On one hand, I’m having a lot of trouble procuring the nand circuits to build things, and also most of the books seem to just show a schematic and assume the user knows where to find the parts for it and assemble them. Also, its quite a pain to solder together every single test circuit.
Have any of you used these kinds of kits?
