OK. Let me try to explain this...
I have a trusty Maxell P-13 FM transmitter.
Not the greatest thing in the world - but it's
teeny and is a very good point to point transmitter
for in the house.
I used to have another one but I destroyed it.
Here's what happened. The P-13 uses 3 AAA
batteries. They last a while and then they run
down. I thought I could attach some wires to
the battery terminals. Then I could run those
wires out to a power source that would last longer.
Such as - 3 D batteries in their holders. The voltage
would be the same. It would run a lot longer. Heck -
there isn't even a power supply involved here. It's
just some bigger batteries. I sounds like a good idea,
right? The transmitter would just take the current it
needed and go for a longer time.
Like I said before... Right?
Well, no. It didn't work out that way.
I hooked up the batteries and this particular
P-13 never worked again. (The polarity was
correct. I'm assuming there was no reverse
polarity protection on this kind of item.)
It was as dead as a door nail. (Whatever that
means.)
One trusty P-13 into the wastebasket.
My friends said that shouldn't happen. I
agreed. And then I thought - the device's
teeny chip (surface mount, whatever) countn't
handle the high inrush currect. It just wasn'ty
designed to do that.
But I didn't quite believe the above. And I
actually blew up a few other small devices,
some good MP3 players and such.
I have to go.
What do you guys thinK.
