    My dad showed me how to make something like this when I was a kid. I remember moving the wire-wrapped cylinder in and out of a larger container to get different stations.

    I also remember that it worked much better at night, when the solar radiation was gone and far-off stations could be heard via the ionospheric \”bounce.\”

    But times have changed. Imagine a kid diligently assembling this project, only to tune in on Rush assaulting liberals.

    Bre, you\’re totally cool, and not just because your weekend starts on Wednesday.

    (but whatever happened to the camera balloon?)

    My first try at this kind of stuff was with an electronics kit I had. It used small springs that were inserted to a perforated board instead of using the thumbtacks or soldering. Bending the spring allowed you to insert the wire or other pieces to make the connections. The coil was pre-wound and I needed a 9v battery but after I learned to keep the springs from flying off I ended up with a working radio too. I also could make a light bulb blink and a telegraph which would play out the Morse tones via a tiny speaker.

    Thanks for stirring up the memories Bre!

    cool! Bre, why does it matter which direction the wire is wound on the tube? Isn\’t the drill press reversible? & your shirt seems to be printed inside out!

    Sometimes I wonder why RB even has these sort of pointless days where its neither news, nor something useful. Whole lot of nothing going on around here :/.

    That was a very crude version of a crystal set. What he left off was any means of tuning the thing so he could have added a variable capacitor across the coil. This could have been cobbled together with aluminium foil and an insulator like paper.

    I\’m sufficiently ancient that I recall having a real crystal set (dating back to the 1920\’s) that used a proper crystal with a joystick operated \”cat\’s whisker\” to create the rectifier to demodulate the signal. I\’m amazed that the razor blade worked.

    Hey: I have discovered that RocketBoom can be viewed via my new blackberry 8830 (via Sprint) by clicking on the \’phone\’ link! Very amazing.
    However, I have yet to figure out how to log onto the comments and enter one with it.
    Does anyone know how to enable forms/forms javascript on this phone?
    I really would like to initiate and pursue this, but simply don\’t know how to go about it, actually; this new beginning with a new technology entices me beyond bounds.
    But I keep getting this message screen in the Blackberry Browser: \’You can apply a thickbox to links and forms only\’. Does somebody have the answer? Thanks.
