Project: Chess-Composer
Tech: Vue.js, Chess.js, Tone.js, PWA
Task: technical concept and implementation

What does a chess game sound like? This deep question lead to this experimental application, which converts PGN chess notation into musical notation, creating sounds live via real-time software synthesis and sequencing. It applies music theory concepts (which needs more elaboration).

The Progressive-Web-App (PWA) runs completely offline and is installable on mobile devices. Current status is early alpha, more like a prototype. It only runs in modern browsers which support Web Audio API. Please don’t run any other audio/video content in your browser(-tabs). If you notice sound distortions reload the page.

Raspberry Pi 3 Altoids case

I recently got a Raspberry-Pi 3 Model B as a development platform for Internet-Of-Things projects. The very first task was to give it an adequate housing, so I decided to put it into an Altoids tin.

raspi Altoids-tin






tools used:

  • sticky-tape
  • permanent marker
  • opinel no8 carbon steel knife
  • sandpaper

I transfered the shapes and locations of the Pi´s plugs onto the sticky tape via the marker.
The tape was put on the Aldoids tin afterwards and the shape was cut out with the Opinel knife. Although the Opinel did the job quite well maybe I should just use a dremel next time.


raspi-sandingWell, actually it turned out the PCB was a bit too large to fit in the Altoids so I sanded down the edges of the PCB almost up to the screwholes. Of cause you have to pay attention not to destroy any circuits or components.

To isolate the board from the metal case to prevent shortening components I put a plastic card at the bottom of the tin.

re-fuse – FENDER® FUSE™ Preset-Manager

Projekt: re-fuse, FENDER® FUSE™ Modelling-Amp Preset-Manager
Tech: Adobe Air, XML
Link: Fuse-Produkte

Bei den FENDER® FUSE™ kompatiblen Gitarrenverstärkern, z.B. Fender® „Mustang“-Modelle, handelt es sich um sog. Modeling-Amps mit programmierbaren DSPs. Da die FENDER® FUSE™ Software von Haus aus keine komfortable Verwaltung der Sound- und Effekt-Presets bietet habe ich diese Cross-Platform-App für OSX & Windows zum Bearbeiten und Sortieren von Presets geschrieben.
