DISCLAIMER: This could be dangerous and might crash your copter.
OK! I made some new changes to the autotuning algorithm and I have tested it again in the simulator. I think this is ready for some real world testing from some VERY BRAVE users, or some simulation testing. Unfortunately I do not own a quad and my octo is out of commission until Tuesday, or I would be testing this right now outside.
FPV is the greatest way to discover places while you're on vacation. In the next few weeks and months TBS is going to present a couple of vacation videos ... here's the first from the Maldives, piloted by RiSCyD.
If you have quite a wedge of loose change down the back of the sofa this might be a fun thing to purchase!

First, THIS IS EXPERIMENTAL FOR SIMULATION ONLY. Video coming shortly of me using it in the simulator.
I have a functional first attempt at automatic P gain tuning. I'm calling it Pretty Good Gains (pun intended). There is definitely room for improvement, but here is how it works:
PID controllers usually end up with an output graph that looks something like this (from…Continue
A professor at MIT developed an equation to determine the fastest theoretical air-speed for obstacle avoidance.

I typed in Quad Copters and girls and this is what came up.

The same group (http://grassrootsmapping.org) which organized a citizen mapping of the BP oil spill is offering their DIY balloon-mapping kit as a reward in their Kickstarter campaign, which ends on January 30th. Having formed an DIY, open-source environmental science movement called Public…Continue
Here is a good example of collaboration, an Hybrid MultiCopter.
This is my first blog here so just few words about me: I’m an electronic engineer, I'm from Romania and my hobby is obvious.
By more than one year now, I spent lot of time working with Atmel XMEGA family. My first autopilot with XMEGA 128A1 had external 16bit ADC (ADS8344) because at that time, internal 12bit ADC and DMA were still unclear to me. MPX pressure sensors for air speed and altitude, HMC5843 compass, ADXRS610 gyros and LIS344 accelerometer.…Continue
Quad is made from a combo of fusion plastics and carbon fibre.
This is a parts and build video of the frame
i will be continuing to test this frame out crashing it dropping it and other crazy flying mishaps that happan when you fly quads.
this frame is only for the open source community
JETPAX want to give back to the open source developer with this great durable
Here a video about the HIL tests of the firmware ArduCopter v2.2 b2xp2 (with JLN updates) with an Helicopter in H1 mode (Raptor 30 type) on the AeroSIM-RC simulator.
The tested features are:
- STABILIZE mode,
- LOITER mode (GPS position Hold),
- RTL (Return To Launch),
- AUTO mode (GPS…
A fun video to watch.
I changed the attitude control loop a little bit to achieve more stability. Rate control with a PID(T1) instead of a PI controller. Here I present the necessary changes in the code to do this.
DISCLAIMER: I hope I do not bend the forum rules too much by this blog post and would hate to offend the community by starting the discussion of a (at least marginally) political topic. However, since in the past also UAV regulatory developments and issues that relate to the…Continue
It would seem over time this little community is picking up in notoriety. This is awesome everyone and the growing numbers and increased projects and creativeness show what a truly unique community we have here at DIYDrones. Keep it up and I am sure that we will continue to gather more press. The link to the article can be found at:…Continue
ArduPilot Mega 2.0, the newest autopilot from 3D Robotics/ DIY Drones is mounted in my trusty Multiplex Fun Cub.
The code is 2.27 uploaded via the latest ArduPilot Mega Planner.
Tested were Manual, Stabilized and RTL (Return To Launch) modes. The Fun Cub's Surface Controls were twitchy because I did not put some expo on the ailerons and elevator.
On RTL mode, the Fun Cub was getting battered and shoved by winds on altitude, hence I cannot say if…Continue
I found this nice blog post, how to run LEDs with the relay switch. I modified the software to work with AC 2.1 firmware. And I added functionality that you can set the limits for the low battery warning with mavlink parameters.…Continue
being a complete novice with autopilots and quadrocopters in general, I just got my stock 3DR kit completed and was able to fly.
Some observations that might help newcomers to get the stuff together:
