I havent read the whole thread as i am in a hurry.. but i would suggest the following approach-

-use gears to increase speed. theory
-change the motor for a higher rpm one, also see if there is any room to increase the voltage/current to the current motor.

you can replace the motor and trigger ckt with a higher power/rpm motor and a SCR if the present trigger does not support higher current/voltage ratings

Signal from TX-2B/ to RX-2B

Hello,

I want to make a remote control for a car using an AtMega16 and for this i want to replicate the signal emitted by an TX-2B. I have read the datasheet for TX-2B IC but i'm not quite sure if i understand the encoding rules...
If anyone has any certain knowledge about this .. please help.

What I understood is:
- i have 2 units for my signal W2 and W1;
- a normal word is composed of : 4*W2 + n*W1 , n depends on the direction of the car;
- an ending word (and this i'm not sure) is 4*W2 + 4*W1;
The mechanism how I got it is .. while I have input I'm sending concatenated normal words, when the input stops i send one ending word.

Please correct me if i'm wrong.

Thanks.
