I first heard of a 'Paraset' when I saw a message on the QRP-L reflector announcing an upcoming 'June 6th Paraset D-Day' activity. A search for more information soon revealed that the Paraset was a small vacuum-tube transmitter-receiver unit built during WWII in the UK at the Whaddon Hall headquarters of the Secret Intelligence Service Communications Unit. Known officially as the 'Whaddon Mark VII', the units were either air-dropped by parachute or carried, by the jumpers themselves, into many of the occupied countries of western Europe. . .

Good weekend project: start your own Internet radio station with peerCast. Mentioned here, very cool.

Build your own radio. . . Or anything else, for that matter. Go ahead, release the hidden scientist in you and enjoy discovering and creating.

How to build a bomb isn't all there is to the Internet as press would have you think. Anyway it's harder than just getting some plans, as this guy found out. So why not build a bomb shelter instead? Or build your own train, hovercraft, speedboat, car or plane - can't fly - don't worry build a flight simulator! Toast your success with DIY firewater cooked with your solar furnace. Enjoy your CB radio, listen to MP3s or toy with your sextant. And with all the kinky clothes and loads of pervy toys to make who has time to build bombs? I can see the bumper stickers now "Make leg spreaders, not war!"
