Bullet RPM FormulaHere is a simple formula for calculating bullet RPM:MV x (12/twist rate in inches) x 60 = Bullet RPMQuick Version: MV X 720/Twist Rate = RPMExample One: In a 1:12″ twist barrel the bullet will make one complete revolution for every 12″ (or 1 foot) it travels through the bore. This makes the RPM calculation very easy. With a velocity of 3000 feet per second (FPS), in a 1:12″ twist barrel, the bullet will spin 3000 revolutions per SECOND (because it is traveling exactly one foot, and thereby making one complete revolution, in 1/3000 of a second). To convert to RPM, simply multiply by 60 since there are 60 seconds in a minute. Thus, at 3000 FPS, a bullet will be spinning at 3000 x 60, or 180,000 RPM, when it leaves the barrel.Example Two: What about a faster twist rate, say a 1:8″ twist? We know the bullet will be spinning faster than in Example One, but how much faster? Using the formula, this is simple to calculate. Assuming the same MV of 3000 FPS, the bullet makes 12/8 or 1.5 revolutions for each 12″ or one foot it travels in the bore. Accordingly, the RPM is 3000 x (12/8) x 60, or 270,000 RPM.

http://bulletin.accurateshooter.com/2008/06/calculating-bullet-rpm-spin-rates-and-stability/Camera in a bullet... sure... sure not gonna happen soon.Minimum frame rate of 6000 FPS, and considering each frame at a miniscule 1Meg of data, that's 6G of data per second (48GBits), and imagine all that transmitted to your Iphone, from a device which has no antenna, or battery or capacitor, near instant acceleration (which would crush/collapse the components) and then with enough centrifugal force to pull apart the lead in the bullet's core (that's why they have a copper jacket, to hold the core together). And ALL THIS data has to get to your Iphone - BEFORE the bullet impacts and the data is completely destroyed. HINT - your Iphone can't handle that data rate... neither can your computer.Alas, watching the gleeful smile drain from my kid's faces... was precious. ...and smile again, when they got the joke.

A ground to air missile is one thing, but a nano cam with gyro control is at least 20 years out, assuming they ever find a need for one, add to that wireless connectivity/heat interference, makes it a project most would put on the back burner.........of another stove no one uses.Aside from a toy, I truly don't see a marketable use for it.
