Make a search for Barebone Arduino OR breadboard Arduino and you will find a lot....

NikTheGreek

So for gps support you need an additional arduino to the main flight control arduino...And the main flight control must be one of the mega boards right? And the secondary can be a pro mini or nano?..The main arduino can't be a 328p board right... Hope I understand correctly now. Yes No Yes No Main ...

Btw which i2c gps is good for the job & where did you guys buy it? I'm not sure if i understand correctly your question They are using the 2nd arduino to "convert" any GPS to I2C gps this way.... RX & TX from GPS connected to RX&TX of the arduino . PIN No2 is RX and No3 is TX ...

NikTheGreek

Question.

In I2C_GPS the gps connected to D2 & D3 ?

Hello again. I'm very interested about GPS guidance impementation . I've bought some time ago an Skylab SKM53 and i would like to try to help you , at least as a tester , in this project But seems that i m a bit " lost " and thats why i ll try to resume what i ve understand. So... 1) We ar...

NikTheGreek

Just.....WoW !!!!

NikTheGreek

It's me again...

This time i got a video of the " tilt motors system ".
Seems that is working fine and It's quite stable .
The distance from motor to motor it's about 85 cm and the "free" space to build the wings it's 35 cm for each wing.

Less moving things, less things to break! TRUE..... Nik, I think it would be better to use two bearing holder arms verse one as illustrated in the attacked picture. The actuator horn is fine. Yep..you are right...two bearings means more stable I must order some from ebay because i got only six of t...

CG ?? = Central of Gravity ?

NikTheGreek

Thank you guys for your replies.

Here is a first draft of my idea.
I hope you understand what i want to do.

Later i will post and a real picture of what i've done so far.
Thank you again for your time.

NikTheGreek

Good morning. My "DREAM" is to build a Bicopter that will be able take off vertically and later to be transformed and fly as a normal airplane. I know is a "long shot" for me ...but as i said it's my "dream". So i got some questions for all you , i case you want to help...

NikTheGreek

Take a look here

NikTheGreek

I think that is time to buy my first magnetometer sensor.
And of course i need to be cheap and reliable

Any suggestions ?

NikTheGreek

I know that probably i ' m the last one that i sould speak about this since i'm totaly new and unexperienced . On the other hand i think it wont harm iff i say my opinion. So far you have done exelent job with the Multiwii code. Seems that working perfectly without significant problems(pls correct m...

NikTheGreek

I connected both directly to my Receiver
Both consume the same amount of current.

Seems that at least i can use it with no problem....i hope

NikTheGreek

I would check the current consumption of the two ESC´s with motors stopped and without load on the BEC to check if just the BEC voltage is faulty or if the fault creates a short/high current consumption also. Thank for your answer...i will do that for sure I have always used a separate ubec to powe...

NikTheGreek

Hi again. The last two days i'm facing a "strange " problem. i m using one of the two ESCs to power up my circuits(Arduino - WMP - Nunchuck - 2 Servos - Receiver) At the begining everything is working good but a few seconds later all "system" freezes and is not responding to my c...

NikTheGreek

I'v switched the servos and seems that everything is working fine.
Do you think that will affect somehow ?

NikTheGreek

Maybe if i switch the servos ?
Left to right and right to left ???
This will affect the Bicopter ?

NikTheGreek

I make my Bicopter and i realised that when i push the pitch stick front both motors are tilting back !!! Both servos are connected correctly according the "manual". Left servo to D11 and right Servo to D3.. There is an easy way to reverse the way my servos moves? I saw in the config.h tha...

NikTheGreek

ok ok..
you convinced me..

i'll do it but later.
for now i have bigger things to solve

NikTheGreek

Thank you patrik ..but all this sounds like Greek to me .

Maybe in a future life i ll be able to understand .

Thank you anyway

NikTheGreek

Thnx PatrikE....but..what kind of file is this ??
I cant read it

NikTheGreek

Hi.
I got a Turnigy 9X transmitter and i'm trying to setup all the switches that my Bicopter need to fly.
I've searched a lot in the web with no luck.

Can someone please help me ?
Thank you in advance.

You can ARM with both Yaw or Roll.
But only if you have throttle at min.

If you use a AUX channel to ARM, The stick start will be disabled.

Thank you ONCE AGAIN !!!

NikTheGreek

I've set up again the ESCs as you suggest. Fist i've turn all to Default and throttlerange as you said in your previous post. AND..... Success !!!! Both motors run smoothly and balanced !!! Thank you for your valuable help. BUT..... (There is always a but..) i noticed that motors arm also when Throt...

And here is a video

Hmm.. i ve used this to calibrate my ESCs m And what i ve set is... 1.Brake set to off 2.Battery set to NI-xx 3.Cutoff mode set to Reduce Power 4..till end i didnt change this settings Now.. in the config.h i've set as minithrottle 1220 and in the GUI Throttle min 978 - max 1915 When arming the moto...

NikTheGreek

I've already set the minithrotle in config.h to 1300 but seems that the motors spinning too fast..
so i'm decreasing this value to 1220.
At this point both motors are spinning but the one much faster than the other.
I guess that both must run at almost the same speed . Right ?

Oups.. i forgot to thank you Th0rsen !!!

IT'S official.....D4 is DEAD !!!!

Never mind ... i will use a spare one i got in my drawer...
Let's hope that i won't burn this ...

NikTheGreek

If yes, check again the cables to D4.

I've done this.... 2 and 3 and 4 times....

do you think that there is any chance the D4 burned ?

All other pins working as expected.

NikTheGreek

Hi
i was trying to calibrate my ESCs to arm properly and i lost ROLL !!!

In my receiver's output (CH1) working fine..but when i connect it to my Arduino i don't get any readings in the GUI..
I ve also double check the cable from receiver to Arduino (D4).
Any suggestion ??

NikTheGreek

Happy New Year to all...

I have build two "packs" of Wii MP and Nunchuck using 4 different boards (2WiiMP and 2 Nunchucks)
The 1st pair is more "sensitive" and the 2nd seems to be more..."stable"..
wich version one sould i use for my BiCopter ??

NikTheGreek

kalle123 wrote:I don't get it. Is it an arduino only or a complete multiwii ?
For arduino only I am using those

Its exactly the same..
the only difference is that i have add 3 rows of pins in each side of the chip .
This way i think is much easier to connect the servos - sensors - or whatever you like to.

NikTheGreek

Goodmorning.
I just wonder if this ... http://www.grobot.gr/phpBB3/viewtopic.p ... &sk=t&sd=a
can do the job ?
Its light and simple .
Please forgive me cause its writen in Greeks..but i think you will understand what it is.
