My latest project, the robotic skull, is getting complicated. Right now there is a quad-core processor in the JeVois smart vision sensor, a quad-core chip in the Raspberry Pi and a micro-controller in the Arduino. We’ll probably add at least another ESP8266 to the mix.

One of the prime reasons I’m developing this project is a testbed for exploring physical computing ideas. Being able to demonstrate concepts with a self-contained device makes a lot of sense and using a Raspberry Pi as the central “brain” works great. Just hook up an HDMI monitor or projector, plug in a wireless keyboard/mouse-pad and we’re good to go. In addition to “showing” how the various physical computing concepts and subsystems work, I can also put up slides using LibreOffice, if needed, right from the skull.
