David Saul is running a Kickstarter campaign to fund a new add-on board for the Raspberry Pi. Compatible with the B+, A+ and Pi 2, the PiMuxClock plugs into the 40-way GPIO header and stands up, giving you a large digital clock display. Also attached (on the enhanced version) is a temperature sensor (just because there was room on the board) and on the back is a mount point for an Adafruit real-time clock board, which means that internet connectivity is not required once the time has been set. There are various pledging options available, depending on how much you’d like to learn from and do with the kit. There are also pre-built options available if you can’t face the soldering (although this is a great kit to start with if you want to learn!)
