Let's Design and Build a (mostly) Digital Theremin!

Is the song from Dark Shadows?  Do I win a D-LEV?

Good Luck to all in the new year....

Hope to own a D-LEV someday.

Thanks 

They look great....
If I ever win a lottery would love to see the D-LEV produced and promoted.  Also love to see Theremin World as a group develop and build a great analog Theremin.  Theremins with enough proper promotion will break out if made somewhat affordable and with quality.

I can always dream.....

Thanks

Yes!

Contact me via email and I'll put you on the "interested" list.  Though I have to warn you that the list is getting quite long and there are no guarantees.

Working...

I'm going to go with an integrated tuner for the next round of kits.  Artist's conception of where my head is currently at:

Something I never noticed before: it turns out that the tuner PCB has almost exactly the same dimensions as the LCD PCB.  What's also weird is the heights of them allow the tuner to nestle almost exactly underneath the near edge of the LCD PCB, so they can share a common set of 2 screws to affix them to the front panel.  I designed a honeycomb array to minimize light leakage between the LEDs:

Since there's nothing structural going on there at all, the honeycomb only takes like 12 minutes to 3D print.  The PCB cutout at the bottom is to give clearance to the LCD pins.  LED driver ICs will now reside on the tuner itself, reducing interconnect.  

The encoders will be mounted on a single PCB, with pin rather than ribbon cable interconnect.  The height there is similarly oddly rather close to fitting directly underneath the LCD PCB:

While I'm at this, all of the mounting dimensions have been normalized to simple metric values.

Looks good... if you are a fan of the E-pro / Claravox vertical format.
I think it would be good to leave the option for a horizontal layout for those who prefer the Etherwave format.

Idea for an enclosure. Vertical or horizontal.

Because the integrated tuner would be closer to the LCD, the new panel would actually fit in a bit smaller enclosure than the one I'm currently working on for the old kit:

The vertical dimension would be 215mm vs 245mm of the combined old kit tuner and controls.  The larger single opening for the new panel would allow builders to insert the new larger coils on either side too, without having to resort to cutting the box in half or otherwise making removable panels.  The goal is to make things easier for builders (and myself).  And I'd like to see the tuner up higher where it's easier to see.  Determined folks could still separate the tuner, though the single PCB for the encoders would preclude a side-by-side arrangement, so they would have to be fairly determined there.  And, you know, it's all open source, so sky's the limit and ultimately I'm not tying everyone's hands should they desire some other configuration and have sufficient gumption.  But I feel that the kit needs to be constrained more to better guide successful builds, and also to make it easier to manufacture.
