Here is how the final board looks like ... files can find on
What do we need ? breadboard lithium battery from old cell phone, lithium charger module , 3.7 v to 5v step up converter
Change the SMD led with 3mm led and use it as power on led
Soldering the two breadboard sides together with the rest of the circuit and do some testing
Filled the holes with hot glue so the charger light can shine through it and it does
And for more stability we add this
I used the 123D design program from the Autodesk to design this project.
