Intro: Simple Electronic Light Sensor

I may post an instructable for this.
This is a simple electronics project I set myself. I used vacuum formed plastic to make the case. To make it I simply made a solid wooden box and put it in a machine which melts plastic over the wooden model and 'sucks' it on tight. Once set you get a nice result.
To make the battery holder (although it's a little temperamental) I simply bent a piece of plastic using a hot wire to make a "||" shape the same width as the battery.
Lastly the circuit was made using copper clad board. I laid out my circuit plan on the board using strips of vinyl and then put the whole thing in a bucket full of etching liquid (can't remember the exact name!) which dissolved all the copper apart from what was under the vinyl which left a nice, neat circuit board! All that was left to do was drill holes for the components, a hole for the switch, and 2 holes for the LDR (light dependant resistor, A.K.A light sensor). I drilled a hole in the base to make it easier to remove.

If you head to the original YouTube video the description has a good use for this device!

    OK but you will need a basic grasp of how to solder before you start this.

    Well I have a soldering iron in my tutor room in school, and we are allowed to use that after school, but no computer in that room, so Id probably have to take my laptop in :)

    BUT NOW YOU'RE A PRO YOU CAN PRINT THE PDF FILE!
    That's if I ever post. Which I doubt.

    Oh ok I don't have circuit wizard but you can design circuits with PCB wizard but it's not as good as a proper circuit make like livewire

    I use "Livewire" I think PCB wizard is pretty much the same though.

    Okay you're not the first to ask me so I'll put a few diagrams on the comment section in a bit

    Not to mention some simple mistakes in grammar like long sentences and some meadering ones.
