LED Cube 4x4x4

Amazing 3 dimensional LED display.
64 LEDs makes up this 4 by 4 by 4 cube, controlled by an Arduino (Atmel Atmega328 microcontroller).

Knowledge list:

  • Basic electronics and soldering skills
  • Know how to program an AVR microcontroller – I will not cover that in this instructable.

Since the Arduino has a total of 20 pins (including the analog pins) we will not need to have any multiplexing or shift registers.  I will take you though what i did in order to build the cube and create some designs of your own.

Here is the full documentation of the project.

LED DIce Arduino Shield

FW8EJF0HFD0ZC6D.LARGE

Step-by-step instructions for Arduino based LED Dice. I had aruduino Duemilanove (the older version).
Here i made arduino shield for LED DICE.
What is a Shield?
Shields are boards that can be plugged on top of the Arduino PCB extending its capabilities. The different shields follow the same philosophy as the original toolkit: they are easy to mount, and cheap to produce. If you’d like to make your own shield, you may want to start with the Eagle files for an existing shield.

TV Remote Jammer

FOXSDXIHGIEVH5E.LARGEAs,we all know that the TV remote is the cause of fights among  us and our siblings(specially the younger ones).So, was my case . I decided to prank my family members by making the remote jammer. Original ible of kipkay is here.

How Does Remote Really Work ?

The concept is pretty simple and easy. You press a button. When you do that you complete a specific connection. The chip senses that connection and knows what button you pressed. It produces a morse-code-line signal specific to that button.

The transistors amplify the signal and send them to the infrared LED, which translates the signal into infrared light. The sensor in the TV can see the infrared light and “seeing” the signal reacts appropriately.

The frequency of this transmission is between 35kHz to 40kHz(38kHz in most of them).

What the jammer does is that it sends out a steady stream of binary code at the same frequency as of the remote.The TV cannot decode as it contains no information.

The information transmitted by the remote does not get pass through as the jammer is on and does not respond at all.
So, the remote is jammed and you can tune in on to one channel and give away the remote.

Here is my schematic and board file made on eagle.
