Hi, and an extremely good 2021 to all of you.

We start off this brand new year talking about some totally unrelated and slightly more related new year's resolutions, a miniscule car fix, and glueing with a 3D printing pen. All in not much more detail than stated here.

Continuing on last episode's VGA generator board, I added a DMX512 interface as suggested by some people - thank you for the idea. I found Q Light Controller Plus (qlcplus) a nice and so far solid piece of software for controlling DMX devices from a laptop + USB/RS485 converter cable.

A potential issue (or at least in my head) when making interlinked devices like these, is potentially different ground-potentials depending on which power outlets you use to power networked your device. (See what I did there?) We talk a bit about how to guesstimate the possible magnitude of this difference.

Just for fun I made an xmas LED star-shaped decoration using an existing DIY LED driver board. Reuse everything, recycle success. Also, made a modular transparant acrylic home LED decoration: shine light into the edge of an engraved piece of acrylic. Of course there was failure, this time in the form of hygroscopic LEDs + laziness + oven = damage.

Finally, I made a small power switch PCB, to be placed in between USB power source and USB device: automatically switch the device off when the environment goes dark.

And remember: if YOU want to make this podcast suck less, please send comments, rants, complaints, threats and/or praise. :-)
