World Of Electronics - Electronic projects

Instruction manual of an electronic moving font with LEDs and a clock built up of LEDs. Furthermore information is available about a serial-to-I²C converter, an AT89C2051 evaluation board and a complete TV tuner with an I²C interface."

World Of Electronics - Electronic projects

The LED moving font is built up of separate modules consisting of 64 LEDs each (8x8 matrix). The modules can be cascaced according to the desired size of the font. Each module is controlled by the LED display driver MAX7219 (or MAX7221) which can drive 64 LEDs.

AT89C2051 programmer

"Using this programmer you can program the internal flash of the microcontroller AT89C2051 from Atmel. The AT89C2051 programmer is connected via the serial RS232 interface to a PC. In comparison with other programmers, you do not need a special software, a terminal program is sufficient."

Other Projects here are  LED moving font, TV tuner, LED clock, Serial-I²C-Converter, AT89C2051/ATtiny2313 evaluation board, AT89C2051 programmer, I²C-I/O-Expander, AVR JTAG Emu, Displays.

MLAB - Mathematical and statistical modeling

MLAB is an ideal tool for mathematical and statistical exploration, and for solving simulation and modeling problems such as chemical kinetics, pharmacological compartmental models, etc.

MLAB - Mathematical and statistical modeling

Data Analysis and Modeling Services also available.

Free Induction Decay an MLAB Example

"Consider the following experiment: a 1 cubic centimeter sample of water at room temperature is placed between the pole faces of a 10,000 Gauss (1 Tesla) electromagnet. As the system reaches equilibrium, a small magnetic dipole of magnitude 3.4E-6 Gauss is induced in the sample parallel to the applied field. "

The Control of engineering systems

PID Controller Design - "We used a 3-stage fuzzy logic PID to control our system. The kp, ki and kd values were changed depending on the current status of the error signal. For error values above a certain percentage of the desired output (in our case it was 30%) we used a large kp constant to drive the system as hard initially to get up towards the desired final value as quickly as possible...."

For error values above a certain percentage of the desired output (in our case it was 30%) we used a large kp constant to drive the system as hard initially to get up towards the desired final value as quickly as possible.  This results in saturation of the amplifier."
