Walkera Magic Cube Computer Control

The Next Sensor was Invented by Vikings

There have been discussions before calling for reliable and accurate alternatives to GPS. The Vikings may have had the answer without knowing the physics. They were adept navigators at latitudes where frequent cloudiness and low sun angle(winter) could have made direct observation of the sun difficult. Legend has it that they had a magic stone, called a…

Sonar behavior

I have been reading with interest the sonar usage (right sensor, etc.) because I had already purchased the previously recommended sensor (EZ0) but had yet to add it to my quad. After reading the posts by Maxbotix and others, I went ahead and took the plunge. I added a 100uF capacitor directly to the board…

3dr Telemetry Radio No Longer Naked!

When I received my telemetry radios and got them working with a minimum of fuss, I was thrilled. I quickly decided I didn't like the idea of having a bare board hanging off my Motorola Xoom tablet, though.

After a little research I located and obtained a USB dongle case that looked like it would fit. A little thought, a couple holes, and a slight mod later I had a finished unit that looks factory made. Presented in pictorial form below are my results,…

GoPro Wire Rope Mount with Furniture Coasters

 

 

 I built this Wire Rope GoPro mount out of a couple of Furniture leg coasters, a Bicycle Brake cable and some electrical brass wire connectors removed from their plastic housing. Test flown this morning and here is the result.

I'm very pleased with the video as I have tried many ways to remove the rolling shutter effect previously and this is by far…

You won't need a whole lot a space to launch and land.

After many flights with my DIY frame consisting of 3DR Electronics stack and Landings legs, all the other parts are homemade form aluminium, i thought it's about time to launch from my balcony and take a spin down to the lake...

 

How easy was that...

Eva: A new open source autopilot!

               

                Arduino is awesome, and the autopilots based on them are great. Not only do they support an incredible number of external devices, but also don’t scare away the novice developers. Easy programming and versatility are nice but the cost at which they come at is somewhat of a letdown.…
