jay Doscher posted a new video of the small GPS clock project he's been working on this past week. Jay is using an Arduino Micro, an Adafruit GPS breakout board and the Adafruit 4-Digit, 7-Segment LED display I2C backpack. It's pretty easy to do, and only needs soldering on the GPS and LED units. You can mount everything to a breadboard, so you don't need to commit the parts to the project permanently.
