Music Visualiser Table

This Instructable will hopefully give you all you need to put together a reactive music led table.

I based it on the Music Visualiser at Music Visualiser - Adafruit. The code is from there, the circuit is from there - all I really created was a big led matrix, and put it into an Ikea table!

Really, I wanted to make a full arduino tetris table, but I had most of the spare parts and wood available to make this, so that's what I did.

As a picture is worth a thousand words, there are lots of pictures as I hate writing!

Step 1: Modify the Table

Start with an Ikea Lack table - the matt white was on special at f5, so that's what I used.

Draw a square on the table - mine was 40cm * 40cm - giving me 5cm2 sections.

Not knowing what the table was made of, I cut a small hole to look inside.

Happy with what I found, I cut the square, and removed the honeycomb cardboard inside.

Step 2: Realise your mistakes

Having cut the hole, I sectioned off the white square I'd just cut out.

I then glued the triangle I'd cut back in place. Oops.

Then section off the board into 5cm2 pieces.

I made template for the led holes- yes it's an old rail ticket, and marked the holes.

Drill loads of holes and fill with leds.

Take a picture with all the leds in place. Feel good about what you've done.

Step 3: Making the matrix grid

I got some white laminated hardboard I found in the garage and cut strips. The height was based on the depth of the table. There weren't measurements - it was done by eye.

I then used the bandsaw to cut the intersection holes. I then used the kids 'gloopy glue' (pva!), to stick reflective photopaper to the other side of the hardboard. I used a craft knife to cut this to size once dry.

I assembled the pieces and glue-gunned them into place.

Step 4: Creating the led matrix

This is making a very large version of the common cathode matrix found in the attached datasheet.

There's a lot of soldering and about 20ft of wiring.

Step 5: Connecting the circuitry

Connect up the circuit as described in the attached pdf.

I'm sure I could have done it a hell of a lot neater, but it'll be hidden in the table, so it doesn't really matter.

Test the matrix and circuit as in the video.

Get a piece of perspex the same size as the matrix, and cover it in frosted window film. If you can find pre frosted perspex then this may save you some effort. For added diffusion, I used some greaseproof paper as well.

I cut a hole in the bottom of the table to allow a usb cable to fit through.

Slide the matrix into place.

Glue to plastic top in place.

Your table is now complete.
