LED Cube Night Light

Featured
Picture of LED Cube Night Light
This LED lamp will be perfect in any home. It gives more light then I thought it would.

Today I recieved the last products I ordered to get started building this LED cube.

Though this cube I made is 9cm x 9cm x 9cm... it feels bigger then that. Maybe because it gives allot of light.

In most of my projects and instructables I use a toggle switch to switch LED's on and off. I wanted to do something different this time. Got to say it worked out pretty awesome.

On the bottom is small momentary switch that will turn the LED's on and off. The switch is strong enough to hold the cube. But when the box is pressed down, the switch isn't strong enough to click back because of the weight.
So pressing the box will turn the light on, and pulling the box up will turn it off again.

Below you can see a movie I made to show how it works.
If you think it's cool enough, go to step one so you can get all the materials and tools to build your own!

Step 1: Tools & Materials

Picture of Tools & Materials
The materials used for this project are pretty easy to get and not too expensive.
Only some tools are maybe not in everyone's toolbox. But there are also many tools you can use instead if you're not able to get your hands on some.

Materials
- A4 acrylic sheet - 3mm thick (also known as 'plexiglass') - $2.00
- Fine sandpaper (400 does a great job!) - $1.00
- 3x 5mm LED (I used blue, gives a good effect. But any color can be used) - $0.21
- 2x button cell battery (CR2032) - $0.30
- 2x button cell holder - $0.50
- Small momentary switch - $0.25
- Electrical wire - $0.00 (ripped it of my bike)

As you can see this is a low cost project. The total money I spend was: $ 4.26
Most stuff you can get real cheap of eBay.

Tools
- Jig Saw (also a Jeweler Saw can be used. But that's really hard to get straight lines)
- Glue Gun (hot glue)
- Drilling tool
- Pen

Ones you've got this stuff you're ready to begin!

I'm new to all this so can someone send me a tutorial or explain to me how I would go about being able to control the colors that show up on the cube please if i put a RGB LED in there?
Malharhak theorio5 months ago

RGB leds have three inputs for the colors (and one for 5V). So if you wanted to put RGB leds and control them in it, you'd need three potentiometers linked to each of the three inputs, so that you can control red, green, blue.

Or, you can use an arduino and code a program that controls the light (like I did). But then it's another story

Malharhak made it!5 months ago

I made it, for now controlled by an Arduino using RGB leds, so it interpolates nicely between colors.

Although I'm wondering, did anyone find a way to be able to replace the batterie ?

This probably seems like forever ago but what does having the resistor in front of each led do? If one burns out it'll still work? Also, how did you get the attach bottom panel to the whole cube? thanks
I replaced the batteries with a proper ac connection.It worked

Excellent !!, I think this will be the one I try first.
next step, would be to power it via usb (optional) and make it programmable with an arduino or something, make it light up to music!

anyway, Nice build!

I like that it's moveable, I can put it anywhere in any room I want. With a USB connection I can't... though in the end it would save me batteries :)
I've seen allot arduino stuff, but it seems complicated. Maybe my next step is to focus on that and see what is possible for me to do.

Thanks for your comments!
One other thing!
i have the schematics to make it pulse to music, either via audio jack input or mic.
Just e-mail if you want it...

estimado sr. rickythemaniac
me interesa tu proyecto pero no entiendo mucho de esto, y me gustaria que tuvieras la amabilidad de compartir tu esquema para poder terminar el que empece, tengo mucho tiempo disponible para hacer este tipo de cosas novedosas y bonitas pero el desconocimiento me hace buscar informacion afortunadamente di con esta gran pagina. y aca estoy, esperando ojala una buena respuesta.
desde ya gracias por tu tiempo y atencion

i saw that exact circuit in another instructable and made two LED light bars that pulsate to music. it actually works very very good when used with an ipod dock!!
glad to help^^
 can you explain that better, I'm not the best with electronic schematics and don't really understand what everything in there is
*Cough* Ahem. XBee is your friend!
I've only been playing with the arduino platform for a few days, and it's sooooo simple. I have NO background in computing, other than common sense. The free download of the software comes with pre-written 'sketches' that are easily modified. I'll have to do one of these 'instructables' for the Aquarium Dragon I just modded. Dremel'ed out his eyes, replaced them with green LED's, added the Arduino, and now they fade in and out... and he's still able to be put in the Aquarium!  (ARDUINO ROCKS!!!)

i like this a lot. when i was looking this up i was also playing battlefield 3 and on one of the maps i saw this image i uploaded. no joke i looked at your cube then at my tv screen lol.



just have a few questions for anyone that has recreated this, have you

A) found a way to put the box together and not make the glue show

B) hide the electronic part.

What software did you use to draw out the circuit?
Try out this open-source circuit prototyping software which has a lot of predrawn parts you can simply drag and drop: fritzing.org

It has 3 modes breadboard, schematic, PCB. I find breadboard view is much more user friendly.
Thanks!

hay sorry but, what type of leds did you use ?? and what type of battery you use? thanks, and i hope you can answer.
battery is cr2032 the LEDs are 5mm waterclear LEDs but he diffused them

Wow i could only find switches for 2 bucks at the cheapest.....im curious where to find cheap switches....does anyone know?

Also if you dont want to spend alot of money on batteries just power it via USB cable
dr. zoid2 years ago
quick question, i have color changing 5mm leds, would they change colors or do i need a chip or circuit for that?
im new, please dont think of me as a fool! :P

Very brilliant, but, again, is there any way to mod the design so that the battery compartment is accessible without having to tear into the thing?
yaly ewitwins2 years ago
you could carve in the plexi glass two small compartments for the batteries and their holders and make sure they are flush
Instead of sanding down the last side to fit in the hole, could you keep it how it is and line the edges with velcro, so you can just take it off. Never used velcro and plastic before, but the concept makes sense.
motadacruz (author)  ewitwins4 years ago
The batteries need to be inside.
But you can make the bottom part fit tight but easy to open. If you make a hole in the bottom where you can put your finger in, you can open the bottom in a second (just with yout finger). Put the new batteries in and close it again. This would take less then a minute to change batteries.
Cool! Simple but elegant, thanks!

I wish you had more step by step instructions for this part with pics...  you've been very good up until now. I need more instructions with all the circuits and stuff. Which for me, is the tough part!
motadacruz (author)  dragonflii4 years ago

It's actually a really easy circuit. To understand it easier I made a image for you with the circuit (see step 6). As you can see it's not that hard. Hope it helps you understand better.

How often will i have to change the batteries?
Nice way of showing how to make a circuit, it's clean but you can see exactly how things must be wired! I still get confused with led's and diodes in the standard wiring prints where they are triangles :P
thank you! i'm not super savvy on circuits... but pictures help! ^.^

What type of leds did you use? or do they just have to be 5mm, without any regard of how powerful they are?
tirth53 years ago
how do you get the lights to stay on without holding down the switch?
Jimmacle tirth53 years ago
The switch is a toggle switch. Push-on then push-off.

Would square LEDs work?
Jimmacle tirth53 years ago
The shape doesn't matter, as long as the specs are the same.
Renmanace3 years ago
did you used some software for that circuit , its really fancy :D
