Step 3Install it...
Install the circuit board and the 9v battery in the hobby box. Line up the photocell at the hole and hot glue everything in place. Also, attach the siren and run the wiring inside the box. Finish your solder connections with the siren.

I am new to this stuff, so i was wondering if that long blue thing is the resistor.

I have built a circuit similar to this. I found the plans at radio shack. I bought them at the store, and wired it up without too much difficulty. made 4 of them it was fun. today they dont get used though geez.

Unfortunately I don't know where that book is anymore it may in the closet in a box or who knows its been a long time. Like I said, radio shack has it its a small paper book.

bgineat: Can someone with hardly little knowledge on how to make a circuit thing as shown be able to do it? Did the one you found at radio shack one work for this?

Well, you need to take note of the direction the transistor gets soldered in. I made my own little board by drilling tiny holes in a piece of brown hardboard 1/8 inch thick. The book shows how to do it. Its was cheap the book I paid must have been 8 years ago 2 bucks for it. Just a small paper book. not too many parts are in the circuit. a potentiometer, relay, resistor, photocell, transistor, Yes it worked using a 5mw laser diode pointer and the parts are a little different.
