Steerable WiFi cantenna

Despite maybe, possibly being illegal in some parts (but not many), fearless DIY-er Adrian Smith has gone forth and out-MacGyvered all other cantenna makers with his steerable, WiFi-sniffing rig. Using the requisite tin can, along with a PIC microcontroller and a couple of servos, the cantenna is able to be controlled by a custom Visual Basic program that can automagically sniff out the strongest wireless signals and zero in on them (complete with satisfying bzzzzz, whizzzz sound effects, we're sure). Unfortunately, he hasn't provided detailed step-by-step plans for the more engineering-challenged among us, so you'll need some reasonable skills of your own to put one of these to use "sharing" your neighbors' bandwidth.

Parasitic device adds baud modem tones to your wireless router

For those who are lucky enough to have only known the internet care of broadband, you might be a bit unfamiliar with the pings and screeches of days past, but for those all too familiar with dialing up in an attempt to hop on the world wide web, you could probably hum it back on command. In yet another instance of DIY creativity being used in a completely unnecessary (albeit very retro) manner, Jonah Brucker-Cohen is developing the Forward Compatible, which is a "parasitic object" that utilizes a light sensor in order to sense when a modern day modem / router is transmitting data, and subsequently belts out tones from a 2,400 baud modem from yesteryear. The FC is also designed to simply strap onto any internet-connected device without internal modifications, making it completely portable and universal in nature. So if you're interested in adding a dash of vintage to your otherwise fresh device, grab yourself an audio recording circuit, a photo-transistor, and tag the read link for a bit of old fashioned fun.
