This is a bit off topic from where this thread is going, but I need a little help if anyone can provide it. I have 2 k16s, fully assembled and visually everything checks out, but neither one is recognized when the USB is plugged in. No blinking LEDs, just buzzing caps.
If anyone would mind helping me out, I'd have no problem tipping what I can or test these via your pool/address of choice.
it sounds like you might have a short somewhere in the power supply output. Did you measure voltages with a multimeter? Do you have an oscilloscope?
