Very nice, way to go! Welcome to the addiction...

That's a amazing...I wonder how many of those they made and how that goes with consistency using carbon comps in there.
In any case sweet stuff.
Great to see on that page link also Pickdroppers and Leevibe gutshots as well!

Awesome, I bet he was thrilled and over the moon!

Very cool and neat graphics! Certainly some fairy dust and rainbows going on there ;). Thanks for the demo too, great to hear!

That can't be your FIRST build. That looks like your 20th build. Very clean solder joints, especially on switches which can easily have gaps since the holes are large. Clever placement of the LED.
That looks great.
What he said.... Noice!

I donít need any of the 150 pedals Iíve built, but man do I want them.

Amazeballs and you certainly have got the etching nailed! 8)

Sweetyness and that etch came out great! Very tidy! 8)

Excellent and sweet looks to boot! Bit of a vintage T-shirt vibe look.

Lovely and great to see he steps, thanks for sharing! Apart from the spiffin art look how do you ike the sound of this and what transistor did you end up sticking in there (hfe/leakage like Rangemaster I guess?).

Hope everyone is keeping safe and well there and yes Smallbear is just indispensable... big shout out to Steve and crew!

VFE Projects / Re: power filtering in Vfe two 100n caps parrallel?

The small power filtering caps are placed directly next to the individual ICs (usually as close to the ICs power pin as possible). It's not totally necessary but it is good practice for filtering/noise. Actually, on many of the dual supply effects he puts two: one for positive and one for negative supply of each IC.
Awesome, thanks for the quick illumination!

VFE Projects / power filtering in Vfe two 100n caps parrallel?
« on: May 20, 2020, 04:48:03 PM »
I have seen this now in several schematics of Vfe designs, having two 100n caps parralel to ground for power filtering.
What's the point of that, what benefit would that have for example in comparison to put a single 220n cap to ground there?
I'm sure Peter was thinking of something there... he's that clever sorta guy...

Thanks for finding those gems... a lot to learn and gaze at schematics now...! Cheers

However, one trick I employ now is to use a low-pass filter + series resistor in front of the LED. This simple circuit both allows the player to tweak the brightness of the LED via an internal trimpot, but it also makes the LED ramp on/off. This quick ramp softens the abrupt current strain on the power supply, and in many cases, helps reduce the amount of pop produced by the circuit.

Now that sounds really interesting... how would this low pass filter be implemented, I can quite see it on the snippet of schematic from MB build doc... would need another cap somewhere wouldn't it?
