Charge up with a Ljusa hand-powered USB charger

How many times have you been without a battery? I often! I then decided to hack the nice coffee grinder shaped IKEA Ljusa hand powered flashlight.

The procedure was simple it was enough to eliminate some resistors and use a capacitor sufficient to handle the charge given by the Ljusa’s dynamo.

I set the output voltage to 5 volts, and I installed a USB socket. It only remained to modify the body of the torch. Then I printed the bottom of Lyusa filament transparent leaving only the space for the female USB plug.

The result you can see in the photos. Quite nice!

Now I will never be out of battery power, simply just a bit of “movement” and the batteries of my electronic devices will be charged … at least for the time of a call.

    Of course this is several times larger and heavier than a contemporary rechargeable USB battery that can fully recharge a phone … but that’s hardly the point of the exercise. Nicely done.
