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.

Help with Beaglebone Black balancing robot

Hello everyone, I want to start by saying this question post might become long and I hope you guys hang on and are able to help me. So here we go :)

First of all the robot is barely able to balance. Here is a video of the robot trying to balance. The problem seems to be that the robot is not able to reach the setpoint fast enough. This is a speculation so you guys give me your ideas on what the problem is also.
