[ELECTRON] Proposed new club + Arduino meet up

Fri Oct 28 20:43:26 UTC 2011

Thank you to everyone who attended our meeting.

Blair has been making impressive work on the reprap. It is now printing
recognisable objects. We made a lot of progress on finding the materials for
the community reprap.

One thing that I thought after the meeting is would there be interest in
collecting some tutorial introduction to the arduino? I am  thinking some
prints with circuit diagrams and code.

Thank

Kieran
