[Noisebridge-discuss] Ready to restart Arduino Thursdays at Noisebridge

I used to start at 6:30 which I think worked pretty well. Late enough to
miss the 5PM rush hour, late enough for parking meters to be free, early
enough to get to bed at a reasonable time.
6:30-7 PM basic installation and blinking LED for beginers
7-9 PM playgroup
Anyone want to take this over for a couple of months since I'll be busy
on Thursdays?
