Verified Stripboard Layouts!

You da man @analogoutput! Much love x

Nice one! Love these useful circuits with standard components I don’t have to go to eBay for.

Currently working on my first stripboard layout for a passive fuzz module, will throw it up once I’ve built it…

Alright, I said I’d build it first but I’m too eager to share. It sucks! This was way more annoying than I expected!!! I should have started with the transistors. Will build, test and debug when my transistors arrive, hopefully soon. Don’t build this yet! But feel free to tell me if there are some obvious mistakes.

The 10uf is backwards. It’s based on this one: https://www.skullandcircuits.com/fuzz-1/

Great, but… perhaps an UNVERIFIED!!! stripboard should be posted in some topic other than Verified Stripboard Layouts!..

Edit: Goddamn Discourse truncates to three exclamation points!!!

Yes it’s an interresting project, open a new thread for that.

I made this fuzz a while ago. I guess it is almost the same as Sams “Fuzz for a fiver” but he did it whitout Stripboard. Its VERIFIED. But its still not the hottest Effect :slight_smile:
And you just need 1 110K Pot, not 2.

Here is the Video I think

I’ve made this one too, but it’s not the same Sam’one is active, the Skull and circuits is a passive one :slight_smile:

The S&C one seems to contain the elements you see in nearly every commercial fuzz pedal, the diode loop and dual transistors to form a negative feedback amplifier. The big difference seems to be that the diode clipping loop is before rather than after.

This video kind of broke down the landscape of fuzzz:

But in the S&C rather than a pair of diodes to ground near the output, there is a bridge rectifier near the input. Its purpose if you read the description is to provide power to the transistors by rectifying the audio signal. Hence a “passive” (in the sense of no battery required) fuzz. The diodes aren’t even in what you might regard as the audio path, except that since they don’t provide clean steady DC power the audio is affected. Cute concept. (Pretty much for synth only, I would guess, since guitar levels are so much lower, probably couldn’t provide enough voltage to power it.)

I tested them so i post it :slight_smile:

A manual & rotary dial phone gate/trigger & slutter

And a triple LFO (from this schem)
It’s a slow LFO with this cap value, after some test i just change all 1K resistors on the Rate pot by some 30K. And also i add a switch for select Square or Trangle out.

some pics of my build here

The rotary phone dialer is very cool! It reminds me of the time I could ‘dial’ a number by reapeatatly tapping the off-hook switch instead of turning the dial :phone:.

Folk lore has it that at the university campus of the Twente University in the Netherlands there was a public cell phone with a manual explaining in detail how to dial using the off-hook switch which was used by lots and lots of students to phone home.

Hey @Dud , a little tap switch stutter would make a cool optional mod no?

i’ve put a momentary push switch for manual gate, but i don’t see what you mean by

and I was going to post a photo of it, the module is finished, but I want to know what you were thinking :slightly_smiling_face:

Like the manual gate button but generating a faster “rrrrriiiippp” than the dial can generate manually. A bit like a drum roll button.
Just a thought.

!! WARNING !! THIS LAYOUT IS NOT VERIFIED !!!

Can the experts @Dud @Caustic @analogoutput @Jos @d42kn355 and everyone i forgot please check to see if there are any errors?

It’s a hex oscillator drone thingy majiggy.

!! WARNING !! THIS LAYOUT IS NOT VERIFIED !!!

Big thanks
THOGRE

And putting “Unverified” on the layout too, because google will show you the image without the surrounding text…

I think it’s hard to check a stripboard layout without the schematics it is supposed to implement…

Good news… =)
I just made a little lounge for the unverified boards.

I look forward to seeing the first graduate haha.

There is no schematic for it :man_shrugging:
