Is there an audio out jack? Or would it be easy enough to make one from an old cable and connect it somehow to this for audio out?

There is an included speaker but no included audio out jack. However, some of our customers have connected their theremin to an external amp or synthesizer. You can cut up an old cable or buy on audio plug to bare wire cable. Then, you could connect the negative (black) wire to ground and the other wire to point 16B on the breadboard, the output of the amplifying transistor. This modification isn't officially supported, and you may need to use a preamp or series bypass capacitor to get it working how you want. But it's possible with a bit of tinkering.

How many octaves does it cover? Can the pitch be changed to higher or lower range

It can go from C4 to C6 (Two Octaves), and there's not a built in way to change octave range.

Can it be taken apart and put back together? Would like to use it with more than one class/studebt.

Yes, very easy to take it all apart and repeat the process. Be careful of bending the wires too often because the metal will eventually break. Just be aware and you should be fine.

Can I use a 5v usb cable to power if i add a resistor to the led?

Creator of the circuit here. I wouldn't recommend externally powering this theremin, because the separate power line would add more capacitance to the circuit. External power would be like having another object near the antenna, which would hurt the sensitivity of the system.
