Good news! I just found a discarded VCR with an LED display. That means it’s time to salvage the display and make a project out of it. There is lots of info out there on standard 7-segment displays, but appliance and electronics displays are custom, and this one actually turns out to be 10-segment with non-numerical segments. So it will be an exercise in figuring out how a non-standard display works. In this Instructable I will go over my process for hacking a display like this.
