when you put on breadboard the same circuit over and over, it’s time to think that soldering few parts and a header could help.
As I end up using the same LFO for all my swirling projects, I decided to put it in solder and, like all those new arduino stuff, install a header to be able to use it on a breadboard.
It’s quick and dirty but useable and will avoid, or reduce at least, the dodgy mess that a breadboard can produce.
The header provides several outputs (square, triangle and a variable amplitude triangle). It offers the usual speed control and depth (for the viariable triangle ouput).
