Hi,
heres my dilema, I have a AC 12 V source which I need to convert to
about.......lets say, DC 5 volts I guess.
Anyone know how I can do this

Few diodes, capacitor and a voltage regulator is all it takes.
You can buy the components at radio shack.

Such a dilema (or even dilemma). Hmm. Use the 12 V ac to boil water.
Collect the steam, direct into a piston engine. Belt the engine to a
water pump. Pump water up a hill to a large reservoir. Build a penstock
out of PVC pipe and direct it to a hydraulic turbine. Use the hydraulic
turbine to turn the shaft of a dc generator shaft. Regulate the output
of the generator with a carbon-pile stack connected to its field. You
can make the elements from the carbon pile stack by cutting disks out of
the centre rod of a common No. 6 dry cell.
If anyone knows a simpler way to accomplish this, I challenge you to describe it.

( a few parameters would make this more of a proper engineering question. Don't they sell those "101 Electronic Projects " books on newstands for $3 any more? )

Attach a fuel cell to your butt; connect the fuel cell to a rechargable
battery. Every time you fart, the fuel cell produces current at the voltage
you wish and charges the battery...

Boy did you date yourself! I'll bet the youngsters out there never saw one
of those. They don't exactly fit into a portable MP3 player!

I'm a youngster! (Well, 26 anyway).. and yes, I've never seen a No. 6
dry cell, but have heard of them. What exactly are they, and what are
(were?) they used in?
I'm only familiar with AA, AAA, C, D, N and the ever-handy tongue-testable 9V. }:)

The were/are 1&1/2 volt dry cells about the size of a small thermos. Used
most often in groups for doorbell/call systems in old apt. bldgs. - larger
homes - etc., and other signaling uses. I have also seen (in the past) them
used for lighting infrequently used closets, and storage spaces in
combination with door switches.
They were also quite often used in training facilities for powering training boards (switches, lights, and other devices) before low voltage power supplies were commonly available.
I believe the chemistry was Zink Chloride?

A set of No. 6 cells would run your MP3 player for a long long time. I
once had a bunch of these for use with telephones - though of course not
telephones connected to the phone company.
A few weeks ago it occured to me that the portable set playing quietly in the corner of my home office was possibly the first time my nephews and nieces had ever seen a black-and-white TV.
To prove your antiquity, what are these: 50C5, 35W4, 12AU6,6BE6, 12AV6.

Those are modern vacuum tubes from an "all american five" radio circuit. I restore sets that used some of the earliest ones.
