April Fool's​

 

[TrappedinMD]

Did you happen to notice a date on the "demo videos"?

 

[ToolAA]

Damn good one. Thats funny.

 

[Alan3413]

Wonder if I can cast my own bullets if I dig out the old cam from the berm.

 

[RwWilly]

I saw Jan 4th 2017 on that last vid!

 

[fidelity]

Lol, they invested a lot for a 4/1/2017 video. Speaking of which, I wonder what we might hear from a certain IP tomorrow as he continues his tradition.

Looks like a few times the guys talking almost start laughing but catch it.

Its not even midnight

Make sure use active junky and coupon code "APL17" for additional 10% off.

Thing is, this is not too far fetched. There are reliable military rounds that have embedded computers. A small solid state cam could be built. And minimal power is required. The only thing really far out there is the quality of the video.

The problem is the spin put on by the rifling. A 69 gr .223 round with a muzzle velocity of 3200 FPS when shot from a 1 in 9 twist barrel is rotating at a speed of 256,000 RPM. So in 100 yards your image will rotate 24,000 times which just might make you dizzy. YMMV

What's the RPM of that wheel?

Depends on how fast the trailer is going and the outside diameter of the tire.

I figure if you can figure out how to get a camera and transmitter to withstand the forces we are talking about in the size we are talking about, you could figure that one out too.

It got me alright. Had to google what's the new G10 ballistic and why it doesn't cause the bullet to spin..........................

They have been shooting electronics out of guns since WW II, proximity fuses for anti aircraft shells. They were developed in Maryland at the John Hopkins Applied Physics Lab and first manufactured in Silver Spring.

Google "proximity Fuse" or "VT Fuse" for lots of information but this is a pretty good telling of the story:

What was going on at the old Wolfe Motor Company building, 8621 Georgia Avenue, in Silver Spring, Maryland?

Does it say how they get the camera to TX a video that doesn't rotate?

If they ever solve the problem of developing a camera small and tough enough to sit in a bullet, electronic image stabilization is going to be required.

It will also require a high speed camera if the flight path is to be visualized. At a nominal 2000 ft/sec, covering 100 yards takes .15 secs. A standard 30 fps camera will capture 4-5 frames from firing to impact, not particularly useful.

A 240 fps "slow motion" camera will produce about a second of video at normal speed.

A 1000 fps camera, about five seconds. This is about the speed they show in the video.

Serious technical challenge indeed!

If the camera had a sufficiently fast shutter speed, that would be easy enough to decode.
