Sound-Responsive LED Painting (on the relatively cheap)

Picture of Sound-Responsive LED Painting (on the relatively cheap)
This instructable will show you how to make a triptych painting with LED lights that respond to music. I will be honest and say that this isn't the first project like this, but this is how I made this one and it's relatively cheaper than other projects I've seen like this, which ended up with an overall cost of $2000+ or something. This project cost me maybe $60 total, if that, although I did have some of the required items already on hand and the two major components were on sale on Amazon at the time of my purchase.

I didn't take pictures as I went, so I apologize that all the photos were created in MS Paint.

Here's my final end result:

Step 1: Gather Your Materials

Materials Needed:
-Muslin (fairly thin or see through for the lights)
-Square wooden dowel rods, ¾ in, straight (make sure they are not too warped or bent). Use a lightweight wood but not a “fake” wood which would split. I got mine at Home Depot
-freezer paper (for the stencil)
-acrylic paint
-iron
-paint brushes
-wood glue
-staple gun (optional)
-hot glue/hot glue gun
-This LED light set
-This IR controller (This company has other IR controllers but they may not have three ports. I’m sure there are other IR controllers that work the same way; just make sure that there’s a correct number of ports for the number of panels you are making. This is the one I used)
- extra connectors
-printer/paper
-tape
-solder and soldering gun

Step 2: Make the Frames

Cut the dowel rods into pieces, four 2 ft. pieces, four ½ ft. pieces, and two 1 ft. pieces. Make three frames with wood glue – two ½ by 2 and one 1 by 2. Make sure the glue is completely dry before moving on. You can reinforce the frame with staples if you want, but the wood may split depending on what type of wood it is. I didn’t use staples.
