Not sure how new this one is, but I just noticed it:

Bergfotron VC Delay

VC Analog Delay, PCB for Press n' Peel; uses MN3207, BL3207, or BL3208 BBDs. Small Bear has these ICs for $4.25

Hey! Hold it!

Don't etch it!
try to look for the schematics first.
That's it...
NO SCHEMATICS!

How am i supposed to... well anyway...
It's not new, at least half a year old, i was waiting maybe he uploads the schemo, but no.

Why bother, I can't see any advantage over the ADA Flanger.

This looks awesome!! I've been wanting a DIY VC Analog Delay for a long time. Even though there aren't complete schematics, it looks like all the info you'd need to assemble this boards is there.

Good find, I might have to give this a go (after I've completed the mountain of other SDIY projects I have sitting in my kitchen).

Any ideas on those resistor values? I can see the color bars on the full ones fine, but some of the small (vertically mounted?) ones I'm not sure of.

He says the circuit is based on the schematic from the datasheet.
The datasheet here lists specific values.
Maybe a good starting point.

why not just ask him for the schematic and parts list?
Its worth a shot Wink
