The economics of selling hardware are unfortunately not in my favour. To make it halfway viable I’d have to at least buy or make a reflow oven and rig a setup to apply the solder paste by stencil, otherwise it takes way too long to assemble a board.

I’ll have a closer look at assembly houses or full service providers like circuithub, but it seems that I’d need to have batches of at least 100 units at a time to drive down cost, which would be quite an investment.

I could probably provide single units hand-made with some lead time, but that’d be more a “labour-of-love” thing (or quite expensive).

Kits are an option. But, not many people would attempt hand assembly and the inevitable handling of returns for failed attempts would certainly kill the fun.
