Demo and prototype build of my Arduino Mini GPS in an Altoids Smalls Tin.

Components:
Adafruit Ultimate GPS V3
Adafruit 3V Pro Trinket with battery plate
Adafruit 128x32 OLED SPI Display
110 mAh LiPo battery
Altoids Smalls Tin, electrical tape, wire, etc.

It gets about 3 hours of battery life with normal use where it can get a satellite fix. Full charge on the battery should last months if you don't use it much. I carry it with me everyday and only turn it on about one a week to show someone. Reactions are pretty interesting.

You should be able to build your own using the same organization of components I used in the tin. Because everything has to come out of the tin to charge the battery, there have been a couple times that I loosened a solder joint. Just had to heat up all my solder joints on the wire and it was fine. Not a big deal but something to be aware of. That is why I'd recommend a full size tin where you can charge it without taking it out.

Also, in the video I used pin 13 because my original build used it. Using pin 13 will light up the red LED on the Pro Trinket board. This is fine but better to use a different pin leaving the red led off and then you can optionally turn it on/off in your sketch by writing a digital HIGH/LOW to pin 13.

After watching that video I had to have my own. This was my first Adruino project and it was completed it in September 2015.
