The American QRP Club

The American QRP Club

The American QRP Club was formed in June 2003, and later incorporated, as a organization of ham radio operating enthusiasts interested in low power operation - these types of hams are called QRPers. The AmQRP Club is not affiliated with any geographic area and its membership does not meet monthly as do many regional radio clubs. Instead, the AmQRP provides online information, instruction, goods and services to the general QRP population for educational and enjoyment purposes.

Meggy Jr RGB - EMS Laboratories - Hobby Electronics

Unprecedented Innovations from a young group of Scientists who may change the way we interface with the Electronic Environment around us.

Meggy Jr RGB is a new kit that we designed as a platform to develop handheld pixel games. It's based around a fully addressable 8x8 RGB LED matrix display, and features six big fat buttons for comfy game play.

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.

GMC75X Credit Card Microcontroller

Ideal for those small jobs where a standard embedded controller can't be justified. The GMC75X is like a "BASIC Stamp" except that you can program the module in 'C' using C-FLEA and a download cable. Alternatively, use 8051 assembler.

Design Experience

"In the early 1980's, products were designed using the Zilog Z80 micro-processor. These ranged from a simple sequence controller to one of the world's first all digital DC motor controllers. Single and 3-phase 240Vac and 415Vac fully regenerative models were developed. Some are still running today! A common application area was paper and film conversion machinery."

TRCY robot combat competition

"This is sponsored by The Robotics Club of Yahoo which is an ecclectic collection of robot haves, have nots and beginners. It runs using the Parallax Basic Stamp II controller on one of my Stamp II boards. The code is one based on the principles of Subsumption Architecture by using finite state machines to simulate a multitasking environment - here's the code. Here is the Subsumption network diagram."
