Thanks to Protostack for sponsoring the contest this week. They will be providing a ATMEGA168 Development Kit and a USBASP AVR Programmer to the winner. The development kit contains everything you need to start building ATMEGA168 circuits. The AVR programmer is based on the Thomas Fischl’s USBasp design and connects to your computer’s USB port. The USB interface is achieved by using an atmega processor and the rest is done
Designing a circuit requires reading lots of data sheets. The data sheets contain lots of parameters, for Flash memory one of those values is the number of times the device can be read and written to. In the case of a Microchip 24AA01-I/P 128byte I2C EEPROM the rated number off write cycles is 1 million. Our friend Ian Lesnet from Dangerous Prototypes has designed a device he calls the Flash
Our friend Carlos Asmat documented the process of installing a DIY Wind Turbine. The build has been broken down into 3 parts, The Wind Turbine Part 1: General Idea, The Wind Turbine Part 2: Design and Materials and The Wind Turbine Part 3: Building the Generator. As you will see not everything went as planned, I don’t think you would even consider the need to remove a huge swarm of
We have seen quite a few multi propeller RC choppers but the MegaHex – 6 Propeller RC Chopper takes the cake! This bad boy has enough power to soar to great heights carrying a decent payload. Watch the nice clear video to see MegaHex in action. The MegaHex weighs 2.8kg without batteries and with its 1kg of batteries it can fly for 14 minutes. I am thinking that this technology
Huge Tesla Coils are really cool but when you add a bit of art and danger into the mix that just makes it all that much better. Have a look at the video of the show that Arc Attack performed at the Maker Faire. If you got to see this live I am very jealous! Keep your eye on the Arc Attack show page to see them when they are
If you have lots of medications that you take this DIY Automatic Medication Dispenser by Jan Wante. There are enough compartments that you would not need to stock it very often. You would probably need to contact Jan for the code and a larger schematic since I don’t think either are posted in his article. UPDATE: Thanks to Jan for sending in a full size schematic, it has been added
If you like video games and DIY electronics have a look at this cool version of Tetris that Adam Papamarcos and Kerran Flanagan made. It’s called Human Tetris since you need to use your body to simulate the puzzle shapes to play the game. This is another great project from the Cornell ECE 4760 Course. Unlike most of the 4760 projects this team went to the extra trouble of having
