Wearables Workshop Development and Conduction: my seminar at the LMU
During the last week of February I was teaching a seminar on wearable technology and education for the third time in a row. This course was a collaboration with Dr. Karin Guminski, Michael Dietrich from SPIELkultur and Cornelia Schmid-Heizer from Nymphenburger Schulen, and Simone Damm was assisting us this year.

One of the challenges this year was having the double amount of students on the course: 24 instead of 12... And another trouble was that I had a flu and completely lost my voice on the second day. Which is not the most convenient thing for a teacher. On the last day of the course, my co-teachers had to act as my voice and read or say out loud what I was meaning to tell everyone in the classroom. Human amplifiers :)
ATTiny85, as I wanted them work with sound. ATTinys are little micro-controllers, which only cost 1,50€ in the eHaJo-shop! A great price for a computer. Similar to an arduino, you can address different pins through code, and attach sensors and actuators to them. Here is what we were doing during the first one and a half days:
STEP1: I've used Arduino Uno to programme the ATTinys (thanks to Hannah Perner-Wilson for a fantastic tutorial). I've used the following code for the Super Mario tune, and this one for the Star Wars tune, and adjusted both slightly.
STEP2: I've made the following swatch to demonstrate the circuit. I intentionally left it as basic as possible, as I didn't want to influence the students' future designs in any way. The circuit uses a 3V battery as a power source, the ATTiny chip soldered onto a piece of stripboard to control everything, a piezo for the buzzing audio output and a standard LED for the light, and two popper switches to open the circuit.
