In this video from RoboBusiness 2008, we interview Steven from Powercast who shows off some cool wireless power technology.

From the Powercast website:

Founded in 2003, Powercast developed a receiver module with breakthrough efficiency levels. Coupled with a transmitter that sends RF energy using algorithms developed by Powercast, the Powercast Wireless Power Platform™ was born. While the concept of sending power “through the air” has been discussed for more than 100 years, Powercast is the first company to make it commercially viable. Powercast is now leading the cross-industry initiative to bring wireless power to a hundreds of low power devices.

A video from NIWeek 2008. Benjamin Cook really had fun building this electric guitar effects system based around NI hardware and LabVIEW.

This is a wireless audio processing project. A 550 MHz transmitter transmits FM modulated data to a 5600 down converter. It down converts the data to 25MHz. That gets sent to a 5640R IF-RIO card. The IF-RIO card has an FPGA. That’s where all the demodulation and audio processing happens which then gets sent out the sound card. You get very low latency audio response.
