Dual state variable filter using PWM I designed a while back, it seems to take me a while to finish stuff these days ;D. The filters can be put in parallel or series and swept with the same or independent envelopes. I was aiming for a kind of mutronics mutator with mutron biphase kind of controls. The series setting is pretty wild!

Wow, you are a madman! That's killer.

I'll try to get one done over the weekend if I can, but it will probably be low quality due to my lack of video skills  ;D

Ah thanks! I had to take a few breaks when I was doing the switching before I completely lost it, it's always the simple stuff that messes me up!

That looks killer! (i hope the joke is not lost in translation - makes total sense in portuguese  ;D)

Which transistors have you used?

The Starship Enterprise called and they want their control panel back?!?  :icon_lol:

Introducing Pawdrive !

What could it be? ;)

Worth a close up look at the soldering of that 3pdt foot switch.

Very tidy inside! Like it!
Thank you!! ;D

I apologize for the low-res photo. It required cropping. The attempt of taking a close-up photo of the soldering made me realize that I may be in a need of a macro lens... :icon_eek:

My first build: Aion Particle Vintage Fuzz.

Didn't turn out perfect and I've already chopped off some of the paint but I still like it.

That was meant as a compliment. I initially thought the switch had not been soldered in. Zooming in showed that there was enough solder but not too much. And, each lug looked the same.

Perhaps a higher res image would show it in a less favourable light  ;D

A batch I just recently finished up. Delay, flanger, fuzz, boost.






ElectricDruid

Wow, Bean! Those top three are *rammed*! But do you honestly need *six* trims in a single pedal? That sounds like an adjustment nightmare and a lot of support queries!
<looks closely>
Ok, so there's two MN3005's, so that's probably a bias trim and a coutput balance trim for each one, and that's four already...Ok, I think I see where you're going with this! ;)

Anyway, damn well done for getting it all in there so neatly. Lovely work.

Also I think I need to get into your PCB-as-front-panels thing. They look great.


bean

Thank, Tom! Yeah, a lot of biasing trims on those but none more than needed, haha.

The faceplate thing is fun but it can be tedious so I've been doing more waterslide lately. Actually, that's a bit tedious as well.

they're 2n5089, I think I got the pun :D

Straight forward shredmaster clone, nothing fancy. Went for simple graphics to suit my simple drawing skills  :P
