The One Chip LED Cube

Hello Fellow Instructables,
If you ever Wanted to make Your own Cube, But Found The Instructions To be a bit Hard To Follow?

Well  This is For You.

The Cube Comes as a Kit From KIPKAY Kits.  You Could Buy it, or Become a Member and Each Month You will get a New Kit.

It is Very  Easy To follow the Instructions And The Video.

Well Here its Mine, 4x4 L E D  Cube.
The Ship Comes Already Programmed With The Code . 
The  Hard part is Making All the Connections  ..As long As you Take your time And Double Check All You Will be Pleasantly Surprised.

For Details On this Build,, Please Check The web Site.      www.kipkaykits.com
Hope You Like it as Much as i did.  
My Second LED Cube its the Blue one...  Will be making a   8x8x8  Cube Next.



Hey   Hey Go and Make Something And Have fun.

You might get more traffic if you touted this as "The ONE chip LED Cube".

You're right, most people are daunted by the task of assembling a cube, and also sometimes the cost. This is a nice, neat, single chip cube that I am sure most people could construct.

If you ever want to build one of the 8X8X8's though, look me up and get a PC board from me. My biggest advantages are that everything is on one board for the controller, and if you choose the ATmega32 (it also takes the ATmega328P) then you can have it music triggered too without sacrificing the ability to run older code without modification.

thanks for that

and i will be getting one of your boards and controllers.

together. they look great.

hi there. the 1st

Item you must have is a Bread Board. its a Must PLEASE DO NOT Play With The Electricity From The Wall. Get a Power Adapter. My L E D Cube Uses 3.3V To Run. My Cube Came As a Kit From www.kipkaykits.com

Here You will find The Schematics For the Cube.

The Parts I Used For a 4X4 Cube

1 Atmega8 Microcontroller

75 LEDs 5mm Diffused

1 PCB 10X15 cm

1 Power Adapter 5v 1a

4 PNP Transistors

4 10k Ohm Resistors

4 100k Ohm Resistors

1 IC Socket 28 Pin.

Copper Wire, Red/Black Wire,

The Micro controller Comes Programmed With The Code So the Cube Changes

Patters .

Hope this Helps. And Please Careful Be Safe Around Electricity.

It is true a led is a diode but diodes have a characteristic known as piv, that's peak inverse voltage. This is the maximum voltage that the diode can stand in the wrong direction before it is bye bye diode. In the case of led's this can be as low as 20 volts or less. In the UK the mains is 230volts rms which means it actually peaks at 320 volts. Clearly led would be instantly killed. It would be possible to use a reverse ordinary diode with a current limiting resistor but that would dissipate a lot of power. Often a capacitive dropper can be used. The advantage of a transformer is that it isolates you from the main grid. Perhaps I should write an indestructible about using capacitive mains dropper's and transformers.

yes please do a

instructable we all could learn from you. cheers mate.

I have a quick 1 part solution in one of my instructables about how to power a project. Have a wander through my stuff, and while you're there, see if there's anything else you like.!

I have made my first instructable, I think it has published. Its titled how electronic components work. The diode.

Hi there! Awesome project. I am doing a similar project with LEDs.

I don't know much about electronics so please bear with me. Last week I went to the electronics market and some guy there told me to use a 47k ohm resistor in series with one LED and hook it up to a 220V AC supply (from the wall). I did that and it works!!! But unfortunately it works only for 3 LEDs max (in series).

Now I want to use the AC power supply to light up about 40 LEDs and I don't want to use a transformer (Not possible on my student budget :D :P). Can you give me a minimalist circuit diagram and if possible parts list to get this done.

Please can you tell me what values of resistors I am supposed to use so that I can light up all the 40 LEDs brightly.

Thank you for your instructable and thanks in advance for all replies

Amazed it worked as I would have thought the reverse voltage would have destroyed the led in an instant. My advise, don't do it.

I had the same doubt when the guy told me to put a 47k resistor in series and I also asked him if I should put any diode or anything else with it. He laughed at me saying LED itself is a diode (Like I didn't know that already).

anyway what do you suggest I do. To light up about 50 white 5mm LEDs via the power from wall.
