This Instructable covers building my available Full 8"x8" 32 LED Infinity Mirror Kit  or re-create it with your own materials such as acrylic  or hardboard sheet. It also could be scaled up or down to suit. Plans are included in the ZIP below.

The Kit contains everything needed to recreate this project. Everything from high-quality glass mirrors, parts to build a durable plastic frame, 32x LEDs( color's are buyers choice), LED Controller kit, DC Jack, Wall-Wart Power Supply and wire. Just supply some spray paint and a few tools.

With an overall dimension of 12" x 12" x 2.25" and 32x 5mm LEDs with controller.

I can also put together custom kits, if you would like to supply some of your own parts or if you want some of the steps/parts built for you. Just PM me or Contact Me

If you would like to re-create this project with out a kit. There is a diagram in the ZIP below with info on the pieces required to build the frame. Acrylic, Hard-Board, Wood, Styrene, plywood can be used to build the frame.

There are two ways to build this. With or without a controller. This Instructable will cover building with a controller. But there will be notes on what to do if you want an always on version, if you are using all Auto-Fade LEDs then a controller will not need to be used.

Step 1: Supplies and Parts


This Instructable has been updated with better information and better construction, please view the 10" x 10" LED Infinity Mirror Instructable

Everything is Included in the Full 8"x8" Infinity Mirror Kit (Discontinued in Favor of the 10" x 10" Kit)

Materials Needed:
- 1x 8.5"x8.5" 1/8" Glass or Acrylic Mirror
- 1x 8.5"X8.5" Two-Way Mirror, kit includes 1/4" thick MirrorPane( brand name) *Careful the silvered side is easily scratched.
- 4x Side Pieces*, measuring 11.9" x 2.25" 
- 4x Inner Walls*, 8.6" x 2"  
- 4x Mitered Front Pieces*, 12" x 2", 45deg miters
- Pieces to hold the mirrors
- Glue**
- 32x 5mm LEDs, diffused or water clear. Try Auto-Change LEDs
- 8 Channel LED Controller
- Stranded wire ~22ga. 8+ ft.
- Solid Strand wire, 22ga, 1 ft.
- 5v DC Power Supply with Matching Barrel Jack
- Krylon Fusion - Black or chosen color

Tools:
-
Soldering Pencil
- Tools for PCB building. (diagnol cutters, wire stripper, ect.)
- Hot Glue
- Small flat-point screw driver
- 5/16" Drill Bit*** and power drill

* The frame pieces included in the kit are Opaque 100mil Polystyrene. Acrylic could be substituted, it is harder to work with, but if you can make clean cuts its possible. Hard-Board ( Masonite ) could also be used, won't look as nice finished though. The same measurements can be used if the material is 100mil ( 0.1" ) otherwise adjust. Ex: 125mil acrylic, change the side piece from 11.9" to 11.875" & inner wall 8.6" 8.7" (they can be over length)

** Glue:
- The kit is supplied with a special glue for Polystyrene.
- Acrylic can use Methylene Chloride (Acrylic Cement, availible at hobby/crafts store) with chips of acrylic dissolved in it. Start with few chips and keep adding till its thick as corn syrup.
- Hard-Board, use a quality wood glue.

***Drill Bits
- Ask for the power and button holes to be drilled for you when purchasing your kit. Free of charge

Step 2: Frame - Front

 
Starting with two of the front pieces. Look over all the images first.

- On one edge apply a very thin even coat of glue.
To much will ooze out the joint and make the seems look messy later.

- Place both pieces flat on the table.

- Hang both edges off a table or platform so if it does ooze it will be easier to fix.

- Carefully press the to edges together and very slightly slide them back and forth a few times. Pressing in firmly. If there is to much gap between them you can either pull them apart and add more glue, or wait till its dry and a best side has been chosen, and apply more glue to the back of the joint.

- Line up the corners, the  Inner Corner is the most important to get the closest.

- If it oozed, wait till its completely dry and carefully remove with a razor blade or exacto knife.

- keep flat and don't handle it till its dry.  Stressing the seem will cause weakness.

Repeat with the second pair of front pieces.

Then, when you have your 2 halves, repeat the process on a corner and then wait till it has hardened  ( a few hours at least ). Then glue the final corner joint. It may need to be force a little to become square, just position it and tape it in place till it dries.

You'll be left with a nice 12" x 12" square with a 8" x 8" inner square.

Take a look at both sides seems and pick the one you think is best, as it will be facing outward.

Re-glue any seems your not sure about from the back. Just run a bead of glue along it.

Final step for the front of the frame is to give it a coat of paint.

I have found Krylon Fusion is best for Polystyrene,( better than Rustoleum for plastic )
I would suggest Krylon Fusion for acrylic as well.
And Hardboard can be painted with most anything.

Black is the usual, but any color will do.

Place on a flat surface with the best side facing up. You don't want paint on the back side.
Clean off the surface with Isopropyl Alcohol or some other weak solvent. To strong and it will melt the plastic.


Do quick even sprays, don't try to apply to much paint at once. Apply a few to several even layers, letting dry inbetween. Ensure to get the outside and inner edges.

Step 3: Inner Wall


If you have purchased the kit you can skip this step as the inner walls come ready for LEDs and installation.

Drilling for the LEDs:

- Stack up your inner walls(all 4 of them, they are 2"x8.6"), align them evenly and wrap some painters or masking tape around them on each end. To hold them square.

* Acrylic may need to be drilled 1 at a time, use a scrap piece to find out how easy it is for you ti drill

- Print the hole template supplied in the ZIP. Align and tape it to the stack of inner walls.

- With a 1/4" drill bit drill on each of the intersections.

Now for the blocks to hold the mirrors in place.

- Find some scrap material and cut some 1/4" x 1/2" pieces. Size really doesn't matter but smaller is better to avoid noticing them to much when the Infinity mirror is on. One edge should be perfectly straight.

- Take one drilled inner wall and using your mirrors as a guide glue the blocks on like in the image below. Place a mirror on a flat surface and stand the wall up next to it to use a guide for the placement. Remember both the 2-way and normal mirror might not be the same size.

- Check to make sure their placement is correct.

- Repeat with all the inner wall pieces.

Painting:
If need be, these could be colored with a black enamel  marker( big sharpie ), but painting is easiest. But they should be matte black.

* I use Krylon Fusion Glossy as a base coat(because it adheres well), then use some regular matte black to paint over that and it sticks fine.

The edge that will hold the 2-way mirror in, needs to be kept from getting paint on it or the glue won't hold.

- With some painters or masking tape. Tape down the edges of one side of the inner walls.

- With a razor blade cut off the extra tape so only the edge is covered.

Now that the front edge is masked off.

- Paint these the same way as the front of the frame. But they must be painted black, matte finish will produce better results.

- Remove the tape from the edge. It should be completely clean, if not, scrap off paint with a razor.



Step 4: Inner Walls, LEDs


Ready your hot glue gun.

- Be Careful not to scratch the paint or the LEDs while working.

- Insert an LED from the painted side through the first hole.

- From the back apply a drop of hot glue in the hole and spin the LED around 1 rotation to evenly  apply the glue. Align the LED's flat side towards the front mirror's side. Also, the shortest lead on the LED is the negative lead.

- Continue till all 8 are glued in and all the LED's flat sides (negative) are facing the same direction.

- If you are using multiple colors and are making a pattern ( example: in the images the mirror I am building is Grn-Blu-Grn-Blu-Grn-Blu ect) Ensure that when you place the LEDs when the walls are put up the pattern will be continue. if one wall starts with Blue it will end with green and the next one starts with blue and ends with green and so on.

- Repeat for all 4 inner walls

Soldering:

-All of the LEDs Anode's(long leads) are connected in parallel.

- With a needle nose pliers, grab both the LED leads at the base and fold the Anode ( longest lead) over. If it reaches the next LEDs anode,  repeat the bending on that LED and solder. Continue the rest like that.

- If the lead is not long enough to reach the next LEDs anode.  Fold a pair of LEDs anodes towards each other, then use some solid strand jumper wire to bridge between the pairs. ( The images below show this as my green LEDs have shorter than normal leads. )

- Repeat till all 4 inner walls have their 8 LED's anodes connected in parallel. ( all hooked together) And the cathodes are not connected to anything.


Step 5: Wire All the LEDs


If you are making an Infinity Mirror with no controller.
- If you are using auto-change LEDs, each LED will need their own resistor. Cut down the resistor leads and solder one of the resistor leads to a LED's anode and the other lead of the resistor to V+, or the LED's resistor next to it. Then the LED's cathode(short lead) is connected to a LED's cathode next to it. Repeat with all the LEDs

- If you are using a single resistor or Constant current source, connect all the LEDs cathode's together, just like the anodes. All the LEDs must be the same color or have the same Vdrop. Multiple current supply's could be used for different LEDs current needs. Not recommended.

Good source for calculations is ledz.com/

Wiring an Infinity Mirror with a LED Chase Driver.Purchase a Driver Here

Take a good look at all the photos before starting and things will make more sense.
Remember to be careful not to scratch or scuff the LEDs or paint job while working.

First thing is every LED cathode (short/negative lead) needs to have a wire run to where the controller will be. Leave a good 2 - 3" off the edge.

- Starting looking at the first image below shows how to cut dual-strand wire offset so each dual-strand can be run to two LEDs with less waste.

- Take a dual-strand piece of wire and estimate where to cut the wire, like in the image, so you can reach two LED cathodes and have  2-3" of slack to work with when attaching the wires to the controller.

- Clip the LED's leads shorter.

- Strip and solder the wires. Each to an LED's cathode. see images.

- Repeat with all 8 LEDs on that wall.

Next take your next inner wall, with all the LEDs and cathode(V+) supply ready.

- Place your inner wall with wires next to your next one. leave a 1/2" space in between. See Image.

- With a piece of solid strand wire, solder it between the 2 inner walls Anode rail.

Now the confusing part. Wiring the second wall to the first.
Again look at the images.

- It might help to write the number's onto the backside of the wall to ease in the wiring.

- Simply enough, each LEDs cathode should be connected to the other LED of the same number's cathode. See Diagram. Use the offset cut wire method, like before, to make your connections.

Now you have one half done and wired. Repeat with the remaining 2 inner walls

- Take a 4" piece of 22 gauge or larger wire and solder it to the LED anode's rail, and do the same with the second half of the inner walls. Both of those wires will connect to the LED+ spot on the controller board or to your current source V+.

Now would be a good time to strip an 1/8" off all the ends, so they will fit into the screw-down terminals.



Step 6: Attach Inner Walls


Now that the inner walls are ready to go up. Time start assembly.

First, the front of the frame needs to be masked off. This will help protect it from scratches during assembly and make it easier to paint the outer walls once they are glued on.

Use some painters or masking tape and some scrap paper to cover the front.
Then trim the edges down with a razor knife. Anything hanging over the outer edge will block the paint and leave a mark.

Next get the 2-way mirror out.

- Now would be a good time to clean the mirror with Windex or similar.

- Place the front-frame face down(masked side down)

- Center the 2-way Mirror in the opening with the shiniest side facing upward, should be about 1/4" overlay all the way around. Use the miter seems to help center it. If its not perfect just meet the difference half-way. Ensure the shiniest side is facing up, and the dull side will be seen from the front.

- Apply a bead of glue, not a lot, but enough, to the clean edge of the inner wall and align one end of it with an edge of the mirror. It should be longer than the mirror. Press firmly and slide it back and forth a little bit to increase adhesion.

- Use some tape to keep the walls close up against the mirror and pressed against the front frame.

- Repeat with the remaining 3 inner walls.

- Once you have all 4 inner walls up, Allow to dry and use some Foil Tape or other permanent tape to secure the corners together.

Allow to dry really well before handling or moving to much. The 2-way mirror is pretty heavy and it might break wet glue.

Step 7: Outer Walls


Outer walls are simple enough.
Place your frame with attached inner walls face down.

- Apply a thin bead of glue down one of the long sides of an outer wall.

- Carefully align it the long way against the edge of the frame.

- Slide it down, so that its edge is flush with one edge of the front-frame.

- The outer wall should be slightly shorter than the front-frame.

Check how your next outer wall should go up and apply glue to the edge and to the edge that will butt up against the first outer wall.

Finish the rest,

- Wait for glue to dry completely.

Paint It:

- Lay it on a flat surface so the paint cannot get inside, and using quick even coats, spray paint it your color of choice.

- Don't get any paint on the inside or on the wires.

The purchased kit can have its holes drilled by request. No extra cost.
I usually drill my holes in the corner. Apply some painters tape to mark on. Estimated 3/4" in from the end.

-  Drill with a 5/16" drill bit for DC jack

Two Button options are included:

For the Board-Mount Push Button: (preferred)
- Drill out 5/16" hole and then use a razor blade to make it a little bit bigger(square shaped) to fit in the button later. This button will sit flush on the outside.

For The Panel Mount Button:
- The panel mount button requires a 1/4" hole.

Touch up the holes with more paint or a black sharpie.

Step 8: Make Connections and Wire Up the Controller


 If a controller board is not being used.
- And Auto-Change LEDs are being used connect the Power Supples V+ to LED's Anodes and V- to the LED's Cathodes (each LED has its own resistor).

- Single Current Regulator such as a large wattage resistor, connect LED+ to V+ with a large wattage(3w+) resistor, connect all the LED Cathodes to GND/V-

This step requires the 8 Channel LED Driver to be assembled.

Take a look at the wiring diagram and start finding which wires go where. You may want to label them if need be.

The screw-down terminal's are extremely small. I had to use a flat head screw driver from an eyeglass repair kit.

All LED#1's go to Terminal 1 on the PCB
All LED#2 go to Terminal 2 on the PCB
And so on.

Screw them in tight and watch out for loose strands of wire that could cause a short.

There are 2 wires that are labled LED+ on the driver, each side should have one of those wires soldered to its V+ rail(LED Anodes)

- Mount the panel-mount DC Jack into the 9/16" hole drilled into the outer wall.

- Take the button mounted to the perf-board and with some glue (super, hot, epoxy) apply a drop to the perf-board and place into the prepared hole. Glue it in good.

Step 9: Finish Up


- Carefully place in the 1/8th regular mirror face down from the back, and it should fit perfectly above the 2-way.

- Tape it in with Aluminum Tape(supplied in the kit) or another tape that doesn't curl or stretch (electrical/duct won't work to well)

- Flip the the frame over and remove the masking.

- Finally time to connect the PSU to the DC Jack. It should turn on.

- Test the button make sure it works correctly to change the pattern.

- Once tested, hot glue the driver PCB to the wall.

- With the kit are a few different colors of vinyl dots to be put over the button. Choose one and apply to the center of the button. I am using black

*If the tunnel effect is curving to one direction. You'll have adjust the rear-mirror (regular), just remove it from the frame and raise the side that it is turning towards with some tape, layer it till its the tunnel effect goes straight back correctly.

Step 10: Optional: Hanging Bracket


Included with the kit is a plastic piece that is for hanging the Infinity Mirror on a wall. It is made to hang the mirror at a 45deg, diamond shaped. Should fit most hook-style wall hangers.

Before doing this part the mirror needs to be completely finished, tested and adjusted (if the mirror needs it)

Choose which corner to hang it from, usually the cord and button are on the bottom corner. This bracket will glue to the outer walls and to the inner walls.

- Test fit the bracket. And remove any tape that will be under it.

- Scratch off any paint from the edge with a razor blade.

- Apply a bead of glue to the edge of the inner walls where the piece will fit on top of.

- Apply a bead of glue to the mitered edges of the bracket.

- While trying not to drag or move the piece around to much, put it into place.

- Keep pressing it and gently wiggling it to fuse the bracket to the rest of the mirror.

Once its dry, ensure that it is sturdy before hanging it up.





Where do you get your two way mirrors? I made one a while ago and used a window film, but didn't work well. It didn't have much depth, only about 5-6 levels deep.
<p>I have only been able to find it in 1/4&quot; under the brand name MirrorPane in the USA, every glass shop I asked carry it. Used to keep the sun out of commercial buildings.</p>
<p>very nice</p>
How thick would you say that the entire mirror assembly is? <br>(Mirror assembly meaning all of the components that make up the actual infinity mirror. This is disregarding the table construction that supports it from below) <br> <br>I saw that the &quot;inner wall&quot; in the diagrams above are 2 inches thick. Does all the LEDs and mirrors fit within that 2&quot; assembly space? Or can it vary depending on how you build the spacing between the mirrors?
Please read the updated version of this Instructable at https://www.instructables.com/id/10-x-10-LED-Infinity-Mirror/ <br>That mirror kit is overall 13.5&quot; square x 2.25&quot;(the outer walls are 2.125&quot; + 0.125&quot; thickness of the front frame) If you wanted a thinner mirror you can adjust the width of the inner and outer walls. But the depth of the mirror effects the spacing of the infinity effect, a deeper mirror makes the effect go back further and in further towards the center.
I was thinking about making one of these, but don't want color changing lights or anything fancy like that. I just want them to be one color. Could I just buy a strip of lights like this http://www.oznium.com/led-strip-flat-head or this http://www.oznium.com/led-ribbon instead of the way that you did it? I wanted a cheap, simple method to make one of these and was thinking this would work well.
It is important that the LEDs used must extend out between the two mirrors and must be diffused. 5mm diffused LEDs work perfect, so maybe you can find something that will work the same or you could get creative and glue a bead or some diffusing medium to each of the LEDs on a SMD LED strip.
What is the best viewing angle for the LED's?
The LEDs should be the diffused type, clear ones don't work as well.
where else may i find the materials for this same project.
thank you
Would it work if I used a 1/8&quot; thick Two-Way Mirror instead?
Of course, would need to change some of the measurements for the blocks on the inner walls though.
It's good to use some hot glue on the wires coming directly from the PCB before handling much, they really like to break off.
I believe you got a little confused my friend. the negative ends should be connected in parallel and the positives should have all a wire connected to them from the controller. the way you said to connect the system would not work.
It may seem like that somewhere, writing this step was kinda confusing for me. So I would say go more by the pictures than the text. But I know for sure that the controller board sinks current so the LEDs cathode's go to the screwdown terminals and all the LED Andoes are connected in parallel.
great work!<br><br>https://www.instructables.com/id/cool-DIY-infinite-LED-tunnel/?&amp;sort=NEWEST&amp;limit=40
Hi, Love the tutorial, im wondering how much space is between the two mirrors and the LED's in the middle? Im assuming it goes 1 mirror on the bottom - space - LED's - space - two way mirror, but how much space is given between? cheers
Yes thats correct theres about a ~2&quot; space between the mirrors, and the LEDs are centered between them.
Looks great. The link to your ChromationSystems-InfinityMirror.zip file seems to be broken.
I hadn't noticed that, thank you. All the of the plans are in that file. I will fix it tonight.
This looks amazing, i think i'll get a kit!
how much is a kit
One the links to my store was misdirecting, I have fixed it.<br> <a href="http://www.chromationsystems.com/store/index.php?main_page=product_info&cPath=68&products_id=239" rel="nofollow"><br> Visit The Store</a>&nbsp;for pricing and info.
