Today Marian and opit made lighting for our donations box: they connected some Neopixel LEDs to a power supply and an Arduino:

Rees came by to solder some pre-amps for a series of public workshops he’s running, Vilius assembled his 3D printed hands-free device, miceuz started to develop a laser maze. We also hooked up an optical encoder to an Arduino – we intend to use it for wind speed measurements. Come to the next one – maybe we’ll be learning to use an oscilloscope.
