As a Christmas gift to the world, Lady Ada
has posted the design for a microprocessor-controlled RF jammer called WaveBubble
. It covers most of the important consumer bands pretty effectively, including WaveLan and GPS. She did an excellent job with the design, especially given the relative lack of equipment available in her lab.
I may have provided some assistance with the specs and layout for the RF chain, which is something I haven't spent much time looking at since I worked here
