I don't know if this is the right place to ask, but I think it is.

Short background:

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?

    Welcome. Are the answers here relevant to you? While the question is a little different, a lot of the constraints of a small GPS tracker are similar. – Aurora0001 Nov 30 '17 at 18:47
  • Welcome on board. Stack Exchange has many sites, and maybe this is not the best one to ask this particular question. If I were you, I would ask it at hardwarerecs.stackexchange.com But, please do come back here for IoT questions :-) – Mawg says reinstate Monica Dec 1 '17 at 8:12
  • You will probably find something at AdaFruit – Mawg says reinstate Monica Dec 1 '17 at 8:12
  • Rather than build your own have you looked at something like Tile (thetileapp.com/en-us) – hardillb Dec 1 '17 at 18:32

I almost wonder if this is a duplicate of this question that @Aurora0001 linked. I would suggest the LightBug again.

It has got an 8 day battery life, plus solar recharging, if you can leave it attached on the outside of your purse. It's quite small (53 x 27 x 15mm), transmits to the LightBug servers every 15 minutes.

It works indoors, and can even make a noise if you want it to, to make it easier to locate. You can go to the LightBug app on your phone to locate it precisely to within a metre.
