Introduction: Upside-down Glasses
Step 1: Download and Laserize
If you just want to get yourself a pair of perspective flipping goggles, all you have to do is download the file, arrange the parts to be cut (being sure to include two earpieces, they're identical, you know) and laser cut yourself a pair (mirror side down on the plastic, please.) It's pretty simple.
What those of you without laser cutters (poor souls that you are) may take away is this cool construction method I learned from puzzle maker Lee Krasnow. I measured my screws, nuts, and washers, and modeled them simply in cad. I measured the width of my plexiglass. Knowing those dimensions, I could make some tabs in the design. When the design is put together, the tabs keep the different panels aligned and square to one another. the screws fit down through the holes, and connect with the nuts in the adjacent panel. The nuts are held fixed by their tight fitting in the plastic. Putting these together is a breeze, really.

Step 2: See?
These are just a fancy version of holding a mirror underneath your eyes and looking down into it. The effect is pretty cool, but the design could use a little more tweaking to be perfect.
I went through a lot of revisions in the design, testing and prototyping the model before reaching a final product. The laser cutter made it easy to test new revisions on the spot.
Step 3: Cool.

Hello,
that text you made was incorrect.
This does not rotate 180° on the Z axis. Instead, it would invert
your Y scale from 1 to -1.
This being said, you would have to have the text in correct order, but upside down.
(For example: '¡ןooɔ' would be 'cool¡')

Nice job but a lot of extra light into your eyes and very
small field of view.
Among scientists this device is named invertoscope.

wear them constantly for 3 days and your vision will correct it by flippin it over

heh, maybe you are just weird! jks jks man. My dad told me that one. and some people's vision flipped
Reply 13 years ago on Introduction
ya, if you were them constantly, like never take them off, for long enough your mind will flip the image in your head and you'll see normal. then when you take them off, everything will be upside down until your brain resets it. they did this as a psych experiment once. i wish i had a laser cutter to make a pair and try it myself

(btw, after some research, i found out its waaaay better to use some prisms from binoculars, much more sight and you don;t have to look down)

Haha! Cool! Awesome attempt, Eric! You were so close! I'm just curious - where does one go to get acrylic sheets/ mirrored acrylic sheets? (Other than the Instructables Supply Shelf....)
Reply 14 years ago on Introduction
usplastics.com it's called reflective acrylic or mirror-backed acrylic. Something like that.

i think someone with a steady hand could cut these out with a small saw. You don't need all the tabs and grooves; they could just glue them together with the right angles. You might also try uploading the design to Ponoko; then people can just order them directly, from there...

I cannot open the pdf file with instructions. I see you did it. Can you email me the instructions as attachement? Thanks in advance. Bub bub@buroojongerius.nl
