Spinning LED Box

So got this little item I'm trying to create but while it's logically simple I haven't built anything in a while So thought i'd come here and get input on what i really need to do to make things work. so the concept is simple A black box that when turned on lights up with any number of colors  (which is why this seems perfect as i can change the color with a seperate remote no complex electronics needed inside) In the center of the device is a crystal/plastic coin (power ranger, or heck Kamen Rider O items would work) and spins and that's it, it lights up and spins the coin set in the center. Souldn't be too hard right? Or is there something obvious i'm over looking

Basic spinning stage light

I'm looking for a light that I can place on the floor that would shine onto a projector screen. Something that spins with a spiral display. Either the light itself spins. Or possibly has the ability to place a filter onto a steady light and the filter spins. I'm in a band and i'm looking for something that would be strong enough to show this light display behind the drums as we play. The light and the projector screen would be relatively close to each other.

CD Player spinning device

I recently found an old AA powered Portable CD player. Upon dismantling it, I found 6 wires, since which I have tested and discovered their function. My question to you all is, would there be any danger to hooking up a larger battery to the two wires that spin the CD? I tried briefly using a 9 Volt, and the results were simply amazing. I have a hack or two that I could really use this for, and I wanted the opinions of people here to see if there was any danger to doing this.

Candle Powered Shadow Projector

If anyone has seen the movie "Sleepy Hollow" starring Johnny Depp, you must have noticed the scene where the little boy lights the candles in the punched tin can, the can starts to spin from the heat of the candles, and the punched holes in the can are shapes, a cat, a witch, a tree, etc, and these shapes are actually projected onto the walls, projected and spinning very, very slowly.  As you know this movie is set in the late 1800's, so it is not any kind of electrical thing.  I would love some ideas on how to make one of these, I don't even know what they are called, I have looked for one on ebay and here on instructables....I've been calling it a "shadow projector" but that probably isn't right.  It is an awesome little contraption, great for halloween or anytime, depending on the theme of the pictures punched on it.  Any ideas/photos/clues would be appreciated.  Thanks!

Spinning Skyscraper + Damper Ball

For the civil engineers out there, check out this daring piece of architecture: a tower whose floors are independent and can turn on voice command. Each floor is built pre-fabricated off-site and then attached to the tower, and the building creates its own energy using wind turbines and solar power. Of course, for the building to look as smooth as it does below, you'll have to ask all of your neighbors to turn their houses or offices just so.Link via GizmodoOn the subject of skyscrapers, there's more--an insight into how the Taipei 101, the world's second tallest building (at the moment), survived the May earthquake in Sichuan, China. The building uses a 728-ton ball, suspended between five floors in the upper part of the tower, to damp vibrations from high winds or ground tremors. You can watch a video of the damper ball moving during the earthquake here.Link via Gizmodo and Deputy Dog

Motors, And "9 slip contacts" so it would all be able to spin and still have power. I have no idea how to make that  I have two VCR heads, idk if they will help at all but I hear its kinda the same idea. Id also like to control motor speed/led's with my arduino if possible.

attaching a Canon 5D Mark ii to a spinning motor with variable speed controller

Hi, We're looking to attached a Canon 5D Mark ii to a spinning motor with a variable speed controller. We've attached a rough sketch to this post.  Does anyone know what kind of motor might work with a camera weighing 4.132lb/1875g? It has to be powerful enough to spin the camera solidly and at a steady RPM. We'd also like to add a variable speed controller to adjust the speed of the rotations.  We were thinking of using a battery powered drill. Is there a way to  add a variable speed control potentiometer to an electric drill? We are based in Europe. Any help would be much appreciated. Thanks! Matthew & Emelie

Rotating Antennae Wiring Question? Answered

Ok, something I've been thinking about for awhile.  Say you have an antennae/radar dish/etc that rotates 360°. Naturally, you have wires running up to the antennae connecting it to the rest of your circuit/broadcasting/receiving device. How do you prevent the wires from wrapping around the antennae and causing it to stop or causing the wires to break? I suppose you could reverse the antennae every so often to prevent this, but there must be a better way. Also, I figured you could have some sort of connection that rotated around, but it seemed that a rotating connection could be problematic if debris or something got in the way. It also doesn't seem like a very solid way to connect the two devices together.  Not actually building something here, just a curiosity. Thanks!

Which Direction Does She Spin?

Check out the optical illusion below. Since the figure is totally black, there's no depth- you can see her spinning either clockwise or counter-clockwise. Which way do you see it first? Try reversing the spin direction- moving your finger in a circular motion at the rate of rotation can help you reset. How easy is do you find it to swap perspective? Does it make your brain hurt?

How fast can you spin your Golf Ball?

I played around with some balls placed into the airstream of a little blower. Everything light enough just "danced" in the air like being hold on invisible strings. But not so much the golf ball! You would expect those dimples are good for reducing air friction but do they also offer stability in some cases by making the ball spin? Check this video I recorded while playing - to me it looks like with a proper nozzle there is even more speed possible. How fast can you make it spin?

World's smallest (manned) helicopter ready for a spin.

Those of us who've been dreaming of cheap personal air travel in the Buck Rogers, sci-fi jet-pack mode should turn their eyes towards Vinci, Italy on May 25. That's when Gennai Yanagisawa, inventor of the tiny GEN H-4 personal helicopter, will be taking his lightweight 165-pound whirly-gig on a demonstration flight.Why Vinci? According to the 75-year-old Yanagisawa, "Since the concept of our helicopter came from Italy, I always wanted to take a flight in the birthplace of da Vinci." Indeed, Leonardo's famous notebook drawings from 1493 show an "ornithopter" with a screw-like rotor. Like da Vinci's pioneering design, Yanagisawa's GEN H-4 has no tail. Instead, twin counter-rotating propellers cancel out the torque that requires single-rotor helicopters to have a perpendicular tail rotor.The GEN H-4 personal helicopter is actually available for purchase now, though Yanagisawa's company (located in the Japanese city of Matsumoto) has so far sold only six (2 in the USA).The cost for one is a reasonable $58,250 and once airborne, the GEN H-4 can fly at a somewhat sedate speed of 31 mph - slow yes, but probably faster than rush hour traffic. Veni, vidi, volanti!It's the perfect commuter vehicle! Land on the roof of your office block, maybe it folds up, but certainly just push it into the corner to make space for your workmates to land. Sure, it only does 31mph, but it can go in a straight line, over the stationary traffic.Story on InventorSpot

To generate elect. is it better to have the coil spin within the magnetic field or magnets spinning inside the coil

Which is better for making a homemade generator powered by the wind? Tesla model suggests coil spins inside of magnetic field but most electronic sites suggest having the magnets spin inside the coil windings. Are more amps produced by having the magnets spin inside the coil windings instead. Couldn't you just use most any (machine pre-wound) coils from motors rated from 1 - 5 hp. and make your own rotor where the magnets spin INSIDE the existing windings from those motors? Helpful to me since they are already rated with rpm speed. Why would you make your own with so many used motors available?

Make a hard drive constantly spin outside a PC case?

 I'm currently working on a POV hard drive clock. Instead of designing and building a separate circuit to drive the motor in the hard drive, I thought I'd just power the circuit board of the hard drive and let that spin the motor itself. I gave it gnd, 5v and 12v and it spun up, fast and stable too. ~30 seconds later, it stopped spinning and the only way to make it spin again was to turn the power off and turn it on again. Obviously this isn't good for a hard drive clock as it needs to be spinning constantly So how can I make the hard drive spin constantly? Can I pulse a request line on the IDE cable every once in a while or do I need to actually transfer data to and from the hard drive? If it isn't too complicated I could program a PIC chip to talk to the hard drive to keep it spinning but I'm not sure about the structure of the data or how to talk to the hard drive. Anyone know the simplest way to keep it spinning? Thanks, Louis.

Controller for regulating the speed and reversing the spin of AC motor at set intervals?

I would like to build a roller base that requires constant spin, and intermittent reversal of spin direction. In addition, the spin speed should be controlled so I could tune in different rpms ... eg range from 10-100. I am totally new to electromechanics and I do not know where to start. Just buying a motor and connecting it to AC should not be a problem, but the additional control seems tricky.. How can I control the spin/rpm of an AC motor, and how can I reverse the spin direction at controlled intermittent times?

How to let something spin in water without moving ? Answered

Ok, first ill explain what I have built, and excuse me if it already exists, I can't even think of how to google/name it. A can floats in water, there is a candle in the can. On top of the can there is a propeller which is stuck to the can. The hot air rises and lets the fan (and therefore the whole can) spin. The power is very little and the can tends to move to a side of the bowl and that friction stops it. Is there a balance problem ? Is the not perfect propeller working like a sail and therefore pushing it to the side ? What could I do to let the can stay perfectly in the middle while spinning ? Thanks in advance.
