I’ve been surprised at the number of requests for black laminate PCBs, when I first mentioned them I expected maybe 5 or 10 sets to be sold but they’ve been a little more popular than that. I have enough black laminate for the kits I’ve invoiced but very few more. I can buy some but the minimum order is far more than I’ll need to finish the rest of the orders.
An alternative is to have the PCBs maufactured and coated with black solder resist. Again to reduce the cost I would need to pay for a batch of 250, though I would change the design again to use 4 identical boards per kit with a small stub to hold the power terminals. Still this will be enough for over 60 more kits. This would also remove the choice of PCB type and price, it would be the black option or nothing. It will make assebly easier though as they’ll be be marked with component positions.
The baseboard currently drives IN-7s which aren’t as common as they used to be 😉 but almost any small/medium nixie or VFD display can be used without modification, only the piece base PCBs will need to be altered. This means I could use the same board with different piece sets in future if there’s enough interest. On the other hand I don’t want to destroy the uniqueness.
What are your thoughts?
