RF amplification to power IR LED

AI Thread Summary
The discussion focuses on amplifying radio waves from a receiver to power an IR LED for an air conditioning remote. The user is considering charging a capacitor to provide sufficient power while maintaining the integrity of binary transmission for IR communication. Participants are asking for details about the source and power of the radio signal, the distance of transmission, and the type of receiver used. These specifics are essential for providing a suitable solution to the user's problem. Overall, the conversation seeks to explore practical methods for achieving effective RF amplification for IR LED applications.

Hello, I am new here so my apologies if I have posted in the wrong place.

I am trying to amplify the radio waved I get from a receiver to power led that will ultimately be used as a remote for the AC.
I have contemplated "charging" a capacitor until it has enough power to power the led however because of the way IR remote communication works, I need to keep the binary transmission.
Any help would be greatly appreciated.
cheers

Hi snoopy
welcome to PF

where is the radio signal coming from and what power is that transmitter
Over what distance is the radio signal being transmitted ? what is the receiver ?

answer those questions and maybe we can help with a solution :smile:

cheers

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Beam on an inclined plane'

Thread 'Beam on an inclined plane'

Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
