E-Flight Apprentice - Maiden Voyage

Started May 9, 2011 0 Replies

First of all, thank you, thank you, thank you! This is just the type of project I can sink my teeth into. After reading Wired's article on the Arduino, I went and bought the MegaPilot kit, soldered…Continue

Process Control Tutorial

After reading about cascading PID controllers in the ArduPilot manual, I decide to learn a little more about controls and control systems. I came across this very informative site and thought it…Continue

CarbonCore Cortex by Autonomous Avionics

 Autonomous Avionics is proud to annouce their latest ready-to-fly X8 octocopter. The CarbonCore Cortex folding airframe is an 800mm coaxial carbon fiber airframe loaded with a 3D Robotics Pixhawk flight controller. The 8 MN4120 T-Motors are more than adequate for carrying a full frame DSLR camera and 3-Axis gimbal. Each…See More

"I love it! Great flying airframe and have happy with the results so far. I have recently upgraded to the Pixhawk and it is amazing. I have mounted a gimbal and a set of larger landing gear since I posted these photos and I currently fly a Sony NEX 5…"

"Hi Bernie, How's your quad flying? I've got a similar setup using the same motors but flying 2x 6s packs. Today I flew without payload and got 29 minutes of flying... Just curious to hear what you think of the Quad frame you have and how…"

"I like what you are doing, there is not a fully loaded Arducopter PDB type of board anywhere bar hacking your own, Good work!"

"I fly the APM 2.6 and use 6s batteries. That was certainly a factor in designing this. I also believe something the flies shouldn't have parts that dangle. I solder all the connectors I can after experiencing a mid-flight mechanical due to a…"

"Re: Current sensor - the new immersionrc version for the ezOSD now supports 6S. I found it to be a more elegant waz of Current Sensing, as I was going to use immersionrc for the FPV kit anyway. I also have the spektrum current sensor (easy to run…"

"I approached it differently...I designed the frame around the Gryphon, BEC disc and all. :-) It's a beautiful bit of kit, but for the life of me, I'll never work out why they figured we needed 4 x 12V BEC outputs, and only 2x 5V."

Guy McCaldin commented on Bernie Hoffman's blog post Power Distribution Board
"The Gryphon is a really nice board, and where I've got a lot of my inspiration from.  The downside is that it's rather massive (100mm diameter), which doesn't fit into my frame, and they're asking $89 extra for the Power…"

"By chance, I started working on the same problem yesterday after not being able to find anything suitable on the market.  Integrating the current and voltage sensor is a neat idea I hadn't thought of.  The option for 5V and 12V…"

"Here is a low cost prototype PCB option: http://www.seeedstudio.com/depot/fusion-pcb-service-2-layers-p-835.html?cPath=70_71 The main problem is that they just produce 1 oz PCBs (0.03mm copper thickness), and you want a 2oz PCB to handle that kind…"

Power Distribution Board

After putting together a Carbon Core 950 and trying to fit all the electronics, ECSs and miscellaneous electronics into the frame, I realized I really need to use a power distribution board to keep the installation clean. I know there are some pretty good power distribution boards available, but none that did what I…See More

"Finally was able to get more information. The total flying weight is right around 3200 grams (a little over 7 lbs) The total current draw at hover in no wind was measured at 17 amps or 425 watts (17 amps x approx. 25 volts) I am using these motors…"

"Hi, What is the total AUW with the battery and everything on board ? Why did you choose this motor in particular ? What is the total current consumption at hover that you measure ?   Thx"

"Very nice looking installation. I like your combination of O-ring and Foam Earplug damping method. The reason you needed the ear plugs is because of the extra clearance between the O-ring suspension points, closer coupled ones don't have so…"
