GPS packed in a mint tin case

in AVR, gadget by DP | 5 comments

Jeremy built a tiny GPS receiver into a “Altoids” case.

This unit is explained in the video above, but is basically a GPS receiver, 1 CR1220 battery for the RTC on the GPS breakout, one of my Square Inch of Goodness boards, one 128×32 OLED display, three 6mm buttons, and a 400mAh Li-Po Battery (from Sparkfun). It even has FTDI headers on it so I can update the firmware with ease (with my own FTDI adapter!). The awesome part is that all of those things fit in an Altoids Smalls tin, measuring 2.15″ (W), 1.35″ (L), and .56″ (H), or 55mm (W), 34mm (L), and 14mm (H).

Via Adafruit.

    not sure how smart idea is to put a gps receiver inside metal box

    Also capable of producing little sparks? Or are the insides coated with plastic?

    Still wondering how it is possible to ‘see’ 7 satelites from inside a metal box… :)

      If I am mounting a circuit inside a metal box, I always use some spongy double sided tape, probably he did the same. Also I cannot see any cutouts for the display, so he is probably using it with the case open and then closing it when he puts it in his backpack or pocket.
