Nearly every type of retro indicator technology, from Nixie tubes to flipdots, is featured on these pages in the form of artwork and decorations.It’s nice to see something that hasn’t appeared much over the years, especially one that’s in the hands of our colleagues. [Voja Antonic]He took a number of moving coil panel meters and hooked them up to a microcontroller board triggered by a PIR sensor. The measurements are usually random, but if you get too close to it, all those hands will start to move, giving you a very different view of your electronic wall display.
He didn’t give us the details of the control circuit he used, but in some ways it’s of little importance. Any Hackaday reader who knows both ends of a soldering iron should be able to generate a small DC current from a DAC to drive a meter. Also.
in the meantime [Voja] has produced so many interesting projects over the years. Especially the 2022 Superconference badge is important. This is one from a few years ago.
