If you are affiliated with mindsensors, it seems slightly disingenuous to refer to yourself/your team as a third party without a stake in the game. This is especially true when it comes to endorsement of a new product that serves a critical role and has no competition heritage.

I am in no way accusing you of not doing due diligence or appropriate testing, or questioning your results, but I think it's important for teams to know whether testimony they are basing their purchasing decisions on is coming from an end user or essentially from the inventor(s)/vendor.
Just to share - I have nothing to do with MindSensors or their team.
I merely like the idea of competition for the pricing of FRC motor controls.
It's easy to go back through my post history to show that I have built other controls in the past and expressed public interest in the matter on this forum.

To be fair I also bought 2 Sparks as well.
This is not a Team 11 thing either.
It's just little old me being curious.
I have my own parts to build FRC robots so I don't have to impact Team 11 or 193 operations to do this.
I also have my own machine tools.

At the moment I am planning on doing the temperature and current measurements with an Arduino based data logger but I have more development boards than I care to discuss so I could do this with something more powerful. I will likely use a Dallas 18B20 for the temperature measurement with it installed in a steel cartridge in direct contact with the ESC heatsink and a either a TI or Maxim chip for the current measurement using a current sense resistor of a value I will disclose. It's likely the current sense resistor will be less than 1mOhm right now. I need to disclose that because it has a slight impact on the motor circuit.
