wind tunnel controller v2

We’ve got another 24 workshops coming up over the next to weeks for SAUCE, and so we’ve taken the opportunity to upgrade the wind tunnel.

  • New motor with more rugged turbine fitting,
  • upgraded RPM and current sensing,
  • new PLC for fan control,
  • software updated for better RPM measurement and serial communications.

I’ve also posted the software for the PC and the microcontroller on my github pages. Thanks to Power Drive Service for rapid delivery of the new PLC!

Personal Wind Power

I’ve been commissioned by the Calthorpe project to build a wind powered phone charging station. The majority or the build will be done on site with a group of young people, over 3 days.

The idea is to do some hands on renewables learning that results in something that’s useful to the garden’s visitors.

For those interested, I’ve posted some of the technical details on openrenewables.org.uk.
