At the electronics evening on 25 Nov I demonstrated my version of an ultrasonic levitator.
The original build is here: https://makezine.com/projects/micro-ultrasonic-levitator/
I built the version using an L293D type H-bridge chip and capacitor, rather than the stepper motor driver board.
My goal is to create an open build design using cheap off-the-shelf components, protoboard and a simple laser-cut assembly.
That way, code clubs, STEM clubs and makerspaces could create their own kits for use in electronics classes.
You’ll see that the Arduino function is very simple, and I am hoping I can replace the Arduino with an ATtiny chip. However, I lack the electronics knowledge to even know if this is possible.
I’m hoping someone here could have a quick look at the project and come back with a yes/no/maybe.
If yes or maybe, I’ll continue to explore this at an electronics evening.
