LED matrixes are used as scrolling lights to scroll news and advertisements, some are used to show iconic images like pacman and the likes. These have one thing in common – size they are relatively small. And now is the time upsize things, we don’t want an 8 x 8 array, nor a 16 x 16 we want a 64 x 32! Just enough to spice up the morning coffee.
Using an old IKEA couch, an arduino and lots and lots of bicolor LEDs Tobi gave life to his lonesome coffee time. The displayed are inter connected (4 data lines shared), which makes their latching action in sync – the first LED array is distinguished from the other LED arrays using the sync and CS control pins. This one of the best ways to spice up morning coffee by combining geeky electronics with hard core logic multiplexing.
You always thought that you can make different LED flashing patterns with several red LEDs, but you don’t know the exactly way to do it? Well, here is a solution for you.
You can see on the above figure, this tinyCylon is indeed really tiny, where its length even shorter than the LED’s total length! For your information, this tinyCylon kit is coming with five red LEDs, an Atmel ATtiny13 microcontroller and a 4.5V DC battery pack.
Do you believe that you can make the tinyCylon into a very, very tiny tinyCylon with a few modifications? Yep, you really can do it! First of all, you can choose the surface mount LED as the replacement for the kit’s T-1 LEDs, where any 0805 package SMD LED should work fine. And, all the red 3mm LEDs can be replaced with three color SMD LEDs as well!
Make sure to change the bulky and cumbersome 4.5V DC battery pack to a smaller yet portable battery supply. In this case, a 3V lithium battery is more than enough for the 3-AAA battery pack.
Remember to assemble all the components accordingly. Voila, now you get what you’ve dreaming for a very long time. Go and have some extreme fun with it!
You would like to buy the Christmas lights in the local store, but you just can’t buy it, as you want to save more money for the emergency use? Well, if you still want to decorate your house with the colorful and sparkling Christmas lights, then you might want to check out this following DIY Christmas Lights Controller.
The biggest advantage of using this DIY Christmas lights controlled with the .NET Micro Framework is it allows you to have the full access LEDs controlling. In this case, you can come up with numerous lights sparkling patterns than the ordinary Christmas lights controller that you buy at the store!
Furthermore, this project is also children-friendly, where it means that kids of all ages can have a go at building the hardware without messing around with mains. The lights that you’re about to use here is has to be as lines of twenty LEDs, where its all wired up as four strands of five LEDs each. All the LEDs in each strand are the same color.
The shift registers will play an important role for this project, where it will be used to control a ton of LEDs using a small number of controller pins!
By the way, remember to build this project with your loved ones…
Would you like to have fun with the RGB light bulbs? Did you know that with a DIY RGB light bulbs lamp, you could create a lot of fun moment, no matter where you are and what you did?
Honestly, most of the home hobbyists will start to involve themselves with the RGB light bulbs lamp because it’s a very simple and low cost project. As a result, this is the project that suitable to everyone, either for amateurs or experts!
The RGB light bulb lamp is fully remote controlled, where a large spectrum of colored light can be made by mixing light from bulbs colored in three colors: red, green and blue. As a result, this one is not based on LEDs but it’s based on 3x60W 220/110 Vac light bulbs, which it’s more interesting and sparkling than other.
Beside that, it also has a remote controller to change intensity of the three bulbs, store and recall the preferred hues, and turn the thing on and off accordingly.
Note: Since the three bulbs you’re using is 220/110 Vac, so you must be highly be careful about it, as it might causing some damage, injuries or killed you instantly!
