The Raspberry Pi is a small, cheap single-board computer designed with tinkering in mind: there are connectors that let you add a range of existing accessories, or which you can use to design your own.
Right now on Kickstarter, you can invest in the manufacturing of an e-paper display that is designed specifically to fit directly onto Raspberry Pi without the need of external wires or connections.
Percheron Electronics, the display’s creator, is seeking crowd funding for the e-paper display HAT on Kickstarter. You can pledge £39 (approximately $57) for a single, £75 (approximately $110 for a twin pack or £180 (approximately $264) for a five pack of circuit boards. All pledges require a $15 shipping fee, as well.
The E-Paper Display HAT is made from a circuit board that uses Raspberry Pi’s Hardware Attached on Top (HAT) specifications and compatible pins so you can connect the2.7-inch display directly on top of the mini computing device.
The screen has a 2.7-inch 264 x 176 resolution e-paper display. It features a real-time clock that runs on a separate cell battery for back up when the Raspberry Pi is powered down. It can also produce an alarm signal.
Thanks to the power of Pi, you can create a lot of different projects using this mini display. In addition to having a handy-dandy clock, you could program a weather update, Twitter feed, or even pictures of illustrations.
The e-Paper display will retain the last image written to it, even when powered off. So, you could have an illustration on screen while still conserving energy.
The Kickstarter campaign lasts until May 10, but nearly all of the early bird pledges have already sold out. So, if you are interested, don’t wait too long. Expected delivery is August of 2015.
