@ jonnydavro - about flyback
Attached is a circuit using only one resistor that you might want to try also (it is a Joule thief circuit).
I do not think a flyback will work as well as your simple SEC for wireless stuff because it works at a much lower frequency and therefore less energy is capacitively coupled through a given capacitor value. My flyback was working in the low KHz range. I suspect your simple sec is working in the MHz range. That is a difference of about 1000 in energy coupled through a capacitance.
Hmmmm...... My circuit was converted to a smaller size by the forum software. The result is a bit hard to read. Sorry, I am still learning how to do things here.
