I got the idea myself that an Arduino would be perfect to perform test of USB-cables but I had no idea how much and I would never have gotten so far as Doug has with his Touch Screen Cable Tracer! I was immediately sold (as we say in Denmark) when I saw his construction and ordered it right away. Doug was also really helpful when my local postal service (PostNord Denmark) almost did everything wrong and (almost) returned it back to New Zealand but I was lucky and got it by chance from the post office. The Touch Screen Cable Tracer is very well built and does everything as advertised.
Wonderful cable tester for USB cables of all sorts. I bought the already assembled version and it was extremely easy to complete. Caution though - you must get the display specified for it to work though. I tried it with another display and finally ordered the correct one from China. Now I'm happily using it. Wish it had the option for a rechargeable battery and a power switch though!

Thanks for the feedback, a great idea to have a battery option. I've included a larger 3d model case in the build instructions for those who choose that option. Doug
