You’re a very busy businessman/businesswoman, where you didn’t have time to mark down all the appointments onto the note! If you did, but you’re always forgotten about the location of the appointment and didn’t arrive it on time? Due to the mistake, you’ve missed the opportunity and even the customers’ entrustment on you!

You’ve learned the lesson and it’s time to overcome all the frustration. Fortunately, there’s a device that able to help you off.

Ladies and gentlenmen, let’s put your hands together for this Haptic Appointment Manager!

Ok, the device might looks a little bit simple (maybe ugly), but it’s a very powerful tool. Believe it or not, it capable to manage all of your appointments, ensuring thy arrive on time and in the right location.

The system is based on a GPS receiver and a compass. These two components are used to maintain awareness of its absolute and rotational position. You can interface it with a calendar of time stamped waypoints, and this system effectively guides the user to his/her appointments. All this can be done by simply vibrating in the direction of the next waypoint!

You’re the parent and your children seem to be have some deep interest on the robotics or electronics stuffs? Well, if they did, you might want to keep your kids busy with this Arduino Simple Walker!

For your information, this Arduino Simple Walker is the ideal little project to introduce your children to the Arduino’s world. This Arduino Simple Walker had already equipped with essential components. All your children have to do here is simply assembling them. The only material that you need to purchase is the Acrylic Arctic Ice (Frosted 1-side) 4.5mm.

Frankly, you have to pay attention on some of the steps here. First of all, please make sure that the holes to mount the servos onto the leg base is large enough, as you don’t want the hassle to drill these holes over and over again!

Once your children are done with the holes, it’s time to control the servos. In this case, you might want to use the standard “sweep” sketch, where is already included with the Arduino IDE.

Beside that, do mind about the servos, as different types of servos have different varying pulse rates.

If you have a job, where you’re needed to keep track of paper receipts, then it would be a disaster, if you discovered that a few of the paper receipts were missing here and there! You might be in deep trouble, especially when you’re being accused or blamed for missing the important paper receipts of company.

In order to get yourself out from this mistake, you might want to develop digital paperless receipt system. By using this digital paperless receipt system, all your receipts can now be stored automatically in one central location.

Well, the main purpose of this project is when a customer tries to make a purchase with a credit or ATM card; the transaction information will be automatically packaged and sent to a webserver. If the customer wants to view their transactions online, they have to log into a web interface to check on their previous transactions!

The cashier uses the keypad to enter an amount to be charged. Then, it displays the amount on the LCD display. The keypad is matrix encoded, thus it can only occupies 7 pins of the MCU.

Water, it’s one of the most precious and essential materials for all living creatures. You can survive without foods for more than 3 weeks or longer, but if you didn’t drink any water in three days consecutively, then the death is awaiting you for sure!

Unfortunately, many people have very low awareness about the water conservation. It’s maybe due to the environment, where there’s plenty of fresh and crystal clear water running through our home, once we turning on the water’s tap!

Believe it or not, in the next 50 years, water’s price will be bouncing high up to five times or more than today’s current price! In addition, many wars might be happened, due to the desire to dominate the clean and drinkable water.

Frankly, it isn’t hard to conserve the water consumption. All you need to do is build an automatic water meter that equipped with iobridge! This project is very easy and simple. It won’t be a problem at all, if you require some basic plumbing skill.

In this case, you have to install the water meter on your home’s incoming water line, which flips a switch for each gallon of water travelling through it. The switch creates electrical pulses, and then an ioBridge module will count the electrical pulses.

Love the Earth and show your concern on it, by building this water meter!

Some people might think, it’s impossible to packs a ton of smart features in a small package! Well, in this case, it seen that you’ve a little bit misunderstood about it. Due to the advent technology, many of the huge-sized electronic components have been modified and compressed into the smallest size, as it could be. Even, some of them can easily fit into the human brain as well!

If you always want to build a pocket-sized 8×8 Array that based on ATmega16, then you should check this project. For your information, this project is given name as “Hubik”, where is a very simple project and doesn’t require any resistors or transistors!

You’ll need two CR2016 lithium cells to power the ATmega16 and the AVR is using internal 8MHz RC oscillator. About the supply voltage, it’s better to be around 6.0V. Although lower voltages is fine, but the image isn’t bright enough, especially the green LEDs.

For this project, you have to connect a button to INT pin of ATmega16. The MCU will suspend itself automatically, if you press it for a while.

By the way, you might want to leave the ADC0 pin unconnected. By this way, you can simply edit the PCB and connect audio input to the ATmega16!
