I have a school project and part of the requirement is to build a circuit that uses light and simple parallel and series wiring to show weight progression. The weight progression being shown is weight being added to a balsa wood tower. What I'm planning on doing is building a box with 8 bars cut in it where I will attach christmas lights in the slots in between. I'm thinking about using about 100 christmas lights. I found they run brightly on about 1.1 volts. I think I'm going to have 12 lights per bar. To turn these bars on and off I have 8 switches so I'll have a separate box in which the switches would be held. I'm wondering how I would go about powering each bar. I know I have to step down the power but I'm unsure about how to go about this. Someone told me a single PC power supply would work. I have a lot of simple electronics supplies like transformers and resistors. Oh and capacitors but I don't know how useful those are. Any suggestions? I'm in America so my outlet is 110v.
