To my surprise I got a theremin shield in my mail that looks just like the ones I know, just slightly different. Uwe Kutschki from Thüringen redesigned an Open.Theremin.UNO with variable capacitance diode to facilitate the initial tuning. A digital to analogue converter controlled by the arduino replaces the manual tuning. As this would be a great addition I am definitely looking into his prototype and will try to implement this in a future update. More on it in the Tweaks section.

Antenna Drawing

Back form holidays with new energy, I finally got to upload a nice technical drawing of a set of antennas suitable for the Open.Theremin. You can easily bend them by hand from a 6mm aluminium tubing. The OpenTheremin can be adjusted to different types of antennas in a big range. So this is just a suggestion and you are welcome to play with different designs or materials. Also in the git repository you now find the mechanical drawing and parts from the extensions kit. See here.

Today I uploaded many great Open.Theremin builds to the community part of the website. It's great to see the craft and creativity of all of you. I hope I got all the credits right. I also put some new videos you made on testing and playing the theremin here. By looking through the internet I found this thread on audiofanzine on the open theremin with lot's of nice pictures and comments - sympa!

Finally, a Modern Theremin

Open.Theremin was featured on Hackaday. I am proud of the title you choose Mike Szczys and that you even like the quality of our documentation. Thank you. And the community is growing with many new theremins out in the world. After all the kit packing work I will now take some days of vacation in the Swiss mountains. And hopefully find some time to look more into 120 years of electronic music.
