What is the right RF channel?!

I saw in the nRF24L01 Datasheet Page 23 that the nRF24L01 can operate on frequencies from 2.400GHz to 2.525GHz (125 channels). The RF channel frequency is set by the RF_CH register according to the following formula: F0= 2400 + RF_CH [MHz] e.g. channel 107 at 2.507GHz. WLAN (IEEE 802.11b/g/n-2.4) us...

The values should be the same after repeating the test if they are not +-1% the same you should re-calibrate it. BTW: To get 100% is inpossible except you calibrate with propellers on the...

I guess the PWM signal of the motors could be used to make a sound if the PWM frequency matches the resonance frequency of the motors.

Re: Balancing during the assembly

At the moment, the best and fastest way is to have some spare propeller, exchange and test it until you find the best setup. For people with more patience :D you can balance the propeller it self. I prefer to find the heavy side of the propeller with the needle and magnet method and then use sandpap...

Re: Ubuntu + PS3 Controller problems

I know you are using your controller via USB, but if you push the PS button the controller sends a signal over BT on your PlayStation to turn it on. The only way to stop this is to unplug your PS or you pair the controller to something else.
