"John, I'm not an electronics expert by far, so please don't hold me to my suggestions here.
I do a bit of hobby electronics. I make my own simple circuit boards and projects.
As you suggested, you could still use your ESC power output to…"

Hi everyone.I'm planning on a quad build with the APM2. I'v done some arduino projects but still quite green in the arduino field.I'd like to design a very capable lighting system for the quad as I…Continue

TJ replied to Nguyen Ha Minh's discussion APM2.0 output power rail stopped working"All I know is they offered to repair if possible or replace the APM2.
I'm no electronics expert, but I wonder if the diode is absolutely required, if it can be replaced with a higher capacity part, or if this is a run of bad diodes from the…"
TJ replied to Nguyen Ha Minh's discussion APM2.0 output power rail stopped working"Tsahi, Try powering the board from the input rail or there is a 5V/GND between the UART headers.

TJ replied to Nguyen Ha Minh's discussion APM2.0 output power rail stopped working"I contacted 3DRobotics in regards to this problem. They also said to ship the board back to them for repair or replacement. I have done so. They don't have any idea how long this process might take :( At least they're trying I guess."

Vernon Barry suggest consumers are shorting the APM2's out. I merely connected my battery with correct polarity as always. :("
TJ replied to Nguyen Ha Minh's discussion APM2.0 output power rail stopped working"My APM2 suddenly stopped working too from Output power rail. If I power it from the 5v/Gnd between the serial connection header pins, it powers up, though have not attempted to fly connected this way. USB power works fine. The only attached external…"
TJ replied to Marc's discussion Material"Marc,
Right, FR-4. I haven't started building yet. I'm ordering my first batch of parts in a week. I'll stay subscribed here for yours and others thoughts as well. I'm wanting to reduce the wiring and integrate it into the…"
TJ replied to Marc's discussion Material" I haven't tried it YET. But its the thought I'm running with. (found small air frame quads constructed like this)
I'm planning on using copper clad PCB for the entire airframe. Obviously etching off the copper to save weight,…"
TJ posted a status"can someone post up some telemetry data from APM2? I'm working on a lighting project and need to have an example of the data stream."
TJ replied to TJ's discussion Arduino pro mini (as light controller / experiment platform) piggyback on APM2."After some further research I'v decided to use the ATtiny85 microcontroller for each bank of LEDs.
I'v also order up some RGB strip from tayda electronics. They're in a waterproof package, we'll see how heavy it is.…"

Hi everyone.I'm planning on a quad build with the APM2. I'v done some arduino projects but still quite green in the arduino field.I'd like to design a very capable lighting system for the quad as I intend to eventually get some night flying in. Not to mention the cool factor of nice lighting. I'm interested in some cosmetic lighting options but really want to focus on some functional and informational lighting aspects.Some might include the copter orientation, accent/decent/hover indication,…See More

OK everyone, I'm really going to need all your expert advice.I'v decided to start on a quadcopter project.I love what DIYDRONES has brought to the table. I'm a linux user and believe in the open source community. I love to see the world work together toward a common goal.So let me start with what I want to achieve in my project. I'v decided on a "X" quad configuration. It just seems to me a quad would be more efficient than a 6 or 8 motor design. Maybe one of those would be good if one wanted…See More
