Question
Kaizen
I had to make up a number of 50 Pin IDC (PCB interconnect) cables today and wanted a way to quickly test them for open curcuit and short circuit, I also have a number of used ones I wanted to test as well.
The crimps are staggered so the first one is connected to the bottom row and the next one is connected to the top row so I split the LEDs between each row so that if there is a short between two adjacent cables it'll light one of the LEDs on the opposite side and if there's an open circuit then one LED won't be lit.
A double pole switch powers each bank so it's just a matter of flicking the switch to check each side. Works a treat and didn't take long to knock up.
