Android Studio - Waiting for device @ Ubuntu 

I have started to develop to Android on Ubuntu.
At my first attempt when I have tried run my app on the device, the device shown up as ?????????? in the Android Studio Choose Device dialog.

The problem root cause is the access rights around the device descriptors.

The ADB daemon is started with the user's permissions, so I had created an udev rule to get access to the device:

mm@lapos:/opt/android-studio/bin$ cat /etc/udev/rules.d/51-android.rules
# Concorde tablet (18d1:0003)
ATTR{idVendor}=="18d1",ATTR{idProduct}=="0003" MODE="0666"

Tyco Terrain Twister reverse engineering 

I have a Tyco Terrain Twister without transmitter.
The demodulated signal encoder in it is on a small board on board PCB.
Unfortunatelly there are not any useful information about it on the web (how the encoding is works etc.).

I am planning that I will replace it with small AVR/PIC based custom circuit whihc capable to encode PPM signals

The RF receiever is also in a separate circuit it was manufactured by the Jetta Company Limited.

I have desoldered the encoder circuit and reverse engineered its pin's function:



My pin counting starts at the top left corner and continues tor right.

See the pins function below:
