What’s on *YOUR* workbench?

Something went wrong after the box up.... Had it working fine on the auditorium... Drilled an enclosure for him,boxed it up, nice and pretty offboard wiring... fired it up and smelled the magic sauce brewing and all the leds went out in a glorious stench.... Double checked and all my wiring was correct...lol

Did you smoke the FV-1 or the regulator?

Or did you blow the protection diode some how?

Pics we need pics.

Wrapped up the wiring yesterday/last night. A few hiccups but ...

Not the first time I've wrote something on a lid, but first time I've done more than a scribble.
The recipient is heavily into the Mexican wrestling scene, so I look forward to what art my friend will put on the pedal's face.
(see bottom of post for an art-sample)
That Lucha love and lore also goes towards explaining my attempt at the Mayanesque glyph/logogram of BALAM, ie how you spell Jaguar in Mayan.


Sounds very good dimed. I could build this thing without a VOL pot, like Union Tube & Transistor's Bumble Buzz.
Very smooth fuzz, not at all what I was expecting with the PNP flipped, but I didn't mess with the trimmers. The sag trimmer is set at the Bosstone Stock 18k, so maybe I'll get to play around with it again before my friend's done painting the enclosure.

I do wish the breadboarding of this circuit had been successful, as I would've liked a bit more volume on tap (easily gets unity) and maybe a smidge more gain. Maybe I'll try to breadboard it again, address the volume and gain...



Layout and schematic are here.







Here's a sneak preview of my friend's art for a project near and dear to me. It was a mind-blowing experience.
I've been sitting on this for months, waiting for some parts and and the universe to align...

PS: Thanks Chris!😉

Heh, reminds me of this Malekko pedal. Back in the day most pedals seemed to come pre-loaded with a battery, so I went through the trouble of opening every single one to remove any.... But the Malekko one had a rather realistic glistening plastic roach in it. It startled the fuck out of me, and I nearly dropped the pedal.

Oddly enough I pulled all the LEDs and the dang thing works….

... Nah took another swing and it's just that he installed 470R instead of 4.7K for all the led resistors.... The pedal is still working without leds... about to pull them in a bit and get it back working again...

I had a pedal just refuse to work because of a busted led before. I suspect the busted led absorbs so much current that the pedal doesn’t turn on?

They could have easily tiled at least 10 of them on one board with plenty of room left for V-cuts and the guide holes for automatic assembly. Of course, there was an option for me to panelize the design and add V-cuts, but they charge extra if I do that. But not if they do it themselves in this super wasteful way??View attachment 108085

Oh yeah, that would have made a lot more sense.
 
After making some (good) noise with a friend on Friday, I was inspired to bang out a few more PCBs. I am down to 18 unbuilt PCBs (6 before any new purchases). I have 5 finished boards that need cases, including my Darkglass Alpha Omega clone. I did get the case for that and can't wait to finish it and share because the new Phido Sound Bass style looks AWESOME.

Talking 90's while jamming made me decide to work through a Muffinator Fuzz. I put it together and tested it out, and it's All But Case and ready to find a home. I set this one up with two pairs of standard 1N4148's and two pairs of penny Germaniums (1N192 I think). Listening to it, gave me some ideas on what to do to make it better, but I definitely like the strong variations between clipping stage settings.

Which made me feel like I needed to fill the printed case I have, so Sunday was time to build the 2nd Argand Plane (Small Stone) Phaser. I finished the PCB last night, and got it housed today, so I will have a unit to lend out for testing and feedback. I built this one using the alternative resistor/capacitor modifications in the AionFX build sheet, and it does a better job of matching the signal combination volumes - flipping the switch in the middle of playing does not lead to unpleasant jolts of sound.

I also had some time to push along an idea I have to build out a stereo version of Craig Anderton's original Optimum Fuzz (Op Amp Comparator style), including a +/− 9V power section using a TC1044, with a "starve" adjustment so I can squeeze the range from 18 V down to about 7.5 V. This (left) is working fine and I think I am going to render this into a PCB block for general use. The optimum fuzz, with a JFET booster, might be working - I've traced it with signal generator and it's distorting - but I need to see how it sounds on the Auditorium board because I suspect it's just doing one thing. On the scope it's pretty much either on or off with no real transition. Maybe that will sound fine with a real guitar signal with very-low voltages. I am looking to recreate something I made in the 80's that was really gated and chewy (I think my less-knowledgeable self was building with whatever parts I had or could buy at the local Radio Shack. I think I need to go read more on Op Amp functioning so I can figure out how to transition more from clean to slamming the Op Amp rails.

All of which gets me to Muffinator Fuzz #2 - I am going to build with 4148s and LEDs for the first clipping stage, and Si and Ge for the 2nd stage. Based upon what I've heard so far, I think this will provide some interesting range in dynamic capabilities.
