Here is another project I like – a DIY infrared camera. The part list reads like something you took from the trash bin – I mean this as a compliment.  Read for yourself:

• webcam
• camcorder – working or not, you’ll just use the lens assembly
• infrared LEDs, or IR illuminator board kit
• computer power supply case, or any other type project box
• power supply, i used a 12v (from printer) and a 6v (from cell phone charger)
• misc switches
• wire, solder, rubberband
• nuts, bolts, scrap metal (for making/mounting brackets)
• hot glue, blank cds (the clear plastic ones)
• IR filter- make out of 35mm negatives, find the black part at the beginning of the strip
• patience
