Robot Quadrotors Perform James Bond Theme (01:40)

University of Pennsylvania · 5 years ago
See how this video was made: https://www.youtube.com/watch?v OfxS6QBheGo Flying robot quadrotors perform the James Bond Theme by playing various instruments including the keyboard, drums and maracas, a cymbal, and the debut of an adapted guitar built from a couch frame. The quadrotors play this "couch guitar" by flying over guitar strings stretched across a couch frame; plucking the strings with a stiff wire attached to the base of the quadrotor. A special microphone attached to the frame records the notes made by the "couch guitar". These flying quadrotors are completely autonomous, meaning humans are not controlling them; rather they are controlled by a computer programed with instructions to play the instruments. Penn's School of Engineering and Applied Science is home to some of the most innovative robotics research on the planet, much of it coming out of the General Robotics, Automation, Sensing and Perception (GRASP) Lab. This video premiered at the TED2012 Conference in Long Beach, California on February 29, 2012. Deputy Dean for Education and GRASP lab member Vijay Kumar presented some of this groundbreaking work at the TED2012 conference, an international gathering of people and ideas from technology, entertainment, and design. The engineers from Penn, Daniel Mellinger and Alex Kushleyev, have formed a company called KMel Robotics that will design and market these quadrotors.

The single biggest reason why startups succeed | Bill Gross (06:41)

TED · 2 years ago
Bill Gross has founded a lot of startups, and incubated many others — and he got curious about why some succeeded and others failed. So he gathered data from hundreds of companies, his own and other people's, and ranked each company on five key factors. He found one factor that stands out from the others — and surprised even him.

Slow motion ball: You need a thick liquid, preferably honey, a heavy ball, and a sphere shaped container. Place the heavy ball in the lower half of the sphere. Fill the lower half of the container with honey a little more than half. If you use too little or too much, it will affect the motion of the ball. 2. Water fire starter. Credit goes to The King of Random for this idea. Be sure to check out his channel. He has a huge selection of amazing how to experiments. https://www.youtube.com/user/01032010814 You need a plastic or glass container with a curved area. The Pom bottles work great. Fill the bottle with water. Fold 2 sheets of paper in half, twice. Print or scribble a black mark on one of the sheets. On a sunny day hold the bottle near the paper, focusing the light on the black area of the paper. Once it starts to smoke and a hole begins to form, wrap the other sheet of paper around the smoking piece. Wave the papers through the air to feed oxygen to the spark. Continue this until the paper catches on fire. 3. No-leak magic bag: Al you need is a zip baggy, pencils and water. Fill the bag almost to the top. Zip it shut, and start sticking pencils through the bag. Sometimes a few drops will leak out, but overall, this is a simple yet impressive trick 4. Liquid Stacking: You'll need a tall glass or bottle. Dish Soap, vegetable oil, dark corn syrup, rubbing alcohol, water and food coloring. First add the dark corn syrup, then dish soap, then add food coloring to the water and pour it in with the bottle tilted, then add the vegetable oil (bottle tilted), and finally add food coloring to the alcohol and pour it in with the bottle tilted. 5. Invisible Bottle: You need glycerin, a glass and a bottle that will fit in the glass. Fill both glass and bottle with glycerin and place the bottle in the glass. It looks like the bottle disappears. 6. Dancing Liquid: You need a powered speaker, a tone generator (can be found online), corn starch, water and plastic to protect the speaker. Pour 1/2 cup of corn starch in a bowl and 1/4 cup of water. Mix. Pour the liquid into the speaker and generate a 60hz tone. 7. Magic Water Barrier: You need 2 of the same glasses. Hot water, cold water, food coloring and a thin piece of plastic or cardboard. Pour the hot water in 1 glass, the cold in the other glass, add food coloring, then place the plastic on top of the hot water glass. Turn the glass upside down, place it on top of the cold water glass, then carefully remove the plastic. Hot water is less dense than cold water, so it "floats" on top of the cold water. 8. Leidenfrost effect: You need a pan, water and a stove. Turn the heat on high for about 4 minutes then add the water. This experiment can stain your pans. 9. Reverse Illusion: Add all sorts of images or words behind a glass, then watch as it reverses when you add water in the glass. 10. Reversing Liquid: You need 1 big glass, 1 smaller glass, 3 mixing glasses, corn syrup, pipettes, food coloring, and clips. First pour the corn syrup into the 2 bigger glasses. Place the smaller glass inside of the bigger glass. Attach the clips to prevent the smaller glass from moving side to side in the bigger glass. Pour a small amount of corn syrup into the 3 mixing glasses. Add food coloring and stir. Fill each pipette with a different color, then add the colored corn syrup to your big glass. Turn the smaller glass carefully and watch the colors mix. Turn it back and watch them unmix. Thanks for watching! Have fun!

Amazing Secret Monitor! (How To) (02:22)

She has her own channel: http://www.youtube.com/hyderkitty Be sure to check out these videos demonstrating the same concept: http://www.youtube.com/watch?v MgN4r1YufcI http://www.youtube.com/watch?v 7e-HMjikwsY http://www.youtube.com/watch?v Du_AX7oE8HA This demonstration is 100% real. It's relatively simple to create your own. Check out some extra footage here: http://youtu.be/09_Cda9Rl5o This video shows you how to create a secret LCD monitor. The first time I read that you could do this, I just had to try. Before you attempt this, please note that I've only tried this with an LCD monitor. I don't know if it will work with any other type. Also, it may not work with certain LCD monitors. Also, the results may not be as good as the results I got. I recommend doing this project with a monitor that you don't care about losing. The results are amazing. If you are going to try and make your own, there are a few things to keep in mind. First, I would recommed using a monitor that you don't care about. I bought mine from a pawn shop for $20 dollars. Once you remove the polarized layer, you've pretty much made the monitor useless as to normal use. If you are good with repairs and that sort of thing, I'm sure you could buy a replacement filter to fix the monitor. So basically, just make sure you are ok with modifying whatever monitor you've chosen to use for this project. Once you have your monitor you need to remove the top layer, which is the polarized layer. It helps to remove the plastic frame from the front but it's not 100% necessary. Once you remove the plastic front, use a hobby knife to cut on the edge around the whole monitor. Press hard enough to make the cut but don't press too hard. That's one thing to keep in mind during this whole process is that you can completely destroy the monitor by damaging the actual LCD part of the screen. Once you make the 4 cuts, then pick a corner to start peeling the polarized layer. I used a hobby knife to "dig" under the layer so I could get a big enough piece to grab onto. Now, every monitor is different so you may experience this part a little different than the next person. You want to peel slowly to try and get the biggest pieces possible and also not to put too much force on the screen. This part could take several minutes to get all of the polarized layer off. Most LCD monitors have an antiglare layer "attached" to the polarized layer and both of those layers are glued to the hard surface of the LCD. So you may see these extra layers as you are removing them. If you're lucky you will be able to remove all 3 layers by just pulling it off. But it's likely that some glue will be left over. It's also possible that you will lift the polarized and antiglare layer but leave most of the glue. If you look closely in my video, you can see a few spots where the contrast is different. These are spots where the glue came off. If there are a lot of glue spots and it bothers you, it is possible to remove the glue by using paint thinner. But you have to be very careful. If you use the paint thinner, apply it to the glue spots and use a piece of plastic to gently scrape it off. Don't press too hard or you will destroy the monitor. Overall, I would recommend to stay away from the paint thinner and just live with the glue spots. Next you want to grab some glasses. I used a pair of the 3D glasses you get at the cinema. I never throw them in the recycle bin :). Anyway, you can open these glasses up and remove the "lenses". I ordered 2 - 6" X 6" sheets of polarized filters from a popular online science store. I traced the shape of the area where the lenses on the polarized sheets. I cut them out and placed them inside the frames. Before you cut the shape, make sure to note the proper angle of the polarized sheet with the monitor. I had to turn my sheet 45 degrees to get the correct angle. So when I traced the lens shape on the sheet, I turned the sheet 45 degrees and cut them. (In the video the sheet wasnt turned 45 degrees, but that was just a video mistake) So now you're ready for action. If you hook your monitor up to a computer and put on your glasses you should be able to see the screen just as normal. Anyone standing behind you will only be able to see a blank monitor. If you move far to the sides you can see a little bit of a negative image on the screen, but it's still very hard to make out. Anyway, enjoy!
