I inverted the trans with 5V to "C" and res on "E" to GND, and tapped the wave off the "E" and it fixed the invert. Unfortunately coming off the trans it always produces a smaller Vmax compared to pin 3 on the 555. I'll have more of a play when I get in the mood.
This is pretty close to final, but using edc's osc circuit mod-ed by me. If I can get a simpler more reliable osc circuit I will swap it out.
You will have to "save" it to zoom in.
