Servo precision - finding low current draw, low/any speed, <<<minimal loose-very precise>>> standard or mini servo.

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…

WFOV 6-DOF Vision System for Optical Flow Odometry using ArduEye and Arduino


As a participant in the Harvard University Robobees Project, our primary task at Centeye is to develop a vision sensor system that will fit into a small flying robot about 2cm in size. The target weight budget for the vision system is 25 milligrams. While we still have a ways to go before achieving this, we…

I've ported MinimOSD to Remzibi's hardware

Hello everyone. Recently I port the MinimOSD to the Remzibi OSD's harware, so a poor man can enjoy MinimOSD's convenience now (no need to modify APM's software anymore).

Because of the limited flash space of Atmega16, the code of OSD is slightly changed, and it is not compatible with Michael's original config tool.…

Trying to build a DIY autonomous sailing boat.

Recently I have joined this community. However, I am not working on building a UAV but a DIY autonomous sailing boat. It might not fly but such a boat can use the technology developed for UAVs.

With a lot of help from a good friend I have been able to design a small sailing boot made from PVC, which has no electronics in it, yet. It only sails in one…

GoPro fun in the park, quadcopter with ACv2.5

Had a little fun flying in a local park here in Johannesburg, South Africa. Used a GoPro Hero on my own design anti-vibration mount and my quad running the newly released v2.5 firmware. Click on the photo to go to the youtube video.

Quad specs:


KDA20-22L motors from Hobbyking, 11x4.7 APC SF props

2 x Super Simple 25-30A ESC's from Hobbyking, two more on…

Australia leads the way again

If you are planning a commercial UAS operation down under new proposed guidelines are on the table for simple RPAS flight.

Away from built up areas, within VLOS below 400' and outside of CAS. Much the sort of thing that might come into place in the USA eventually. 

Its the first qualification in the civil sector that I know of that is so well defined. Fifteen units to pass.…

MinimOSD Setup Video

Hi Everyone. Above is an intro video to the minimosd. It still needs a tiny bit of tailoring but I figured I would send it out to the community for review. A video series like this could be beneficial for our community to grow in the future. Open to adding on a distributor logo for some help supporting my own hobby/builds.

Of course the video…

Er9x transmitter now with MavLink

The er9x transmitter now will display MavLink data on the LCD.

Gerard Valade a DIYdrones member wrote the software and myself who was the principal debugger.

Works at 19200 and 38400 baud. Still have a problem with 57600 baud. Some kind of timing issue yet.

Here is a pic of the arduplane 2.30 MavLink display on the er9x.

There is an Xbee inside the er9x to…

Yet another Frsky Android project (IOIO inside ;) )

ArduCopter 3DR Flight 2 a success!

Man I love this thing!  Super rock steady and fun to fly.  I moved the GoPro to an underside mount facing forward so not to get the props in the shot.

Power Distribution Board

The soldering of PDB was not very difficult thanks to the detailed manual. However, I feel that soldering the Female Dean’s Receptacle first might be convenient as the narrow gauge wires won't came in the path of soldering gun. Though this is not a big issue.…

Building the Raptor


This week I got a great start on building the Raptor - a 48 inch wingspan flying wing. I learned an enormous amount of information:


1.) 3M 90 Spray foam Melts XPS Foam...

2.) Loctite Foam Board Adhesive Is a great foam, give it plenty of time (24 hours+) to dry/cure

3.) When cutting out flying wings with a hot wire cutter, both sides of the wing (if using a two template method) need to communicate very well

4.) A 12v car…

For the GeekDads among us, a new community site

Some of you may know the history of this site, which began with a project I did back in 2007 with my kids to try to get a Lego Mindstorms robotics kit to fly a plane (it worked). That was part of a series of science/tech projects…
