Kiezfest Lichtenberg, Berlin / September 2011
Recently, the organizers of a street fest in my neighborhood asked me if I want to contribute something. As I really like my area and the people living there, I certainly wanted to offer a little diy electronics workshop! So I packed the more important half of my workshop onto my little pick-up truck and drove around the park to the party location.
My ‘car’ (a Piaggio ape from 1979) is loud, it smells a lot, it is shaky and slow (the motor has only 3.5 HP), but a hell of fun to drive. What makes it really useful is that it can carry loads up to 200kg. That’s enough for bringing a table, some chairs, tools, working light and material.
Soldering started right after the setup of my workshop desk.
The visitors were building different things: Little vibration motor robotos, oscillators for creating sound and Drawdios.
Actually, building the Drawdios and playing with them excited everyone.
Even when it became dark already, my table didn’t get empty. My neighbor Günter (on the left side) helped me throughout the workshop to show the visitors how to solder and how to read circuit drawings.
Here’s one of the Drawdios.
We used Jay Silvers original circuit based on the NE555. That’s a quite simple circuit which is easy to build.
You can find all those photos in a higher resolution here.
And here’s a video of the original Drawdio:
