Paperino, The ePaper Display Shield

ePaper displays  (EPDs) are becoming a trend in application, just like the display used in Amazon Kindle,  for their low power consumption due to the  to the underlying ‘bistable’ display technology. These displays can continue to show information without any power at all. It is only required while updating the display with new information, otherwise there won’t be any power consumption.

Providing such revolutionary displays to your applications will be a professional approach. For this, a new crowdfunding campaign is providing Paperino, an easy-to-use, micro ePaper shield for the Particle & Arduino community. Paperino simplifies driving ePaper displays with clean, simple, and short script examples.

Thanks to the plug-and-play shield for particle family, Paperino can be used with the following boards: Photon, Electron, or Bluz without manual wiring. It can also be wired easily to be connected with Arduino and other compatible boards.

Paperino Features

Glass-free Display

Paperino is lightweight and thinner than other ePaper products because it uses a glass-free ePaper display from Plastic Logic. It weighs 1.2 grams and is only 0.5 mm thick.

Supports Four Gray Levels

Unlike many other ePaper products out there, Paperino can support four gray levels instead of two (black and white).

Fast, Partial Updates

You don’t have to wait for slow, full screen updates to load. With Paperino, you can quickly update only parts of the screen.

Accelerometer

The integrated accelerometer lets you interact with your Paperino in all sorts of ways, including tap sensing. Tap sensing capability can trigger screen updates or wake up your microcontroller.

Paperino Specifications

The Paperino breakout board can be used for manually wiring your favourite, Arduino-compatible microcontroller with 3.3 V and >4kb of free RAM.

  • Resolution: 148 x 70 px
  • Pixel density: 150 ppi
  • Grey levels: 4
  • Weight: 1.2 g
  • Thickness: 500 µm
  • Power consumption: 4.5 mA (mean current for typical image update)
  • Operating conditions: 0°C .. 40°C
  • Storage conditions: -25°C .. 50°C

You can pre-order your own Paperino for $20 and with a driver board for $30. The crowdfunding campaign still has 16 days to go, and you can learn more details by checking it out.

VGADuino-II : The New 256 Color Graphic Shield for Arduino

Arduino is pretty much famous for the numerous shields it has. These plug-and-play shields make our life a lot easier while working on some complicated projects. Among all other shields, graphic shields are getting more and more popular. A graphic shield lets you show text, numbers, shapes, and even small images on a screen, using Arduino. VGADuino-II is a new graphic shield which lets you use your TV or any monitor with VGA 15 pin as a large screen for Arduino.

It’s very exciting that you won’t have to rely on those small displays which are stacked on the shield itself, anymore. Rather you are getting a whole TV or VGA monitor to display your data. As  Masih Vahida, the creator of VGADuino, says:

VGADuino is a shield that is made for Arduino with all the libraries and samples that user can easily stack it on the Arduino board and starts programming. it can connect Arduino to any kind of TV or Monitor with VGA 15 Pin connector.

Key Features:

  • Internal functions to draw various shapes with AT-Commands and Arduino libraries
  • 11 Different font sizes with standard ASCII characters support
  • 256 color, 8bit RGB format
  • Having access to each pixel individually
  • Standard VGA DB15 output
  • Screen resolution: 800×600 60Hz
  • Actual pixels: 400×300 60Hz

Technical Details:

In VGADuino-II, NXP-LPC1756 ARM chip is used as the main microcontroller and XILINX XC95144XL CPLD for refreshing the display and taking care of the sync signals. There is also an SD Ram to keep the screen’s pixel color data.

In this version of VGADuino, each pixel is one byte, that means each pixel has 256 colors which are in standard 8bit RGB format. (3 bits for Red, 3 bits for Green and 2 bits for Blue).

It communicates with Arduino over UART using predefined AT command set. All relevant Arduino libraries are available to implement in code. The user can choose among all 11 fonts with definable background and foreground color of text.

Conductivity Shield for Arduino Uno

by PyroCat @ elektormagazine.com:

Conductivity is the ability of a material to transfer electrons. It is the opposite of the concept of resistivity which is well known to electricians. However, while we are used to address the topic of conductivity in the field of electronics, things get a little bit more complicated when we try to apply the concepts to chemical solutions such as salty water.

E-paper Shield Kit for the Teensy

shield-kits_jpg_project-body

Jarek tipped us with his latest project, an E-paper screen shield kit for Teensy. He writes:

E-paper screens have been hacked out of Kindles and store price tags for a while, but this is the first ( to my knowledge ) open-source project which offers a simple and cheap interface for E-paper. After you prototype your idea with this board, you can get the plans from my project page and integrate the solution into a project or commercial product without having to iterate fives times as I have to get the E-paper driving circuitry just right. The shield fits over most Teensy boards, and the female headers mean you can plug wires right into a breadboard or any other 3.3V microcontroller board. E-paper is sensitive to temperature, so there is an I2C sensor on board that can be used if you need to use your E-paper in harsh environments.

SoundDuino is a WAV Sound Player & Recorder Shield for Arduino. This sound shield let you record and play sound files to or from a Micro-SD memory card with all libraries and samples for the Arduino IDE.

“SoundDuino is a sound recorder and player that is able to play the sound files from the Micro-SD memory card or even record sounds to the memory with your desired file name. It supports FAT16 and FAT32 and you can easily copy your files into the memory and to play them, you only need to use the library that we give you with this shield and just send the file name that you want to play! Yes, very very easy!” Vahida explains.

This video shows the very first version of SoundDuino and some of its applications

The newest shield, SoundDuino3,  is based on NXP LPC2103 ARM7 32bit microcontroller and it can play 16 bit 48khz sound files with a very high quality. It also has audio input and output jacks, an onboard microphone as well and can work from 3.3v to 5v. SoundDuino fits nicely on an Arduino Uno and is compatible with any Arduino boards using pins GND, VCC, RX and TX. Moreover, the device is delivered with libraries and examples for Arduino IDE.

This project is now live on Kickstarter, check the campaign video

You can use this shield to announce numbers and add you own files into the memory. You can also extend the example code and have it read the text also.
