A self-tuning, wide-bandwidth portable RF jammer. The device is lightweight and small for easy camoflauging: 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).

Output power is .1W (high bands) and .3W (low bands). Effective range is approximately 20' radius with well-tuned antennas. Less so with the internal antennas or poorly matched antennas.

Self-tuning is provided via dual PLL, therefore, no spectrum analyzer is necessary to build this jammer and a single Wave Bubble can jam many different frequency bands - unlike any other design currently available! To reconfigure the RF bands, simply plug it into the USB port of your PC and type in the new frequencies when prompted. Multiple frequency ranges can be programmed in, each time the device is power cycled it will advance to the next program in memory.

While the documentation here is both accurate and complete (as much as possible), the construction of such a device is still an advanced project. I would not suggest this as even an 'intermediate' skill project, considering the large amount of difficult SMT soldering (multiple TSSOP and SOT chips, 0603 RC's), obscure parts, and equiptment necessary to properly construct and debug.
