Mike's Electric Stuff

www.electricstuff.co.uk

Each of the three main sections has a 'tour' facility for easier navigation through the pages - clicking on the small icons at the corners of each page will move to the next or previous page in that section.

Upcoming public demos, events etc. I'll be participating in
None at present.
I can often be found lurking or presenting at Dorkbotlondon meetings.

Check my Youtube channel - new stuff is most likely to appear here at the moment so subscribe!
