Very nice use of an Arduino. Nanos are great for so many things. Four this morning I was watching my 3d printer finish a print. Being retired is great! I highly recommend it. Thanks, Paul very good video.
My two cents - if a code doesn't work and it should, don't just leave it; there's more learning to be had there than anywhere else :-) Anyway, interesting little project, thanks for uploading!
Nice work. Some of the Amazon links no longer work. Do you have specifics on the uF rating for the cap and the values on those diodes. Parts # would be great. Great video
Very interesting. Thank you for sharing your knowledge. If I want only to know if frequencies are in that range of 902 - 928 MHz would I just replace the rf detector with an antenna limited to the range of interest?
Great job, I understand the "0 dark thirty" thing quite well "Go ARMY". Keep up the great Arduino / TFT videos. From what I see you wont have any troubles with the ARRL test. The only thing I question is why it took you so long too started. Chat Later Alan Back, N8TIB
+Alan Back Thank you. I passed tech and general no problem. The reason it took me so long....I've always avoided RF stuff. Weird things happen at high frequencies.
Is the '35' in the map() line a millivolt measure (from variable 'level'), or ? And, if so, are the diodes something other than silicon (whose typical turn-on is .7 volts?)? Just trying to grasp the magnitude of RF output from your hand-held. Thx.
This is exactly what I need! Thank you.

The lottery would be nice. Fixed income sucks, but I do enough side jobs to have a little play money.
>Being retired is great!
I hope to find out in a few years
+George Chambers Thanks buddy
I hope you do as well!

at 4:29 you can see the RF from the baofeng interfering with the video camera.

Oh, do Neopixels come in straight lines? This would be great with a couple of those and a servo. Make a 'working' replica PKE meter from Ghostbusters!
+Moonbrony Yes, you can buy rings, rows, and individual. Look for WS2812B led lights.
It's a high tech crystal radio!
+pileofstuff Indeed it is!!
how the two diodes and one cap catch RF signals....you said one diode rectify the signal, what does the other one do?and what the cap does?

+Are Jayem Values in the map function are arbitrary, and my diodes are silicon Schottky.
Very cool...
+J. Clowers Thanks
