![]() ![]() At the moment it’s nigh-on impossible to buy an e-ink display as a consumer unless it comes bundled as part of an e-reader like a Kindle or a Nook and that makes them very expensive. Here at the Foundation, we’re watching the development of e-ink products with great interest. Once you’ve programmed your Pi and updated your E Ink screen, you can detach it from the Pi and wow those you meet with your magic power-free digital name badge!Īnd if you buy yourself an E Ink HAT, you can even have a go at this Monzo-powered money tracker.īack in 2013, our Director of Communication, Liz Upton, wrote a post about Max Ogden’s Kindleberry Pi build, commenting the following: Yes, just like this one, pHat badge is a case for showing of your pHats, look mum no power! /AwtgirUqUo In case you’re looking to add a little more colour to your display, the Pimoroni red, white, and black Inky pHAT is an add-on designed for the Raspberry Pi Zero.Ī quick and effective project for a smaller display like this is a Raspberry Pi Zero name badge, and we’ve seen our share of them at tech events and Picademy training sessions. Simply push it in place on the GPIO pins, download the library to your Pi, and you’re good to go. The Pi Supply PaPiRus comes in many shapes and sizes as an easy-to-use Raspberry Pi HAT (Hardware Attached on Top). If you want to buy a smaller display, or don’t have access to an old e-reader, you’ll find many online hobby retailers selling E Ink screens in several sizes and colours. If you have one to hand and want to get making, you’ll find an abundance of tutorials for notification displays and low-power minimalist computers using e-readers. Secondhand e-readers are fairly easy to pick up from websites such as eBay, from your local carboot/yard sale, or from book-loving friends or family members. This bike computer by David Schneider makes use of that trick: 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. The only thing missing is the screeching connection tone. If 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. And with e-readers now in their teens, there are plenty of forgotten devices collecting dust in drawers, ready to be repurposed. Plus, they’re easy to read in sunny conditions, which isn’t always true of LCD screens. So 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. E Ink displays for your Raspberry Pi projects By applying the correct charge, you control whether the black or white particles come to the surface. The microcapsules consist of negatively charged black particles and positively charged white particles. They contain tiny microcapsules suspended in a liquid within a film layer. ![]() Weather and new display using a Raspberry Pi Zero and Kindle e-reader by Luke Haas E Ink displaysĮ 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.Į Ink displays work using negative and positive charges. ![]()
