Did something similar to this with a raspberry pi, a pair of 70's ray ban bullet hole shooter glasses and a spy cam a few years back. Just got a cam that let me ditch the pi, slim it down to a Google glass type size, and stream the video to a smartphone

Any ideas on what kind of powerbank / battery to couple a RPi with for some outdoor action? A friend at work did some tests with his powerbank and his Pi2 was burning through it pretty quickly, and I don't suppose Pi3 will be any better.

Also, I love the sewing electronics into the backpack part :).

haha thanks! I lazily just used a Anker power bank: https://www.amazon.co.uk/dp/B00D5T3QK4

Two things: You can pipe the GPS right into the serial port on the raspberry pi, making the whole thing smaller.

Your GPS is an accurate time source, and assuming it has a backup battery, or at least the sight of one satellite it can spit out a timestamp that you can feed into NTP:

Thanks for the links! I guess I need to get myself a decent power bank (or make one out of all those li-polys I came back with from China). I see people recommend Anker all over HN (and Reddit, in particular Ingress players seem to like it, and that says something) - I'll probably shell out for one of those, as I don't trust any of the locally available brands (and I definitely don't trust any consumer product from Aliexpress (components are fine though)).

Neat! Did you have any problems putting the bag through x-ray machines at airports?

It wasn't too hard. The pi was disconnected and put in my camera bag in the black case, so to the average person - it was just some sort of camera gadget :P

No issues with the ribbon cable embedded in my bag either!

An interesting thing I learnt about GPS hacking was that it’s either 100% absolutely accurate or throws you somewhere in the middle of Morocco.

Imagine trying to debug this if you lived in the middle of Morocco.
