Hi Everyone,
Thanks for the responses - it's a bit of a rainy public holiday here, so I decided to bang together project similar to what
Ms Mad Lemon solution implemented with her single input version the only difference is instead of using two electrolytic caps back to back, I ended up using single unipolar electros.
With my very quick testing, it seems to work alright and was a fairly fun/simple build. I documented my build on
github for those that are interested.
Thanks in particular to Lineof7s, a low cost option is certainly worth trying first and seems like it is good enough for me. However krashan - that KA71 does look like a nice thing, shame its no longer available!
no9, thanks for going the extra mile to explain what you were proposing hopefully someone else can take inspiration from that.
