Just wanted to give a heads-up to anyone needing a PIR sensor. Electronic Goldmine has them on sale for $4.99 (normally $14.99) until Monday, 9/ 28/ 14 or until they sell out. Here's a link

Gary Adams did a hack for this but the forum will not allow me to post the link. Do a Google search for "Quorum PIR By Gary Adams" and it should be the first one.
Not sure why the picture in step 1 was changed but here's what it's supposed to be -

That looks like a good price for those! Nice little units. Just a pity they run off a battery, but I bet they could be re-wired to run off another power supply.

Yup, that would be an easy fix.

Yea, that hack that Gary (Otaku) came up with for building a timer triggered by that PIR was very ingenious.

I built two or three of them and they worked great!
