I don't know if this is the right place to ask, but I think it is.
I keep losing things temporary. That means I forget my purse at the office (or was it at home?), leave my keys at home(or were they at work?). See? I want something simple to always recover my things .
For this purpose I decided to create a GPS Tracking system. Now, I found a perfectly matching tutorial here. But the components are WAY to big for something small as my purse. I haven't found a solution for the power supply yet, but I need this and this way smaller.
I have no problem with recharging the stuff every night or so, but I need a reliable power supply system as well.
Does anyone know if there are components that are so small, and where to get them? How can I manage the power supply?
