Are you interested in using an E Ink display in your next Raspberry Pi project? Let us help you get started!Weather and new display using a Raspberry Pi Zero and Kindle e-reader by Luke HaasE Ink displaysE Ink displays are accessible, they don’t need a lot of power, and they can display content without any power connection whatsoever — think Amazon Kindle if you’ve only a vague knowledge of the technology.E Ink displays work using negative and positive charges. They contain tiny microcapsules suspended in a liquid within a film layer. The microcapsules consist of negatively charged black particles and positively charged white particles. By applying the correct charge, you control whether the black or white particles come to the surface.E Ink displays for your Raspberry Pi projectsSo how and why would you use an E Ink display in your project? Simple! Aside from their low power consumption and indefinite display time, E Ink displays are relatively cheap, light, and interesting to look at. Plus, they’re easy to read in sunny conditions, which isn’t always true of LCD screens. And with e-readers now in their teens, there are plenty of forgotten devices collecting dust in drawers, ready to be repurposed.Repurposing old e-readersIf you’ve ever tried to use the ‘experimental browser’ on a Kindle device, you’ll have found yourself transported back to the glory days of dial-up refresh rates and half-downloaded images. The only thing missing is the screeching connection tone. However, by connecting your Kindle to the same network as your Raspberry Pi, you can create a web page accessible to the e-reader to display data to your E Ink screen.This bike computer by David Schneider makes use of that trick:Secondhand e-readers are fairly easy to pick up from websites such as eBay, from your local carboot/yard sale, or from
