OSD, object tracking and (possibly) optic flow on the cheap?

Ran across this today:

It's a dedicated video (PAL or NTSC) Arduino shield with passthrough capabilities. Nothing fancy, just a sync separator and some passive electronics. Obviously, it needs to be mated with an Arduino (additional one, alongside APM, of course), but it's plug and play and comes with a neatly put together library. Question is, can this + Arduino physically fit an… Continue

More AMA "disinformation"

"an agreement on the proposed language was a little more difficult to achieve in the House than in the Senate, and we were unable to settle on the exact verbiage before the Bill was sent to the floor for…

Build new Quad + frame

After the crash on yesterday I again rebuild the frame using new 12mm aluminium square pipe with same length of 14inch or 355mm with 10x4.7 props. Built the frame and mounted the motors and electronics. Reloaded the software with 4.5 + reboard firmware.


During the test it seems to be good. Trying to achieve a hover vehicle by adjusting the EPA and trims. Most of the the part did work well. But as soon as I finished testing I switched off the Tx thinking that I unarmed the…

Well, to work in a spin stabilized mode, Marcy 2 would have to spin a

lot faster than a 3 channel coaxial copter can.  Without spin

stabilization, a $40 Syma S107 or a $25 Sky Invader didn't matter

because either way, we needed another gyro to know heading.  A 150

second flight time doesn't demand a very accurate gyro.

Mass produced Marcy 2's would use…

Yet Another Build Log (YABL) - Part 2 - Motor mount LEDs

Since the current ArduPirates code (as you all probably know) supports LEDs not only as a navigation aid, but as a status indicator as well, and since i had nothing better to do while i was waiting for a replacement ESC (one of the four i got turned out to be faulty) i've decided to install them in the jDrones' motor mounts.

Now, i could've just pulled two wires from each motor mount, crimp some female connectors to them and plug them in the OUT4-OUT7 ports, but… Continue

Wireless RF Transceiver 431-470MHz - Good Enough for Learning?

Other than "you get what you paid for" Anyone have a reason Not to buy this pair? 

My personal goal would be to use it as a learning tool, prepairing for adding telemetry to my projects. But it should be usefull too.  Secondary use in some project around the house, ie halloween automation, laser guided water splasher (anti-cat crap in the yard device currently in planning…

Repairing an AeroQuad Motor Mount

I attended the Bay Area meetup last weekend.  One interesting thing that Chris Anderson mentioned was his philosophy that it's often more important to make things that are easy to repair than it is to make things that can't break.


I almost immediately had an object lesson in this by crashing my quad.  Two props were broken, so I put it in the car to take care of later. When I got it home, I noticed that one of  the motor mounts was bent to an almost 45 degree angle.  Fixing…
