Lithium Ion Battery to AA form factor (Improved Modular Version) (with f3d)
I improved on the design to separate the voltage regulator components to easily charge the battery module.
I salvaged the battery from a discarded e-cig.
Used a couple of diodes to drop the voltage to what the electric tooth brush needed.
And the electric tooth brush is now working with a Li ion battery.
The voltage drop or modification will obviously vary from application to application.
IMPORTANT NOTE: Your electric tooth brush / or any other device might have different specs and power requirements. Please do your own calculations and test accordingly when creating the circuit. I can't be responsible for any damages.
If this designs helps you in any way, do you mind leaving me a quick tip via paypal?
