scavanged chips
« on: June 24, 2009, 06:43:50 AM »
So I managed to salvage/scavange chips off boards I had taken apart.  I have a question about basically all of them.  The data sheets are as follows:
http://pdf1.alldatasheet.com/datasheet-pdf/view/47667/WINBOND/W29EE011-15.html
http://pdf1.alldatasheet.com/datasheet-pdf/view/69360/KEC/KIA494AF.html
http://pdf1.alldatasheet.com/datasheet-pdf/view/56093/ATMEL/AT27C256R.html
The questions that I have is that I have no idea what these chips do.  I am not an electrical engineer, while I am getting my computer science degree, there is not any electronics associated with it.  I am kinda disappointed at that, but what can I do.  I believe that the last chip will be of no use because it is a one time programmable chip and that unless it is performing the program it was made to do, it is useless.  Your help will be greatly appreciated.

Do or do not, there is no try yes I changed my picture, it is of my daughter.

Hi,

The Flash memory is a nonvolatile RAM memory (i.e. it retains its data when powered down).
The Voltage mode PWM Controller is a chip that can be used for speed control of a DC-motor.
The 32Kx8 OTP CMOS EPROM (so many acronyms, so little time ;D) is good for the product it was found in and for picking up dust - bin it before you forget how useless it is to any circuit besides the original - OTP means One Time Programmable, so no way of changing the data, hence no way of using it.

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?
Please remember...
Engineering is based on numbers - not adjectives

Same on you..... you dissoldered a mobo.... :P
haha.... It really feels that any mobo has this windbod memory ic.... :P
what ever....

That PWM thingy is really only an advanced 555.... worth keeping and playing with....
Still.... not so great after all.....
But can also be used as a regulator.... well not regulator exactly.... but you can build one with it... :P
For whom the interrupts toll...

Anyone still on this post? I'm currently attempting to begin in entry-level robotics without even completing my high school. I know nothing of what I am doing but tearing all sorts of things apart.

I need to know if I can connect the "Circuit thingys" to each other, and if I can, how?

Also.. How do I make my own post?

Also.. Is it safe to open a portable DVD player? Or a laptop?

 ;D Hello!
Anyone still on this post?
Yes, people are still on this post, even though it may look deserted at times. :'(
I need to know if I can connect the "Circuit thingys" to each other, and if I can, how?
Quite a question! :) Electronics is a science into itself, and takes discipline and time to learn,
like everything. If you want to jump into robotics, I would recommend going to Parallax.com,
and look into their basic stamps. Parallax has tech support, and schematics to support your
learning with projects
. Programming is easy and logical; software is friendly and fast. To get into
electronics itself, there are books on amazon. A visit to your local community college (if you have one)
to look at the electronic books there, or talk with an instructor. This should put you on a path of
discovery, without much pain.  ;D
Also.. How do I make my own post?
All this is in the instructions, posted in the forum. You may have to dig, but the info is here.

Also.. Is it safe to open a portable DVD player? Or a laptop?
As long as you do not have power to it, you should be ok. Caution, if your open these
items up, and do not have any idea of how they function(electronically), you may destroy
the units. If your objective is to learn, and destroying the items are ok, then I would get
a schematic (electronic map) of the items, and learn that way. You may be able to get the
schematics from internet searches, or from the manufacturer themselves. Use the model and
serial numbers to target the search.  Good Luck!!   ;D ;D ;D

Thank you SO much! Never used a forum site before either so sorry if I am kind of awkward with posts and replies. I will check out the site you suggested! Also I'm not sure what my college has to offer for robotics or electronics but will try there too. I'm pretty determined. I actually just made my own post on here asking how to connect all of my parts together, you should check it out! Have fun everyone and I hope one day to be a big contributor to robotics.
