What to do with Blue Balls

Here are all of the parts that you need.

Click on the schematic (and all other pictures) to enlarge it. Sorry for the hand drawn schematic 🙂 Depending on the resistance of the photo-cell that is used the 100K ohm resistor may need to be larger or smaller. If the resistance is not correct the circuit may not function properly. For example if it is light it may stay on or if it is dark if may stay off. To find the best value you could use a potentiometer to vary the resistance until the best value is found. Elmetal had a great idea to add an On/Off/Auto switch to the design, here is a schematic to do that.
All of the parts found their way onto the breadboard for some testing to make sure the design works before soldering it together.

This bottle is itching to be hacked!
