Secret Safe From Old CD's




About: Innovative Projects, Diy's, Life Hacks

CD's and DVD's will soon be joining VHS and Floppy disk club.

USB pen drives and on-line storage have replaced optical data storage.

Don't throw away those old CD's or DVD's. There might be be another use for them.

In this Instructuble, I made a secret safe from old CD's/DVD's.

Step 1: Draw a Circle

I used "cake box" type of case full with different CD's/DVD's.

I put a small 8 cm CD on top of other CD's and used it to draw a circle.

Spindle cake box was very handy for the procedure.

Step 2: Cut the Cirlce

Then, I cut out the circles.

If you have mixed CD's/DVD's, you'll find that some will be easier to cut than others.

Step 3: Glue Them Together

I clamped them together and glued the inner sides with epoxy glue.

Step 4: Make a Lid

When glue was dry, I trimmed upper part of the hole to fit the small CD.

Step 5: Make a Lid

To make sure the lid is not see-through, I used a permanent marker to colour the small CD.

Then I glued a normal CD on top.

Step 6: Make a Lid

I removed the spindle and cut it shorter.

One end was covered with the painters tape, so it would not slip through the CD.

Other end was glued to the CD.

Lid was finished.

Step 7: Fix the Bottom

I glues a few CD's at the bottom of cake box.

As there was a hole from the spindle, I covered it with a piece of plastic (from another CD) and more CD's.

Step 8: Put It All Together

Then I glued the ring to the cake box and used felt to make the safe look neater.

Your secret safe is ready!

    Good idea but I can't do it lol.

    Thanks for this though :)

    Might be more hepful if you explain how exactly you actually cut the discs. I don't understand how you did that part really. Tbh "cut the circle" (step 2) lacks any actual instruction. You only tell us to do it, and mention some will be easier than others....

    Otherwise a really good idea & I like it. I just cant make one yet because I've definitely tried cutting into a disc before, with a pair of sharp scissors - a couple times - & it's never really worked for me. Mostly I dont understand how you cut out the inner part without cutting/breaking through the outer edge. Seems impossible!

    Instead of manually cutting each and every CD, is there a way you could do this will a drill press hole saw?

    I've been meaning to do something like this (maybe a cryptex, for a somewhat creative gift) with around 3.5 kg of various worthless CDs and DVDs I piled up over the years, but I really feel like there's a smarter way to go about doing this than cutting them individually and manually. However, I'm just starting out with DIY stuff, so any kind of advice regarding the aforementioned problem would be greatly appreciated.

    Other than that, nice 'ible!

    It looks need and you did a very good job.

    One small issue:

    I'm not sure if a hiding place around CD's, is safe enough (putting in an usb stick!). As we all know CD's could be used for files and data, which you want to hide at the first place. So if someone is looking for data to steel or look in, he will look there as well.

    I do agree that no one uses them any more, but now you give them a suggestion, so why not look there.

    I guess it depends on what are you trying to hide. Sometimes students have problems with the missing money, so it could be a place to drop a spare change.

    It's true that now it's not a secret safe any more, but at least it's not as popular as hiding your money in a sun cream while at the beach.

    Everyone has seen it.

    I don't think this will become too popular as it requires more work to make it :)

    Very creative, I love it!

    When you cut the CD/DVD discs, did it create a lot of 'flakes' and a mess or was it better than if you break one? :)

    You were able to cut them with just a scissor and they did not crack and break?

    Yes, I only used scissors. Some did crack and break, but I had extra CD's.

    It also depends how you cut them. I started from the centre, cutting spirally.
