First of, a better landing gear:
Made from a spare PCB board from another project as a base (strong and flexible). To which a set of foam and plastic wheels on flat carbon bracket were mounted.
Attached with duct tape, the landing gear work perfectly. The PCB base bends under load and if there is any excessive force applied it goes to the duct tape which breaks and tears but is easy replaceable.
Only the bent rod holding the wheels to the carbon bracket kept braking from the glue. Quick fix, reinforced with zip-ties instead of just glue for extra strength.
Now the plane is finally ready for the extra weight of the camera mount, without the need to fix the landing gear after every heavy landing.
And second, to take pictures we need to synchronise the cameras! Yes, the board to let the phone control the servos and the cameras (to synchronize GPS data with shots taken) is in the works, but for a quick test lets use what we have:
Just change the firmware from our rc2usb board to output a second long pulse every 5 seconds instead of the PWM for the servo tester.
Now cut up and strip down a couple of cheep mini USB cables to get the connectors, wire up the power lines to the pulse output on the board and run the wires trough the camera stand.
We are now ready to take some high resolution pictures!
