There is still a lot of choice over hardware to make
I think that using all the hardware of a Turnigy 9X transmitter would be a good start point.
Maybe adding 2 ps3 gimball to the set.
I know we can burn the bootloader of Arduino into the Turnigy 9X transmitter making it Arduino compatible.
Maybe it coud be a good idea to use this processor… but would need many change to the code which i can’t do myself.
(but if someone feel like doing that way and help…???)
Great idea! I’m definitely in the list for one, as long as it is less than $200 (student budget you know!)
I’m not the most knowledgeable person about CAD for the design or electronics but will pitch in if it’s in layman’s terms! Good luck!
ii) Or potentially an ARM cortex M3 variant, in Arduino Due format and programmable in a similar environment. It has 72MHz processor, 39 I/O, 3 UART and only weighs 17g. I think it is half the size of an Arduino Duemilanove. Costs $44.99 seeedstudio.com/depot/leaf-maple-cortex-m3-p-670.html?cPath=132_137
There are some other $15-$20 boards I can’t remember their names but I think they were Arduino compatible.
You could always design your own, but that could be lots of effort and testing and what not.
Or, I guess what most people including myself struggle with is the DIY case. Since you have a nice CNC, you could manufacture different versions of the cases (with OLED, without OLED etc) and leave the electronics for the hobbyists. Sell the whole thing, either in a 'kit of sorts, including Gimbals, Switches etc without any electronics or just the base kit without anything. Then, Arduino lovers can use Arduino boards and Kurte’s code, or Propeller heads can use Quantum’s Open Source code (pictures above) and basically tailor make the transmitter to suit their own needs. It will mean you have a lot less work and everyone is happy as well. Hopefully.
I already have like 10 ProMini board and a Arduino Mega
I would like to keep the thing small.
ProMini only have one uart … :
All depend on how many. I/O I can make a shield board but only if everything is lock down.
Hey Dial, have you ever thought about using carbon fiber arrows from a hunting store as your arms on your quad copters? You could have holes cut just slightly smaller then the size of the arrow out of the PCB material you use right?
They are pretty cheep, although I know PCB’s are also cheep!
Actually you should have your friend cut quad copters out of un populated spare PCB’s they might look pretty cool looking!
The board is made for Multiwii code but it’s basicly a Arduino compatible board with pins already made (-+S)
It does include USB Ftdi and Gyro Acc Baro sensors (which we could use if we need to)

Supported MegaPirateNG and MultiWii firmware
Up to 8-axis motor output
8 input channels for standard receiver
4 serial ports for debug/Bluetooth Module/OSD/GPS/telemetry
2 servos output for PITCH and ROLL gimbal system
A servos output to trigger a camera button
6 Analog output for extend device
A I2C port for extend sensor or device
Separate 3.3V and 5V LDO voltage regulator
ATMega 2560 Microcontroller
MPU6050 6 axis gyro/accel with Motion Processing Unit
HMC5883L 3-axis digital magnetometer
MS5611-01BA01 highprecision altimeter
FT232RQ USB-UART chip and Micro USB receptacle
•On board logic level converter
•Match the standard of RoHS

Input power selection
One of the following way
Connect 5V power cable from ESC or UBEC to the ESC/Servo port, the J1 jumper must be closed.
Connect 5V~12V power cable to the extend power port, the J1 jumper must be removed.
When using Extend Board, AIO PRO must be powered from the extend power port.
I have two MultiWII boards, a SE and a normal one…they are cheap and the code they have on them isn’t really that difficult to modify… they work pretty good.
I’m still in the process of getting it flying… bit of a headache actually… However it shouldn’t be, i see these POS duct tape jimmy rigged crap rigs flying and its ANNOYING!.. It has to do with adjusting the trims which I don’t quite have corrected yet.
The idea would be to make the center frame and each of the motor supports out of your G10 material then the booms out of premade bow and arrow cut at specific lengths.
If you have look at the link i have post you would see that i have my Own multiwii Shield and MiniController.
So yes i use Multiwii all the time.
If you have questions about Quadcopter or Multiwii just send me an email: [email protected]
This thread is not about Multiwii but about Transmitter, i am looking at Multiwii shield that have a Mega processor cause they have mutli UART port on them.
And all Pins are already populated with 3 pins (Ground - Positive - Signal)
See I have two ER9x transmitters and the telemetry module for them as well as the PPM reciever “D8RSP” which does PPM out as well as 7 normal channels. The PPM out actually outputs all 8 channels.
It also has two way serial communication… which means you could probably take advantage of a uart for … something… NMEA GPS broadcasting? back to the transmitter perhaps…
Actually scratch that, you could probably just have the control board broadcast back the actual lat and lon / dist to home… and whatever else.
I’ll jot down that email address, I might have to make a video or something of what my quad does for your feedback… Honestly I know its something minuscule.
That control is neat, however I think I like real gymbals better to be honest.
Not sure if this will have anything to do with using my code as it sounds like you may still be interested in RC and using different processors and different controls … But it sounds like you are having fun… If you wish for Atmega and 3 pin headers, you can also look at the Axon controllers: societyofrobots.com/axon_select.shtml
I have an Axon2 that I was using on a Brat, before the brat got recycled into parts for the 2nd test hex robot.
(student budget you know!)
