Yet Another Build Log (YABL) - Part 1 - Reducing Arducopter vibration

Hiya, folks!

First of all, if you're sick and tired of looking at Arducopter official frame builds, you might decide to skip the whole post right about now ;)



Yes, it really is going to be just another ArduCopter build (my first quad, actually), but i hope people doing the same can learn from some of my mistakes and, perhaps, avoid them. So let's get on with the show, shall we...



Since i've been having some pretty nasty vibration issues with a traditional heli i've been… Continue

KK multicopter

Hi, I've made a Quad X copter using KK Multicopter blue board v4.5 (ofcourse I waited for 15 days to receive the board after placing the order). But mine is not going up. Its rotating on the ground. I don't what the problem is.... I've tried and tweaked as much as I can do by referring many sites. Also build 4 frames. But in vain. Its been two weeks I'm trying to make it fly.

 

I've used 

1450kv outrunner brushless motors

12A BEC Esc

Arduino use is exploding, thanks to its huge community

One of the best decisions we made was basing our autopilot system on Arduino (credit goes to Jordi for spotting its potential so early and selling me on it). The engineers all sniffed at it, complaining that it was just an 8-bit processor running at 16Mhz and could never compete with 32-bit ARM processors running at 70Mhz and faster. But what Jordi spotted was something more:…

How to read PPM stream and PWM pulses on sound card oscilloscope

 

Hi,

trying to help a developer (Ben Levitt) to track down a bug on my UavDevBoard system, it was hard to explain by email the strange behavior.

After he suggested me to try with a sound card oscilloscope, I decided to try something I was planning from sometime now : a soundcard oscilloscope.

I build a voltage divider to scale down PWM…

Rfm22 telemetry link, MS5706 , and new android software

Hello,

here is the last news of my development.

 

I received my small 5dof imu, some new sample of the last 24bits integrated pressure sensor from intersema MS5706, I plug everything on my RC receiver and telemetry transmitter and look at what will work... Surprisingly .. everything...

 

I check the range out of my telemetry board with just a crap antenna, and it is…

Stop motion excitement & LCD drivers

Got some high speed photographs of Marcy 1 spinning at flight speed, to see if the actuator & the wing did anything.   A slow motion video cam would be nice.
