Fresh hacks every day
For his most ambitious build to date, [Param] thought it would be a cool idea to have a LED matrix display spitting tweets out via a WiFi connection. The build is now done, and we’ve got to hand it to him for a very nice build.
The build is based on an Arduino with a Sparkfun WiFi shield providing … Read the rest
When you move you generally load up everything you own into one truck. If your entire life is ever going to get ripped off, this is probably when it’s going to happen. To guard against the threat [Tim Flint] built his own alarm for a moving truck. If someone opens the door on the truck it’ll alert him via … Read the rest
The guys over at Section9 Hackerspace in Springfield, Missouri just finished building this treaded robot. Despite the juxtaposition of the cat, it really doesn’t defend anything. The project is a reconnaissance robot controlled over the network with video feedback.
The team started off with some lofty goals. They wanted to the robot to be able to climb stairs and … Read the rest
A while ago we caught wind of the Electric Imp, a very cool little device that packs an ARM microcontroller and a WiFi adapter into an SD card. We got our hands on an Imp last week, and now it’s time to show off what this little device can do. You can check out the rest of this hands … Read the rest
Over on the Arduino blog, the release of the official Arduino WiFi shield was just announced. On the spec page for this WiFi shield. we can see this new board isn’t a slouch; it’s powered by a 32-bit ATMega 32UC3 microcontroller, has provisions for WEP and WPA2 encryption, and supports both TCP and UDP with the Arduino WiFi library… Read the rest
Turns out you don’t need to be Superman to see through walls. Researchers at University College London have developed a way to passively use WiFi as a radar system. Unlike active radar systems (which themselves send out radio waves and listen for them to echo back), passive radar systems cannot be detected.
The system is small enough to fit … Read the rest
This simple device, paired with some creating code will let you become your own home security monitoring service. It’s called the PhantomLink and [Adam] started the project as a commercial venture. He recently decided to go open source with the hardware and will soon be posting a guide on how to program your own web interface too.
We just … Read the rest
