initial solar mesh router


News

So, after finishing version 1 of the solar mesh router in December 2006 - which is based on a gumstix.com board (for now), me and Stefan worked on version 2 now.

Stefan's experience and skill in assembly were invaluable. 

Version 2 is a much more solid design and points the way to future enhancements.


Overview

The version 2 of the solar mesh router (SMR) is a gumstix board with openwrt, linux 2.6 kernel and olsrd 0.5.5. It has a small but neat IP autoconfig mechanism and will scan for networks and attach to any mesh network it finds.

The very nice thing about it is that you will be able to place it 
anywhere and naturally it will run .




The right picture shows a complete set. With solar panel and assembly box. Currently everything (batteries + charge controller + mesh router) is mounted in one single toolbox for easier assembly, testing and carrying.

Still have to work on making everything waterproof.




Power requirements

Currently the version 2 runs on 3 Watts. Which is still far to much!
I talked with Bruce from greenwifi and seems like he found a way to go down to 1 Watt on a linksys. Which is massively impressive.  I hope there will be some cooperation possible in the future.


Future

  • Lower power requriements! This will be absolut key to any success. 
  • version 3: create a waterproof enclosure
  • testing in rough terrain
