What do you guys think of something like this? All the jumper and resistor hocus pocus wrapped into a neat package.
I made a couple for friends and myself. The unit below would be a 10amp version due to the binding posts rating, and Its only using the one yellow wire from the 20 pin connector.
This particular one is only wired for 12volts. Has an LED so you know its on. This one has no switch because we just unplugged the thing when its not in use.
I wonder if others are interested and if its worth my time to offer somethiing like this since I don't know what people would pay for it.
