The clock consists of  4 modules of digits paired in two units. Each pair is powered by  a 20mm geared stepper motor. Each pair has one module driven by the stepper motor and the second module is moved by a carryover mechanism.  Both the units are controlled by a control board in the base containing a atmega8 running in the arduino ecosystem.

Out of pure boredom I’ve made a programa with python and mediapipe to detect how open your fingers are and translate it into degrees some servos have to turn, then, this vector is sent to an arduino which moves each servo as needed, here is an example.

I think it has came up pretty well, and just wanted to show it.

(I’ve posted a update with the flair project discussion)

Ik ben vorige woensdag begonnen met leren over arduino’s; alleen chatgpt verpest mijn code (duhhh). Hoe dan ook, ik kocht een ELRO-monitor bij een kringloopwinkel en blijkbaar heeft die alleen video-uitgang, dus ik heb dat beest opengetrokken en ben begonnen met allerlei hypotheses te testen via de BIG gpt . Hoe dan ook, ik heb een manier gevonden om ervoor te zorgen dat het scherm gewoon toont wat ik wil, en ik heb hem “hello world” laten zeggen. Ik ben zó blij en trots op dit project. Ik dacht dat jullie misschien wel een leuk verhaal als dit zouden waarderen. :)

Project mostly detailed here by someone else: https://www.instructables.com/Making-an-Acoustic-Levitator-or-Ultrasonic-Levitat/

I modified the code for use with an R4 and an L298N motor driver.

Here’s the modified .ino file for the R4: https://pastebin.com/3FaweFdV

What do you think of my Arduino Pro Mini-powered flip clock? It’s still a prototype, so the 3D-printed case is a bit scuffed, but it works! I also added timer and stopwatch modes. Let me know if you have any ideas for extra features!

Got bored and finally did a project I was pushing off for probably a decade. Its a "breadboard" arduino but on a veroboard. Not sure what is want to use for the power connections yet.
