This is another homemade digital clock. I designed it with Fusion 360 and printed it on my 3D printer. It took many hours of printing. I've also created a new Android App that you can use to control it (more info on GitHub). I've used the same controller board that I've made for my other digital clock. At daylight it's not very bright, results are best at evening.
