[Terry] wished to come up with a bit electronics job for his kids, and also came up with something to keep the spouse happy. It’s an adorable 14-segment like letter, pieced together with some leftover LED screens and a bit of solder.
There isn’t a microcontroller anywhere to be seen in this job – all the illuminated segments are connected to a switch, and aside from a few resistors there isn’t much to this circuit. The simplicity means it’s a fantastic method for [Terry] to get his youngsters included in electronics.
If you’re wondering why [Terry] didn’t throw several Arduinos, shift registers, or LED drivers into the build, consider this: sometimes section screens can be static. the time circuit prop from Back to the Future (but not this contemporary recreation) was wired up in a similar manner, as only a few specific dates needed to be displayed. Either way, we’re believing great on [Terry] for introducing his youngsters to a soldering iron and doing something special for his woman friend.
