Adafruit’s Becky Stern has put together a in-depth tutorial that details how to build a GPS logging dog harness using the Atmel-powered (ATmega32u4 MCU) FLORA platform. The project can be completed with conductive thread, so there is no need to break out the soldering gun.
Aside from the Atmel-based FLORA main board, key project components include:
- FLORA sewable GPS
- Sewable coincell battery holder with battery
- 3xAAA battery holder and batteries
- Scrap of tablecloth vinyl
- Sewing needle and thread
- Sturdy tape like gaff or packing
- Clear nail polish
- Ruffwear Single Track dog backpack
Stern kicks off the GPS logging dog harness by presenting a circuit diagram that displays the following connections:
- FLORA 3.3V -> GPS 3.3V
- FLORA RX -> GPS TX
- FLORA TX -> GPS RX
- FLORA GND -> GPS GND
- GPS BAT -> positive coincell battery terminal
- GPS GND -> negative coincell battery terminal
Next up? Sew the various components, load the logging program in the Arduino IDE or Codebender and upload, paste logs into LOCUS Parser, copy the KML output into a text file and import with Google maps.
It should be noted that Stern has also created a brooch version of the above-mentioned circuit, adapting the design for fashionable humans who want to track and review their trips around town.
