Well, without too much pain, its just about working!Here is how I went about it, which might help you if you want to make one yourself…When you pick a drive to use, make sure it has four conductors going to the motor (“Y configuration”) rather than t… Continue reading →

Just starting this project, which again uses a 2.5″ laptop drive.Last year I made a POV “slot” clock on a HDD platter, inspired by other peoples projects I saw online. Around the same time saw an excellent project on YouTube where someone had made a di… Continue reading →
