The extendable Arduino GPS data logger consists of a shield that is fitted with the GPS receiver, SD card reader, and accelerometer, together with an Arduino UNO board. This combination of ...

That said, it’s pretty easy to build using an Arduino, a GSM shield, a GPS system, and a handful of other components. The whole system is strapped and locked to the bottom of the saddle.

Now that tinkering has finally come to fruition with [Phang]’s TraLog shield, a single Arduino shield that combines GPS tracking with a GSM and GPRS transceiver.

It’s a relatively simple hardware build in that it is simply an Arduino Nano, GPS module, and e-ink display module wired together, but it provides an interesting exercise in running through the ...
