This is a project i was working on for the last couple of weeks. The progress was slow but i managed to finish it.


The CD-ROM stores up to 20bytes and has to be written manually by placing diamond or coal (material doesn't matter as long as it doesn't conduct) in the pits on the surface, while the CD-R can store 10bytes and can be written automatically (but only once). If you decide to change disks please make sure that the blue or red lines are alingned.
Please give feedback so i can improve the design and remember its only a prototype so there will be bugs.

I'm not sure because brown aray doesnt pass on spark so it will be quite hard to detect.
