Your ambient temp seems to high -> minera shows 143 degree Fahrenheit
That's the temp of the laptop itself though, not the miner sticks. It runs hot, always has. I think it's a Sony thing. The fan is barely going and it will sometimes get up near 200+ degrees and sounds like a jet engine when I'm running a bunch of stuff on it. Had it for 3+ years though and no problems with CPU or GPU and I use to do windows 7 development on it, and anything microsoft is a resource hog.
Honestly get a RPI and you will be so thankful. You don't need a ton of power off a machine and could save your laptop some stress of really hot.. that does not sound good.
But you could even use minera on RPI. For a little investment your power cost vs a laptop will be decent. And RPI's are pretty cheap. I highly suggest getting one vs your laptop.
And very cool to see the pod in the works. Thanks for keeping us in the loop I love watching your dev process.
