This instructable is a modified version of the various LED Sun Jar and Night Light instructables on this site. This is my first instructable posted and is really just a proof of concept at the moment. Revision plans have already started. This particular version is switchable between 1, 2 or 3 lights. The parts list, as I made it, is as follows: 1 x Red 10mm clear LED ($0.90 AUD) 1 x Green 10mm clear LED ($2.70 AUD) 1 x Blue 10mm clear LED ($2.60 AUD) 1 x 180 ohm resistor ($0.38 AUD 8pack) 1 x 240 ohm resistor ($0.38 AUD 8pack) 1 x 150 ohm resistor ($0.38 AUD 8pack) 2 x diodes ($0.38 AUD 4pack) 1 x 9v battery ($5.65 AUD) 1 x 9v battery snap ($0.29 AUD) 1 x single pole sealed rotary switch (set to 4 position) ($2.95) 1 x Clear glass jar (I used an old coffee jar) 1 x Empty aluminium can Broken glass (How much is needed will depend on the size of he jar) 0.12mm wire (To connect everything. USE A LIGHT INSULATION COLOUR) Circuit diagram below is what I drew up after a brief discussion with the guys at work. (Thanks also to the guys at Jaycar for giving me a crash course in resistors)
