NEW: Anybody know what these are? I got them from an rc plane.
this is the back:
This is a board of a different car. anybody got ideas?
the two outside ones look
the two outside ones look like transistors, but could be vregs. They should have a number on each that you can google.
the middle one…a crystal(resonator)?
outside one…can’t tell with the image…almost looks like a peizo buzzer though…
What were they removed from?
**I think **
i think the big black thing is one of those things that beep, or make noise.
I got them from a took-apart alarm clock.
Ty for the infos
yea, that’s the buzzer
yea, that’s the buzzer voodoobot was talking about.
NEw stuff
new stuff, pls reply somebody.

parts
1. ceramic capacitor
2. probable transistor
3. probable resistor
4. electrolytic capacitor
5. trim pot ?
6. inductor or coil
7. crystal oscillator
5 looks like a trim
5 looks like a trim capacitor or trim inductor
WOW
wow thanks for all the infos guys!!
now in your oppinion, what is worth using again, and how? (im a nooooob)

what does the bottom side of
what does the bottom side of the board look like? 3 could potentially be an inductor as well(as well as the top center green component). It looks like a simple single speed motor controller. Turning would be controlled by turning one motor off and the other kept on.
thank you
thank you for all the infos guys.
just a couple more questions, those ceramic capatators,
what are they for? I took them off a salvaged motor from
a rc car, and it didnt work anymore!

They reduce electric noise
They reduce electric noise from the motors. The motors should work without, but the electric noise can create problems for other electronics.
Ok…
But its not!
there also used to be something soldered on to that middle silver point. Maybe thats the problem?
I have seen some motors,
I have seen some motors, where there is a capacitor from one terminal to the motor housing and from the motor hous to the other terminal. + wires to the terminals. I don’t know, if that is better than just soldering the capacitor to the terminals.
It’s not clear on the
It’s not clear on the picture, but are the solder on the terminals touching the metal casing on the motor? In that case, you have a short circuit. Try to remove some of the solder and test the motor again
ah im no pro but ithink that
ah im no pro but ithink that "posible transistor" is a voltage regulator. just an idea
oops…
a short circut???
Great!
thanks by the way.

What do you mean with all
What do you mean with all those !'s and ?'s? That you don’t know what a short circuit is?
** nono, i know what a short**
nono, i know what a short circuit is.(its when power(electricity) flows back into a battery without being resisted.)
BTW: you were right Jka, it was one, i fixed it, and now it works!!!
thank you!
