Hey peeps.
First of all ill introduce myself. My names Omer and I live in the uk. I love electronics and will train to be an electrician soon but Im learning fast that I still know next to nothing about electronics and the way things work hehe.
Right!
What I am intending to build is a portable usb charger for my HTC Kaiser.
I want to charge this from a usb port and have some idea when the battery is full.
I ordered an 3.7v 2000mah lithium nintendo ds battery and intend to use some means to get this to a steady 5volt supply.
I have done some reading and it seems that I will need an IC to get the voltage up to 5volts. Is this true? Is this the most efficient way to do this?
will i need to use any regulators or capacitors?
how easy will it be to add a cut off charger for when the battery is full?
Many thanks in advanced
