u asked

u can build a very simple remote using 2 555 IC's (moudulator and freq generator at 38 Khz )
At the other end u can use a TSOP 1738 ( Ir Demodulator ) and 4017 for flip flop should provide good range and detection :?

An Ir transmitter is not all that hard to build. Just connect a infa-red led to a battery with a resistor arranged in series so as not to destroy the led and a switch. Then, connect a infa-red reciever to a battery and resistor in series with any output you like (motor, led,solenoid).When the switch is pressed the output should come on.
