Building your own stompbox / Re: Aion Cerulean (Bluesbreaker/Morning Glory) Kit - No clipping

Looks like it will be worth it to contact Aion, they are helpful

Else, you can check the PCB to make sure it successfully follows the schematic

Building your own stompbox / Re: jFET DOUBLER (redux) ... with full set of training wheels

Good to see you're actually tinkering, not only casting aspersions. I notice you can't quite stop criticizing, though. You need to work on that.

There are several ways to run this thing. The point is, however, to bring up the native nonlinearities of the JFET, not the clipping behaviour. Nor any attempt to fake a full waved rectifier. To that end, you want to keep the JFET in the square-law region, not overdriving it. The phase inverter and opposing JFETs are intended for this purpose.

I suppose I should start sifting through your stuff, looking for "mistakes" I would correct. That would be fun, wouldn't it?
Shall we?
Er, I mean, do you need any help with your stuff? Maybe I can offer some technical advice.  :)

I've seen a different implementation of a vertical counter by Scott Dattalo. Unfortunately the website where he described it no longer exists. Rather than using a byte per reading, like RG suggests, it uses bits like a standard binary counter. So you can count to four with only two bytes vertically.
I've used that variant before as well. It's a very clever idea - and Scott's page is what got me started on the idea. The logic operations between each horizontal stage are open to modification. I used it a byte wide, eight inputs wide, and two stages tall, binary encoded, and added masking and so on. I deliberately skipped the byte-wide logic operations for computing add and carry so that the operation would be clearer. As you say, all thanks to Scott for explaining it to me.

I just made a DOD fx91 overdrive :D (this thread title has no sense anymore)

Not quite a beginner, another 4+1, 2, 3, 4... pedals  :icon_lol:

As for the problem, do what antonis suggested.

Guys i think we have a world record: banzai sent me the wrong box (125B instead of 1590B) and musikding sent me an incomplete order as deliver to complete another incomplete order.
This means ALL the orders i did had mistakes or were missing something. I think it's crazy :D Luckily i do't do it as a job

Building your own stompbox / Re: Diode I/V comparison graph
« Last post by garcho on Yesterday at 06:05:22 PM »
that's how you can hack a diode as a variable resistor, in a really quick and dirty kind of way, say for an active filter

Debouncing in software is one of those things that you end up coding over and over again. It's always the same thing (checking a stream of bits), but different enough (read operation, number of bits, multiplexing, etc.) that you can't have a standard library.

I can't thank you guys enough for the help.

I really appreciate it and I'm looking forward to getting back at it now that I've woken up haha!

was the voltage at the non inverting side of the opamp actually clean?? or was it contaminated? how about a big capacitor to ground from there?

Very exciting. Is it so sensitive that we'll need multi-turn trim-pots?
no, the volume of the signal gets balanced, not the bias point, there is no DC on the pots. and the rest is all self biasing
