I was asked about selling the computer bricks in kit form, and gave the same answer I've given before - that the assembly process is really fiddly, requires materials that most people don't have at hand, and is very challenging to get right on the first attempt. But what if I made just the circuitry available as a kit? Would anybody be interested in this as an object in its own right? It clips on to Lego studs & has two capacitive touch buttons, a 72x40 screen, and an RP2040 stuffed inside it.
