CHIRIMEN is a development environment that allows to control the physical devices (such as sensors and actuators) only by Web browser technology and includes hardware (board computer) and software on it. Their implementation includes hardware as a board computer, Web browser software (currently using Boot to Gecko), and low-level device APIs (WebGPIO and WebI2C etc.) to control physical devices by web apps or JavaScript It is developed by CHIRIMEN Open Hardware community and code-named “CHIRIMEN”. Their hardware and software have been released as open source.
CHIRIMEN can operate the contents within a screen, and a real physical device only with the technique of a web browser altogether simultaneously.
Its hardware is an embeddable board computer with interfaces such as I2C and GPIO etc., and it assumes web browsers ) currently it is Boot to Gecko (B2G) ) as a prerequisite. The “CHIRIMEN Board Computer CMN2015-1” by the CHIRIMEN Open Hardware community is the first prototype hardware for CHIRIMEN.
Currently, it is Boot to Gecko (B2G) OS. It is not Firefox OS. It supports Boot to Gecko 2.5 currently. Refer to the following clause for the reason which is not Firefox OS.
Boot to Gecko and Firefox OS is the same in code. After fulfilling conditions, such as quality and security, only the product which has obtained the licensing of the brand from Mozilla can use the name of Firefox OS. On occasions when it uses it as OSS without brand licensing, it is Boot to Gecko (B2G).
The hardware of CHIRIMEN is designed on the assumption that a web browser or comfortable operation of Boot to Gecko. Since a browser requires comparatively high graphics performance, it is mainly the feature in contrast to other board computers. Therefore, SoC designed for a tablet or STB is carried.
CHIRIMEN can utilize a cheap and general-purpose sensors and actuators with GPIO or I2C interface. The correspondence to the device using SPI or UART is also considered. Of course, USB can be utilized as an interface for keyboards, pointing devices, and network adapters.
It was developed by the CHIRIMEN Open Hardware community. However, that community itself does not do manufacturing and selling of that.
Yes. However, assistance in particular of a software is not expectable from a community in that case.

Purchase may become possible if it is mass-produced by the licensed marker based on the released source code.
However, such a product has another product name from the constraint by the brand policy of CHIRIMEN. A viewing of “Based on CHIRIMEN technology” may be able to be seen for those products.

The community guarantees nothing about distribution of hardware. The CHIRIMEN Open Hardware community publishes only the source code of the hardware required for production of the CHIRIMEN, and the software by open source. However, they do not manufacture and sell hardwares. It may be sold when the company which manufactures and sells using the information on that open source appears. However, “CHIRIMEN” is not used by the CHIRIMEN license policy as such a product name that a certain company sells.

A CHIRIMEN Open Hardware community does not manufacture and sell CHIRIMEN.
CHIRIMEN was designed so that it can manufacture at a comparable or lower price point as the common board computer for prototypings.
They cannot do it without the grant from Mozilla Corporation.
WebDINO Japan is doing the intellectual property control of the source code as a substitute of the community. Refer to this information for a copyright and a license.
We should compare the definition of OSHW with CHIRIMEN License. There are many common points, but there may be some difference.
Both the design information for manufacturing a CHIRIMEN board-computer hardware and the source code of B2G OS software for it are contained in it.
A schematic, a print pattern (Gerber data), a partses layout, a parts list, etc. may be released. And, many of them are offered in the form of the electronic filing required for reproduce easily.
Anyone can manufacture it freely based on a license. However, “CHIRIMEN” cannot be used as a product name.But, it is possible without a prior authorization to carry out advertisement named “Based on CHIRIMEN technology”. Please refer to this license informtation for details.
Anyone can sell it based on this license. Please also refer to the preceding clause.
It is released to the public by the CHIRIMEN license which covers both a hardware and a software. Please refer to this.
No, it is not a product of Mozilla.
No. CHIRIMEN Open Hardware is not a project of Mozilla Corporation or Mozilla Foundation.
WebDINO Factory is the framework established as an environment for studying making ones by an open source. It was established under initiative of MJ in 2012. CHIRIMEN Open Hardware is the project currently promoted by the community in WebDINO Factory. Please have a look here for details.
In the future society where various physical things are connected through computer network, this project/community will be making suggestions on the identity of the Web as well as better relationship between human and physical things over the Web.Please have a look here for details.
CHIRIMEN is one of the development productses by a CHIRIMEN Open Hardware community. CHIRIMEN is not one carefully. The first products developed in 2015 is called design ID CMN2015-1. In the CHIRIMEN Open Hardware community, the development of the open hardware and software which used web browser technologies including CHIRIMEN as the base is carried out. Please refer to the preceding clause for the establishment aim of a CHIRIMEN Open Hardware project.
The information required in order to manufacture the board computer of the web browser base which a CHIRIMEN Open Hardware community advocates is released by the open source. It contains both the design information for manufacturing a CHIRIMEN board-computer hardware and the source code of B2G OS software for it are contained in it. Furthermore, not only a source code but a development, investigation of API, and the process of an discussion are made open.
Not only an individual but arbitrary organization and party can participate.
You can participate in CHIRIMEN Open Hardware community through the participate to CHIRIMEN Open Hardware Facebook Group, and CHIRIMEN Open Hardware slack.
