GUI almost done...

The GUI for my tricopter is almost finished. Watch a screen capture video here. It's working very fine and it is pretty handy.

 What needs to be added is a possibility to flash new firmware to the tricopter. I would like to include avrdude in my GUI, but I still need to do some test with avrdude, Arduino bootloaders & RS232 cables... The GUI will be released when it is finished.
The Arduino pro mini m168 is now filled to 85%. I will change over to an Arduino pro mini m328 so that I'll never run out of space.
It seems as if I am going to build an extra tricopter with the ESC's from mikrokopter.de. That is a good opportunity to test everything again, making sure that building a Shrediquette DLX doesn't cause any problems.

Edit: Today I sucessfully flashed my m168 and my new m328 via RS232 + bootloader + avrdude! I also managed to run avrdude hidden inside my GUI (so you don't have to enter any parameters, everything is done automatically with one single button press!). I will soon write an extensive tutorial on how to build a Shrediquette and how to set all parameters etc....

Last project tweaks

I realized that programming an Arduino with Bascom & ISP-Programmer might be too complicated for people that to not work with robots and microcontrollers frequently. That is why there will be some changes to the setup soon:
I will write a tutorial on how to transfer my program to the Arduino via avrdude and a simple RS232 serial link (first, I have to find out if it really works...).
The second simplification will be a GUI, where you can set, change and check every parameter of the tricopter. Development of the GUI might maximally take a month or so. I will begin to make it soon. In the end, making your own Shrediquette-tricopter might work like this:

1. Buy an Arduino pro mini + RS232 cable
2. Get or make the TriGUIDE pcb
3. Get the RC components (motors, ESC's, etc)
4. Build a frame
5. Flash the Arduino using my precompiled source code + avrdude 
6. Install my GUI (TriGUI might be the name...)
7. Set the parameters that match your equipment 
8. Fly

Outdoor performance

Today, I recorded some outdoor scenes. Agility was improved, I think I should try a double-flip....

Circuit and PCB layout released!

Today I can release the circuit and the PCB.  My little tricopter project seems to be fully documented now, it was a success and lots of fun. And now for something new.... I want to become snowboard pro ;-D.
I will most likely post a video of the outdoor performance of the tricopter soon.

This is the layout:
(thanks to "AVR-Frickler" for tweaking the layout!)

And here comes the circuit:

You can download the Eagle files here:
TriGUIDE_v3.zip

Source code released!

Almost exactly one year after starting this project, I can finally release the source code of the tricopter. I translated the code to english (mainly variable names etc.) and added a lot of comments and explanations. I hope that you can understand the code, it is actually quite straight forward. Feel free to ask questions and give comments.
Source code:
Tricopter_02_ShrediquetteDLX.txt

PCB layout etc. will follow during the coming days.
