tools i used here were a small screwdriver, a pointy thing and a pair of tweezers.
optional things to play with could include
infra red light source ,this could be a tv remote control or if you want more power you can buy ir leds off bay china for not much and make something good, there are now kits available to make an OK ir light. or you could just use the sun!
infra red filter ,exposed leading end of a negative can work, they can be found in remote controls(plastic cover thing at the end of the remote you point at the telly or whatever)and on the remote controlled thing as well it will be there covering the sensor , and again they are also available on the bay
Step 1: The convertee
any way its a real basic camera ,make things easy avoid auto focusing cameras,
