Still more tidbits. ZZZzzzz (Not a mosquito sound but snoring)

The unarmed planes, called Skeeters, are about 20 feet long.
The Air Force said a fighter jet from the 53rd Fighter Wing shot the drone planes down March 17-20 south of Panama City, Florida, as part of an operational test.
Staff Sgt. Andrew Leonhard said bad weather prevented their earlier recovery. The drones belong to a unit based at Tindall Air Force Base in Panama City.

The BQM-167A is used primarily for test and evaluation of air defense systems, with air-to-air missile training as a secondary application. It can be air or ground launched, and can carry a full range of target payloads.

This one looks like it's all in one piece. I wonder if some parachute into the water, seems like a water landing from a high speed glide would have done more do you think when it hit or maybe not?
"Both had barnacles on them, suggesting they had been in the water for some time, an official said."

"In past cases, he said, targeting drones have been found on beaches as far west as Houston." ha

Yes they have a recovery system. That is why that one is missing the tail cone.

Not very shot up was it?

Just more angles to the story.
"They are used as targets in training missions, and once they are launched, have about 40 minutes until they run out of fuel and crash into the water- that's if they aren't shot down first. "There's a pilot that will sit in a mission control area and prety much fly it by remote control. The drones are actually blown up into a whole bunch of pieces and bits."

A fair presentation. I like jars without the label though. ~43 seconds
It's interesting how the jar appears to have a shouldered look in the dark instead of the actual cylindrical shape.

My previous post was removed by the user. The post was only 20 hours old. The demonstration was "My Multi-Axis Homopolar Motor"
It had a wooden U-shaped piece of wood that on one side held an AA battery and the opposite side a smallish cylindrical magnet. There was a wire that reached from the battery over to a square magnet and a screw which spins inbetween the mounted magnet and the battery.
The feature was that you could tilt the whole unit in all directions and the screw and square magnet wouldn't fall off the tip of the battery or lose the holding power of the cylindrical magnet embedded in the arm of the little wooden mount.

The post is still up on the search page though if you catch it before it gets wished to the cornfield. ha

The only instrument you don't touch. ha
"You tune a theremin by adjusting the pitch knob and by making sure that you're standing in a proper position around the "field" that surrounds the pitch antenna. It's tuned right when you can make an octave jump with a movement of your fingers from your thumb to a full extension. Different theremin models produce different fields. Some theremins have a linear field where the scales are easy to strike in the air. Others like the B3 (mine) and the etherwave standard have a non-linear field."

And some mildly interesting resonance from around the house items. Yawn.

The producer of Bagel Boy is defeated by a jam jar. ha
I wonder what possessed him to add a copper fitting to an already simple design?
I really liked his Bagel Boy skit though, using a mostly acrylic or polycarbonate (?) potato gun to see the flame inside the tube/chamber was a nice touch too. He has a good sense of humor.
