Coffee + arduino + LEDs the new morning three in one

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. Continue reading

The Extreme Fun With tinyCylon Kit!

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.… Continue reading

Decorate Your Home With This Sparkling Christmas Lights Controller!

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… Continue reading

Colorful and Fully Remote Controlled RGB Light Bulbs Lamp

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… Continue reading

Mini Flash – It Might Be Tiny But Powerful!

You’re bored with the recently projects and you like something different? Ok, how about the “Mini Flash” here? Would you like to keep yourself busy with this creative and innovative project? For your information, Mini Flash is a programmable LED Sequencer/Flasher and it’s based around the PICAXE 08M microcontroller. Well, it’s a spin-off of the Pro Flash Programmble LED Flasher/Sequencer, which is based around the larger Picaxe 18X microcontroller (Well, larger doesn’t mean better, isn’t it?) Theoretically, the Mini Flash will sport the same features, as the larger Pro-Flash controller. The only difference here is it can only control 4 LED channels instead of 8 LED channels. The controller is well programmable in a BASIC-like language, where it’s very similar to the “Basic Stamp.” Beside that, the ability to reprogram the LED sequencer by using a PC-based program is one of the specialties of this project. In fact, the servo lead, which is normally plugged into a spare channel for control, is also being used to reprogram the Mini Flash Flasher/Sequencer via a computer’s serial port connection and programming cable.… Continue reading

This Fireflie NG is Awesome!

Have you ever saw the synchronizing Fireflies NG before? The most significant view of this Fireflies NG will be the big white ping-pong ball, which it has to be attached on the PCB (The ping-pong ball creating a very awesome view for this project). If you’re always wondered how to create a Fireflies NG, then you’ll have the chance to do it today! Basically, this is a synchronization project, where it can be flash randomly but after some time and influencing each other, they’ll flash in sync frequency. Small microcontrollers will be used in this project to simulate the fireflies. You must pay attention that each firefly acts autonomously and it is not a preprogrammed pattern. In other word, it is more like a self organizing system! The NG version is uses a small PCB or Printed Circuit Board and a RGB-LED. Since each of the firefly has its own value that stands for the power to flash and the value is rises over time. Which mean, if the power reaches a certain limit, the firefly will flash and the… Continue reading
