##### things that need to be Identified...
« on: July 04, 2007, 08:07:56 PM »
Ok, I opened up a toy walkie talkie and it has a lot of things on a board, excluding the speaker. there is a black thing (looks like a old watertower, only half of one) some orange round things, some tan hot-dogish things that have colorful lines on them (what do they mean?)- I believe they are called resistors, but I wanted to make sure- some black tall tube-like things that say 10v, and three wierd things: a large silver rectangular box (connects to a button) that says DC, an orange thing that has a red ?tape? around it and a silver thing that is like a box with 24 sides that contains it, and a large copper tower thing with copper wire around it. If you could I dentify these for me, then tell me if I can salvage them, I'd be much obliged.

can you get us a picture?

half of water tower is probably a transistor.
yes the hot dog things are resistors
the black tall tubes are probably capacitors. shold also say XXuf on it
the rectangular box is probably a switch
sorry

Resistors, transistors, basically everything I listed above.

megaman - the wires used in these electronics is usually pure gold, but that is not the best part... it is what's inside that is really cool... resistors, for example, use rare natural diamonds!  You should rip those things out of the walkie talkie and bring them to a reputable jeweler... I bet they are worth a fortune!

lol not really, 99% of eletronics use cheap and easy to find materials..

A lot of stuff uses copper, sometimes it uses silver(most conductive really) or gold.  both are SUPER conductive..  Gold is VERY popular in computer parts, such as proccessors..

Its not worth much though, even if you melted down all the pins from a hundred proccessors.. it wouldn't be worth crap.

If I wanted to make the wires longer/ replace would I have to use the same material? or could I, say, use copper if it were gold? would it still work?

ya it would work...

Most of those shouldn't need to be extended though..  and to be honest, for the cost of wire you could buy most of those parts

while it is true that different metals conduct electricity at differing levels of "efficiency", for you what you are trying to do, it will make no difference.  You can use any type of wire that conducts electricity.  I strongly suggest you get your self a beginners guide to electricity and electronics before you do anything.  There are many good tutorials on the web.

LOL maybe you should read up on electronics yourself! I'm not exactly sure where you got the natural diamonds idea, unless you consider carbon graphite powder diamonds... Resistors are mostly made from carbon powder mixed in a ceramic composition, then coated with a plastic resin, no diamonds here. And as for them being worth a fortune.. WTF! That doesn't even make sense, if companies make and sell resistors for pennies a piece, why wouldn't the companies sell them to jewelers themselves??? Think about what you say before you say it.

he was being sarcastic.

here are some books for you to read.
