I’ve been building stuff for my own modular format on and off for a while, but recently started experimenting with building a solar powered system. This system is exclusively passive or solar powered modules. I’m currently working on a sequencer and a stand alone power module using super capacitors, so that I can build modules to use solar power or DC.
It’s really helping me learn more about DC, power storage, forward voltage drops, capacitors and a ton of other stuff.
The current version includes;
AM Radio
LPG
4093 Cascaded Oscillator
Clock Module with Clocks, Dividers and up to 10 steps trigger sequencer
6 x Square Wave Oscillator Bank
