Collin's Lab: High Power LEDs + Digital Color Organ. Mendocino Motor: See Photons Turned into Motion. Make: Projects See photons turned into motion with this solar-powered, magnetically levitating electric motor. The Mendocino Motor floats in its own magnetic field and converts light into electricity and magnetism, which are then converted into the motion of the motor. It provides the satisfaction of creating an amazing bit of technology, and the opportunity to explore magnetism, electromagnetism, electric motors, solar power generation, and personal manufacturing. Build the base that holds the magnets and provides a bearing point for the motor. Downloadable files for Mendocino Motor. Sound-O-Light Speakers | Make: DIY Projects, How-Tos, Electronics, Crafts and Ideas for Makers. While tidying up my workshop, I found some clear 3″ PVC pipe left over from a spud gun project (the Nightlighter 36 taser-powered potato cannon in MAKE Volume 03). Clear PVC is one of my favorite building materials, but it’s expensive, and since the last thing I need is another potato cannon, I wanted to come up with a project that would make good use of its unique qualities.

Clear PVC is stiff and dense, which makes it excellent material for audio speaker cabinets. I had seen uniquely shaped speakers made from regular white PVC, so I wondered if clear tubing could make decent-sounding cabinets that also generate lighting effects. I connected an iPod (playing ZZ Top’s “La Grange”) to a 20-watt amplifier and a small speaker, and played around with different configurations of LEDs on the speaker wire. Introducing the Sound-O-Light Speakers. Materials For bass reflex speakers: For acoustic suspension speakers: For powered/transistorized option: "The Towel" R/C Stunt Plane | Make: DIY Projects, How-Tos, Electronics, Crafts and Ideas for Makers. Conclusion Have Towel, Will Travel Know Your Controls Throttle: The transmitter’s left stick is the throttle: push it forward to go faster, pull it backward to go slower.

The transmitter’s right stick operates the elevons as follows: Pitch: Elevator signal determines the plane’s up/down attitude, or pitch. Elevon mixing: If your radio supports elevon mixing, follow the manual to achieve it. Control throws: The beginner-level control throws are ±¾" in both pitch and roll. Flight School A well-built Towel takes damage like a B-17 bomber takes flak — if the motor’s still turning, then it’s flying. CG and trim: The plane built for this article flew perfectly with the trim and center of gravity shown here. Launching: I launch the plane with my left hand, while my right thumb keeps constant contact with the right stick.

Flight training: If you’re a newbie, we recommend the Splinter Method of flight training. Have someone else launch the plane with 50% power. Best of 2012: Projects from the Pages of MAKE Magazine | Make: DIY Projects, How-Tos, Electronics, Crafts and Ideas for Makers. Looking back on 2012, it’s hard to believe we’ve been producing MAKE magazine for eight years now! I remember working on Volume 01 back in 2005 and the excitement of launching something so new and renegade.

DIY is thankfully a part of mainstream culture now, and we’re thrilled to see so many people choosing to make instead of buy. May the trend continue and grow. In 2012, we published MAKE Volumes 29, 30, 31, and 32. MAKE Volume 29 Air Guitar Hero Drop the controller and shred songs using the electrical signals from your arm muscles. We created Air Guitar Hero as a fun rehabilitation exercise for people with amputations.

How to X-Ray. “Regular radiation” such as microwave, infrared and visible light typically doesn’t have the energy needed to break chemical bonds, so we may sit out in the sun and get bombarded with a thousand watts and feel no ill effects.

Once we reach ultraviolet though, this radiation now has enough energy to break those chemical bonds –including the ones in our bodies. This means that high energy radiation such as that emitted from an x-ray tube can damage DNA, and in high enough doses may even cause radiation sickness. Acute radiation sickness occurs when your body has absorbed a large amount of ionizing radiation, usually on the order of several sieverts. What makes radiation lethal is the effect it has on DNA. When a high energy particle, be it a photon or some other particle collides with DNA it breaks bonds and rearranges the bases. Normally your cells can repair this damage, but if a cell fails at that task it often commits suicide before it divides. How to Build an X-ray Machine.

Bibliography Figure 1. Table 1. Nuclear Fusor. Nuclear fusion is the process of squeezing two atoms together so tightly that their nuclei fuse, creating a heavier atom and releasing a blast of energy. Fusion creates the inferno inside the sun — and the hydrogen bomb — but no one has yet harnessed its enormous power for peaceful uses. They’ve tried, however, often with skepticism. In 1989, physicists Martin Fleischmann and Stanley Pons announced they’d achieved “cold fusion” of hydrogen into helium at room temperature, only to face withering scorn when others failed to replicate their results. Luckily, DIY nuclear engineers can achieve honest-to-goodness “hot fusion” right at home by making a Farnsworth-Hirsch fusion reactor, or fusor for short. This mini fusor is a demonstration version — while it generates only insignificant quantities of fusion products, it does show how inertial electrostatic confinement (IEC) reactors use kinetic energy to cause fusion.

Plus, the fusor just looks totally cool. Curious? Warning How It Works. Rheoscopic Disc Coffee Table | Make: DIY Projects, How-Tos, Electronics, Crafts and Ideas for Makers. Table that was showcased at Maker Faire Bay Area. When I last visited the Carnegie Science Center in Pittsburgh, I saw a really beautiful interactive fluid exhibit demonstrating the swirly, churning patterns of turbulence. The fluid was contained in a 3-foot-diameter disc, about 2 inches deep with a sturdy glass top. A large Lazy Susan bearing supported the disc so that visitors could spin it with their hands, creating a vortex in the fluid within. The effect was mesmerizing, causing folks to spend several minutes intently watching the shimmering pearlescent fluid as they rotated the disc.

The fluid within these discs is a mixture of water, a small amount of colorant, and finely ground crystals. The crystals are slightly more dense than water, and will settle to the bottom of the container if left undisturbed. The vortex patterns that are formed within the disc are reminiscent of storm clouds swirling in the atmospheres of Saturn and Jupiter. Make Thermite, the Railway Metal — Projects. “A blast furnace that fits in a vest pocket.” That’s what Wilhelm Ostwald, a Nobel Prize-winning chemist, called thermite, which is a mix of two common chemicals — iron oxide, better known as rust, and powdered aluminum.

When combined and ignited, the stuff burns hot enough to melt iron. One of the most powerful chemical processes used in industry, the thermite reaction had a major role in the building of railroads. Through the 1920s, railroads were built by joining tracks using steel connectors, called fishplates, and several thick metal bolts. However, mechanically joined tracks made an irritating “clack-clack” sound as the trains rode over them. More importantly, bolted connections become loose, requiring a great deal of ongoing and expensive maintenance. In 1893, Dr. Thermite is still commonly used to repair existing track and in some cases, build new track ( Fe2O3 + 2 Al → 2 Fe + Al2O3 + lots and lots of heat. OneTesla DIY Tesla Coil Kits Home Page.

Made By Manish Kumar, Murtaza Tunio and Minaam Abbas The Ruben's Tube is a physics experiment demonstrating a standing wave.

It demonstrates the link between sound pressure and sound waves. A length of pipe is perforated along the top and sealed at both ends - one seal is attached to a small speaker or frequency generator, the other to a supply of a flammable gas (propane tank). Since the time averaged pressure is equal at all points of the tube, it is not straightforward to explain the different flame heights. Summer Engineering Project? : EngineeringStudents.

Shapeoko 3 - Desktop CNC Machine. Homemade Turbojet Engine : Building the Combustion Chamber. With the flame tube completed, the next step is to attach the flame tube inside the housing. The house is just a steel tube 1 or 2 inches larger in diameter than the flame tube. The two tubes are connected by a flat steel ring on the side that goes into the turbo. The other side of the combustion chamber is closed off with an end cap, a flat steel circle, that closes off both the flame tube and outer cylinder. To connect the combustion chamber to the turbo a steel reducer needs to be fabricated. This goes on the part that would normally be attached to the manifold of the car. Beer Can Jet Engine: Mark II.
