The Chaoskopter - Stage 1
The build before the Chaos Camp 2007
The finished Kopter after the Chaos Camp 2007:
The Chaoskopter - Stage 2
After my first frame was broken i build a new one with a motor axis distance of 46cm. For the cap i used a salad bowl as prototype and make a copy with epoxy and glas fiber.
It's not looking good, but i can see it very good when i fly.
DigiCam-Mod
Dates from the Camera:
- 7,2 Megapixel
- 800x578 Pixel video resolution (!!!)
- TV-Out
Buyed and demounted.
Functions with the RC transmitter:
- remote trigger
- Zoom is prepared
- video transmission for controlling
The camera is mounted under my Kopter. For the remote trigger i used a BL-Ctrl. I modified the flight control source code too.
MKLight
The light at my MK is build with a unused BL-Ctrl and 30 LED's. 10 LED's and the resistors are soldered at one stripe of a hole board. Against to the first intention to switch every LED alone, i switch now 10 LED's at one. Because the BL-Ctrl has three Mosfet groups i can only switch three LED-stripes. Continouse lightning is boring, so i implemented some effects. The light can be switched on via the remote control. Therefor i modified the source code of the FC. The FC generated a rising edge which is detected by the BL-Ctrl and used für switching the light effects.
Build: The positive LED contact has to be solder at the top of the BL-Ctrl, the negative contact has to solder at one of the minus pads.For the Switching with the RC/FC i use the INT0 interrupt. Therefor i solder a wire at the ISP-Pin 6 pad. This wire has a connection with the FC - J9. The power source is the LiPo.
Source Code BL-Ctrl: mklight.zip
The FC source code modifications::
main.c:
int main (void)
{
...
PORTD = 0xF7; // LED
//Hoppel Mod
DDRC |= (1<<PC6); //J9 as output
...main.h
... #define CFG_LOOP_LINKS 0x04 #define CFG_LOOP_RECHTS 0x08 //Hoppel Mod #define J9_HI PORTC |= (1<<PC6) #define J9_LO PORTC &= ~(1<<PC6) ...
fc.c
... GyroFaktor = ((float)Parameter_Gyro_P + 10.0) / (256.0/STICK_GAIN); IntegralFaktor = ((float) Parameter_Gyro_I) / (44000 / STICK_GAIN); //Hoppel Mod if(Parameter_UserParam7 > 75) J9_HI; else J9_LO; ...
In the MK-Tool the Userparameter is assigned one of the Poti's.
