The Spirit Radio hears all! Better be careful what you say, hehe...
The Beta Blocker Spirit Radio I've been experimenting with can surprisingly be used as a crude microphone and can even record audio sounds. Here I show how this can be done by simply attaching a magnet to the outside of the radio box!
There are no batteries or power supply for the Spirit Radio. Besides the two antennae, it consists of an inductive coil, a couple of capacitors, a resistor and a diode. That's it!
The Spirit Radio uses the power generated by it's antenna to deliver a weak audio signal, which I have wired into the computer sound-in port. The signal is amplified and altered real-time by the Mac software program Audio Hijack into what you hear.
Mr Gold tunes very specific complex waveforms to make the Spirit Radio function as a beta blocker, and it's not meant to be adjusted. Messing with it as I have may void it's intended use, or worse! (I live life dangerously, so you don't have to..;)

hi there is it possible for a radio station to secretly listen and watch someone with another version of one of these things, would like to know thnx

In WW2, the Germans were able to find the position of American forces by tuning to radios that they were using. So, all personal radios were banned by Americans. Then GI's would use whatever they had to make crystal radios to listen to local broadcasts. (Google "foxhole crystal radio")
It would be very difficult for a radio station to hear others through this radio, and it would be impossible to see someone.
With modern technology, they don't need crystal radios to see and hear through walls.

instead of using a box could it be possible to fix in a more modern mic to the crystal or would the resistance of the mic wire be too much ?

It just happened that the magnet and vibrations of the box worked out to act as a mic in this case. The spirit radio is plugged in to the "sound-in" port of the computer, so a microphone would likely work fine on it's own without the crystal or the box at all.
The crystal is a germanium diode. The diode simply converts the alternating radio waves to a dc current so the audio can be heard in an ceramic earphone of high impedence, or heard amplified by the computer.

i was thinking of a batteryless mic , using the the diode principle and a source of light to power the crystal to transmit the radio waves to a receiver ,
jmm1233 2 years ago
Ok, I get it. The light has to be alternating current to get the diode to constantly put out power. A 60 watt AC bulb makes constant power through the diode, but a laser only works with one "shot" at a time, for example
There are un-powered transmitter circuits that work by talking into a speaker. The speaker coil vibrations produce enough micro-watts of power to the transmitter to transmit...but only within a room-sized area!
