Fresh hacks every day
Sure, the physical build itself looks great, but it's what [Michael] did with the firmware that impresses us the most. He's using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out what he calls 142 frames per second with the setup. We're not sure FPS is the right measurement, as we believe it's the multiplexing rate that he's trying to describle. It takes 144 uS to scan the entire … [Read more...]
This hardware, which was built as a Computer Engineering project by [Bryon] and his classmates, gives you feedback and control of a car though a cellular phone network. It uses text messages to communicate with a control device. This can be pretty much any cellphone, but in the clip after the break they show off an Android app which puts a pretty GUI in front of you and abstracts away the tedium … [Read more...]
[Andy] has been hard at work reverse-engineering the Nokia N82 2.4 inch cell phone display for use with an Arduino. As pointed out in the article, this same 2.4 inch display can be found in at least seven other Nokia products, so they are readily available. The panels can be found for as low as 3 pounds (or a little less than 5 dollars) on Ebay. The results are quite good and can be seen in the … [Read more...]
One high-speed photography controller to rule them all. If you're looking to photograph droplets of water splashing on a still reservoir this is the ticket. But if you're not, it still offers an incredible amount of flexibility for other high-speed needs. Inside you'll find an Arduino Mega, which has plenty of room to bend to your will. [Michael Ross] is the man behind this box. He wanted a … [Read more...]
Over the years automobile engines have become increasingly complex, and with this added complexity comes an increased reliance on intricate computer systems to run them. These control systems are typically the fruit of many hours of research and development, carefully protected by the auto makers who create them. Instead of relying on a closed system to power his car, a Finnish hacker that goes by … [Read more...]
This is a Nokia 6300 screen. It's a 320x240 display that has about 2" of diagonal viewing area and boasts 24-bit QVGA TFT technology. It's going to look fantastic in your next project and it won't be hard to get up and running thanks to the hardware and software guide which [Andy Brown] put together. He chose this display because of its features, but also because it's really easy to source and can … [Read more...]
[Jim] just finished restoring an old Seeburg USC1 jukebox for his father using an Arduino, replacing an electromechanical rats nest of wires. The stack of 45 records were replaced with an Arduino Mega 2560 with an Sparkfun MP3 player shield, and he jukebox lights are now controlled with 74595 shift registers. Because his jukebox isn't taking in money, the dollar bill validator has been modified … [Read more...]
