In this video I repair a Soar brand, model 1500 cable length checker. Also known as a TDR meter or 'Time Domain Reflectometry' meter.
It sends a pulse down a wire and measures the time taken for the reflected pulse to return to determine the distance to the end of the wire, or the break or short circuit. Great for finding where to dig or cut to find where a cable is damaged. ... https://www.youtube.com/watch?v=WyXNg9dEoZs

In this video I build another electronic clock kit! This time it's a LED dot matrix display and included a laser cut plastic enclosure. I also offer a few surface mount soldering tips and useful tools and gear.
It's a decent little clock with a nice LED display, time, temperature, and light sensor.
