DIY Flexible Fractal Window HDTV Antenna. When I first got an HDTV I still had SD service from my satellite company and couldn't check out the HD quality.

DIY Flexible Fractal Window HDTV Antenna

After searching the web a bit I came up with a few DIY HDTV antennas. The first one I built was a fractal antenna. It wasn't exactly to spec. Controlling the mains with bluetooth proximity. I’ve found another use for my parallel port controlled socket box ; by using it in conjunction with a bluetooth dongle, I can detect when I have wandered out of the room.

I can turn off a load of peripherals, then turn them all back on when I return to the room seamlessly. I’ve simply plugged the extension leads which power my monitors, speakers, kettle, lamps and fan into the parallel controlled socket then let a ruby script act as the brains of the operation. In order to detect only my phone I had to find out the address. Build Your Own Unified, Cordless TV-Plus-Entertainment-Center Combo. Are wires really that in-view anymore?

Build Your Own Unified, Cordless TV-Plus-Entertainment-Center Combo

Pretty much every entertainment center on the market, whether it's from Target, Costco, Best Buy or Hammacher Schlemmer is built with pre-drilled access holes (for cabinets and drawers) or come with some sort of clips that hide the wires behind the shelf supports (for an open system).

Setup a DIY Network ‘DropBox’ (aka PirateBox) PirateBox allows you to quickly setup a mobile wireless file sharing network.

Setup a DIY Network ‘DropBox’ (aka PirateBox)

Basically, it’s a P2P file-sharing device that can turn any space into a temporary, but secure wireless file sharing network. Multiple users within range of the device can connect to the network without any log-in and immediately start downloading or uploading files via their computers or mobile devices. As it is not connected to the internet, the system is secure from outside attacks. Also, users remain anonymous as no user logs are generated. The PirateBox is made up of a wireless router and light-weight Linux server connected to a USB hard drive. Build a Solar-Powered, Portable Wi-Fi Hotspot. What are the legal/TOS ramifications of using this to jump onto a stranger's unsecured wi-fi?

Build a Solar-Powered, Portable Wi-Fi Hotspot

I know my local public library's wi-fi is accessible in the parking lot and it's on 24x7—and they have no problem with someone sitting in the lot after hours, sucking down the data. (Though the police, who work at the station next door may take a dim view of your loitering, so you have to be circumspect.) But is it legal to piggyback on a private individual's wi-fi without their knowledge? And by doing so, are you causing them to be in violation of their ISP's terms of service?
