What do you think about the advantages and disadvantages of the theremins with antenna and the optical ones ?

There really is not comparison.

The antenna variety give a nice tone with lots of options. This is because of the hetrodyne circuits.

Optical theremins just have a simple voltage circuit that varies the pitch in relation to the amount of voltage resitance that is created by the photo-voltaic cell.

Most optical theremins are hard to actually play music on.

Maybe we should hold a contest for optical theremin performances to prove the point :)

"Goblin Box"
Not sure what this is, but they say it's theremin-like.
Haven't been able to get to the videos, but it sounds curious.

""The Goblin Box is roughly based on the concept of a theremin, utilizing light sensors instead of radio waves. Two coarse tune knobs allow for a wide variety of sound, from simple tones to static chaos. This video shows it being used alone, then processed through a filter + delay."Goblin Box Demo #2YouTube via nevenen.""
