This circuit is the same basic 555 tone generator/ oscillator you can find in the shop, except full size components, and an added LED for a "tone on" dummy light. Use the extra 555 timers left over from my Metronome project! I'd also suggest a parallel 2.1mm power out jack, to power effect to...

The Boost comes first, then the main circuit. You can kind of intuit that from the In/ Out nets on the middle left. That is how the boost out works, no signal at zero. If its a problem, you can snip pin 1 of the boost pot and replace it with a 1k resistor. That will keep boost from going to zero.

A voltage paradigm.. +9 volts potential would be an abundance of "holes" (or, a place where an electron could go) and few electrons. "Ground" potential is where all holes are filled, and there are no excess electrons. No potential voltage -9 volts potential is when all holes are filled, and...

Can you bias it out with the trimmer?

This may be obvious, but how do you handle power filtering? Are the Time Constants effected by the filter caps in this setup? Does the circuit currently filter ripple current? (I may not be seeing it)🙃 EDIT: I see the MadBean dox show a 330r resistor switched in between VCC and the circuit...

At the risk of wasting more time,:geek: I'd ask you to verify the placement of the 10n on the output end (right side in pic) From what I can see, one side may be misplaced?

OK.. It looks like you transposed top and bottom. The cuts on the bottom need to be marked on top first, then cut on bottom, it looks like it was marked and cut directly on the bottom.

That Q1 Buffer-thing has bothered me for a long time, Thanks for your thought process walkthrough. You could build a decent pedal from the parts you took out! I would've liked to see a JFET put somewhere in there too, You know, for MOJO!⚡

My vote is Bot..

Did you happen to notice the low-pass filter formed by C5 and R8? or maybe C7 and R12? The high-pass formed by R8 and C6? R12 and C8? There are a couple more as well..:geek:

Heat sinks! The one on the top is a hair clip, but I keep both of these clipped to my iron. We used to use these back in the Pepsi Generation, but I guess they aren't used much anymore. Great for limiting heat to a part. The races in those pots are connected to the contacts by a very...

Hello! The TO-220 package is what you want. Pinouts are pretty standard. The big, grey square on the left of the board is the LM317, top down view. If you look close, the 3 light blue dots on tracks 2, 2/ 2, 3/ and 2, 4 correspond to the pins on the chip.

I found an old build! Quick and dirty. I can't remember what this was built for, but shows a good example of the projects simplicity. . Check out that casting flaw in the cast aluminum!

I've done this exact thing more than I care to mention. Last time, though, Jlcpcb sent me an email notifying me of the error! I always go the cheapest route, with no "in-house inspection", so not sure why a tiny fill layer issue caught attention. In the past, they have completely ignored such...
