I found these two test jigs for sale at a local business that was relocating. They would have been used as part of the quality assurance procedure for smart bike lights. Later we might go into more detail on the firmware, or repurpose the formidable hunks of metal for another project!

This time we’re hurtling through the layers of technology that make a graphics tablet (pen tablet) work, from operating systems politics to electromagnetic induction. I’ll be looking closely at two tablets, the Wacom Intuos Pro and Huion H610PRO, and going into a full teardown on the Huion.
This video takes a close look at those little chirping sonar cylinders that might have helped your robot avoid bumping into furniture. They’re sort of like a microphone or a speaker, but looking closer they seem more like a tiny tuning fork with a hat.
I had another video planned, but today the yak stack needed tending after my trusty 10 MHz signal generator started buzzing horribly. Today’s video will be a teardown, repair, and mini-review of the 2007 vintage Protek B8010FD.
