hello all,
I am currently working on the project from this site:
http://interface.khm.de/index.php/lab/i … ng-device/
If you scroll down you will find a video of the theremin. You will notice a wobbly effect. The hand clearly changes the frequency, but I found the same wobbled effect of the notes. They seem to be constantly changing. So even when my hand is not there, the frequency changes.
I thought that it would be better if there was a single note/frequency. I am trying to demonstrate how a theremin works. Thus, is it possible to get rid of this wobbled effect and get a single note. I have no clue why that effect is there in the first place.
My second question is: I built his circuit on a breadboard and hooked it all up. My only problem is that the sound is much quieter than what he has. Is there any way for me to increase my volume.
Thanks.
