Thanks to all of you who posted great explanations in the comments of yesterday’s post about a dubious way to make a metal detector from an AM radio and a calculator. Mahto submitted his trial video first (shown above), and he gets a Make pocket ref! Some notable comments: Nick Clark writes: AM radio operates […]
Folks frequently ask me what happens at Maker Faire tryouts. This episode of BBtv gives you some idea, as Greg MacLaurin demos his “Judy Phone,” a playback device via an old analog phone of bizarre Judy Garland audio recordings done for her 1960 autobiography. Note to non-fans of conceptual/installation/pomo art: Don’t bother to hit the […]
On 12/8/07 Ham radio operators, using morse code communicated by bouncing radio signals off the surface of the space station as it flew overhead, thanks Ollie AJ10! Link.
Larry writes – I have heard, even from a physicist, that it is impossible to build FM crystal radios. On the other hand some experimenters claim that they have built them. This argument intrigued me to try and build an FM crystal radio, which I have done successfully. To my surprise, the result is an […]
jmluber writes in with another radio project – In the old days, people used radios that used a germanium diode (crystal radio) to receive am radio without the need for a battery (the radio wave powers this type of radio). This site modernizes that concept by showing you how to build a shortwave radio that […]
A retro-futuro casemod built inside of an antique phone box with the restored and retro-fit phone itself on top. The phone functions as both a landline phone and works with Skype, MSN Voice, and Google Talk.

I’m really surprised that telepresence/telerobotics hasn’t caught on more than it has. IRobot was R&Ding this tech nearly a decade ago. And the tools to make it happen have only gotten cheaper and more widely distributed. In this story, reverberating around the Interwebs, Ivan Bowman, a computer programmer, works from his living room in Nova […]
