You don’t need access to fancy test gear to check and fault-find computer data cables. Instead, this simple device will give a quick indication of the status of point-to-point cable wiring; ie, ...

Frennzy: "If you want to *build* a cable tester, then build one. Learn about electronics, and expected termination patterns. Learn about impedance and frequency testing. Learn how to design and build ...

Microcontroller-based circuits for testing cables, sometimes in conjunction with a PC, are easy to use and very flexible. For the hobbyist, however, the complication of such devices is not justified.

Ever wondered why your Arduino wasn’t programming, only to find out that the cable doesn’t have any data conductors? Worry not, [Spencer Maroukis] has got you covered with the USB Sleuth Cable Tester!

I have a drawer full of USB cables and every time I want to connect a device, I have to try them out. USB-C was supposed to simplify things: One cable for everything, that was the promise. In practice ...

USB-C cables get no respect. Most people shop for the lowest-priced cable and call it a day under the assumption that they are all the same. They’re not though, and here’s how I weed out the good ...
