In this video, we are building compact and easy to make headphone stand with subtle lighting.
Hello and welcome to DIY Perspective.
Today we will be making simple and compact headphone stand with inexpensive materials
and basic tools.
I needed a headphone stand and I needed quite compact one.
But the more compact and small stand is, the more unstable it is.
So I thought, why not combine concrete and plywood then?
Concrete base will give good stability in small size factor and with plywood you can
achieve interesting design by gluing cut pieces together.
As I never worked with concrete before it will be nice to try something new, so let's
dive into the building process.
First, we need to mix up concrete with right amount of water.
Usually on a concrete package is written how much water you need to add.
Do not forget to wear protective gloves.
Then, we need to add some cooking oil on a paper towel and then rub inside the mold that
concrete wouldn't stick to it.
For the mold, I used 10.5 centimeters diameter small bucket in which were ice cream.
Now we can put mixed concrete in the bucket.
You should keep adding concrete until it reaches 3.5 centimeters of height.
Don't forget to shake and vibrate concrete that most of the air bubbles would escape.
I did it for about 2 minutes, but I suggest doing that for at least 5 minutes, until all
smaller bubbles comes out.
Finally, cover concrete base with something like a plastic bag and let it cure for 3 to
5 days.
While concrete cures, let's move to cutting parts from the 6 milimeter plywood.
We need to cut 5 parts in total.
The middle part that you see on the template, we need to cut it 3 pieces of that.
Three parts will make the front face and other two will make back of the headphone stand
where we glue LED strips.
I'll leave template in description below, if you want to make exact same size headphone
stand.
Clamp plywood with guide board for the straight cut.
I suggest using smaller blade with more tooth for the jigsaw, this will give clean cut without
chipping plywood corners and it will make it easier to cut the round parts.
For those parts I just did rough round cuts and then sand it down.
I used 100 grit sandpaper for forming round corners and then sanded all parts with 100
grit and 220 grit sandpapers to get smooth surface.
Headphones should hang on something, so for that I used round 1.5 centimeter diameter
decorative wood stick and cut 2.5 centimeters of it.
You can cut it longer, depending on your headphones.
Now, when we have all parts nice and smooth it's time to glue parts that will be facing
front.
Add glue and spread it.
Normally you should spread glue all around parts but in this case do not add glue around
the edges.
This will prevent glue from squirting between parts when you clam them, and you won't
need to sand glue from the plywood later.
One exception is the bottom edge, there you need to add glue all the way to the edge,
because there we will be drilling hole for the screw, which will be holding wooden headphone
stand part with the concrete base.
While glue is drying, we can cut plywood parts for the dimmer.
I used a fretsaw, it's quite easy to cut small parts with it.
Then sand all the cut part edges with 100 grit sandpaper and later, when we glue these
parts to get small box, sand it with 100 and 220 grit sandpapers.
Add glue, assemble the box and press with something heavier.
Leave all the glued parts to completely dry out.
Next step is to make holes for the wires from the LED strip to the dimmer.
On the bottom back part we need to cut some plywood, that we could route wires to the
dimmer.
On the top part, we need to drill two holes to continue path to the dimmer.
I connected two holes just by wiggling a drill.
Then add glue, clamp parts and let it dry.
We need to drill one hole for the dimmer and one for the power cable.
When glue on the back part dried up we can glue it to the front face of the headphone
stand, clamp it and let it dry.
Next, is time to apply some sort of finish to the plywood.
I clamped two wood pieces and hot glued the headphone stand parts to them.
Hot glue is quite nice temporary holding solution for the wood.
I used redwood color finish and applied 4 coats.
As plywood doesn't have that nice texture as regular wood, 4 coats will give that rich
redwood color.
As I already applied finish to the plywood, I realized that I forgot to glue the small
round stick, which I cut before.
So I just waited until plywood finish completely dry up, lightly sanded the spot where small
decorative stick will be placed, glued it and clamped it.
Now we need to take the concrete base and drill the hole for the long screw, which will
be holding the plywood part.
I drilled 1 centimeter from the center of the concrete base.
In my case, the 6 centimeter screw sticks out by 3 centimeters.
As my concrete base bottom part wasn't as smooth as top part, I first sanded it with
60 grit and then 220 grit sandpapers.
Sandpapers clog up very quickly so it's good idea to vacuum all the dust from sandpaper.
In the next step, we need to drill straight pilot hole into the plywood stand.
I used guide board and placed my drill that it would drill in the middle of the widest
part of the stand.
When plywood finish completely dried up, I slowly and carefully drilled few millimeters
of plywood from the box that the dimmer would fit perfectly as I drilled the hole for the
dimmer few millimeter off.
Now, let's start connecting RGB LED strip to the dimmer.
First, cut protective material near the contacts from the 40 centimeters length RGB LED strip.
Route two wires through the previously made hole.
And solder them to the RGB LED strip.
Route power cable through the hole.
I used 1.5 meter of a thin and flexible cable, which later be connected to 12V power supply.
Then place the dimmer in the box, and solder power cable's positive and negative wires
to the dimmer, where DC IN is written.
Then, solder RGB LED strip's positive and negative connections to the dimmer, where
MOTOR is written.
Finally, solder power cable from the headphone stand to the 12V power connector.
Just don't forget to put this part first.
Add electrical tape around the wires near the contacts and screw on power connector's
protective shell.
Now we can test, if we connected everything properly.
And in my case, everything looks great.
If you wonder why not all LEDs light up, it's because I used RGBW strip.
That means that it has extra white LEDs.
But in build like this you don't need extra white LEDs.
I just didn't have regular RGB strip at that time, so I used RGBW strip instead.
Next, we need to hot glue the dimmer and 12V power cable to the box.
Then add electrical tape around RGB strip contacts.
This outside access of the LED strip connections, will let to change color by re-soldering to
other RGB strip contacts, if someday you want to do that.
Next, glue RGB strips around back of the plywood stand.
RGB strips consumes way less power and doesn't heat up as regular LED strips.
This means that you don't need to use any metal heatsink material for the cooling.
I run RGB strip for 1 hour at 12.5V and measured just around 15 degrees higher temperature
compared to when LEDs were not powered on.
Finally, glue the dimmer box to the main part of the stand.
I just used wood glue for that.
While glue are drying, we can spray concrete base with clear protective finish.
This will give wet and shiny look for the concrete.
When concrete finish dried up, we can finally screw plywood strand to the concrete base.
That one quite short screw holds two parts very well.
And finally we did it!
This build was really enjoyable to make, because I never worked with concrete before and I
always wanted to try it out.
I thought, it will be much harder, but actually, it was quite easy.
I would say that hardest part of this build was applying finish to the plywood parts.
Next time I would probably buy some spray finish, to easy up this process.
