I use a Sony MP3 CD player to listen to Podcasts and to my audio Bible, also MP3. I have NiCad AA batteries in it. They were free. But, if I need to charge them, I must open the lid to get at the battery compartment.

We have a phone in-use indicator with a flashing red LED. The 9 volt alkaline battery in the indicator lasts only a month or two. I wanted to replace it with a NiCad rechargeable battery.

I want to make a low tech tracking solar accumulating barbecue and earlier this year I made my first test model. My conclusion after a couple of months of working it is that a parabolic dish is the wrong shape! This instructable is about the shape I found to replace the parabola and how you can use it to make a simple reliable solar cooker.
