giving an <b>ir<b> transmitter some strength hack a day
The system using an RF remote, but relies on an IR transmitter to communicate between the base station and the cable box. He found the IR module that comes with the device is under-powered and set out to fix the situation.

You can actually make the IR receiver wires as long as you require, however we're going for the built-into-the-D-sub-hood effect and will use a 9-pin extension cable to position the receiver. What you will need. 38KHz IR receiver 4.7μF capacitor. 1N4148 diode This is the schematic, you can read this right? Oh, okay lets show you how to make this. Step 3. 3. The plan is to cram everything into the D-sub case, it'll have to be organised a little like this.

   i am making a motor driven robot and we are using infrared to do it how would it be possible to get it to go distance wise and get it to work

   when i was in a project about robot control using infra red, i can control it up to 5-6 meter range. i only use a simple infra red circuit that little bit modified on the opamp. i use standard opamp 741, infra red and foto infra red/fototransistor and also another passif component support. that’s work on digital respons. so are you wanna to try?
   can you specify more detail about your motor driven robot
