DIY USB CHARGER

thingiverse

Hi! I was tried of having my phone running out of battery and I had some modules laying around so I decided to make a Rechargable USB charger (It sounds weird to me). I used some thing I used before for some simple Arduino projects that are the listed below: 1 x Step-up Boost Module (http://dx.com/p/usb-dc-0-9v-to-5v-voltage-step-up-boost-module-blue-silver-193257) 1 x Mini USB 1A Lithium Battery Charging Board (http://dx.com/p/mini-usb-1a-lithium-battery-charging-board-charger-144856) 1 x Rechargeable 18650 Lithium Battery It took 47 Minutes to have everything printed out. Every comment and suggestions will be highly appreciated. NOTE: The other .stl file is for a charger I want to make using the same modules but adding a solar panel, but when I tested it out the solar panel wasn't giving enough power to make the step-up boost module work. If anyone want's to know what kind of solar panel I wanted to use is this: 1 x DIY Solar Panel Motor Drive Charging Board (http://dx.com/p/diy-solar-panel-motor-drive-charging-board-black-2-pcs-229655) SORRY FOR MY ENGLISH! Instructions This a simple connection project, the only tricky part is putting everything together inside the housing, but nothing that a sandpaper cannot make. Solder the pieces together as in the image (negative together) The common of the switch goes to the battery an the side to each module. Before closing and putting glue to stick everything together TRY IT. If you need help, just leave a coment and I'll try to help (I'm not an expert)
