Franzis 65347 - Build your own Theremin - kit for soldering, the cult musical instrument as a DIY kit - Play the legendary sci-fi instrument - with circuit board and 80-page manual, from 14 years

A very well designed and presented kit, much cheaper than any other Theremin on the market as far as I know, $19,995 cheaper than the original RCA Theremin and it works fine. Others have given it a low rating for 3 main reasons: the instructions are in German, it's a kit, and the case is cardboard, to which I'd say that you can translate the instructions using a translation site, learn how to solder using a Youtube video, and accept that the very well designed cardboard case does the job no bother :-)

BEWARE! This requires self assembly!! (which is apparently the meaning of "selber bauen" in German) It requires the use of a soldering iron, and the (very limited) instructions are only in German. I returned it because it wasn't what I wanted, it might be OK for other people as far as you're aware that you need to solder and if you're familiar with soldering electronics (no good diagrams). The box is carton but given the price that was something expected. Go for it only if you enjoy the assembly part!

A big thanks to Steve Dwyer for his great breakdown of hitting the "sweet spot" in the tuning! Took about 5 minutes with a free chromatic tuner app but I hit it. Make sure also that your solder points are clean, with no wire strands touching other pads. I missed one between P1 and P2 and the battery started heating up! Luckily I caught it in time. You get what you pay for, but I have to say, cardboard "case" aside, this is good for what you pay. Booklet looks very interesting, if only I spoke German. Can't seem to find an English version booklet on the net.

After searching for ages for a theramin for my friend I was delighted to find this for her. I proudly presented her with it for her birthday and was shocked but the serous lack of quality and unreadable instructions. For the price I am very embarrassed

£44 for a cardboard with wood effect printing, and a circuit board. Needs assembly. Instructions in German. Some wires had become detached from the circuit board upon unpacking (ie broken but can be fixed easily with soldering iron). Quality does not match the cost.

Bought as a Christmas present. Not difficult to assemble with a bit of soldering. I"m now being driven mad with horrible theremin noises.

Has anyone actually got this thing to work?!? litterally a box of bits, all instructions in german?!?!

Cadeau de Noël, arrivé en kit il faut avoir un fer à souder, bémol la notice n'est qu'en allemand sinon exactement ce que voulait mon fils

Man bekommt eine Pappschachtel und ein paar Bauteile zum zusammenlöten. Der Bausatz funktioniert genau wie beschrieben. Und kommen Töne raus, man kann Melodien spielen wenn man den Bogen raus hat. Aber "Instrument" ist vielleicht doch nicht die richtige Bezeichnung, da hätte ich andere Ansprüche… Man bekommt das, was man bezahlt hat und der Zusammenbau hat Spaß gemacht, das Grundprinzip eines Theremins wird verständlich erklärt. Darum fünf Sterne.

Istruzioni in lingua tedesca difficili da comprendere anche per chi conosce il tedesco; tutto da montare e non in modo così intuitivo, neanche per chi ha nozioni base di meccanica/elettronica; involucro di cartone (dal disegno sembra legno), che sembra si debba rompere ogni secondo; dopo un paio di ore di montaggio, ovviamente non va. Non perdete tempo.

Dentro de la caja del embalaje viene otra caja de cartulina simulando madera, con los mandos pintados. Dentro venían los componentes para montar el circuito, que es complejo, requiere conocimiento y destrezas de electrónica. Las imagenes no se corresponden con la calidad ni uso del producto. Además, es muy pequeño y ligero ¡nada que ver con lo que parece! Nada apto para uso infantil en las edades que se recomiendan ¡ni para cualquier adulto! Su precio es muy elevado para sus características

A very elaborate manual is included, information about the history, how to play, and very clear step by step assembly instructions. However, the manual is in German only. I paid attention in school when I learned German, but I understand that many buyers will not be able to read the manual. The circuit diagram is very messy. The smaller components (chip, resistors, transistors) are already soldered on the PCB. Only a few capacitors and coils must be soldered in place. Easy for anyone who has some experience with electronics.. At first it appears to be a wonderfully polished wooden box - but it is only cardboard. There are three fake control knobs on the front, perhaps to deceive a buyer who sees a picture. Sound is produced by a built-in loudspeaker. There is no line jack for a connection to an amplifier. But of course such a jack may be added easily. What's the sound like? Well. it works. But I am afraid I will not be able to produce a nice tune. Nice to build. Nice to have. And then it goes to the attic or the flea market.
