A complete Linux computer in a pair of glasses

Summary

Hackaday presents a head-mounted Linux computer that combines Gumstix, display, motion sensors, radio and battery without an external computer. The system weighed about six ounces. The parts cost less than 1,000 US dollars.

Ideas

  • A Gumstix Overo Fire runs Linux right on the head.
  • The Vuzix display contains an accelerometer and a compass.
  • A custom converter board generates the video signal.
  • Wi-Fi makes the glasses usable without a data cable.

Insights

  • Wearable computers require weight, heat and energy to be optimised together.
  • Custom adapters close gaps between incompatible modules.
  • Full integration can reveal comfort problems more than functional problems.

Facts

  • The processor was based on TI OMAP.

Recommendations

  • Place lithium batteries mechanically protected and with temperature monitoring.
  • Measure radio and heat exposure before longer use.
