Luka Mustafa talk at VHS was inspiring! He talked about 3 different hardware products that he's been involved with. These were GoodenoughCNC inexpensive and Good Enough to get the job done CNC router, Safecast an environmental monitoring and Radiation Mapping tool and platform, and Koruza a Wireless Optical Communications platform!
All files, sources are on github
I've included some photos and comments below from his talk.
A bit about Luka.
Luka holding is The Wireless Optical Communications unit.
Interesting fact... They built a long tunnel and filled it with "fog" to do environmental testing. So unit will work not too badly in fog, rain, snow, smog etc. Also found out that buildings move a lot during the day/night as a result of thermal expansion contraction. Need to account for this in design.
Some of the Koruza development prototypes. Elements of the open source 3D printers made it into this design

Off Grid Solar Powered Safecast unit with self contained battery management system.

GoodEnoughCNC. The idea is just ship the essentials and let everything else be sourced locally. So CNC frame is made from steel bar which is available world wide. All files and designs are available on github.
I'm thinking we should build one of these for VHS.
ToslinCNC- Fibre optic cnc machine control system.

Goodenoughcnc hooked up to a plasma torch in Nepal.

System breakdown diagram. Interesting thing about this design is that all modules are optically isolated with optical fibre being used communicate between all modules.
All design files. board gerbers, etc can be found here on github .
Check this and all the other projects out if you have time!
