Tunable Foxhole Radio



Uploaded by: utahike
Video Description:
My 10 year old son worked long and hard on this thing and finally got it working. He is able to pick up about 15 stations. This thing is pretty cool.
He won first place at his school and district science fairs. He placed 3rd at regional. Pretty cool indeed.

You have made a great radio!! I use to listen to one like that when I was younger, I could hear long distant stations at night from Canada, I live in Georgia, USA. but I used a diode 1N34A, instead of pencil lead and razor.

No power supply needed for radio itself. If you have earplugs you can hear without power. We did use amplified speakers for this demonstration. Thanks.

You should build one. I will admit that I didn't think that it would work. But when my sone fired it up, and it tuned in to a news channel...Well...I was baffled and shocked. I never would have figured it was so easy to make a radio.

Do a google search for retro-ww2-foxhole-radio and you should find one on the gizmodo site that is very close to this one.

I will make one. i just need some magnet wire. but did you need to "blue" your razor blade?
We used an ... ( 1 month ago by utahike)
We used an authentic WWII blued razor blade. If you do not have one...you simply need to oxydize the blade. Put it in some salty water for a couple of days....or easier, heat it with a torch or a gas stove until it glows and let it cool. Magnet wire is really easy to get...just go to radio shack and ask for it. Or..simply wind some solid core bare wire around the tube and spray it with varnish. This creates a thin barrier to stop it from shorting out.
Let me know how it goes.

does it work in the day time? Can it catch a station 25 miles far from my house?
Back in about the ... ( 2 weeks ago by NotOfThisGalaxy)
Back in about the 1930's, an old friend of mine's brother made something just about like that. Down at the 'ol fishin hole, he winded up some wire on a hog-wire fence, & connected a speaker to it. They could listen to the farm report & music on the ONE station in that part of Idaho. Bill Hall was his name. I don't know his brother's name; but the brother later invented the phased-lock-loop circuit in his garage. Bell Labs stole it from him. It is the crystal timing part of the PC.
