Hello,I have many old .tlogs created using mission planner, sometimes on linux and sometimes on windows, on various different computers. I've recently tried to review many of these old logs and found…Continue
How to tell if antenna is 433mhz or 915mhz?
Started this discussion. Last reply by Bill Bonney Apr 9. 3 Replies 0 Likes
Hi all,I have had both 433mhz and 915mhz 3dr radios and I'm worried I may be mixing up antennas.They are all the same size and shape, but some have a red dot sticker and some have a blue dot sticker.…Continue
3DR Radio bricked by failed firmware update

Hi all,I have a pair of 433mhz 3DR radios. One of them "lost sync" during a firmware upgrade. Now it has the red led on solid whenever it is plugged in, and all attempts to communicate with it…Continue
Ok to use the balance connector to get desired voltage?

I have seen many forum threads out there where someone wants a lower voltage than their battery supplies, and people on the forum suggest tapping into the balance connector to use fewer cells. I have…Continue

Aaron Curtis commented on Kevin Hester's blog post Droneshare now a standard part of Andropilot"Hi there. Is droneshare open source? I have been working on a similar project and would be interested in collaborating."
Bill Bonney replied to Aaron Curtis's discussion How to tell if antenna is 433mhz or 915mhz?"Mine didn't ship with stickers either. They where purchased last August.
Anyway, if you 3DR radio is or working as expected contact support help@3drobotics.com"

Bill Bonney replied to Aaron Curtis's discussion How to tell if antenna is 433mhz or 915mhz?"Red dot is for 915Mhz, Blue dot is for 433Mhz. :-D"
Aaron Curtis replied to Aaron Curtis's discussion 3DR Radio bricked by failed firmware update"Well, before, it was saying "could not identify radio" after trying a few things. But I just tried again, and it programmed the radio just fine! I think I may have an intermittent solder joint issue. I keep reflowing the joints but the…"
DeveloperAndrew Tridgell replied to Aaron Curtis's discussion 3DR Radio bricked by failed firmware update
"If the red led is on solid then it means it is already in bootloader mode, and is waiting for a new firmware. So the real question is why it doesn't come out of bootloader mode when you upload a firmware.
What happens when you try to upload a…"

Aaron Curtis posted a discussionOk to use the balance connector to get desired voltage?
I have seen many forum threads out there where someone wants a lower voltage than their battery supplies, and people on the forum suggest tapping into the balance connector to use fewer cells. I have an example right now-- I'm running a 4s battery but need to power a 12V transmitter, so I could just tap into 3 cells.Seems to me that by discharging the cells unevenly I risk damaging the battery. Is that so? If I balance it after flying each time will everything be OK?See More

Fun with FLIR (detective work on melting FPV goggles)
Posted on August 20, 2012 at 1:30pm 8 Comments 1 Like
I've started flying a lot of FPV recently, and I noticed that my Fat Shark Base glasses were getting quite hot after just minutes of use. Using my lab's handheld thermal infrared camera, I took some photos of the goggles and my quad after a few minutes in the air partially to try and troubleshoot the heat problem but…

Hi all,
It occurs to me that I never got around to posting my videos flying my ArduCopter, Cindi Lou, on Mt Erebus last December (2011). I'm at around 10700 ft, but the pressure altitude is around 0.65 bar -- the equivalent of closer to 13,000 ft at the equator. This was on a nice, warm (-15C) nearly windless day. I was pleasantly surprised how well the quad…
Continue Four ArduCopter flights in a row before crashing!
Posted on February 6, 2011 at 10:30pm 14 Comments 0 Likes
After a rough start last month, my ArduCopter CindiLou showed what she could do today. See the attached video for four flights. In the first three the camera is pointing at the Cindi, and in the fourth I have mounted the camera on the forward landing gear so you get to see a rather dramatic crash from the quadcopter's POV. The wind was blowing quite strongly to the…
Continue What to tighten and what not to: my first baby steps with my ArduCopter
Posted on January 19, 2011 at 10:00am 31 Comments 0 Likes
I've now gone around one full circle on the UAV wheel: I built her, flew her, and crashed her. It has been great fun so far and I can't wait to get in the air again. Before I do, however, I thought I would write something so that other beginners could learn from my mistakes.
Anticipation and Assembly
I decided sometime last April to buy an ArduCopter spent several months in breathless…
