1. Copyleft Hardware
a new way to enjoy hardware, follow...

3. reverse engineering, anti-
vendor ports, begging for
datasheets - WHY?

Ben NanoNote
⁄ let's build our own computers, the right way
from day 1
⁄ without proprietary tricks, without NDAs,
trade secrets, patents
⁄ copyleft plans (CC-BY-SA), copyleft
software (GPL), patent-free

4. copyleft hardware is a new movement
⁄ mid-90's: free software (Linux)
⁄ last 10 years: free content (Wikipedia)
⁄ last few years: copyleft hardware (Qi hardware)

5. technology transfer
⁄ manufacturing process
⁄ how multiple companies and service
providers can work together
⁄ respect the work of others, find own business
opportunities
⁄ build ability to service the equipment
⁄ knowledge about PCB routing: EMI, noise, etc.
⁄ circuit knowledge: decoupling capacitors,
inductors, etc.

6. David Reyes Samblas Martinez
Tuxbrain
⁄ VCs, banks, academia, parents, incubators all
fail us, so let's do it ourselves
⁄ who's on board now: many individuals, Elphel
(USA), IDA Systems (India), Sharism (Hong
Kong), Tuxbrain (Spain)
⁄ largest company has 4 employees
⁄ university professor: Carlos Camargo, UNAL

7. ⁄ related projects: Milkymist
(GPL licensed CPU),
OpenWrt, JLiMe, KiCad,
gEDA, Icarus Verilog,
gtkwave, RTKLIB (GPL
licensed GPS stack),
OsmocomBB (GPL
licensed GSM stack),
HeeksCAD, gta02-core,
OpenMotic, Elphel (GPL

8. remember forks?
Forks in free software mostly fail, but their
presence keeps people honest, makes
them communicate, understand each other,
and want to find a way forward together.
Copyleft hardware brings the positive
power of forking to the hardware industry.

9. Terminology: too many people latch onto open
hardware, open source hardware, open design
hardware. We think copyleft hardware makes it clear.
copyleft: “the practice of using copyright law to offer the
right to distribute copies and modified versions of a
work” (source: wikipedia.org)

10. Ben NanoNote
⁄ ultra-mobile clamshell pocket computer, 126 g
⁄ no USB Host, no Wi-Fi/Bluetooth/RF, no touch screen
⁄ clean 2.6.34 Linux kernel, no binary modules
⁄ kernel patches in process of being upstreamed
⁄ full support in OpenWrt and JLiMe upstream
⁄ extensible over USB client cable
and SDIO-capable microSD
⁄ started selling in February, sold
800 to date in over 30 countries
⁄ 99 USD, http://nanonote.cc

11. SAKC
⁄ basically a Ben NanoNote
for hardware hackers
⁄ FPGA added, keyboard
and case removed
⁄ large software commonality
with Ben NanoNote
⁄ could be interesting for academia and hobbyists
⁄ led by UNAL and Carlos Camargo
⁄ currently only 10 SAKC boards exist, maybe
more for next semester
⁄ other universities need to join

12. How about later?

13. The End
— copyleft hardware: innovate, share
