Getting our projects to display results usually means connecting them to a computer via RS232 or using an LCD but with a bit of work you can use VGA. Have a look at this FPGA VGA Project for some pointers. “VGA is a very friendly protocol to use with FPGA’s and CPLD’s and because of this we can easily build video controllers with basic PLDs. The VGA protocol itsself is
Kevin Pineda, Theo Jeneotopulos, Victor Cabrera, Michel Sanchez and Sergio Martinez from the Florida International University developed this IR Mouse Pen Idea they call KeyMoTe. It uses a camera which is looking at the user who holds an IR pen. The camera is connected to an arduino which sends mouse information to the computer. An off the shelf blue tooth keyboards allows the user to also type from a distance.
Our friend Bob Davis has been working on a new version of his DIY Earthquake Detection which monitors magnetic fields to attempt to predict earthquakes. This new design is using UGN3503 hall effect devices and an Arduino. “I came up with this idea over 10 years ago because animals behave strangely before earthquakes. They know something is about to happen. I also know animals can navigate magnetically. If you put
Sean Michael Ragan from Make built this Micro FM Transmitter. If you are looking to get some audio onto the radio over a short distance this project could be for you. The copper layer of the board looks very cool. “This circuit is commonly credited to Japanese multimedia artist Tetsuo Kogawa. It takes audio input through a 1/4″ phono jack and, constructed as shown, without the optional antenna connections, will
This solar tracking system uses an antenna motor which is normally used to spin an old school roof mounted antenna around. The structure is home made from some satellite dish parts and unistrut as the main frame of the solar panels. I was expecting to see several light sensors and some circuitry to see where the sun was and constantly follow it like we have seen before. But fanman1981 actually
Take a look at this cool POV clock project that PyroElectro.com did. Please lots of other POV projects below, all of these projects are cool but the Pyro Electro POV Propeller Clock is probably the best documented one I have seen! It uses a PIC 18F252 Microcontroller to run the show and fan to spin the controller. IR light is used to keep track of where the spinning circuit board
Just by adding a few wires you can use the BlinkM as a small Arduino. So next time you need a simple microcontroller that can be stuffed anywhere you might want to use a BlinkM. “The BlinkM board doesn’t have nearly the I/O pins and other features of a real Arduino board. But it is very tiny. Here are its capabilities: – 0.4″ square (MinM), or 0.6″ square (BlinkM) –
