...well how bad was the corrosion? Citric acid is mainly used for dissolving rust (I had to look it up). I would shy away from using it on a pcb full strength. P.S. Acid and metal is not the best combo. A better solution (Jacked from ifixit) I personally use distilled water followed by a good isopropyl rinse (for pcb cleaning in general). I would get a wash bottle, and some anti-static brushes. Give your board a rinse down with the distilled water, agitate the surface of the pcb with your brush, rinse again, rinse with isopropyl, then let it dry (completely). This should help to remove any residual citric acid. See what others have to say, I'm just one cowboy *pew pew*

Hi, sorry your having problems, I'm going to suggest you watch this, start to finish. If you follow all the steps in the vid and it still doesn't work, let me know. Edit: maybe skip to the 7:00 marker.

Mk, ill byte, whats the application? After a bit of preliminarily research, I would focus on getting this to work, specifically the MPU6050_DMP6 demo. It may be a tad bit hard to follow, but as far as the acquisition of usable data, it looks like it should do everything (minus your velocity calculation, which I'm not entirely convinced ya need). I wouldn't even worry about the motors yet. From what I was able to gather, out of the box it gives you yaw, pitch and roll in degrees. Assuming this is part of a drone, you should be able to do some very useful things with those values. I might be missing something, but if you have your pitch in degrees, any change in pitch (delta pitch) could be divided by time, giving you a degree per second change in your pitch... right? map that to your second servo. The MPU6050 in the above code is set up to trigger an ISR (interrupt service routine) at a regular interval to grab the data from the MPU (I'm pretty sure), so that would be your time. (0deg - 2deg)/100ms (crappy example) -20 deg/s? depending on how many steps/degree your stepper motor is... (losses train of thought) I'm sure you see where I was going. Here's a list of stuff I was reading that might help. Any additional information you could provide might help. Let me know if this helped or just pissed ya off, ill be around.

Whats the other side of the board look like? see if you can pop it out, try removing the plastic knob on the front of the meter (carefully). For future the fuse is 20mm, 200V, 200mA Here is what I have been able to gather so far. based on the ME-550, it looks like the only thing holding it together is the range selector knob. Seeing as how close the batteries sit to the IC cutout (I labeled it wrong in the pic, not a uC) (see image below), there could be corrosion on the chip pins. The display could have also been affected by something. The traces are underneath, never hurts to take a look. There's a good possibility something 'shit the bed', leaky caps? dead chips? cooked resistors?, dirty pots?, hosed display?, lose wire?
