Depth Charge Enveloped Tremolo

[Kipper4]

Heres my gift to all the forumites who have inspired and helped me down the years.
It's not perfect but it's working well on the breadboard.

I present The Depth Charge Tremolo
The depth of tremolo is controlled by the envelope detector.
The harder you strum the less tremolo you get.

Crikey, Rich - do you ever sleep??

Yeah, in an envelope...

Nice work. You've pared that circuit down to just the essentials too. That's pretty simple for what it does.

Do I see a trilion totally confused guitar players stompbing on their effects..?? 

[EBK]

I like this idea.  Have you tried a vactrol for the speed as well?

[Kipper4]

Sure have. If anyone's interested I could share.

[Kipper4]

I was thinking also of doing a layman guide to enveloping different parameters.
Wasn't sure again if anyone's interested much.

very nice. can we hear it? (not from here, obvs.)

..... totally confused guitar players .....

ha ha ha.

also: stompbing.

Untested speed mod Depth Charge. Untested because the Resistor in parallel with the ldr is undetermined.
It wouldnt take long on the breadboard to sort it out. Try 100k as a starting point.




I'll try to oblige Duck with my usual riffs in a ghetto lab demo. No oscars needed of course.

Marc Sleep is for the weak.

Smoke me one, it'll soon be morning.

Pfft! Since when did that even stop us?!

Get on with it already! Your fans are beating on the door!

Hi Kipper,

Where does your "Vr" come from? Is this bit missing?

8-)

[Kipper4]

Hi. It comes from R11 R12 and goes to both inputs of IC1A-B
The lfo has its own VCC/2.
Make sense now?

[antonis]

Make sense now?

Same as before.. 

We know you're a lazy sleeper but you could try to label differently +9V from Battery and +9V after PSU filtering..
(after all, there is a Schottky and a 100R resistor between them, so they can't be of same voltage value except in case of zero current pass..) 

P.S.
:beer: :beer: :beer:

Labelling of supplies matters if you intend to make a pcb from the scheme - it will route all +9v nodes in common connection.

If Eagle, I use a "Wirepad" component to denote off-board connection. You can name those whatever you like.

I was going to say that on version 5 (the first) and version 6, C5 is in the wrong spot, but now I see you have a new version 5 with it correct, so I'll stay schtumm.

[antonis]

Another reason to follow Rich's threads counterclockwise... 

(old verison - new version - newer version - revised old version - grrrrrr... )

[Kipper4]

Oi I get there in the end.......
