How To Make an LED Cube

by Leave a Comment

This is a great build video for an 8x8x8 LED cube by Kevin Darrah that I stumbled upon on the web. It goes over the basic build techniques  and shows you how to utilize a jig for assembling the LED arrays. As you watch the video you will quickly begin to realize that this project is not for the entry-level builder, clearly this is something that will consume a lot of your time and patience but the end result is awesome. Either way, it’s interesting to see how it all comes together.Blue LED in a cube

There are many Arduino builds out there that can be great for beginners. If you’re not familiar with Arduino then I highly recommend that you read this introduction to Arduino, it covers everything you will need to get up-to-speed on what it’s all about.

You can find many projects in the Arduino Playground, they include schematics and code to help you build cool stuff. If you want to make a much more novice-friendly 3×3 LED Cube you can use these schematics and code.

So what are you waiting for? Find a project and get building!

ASCII stands for the American Standard Code for Information Interchange and it is a code that represents English characters as numbers in computers. There are a total 128 characters in standard ASCII and many of them can be used to create ASCII art, which is created by using the 95 printable characters out of the total 128.ASCIIHeart

You can easily piece together your own ASCII art by simply opening any text editing program but if you want a quick way to turn ordinary text strings into an ASCII art masterpiece, then check out this awesome Text to ASCII Art Generator by Patorjk.com.

Here’s an example of what one style of ASCII text art looks like. There are tons of different styles to choose from and there are even options to change format output.

You can also create images by using ASCII characters, you can use a picture to ASCII converter like Picascii. You can either enter a URL or upload an image to convert it to ASCII Art. There are even options for size and color plus an HTML formatter to ensure it looks correct when posting the art elsewhere.
