Beware of These Scary Servo Eyeballs!

If you’re so damn bored with your life and would like something more thrilling or spooky, maybe this scary shifty servo eyeballs might be the perfect choice. Before you build up the project, there are several components that you need to prepared and there are: Two toy eyeballs (Honestly, the ping pong balls that painted like eyeballs are well suited as well) Two small servos (HXT500 version) A standard servo An Arduino with tiny breadboard rubber-banded on top Two BlinkMs (One for each eyeball for running a custom light script) Hot glue, Popsicle sticks Some wires, and Arduino sketch. Ok, let’s get started. First of all, you must glue down the smaller servos for the eyes to a base, glue a servo horn underneath the base and then plug it into the larger servo. After it, apply the two servo horns for the smaller servos, glue each eyeball to a servo horn and snap the eyeball (with horn) onto the smaller servo. You can drill or even poke a hole in the back for the LED and hot glue the… Continue reading

The Outstanding Arduino Strobe Algae Bioreactor

We all knew that Arduino is definitely a very special electronic device, as you can do many incredible electronic projects with a simple arduino! Well, if you’re looking for a home décor, but you don’t want to spend huge money out from your wallet, maybe this fantastic Arduino Strobe Algae Bioreactor is your ideal choice. Why? Believe it or not, the Arduino Strobe Algae Bioreactor is only cost you about $60 and less than three hours to accomplish it! Honestly, you don’t need to be an expert to build this project, as it only require basic power tools. For your information, algae has been recognized as one of the most potential environmental friendly powers, where many researchers have been involved in the algae experiment to cultivate the unknown parts of algae. In this project, it’s a very easy one, where you use a platform for one technique that is broadly used with to trick the algae into reproducing. The algae species reacts differently in many ways to its environment. You can create a microcontroller platform that can be variably set… Continue reading

The Magical Reverse Geocache Puzzle Box

If you’re happen to be a vivid traveler who loves to travel frequently, you know that it’s totally a very painful experience, especially when you cannot locate the exactly destination that you want to go to… Well, most of the experienced travelers overcome the above problem by using the GPRS, as it’s by far the best system that we can use now. By the way, if your friend had decided to get married in another country and you don’t know what is the best present for him/her, maybe this magical Reverse Geocache Puzzle Box would be a nice gift for your friend. For your information, the Reverse Geocache Puzzle Box is definitely a very interesting present. Go figure, what your friend will think, if they received a book-sized wooden box that beautifully carved with elephant images (Well, it doesn’t has to be an elephant, as you can change the pattern accordingly). The most special part is it’s mounted into the lid and with an illuminated button. It has a small display on the top and the reader has 50 attempts… Continue reading

POV Globe that Based on Arduino and 72 SMD LEDs

If someone telling you that you can build a POV Globe, by only using an Arduino (ATmega328P) and 72 SMD LEDs, what is your first expression? Honestly, you might be feeling shocked and didn’t believe on it, isn’t it? Well, sometimes, you can turn the impossible into possible, with a little bit of efforts. Ok, let’s cut the crap and jump into the project right away… For your information, this POV globe is based on an Arduino (ATmega328P), which is capable of displaying monocolour bitmaps upto 72 pixels high and x width. The 72 LEDs allow the one input to get rotation speed instantly. The Arduino byte array for the images is generated using the C# program, while the image displayed is synchronized to speed of motor using a reed switch. It enables the images to display around whole globe correctly. Also, it can maintain a constant position of the rotation as well. Please keep in mind that the reed switch must be hot glued to globe cylinder. Beside that, you should keep your eyes on the magnet, where you… Continue reading

The Easy Ways to Drive USB Keyboard from Arduino

If you’re wondering, “How can I drive USB keyboard from Arduino? Does it require a lot of complicated steps?” In this case, you should stop by and read on this article, as we’re going to show you the easiest ways to solve up this problem. Normally, a keyboard is hard to use, if results of typing can’t be seen on the screen. Well, the first step is to add an output device. You might want to use the LCD high-level routines and develop low-level functions that specified to MAX3421E hardware. Since the function syntax is identical to official LCD functions, the user manual is already written and can be easily found in the library reference by title “LiquidCrystal”. You will notice that the only difference is in the constructor, where only 4-bit mode is possible and only one pinout is supported, the Max_LCD constructor is not accepting any parameters. The LCD data lines are driven directly by 3.3V logical levels of MAX3421E, while the VDD is connected to 5V. By using this method, the LCD contrast can be adequately biased.… Continue reading

Arduino Step Sequencer Synth aka Noise Box

You’ve always want to build an Arduino step sequencer synth, but you don’t know the proper way to develop it? Well, you can end your searching now forever, as you’re having the chance to get closer with the Arduino step sequencer synth. For your information, it’s a simple Arduino step sequencer synth. It has a maximum of eight tracks. Each of the tracks has eight patterns and each of them has a maximum of 16 steps. In this case, you can assign a MIDI input and output channel to each of the track, by choosing a play and record mode for each track. There are three play modes, which as: The first track has one Note only. It’s a good note for the drum computers, as you only need to set the step active or not. The second one can store a note in each pattern, perhaps for chord sequences. The third can be used to store a note on each step and it’s also the best mode of all. Believe it or not, you can plug in a midi… Continue reading
