[Vanhackspace] Reminder, Meeting Tomorrow

[dan anderson]

A bit late, but w.r.t. arduino audio, one of you was kind enough to
explain how he was flipping an output pin to generate tones, after I
mistakenly guessed that he was using pwm. I came across this today,
and thought whoever that was might be interested:

Have fun tomorrow. If hackability of the lock is an issue, and you
want straight hardware, might I recommend abloys? I've never known
anyone who can reliably pick one, even with the tool, and if someone's
got a decent cnc machine you don't have to actually pay for Abloy(tm)
keys past the first that comes with the cylinder.

Actually, if anyone has access to a decent cnc and is willing to run
it, let me know. Not that I'm itching to learn g-code (shudder) except
as a means to an end.
