My major Fast Stacker revision (2.0) is fully operational - as a prototype for now. Based on a much faster microcontroller (ESP8266), better motor driver and display. Capable of smaller steps (0.6 um) and faster speed (at least 10 mm/s). Lots of free memory for future software improvements.
My workshops were a shortened version of my "Arduino For Total Newibies", with an ESP8266 board and environmental sensors. We all had fun and learned a lot. I went to Brno, Czech Republic for 4 days to give 4 workshops at Maker Faire Brno -- two workshops for teaching teachers, and two workshops for anyone at the Faire.

The disconnector and autorestart perf board.
My Raspberry Pi computers have an ESP8266-based UPS that can restart and power-off the RPi. This board disconnects the wall power UPS input so that the UPS and RPi are completely isolated from external power. A lightning detection system supplies "Strike Probabilty" data via a TCP socket so that the RPi can tell the UPS to shutdown everything.
There is an ATTiny45 on this board that is powered up when the main relay is de-energized via a n.c. contact and runs from 2xAA batteries in micropower mode. After an hour, the Tiny turns on the UPS which powers up the client RPi and turns off the Tiny.
