Electronic Hacks

Nerf Gun Hack - Secure Area and Fire on Intruders - Part 2

UPDATE: The project is complete have a look at everything here. Nerf Gun Hack part 1, part 2, part 3 This is part 2 of the Nerf Gun hack, you can see part 1 of the project here. Last time some wiring was done to allow us to remotely control the three internal motors. This time the control wires are connected to a simple circuit that uses two darlington transistors

Flash Destroyer - Testing an EEPROM device to Death

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

DIY Wind Turbine

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

MegaHex - 6 Propeller RC Chopper

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

DIY Automatic Medication Dispenser

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

Human Tetris Video Game

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

Hard Disk Drive Oscilloscope

WA5ZNU has made a cool version of the Hard Disk Drive Laser Oscilloscope. For all of those going to the Bay Area Maker Faire look out for it since it will be on display! Via: HG Forum “A local ham club is privileged to have a table at the SF Bay Area Maker Faire next weekend, and one of the demonstrations we’re doing is oscilloscopes. I’ve built this to help
