The ntpi: accurate time with a Raspberry Pi and Venus638FLPx

One of the things I’ve always loved to tinker with is time sources and synchronization. Typically this has been tied to sensible things like the Network Time Protocol and designing and maintaining time distribution systems for broadcast networks. Lately though I’ve been toying with ‘real’ time sources – GPS and MSF broadcasts. This is a quick tutorial on how to set up a Raspberry Pi, which at only a few watts makes for an economical time server, to talk to a Venus 638FLPx GPS receiver (available from Sparkfun on a suitable breakout board here).
