Hi all,

Apologies for the video in portrait, hope it is still visible.

True to the DIY element of this community, I've devised a small, cheap and simple way to attach items of any kind to my Quadcopter and via a servo to release it.



It's quite simple yet effective, using one servo and some pieces of metal and a screw to mount it…

Here's a simple servo-controlled very light GoPro mount for any UAV. I have machine tools to make this, but you might be able to do it with simple home tools. The real trick is a direct connection between the servo and the camera rotator, and to use a control link ball (left side in photo) so you don't need to hit…

Hi!

There are a lot of new properties. You can search servos: by type (digital/analog), or you can choose torque and speed (4.8V, 6V, etc), or gears (metal, plastic):

Right now my database (rcdetails.info) contains:

>800 brushless motors,

>300 gas and glow…

hey guys,

 just thought I would show of one of my latest efforts.A servo hacked continuous, controlled by a maple reading a 12 bit absolute encoder controlled to move to any absolute position.…

After reading several blog posts and discussions about folk having startup issues with ESCs, APM2s, etc, I thought it prudent to build a simple servo tester to allow ESC checks sans APM functionality. The new issue of Make Magazine, #31 (I did a discussion post last week after the mailman delivered it) has a…

Hi all,

I am unable to find exact information about servo tolerance.

For example very popular Futaba 3001 tend to have a lot of loose because ot the gear precision, yet when they run all is ok (besides that they are slow).

On the other hand Hitec HS-425 appears to me to have null loose.

Hitec HS-225 have little loose and is very fast servo, but in order to hold its position requires huge power.

Most digital servos tend to be either slow and fast, but have…

I tested the auto landing feature on the APM I've installed on my Nova. Unfortunately, something has gone awry with the APM (the ADC may have failed) and the APM couldn't load the accelerometers or gyroscopes, causing a stabilization and auto flight mode failure.

 

I'll be repairing that as soon as possible, and work on getting the Nova back in the air. Meanwhile, I'll do some FPV flights to see if I can't start getting the hang of…

I was looking for a parachute ejection system for one of my small UAV and I found the miga motors nanomuscle. Cheap  SMA system linear actuator (less than 10$ unit), I was thinking about using some instead of the servos on UAV.

Hello everybody, just wanted you to know that I just published a paper here https://sites.google.com/site/imager3d/quadrotor It is a brief description of a concept-proof steering system for Quadcopters, based on the transposition of the center of…

Speaking of servos (the topic of my prior post), the GS-1 gyro server self-stabilizes (in one axis only)...

I'm curious... has anyone used a pair of these to construct a self-stabilizing pan/tilt gimbal for their aerial shots (plane or copter)? It would certainly make for less parts and wiring, being that servos will still be required to do the job (so why not cram the gyro in the servo… Continue

In various groups and blogs I peruse on here, there's been talk about I2C control of servos (as opposed to standard PWM). This certainly solves several problems, as it allows one I/O port (I2C) to service over a hundred servos with ease. With some built-in intelligence, the servo itself can… Continue

Hello to all community members.



I have just received to my e-mail this new and very improved servo controller:

You can find product details at: http://www.01mech.com/supermodified

I copy the following from the site: …

Original ArduPilot controls 2 servos (throttle/yaw) by autopilot code or from RC receiver. Other 2 servos are controlled by FMA copilot (or again manually by RC). Although there're servo IN3/4 and servo OUT 3/4 connectors on ArduPilot board, they're at present unused (actually only pass-through control from IN3/4 to OUT3/4 is connected).



Yet there's simple way to control all 4 servos from ArduPilot code, and use other two servos for interesting tasks, such as moving plane's camera… Continue

If you don't like too short connection cable of GPS to ArduPilot, then here's a fix. Longer cable and better connector will solve 2 problems:

- more flexible assembly into a plane

- easier program upload to board (since GPS cable must be disconnected before uploading)



Original connection:…

I found this camera mount, it could make life easy!

the atmega168 on the arduino has a timer1 which has input capture capability (see this application note and datasheet for atmega168 for details). using it, it's possible to do the pulse timing in completly in hardware (no errors, no jitter), and having a interupt readout the measured time.



here's the code:

Hi all,



this post is an "how to" for an Arduino pan and tilt camera moved by a Nintendo Wii Nunchuck.



Here's the video so you can check how it'll be the result. The most important thing is the precision and responsiveness of the system.





Here it is for all that asked me in the past and for those interested in putting something similar in their UAVs.



It's an "old" project I've posted the following video… Continue
