Robo Community has got their hands on some early prototype pictures of Robosapien V2. I find it interesting how the early prototypes look like something that would come out of a hobbyists basement. 🙂 “Before Robosapien V2 could impress your friends with his unique personality, dance moves, and bowling finess, he had to start as an idea and evolve into the super-bot he is today. Below is an exciting, behind
Popular Science Blog has an interesting article about a Chinook Helicopter ground resonance test. The videos are amazing! To learn more about ground resonance the chinook-helicopter site has some good reading and lots more videos of this bird in action. “According to PopSci’s aviation expert, Bill Sweetman, helicopters are prone to resonant effects, which is why resonance ground testing (as seen in this video) is a standard part of
The new episode of Hak.5 is out. Watch the preview above and click here to watch the full thing. “In this episode Paul takes a look at Q, the open source CPU emulator for Mac. Erin Shahan joins us to talk about RSI, the geeks natural predator. Alli shows off an idiot-proof Nintendo DS mod chip with plenty of hackability (and Doom of course). And Wess brings us a
Reconn’s World has an interesting article with sample code of a stepper motor speed controller. “While the stepper motor could be completely computer-controlled, I’d like to be able to change the speed of the motor by turning a dial. for this i’m using a linear potentiometer from radioshack (10kohm, RadioShack #271-1715.) I’ll read the voltage off of the middle pin — turning the potentiometer will cause this middle-pin voltage to
Great video showing how holograms are made. Lasers make everything cool. 🙂
Thinking about building a CNC machine? Hacked Gadgets forum member, Aaron Bowser has a site loaded with information on how to build one. Not only is there helpful information about his design, there is also a vast number of links to other resources. “The mechanical design of the machine was based on a survey of CNC machine websites and on the availability of used and surplus parts. A y-axis gantry
Carlos, an Engineering student from Quebec has made a cool little robot out of parts that can be found in most hobbyists parts boxes. “This is a small and very simple robot that requires no electronics. It is inspired on La Coccinelle. They both work according to the same principle, but their bodies and wheels are different. Also mine uses rechargeable batteries so I don’t need to buy new ones
