A time ago I decided to build a theremin. It costed a lot of time to get all the components together, but now I have everything, and started today with etching the PCB... :D

The etching process went very good! The PCB looks beautiful! (unfortunately I don't have a digital camera here).

Nice, hope you will make some demos when you get it working.

If you already have an iron and a soldering braid, it costs you about 60 euro's. (Much less than the 350 you pay for an Etherwave).
I'm just finished with etching, and that's not very difficult. That's what I can say for now. The tune is controlled by an antenna, the volume by an handheld solar-cell.

60€ is not too expensive for such a great instrument :P

I'll see if I DIY one once you post some demos (if you will do so ;))

Hmm, I know that the Australian company Jaycar Electronics do a much cheaper theremin kit (£20-£30 as I remember) with proper ariels.

Here it is. Converting the price from Australian dollars is:
36 Euros
£24.40

^Not much then.

They also do a proper theremin kit with all the tone controls, etc, for:
90 Euros
£60.90

Thanks for the link ;)

But has this thing power ? Is it as powerful as JMJ's one ? :mrgreen:
I don't think so, but is the sound good ?

I don't know, I've never built them! I think the one with the tone control will be quite like an original theremin, yes.
The power comes from an adaptor I think. Not sure about a battery....

Hm, ok, I'll try to find some informations about this one and why not demos ;)

Almost finished with soldering (only that capacitor is resting). Then I have to make coils and mount the pot's and antennae. And then... It's finished! :D

Let me know, and if the result is great, I begin to owe some money :P
