+===== BLE Chorder Feb. 2016 =====
+I have been using a chorder built using the [[https://learn.adafruit.com/adafruit-feather-32u4-bluefruit-le/overview|Adafruit Feather 32u4 Bluefruit LE]].  This board has the LiPo charger and BLE transceiver built in, so all that is required is attaching the keys, an on/off switch, plugging in the battery and programming it (over a standard micro usb cable).  I will post a schematic shortly, but in the mean time, here is the link to the github source:

+Spaceman Spiff's Chording Keyboard Experiment is based on the HIDkeys
+application of Objective Development Software GmbH, and their
+distributed AVR-USB firmware only driver. The directory usbdrv
+contains the driver and available license etc. in unmodified form.
+The license for the USB driver requests full disclosure of circuit
+diagrams and source code, and while other licences are possible,
+the additional requirements of requiring redistribution of any
+derivative work is not only acceptable, but highly appreciated. The
+remaining parts of this project will therefore be published under
+the same license, which is listed below for reference.
+Hopefully this will allow further development of applications based
+on the AVR-USB driver, and inspire others to share their work in a
+similar fashion.
+The OBDEV license is listed below.
+PREFACE
+Conceiving and understanding a new license is not an easy task. To make things
+easier for both, the author and the licensee, we have decided to base our
+license for the USB driver on an existing license with well-understood
+properties.
+Our favorite choice for the base license was the GNU General Public License
+(GPL). However, we cannot use the GNU GPL directly for the following reasons:
+(1) It was not intended for projects involving hardware -- we must extend the
+    term "source code" to at least the circuit diagram.
+(2) The GNU GPL does not require publication. Only if a binary is published,
+    it requires that the source is published as well. This is reasonable for
+    software because unpublished software is of little relevance. For projects
+    involving hardware, we want to REQUIRE publication. More than that, we
+    even want to define HOW the publication must be done (files contained,
+    file formats etc).
+(3) As the author of the software, we can distribute it under more than one
+    license. For people who don't want to meet the obligations of the GNU GPL,
+    we want to offer commercial licenses. To avoid a split in revisions of
+    the driver, we need special privileges to distribute contributed
+    modifications under proprietary licenses.
+We can not simply modify the GNU GPL and incorporate our changes because the
+Free Software Foundation (FSF) who holds the copyright for the text of the
+GNU GPL does not allow modifications. We therefore set up our own small
+license which incorporates the GNU GPL by reference:
+LICENSE FOR PROJECTS BUILT WITH "OBJECTIVE DEVELOPMENT'S
+FIRMWARE-ONLY USB-DRIVER FOR ATMEL'S AVR MICROCONTROLLERS"
+Version 2006-01
+I. Definitions
+"OBDEV" shall mean OBJECTIVE DEVELOPMENT Software GmbH or any legal successor
+thereof.
+"Software Source Code" shall mean the preferred form of the software for
+making modifications to it.
+"USB Driver" shall mean the Software Source Code for OBDEV's firmware-only
+USB-driver for Atmel's AVR microcontrollers.
+"Function" shall mean the Software Source Code for all software executed on
+the microcontroller except the USB Driver.
+"Host Software" shall mean the Software Source Code for all software required
+to control the USB device from the USB host running any operating system.
+"Project" shall mean the USB Driver, the Function, the Host Software, circuit
+diagrams of the controller based hardware and accompanying documentation.
+"source code" shall have the same meaning as the term "Project" above.
+"Web Site" shall mean a collection of text and multimedia documents accessible
+worldwide over internet through the HyperText Transfer Protocol (HTTP) on
+TCP port 80 (standard HTTP port).
+II. General License Terms
+The general terms of this license consist of the GNU General Public License
+Version 2 (GNU GPL2) which is hereby incorporated into this section as though
+it were fully set forth here. A copy of the GNU GPL2 is included for your
+convenience in appendix A of this license.
+The term "source code" in the GNU GPL2 is to be understood as defined in
+section I above. If any term or definition in section I, III, IV or V
+conflicts with the GNU GPL2, the term or definition in section I, III, IV or
+V has precedence of the GNU GPL2.
+III. Distribution of the Project
+The distributed form of a Project must contain at least the following files:
+(a) Software Source Code files for the USB Driver, the Function and the Host
+    Software.
+(b) Circuit diagrams for the hardware in PDF, PNG or GIF image file format.
+(c) A file with name "Readme.txt" in ASCII format with at least the following
+    content (in English language):
+    - An explanation what the Project does.
+    - What to do with the distributed files (installation procedure etc.).
+    - A reference to Objective Development's USB driver.
+    - Your (author's) name and contact information. E-mail and/or URL is
+      sufficient.
+(d) Optionally a text file with a description of the circuit diagram, an
+    explanation of special (software) techniques used etc.
+(e) A copy of this license in a file with the name "License.txt". This copy
+    can be in the "usbdrv" subdirectory which contains the driver.
+IV. Requirement for Publication
+All modifications and derived work (Projects using the USB Driver) MUST be
+distributed (published) as described in section III above on a Web Site. The
+main page must reproduce at least a description of the Project (e.g. as
+contained in the "Readme.txt" file distributed) and a download link for the
+entire Project. The URL of the main page must be submitted to OBDEV. OBDEV
+will provide a mechanism for submitting Project URLs and for publishing
+Projects on their Web Site. The Project must remain available for at least
+twelve (12) months after the initial publication or at least six (6) months
+after a subsequent version of that particular Project has been published.
+V. Author Privileges
+OBDEV reserves the right to distribute the USB Driver and all modified
+versions under other (proprietary) licenses. If you modify the USB Driver
+under the grants of this license, you therefore grant OBDEV (in addition to
+the grants of the GNU GPL2) a worldwide, perpetual, irrevocable royalty free
+license for your modifications. OBDEV shall not automatically gain rights
+other than those of the GNU GPL2 in the other parts of the Project. This
+section V overrides possibly contradicting terms in the GNU GPL2 referenced
+in section II.
+APPENDIX A
+                    GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+                            Preamble
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+  The precise terms and conditions for copying, distribution and
+modification follow.
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+and 2 above on a medium customarily used for software interchange; or,
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+                            NO WARRANTY
+. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+                     END OF TERMS AND CONDITIONS
+            How to Apply These Terms to Your New Programs
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+Also add information on how to contact you by electronic and paper mail.
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.
