Post new Fatman oscillator
I soldered up the oscillator as tiny as I could. It doesn't work consistently and is hard to debug with all the buried components.

- the LED goes dim when I connect the cv input.
- sometimes it only puts out a high freq wave, about 10khz?

my next project is to build a dual osc with ramp, square, suboctave and triangle if i can get it to work.

any thoughts as to 2 x 555 or 1 x 556?
