Ätz-Station update 2019

We just reinstalled some pumps, tubes and wires.

Measuring Temperature

Also we installed the Gär-Lämpli to measure the temperature

The temperature is display on the LED-ring starting at 25°C on the upper left and then in a circle to 55°C on the upper right. Also color changes according to temperature. if its yellow-orange optimal temperature is reached 45-50°C.

New code can be uploaded through Audio, TinyAudioBoot, 8Bit Mixtape style. See the source here:
