will be off the shelf until sold out.
