How do I turn sound into light, shine the light on o solar panel and convert it back to sound with a speaker?

I think the plans on this page give the basic idea.

and this, from the same person, does it with a laser pointer

I got these by searching for "sound modulate LED" and "sound modulate laser". The key word is "modulate". You want to use the sound to modulate the intensity of your light source. At the other end you need something which demodulates and interprets the intensity variations as sound.

LSD size for a solar light run by a 1.2v ni-cd battery garden light

We Answered:

First of all, are you absolutely POSITIVE the LED is broken? Those things are really rugged, you've got to hit them with the mower or worse to really damage them. Did you check to be sure it's not the battery that's died? The el cheapo battery that comes with the light dies fairly quickly, drop $5 on a pack of high-capacity NiMH batteries and put those in your solar light, it may stay on at full brightness all night.

If the LED really is the problem, I recommend you just replace the entire light. It's a hassle to try to replace the LED in those little circuit boards, you have to solder them in and they're all made in China by robots with little tiny hands.
