This circuit acts as a never-dying, forever rechargeable battery. If treated properly and with respect, it will live longer than you do! That’s right! You will die before this variable battery does! Eerie, eh? The circuit employs about $90 worth of circuitry, but it sure beats buying batteries. I use this circuit every single day when I get home from work to listen to music. Depending on your input charging method (DC, solar, etc), charging can take only minutes. With this, I can listen to music out of my computer speakers at high volume for about two hours before having to re-charge. Use it to charge your cell phone. Use it to power your radio! Use it as a portable power supply! Wire it up to a flash light, or use it to power your halloween costume! The possiblities are endless! I am selling this in kit form! See the last page of this instructable for details.
