Fresh hacks every day
This television is perfect except for its low resolution and the fact that it can't be seen by the naked eye. [Chris Shen's] art installation, Infra, uses 625 television remotes as pixels for a TV screen. There's a little bit of insight to be gained from the details which [Chris] shared with EMSL. The remote controls were all throw-aways. Even if there are problems with the buttons, battery … [Read more...]
[Mal'oo] has one of those laptop computers whose screen swivels to turn it into a tablet. But the thing is a few years old and didn't come with an orientation sensor that changes the screen between landscape and desktop, but also knows which side is up. His solution was to add a 12-axis sensor via the mini PCI express header. The hardware comes in two pieces. The first is a mini-PCIe card to … [Read more...]
If you're old enough to have used a dial-up modem we'd bet you can do an imitation of the sounds it made while connecting. Those not-so-beautiful sounds heralded the dawning of a technological era. But few actually know what each of those distinct sounds were doing. Now's your chance to learn. This post explains each step in the dail-up handshake process. This may be the most useful … [Read more...]
[Reza's] methodical investigation of this remote controlled outlet let him patch in with an Arduino using a 433 MHz transmitter. This is a single-device unit, but the techniques used here should allow you to take control of wireless rigs that have multiple modules to control many devices. We've seen some folks at our local hackerspace try to patch into the remote control itself. That used some … [Read more...]
The Belkin WeMo is a small, WiFi connected outlet controlled by a mobile device that adds Internet control to a desk lamp, coffee maker, or, if you're feeling daring, your home server. It's an interesting device, but of course there are a few security implications of having your electric kettle connected to the Internet. [Daniel] was able to get root on his Belkin WeMo and with full control of … [Read more...]
Like Cyrano giving advice to Christian from underneath Roxanne's balcony, now you too can can advise young suitors trying to win the heart of the object of their affection. [Lauren] had the idea of using objective, third-party observers checking in on her dating activities and giving advice as to what she should do next. Yes, she's streaming her dates over the Internet and asking for advice … [Read more...]
[Blake] just finished a gas sensor suite built from Gadgeteer parts. The three sensors are the cylindrical towers along the left hand side of the assembly. The one at the top (with the orange ring) is an alcohol sensor. The middle one senses ammonia and the lower sensor measures air quality. Also rolled into the mix are temperature and humidity sensors. You can collect a lot of data with this … [Read more...]
