Two Wavebubbles. Left is an earlier revision with the top removed and with external antennas. Right is v1.0 with internal antennas, fit into a pack of cigarettes.

The device is lightweight and small for easy camouflaging: it is the size of a pack of cigarettes. An internal lithium-ion battery provides up to 2 hours of jamming (two bands, such as cell) or 4 hours (single band, such as cordless phone, GPS, WiFi, bluetooth, etc).
This article is the first of a series that will document the development of a low cost, open source wireless streaming internet radio receiver. All construction details, including schematics, source code, and even the design process itself will be documented on this blog. Comments and (constructive) criticism are welcome.

This is the second part of an ongoing series about building a low cost, open source streaming internet radio. if you haven’t already, check out part one for some background about the project. Onward… In part one , I discussed the merits of streaming internet radio and the motivations for my Wifi Radio project. Now it’s time to start looking at what hardware can make this project a reality. Before we get started, let’s review the requirements list from last time. Requirements:
