Art Vanden Berg build a High Altitude Glider Project that has performed 5 flights to date. Have a look at the great documentation of the flight system and flight results. One of the issues we have seen with all of the near space balloon projects that we have featured lately is attempting to predetermine the landing zone and racing there to retrieve the cargo. Having a plane that can
Have a look at this complex GPS guided ATV project. I can just imagine a group of these things in an amusement park allowing automated carts to provide an automatic tour. More details can be found here. Thanks Amnon "This is a kids ATV modified to be controlled from a innovation first controller (Servo stirring and Victor 884 motor controller). The controller is connected to a laptop that in
Photo frames are coming down in price as each week goes by. But what fun is it to go to the department store and pick one up. Have a look at this page for some info on a DIY AVR Photo Frame build. "Objective DIY photo frame Using AVR microcontroller. Display on QVGA TFT 3.2” 240×320 pixel 16 bit color Using BMP file format with out convert. File store
Megavolts.nl built a speed meter that can monitor the speed of his coil gun bullets. The bullet trips an entry beam and an exit beam which are at a known distance apart, this allows the speed of the bullet to be calculated and displayed. The build is detailed and includes code and schematics. Here is a Google English translation. Big thanks to the creator for translating the project to English!
Ebay is a great place to look for some vintage tech. Have a look at this CD duplicating robot that TINYenormous got for only $11. Instead of ripping out and replacing the control electronics he lucked out and found someone who had details on converting it to serial control. Thanks Ross. "I bought it intending to put an arduino in the place of the control board and probably have
Have a look at the TinyProjector Lab Notebook project for some cool laser projection prototyping. See two of the ten prototypes below. Via: Elektronika "The biggest challenge for designers of mobile communication devices is presenting large amounts of information on very small displays. As the form factor of these devices continues to get smaller and our demand for mobile information continues to grow, the task only gets more difficult.
Connecting a keyboard to a microcontroller project could be a useful addition. Even if it is to be used as a code input device it could be more convenient than using a key matrix. The guys over at Nerd Kits have put together an informative video that is based on the NerdKit however it is applicable to any microcontroller. "The PS/2 Interface is quite easy to implement. To send
