comment How to close color Sensor properly?
Yes, I got that part - I'm really asking if there's any more information on the error about where in your codebase the exception is being thrown - there are two possible lines that can throw that - in your pasted code these are lines 1 and 4 - I was hoping there would be stack trace (especially if this is happening on your Laptop rather than on the Brick).

Also - where are you seeing the error coming from - is it when you try and instantiate the EV3ColorSensor or when you instantiate the RemoteEV3? Both of these appear to be able to throw the error you're seeing. One other thing: according to this thread it might be more efficient to use the createSampleProvider method when dealing with remote bricks and sensors.

comment Can I build a faster LEGO train motor?
You also need to remember that there are really two scales at work with LEGO trains: One is the true "Minifigure" scale, and the other is the actual train build scale: Most real world trains are wide enough to fit two sets of two seats in a carriage (four people and an aisle), while LEGO trains barely manage 1 seat wide. The gauge of the track does not match the scale of the people.

comment What adhesive can bond LEGO bricks to metal?
It's a self answer - Amanda tried a couple of suggestions, but found that Araldite Rapid to be the best solution to the problem ;)

comment How can I remove permanent marker from a LEGO brick?
You need to be careful with Acetone though, as it will melt the ABS used to make the bricks if left for too long.

comment Mindstorms crashes when connecting to EV3 with Bluetooth
There appears to be a known issue with the Bluetooth stack in Yosemite. Until this is resolved, you won't be able to pair the EV3 with a Mac.
