Countdown: Only 48 Hours Left

Dear backers & brave visitors! The home stretch is here: just 48 hrs left and we have almost reached the funding goal! Run, Forrest, Run!

If you’ve already backed Paperino (thank you!), you can help us by continuing to share the project with others!

Will Paperino work with ESP8266-based boards?

The ESP8266 is a really useful WiFi module for controlling devices over the Internet. And it has made the Internet of Things (IoT) got a lot cheaper! There are a huge number of different breakout board versions out there. A very minimalistic one is the ESP-01 PCB which you can get for around $2. It offers two programmable GPIOs which, unfortunately, are not sufficient to drive the Paperino ePaper – since we need at least six GPIOs. A better alternative are ESP-12 based breakout boards which route enough GPIOs to the outside world. Popular ESP-12 based boards are the NodeMCU and D1 mini. These boards are supported by the Paperino library and work nicely with the display:

Demo: Traffic Indicator (based on Google Maps API)

When I’m sitting stuck in traffic on my way home from the office, I often wonder about what else I could be doing if I had only checked the traffic status prior to leaving the office (e.g. … save the world?!).

This project regularly checks the real-time traffic between two fix locations (e.g. work & home) and displays the estimated time of arrival on an ePaper screen. The data is gained by triggering a webhook towards the Google Maps API. This is the first time I worked with generating & triggering webhooks; it’s nice! The sketch is only 59 lines long and can be found here: https://github.com/RobPo/Paperino/blob/master/code/examples/TrafficIndicator.ino

Update Mode #3: Fast, Mono Updates

In one of the previous backer updates, we described two update modes: Full & Partial updates. Both support four grey levels and need around 800ms at room temperature to drive the display. As an example, here is a progress bar based on partial updates:

Okay that takes a while. In general, ePaper displays are not well suited for animations but rather for static content that only updates once in a while. But there is a bonus update mode in the display controller for that: it’s called “mono” or “fastPartial”. It only drives pixels black and white (so no four gray levels in this mode) and takes around 250ms for an update. The same animation as above using the mono update mode looks like this:

$20

ePaper Display

Get an ePaper display with your name written on it (or anything else you'd like to see). Without a Paperino driver board you will not be able to change the image content and it will stay there forever. Your statement against fast-moving reality! (or a spare display)


$30

Driver Board with ePaper

A small driver module PCB, ready to be hooked-up to your own controller or incorporated onto your PCB. Including accelerometer, temperature sensor, and ePaper display. Soldering skills needed!


$39

Particle Shield (PnP)

A Plug-and-Play Micro ePaper shield for the Particle Photon, Electron, and Bluz from Bluz.io. Including accelerometer, temperature sensor, and ePaper display.


$39

Breakout Board

A universal ePaper breakout-board, ready to be wired-up on the breadboard with your own Arduino /-compatible MCU. Including accelerometer, temperature sensor, and ePaper display.


$59

Complete Starter Kit

Everything you need to start playing around with your next ePaper based project: Particle Photon and Paperino Shield for the Photon, including accelerometer, temperature sensor and one ePaper display.
