I stumbled across these PCBs in a thread on the muffwiggler forum (I know, stupid name!) and it occurred to me that some dedicated LFOs could be handy – this was another thing that was tying up my Maths.
I contacted the guy who’d made them and he had some left, so I grabbed a couple off him. He actually ended up sending me 3 of them as they postage was less than he thought. They’re based on a Thomas Henry design.
I built two of them and found, through the same forum thread, a guy called Julian “The Beast”, who could make an aluminium panel for a dual module.
Really happy with the result. They’re super simple free running triangle/square LFOs which I’m sure will come in useful.
