Arduino troubleshooting request
« on: September 03, 2012, 01:28:12 PM »
I have to stop trying to fix this before i destroy anything else.

I have a promini problem, and now an IMU problem, and i would like some assistance determining what i need to send back to vendor as defective, what i have destroyed, and what still works.

basically my quadcopter just shut down mid flight, i determined that the flight controller (promini with shield and IMU) was no longer distributing power from the BEC connection, after scrutinizing my shield for trace breaks, i ordered a new promini.

new promini arrives with no pins, i buy pins, do my best soldering and i get to load my flight controller sketch and it goes haywire.

I dont know if my soldering sucks (probably) or i have a bad/destroyed arduino, or 2.

so i pull out my trusty dueminalove and protoshield and make my own flight controller, only i managed to accidently droop a bit of solder connecting ground to Vin where my IMU plugs in. so now my IMU turns on, but i get no communication. I assume i destroyed the built in LLC, but not sure how to fix that, IF its fixable. this thing is super tiny.

I live very close to Familab, but i work till 6 or 7 every night. Id really like to get this figured out, but have decided to stop playing with it until i figure out whats actually usable anymore, and if i need to send the second promini back to vender.
thanks,
Scot

I'd be glad to help you troubleshoot in person.  I don't know much about the promini but can give it a go.  If you need to lift some SMT parts I have a hot air pencil, too.  Evenings are best for me, too.

I'll be up at the lab on Saturday for our Intro to Soldering class.  Class runs 10-12pm so after that is good.

Just PSA: The class is 1-4pm, with RPi group at 6pm. :) We'll probably be there early though.

Thank you guys for the assist, we determined that my troubleshooting was basically correct, i had trashed all of my arduinos, but my IMU seemed functional. I ordered new promini and just got the pins soldered in place last night, loaded the sketch, and attached my IMU to my BoB.

connected to the GUI and everything seems functional, if out of calibration. i will finish assembling tonight, and hopefully get some flights int his weekend.

Thank you all very much for your help, i truly appreciate it. am going to be working with Thantik on some printing, so i may just have to get a membership!

having said that, apparently the issue is with my BoB, or my speed controllers. I am going to guess something is wrong with the BoB, i plugged everything in, and turned it on via ftdi cable like before, the only difference is the RX and the speed controllers are connected, and when i connected the GUI nothing worked, tried reloading the sketch and got that fatal arduino error, just like the last one. its shot, cant even load blink on it.

I figure i need to cut my losses on the board i am using, and go ahead and purchase a new flight controller all together, and im pretty bummed about it, but thats life.
