There are 50 or so kits spread out all over the world, some in the hands of the world's best Thereminists, which has been quite gratifying. But the project has been in a bit of a hiatus while I do more R&D, and the current tariff situation isn't exactly filling me with enthusiasm. Enclosures and antennas have been a burden for some, a wine box build is probably your best bet. I don't mind supplying hand-wound coils and any guidance you may need.
