Here’s a GPS datalogger customized for trail hiking from Reed Foster over at Hacakday.io. The custom PCB was made by OSHPark upon which you can see the GlobalTop GPS module – and the Eagle CAD files are also provided. Judging from the Earth overlay image and accompanying photos that was one heck of a fun hike!

PowerBoost 500 Basic – 5V USB Boost @ 500mA from 1.8V+: PowerBoost is the perfect power supply for your portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects. Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there’s a little bit of ‘headroom’ long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance.
