LEGO Mindstorms NXT Cable Checker
I needed a LEGO Mindstorms NXT Cable Checker to allow me to Verify my NXT Connector Cables for connectivity or faults. A tester is particularly useful for when you are crimping your own cables. I picked up a cheap Network Cable checker of eBay for $2.50, and hacked it to suite NXT Cables. Unfortunately it wasn't as easy as I first anticipated!
I was initially going to swap the six wire sockets in the 'Tede Tester' above with NXT type Sockets, but they original sockets were not standard on the Printed Circuit Board. My next approach was to attempt to grinding the original socket into shape to suite a NXT Plug. This also failed as the socket walls were rubbish and fell apart!
Inside the Cable Tester
My final choice decision involved removing the original sockets and replace them with hook-up wire to the replacement NXT Plugs. The old plugs were easily removed thanks to a single-sided PCB.
As can be seen below, it all went together after the initial hassles. Unfortunately, I now need to find an alternative case for the tester as the PCB's and Sockets won't fit in the original case.
Testing the LEGO Mindstorms NXT Cable Tester
I also removed the extra 2 LED's from each PCB as they are no longer needed as an NXT Cable only has six wires. And Yes, it all worked as it should.
With $2.50 for the original Tester and the same for the two NXT Sockets, I've ended up with a handy LEGO Mindstorms NXT Cable Checker for my tool box. All be it without a case as yet.
