    2019 Bigger Projects

    • #Club Matrix
      Array of 10 8x8 WS2812B LED matrices, controlled by a Raspberry PI through a DMA library. Images can be send as UDP packages to the matrix, if you happen to know the IP address.
    • SX-64 inspired Raspberry PI case
      Inspired by portable computers from the 80ies, I started to build a case around a Raspberry PI with 10mm extrusion profiles and lasercut panels to mount stuff to. https://www.youtube.com/watch?v=vXGr7-_U_tY
    • #400 LED XY oscilloscope 
      For another video done for "elemen14presents", I cobbled together schematics out of Forrest Mims III's engineers notebook to make an LED oscilloscope that has 20 x 20 10mm LEDs.

    • #LED handheld 
      This monster pixel game uses some tricks like charlieplexing, soldering LEDs upside-down to shine through the PCBs and hours of sanding on a 3D printed case.
    • plenty other projects for element14presents
      Here's a list of all my appearances as a video host for element14presents, plus some extra episodes of livestreams of the makercast - podcast that me and some other youtubers started.

  • SX-64 inspired Raspberry PI 4 thing

    So I've made this thing for element14 presents, never really had a set and forget PI to work on. I do like the optics of the SX-64 very much and all the other "portables" from the 80ies. I went with makerbeams 10x10mm aluminium extrusions for the frame and some lasercut MDF to hold everything together. Still needs an enclosure, but I'm pretty happy with it.

    I tried to make the 2K display work, but it was too flickery and I couldn't get it to work properly, so I switched to the official display.
