I've got a large box of hardware for inventing and prototyping. This includes arduino boards, adafruit wearable boards, some spark fun dev boards, cellular boards, esp8266 and lots more. There's a basic stamp learning kit, including a very old computer for running the software, and programming an old pic programmer. There's a bunch of passive components, sensors, breadboards, and soldering supplies. Haven't tested it all for function. Perfect for young learners and experimenters. Make me an offer for all of it, as is.
