DIY Feature Wall

Make your own jaw dropping feature wall for your house using this simple instructable. Best part is you dont need much experience nor any major tools for this project(only angle grinder).
This project is not exactly cheap( average cost is around 18k) as the main item of this is a soundproof foam costing 10k.

If you like this project please vote for me in the LED strip contest. Each vote would be a great support from you guys for me to make more of such instructables.

Finally, I would like to thank my parents and my sister who helped me in this project. Without them I wouldnt have finished this project( in a month xD). So let's get started.

Here I've created a simple design using Paint3D which consists of circles and numbers. This design is made in such a way so that the gap between each circle goes on decreasing to show a fading effect towards the outside. If you see the picture, its 3 digit numbers where the 3 on both sides is the measurement(inch) for my reference. It can be anything but according to the foam size(12 inch), 3 would be perfect. The middle number depicts the measurement of the gap between each circle(6 inch) that goes on decreasing to show a fading effect towards the outside.
NOTE: Breaking down the 3 number sequence for "313":

3- Hexagon foam covers 3 inches on left
1- 1 inch gap between the two hexagons
3- Hexagon foam covers 3 inches on right

Since I couldn't find a large compass capable of making bigger circles, I had to make one myself. It's very simple. I have cut the pointed side into two and stuck it on either sides of a wooden stick(30cm) I got from Itsy Bitsy. I used fishing line to fasten the compass to the wood as shown. You can use any thread. Secure it in place by using fevikwik.
NOTE: Make sure both pieces are bend towards the same direction as done in the picture.

Here we're going to make a base for the hexagon foam so that it is projected outwards. This will give the hexagon foam a floating look. For this we'll be using the foam circles. Stick 4 pieces together perfectly one above the other using hot glue gun. For my design I needed around 71 of the base which is totally 284 circles. Dont mind the random colour combination, all these are not going to be seen after completion.

Here we're going to stick the embroidery rings on the foam so that it can be placed over the foam circles to give a floating feel. First we need to find the center of the hexagon foam. Join any two of the opposite corners, take the intersection as the midpoint and draw 6 inch circles from here using a compass. Once you have done this, place an embroidery ring around a base (circle foam piece) and tighten it. Remove the ring and you have your required measurement. Simply place the ring over the circle you just drew and stick it in place using hot glue gun. Refer to the pictures to get a better idea.

Dont get freaked out by the pictures. I had made a major blunder there. You guys dont need to do all this. What I planned was to put an LED strip for each circle. Later plans changed and only the middle was decided to be illuminated.
Here what I've basically done is created a groove on the wall which can incorporate a conduit pipe which houses the wiring for the LED strip. Refer to the picture where I've drawn a red line. That's the only groove you will be needing. It connects the led strip directly to the nearest switchboard. The red line varies for everyone as the nearest switchboard can be in any direction. So you can literally skip all the extra work(which I had to cover up as it was useless) and make a groove only where depicted in that picture.
We can then hammer a nail into the wall, and tie the pipe to it using a tie wire(metal bendable wire). On either end of the pipe, we need a 90° elbow pipe so that the wire can come out. This will be projected out of the wall's surface which we will later cut it in level with the surface of the wall. Use wall putty to level the surface.

The pictures will give you a good idea of what has to be done. As you can see in the pictures, the elbow pipe has been plastered around and cut in level with the wall to give a neat work. NOTE: Last 2 pictures attached are the current pic.

In this step, we're going to draw the same design on the wall. First you will be needing some guidelines. It's a good habit to draw guidelines before any sketch. So here all we need are 3 straight lines. Basically, you will be drawing lines that are 60° from the horizontal line at the center and extend on both sides. Hence we get 6 lines starting from a point and at 60° angles with each others. Take reference from the pictures.

For draw the circles, take the centers of two circles as your referrerence points. Refer to the 4th picture. Here you'll be needing the compass to cut intersecting arcs from the midpoints of two circles (the two circles that are closest to the new circle to be drawn and also towards the center). The lines with the same colour code is the ones you need to take for drawing the new circle. Every two new circles you draw becomes the reference point for the next circle. Dont understand this step, DM me on Instagram and I'll be happy to help you.

You'll also be needing a lot of snacks like mine and its better to have an extra pair of hands.

Here we're going to make a covering on the edges on both sides so that our circles and wiring cannot be seen from the sides. For this you need to cut the hexagon foam into 2 equal pieces. According to my design, we have to cut it along the diagonal(corner to corner, see pictures). This half is to be stuck on top of a full piece of
another foam using fevicol. The end result should look like the pictures I've attached.
So when this is attached on the sides, it doesnt expose what's inside. In all my projects, I make sure the work is neat and has professional look.

For sticking the foam circles to the wall, we're going to use 3M command strips. Place 2 strips on either sides as I've done in the picture and press for 30 seconds.

While sticking on the wall, peel the backing tape and press against the wall for a whole minute as you dont want these coming off. Secure it in place using hot glue gun around it.

OPTIONAL: Use a spirit level to check if the circles on the horizontal line are at the same level. This is the only row where the circles will be in a straight line. So this must be accurate as this will be the reference point for every other circle.

UPDATE: I've realised the strips and the hot glue gun were not sufficient for few circles and they came off. So to tackle this you can nail it to the wall using a small headless nail. Alternatively, you could use nails for all the circles instead of the strips as the strips dont come cheap. Last picture shows how it should turn out after painting the wall black.

I'm using Philip's LED strip and hence the driver is quite big. So you need to carefully carve out a small part out of the hexagon foam so that the driver does not disturb the hexagon. I used a knife to cut the depth on both sides and remaining part can be done by pulling bits of foam at a time. This step needs to be done carefully as you dont want to make a hole on the foam.

What you need to do is place the driver on the circle and mark the size which needs to be cut(refer pictures). You can cut it before sticking the circles on the wall or after, I've done after sticking. You'll need to cut both end of the driver carefully as it's slightly longer than the diameter of the circle(refer the pictures). Secure in place with fevikwik.

The circumference should be the length of your LED strip so that the light is spread evenly all around. You can make the length slightly longer if necessary but try not to make it short. Peel out the backing paper from the LED and stick to all around the BACK HALF of the diameter(touching the wall) so that it doesnt disturb when the ring is placed over the circle. Refer the pictures on how to stick the LED strip properly.

Tape the extra wire to the driver and run it inside the pipe. Pull out from the other end and connect it to the switchboard with a dedicated switch.

Final step
Place all the foam on the circles. The ring should fit perfectly around the circles. Some may be tight or loose, just switch it with another foam. After placing all the peices, it needs to be aligned so that a corner is pointed to the top. Take time and make sure all are aligned. You could also stick the ring but I preferred not to as its already quite tight and also would be easier to improvise in the future.

This was just one way and there are million other ways you can modify this according to your needs, different designs, colours and much more.
This wall completely changed the look of the wall and since I have made this a part of the Home Theater, it adds so much more character into it too.

Last image is where I have took apart all the peices(except middle) and it alone turned out to be really cool.

This is my first instructable so please excuse me if any step is not clear.

Thank you so much for watching and I hope you will also love making it as much as I did. Any questions, please ask me you can also DM me on insta @m3ss_w1th_m3 if you have any doubts or suggestions(I would love to improvise)
