[Tim] noticed a 2. 4Ghz WiFi spectrum analyzer on thinkgeek a while ago and got curious. He knew that the spectrum analyzers with which he was familiar were giant expensive units, so he got curious what this little dongle was.

sent in this project called Droplet. He’s been doing work with Xbees and Arduinos together and built this little toy. He describes it as “sort of like a Chumby”.

[WaveRider] is using a type of phase shift keying called BPSK to transmit digital sound and video for remote telemetry. Though a higher signal to noise ratio (SNR) is generally sought after with communications, legal limitations are imposed on total radiated power.

There are no microcontrollers in this project. In fact you wont find a single transistor. This classic regenerative tube radio, modeled after an early 20th century homebrew is complete with schematic and additional photos.

Here is a classic project used to increase wireless signal strength. Cantennas focus using a waveguide very much like a magnifying glass focuses light.

The term ‘warwalking’ isn’t used very often, but the Ekahau HeatMapper adds a new tool to the pod bound hacker’s arsenal. The tool maps out wireless access points as well as their signal strength within a facility.

Liquidware has put together an interesting kit called the WiNet. It has a battery powered touchscreen controlled by an Arduino. Using an XBee shield, it can send commands to a paired XBee and Arduino attached to a computer.
