Build with what you have

Since I keep everything, I really should make something out of all the "good junk" I've collected. This might take a bit of time as it is not a first priority but it would be nice to make. I do go through a bunch of recordable CD's and DVD's so I purchase them in bulk 100 at a time. They come on a spindle with blank protection discs at either end. Some are clear and some are opaque black.



Two things that I would like to build is a day/hour readout for my control desk as well as an automatic shooting star projector.
