I think for the hobbyist, the only real choice is an open source autopilot. Unfortunately with a closed source solution, you are stuck with the feature set that the developer wants you to have. Another major advantage of open source autopilots is that reading the source code is a valuable learning, and troubleshooting tool. Even if you never intend to modify the code, just being able to look at it can be enough to resolve a problem.

Decided to put VicaCopter 2.0 on vicacopter.com. This is the last version for single rotor copters. It's mainly a reference, since no-one will probably ever replicate it.
This version uses ground based autopilot & has the most detailed schematics of them all. Embedded computers were never cheap & never provided enough computing power. The high cost of sub micro servos, rapid servo wear, difficult payload mounting, & tail rotor effects were counting down the T-Rex clock. A… Continue
I made this non exhaustive list of skills which are nice to have if you want to build your own UAV.
I think a basic handle on all of these skills will greatly help anyone who wants to build a UAV. If you want to build a UAV, and lack a lot of these skills, don't take this to mean you cannot do it, just understand the magnitude of the difficulty, and be prepared to press on in the face of adversity and to teach yourself a lot. When I decided to build a UAV, I had never even flown an… Continue
Yet another IMU using Paralax's powerful 8-core Propeller chip. This one on a home-built quadrotor. Flying in IMU-assisted manual mode now, although I assume autonomous is just a matter of evolving the…
A quick note to introduce myself, I have been RC flying since I was a kid, recently I made the jump into electrics after years of tinkering with IC engines. I like designing and flying (sometimes!) my own SPAD planes also. I have been playing around with Spad FPV and camera platforms. Mainly building the plane around the camera.
I am trying to understand the technical and electronic aspects of DIY Uav’s. I found this site very useful in getting to grips in… Continue

BlimpDuino is in the hands of beta testers, so we're doing some last minute tweaks. The current code works on boards version 431 and up (don't ask about the numbering schemes--they're based on internal versions. When… Continue
Yes..thats right. I have eventually developed all the above said techies in a past few months...A very thanks to DIY for the help i've found in posts and digging stuff sround on the site.
So, inow finally have a EM-406 based Autopilot.
Gps runs in NMEA but now i've hooked up to Binary(WOW i dint beliv its gonna be that straight....beliv me guys binary is far simpler as much we thot its difficult).
It sends data to Autopilot (self made) which uses AVR atmega16
I used… Continue
Im trying to read the information from a XRX trough the rs 232 connector. Does anybody know how is that information arranged, or baud rate used. I just couldnt figure out the signal that the XRX is transmitting.
Jordi's done some heroic work squeezing the maximum out of the Arduino platform (with some help from Arduino co-founder Massimo Banzi. We finally have a code base that does everything it's supposed to.… Continue
okay, i suddenly had a burst of energy towards this project, and then SUDDENLY, i disappear for a few weeks. What the hell right?
For those of you who haven't been paying attention to Hard forums deals, or wanted ot build a new computer, two things arose that grabbed my attention, and my bank account. For those of you building a computer, listen up, because the price keeps going up...
MS cashback is giving 30% off of any BIN ebay items. this is great.
If you've been wanting to move to a >1Hz GPS receiver but were holding out until a retail version of the awesome U-blox chipset was available, today's your lucky day. Sparkfun has just started selling the… Continue
This is a quick video of Blimpduino, just void my voice comments =P, the motors are little bit unbalanced, the left one is pushing harder, nothing that can't be solved by software =).
Is holding altitude with PID...
Jordi's been hard at work on the BlimpDuino code. Here's the latest version, which he describes as follows:
"Wow, a lot to explain! I added a lot of interesting functions, it will blow your mind ;-)
First I added a smart delay system. If you need to delay() something you can use the smart_delay(1000) function, and it will delay the value between the () and spend the time capturing IR packets rather than… Continue
this isn't a UAV post. I just wanted to point you at an inspirational RC aircraft site from a guy near me. His write ups are amazing, the level of detail and lists of all hardware is brilliant.
Check out Don's experimental projects once you've seen his aircraft videos.
For those of you interested in learning about embedded computing with a modern, open source platform, the new Arduino Starter Kit from O'Reilly looks great. $89 buys a lot of useful stuff.
OReilly's also releasing a… Continue
Everyone knows Air Busses have problems, from the 2001 crash due to rudder failure to the 1988 takeoff crash on GooTube, so no surprise that the latest sudden 650ft descent of an aircraft was an Air Bus whose IMU malfunctioned & sent out an erratic orientation.
What a thrill that our home made IMU & autopilot can be at least as reliable as the world's largest, low bidding, government subsidized passenger airline manufacturer's. Our IMU has drifted from vibration but never… Continue
