I'll start by saying that I recently sold this table and don't have access to it anymore. I've gotten a bunch of messages from people wanting to buy either another table or buy a guide on it. I decided to write up a guide with some of the knowledge from the previous table I built. That said, I don't have pictures for every single step nor do I have measurements. There is a lot of leeway with how much you're willing to pay for each piece of this design.

My table had a wireless charger built into the side of it. This didn't end up charging as fast I would like since it had to go through wood, albeit a very very very thin piece of it. I will include that part at the end, but its worth noting if you want that addition to check the end of the article before continuing to know what steps you'll need to take for other parts of this. I got a lot of inspiration for this guide from this youtube video, but had to change a lot as well to adjust some of the shortcomings I saw as well as to adjust for the wireless QI charger. I HIGHLY recommend watching it to get a better visual.

Step 1: Materials Needed

IKEA Lack Coffee Table - https://www.ikea.com/us/en/catalog/products/100659...

LED Lights - https://www.amazon.com/gp/product/B01DBINHWA/ref=o...

Mirror - Any regular mirror will work. You can go on craigslist and find one. I have the early dimensions written as 28" by 16". If you want a better dimension, I would recommend ordering the table first and then marking out exactly where you want the mirror placed. From here, you can also go to your local mirror cutting shop and get a piece cut to size. This is what I did.

Glass - This is the piece a lot of people will have their own customization on. I made a small infinity mirror two years ago and used acrylic glass with cheap tint. I do not recommend this. I recommend getting Silver 80% Tint. This is the same type of tinting used on police interrogation rooms. For this, I recommend going the more costly route and going to your local window tinting company and asking them to do it. It can usually be done for around $30. Otherwise, you'll have to look around for the roll of tint somewhere else. Note: You can choose a different tint. I did a lot of research into it and was finally able to find the Silver 80/20% to be the BEST you can do. If you have questions on this feel free to contact me.

Wood Nails

Double sided tape

TOOLS

Jigsaw

Step 2: Cutting the Table

Take your mirror and lay it on the table as center as you can get it, then mark the borders off with masking tape. Make a holes in the top of the table either by drilling or by other means. This will make it easier to pry out later.
Use the jigsaw to cut down the tape, making sure NOT to cut the bottom of the table at all. Adjust your jigsaws blade to account for this and if possible, have somebody there to make sure you're not cutting the bottom and to act as a duster for the wood dust coming off the blade.
Once you have the top cut, you can pry it off with almost no effort and begin taking out the inserts in the table. This is probably the most satisfying part of the project. Vaccuum up the remaining dust and move on to the next step.

Step 3: Making the Wood Border

Make a wooden border that is the length and width of your mirror. I have written down 1.5"x1". Luckily, this wooden border is the cheapest and easiest thing to configure in the project. Once you have your border made, make a hole the size of a nickel or so by one of the corners. I would watch the youtube video linked in the materials section to get a better understanding if you're confused by any of this wording. Be sure to make this as straight as possible.

Once your border is made and the hole is drilled, paint it black. This will help keep its profile low. Next comes actually putting the LED's onto the border. I'm going to make a numbered step list for this since the LED's are more tedious if it's your first time working with them.

First test the strip by plugging it in and making sure you know how it plugs in and the way it works. The way the one that I linked works, can be seen by viewing this diagram.
Start by putting down double sided tape along the inside of the border. The reasoning for this is that the sticky backing on the backs of LED strips are not as sticky as one might hope.
Take the LED strip from the beginning end feed it through the hole. You want at least an inch of the led strip to be going to the outside.
From here, unroll the strip and place it down. Taking off the paper on the back and trying to keep it as straight as possible along the inside border.
Once you reach the end, find the dotted line along the LED strip and cut there. The strips are marked off in sections and cutting it wrong will result in parts of your strip not lighting correctly or being completely turned off.
Test the strip by plugging it in.

Step 4: Placing the Components In

This is either the easiest step, or the most frustrating. Diagram on how it should look.

Place the mirror on the inside
Attempt to place the wooden border on top. You will probably need to push it down a bit to get it to actually stick.
Place the tinted glass mirror side DOWN. If it is raised out of the table, be thankful as this makes it easier to take it out. You're looking for a sweetspot of a few centimeters.
Make a hole in the bottom of your table in the same corner as the hole you made from before . This needs to be close enough to it that there isn't any strain on the strip.
Tape the LED sensor box next to the hole and plug in the strip.
Connect the power supply. An extension cord will probably be needed.

Congratulations! You just made an infinity mirror coffee table. The next step involves wireless charging and is optional. I hope you guys enjoyed this instructable. This was my first one so if anyone has tips on ways to improve this I would appreciate it. I apologize again for the lack of pictures, I never thought I would be making a guide for this. If you have any questions you can contact me on my email.

Step 5: OPTIONAL Wireless Charging

Wireless charger used - https://www.amazon.com/Anker-Qi-Certified-Compatib...

The big part you're looking for is FAST charger. This specific one listed also needs a separate power supply.

With the wireless charger step, you'll need to measure how far out the charger is and base a side of your mirror on that width. The charger sits under the wood next to the mirror. The charging capabilities do not go through the glass unfortunately.

Once you have done this, follow the guide up to the point of gutting the table. Next, take a chunk of insert out from one of the corner edges that you want your charger to sit in. Find a piece of wood that is big enough to push the charger up against the wood top and use that. This will be your post potentially annoying part so sand down some wood until you get that perfect height.

Continue following the guide until you reach the end where you are inserting everything. Have your wireless charger with block of wood sitting in the table first and plug it in, feeding it through the hole in the bottom of the table. This needs to go through the edges of the table so the wooden border won't get blocked. The wire does not go through the hole on the wooden border. Finish up by putting the other components into the table and test.
