Wow, this is awesome. I’m currently a MechE student, with a side interest in programming/electronics/mechatronics, so it’s really cool to see things like this combining all of those different areas in a way that can solve a very tangible problem. I look forward to seeing more videos and designs of these types of things as they are made! It’s really an inspiration to keep going with the studies.

So I’ve been using these, and normally they work fine, but recently, they have started shorting on me. They’ll be working fine, then all of a sudden, I’ll resupply power and nothing will work. If I remove the the MMA8452, everything else works. Then when I test the pins on the actual breakout using a multimeter (with it removed from the breadboard I am using), there is continuity between VCC and GND. I am running everything off of a 9v battery plugged into the RAW pin of an 3.3v Arduino Pro Mini, which properly regulates down to 3.3v as expected (verified with multimeter). I can swap in a different MMA8452 and everything works again. I have soldered standard straight pin headers to all of the breakouts, but I can’t imagine that that is the issue, since it only happens after using the accelerometer for a little while, so I don’t think it is a solder bridging issue, but I suppose it could be.
Any ideas as to what might be happening? Is there anything that might cause a working PCB to short, or did I just get unlucky with the manufacturing? I would like to be able to fix anything that I can, since I’ve already killed 2 and only have 1 left to work with, and I would rather not buy more if the issue is going to keep happening.

That’s what I’d do. Using the SDFatLib to create CSV files is really easy. Wire it up to pins D10-13 on the Pro Mini and you’re good to go as far as wiring. The only thing I see that’s wrong is that it might not be hard enough to seem fancy?
No public wish lists :(
