This is what the PWM project turned into. It's basically the same circuit, put in one of the cool new trapezoid boxes, partly because the standard 1590B MXR sized boxes were too small for the circuit, and I didn't want to have to use the much bigger 1590BB. This is the perfect size. Plus, as I've already said, it looks cool!
I'm not sure that I've found a practical use for this yet, but it's easily the most fun I've had with a stomp box since I got the Fuzz Probe (something to do with the fuzz?).
The knobs are gonna change, but these were the only ones I had, hence the odd one. It's also going to get a screen print of a weasel on it that's being designed by a friend, updates to come.
This is the post that I wanted to put up last night, but, due to Youtube being useless, it's had to wait until today.
Anyway, having spent a while checking out every schematic on Tim Escobedo's site, I decided to have a go at messing around with the PWM, which turned out to be masses of fun. At the moment, it has an envelope which controls both the speed and depth of a tremolo simultaneously. The tremolo, in turn, is controlling the pulse width.
Confused? so am I, here's a video of what I've got so far:
So, having read a lot about the LM386 (op-amp) and PT2399 (delay chip), I decided to get a few to mess around with. After getting them both in the post today, I got out the breadboard and started to mess around with the LM386, hoping to come up with something interesting. This might have happened, if I hadn't busted both of them by plugging in the power supply with the wrong voltage... not an expensive mistake, but I was having fun!
Anyway, with no 386, I moved on to the 2399, and built the LoFi delay, which, as it turns out, doesn't work very well with guitar (should have heeded the warning). Anyway, one more idea down the drain, on to the next! I'd seen the Noise Ensemble on DIY Stomp Boxes a while ago, so, still hungry for something that would give me some interesting noise, I gave it a go, and it sounds awesome, I've got it as 'stock' at the moment, but am going to mess around with it over the next few days, I'll put up some sound clips when I've got something I like.
