Somebody’s been making off with your stuff, and you don’t have a clue who it is, do you? Here’s your chance to catch them in the act. To complete this How-To you will need: A laser pointer Some Duct tape A few small mirrors A LM741 microchip A 220-ohm resistor A photocell An inexpensive digital camera An extra small screwdriver A wire coat hanger Some thin, insulated wire A printed circuit board A 9 volt battery A 9 volt battery clip Soldering equipment A pair of wire cutters A soap caddy with drainage holes A voltage relay Step 1: Build the circuit Build the circuit. Center the microchip on the circuit board. Pop in the voltage regulator. Connect the battery clip leads to the regulator. Run 2 more leads out from the regulator. Pop in the resistor and the photo cell. Link the chip to the photo cell. Pop in the relay. Link the chip to it as well. Link the other side of the relay to “power.” Step 2: Disassemble camera Disassemble the digital camera so you can access the board connected to the camera’s trigger button. Tip: You may have to remove the camera’s board to get a good solder …

this didn’t really secure anything, i mean he still stole the pen, and why would you go through all this trouble for a pen
Maybe it’s me but, didn’t we only uncover the perpetrator has a hand?
connect the what to the what then cut the what and wire the WHAT?

a laser pointer,
some duct tape,
a few small mirrors,
a circuit board,
a digital camera,
a soap caddy
and a coat hanger
look inconspicuous
thumbs up if you see the middlefinger on 3:51
Why the hell would anybody buy all tht stuff
thats to much damn stuff cheaper if i buy a video camera and have it run all day XD

@cheyennetheguitarist haha.. so true
Okay can we connect them wherever we want
ya like no one is going to notice a camera sitting in a soap container with a bunch of mirrors lying around. lol
Wouldn’t it just be easier to tell us what we DON’T need?
who the hell woul have a soldering iron?
Computer web cams can just do thi with a program..
when i went to buy all this shit i found it would of been less expensive for me to have bought a laser security system
That’s a Breadboard not a PCB
I knew i should’ve took electronics in high school
someone is giving a finger(at 3:50)
