Ever wanted to smash a CD ? Why don't you just spin it and see it shatters !

CDs now are just an old technology, we got fascinated by CDs when they happened to be the #1 media storage medium, but technology is running fast enough to make this medium old and unreliable as it used to be , we barely use CDs now BUT we got a huge amount of CDs that we wanna get rid of ! so I wanted to make this action enjoyable and satisfying !

Step 1: TEST TEST TEST !!

I wanted to check how its like to spin CDs super fast using a vacuum cleaner motor , I removed the vacuum propeller and mounted the CD on the shaft using a nut, I placed that in a box and covered it with an acrylic sheet to prevent injuries to happen by the small flying pieces ! ( be very careful when doing so, never take off your safety glasses)

Step 2: BAAANG ! ITS WORKS, SO LET'S BUILD THIS THING !

well, I tried to sketch how its gonna look like , and collected the materials that I need for building this machine!
I found this metal from a junk , it used to be desks before !

SAFETY FIRST !! PLEASE use welding mask or goggles to protect your eyes so you can be able to use them after this project !

Step 3: WELDING

actually this was my first time welding metal and making such thing! I've learned a lot during this process, it didn't look perfect but I was happy enough with the result !

Step 4: WELDING DONE! WHAT'S NEXT ?

welding done, skeleton sprayed, the vacuum motor is mounted at the upper part , got a transparent polycarbonate sheets [it's super strong material that can't be cracked by shattered CD pieces]

the tricky part was the CD mount on the motor shaft. I tried to use different kinds of nuts but mounting the CD was taking a long time using a wrench to lock and unlock the CD, then this guy helped me with lathing a piece of metal that can be fixed on the shaft that holds the CD and can be tightened by hand "any other suggestions are welcome" !

Step 5: FINALIZING

wiring is done, there were a dimmer, led strip and the motor itself

4mm wood sheets are used to cover this baby ,

I designed the logo and laser cut it, placed a safety launcher switch and a push-on button to run the motor.

Step 6: ENJOY !

This machine was exhibited in the Jerusalem Mini Maker Faire and Musrara Mix Art Festival

Enjoy

<p>Very cool - way to usher out a technology with a bang!</p>
<p>Ooooh, and I so want to collect cds to make an art project, but don't know anyone that has any. Boo Hoo.</p>
That looks like a really fun build. I wonder if adding a switch to slowly increase the speed of the motor and a strobe light at just the rught frequency would &quot;freeze frame&quot; the disk as it starts to distort just before it explodes...
<p>There's a nice video from the Slomo Guys exploding CDs: <a href="https://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjtnrWx9KTKAhWI3iwKHcIPDCIQ3ywIJDAA&url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dzs7x1Hu29Wc&usg=AFQjCNF9XO7do2KS86eIxoUkm6VJmAk6ew&sig2=OGTk0PsTKfA8Y222_NNtag">https://www.google.de/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=1&amp;cad=rja&amp;uact=8&amp;ved=0ahUKEwjtnrWx9KTKAhWI3iwKHcIPDCIQ3ywIJDAA&amp;url=https%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Dzs7x1Hu29Wc&amp;usg=AFQjCNF9XO7do2KS86eIxoUkm6VJmAk6ew&amp;sig2=OGTk0PsTKfA8Y222_NNtag</a></p>
<p>this sound cool ! i actually got a potentiometer to control the motor speed , but i placed that in the wiring box underneath </p>
<p>That looks amazing! How fast were the CD's spinning? </p><p>Have a great day! :-)</p>
<p>i checked with an rpm meter, normal CDs take less time to explode, DVDs and dual layer CDs take longer ! but its something around 23000 rpm </p>
<p>Awesome! If you ever get a chance, please take some slow motion video of a CD exploding.</p>
<p>well i actually tried but i need a super slowmo camera that i cant afford :/ </p>
<p>TeamPanic is refering to this</p><p>https://www.youtube.com/watch?v=zs7x1Hu29Wc</p>
<p>If you want to watch a CD being spun to oblivion, then check out the Slow-mo guys on you tube. All their videos are awesome! https://www.youtube.com/user/the<b>slowmoguys</b></p>
<p>Wow cool. I have seen that before on YT but making a machine of it is great. I guess people would pay for that on fairs (not only on a maker faire).</p>
<p>yeaa thats it i wanted to make a machine only for this :D</p>
