Juansolos Leslish
« on: July 16, 2014, 04:21:44 PM »
I've been looking for a schematic for the Leslish since I have a Trivibe board waiting for a project and I want to build something similiar. That was just a badass sound coming from the effect he built.

Anyone know?

That's a blast from the past. Yeah that's the schem. It doesn't need the trimmers at the end as it's unity when dimed anyhow.

Here's the vero layout:

That vero is a little confusing as its got 2 circuits on it.

There's the splitter/mixing circuit from my schematic, and the LED/LDR ramping circuit on the top 5 rows.
Transistor is a 2n3904.  The LDRs replace the 820k resistors on the trivibe boards,  the speed pot is a dual gang 500kb, wired to each trivibe board.

We messed with the relative speeds/depths of the two Tri-Vibes IIRC to get them more leslish (Hi freq 'spinning' faster than low). Cleggy will remember how. I can't remember yesterday...*

They confiscated everything, even the stuff we didn't steal!

I think the low frequency trivibe has a 18k resistor on the speed pot, 12k on the high frequency.
