Fresh hacks every day
Here’s a nice little discussion about reading and writing AVR flash memory that [Windel] put together. He’s using an In System Programmer to read the flash memory from an ATmega328 using AVRdude, the programming software which we used in our AVR Programming Tutorials. He covers the particulars of the commands, how this might be useful, and finishes up with … Read the rest
Want your very own Chucky doll to scare the crap out of the roommates? [Gzip] shows you how to make this happen by adding servo-based animatronics to old dolls. In the video after the break you can see the doll throw up her arms and turn her head thanks to a motor in each shoulder and one in her … Read the rest
[Billy's] work got new keys which he didn’t want to carry around with him. Instead he built this system to unlock the door via text message. It is based around a Spinneret Web Server which drives a servo motor. He’s rigged up a pipe hanger to add some leverage to the lock’s knob. We’re surprised that the servo has … Read the rest
[Lucas Fragomeni] is controlling this robot using the accelerometer on his Android phone (translated). He could have gone through our Android tutorials and developed a custom application but he took the shorter route and used Amarino, an ‘Android meets Arduino’ toolkit, to do it for him. [Lucas] combined an Arduino, a BlueSMiRF Bluetooth modem, and two servo … Read the rest
RFID cat flaps are one of those projects we see all of the time. They are generally pretty simple to rig up, not too expensive, and have a good “wow” factor for any non-technical friends or family, not to mention tremendously useful. Why did we decide to share this one? Well, for one, it is simple. It doesn’t tweet, … Read the rest
Teen hackers get ready to compete for cash and prizes. Google, the big G itself, is sponsoring a Science Fair but it’s not in a town near you, it’s online (no surprise there). Project entries will populate the content of a new corner of the Googleverse, with contestants 13-18 competing alone or as a team. The grand prize is a … Read the rest
Most of the dice related hacks we run into have to do with pseudo random number generation, but today we saw something different. This sleek looking jumbo die is actually a prize holding box opened by a secret sequence of rotations. Using an accelerometer and an ATmega 328 with a sub-micro servo to control the locking mechanism. Worried about the … Read the rest
