Welcome to Hello “Real” WorldCHIRIMEN Open Hardware

Community

Written by akihiko.kigure

What is CHIRIMEN?CHIRIMEN is a development environment that

allows to control the physical devices (e.g. sensors, actuators) only by Web browser technology and

includes hardware (board computer) and software on it.

History of Name “CHIRIMEN”

The two different worlds

“Web” and “Real” are interwoven,

and then the New Real World

will be created.

“Web”

“Real”

The Goal of the Community is:1. to develop methods in order to control Hardware devices only by Web technologies

All by Web Technologiesby HTML, JavaScript, CSS

HDMI

sensors and actuators

I2C, UARTGPIO, SPI, PWM

The Goal of the Community is:2. to apply ideas of Web-based OSS to Hardware devices (including board computers)

For Example: Board Case

The Goal of the Community is:3. to inform the above-mentioned two items to many people (through education, demonstration, etc.) 

Work Shop, Exhibition, etc...

Feature 1: Everything controlled by Webapps

• Web engine(B2G) on which everything can be controlled by Webapps is equipped.• Low level web

interfaces(webGPIO,webI2C) to directly control various devices by Webapps are equipped.• HDMI Connector to output rich Web

contents and Hi-speed CPU/GPU are equipped.

Feature 2:Easy stand by Development Environments

• A Web development environment can be used just as it is.

• Web Application can be developed by a Web development environment equipped in Firefox Browser. And application will be able to uploaded.

• Need NOT Compile. Try & Error very easily.

Feature 3:Open Source Hardware

• All the information(Firmware, Circuit Diagram, Board Plan, Parts List, Discussion) is disclosed as “Open Source”.
