Very often when you are building a project there are two discreet sections. How do we go about powering everything up? Just use some good old copper wires right? That’s a good solution when the sections are fixed together but what happens when one section is rotating, in this case we can use power slip ring connectors but that is not very elegant. Alan Yates had this issue when he
The Vstone/Kumotek booth at CES 2011 was lots of fun with their dancing robots entertaining the crowd. The dancing robots are being controlled using a video game like remote control. All of the actions are being manipulated using servo motors. They had a bunch of other cool things on display like the line following cars.
Jeffrey Gough from Warranty Void if Removed wanted to develop a method of printing circuit boards which was better than the current ways that a home hobbyist has available to them. He mentions the various current methods that are commonly used which are permanent marker, toner transfer, photolithography, isolation milling, UV photoplotting, laser engraving and inkjet. For his method he reverse engineered how an inkjet printer cartridge worked and made
We have seen the AR Drone here before. This is the quadcopter that can be flown around using the WiFi from your iPhone, iPad or an iPod Touch. The accelerometers in the Apple product are used to fly the device around, you simply tip it in the direction you would like the AR Drone to fly. The quadcopter has a sophisticated onboard processor which allows the AR Drone to maintain
InnoVision Labs had their HoloAd unit on display at CES 2011. The 3D effect is very good and of course there are no funky glasses to wear to get the effect. The technology uses three video images projected from above. There appears to be three angled pieces of glass on the inside of the cube which is what the image gets reflected onto.
This is a follow-up to the video last week where I showed the Camera and Camcorder Tripod Mount. Some readers sent in some emails asking how I liked the rig and what the results were like. There were lots of people who asked where I got it and where they could get one. This solution worked great for me since I could whip out a basic pattern for the shape
When using a microcontroller one of the most important feature to use is the internal non-volatile memory. This will allow you to store information that might be needed to store user selected features or system variables that need to persist power cycling. Interfacing with the EEPROM will depend on the microcontroller you are using. In this case it is an Atmega168. Our friend Daniel Garcia from Prostack has put together
