I have my APM1 based UAV working now, it's been quite a journey so I thought I would post some of what I learned since many others are probably going to be buying APM1 now that it's half price (right…Continue

Wondering if anyone else has seen this problem. I followed the instructions on enabling the built-in battery monitoring for APM1 (I have APM 1.4), soldered the leads to the board and soldered in the…Continue

Gary Hethcoat left a comment for Will Hansen"Hi Will,
My company does large volume residential. Unfortunately I am too busy making a living to pursue the UAV-based roof survey idea right now. I'm hoping that will change in the not-too-distant future. I'm trying to…"
Gary Hethcoat replied to Gary Hethcoat's discussion APM1 - ArduPilot Mega and Mission Planner for Dummies"Thanks Tim. If I can save a few people some of the frustration I went through, it will be well worth it. A lot of people helped me, so just trying to give back a little.

I have my APM1 based UAV working now, it's been quite a journey so I thought I would post some of what I learned since many others are probably going to be buying APM1 now that it's half price (right after I bought mine of course :-)I'm writing this since I know many of you are not very experienced with R/C, let alone something like APM. The wiki instructions are well written and helpful, but they may lack details needed by people with little experience.First lesson is, be very careful what…See More
Gary Hethcoat replied to Rigel's discussion Battery monitoring causing APM eratic behavior"Which version of APM are you using? I've posted my experience with APM1.4 and the on-board battery monitoring.
It *does* seem to cause some issues, but mine are different from yours."
Gary Hethcoat replied to Gary Hethcoat's discussion On enabling battery monitor on APM1, autopilot stopped working"After more experiments, I've concluded that the APM1.4 board that I have will not power up and initialize correctly with the battery monitor circuit connected. At least not consistently. If I leave the battery monitor circuit…"
Gary Hethcoat replied to Gary Hethcoat's discussion On enabling battery monitor on APM1, autopilot stopped working"Hi Jasper,
Thanks, you were right. After re-calibrating my R/C, stabilize once more is deflecting the servos. After flight testing I'll report back to confirm everything is OK. I did download an MP s/w update, maybe that nuked…"
Jesper Rooth replied to Gary Hethcoat's discussion On enabling battery monitor on APM1, autopilot stopped working"Check RC* settings. Maybe you lost configuration for your radio. Re-setup radio and check."
Gary Hethcoat posted a discussionOn enabling battery monitor on APM1, autopilot stopped working
Wondering if anyone else has seen this problem. I followed the instructions on enabling the built-in battery monitoring for APM1 (I have APM 1.4), soldered the leads to the board and soldered in the single resistor where indicated, checked all connections carefully. Did the calibration as instructed, turned everything on and the voltage monitor worked, voltage reads out fine in the MP over telemetry. It's about 0.3v high, but otherwise fine. I neglected to re-check everything else…See More
Gary Hethcoat replied to John OBrien's discussion 3DR Radios working - what's next?"OK, I nominate myself for "dummy of the week" award :-) I had the connector reversed on the air side. I was mostly paying attention to the +5v line, which is of course in the center :-( Everything is working…"
Gary Hethcoat replied to John OBrien's discussion 3DR Radios working - what's next?"I have not used xbees, this is my first attempt at telemetry. BTW, I was quite happy to get the basic autopilot tuned and working last weekend. Appreciate the help from everyone.
Chris, thanks for the response. I'll check out…"
Gary Hethcoat replied to John OBrien's discussion 3DR Radios working - what's next?"I'm seeing the same thing as John. The radios appear to be working fine, the config interface loads the data and works fine. It just won't connect (times out). The USB is disconnected.
I'm using APM 1.4 with the…"
