Slowly figuring out some 1KV power supply monitoring and switching: in orange the voltage in V and in blue (roughly) the current in mA.

The proceedings of the first symposium on the history of semiconductors, held in 1979 when most of the people involved in the beginning were still around.

Fortunately I was able to repair this fairly scary 1KV power supply.

Very nice exhibition 'Uncharted' in Iselp in Brussels, curated by Camilla Colombo of Ohme. Pictured an intriguing work by Noémie Goudal.

Today I was introducing ArtScience approaches to a nice and interesting group of PhD candidates researching chirality-induced electron spin selectivity: I am more familiar with talking to artists about science than the other way around !

Very nice to be able to see some outcomes of the clay PCB workshop at Creative Coding Utrecht yesterday. This is a project on decolonizing hardware by Stefanie Wuschitz and Patrícia Reis, sourcing materials locally as much as possible.

Crystals in the mail ! Ten supposedly almost perfect cubic crystals similar to those used in the 1930s experiments that I am attempting to replicate/reenact.

First time using git directly to upload the results of a day of coding to a repository and it is so much more straightforward than the overcomplicated git plugin that I used before.
