Title: Son of Nasal Cavity (sample & hold) with bonus function generator
Post by: diablochris6 on March 19, 2016, 05:19:18 AM
I built up a version of the sample and hold section of the Maestro FSH1. I included a dry blend and an additional switching jack to add another type of noise instead of the white noise transistor in the original circuit. The function generator adds more stability in the bleep-bloop sounds this pedal makes. It is based off of the 9v generator found on a Make magazine article. I added another white noise generator, but it doesn't seem to do much. As for the enclosure decoration, I always tell myself not to attempt an etch due to unimpressive results on other builds, but then I try anyway and end up being a little disappointed again. The grungy etch kind of fits the grim content in a B-grade monster movie kind of way. I found a medical diagram of a man with his face sliced off to show the nasal cavities, and I added LED on the eye socket because LED eyes add mojo. I tried an old trick of filling the etch with melted crayon to add a splash of color (none of my children's crayons were harmed; I swiped the ones your kids get and forget about at a restaurant).

Nice job, Chris! Would love to hear it (and build it :))

You biology guys should leave the etching to us chemistry nerds ;D

Actually, my one enclosure etch was a disaster. Keep at it and you'll gett great results eventually. I think most of my problem is the ink transfer step.

Oh, you chemists. You think you have all the solutions!

I took enough chemistry to know that I can't trust atoms; they make up everything.

As far as building this, I have a prototype board for each with a couple of errors on it, but I might try to order a batch of these if there is enough interest.

Awesome! Have you done any demo with the sample and hold with the blend? Would be interesting to hear the result. :)

The only demo I have at the moment is of an older version without the blend, but I should be able to make a demo of the newest edition sometime soon to show off a little.

Here is a little video showing the blend knob in action.

Sounds awesome, Chris! Great work!

That blend works fantastic!

What kind of caps are you using for the 1uF caps?
