Busking theremin

I would like to start busking with a theremin. I've got an etherwave standard which seems quite hard logistically to do. Does anyone know of an affordable theremin that can run off batteries etc or that would be suitable for4 busking?

I have to verify if the B3 Theremin can be run on batteries. I'll tell you this in a few hours.

Out of that the B3 manufactured from Dan Burns would be ideal for busking: Small housing and telescopic antenna (but full pitch and volume control!) and an affordable price (ca. 150 USD).

I've busked lots and lots with both the Etherwave and the Etherwave Pro. I simply use a jump start battery with a little inverter--good for two hours or more. You just plug in as to a regular wall plug. The battery cost me about $35 I believe, and the inverter can be found second hand for maybe ten bucks or less. Big fun.

I've verified it. The manufacturer of the B3 says that it can be run with 14 - 30 V DC.

So 12 cheap NiCd rechargeable batteries (1,2V per cell) will do it.

For the Etherwave standard, it's a little bit more complicated (if you do not want to use an external inverter), since it needs a bipolar voltage of at least 2 x 14V.

The modifications are described in this file on page 8:

I have heard many of you talk about the B3 theremin.

Do you have a link to a website for it? Who makes (made?) it?

Don

The B3 is made by Dan Burns. He sells his different Theremins mostly on ebay (under the pseudo "capt.theremin")

His website is www.soundslikeburns.com

The B3 is described on http://soundslikeburns.com/New_Items/b3.html

I've got one recently, but could not yet try it out for 2 reasons:
a) Got an Etherwave Standard a few weeks before and I am still exploring this.
b) Had not yet the time to change the fixed wired power supply in order to make it work on european 230 V...

But what I did already, was opening the device and having a look inside. A very interesting technology.

You should also ask Thomas Grillo here in the forum, he has already produced video recordings with the B3.

There is a video on youtube, where Barry Schwam (Schwump?) is playing simultaneously on a B3 and an Etherwave...

thanks for the advice

thanks for the advise

Eliot,
Your solution sounds like it would be easiest. Can you provide more info on this, or maybe a link where one can purchase these items?

Also, would this be a rechargeable solution?
