And in case anyone doesn't know, we received a box of PIR sensors as a donation last week -- about 900 of these cute little boards. David, the donor, sent me the documentation on them. I'm not sure where to post it so that everyone can see it.<BR>

<BR>
But anyway, the box is upstairs, in the electronics lab area. Feel free to grab as many as you like!<BR>
