    Anyone here from Toronto? Been to Active Surplus in the past 20 years? They've been selling these motion detector kits since as long as I can remember. My dad bought me one 11 years ago for my very first electronics project when I was 13 years old. THAT one came in a box, with instructions.

    So I stepped into AS the other day, and they're still selling them! But no box, no instructions, and I cannot for the life of me remember which pads are for what.

    I think it only needs 4 connections; V+, V-, and two lines for a speaker. It does all the rest using the included 5 capacitors, and the motion detection is done using that IC+lens combo on the right there.

    I just thought MAYBE someone here happened to have been to AS, and happened to have bought the same kit, AND just so happens to remember how to build it? :D

    Yeah, I have one of them and I even have some documentation I think... I think it's actually in PDF form.

    I'll try do dig it up later today.

    The chip is a ULN-2232A

    Googling for that gives you some leads, but I suspect the page you want is this one.

    I have 2 files on my server at home, but I can't easily fetch them from here. I'll try to remember when I'm back at home.

    Awesome, that will work just fine, thank you so much!

    I wonder what the product that these PCBs were designed for actually looks like. Especially what that set of circular traces on the bottom is.
