Hello all,
I would like to make a very simple and preferably small transmitter on perfboard/prototype board (I do not have the materials to make PCB's).
Now while most of the circuits I find online are for FM transmitters, I am open to any other methods of tracking that you guys might have. For the FM transmitters, I found this to be the coolest/easiest one since it does not require a pcb: **broken link removed** . However, the LM3909 is discontinued. Can a 555 IC perform the same operation as that LM3909?
Any ideas will be helpful, but remember, I want simple, non-pcb, and somewhat small. Thank you.
Edit: Also, if there is a way to minimize the error in making a hand made inductor out of wire that would be great. By this I mean, I would prefer to have a variable inductor that I can just put a screwdriver to (like a potentiometer) and modify it's value to get the desired frequency
