Digital Defocus – Super Cool Flashing Clock!

Ok, maybe it isn’t a big deal for most of you here, as you might be very familiar with the digital clocks. However, have you ever tried to build a super cool flashing digital defocus clock by your own? Well, if you haven’t, then it’s the best moment to test out your ability and building skill… For the project, a Dorkboard is going to be used as the microcontroller. Honestly, it’s an Arduino system, which is based on the Atmel ATmega128 microcontroller. The real time clock is made with the use of a DS1307 board with battery backup. It’s a very important component, as it can be used to communicate with the Arduino using an I2C interface. A MAX7219 LED driver IC is necessary, as it has the ability to… Continue reading

The Cheap But Useful Ericsson Cell Phone Display GA628

You used to have an Ericsson Cell Phone GA628 and you also loved it very much, however after few years of using, you’ve decided to change a brand new cell phone and you just threw it inside the drawer and never touch or look on it after that? Well, instead of leaving it in the drawer, why don’t you reuse it and give it a nice little modification here? This project wouldn’t cost you too much, as it is a cheap and power saving simple display for battery powered, thanks to the help of Ericsson GA628 display. Since it’s a readily available and the I2C interface allows the connection to a very small microcontroller as well! The GA628 display will provide a 12 character alphanumeric display, where some of the… Continue reading
