#555 Beat Bot
A silly little @MaywaDenki-inspired critter using multiple 555 timers and a CD4017 to play and dance to a tune.
Here’s a quick demo..
Notes
Project #555 had to feature the 555 timer of course. I was inspired by the crazy creations of @MaywaDenki.
I borrowed a 555 timer music box idea for the basic sequencer:
- a 555 timer provides the clock pulse
- driving a CD4017 wich acts as the sequencer
- with another 555 timer providing the modulated audio output
- a pushbutton provides a trigger to short-circuit the sequence (although in the build for the demo clip I realised I’d used a normally-closed pushbutton by mistake, so the effect is inverted)
The synchonized hand-waving uses another monostable 555 timer to pulse a solenoid.
Construction
Testing the basic tone sequencer on a breadboard:
After circuit testing complete, I renderd the circuit on some protoboard for installation:
