-[[http://​www.obdev.at/​|Objective Development'​s]] [[http://​www.obdev.at/​products/​avrusb/​index.html|AVR USB]] driver ​is a firmware-only implementation ​of the low speed USB standard (USB 1.1) which can be used on cheap [[http://​atmel.com/​products/​AVR/​|AVR]] microcontrollers from [[http://​atmel.com/​|Atmel]].  +A chording keyboard or [[wp>​Chorded keyboard]] is an input device where characters can be typed by pressing multiple keys at the same time. A popular design is the 7-key chorder, where one key is used for each of the index finger, middle finger, ring finger and pinky, and 3 keys for the thumbThis can be used with either the left or right hand (or a chorder can be used for each hand, increasing typing speed). The current incarnation of the SpiffChorder ​is a 7-key chorder, although because ​of the easily changeable chord-maps, fewer keys can be used as wellThe hardware-design has been designed for chords consisting of up to 8 keys, plus 3 additional keys that can be used as modifiers (ctrl, alt, shift)This allows substantially different chording ideas to be implemented,​ such as the [[Twidlette]]. 
-The hardware for the SpiffChorder ​is very simple, ​and consists mainly of an ATmega8, a 12MHz crystal, and a few passive components for interfacing with the USB portApart from this 7 switches are connected, and optionally 3 LEDs for indicating ​the internal state.+Both the hardware ​design and software/​firmware ​for the SpiffChorder ​are open.  You can make modifications as you see fit. The license was based on [[http://​www.obdev.at/​products/​avrusb/​license.html|Objective Development'​s license]] ​and can be found in the 0.98 release. With the 0.99 release it was changed to [[http://​www.gnu.org/​licenses/​gpl-3.0.en.html|GPLv3]].
-Additional information is available ​at [[http://symlink.dk/projects/spiffchorder/]], but this is slightly outdated.+[[http://​www.obdev.at/|Objective Development'​s]] ​[[http://www.obdev.at/products/avrusb/index.html|AVR USB]] driver ​is a firmware-only implementation of the low speed USB standard (1.5Mbps) which can be used on cheap [[http://​atmel.com/​products/​AVR/​|AVR]] microcontrollers from [[http://​atmel.com/​|Atmel]] 
 +The [[hardware]] for the SpiffChorder is very simple, and consists mainly of an ATmega168, a 12MHz crystal, and a few passive components for interfacing with the USB port. Apart from this 7 switches are connected, and optionally 3 LEDs for indicating the internal state. The SpiffChorder originally used an ATmega8, but due to the limited flash memory in these devices (in particular when also using a boot loader), it was decided to aim for the ATmega168 instead, which is only slightly more expensive, and apart from the extra flash memory also has port-change interrupts, which will be a benefit when implementing pointing device support.
 +The project page can be found at [[http://​symlink.dk/​projects/​spiffchorder/​]],​ but this wiki will contain more updated information and more specific information,​ especially when it comes to the documentation of the project.
 +The SpiffChorder is up to the task of daily use as a primary keyboard. ​  It has been in use as such since 
 +October of 2007.  The current build was released in March of 2008 and currently serves as the input system on wearable computers, in-car computers, palmtops, laptops and desktops. ​ Folks type on their SpiffChorders while running, walking, riding, sitting, standing and lying down.  We have heard from people around the world who have built and use Spiffchorders,​ sometimes as their first electronics project.  ​
 +If you build one or want to build one, please let us know.
