Build Electronic Circuits Like a Pro

If you want to build electronic circuits, you need to connect the components of your circuit somehow. If you expect to make your circuit work more than just a few times, you need a solid way of connecting them. You need to create a printed circuit board (PCB).

"I started playing with electronics as a hobby when I was 14. Since then I have finished a Master's degree and founded two electronic design companies."

The radar sensor uses a Ultra-Wideband (UWB) chip from Novelda. It sends out electromagnetic pulses and analyzes the pulses that are reflected back. In the video above, a part of the electromagnetic pulse will be reflected back when it hits the wall and a part of it penetrates the wall and is reflected from the cabinet behind the wall.

CLOCK

Six Digit LED Clock Display - The board is driven by a Maxim MAX7219 which has a serial interface; it can be controlled by a any microcomputer with a SPI or three output lines. The board is 2.75 inches by 6.5 inches in size; mounting four .8 inch LED displays and two .56 inch displays as well as six individual LEDs, a 7805, the MAX7219, and a five pin header.

MC9S08SV16 Arduino Form Factor Board


The project board is for folks who, for whatever reason, want to use a 9S08 microcontroller but also would like the convenience of using one of the many Arduino shields.  Bare in mind that this is a MC9S08 microcontroller board and is in no way software compatible with Arduino.

Z80 Family and ZiLOG Semiconductor

ZiLOG Semiconductor

Founded in 1974 by Federico Faggin, the inventor of the world's first microprocessor, ZiLOG builds semiconductor products  that enable design engineers to break through the barriers to creativity and innovation in embedded design.

Zilog - Wikipedia

ZiLOG is the inventor of the award-winning Z80 and Z8 microchip architectures that have been embedded in over a billion end-use devices worldwide. Companies get more innovative products to market faster because ZiLOG products and design tools help them turn their imagination into consumer appliances, remote controls, vending machines, telecommunications controllers, home automation systems, spacecraft instrumentation, industrial automation systems, and thousands of other products.

Thomas Scherrer - Z80-Family

"This page contain docs, FAQs, source code, (cross-)assemblers, (cross-)compilers, utilities, etc. as well as links to other Z80 relevant stuff. Some of the info found here is property of Zilog, like hardware docs, instruction sets, and some of the software available."

WZMicro - Affordable Quality Electronics

The Z-80 SBC

Combine The Z-80 SBC and SB8466 interface card, you will have a full embedded controlled system, you can use it in any project you can think of, it is only limit to your imagination! .

The SB8010 is a highly versatile SBC comprised of a Z-80 microprocessor, 4 general purpose 28 pin sockets for byte-wide ROM and/or RAM chips, a Z-80 CTC counter-timer, and a serial I/O port (UART) using Intel's 8251. A bootstrap option is provided for loading an operating system into main memory using an on-board PROM.

On-board memory can be mapped in various ways to match the memory chips selected. The mapping options are accomplished using a PROM. The user may install his won PROM if a different mapping is desired. However, the six mappings provided should satisfy most users.

Connecting the Easy-Downloader V2.0 to a PC with USB port:

Programmer  for AT89S52 Microcontroller

Newer PC, or laptop computer may not provides the COM port, instead it has the USB port as a standard serial port. I found a cheap adapter, the FTDI232 USB-COM port converter. The adapter uses FT232RL chip. The adapter provides 6-pins connector. To interface it to the Easy-downloader, we needs only three pins, i.e. TXD, RXD, and GND. The chip itself powered by +5V from USB port.

Coprolite Homebrew Computer Construction and Electronics

The first microcontroller I became fascinated with was the 8048 (and 8748). This site has a lot of info on the 8048, including an 8048 Development System.

Coprolite Homebrew Computer Construction

From Hyper Embedded - Microcontroller ASIC and EDA

8048 The One who started it all ….

The roadside attraction of this site is the Z-80 Homebrew Computer. This was a project that I started in 1980. I moved many, many times between 1983 and 1996, and the project often was shut up in a trunk. In some cases I lost (or gave away) most of my equipment and parts. I finally got the full homebrew computer working twelve years later on several breadboards, and soldered it all up in 1993. It took me another ten years to document the system. It has been a fun ride.

diy4fun - Miroslav Batek Czech Republic

diy4fun - Miroslav Batek Czech Republic

diy4funThis is versatile development board for AVR microcontrollers ATmega48/88/168. It is good for testing and debugging embedded programs. It has many built-in peripheries connected to microcontroller so you can use them without soldering. ATmega microcontrollers are produced by ATMEL and they include a lot of features: I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Oscillator, EEPROM… These microcontrollers are very versatile, easy to program and easy to use. This is the reason why I like these microcontrollers and why I decided to make development board for them.
