Good day to all!


Engaged in here at your leisure the design of the Braille display. Nothing better not figured out how to make a movable part in the bistable solenoids, even a small move will make the rocker arms. But sorry, can't find solenoide less than 20mm in diameter, and ideally should be of the order of 5mm. no one came across (maybe somewhere they can desoldering...)?


or maybe there are other ideas on implementation of the moving part?


Sincerely,

Ilya

I have never met never even directories. I propose to improvise is to use a polarized (or normal) relay. They come in different sizes.

You can try to adapt vibrometric from mobile phones, they are small enough.

Here's a thought. If do use micro-motors. And the end position to control the current.
