Make your own White Noise Machine

Filed under: Do-It-Yourself — cygnl7 @ 6:23 pm

One of our sons has a hard time sleeping.  We’ve tried lots of things.  He’s been through a sleep study, tonsils and adenoids were taken out, diet changes, etc.  Next on the list was white noise.  However, I didn’t want to spend the money on a white noise machine.  So I made my own, complete with a clock and an FM radio!

But first things first.  We tried tuning his FM clock radio to static.  But wow it’s hard to find clean static these days!  If you’re in a place that doesn’t have a lot of radio stations then this will probably work.  But for us it didn’t.  If it’s not clean it doesn’t help.  It becomes distracting.

So, I decided to make my own.  It was quite simple, actually.  I bought a cheap Sony alarm clock ($10 at Wal*Mart).  When I got it home, I took the screws out and opened it up.  I found the AM antenna (it looks like a small dowel wrapped over and over in fine copper wire), freed it from its screwed-down confines, and proceeded to cut the wires that lead to the antenna.  I wrapped the cut wires up with some electrical tape so they wouldn’t be dangling around inside waiting to short something.

After all that I put the radio back together, plugged it in, and turned it on.  After switching the radio to AM, all I got was static!  And the great thing is I can change the “feel” of the static from brownish to pinkish to whitish by tuning the dial.  (I use -ish because it’s not truly brown/pink/white noise, but close enough.)  Anyway, so far it seems to be helping.  /me keeping his fingers crossed!

(Disclaimer:  Don’t try this at home.  And if you do and it doesn’t work or causes some sort of damage, don’t hold me liable.  I’m just relating what I tried.)
