Since regular DVD rewinders are so expensive I designed a simple cheap DVD rewinder you can make yourself.

Step 1: Parts

-A motor
-Some Tape
-A Small Cardboard Box
-Some Wire
-A Battery


<p>Nice product, now when we are at the DVD subject, I like to know if its possible to delete a allredy DVD/ CD or Blu-Ray write only disc, so I can keep the disc but delete the files, and it still looks like a new DVD? <br><br>I collect discs and build lighting fixtures from them, but some time i get discs with files on that i dont want to be read again, thats why i like them in the same condition as new. </p>
<p>I imagine if you spin the disc fast enough, the files would fly out of the sides because of centrifugal force!</p><p>On a more serious note though. I imagine it's possible to write something uniform across the whole disc. Imagine you write a 1 to every memory location on the disc. Not only would it render the information on the disc unreadable; it would also give the disc a uniform color - (I know for many CD's and DVD's the written area is darker than the unwritten area). There's a program called DBAN (Disc Boot and Nuke) that does something like this for hard drives, it might work for disc media.</p><p>Going from your picture, your works look very nice. Good luck!</p>
<p>I just wait until midnight, then play it &gt;&gt; Forward. Since the world is now upside down, the DVD is in essence &quot;&lt;&lt; Rewinding. The next morning it is freshly rewound. Ta Da! </p>
<p>I clicked on this just to read the comments, needed a good laugh!</p>
<p>Finally, a product I can&rsquo;t use. I already have too many gadgets and gizmos that occupy my time. Thank you Magnelectrostatic. What a relief.</p><p>No, but really, I applaud your creativity.</p>
Cool project but doesn't do anything just spins.
Finally, I can re-watch that copy of Titanic I bought YEARS ago. Thank you, sir.
wtf is it a joke or are you serous
I am completely serious. I know it may not look good, but it does work just as well as any name brand rewinder.
smart@$$ DVD re-winders are not real or are they what theirs a giltct in the matrix mom!!!!!!!!!!!!!!!!!!!!!!!!! you cold just open up the DVD player add wires to the motor then hook it up on to a battrie and switch right
You don't notice it as much as with tapes, but if you rewind your DVDs you find they start much faster.<br><br>It's not a well known problem, it's because the laser read head inevitably changes the polarization of the media when you play it, and the next time you play it the drive has to undo that before it can read it. Some expensive DVDs have dual heads and don't have this delay, but not the cheap drives most people have.
your all crazy
*Ahem*<br>I believe you meant to say, &quot;you're.&quot;
I am very concerned over the usage of these DVD rewinders. I had a pet mouse that started growing another head. This made me very concerned. <br><br>After heavy research into the cause of his misfortune, I determined that the radiation emanating from the DVD rewinder sitting next to his cage was the cause of the problem. <br><br>You see, the way digital media is recorded onto the DVD surface can cause some of the electrons in the inner orbitals of the medium's atoms to jump to higher levels whilst skipping the normal pattern of filling in the lower sublevels. Hence, when the DVD is rewound on a device which does not have a built in mechanism for radiation dampening, the abnormally high frequency of radiation the electrons release when falling back into their original orbitals emanates freely in all directions from the device. It is a little known fact that all commercial units sold are required by law to have this radiation dampening mechanism in place. The radiation, as my mouse would attest to, causes mutations in DNA.<br><br>So I would caution anyone in making/using one of these DVD rewinding deices to first:<br>1. Check with local laws to find out the ordinances governing the usage of non-radiation shielded DVD rewinders.<br>2. Make sure any usage of non-commercial DVD rewinders is limited to an area where a living organism (such as my mouse) is not within 42 feet of the unit while it is rewinding a DVD.<br><br>A probable fix fo this, however, might be to coat the DVD in marshmallows before rewinding. It has been suggested that the abnormal frequency of radiation emanating from the rewinding DVD is of such a nature that the atoms in the marshmallows can absorb the radiation before it can escape into the surrounding environment. In turn, these marshmallows can serve a dual purpose in that they will then glow in the dark after exposure to this radiation - hence a new and greener source of kiddy night lights might result from all of this.. <br><br>However, I have not yet been able to test this theory... any takers?<br><br>in summary: The results can be disastrous if the above cautions are not taken to heart. You see, my poor little pet mouse is now living a life of misery. You would think the old adage &quot;two heads are better than one&quot; would apply here, but he has found this not to be the case. Why? His main problem is that every time the new head tries to sing &quot;Home on the Range,&quot; it is always a quarter tone flat. So my mouse can never again give a non-dis-harmonic voice recital! All this b/c I failed to shield my home made DVD rewinder.<br><br><br>
The problem here is the mouse was closer than any other conductor. If you substitute the mouse (conductor) with other types of conductors, you could find some really interesting results. For example, a frog will not grow another head but will instead have tadpoles within 12 hours with multiple heads.<br><br>If you notice the warning label on the bottom, it states you must keep wives and girlfriends at a distance during operation, else she may also grow another head. This could be bad. However, if you reverse the polarity...
AHA! That explains it! After spending the weekend with me (well - he WILL have spent the weekend with me in about 5 years) my young nephew (not born yet - see your later [?] post about using this mechanism for time distortion - you see - I did it - or - will have done it - or will do it already - depending on which direction you look at the problem) was bit by a strange looking red and blue spider the he found even closer to the mechanism than my pet mouse (BTW, I changed my mouse;s name to Zaphod). After this happened, my nephew started (will have started, will start, did start - see above note of time distortion), literally, climbing the walls (and spinning webs).<br><br>So I am assuming that the spider actually must have been closer than the mouse and somehow had its arachnid DNA mutated to impart these special abilities to my nephew Peter. <br><br>I really appreciate this forum where I can learn so much from other people.<br><br>BTW - cute baby pic!
why bother, we are all time travelers traveling at exactly 60min/hour threw time.
I noticed you used a 9v battery. It's the fact that this is so portable that makes it so handy. But what I think may really be happening is it is not 'rewinding' the DVD but is actually reversing time in very small increments.<br><br>I'd like to see this theory tested using a power inverter and a 500v power source. Of course you would need an appropriate diode to prevent it from accidentally going forward in time.<br><br>If this theory is correct, then it is only the device and DVD that are moving in time, and not its surroundings. But with some creativity, you could expand the area of effect. However if everything went back in time and not just the DVD, we wouldn't even notice that it had worked.
Fascinating!<br>And such a time diode could possibly be fashioned out of a zucchini and some dry ice?<br>The possibilities are endless!
absolutely epic
This instructable will work wonders at my job, and perhaps let us cut out staff in half (work at video editing department for promos) But I am concerned that your not actually rewinding a CD or DVD in this picture but one of those AOL frisbees/ drink coaster that are cleverly designed to look like a CD but arent good for much else. Will this work on rewinding REAL CDs/ DVDs?
To be quite honest this works on anything that fits. CDs, DVDs, Blu Ray discs, tires, and most other things within our dimension. (things outside of time won't work)
crap I have a few of the new 4D Blu-Ray disks that need to be rewound.
Would this work for BluRay? L
Just replace the battery with a car battery. BluRay contains a lot of extra data, so it takes longer to rewind. If you wire two car batteries in series to get 24V the motor will go a lot faster. It may damage the motor though; do at your own risk.
Thank you for the update. L
Lemonie,<br>Last time i checked, sony was about to release their own branded rewinder specifically for blurays. Until then, i wouldn't mess around with the blurays, just do it by hand. You don't want to mess up the magnetic tape inside.
<br> No you don't want to mess up the tape, it can be horrible...<br> They should rewind a whole disk in what? a couple of minutes?<br> <br> L<br>
Japan apparently just got it down to 23.86 seconds!!! I am looking forward to this.
<br> ! well that's progress for you.<br> <br> L<br>
I was wondering, would it be possible to make several of these and stick them in some sort of casing, or even stuck on a piece of wood so i can rewind many dvds at once?
That's genius! With the right sort of case it could be a classy DVD rewinder as opposed to a ghetto one! It's definitely possible.
can this be used to fast forward dvds if you just switch the wires to the opposite terminals? i know that normal dvd players do this for you but i want to be able to watch dvds at the same time
Technically yes.
never mind. i just realised i can just put the dvd on the rewinder upside down to make it fast forward
Ahhhhh clever! I always use to roll it down my street, hours prior. This will save so much time.
I Dont Get It...... DVDs dont need to be rewound.....
really? or are you being sarcastic?
Seriously, Whats the point of a dvd rewinder? DVDs never need to be rewound, once you watch a movie you just go back to the title and then press play to watch the movie again.
What kind of DVD player do you use? I want to get one.
I think he's talking about the movies they have playing in the dvdplayer/tvs at wallmart. The trick is they don't say it needs to be rewound, and they just make reallllllly long move where half way through, it goes to the &quot;menu&quot; and starts again. I use to work there and had to go around with one of the retail re-winders and rewind them every hour or so.
It's a joke<br />
Errr... You don't need to re-wind a DVD. You know that, right?
come on man. it’s a joke.
I was just checking, it looked like so many believed it...
if that were the case, i would have to give up on society completely. it would be like that movie idiocracy, ha
You kidding right micro? Hahahahaha, Ohhh, i remember when i had to do this too! So glad i just got a new one that auto-rewinds!
All the newer DVD-players rewind automatically. That's why there is a small delay when you open the tray. It first has to rewind the DVD. Still, this Instructable could be of use for someone that has one of the really old players. They were notorious for not fully rewinding or even not rewinding at all!
LOL, so true. I finally gave up on my old DVD player because it had that problem. I'd have to stick a pencil through the hole in the middle and spin it for like 5 minutes to get it back to the beginning. Annoying!
jeff-o, you are showing your age LOL
