Fly back transformer? Answered

Ok, i have this transformer that i pulled out of a mac computer a couple years ago, i dont have it with me nut i think its a flyback. If it is, could i just hook it up to a battery and capacitor to make a charger or do i have to build some sort of modulator or switcher? Almost anything helps, thanks.

3 Axis Rotating Flight Simulation Rig

I have currently started building a 3 axis rotating Flight simulation rig that can simulated any 3D motion with a pilot inside the main cabin in control. I know the project needs a lot of disciplines working together (Steel design-mechanics-electrical-electronics-control-programming) So I assembled a team of engineers who got interested in the idea but we are not all highly experienced and the issue is new to all of us. So far we managed to design the rig it self as in steel design area. when we started moving along to the next phase which is the mechanical parts and joints we faced a lot of issues regarding the weight and balance of the rigs. The attached image is for a flight simulator done by a company in Russia. We have great ideas for improving that design and building our own non expensive simulator. I didn't post our full design model done in solid works cause it's not yet perfected. All I asking is that , if there is any one out there willing to help us share the knowledge or has a bit of experience in the subject, or wants to join our collaborate work, please don't hesitate to contacts us. I don't know the forum rules so I won't post my contact information here, but please feel free to discuss the subject with us on the forum, so we might benefit all together from this experience.

Robot fliers in commando competition

People and micro-aircraft race to rescue 'hostages'Robots inspired by moths, locusts, flies and swifts will take to the sky this week in an international competition for micro aerial vehicles in Agra, India. Teams will vie for the title -- as well as up to US$600,000 in funding -- for their tiny flying machines.The mission calls for squads of aerial and ground robots to reconnoitre for human 'commandos' tasked with reaching 'hostages' in a building one kilometre from the launch point. The robots will need to detect and disarm simulated chemical mines in an urban environment, and guide the commandos past guard teams to the hostages -- all within 40 minutes.The robots will use a mixture of wireless communication with a ground-control team, and autonomous navigation."It's a tough competition," says entrant Hemendra Arya, an engineer at the India Institute of Technology in Mumbai. "It really gives a challenge for the designer."Micro aerial vehicles (MAVs) are hard to detect, maneuverable, portable, and more energy-efficient than larger aircraft. The United States is currently using first-generation MAVs the size of a rucksack to warn convoys about roadside bombs in Iraq.Larger unmanned aerial vehicles such as the Predator have been used for years to spot and attack enemies, but they need an airfield. The effort to build smaller craft got a boost when the US Defense Advanced Research Projects Agency (DARPA) began sponsoring competitions in late 1996. The US Department of Defense is co-sponsoring the Indian competition. more here

long range radio control flying

Hello all...I was looking in at the discussions of the possibility of long range radio control airplane operation and can make a few comments drawn from my research into the topic, with my opinions directed toward the USA market area ; First, Americans are bound by Federal Communications Commission regulations so we must abide by them or risk steep fines or legal trouble if caught. Second, the frequencies assigned by the FCC for radio control hobby use are already allocated, so modifications to your control systems in terms of frequencies could be illegal. Third, the maximum output for radio systems in the hobby is 1000mw (1 watt), which will easily control your miniature aircraft out to 1 to 2 miles, where you will need a video camera, transmitter, reciever and viewing device to even keep track of it ! There are several manufacturers that are way ahead of most of us here - offering pre made systems that are plug and play (no head scratching needed) . Search "FPV systems" on your computer and you'll find them. Bear in mind that to use these systems in America, you will need to obtain an amateur radio (ham) operator license to be legal (again, so if you get checked, you won't get in big trouble with the Federal Government ). I'm still looking into it myself, but if you want to see a good example of a really sharp Canadian who has a handle on this, search " VRflyer" on YouTube. He started doing this quite a few years ago and has some great video of his projects and results !

Real-Life X-Wing Set to Fly

No, really.Andy Woerner and his crazy rocketeer friends have built a 21-foot long X-Wing model that can actually fly. Yes, this is a real X-Wing powered by four solid-fuel rocket engines complete with radio-controlled moving wings. It blasts off in California next week, and we talked with Andy about the project, and how they expect it will do. The X-Wing model is huge. At 21 feet long and with a wingspan of over 19 feet it is, in fact, big enough to fly a kid in. However, knowing that it will be powered by solid-fuel rockets, they wouldn't put a kid, dog, monkey or Gizmodo editor inside, even if it uses three full parachutes to land.After drawing the plans using CAD software, Andy's team and his friends at Polecat Aerospace (with the help of RMS Laser and Aerotech Consumer Aerospace) used laser cutting to make the pieces out of Baltic Birch wood. They also used solid aluminum for some parts, like the rods which are the pivot point for the wings. full story with more pics

Harry Potter flying broom idea. Would it work? Answered

               Ok, so in the past few months I've came up with an idea for a maglev-esque flying broom design after re-watching Harry Potter. It would hover over a magnetic track using two electromagnets- one in the handle and one hidden in the broom straw. The power of the magnets could be controlled via a control panel/joystick on the handle of the broom, letting the rider control the height of the broom. I'm not sure how the speed would work, but if I understand magnetic propulsion right, it should move forward by itself. Is there any way i could get it to where the rider could control the speed? And also, I'm assuming this will cost way more than I can afford, so at the moment it is all hypothetical.

Why is my quadcopter toppling when i try to fly it?

I built a quad copter. I have done all the calibrations correctly (accel, compass, rc, esc). When I arm the drone, motors and propellers are spinning. But when i give more throttle to try to hover it, it doesnt fly upward steadily. Instead it lifts backwards and falls. Why is this happening? Should I change some PID setting?

"Fly Eye" Goggles design concept - 360 Degree vision?

I've been doing some reading recently on how the mind can adapt and change it's perception of reality to accommodate new sensory inputs - like the glasses for the blind that turn visual data into sound patterns and the compass belt that helped give people an innate sense of direction.  My idea was to take a series of small webcams and arrange them on a headband so that they cover a 360 degree panorama around the wearer, then join all the images together and feed it to a set of video goggles. Initially I imagine it would be very disorientating, but hopefully after a while the wearer's mind would start to compensate for the distortion, giving them panoramic vision. I assume the various feeds from the webcams would have to be routed through a computer to process them into a single image, but I'm not sure how that could be done on a software level. Thoughts? Ideas? Help? Warnings? All appreciated. Thanks once again.

I'm looking for hard data on the relationship between typical airspeed / stall speed, glide angle, and wing loading of large gliding/flying mammals like the colugo, japanese giant flying squirrel, and flying foxes.  At first glance, Google turns up these facts with minimal digging. The catch is that the data are provided for different individuals, which is almost useless for my purposes.  Could someone point me toward a source that has all three pieces of information for the same individual, and preferably lists them for several individuals? Better still, is there an existing paper comparing the relationship between these numbers across unrelated species?
