That s a fun little device to own.
Can you tell us a little more about though?
Like - how did you come up with this idea?
Its KEWL - reminds me of the older "plug tester" neon bulb - used to find Hot from Neutral.
Yep, I made one for myself about 1 1/2 years ago. Except I did not put the components inside of anything. I just use it as it is .....
Works damn good for following the RF path and troubleshooting .....
great idea Crossbow!
i haven't looked at the circuit, but is there enough RF coming in to a radio's antenna socket (no signal) to turn the LED on?
LC
How many volts Led was used for the rf probe?
