Flip Fluid on Flip Dots

He mentions in the video and in the article Breakfast Studio and I happened to watch a video of one of their panels on an unrelated YouTube channel. I've skipped ahead to when the video has the panel. (there is also a cool egg just before that point in the video) it's only about 5 seconds.

It's really cool to see some innovation in flip-dots and their colours, seems really quiet too. Shame these things cost an arm and leg and are massive, something like this in your house would look great at like 1/5th scale.

I have recently resurrected one from an old bus — https://www.bobek.cz/buse/

The dots are so delicate, with tiny magnet wires and soft plastic that can melt, that it has to be done very carefully. Even with the very best desoldering equipment it would take forever.

Put a hot air gun on the back of the board, and they'll either just drop out or do so with a small poke of the pins.

Instead of using capacitors ... why not use a negative supply rail? Then you can switch the direction of the current in a coil using only two transistors.

Summary: Mitxela designed and built circuit board to drive old flip dot displays - boards donated to Sam from Look Mum No Computer and iterating on an approach from Mike at Mike's Electric Stuff. He ended up with 1m^2 of flip dots with an interactive high frame rate fluid simulation.

I can only express my deep respect and recognition for an amazing execution, craftsmanship and video while creating some thing fun and entertaining.
