The 9 Volt Synth Project

After a long hiatus, I think it’s time to get back on with this blog. I started it back in 2013 because I wanted to detail the Korg Lambda – a synth nobody else seemed to have documented fully. Over time I added some mods to the Moog Werkstatt, a few miscellaneous pieces, and added the beginnings of a DIY page. Then I tailed off. Life intervened. The day job took over, I started developing a large modular synth, and I was taking on repairs for friends. The blog was still on my list of things to keep going, but how?

A comment from some time ago popped up in my brain – someone had commented on the general lack of 9 volt synth circuits, little things that could be run off battery power or guitar pedal style DC adapters.

Well here we are 🙂

I’ll be posting a series of circuits, designed from scratch, by me, to run off a 9v supply. Over time these will add up to a complete synth – oscillators, noise, filter, amplifier, LFO, envelope – all the ingredients for a modest but expandable analogue synth. I’ll be building each circuit with full documentation and (if I can manage to get my head round it) a video demo of each in turn. I’ll aim to explain as much of its working as I can sensibly put on a blog page, and offer hints for your own experimentation.

This is going to take a while, because I have to fit it inbetween the stuff that pays the bills. But I’ll post updates on Twitter and Instagram (links somewhere on this site) and do my best to respond to enquiries posted here too.

If you’re reading this, thank you. It means a lot that this blog has been, and remains, as popular as it has. I hope to see you all here for a long time yet!

All the best,

Nathan
