I just got an open theremin uno and having a challenging time calibrating it.

Hi all!

I just got an open theremin uno.  My first theremin and my first arduino project.  Never soldered that many tiny pins to a board and it looks right but I dunno for sure.  Took several hours with that metal screwdriver they gave me to try and calibrate it.  Got squeals and gibberish runs of R2D2 noises then it would sound a tone for a hundredth of a turn and then garbage and squeals again.  

Here's how one of my attempts to tune it sounded.  Is this close to what it's supposed to sound like?

Got it sounding pretty good now.

berighteous, that was a good first time DIY theremin demo. My first build sounded like a mouse getting its nuts squeezed. I took it to work and was really proud, everyone just stared. At that time I did not know how beautiful a theremin experience could be. As I observed your technique I kept thinking I could take you at arm wrestling. (-'

lol.  Once I learn to actually play it it'll be nice.  I need to build a case for it, because the sticky backed tripod mount didn't hold for more than a few days.  It popped off and sent the theremin tumbling to the table a few days ago.  I'm going to have to build a box or a stand for the thing.

berighteous, If it works here is my favorite wood box for $15 from Amazon. It looks very good with the slide door towards the floor. Usable inside dimensions are   1.3" x 9"  x 3.5"

This box looks good also

Finding a good theremin enclosure is one of the greatest challenges in theremin design.

Have fun
