video Make An Infinity Mirror!
Infinity Mirror Illusion.

Extremely simple concept with stunning results.

The illusion may look complicated but it was really very easy to make.

Details of materials and construction for Infinity Mirror Illusion
The sizes and measurements i've provided may not be 100% accurate. Feel free to experiment with your own materials and measurements.

1 - 7" Cardboard lid 1 1/2" height
1 - 9" Cardboard lid 1 1/2" height

1 - 15 bulb LED light strand

1 - 7" diameter mirror
1 - 1' X 1' 1/10" thick plexiglass or real glass (whichever you prefer -- real glass will give a cleaner result)

Take the 7" Cardboard lid and mark a spot every 24 degrees on the outside rim halfway between the top and the bottom.
That will create 15 marks around the lid for the LED's

I used a hand drill to create the holes for the LED's. Make the wholes a little smaller than the LED's so that they'll fit snug

Push the LED's into the hole. Push them in far enough so that they visible from the inside.

Cut the bottom of the lid out.

Glue the mirror in the middle of the inside of the 9" lid.

Place the 7" ring with LED's into the 9" lid. The small ring should sit directly on top of the mirror.

Cut a piece of mirrored window tint and apply it to the plexiglass / glass.

Attached the plexiglass/glass to the top of your lids.

I used duct tape to hold the glass to the cardboard lids then cut black construction paper to cover the sides and back.

I cut a ring out of silver construction paper and placed it on top to hide the duct tape.

I used velcro to hold the battery back to the back or the top of the infinity mirror device.

Good luck!

Plastic cutting jigsaw blades can be found at most hobby shops, Lowes, Home Depot, etc. I have seen where you could use a mirror and a one way mirror but this method is much more affordable.

I made this over the past week and I'm very pleased with the outcome! I had a very hard time using the lids though and creating a structure that would support the weight of the glass and mirror. I would recommend using a premade round object with glass (likely a picture frame or clock) to avoid this struggle. Very fun project with a minimal price involved.

I sent the author a PM but figured I'd post this here as well...anybody have any idea how he cut the plexiglass sheet down to a circle? Laser cutter? Jigsaw? I've made some smaller, square infinity mirrors by scoring plexiglass with a hobby knife, lining that up with the edge of a table and hitting it with a mallet to get a nice, clean break - but clearly that won't work for a circle, and I don't have access to a laser cutter.
They do sell special jig saw blades for cutting Plexiglas, I used them and they cut great, with the jig saw you should be able to make the circle cut. I purchased mine locally, but the are on line @ plastic supplier sites.
draw the circle on the plexi, cut a square width is the diameter of the circle, cut lines for the corners so you have an octagon, then file down / dremel it.

for this job its not so bad as the corners are covered.
Unfortunately I didn't have a dremel or a file handy (really need to pick up both)...see above comment for how I wound up doing it. Thanks though!
I made this today, for a cost of $10,00. Yes, I had some LED lights laying around. Best advise when you cut the plexiglas circle use a jig saw. I have a variable speed model so I started out real slow and used a fine tooth blade. Take your time. I cannot stress this enough. Let the saw do the work for you. I hate to sound stoopid (or imply you are not stoopid, you can't be, you are here) , but I have seen people use a jig saw and think, "If I put a lot of pressure it will cut faster." HA! If you want the circle to turn out like a circle, take your time. Unless you are on a time schedule, you have all day to cut a circle. I cut a plexiglas circle from material I purchased at a second hand store. Any 'rough' edges can be simply sanded off,
Yep, I wound up using two different approaches to see how they would compare:

The jigsaw really wasn't that bad with a fine-tooth blade and a slow cut.

where did you get the mirror tint? I have no idea where to look for it. The internet has too many different things.
Any decent sized automotive supply store will have small rolls of the stuff for about 10-12 bucks. Pep Boys, Autozone, etc. Home improvement stores also carry it usually but their rolls are bigger and about 30-35 bucks.

I made one of these today. I drove by a place that does 'custom' window tinting. I asked for scraps, and they showed me a garbage can and said, "Have at it." O.K. I got it for 'free' but bought the tech a cup of coffee, so it cost me $1.65. I ended up using three pieces (I made a larger mirror) but the seam does not show with the light on. In fact, the slight overlap was not noticeable. Try that.
I found some at Home Depot in the Window section. I got a large roll big enough to cover 3 windows for $30. I went on a massive scavenger hunt for the stuff and that's the only size roll I found and the only place I found that had it. Good luck on your hunt!

What if the back was a one way mirror too? :o
you couldn't look through it!
I was intrigued by your question so I decided to test it out with my own infinity mirror, whatever was on one side of the mirror also repeated itself making it to "infinite."Personally one one way mirror has the best results.

EPIC! nice job im doing this.

I'm trying to find out how to do something very similar that you may be able to help me with. I want a picture frame that when the light is off looks just like a regular mirror, but when the lights are on you can see a photograph inside the frame.
you could use a one way mirror (I'm not sure it's called like that)
and put tiny LEDs on the inside of the frame, so if you turn those LEDs on, you can see the image.

I don't think you can control it by the external luminosity, to see if there's a mirror or not, you need light, more or less, but you need it.

where did you buy your light strand from?

how much time does it take?
longwinters2 years ago
easy question for you, did you half the distance between the back LED and the mirror compared to the distance between the two LEDs ?

Nice project thanks for posting it.
just wondering where you got your mirror tint. thanks

For a clock, one could etch the numbers on the back of the mirror with backlighting and drill a hole for the clock module...

It would be even cooler if you made a mechanism that would make the LEDs spin
You could use a light set with a multi function module atatched
you can lid leds by order with a small controller :) actually I liked the idea :) I`ll give it a shot :) thanks

Thanks,for posting this, I have already made but I still not finish it, and thanks for the idea

I had to use a clock frame and no mirrored window tint but still looks cool. Thanks!

Very awesome. I wonder... with some small LEDs, I bet these would look neat as the eye pieces for some (Steampunk?) googles, or the eyes for a Halloween skull. Good job.

does the side of the glass with the mirrior tint go in facing the led's or outward towards you?
Facing the LEDs.

I dont really get it ,it's like if the plexiglass had a mirror face and a transparent face like in interrogatory rooms

hey yeah could i use el wire in difrent colors to make the strgate effect of going thourgh a worm hole
5/5 That is Amazing! It looks complex but its really not!

oh and i rated 5* for you ^^
you just gave me an idea..when i buy my own house, i am going to make a larger version (huge as in few meters square) it is going to make the house look big
