Product Description
This is a super WOW demonstration!
How much fun can one have with a complex principle such as amplitude modulation?
A lot! Plug a LED torch into a CD player’s or iPod’s earphone socket and transmit the sound on the light beam to a solar panel. The solar panel is connected to an amplified speaker to make the signal audible.
This kit contains a pre-amp circuit that is bundled with the solar panel so that a good quality audible signal is produced and fed to the speaker as in the video below. This will make the sound audible in a classroom set-up. But if you simply want a smaller set-up then simply follow the free information in the file below. The LED torch is now readily available at bargain gift shops for $4 or less.
Included : Pre-amp kit & components, solar panel, instructions
Required ( not included ): Torch (A), MP3 player or any player with earphone outlet (B), amplified speaker such as a computer or iPod speaker (C), soldering iron, 9V battery.
