• Drive dot LED matrix display using LPT port and driver IC
  Interesting projects on how to drive multiple dot LED matrix displays using LPT port and Led matrix driver cirtuits. Step by step explanation how to start your own system.
  It is convenient to drive dot LED matrix displays using IC drivers of 5×7 dot LED matrix’s like MAX6952 and MAX6953. These two IC’s differ only by data interfaces: SPI for MAX6952 and I2C for MAX6953. In this article you will se how these driver IC’s can be controlled by computer using LPT port.Program provided [...]

• Power up your electronics using potato batteries
  Did you know that potatoes can generate electric power. Check this out.
  Thomas Pfeifer does something new and amazing every day. This time he demonstrates how simple digital clock or LED diode can be powered by using batteries made of few potatoes and two different types of metal (iron and coper). Demonstration shows that such battery made from single potato generates 0.848V voltage and is able to [...]
