Your suggestions for etching projects

Im guessing that the Q1 is a voltage regulator

[...] what is the fet stuff on the left? [...]

Q1+R2 could be for polarity protection (p-channel mosfet (BS250) + 1M).

Bingo. I've been using this a lot lately and it works great. Voltage drop is very very small. I'm only putting this arrangement in pos ground circuits (with n-channel mosfet) and stuff with charge pumps for the MBP projects, though. Other ones are just a zener in line with +9v. Actually, I'm using the same power scheme for ALL the projects pretty much. The zener, and 100uF and 100n caps to ground for decoupling.

Here's another "extra project" that never got released. I'm pretty proud of this layout...it took 5 tries to get it right. It's a PT2399 based chorus.

Oooohh! That's an awesome little circuit! Just checked it out on the interwebs! Pretty amazing!
Really small voltage drop and wasted power!
Thanks, kothoma and bean!

I think we'll do a Phase90, but not as a single sided layout. I don't think I'm going to do a better one that what's out there. But, I got a nice compact double sided layout going. I'm thinking of adding on a transistor matcher circuit to this...as a breakaway. That would be pretty rad.

NOM stands for Normal/Open/Max (or min) and is a feedback switch.

And I would totally buy it.

It's a phaser, it's a given that you'll be first in line.  :-)

And some more. Getting pretty closed to finishing up the whole batch. About a dozen left to do.

Kinda like Pokemon..."gotta etch 'em all"

Brian, you going to release the whole batch at once and stand back and watch the madness?

LOL.... to bad he don't have a storefront. It would be better than Black Friday !

[ggarms]

I'm guessing a big drop all at once will give fx a nice set of wings!

Yup, I'm going to take great pleasure in blowing people's minds with the shear volume.

Another fun one.

I was populating the grease gun tonight and pretty much snarfed my cold beverage when I saw the middle knob on the silk was labeled "TOAN"

I just squealed like a little girl.
