David writes “I noticed the powered paint can project that was posted and thought I’d submit a similar thing. Lalya Gaye, myself, and others in Gothenburg, Sweden have been running DIY electronics outreach workshops that cost participants only for the parts. This workshop was to create devices called Portable Art Noise Things (PANTs), which were self-powered speakers amplifying a contact mic. We love contact mics in performance and wanted to be able to take them on the road. Participants were encouraged to bring their own containers to personalise, it also created a huge variation in the sounds that these things created.” Link.
