Things To Scrap FOR ROBOTS!!!! -list items scrapped so we can spend more @ para
I thought it would be fun for us to get a list of things we scrapped
and got valuable robot materials from so that we can save more money
to buy sensors and and wheels and stuff from parallax [noparse];)[/noparse]
( this would be more useful for a non kit robot builder)
so aslong as its allright with the mods here List away!
feel free to add pictures, I used a scanner light as a way to type at night for a while
ill start with old VCR's ive got tons of stepper motors from them and
some useful gears and Metal plates and such for chassis implementation.
also 1 digital IR reciever - yay -

and stepper motors of course
supply that provides both +5v and +12v on a breadboard-friendly connector.
I've also scrapped a printer and got a few gears and bits of plastic out of that (the steppers inside were a real disappointment at 27volts.... 25v min to operate)... I wouldn't recommend
many printers for steppers unless you can generate a decently high voltage for them.
I also used gears out of an old Norelco electric razor and I'm waiting to use the rest of it (it has a 1.5v rechargable built into the board with the charging circuit and a very powerful motor) when
I come up with something.
Best thing I've scrapped so far was an old mouse... two IR/IR receiver pairs and 3 neat little tac switches, plus some various resistors and such.
I've also scrapped an old gameboy (nothing useful cept the volume pot), a solar-powered fan (solar cell kinda sucks), an ancient computer motherboard (DB9 connector, jumpers, ect) and
two old TVs (watch those high voltage caps! The wiring was good and the channel changer gears might be useful in the future... plus a TON of resistors)
With a budget of $0 for hobbies, I've found some rather unique uses for the junk around the house... you can work miracles with an exacto-knife and hot glue!

If a robot has a screw then it must be romoved and hacked into..
Lcd code : F-51405GNY-LY-APN
lcd mobo :X3689 LC
ill be interested to see if i can get it to work with the BS2

A Childhood toy, R/C Car which doesn't work. (I wish I didn't)
A mobile phone (Yay, an SD card reader, Camera, LCD Display and a vibrator motor? [noparse][[/noparse]Please don't think dirty])
A toothbrush (For the plastic and bristles [noparse][[/noparse]Attach the vibrator motor onto it with some coin batteries and it will become a bristle bot])
Anything else would you like me to scrap?
(This does not include my security system protecting my house)
My son looked at it. I told him I was going to make it into a Robot. "That is too cool to be a robot," he said. Needless to say, it is still an R/C truck...

In the end, it seems that it's all about getting the LEDs to blink....
A telephone wall jack turned out to be less useful than I had hoped... and a disposible cell phone was completely useless (all surface mount).
Cameras:
- panasonic M5
- Hitachi 2300E
- grundig (vhs-c)
A lot on interesting things from small geared DC motors to IR sensors, optics, components. The xerox and scanner gave me some steppers (4 phase) , IR , microswitches, encoders, steel guiding bars and other parts i can't remember now.

worked great (after cleaning of course) plus the usual collection of printers. and stuff.
p.s. I am looking for some more powerwheels to make an articulated 4wd bot....

* Stepper and other motors
* Driver boards/ICs for the motors
* Solenoids
* Shafts
* Bearings
* Solenoids
* Gears
* Clutches
* Sensors (usually I/R "Gap" Sensors)
* Switches
* Hardware, Plastic, Metal frames, etc.
* Wires and various connectors
* Optics
* Power Supplies
Manuals of varying levels of detail can be found or puchased online. Some service manuals have very detailed electrical infomraiton and parts lists. Others not so much, depends on the brand/model.
These are easier to come accross than you think. These things are very commonly leased, and by the time the lease is over, they no longer have any market value. Business normally have to pay to have them hauled away. If you put feelers out, and are patient, you can usually snag them for free. Also check with your local computer recycling center. You may be able to make a deal by letting them have some of the stuff with "recycleable resources" (gold contacts, etc.) and you get to keep the stuff that's "junk" to them.

Battery powered kids cars have some pretty heavy duty motors, wheels and speed controllers. Battery powered drills have gear trains, bearings and speed controllers. Power chairs have become so comonplace in robotics that I've seen used ones on Craigslist advertised as robot bases in stead of power chairs.
My best find of all time though, an old laser disk player, for the 12" disks. It has a great laser and an X-Y positioning system that's made up of 2 8ohm speaker coils attached to mirrors - not kidding. (go see http://cannibalrobotics.com/laserthing.htm on my website.)
The old 'ball bearing' mice have two really nice shaft encoders in them.
Electric car seats have really powerful worm gear drives.
Maybe a contest is in order? What if we collectively found some company ditching a whole bunch of scanners/printers, all the same.
Each team·would get,·the device, a·Prop or·Stamp controller board, an objective·and 2 weeks to deliver. They could bring tools and solder.
Junkyard wars on a micro level if you will.
Thinking outloud here, anybody in Austin want to help me organize that for high school competetions.
Robotics clubs are getting very popular...

One thing I did not see in the list yet is vehicles. I mean, its a heck of a thing to scrap but I am sure we have all been around a few that could be used as parts (maybe its just a redneck thing?). The motors that are used for the windshield wipers are great. Not to mention on newer cars and trucks the electronics that are available. Belts, gears, motors, plastic/metal parts and lots of neat 12v things... good stuff... lol
EDIT: Sorry CannibalRobotics, I just noticed what you said about using the electric car seat motors. Your right, those are great. After reading that it reminded me of one of my coolest endeavors. I was able to get ahold of one of the Rascal electric scooters. Pretty much brand new, but do to certain circumstances it could not be sold, so it became fair game for me. Needless to say I was excited.

WOO HOO!!! [noparse]:)[/noparse]
I saw a $179 power wheels Quad bike on the floor and thought Hmm That could make a Sweet Robo base !!.

All It needs is a speed con and a servo for steering ..
And lots of extra plastic removed LOLs
I remember scrapping my old one as a kid in to a giant RC Car ..
but it was still not a autonomous robot So I figure I should get one and
try it out again DARPA style with some stamps and not just a 75MHz AM Rec ..
Me I Hack Roomba bases for fun * looks at the 2 untouched Roombas in the dorm room *
I am on my 3rd ..
I reused some of there parts like the the drive system and the power system ...
I also reuse the Fets off Maxtor HDs to use for small devices .
I love to gut computer PSUs all kinds of goodys in there!

3 stepper motors (even found data sheets online for them)
2 DC motors
A 32v DC power supply
lots of optical interrupt switches
a 12v fan
a big shiney smooth metal shaft (that the printhead mechanism moved back and forth on)
some nice wheels (that were used to feed the paper)
lots of gears, springs, and stuff
I've got a old broken HP laserjet I plan to scrap as well.

Things like this are in craigslist, in the FREE section quite often. There are 14 listed right now in the Seattle area!

very cool and if worse comes to worse call your local high school's they often will let you have the old stuff they are throwing out well my town schools anyway I would try places like that and offer to carry away there old computer stuff I know most places have to pay to have the stuff hauled off, my local dump will no longer let us dump TV or computer monitors anything with a screen we have to pay a waste management company to take
