Make a Micro FM Transmitter
Learn to build a simple FM transmitter that can be used to eavesdrop on your workmates or friends.

I would like to know how to make a standard bulldog car alarm key fob transmitter stay on permanantly sending out the panic signal while having an on/off switch to control it. Weve tried for days to get it to work but cannot get it to do more than a pulse mode, ie: Switch it on it sends out a burst signal and then shuts off. Any suggestions?

@michael, have you tried relays? why not adapt kipkay’s keyboard hack circuit replacing the card circuit with the FOB? i am sure there is a way around that using transistors and relays…
