I wanted to create something of such things beautiful and awesome. with conventional animation, decided to create three-dimensional. This idea originated long ago, but knowledge is clearly not enough, because it was necessary to operate a vast array of data. 8-bit AVR-stone seems can not do it, even looked in the direction of the percent CYGNAL. But I was wrong. And the proof - my draft fan with 3D animation. idea is as follows: a strip of 12 LEDs draw a picture in the same plane, taking eight of these strips and placing them at different heights, we obtain eight planes, together creating a 3-dimensional animation . central part of the design is a microcontroller ATMega48, clock frequency - 20MHz. The output produced by the LEDs in series with the help of shift registers 74NS164. All images and animation are stored in the memory card microSD. Pictures MC does not handle, transfer data from the card is directly in the shift registers. Pictures are made with the help of special software. MK only synchronizes the transfer, depending on the position of the LEDs.

The whole scheme consists of a main board and 7 more. Located on the main microcontroller ATMega48, 1GB memory card, shift registers, and 20 LEDs RGB. The remaining seven are located further to 12 RGB LEDs, 5 registers and the control transistor. The main board is located at the top, the rest - a step below about 4 mm. The signal from the photocell is supplied to the IC shielded wire.Power Card provides tps76333, matching levels using resistor dividers, current-limiting resistors on the LEDs no food for them, formed a hardware PWM, the capacitor at the gate of the transistor control needed to protect the LED for programming and other force majeure. The power supply system is implemented using an air transformer. The master oscillator assembled on a 555 timer. Power switch - IRF630. Primary and secondary windings contain approximately 90-100 turns of wire with a diameter of 0.35 mm.In a corner of the body drilled by an infrared LED, LED brand - any. All the elements are attached with superglue.
files for fans prepared a special program. Since the I really wanted to put the fan on the contest, but time was running out strongly, the program was a very crude sense, and now it does not spread. The failure occurred, and with LEDs - bought in our city the past, but 4 is not enough. Order in Moscow - not time-bound.
control program is written in CodeVision, post the complete project.
enclose a signet, pictures of the finished device, and video.
PS It was in a hurry to finish the fan until the end of the contest, so many flaws, but I plan to bring it to mind .
