Projects & Details

Voltage Regulator

We're hoping to develop a voltage and current regulating power peripheral that connects directly to the power connector on the XO and allows different off the grid power options, whether they may be solar, human, animal, wind or some other renewable energy source, to the XO without damaging the laptop.

  • Develop basic voltage regulator that limits voltage and current to XO
  • Redesign voltage regulator to produce variable outputs
  • Redesign version 2 of regular to all it to charge multiple XOs
  • Possible mechanical design of voltage regulator housing (need to evaluate later)
  • Thermal analysis of regulator (need to evaluate later)

Bicycle Powered Generator

  • Review of literature
  • Development of bicycle powered generator design
  • Building generator

Power Deployment Guide

  • Summarize wiki information and commentary on OLPC mailing lists related to power
  • Put information in easy-to-read guide on power deployment options
  • Make guide widely available

Solar Setup Testing

  • Develop testing methodologies for evaluating a XO solar setup
  • Testing solar setup & publish findings

Thermoelectric Power Generation

  • Explore potential for using thermoelectrics for powering XOs
