Hey all! Here's a bunch of recent builds.
BYOC VB-2

The Harmonic Sink (Harmonic Energizer)
(http://i190.photobucket.com/albums/z30/codtone/HarmonicSink_zps56575d3e.jpg)
Added an expression jack for the Q control.

Syncrotron ( Mega Chorus.Vibrato)
(http://i190.photobucket.com/albums/z30/codtone/1sync2_zpsbc24d549.jpg)
A baffling number of parameters, so I gave them appropriate- and real, thematically related names.

I built it with MN3007 and a bigger regulator for maximum head-room.

"el Segundo Primo"- working up my "useful" Spanish for my imminent trip to the US!

Made a few mods, but really dig it!.

Love these resin knobs!

Hadn't boxed it, but posted this demo a little while ago.
CMOS Theremin

Guts are a mess, originally I had a stripboard Rub-a-dub reverb in there too, but it was too noisy. I don't know what the enclosure is, but it measures 170x120x55mm, so it was fun to have that much area to work with. The large and quite thick enclosure seems to make a good aerial.

Very cool builds alltogether!
How does the Theremin work? pots instead of antennas?
Thanks!
One pot tunes the range of the RF, the other is just volume. The enclosure is the aerial. You can set it to oscillate higher as you move your hand toward it, or so it's silent with your hand near, then produce a tone that increases in pitch as you move away.

I request a demo! ;D
Dude, these all look great!
that looks fantastic
as frank zappa geek i escpecially adore the waka jawaka cover ;)
Loves those etches Mr Cod. The The Harmonic Sink looks very interesting with the external controls.. great idea.
Cody
Really great looking boxes!
Theremin seems very cool. I request a demo too. :) Is it your own design or can it be found somewhere?
Super cool and super etches I agree totally! 8) Great work!
Yes a demo of theremin would be interesting...
I love every single one of these.
Love the El Segundo Primo!
The graphic and placement is way cool.
And I can tell you with certainty that spanish is worth learning. Especially in my neck of the woods.
Those look great man!
Dat Theremin!

Cheers Guys!
If you consider a few minutes of squeaking and squawking "interesting", then here's the demo: ;)
Just watched it on facebook... awesome stuff man! 8)
Awesome builds! Love them.. Theremin is great toy to play with.
OK I want to build that theramin. Can you point me to the vero layout?
Cool stuff my son will love it.

My kids queue to play with it. :)

Awesome stuff Ben! Very cool video...
My kids just watched your video and after it finished the youngest (2 yrs 10 months) said "make one, daddy". So that's that, I *have* to make one now.
Been wanting to build a Theremin forever... This is going into the build list.
Look forward to seeing them! :D
Man! I just found a fabbed pcb of that project that InsonicBloom (Paul) had made available a while ago on BYOC! WIN!
l wouldn't mind seeing the build doc for it, if you've got it, I wanted to see if he'd changed anything...

It's printed paper sheet with hand written notes, i'll scan it and send it your way, if i don't... just recall me it. ;)
This theremin is just incredible !
The graphics are awesome, and the video is great too !
I am really wondering what mods you can use on such a "pedal"... Does it works well with other effects after it ? I am very curious to see how it can sounds with a POG for instance, or even a delay or reverb !
EDIT : ow I actually found someone using it with HOG, reverb and el capistan, it is just awesome !

Might be fun standing on one leg hopping up and down over it while playing guitar.
Thanks for the theramin vero link sir.
Having a bit of trouble following the mods and wiring you did compared to the vero drawing. Can you elaborate a bit more on the hook up for the external volume and RF controls? I assume the switch is just power interrupt.

Switch is just power interrupt, volume is just the standard voltage divider on the output. Paul revised his stripboard layout, I'd recommend you build the one I linked. Mine is built off the one he initially posted at BYOC about 5years ago, hence some differences.

Yes, of course! I had a fair bit of spring reverb on in the clip, but delay sounds cool too. I also like tremolo, flanger, phaser or Fuzz!
Spud knows tone! Awesome project, Ben!!
Cool! I like your style man.
Now you only have to practice a little with the theremin to be able to do this:

Thanks for the info. So what are the layout's 2 pots doing? On the layout there is a 10k trimmer on board, then a 1k pot off-board.
Also you just have your antenna wire connected to the enclosure right? Isn't that grounding it out? Sorry for the silly questions, I am starting to populate the vero and trying to figure out things here.
EDIT: I see you have a closed output jack so ground is isolated from enclosure yes?
THanks
I haven't built that second vero, but on the one I built one pot locates the oscillation point (set-and-forget), so that I put internal, while the other controls the range and sensitivity, that's the one I put externally.
I don't have it here now, it's on it's way to a studio in LA, but the external pot was the 10k IIRC.
You connect the antenna wire to your antenna- the enclosure in my case, but if you experiment you'll find all sorts of metal objects will work. Don't ground the circuit and the antenna. I used plastic jacks so the enclosure is isolated.

Great thank you. Final questions:
do you think the range/sensitivity pot is worth mounting external?
what value pot did you use for your volume control on the output?
all your help is greatly appreciated.
1. Nope, but YMMV.
2. A100K
Look forward to seeing your build!

Thanks M&M! ...and it'll be a while before I can pull that off on my stone age device ;D -great little clip!
