Hey, I was going to order a minimum theremin kit, but was hoping there would be a cheap and easy way to mod on a volume antenna. is there a practical way to do this without just buying a more expensive kit?
I built the minimum theremin kit and then added the volume part of Art Harrison's 145 theremin to it. He told me that that's about as simple a volume control as is possible. It works great.
I love to tinker with electronic gadgets, building my own computers wiring my own guitars etc. That was a kool sound produced, Man! that would be a nice feedback tone on distortion Guitar.
I've build this theremin using the'' minimum theremin''Schematic but it didnt worked. I didnt found any 100uF mica capacitors..Not even at my electronic store. Is there a way to use something else? (I used TC4069UBP IC)
@BassMike80 It is a electrolitic capacitor for 100uF, it's of the most commons, check the polarity when you put it and use the the CD40106 becouse it is a Schmitt trigger, don't use the 4069. May be is later, but better than never : ) (sorry the english)
@janxzul No, DON'T use type CD40106. The circuit is specifically designed for CD4069 and won't work with CD40106. Also, there are NO 100uF ("microfarad") capacitors in the circuit. There are two 100pF ("picofarad") capacitors in the circuit. A picofarad is 1,000,000 times smaller than a microfarad.

If I can't fix them I use them for parts. The other day I found a 27 inch rca tv, and fixed it. Got it in my house. I onced bought a broken guitar amp for 20 bucks, fixed it, and gave it to my friend. Con...
If you could read schematic on electronics it is fairly easy to make. You can go to electronic project site to get a diagram of theremin. I would get parts from junked circuit boards, if I were to make one. You can use an old phone charger for the 5volt supply(they are usually close enough to 5 volts). Most junk dealers have a lot of junked electronic parts. You can buy them really cheap. They might even give it to you. Conti...
Hmmm... I posted a response the other day but I guess it didn't "take". Anyway, the project was about $20 in components and wire with lots of spares. Plus the breadboard (I had it from college - many many many years ago) will set you back $40-60. The power supply is about $50 from Kele. You can implement the circuit with a 5 VDC voltage regulator chip and a 9 VDC transistor battery.
Knowing how to fix electronics came in handy when, I lost my job one time, and survived by working at an electronic repair shop. Now its just a hobby.
A little reading on electronics will help too, specially learning the symbols of electronic components, and thier value. They even have schematic on building a guitar amp. I usually go to pawnshop, and buy broken electronics, and fix them because they sell them really cheap. Con...
It is one of Pink Floyd, not? jeje

That's kool to see DaBus going by outside da window. Where you was? HPC?
I bet a metal bento box would make a good antenna.

That's awesome. I would love some basic blue prints for that thing! Were you using delay effects with it?
Theremins are awesome. Like in Edison's Medicine by Tesla...

Great demo. I built the same one!

neat!
how much does a real one cost anyway?

there is a kit for it on the web for about $50. that's how i made mine. but the echo sound is from the little amp in the video.
