On the Internet, atmel, microchip series microcontrollers with a lot Led cube has a project in this application one of them, but diagrams, photos, supplemented with a detailed description there thanks to this project Led cube understand the logic may be easier to floors circuit diagram and C source software provided.
5x5x5 LED cube dimensions 512 x red leds placement of the LEDs will be a bit erratic but it has involved a lot of precise soldering LEDs 🙂
Led cube of the main materials used in the circuit outside ATmega32 CD74HCT238 decoder and 74LS04 Hex Inverter

HDD Brushless Motor driver Circuit Atmega8
Brushless motor drive circuit used in computers hard drive with Atmega8 checked the engine ATmega 8 output MOSFET (IR4427, IRFZ44) strengthened engine with A, B, C, D, attached to either end. Software is written in C language compiler used in CV AVR application circuits for frequency crystal oscillator is used but instead of the internal crystal oscillator recommend testing for long-term operation of the motor is estimated that 30,000 of cycles.
