After considerable to and fro I finally ordered a 7-color e-ink 1 display for the raspberry pi from pimoroni 2. With the help of the official repository 3 putting images on the the display is quite easy. The repository also has code for other e-ink-displays from pimoroni. inky impressions display showing a photograph of paris With about 85mm x 115mm it is comparable to typical e-reader display sizes. Although the glass leads to a different look compare to the matte e-reader displays.…

what is sed? sed is a “stream editor” in the commandline. It can do a lot of things and I wrote down some basics examples here (to avoid re-googling them in a few months). A great and very thorough guide can be found elsewhere [0]. I only post the most useful examples that I needed so far. sed typically works by reading an input string, looks for patterns and does something with these patterns.…

In order to avoid this hassle and not waste so much fucking time again (and hopefully help some lost souls on the internet in the process) I’m writing everything down here. enabling the audio-shield For the DAC2-Pro XLR in the “/boot/config.…

Last month I started working at Dark Matter in Berlin. Dark matter is an exhibition space showing various kinetic audiovisual art-pieces conceived by Christopher Bauder. They mostly use special DMX-controlled winches to move glowing light-elements precisely up and down. Collectively the winches create moving and morphing objects in space in sync with musical soundscapes. My favourite pieces there involve precicely moving objects in order to create moving objects that take up space.…

Shelf design done in python. Last year I started to build one shelf to fit all my stuff into. The idea had been floating around in my head for around 5 years. The idea was to build a shelf conceptually turned sideways by 90 degrees. Usually shelves consist of vertical wooden planks with horizontal boards between them to put stuff on. This way we can vary the widths of columns of shelves and the heights of each compartment within one column.…
