A very small update:
This one is a variable PWM using a 555.
(The 555 Im using is a SOT23 smd fix in the middle, that black square)
But this is a second circuit. A clone if you like.
Because I build another one a couple of weeks ago and install it and run it for a device I make but is on hold at the moment for some other components to arrive for its upgrade.
I hope is clear enough...I tend to give too many details...
This is the exact same circuit that I am making from scratch (again) but the difference is it will be a portable and testing circuit, and not a fixed one as in the example.
I dont really have to make it but it was in plan so I will make it these days. I started it last night and now its pads are finished.
Ive also thought on other 2 sources of test oscilators.
An astable flip flop that I already have in stock for a long time, made from smd components. Very cute and small and I almost completely forget it.
And a voltage divider hooked up to mains for a nice 50Hz input oscillations with 1:100 ratio. Nice eh?
So in total I will have 3 [test] sources of oscilations.
Why? because I mentioned, I will have to test the D Flip-Flops I will make. Thats why. Aaaaah, right?
Stay tuned.
