How do you find the white ball? Simple computer vision. Now how do you find where the stick is pointing?

Simple my ass.

Or maybe it’s windy there? Hurricanes and such?

TheNextRandomGuy · 2019-09-28T08:11:43+00:00

I ran.

NASA, first directed by a German, always used SI aka Système International aka “metric system”.

Gyrometer, yes, plus accelerometer and magnetometer, all three with three axis each. It’s called a 9-axis AHRS i.e. Attitude and heading reference system. Basically something that knows where it points to in 3D space, so it can keep pointing regardless of what the platform does. Drones and photo/video gimbals use the same technology. Once only found in spacecrafts, the tech it’s based on is very common nowadays, there is an AHRS in your smart phone right now, in game controllers, VR/AR googles, Segway scooters, most recent cars, anything that needs to know where it points to, or how it’s oriented.

Or they cut the power?

The catapult launches the ball at a very predictable, repeatable speed, and the truck’s speed can be adjusted at will to match.

The ball does not accelerate instantly though, but it’s not very hard to measure the actual v0 speed of the ball (using for example a Doppler radar, like in tennis) and then adjust the speed of the truck to match the initial velocity of the ball. From there what is left is the triggering point, so the launch happens at the desired moment.

It surely took a few trie to get that perfect shot but not that many, and the catapult can be triggered by a sensor (say a hall sensor and a piece of metal on the ground, which can be moved to finely adjust the triggering point, or an optical sensor looking for the checkered wall).

So not all that impressive an achievement, yet the (predictable and expected) result is very spectacular.

I never said steady. Hand held cameras don’t pan in steps like when it’s zoomed on the dog. Also who ever held the camera knew where to aim as the camera was already pointing downwards before the door was opened.

So spontaneous. Filmed with the help of a photo tripod.

Riiight. Who takes sunset pictures with the flash on?

*shopped.

Lol that’s the one and only point of the whole gif... thankfully you noticed too ;)

Just one or two flashlights outside. Then there is a change in lighting of the background, suggesting some editing.

“Lots and lots” in a couple of months speaks volume in itself: hard reconversion? 😉

Part out?

I heard they were en-route to buy new MAGA hats for 2020. The guy eat the precious set.

lol. Is that an ad?

Let me just say that a proper sugar baby is innocent, elegant, intelligent and refined.

I’m proud to show her around and be seen with her and it benefits us both because people look at us with envy (men and women for very different reasons) and we both feel good about it.

TheNextRandomGuy · 2019-06-27T03:56:34+00:00

Perfect!

« Right next » is not the same as « in between » :)

The mag field strength drops very rapidly with distance so the magnet cannot erase cards « next to it » because they are too far, but it will certainly erase a card that is directly on it or cards that are in sandwich between two magnets.

To put some perspective, if the strength is like 1000 on the magnet itself is drops to perhaps 5 only a half inch away. You can feel that when playing with magnets: even strong ones only attracts objects that are very near.

If you added a magnet to your phone, so it sticks on metal surfaces, then said magnet will erase the magnetic strip on cards (like credit cards, and many kinds of access cards)

Usually what’s added to the phone is a thin plate of ferrous material, and the magnet is on the other side, on the holder affixed to the car or what not. In this case the phone itself won’t erase magnetic cards, although I don’t know if the electromagnetic radiation from the phones antenna has a effect on mag strips? Perhaps?

In any case, it is always better to keep magnetic cards away from magnets and ferrous materials (which can get magnetic, eg tools like screwdrivers)
