LMRnet AKA LMR IoT (Internet of Things) Data Service

LMRnet AKA LMR IoT (Internet of Things) Data Service

Some days ago I saw in sparkfun news this particular one about their new Data Service (https://www.sparkfun.com/news/1527).
After that I asked Frits and Matt if we could host something similar on LMR's servers.

Prototyping CNC MkII

Late 2012 I started developing a 5 axis, CNC controller. The PCB was made but It was a long term project that ended up sitting on the back burners. I never had time to test it or write code. Although an Arm processor would be slightly cheaper and more powerful I have kept the design Arduino compatible as this is easier to hack for most hobbyist.
