New post on my blog: I built a joystick using a 2-layer PCB and some strain gauges. The #StrainStick works very similarly to a TrackPoint. There's also a small demo software that lets you use it as a mouse by connecting it to a CH32V203 dev board.

The Strainstick - Building a joystick from strain gauges

The Strainstick is a joystick which works by measuring pressure, not movement. It can be built from a single 2-layer PCB and a couple of cost effective parts.

I wanted some mounting capabilities on my desk, so I added a SKÅDIS to the side. I used a 36×56 cm panel, which I cut in half. Maybe this is useful for others. You can find the printed parts at:

I did another take on SMD storage containers and added wire storage. Fully 3D‑printable and customizable, you only need an aditional spring per container. There’s even a mount for IKEA Skådis ;)

Hope it helps you stay organized!

USB video capturing for the Open DMG Display! I adapted the GB Interceptor approach for the #opendmgdisplay, making it likely the first #gameboy IPS mod with integrated USB video output.

Big thanks to @DiConX !

USB video output for the Open DMG Display

USB video output has been added to the Open DMG Display. It is now possible to capture the original display signal via UVC on a PC or smartphone.

Turning a low-cost CH32V305 MCU into a Game Boy Advance (and Color) USB capture device, with no extra circuitry required.

Captures full-res RGB565 at ~60 Hz and streams it over UVC in YUY2. A fun look at combining basic peripherals to extend the capabilities of a simple microcontroller.

This arrived today, and from what I’ve read so far, it’s the best overall reference work on embedded system hardware and software that I know of. It doesn’t go into great depth, but it offers an overview of many aspects of embedded system development and provides the right keywords to dive deeper. If anyone is interested, here is some more information: https://effectiveelectrons.com/book/

This week, I finally found the time to hang up my Brickpress prints. I’m still amazed by the way thoughts are portrayed and by the craftsmanship of the execution. Thank you very much, @GuidoKuehn .
