[dorkbotpdx-blabber] counting bicycles

[Michael Bunsen]

I like the piezo idea and would love to help with this project. Are
you interested in making a display to show the bicycle count publicly
(like large LED numbers), or something just for the staff?

Come by the meeting tonight if you're interested: 7pm at Backspace (NW
5th & Couch)
