Exposure
If everything is printed out correctly on the test page print it out to a transparency using a Laser printer to the maximum resolution, cut the PCBs from transparency and keep them in good condition until development. Your hands must be clear and you must don't tough it on top of traces.
You will need:
- Exposure chamber with UV light 300W
- 2 pieces of glass 30x30cm, thickness 0.5mm
- Peridrol (from local pharmacy shop)
- Sparse Hydrochloric acid (form Super Market, used in baths)
- Plastic gloves
- UV Light sensitive boards
- Protective Laquer spray
- Drill with drill bits form 0.5mm to 3mm
- 2 plastic basins

Processing in Photoshop
Open Photoshop and click Open, find file BlinkLed.bmp and click Open, the program wil open the PCB you created using Eagle.
As you can see the PCB traces are white and the empty space is black, that must be inverted because we want to print out the traces.
To achieve this we use the Invert command, click on Image - Adjustments - Invert or use the shortcut keys CTRL+I on your keyboard.

Making your own PCB's is a procedure that needs extreme care so the result become useful. Many times you faced up the challenge to print out your own PCB's many times or many different PCB's in one sheet. In this article we will discuss how you can do this combining common software tools. Also we will discuss hoe to print out PCB's from Elektor magazine along with your own custom made PCB in one transparency, after processing it using Photoshop CS for better results.
The software tools you need are:
- Adobe Photoshop CS (image processing).
- Adobe Acrobat Reader (PDF files reader).
- Eagle Layout Editor 4.11 Freeware (available at their website)
89SXX Development Board
Introduction
There are some 89SXX development boards, here is another one. I have designed this single side development board to be used as a tool for learning MCS-51 Microcontrollers, and for easy microcontroller project development.

Programmable Home Security Alarm System
Introduction
In this project we design low cost high performance programmable home security system. This system uses a few LDR's as input sensor. When above sensor(s) get triggered system may dial the user specified phone number (using built-in DTMF generator) and activate the high power audio alarm an lights. All the parameters of DTMF generator , audio alarm and light interface programmed through the RS232 serial interface.

I2C Protocol Implementation With RTC And EEPROM
The main aim of the project is to implement the I2C protocol by interfacing RTC and EEPROM using controller (ATmega8535).
ISDN Tutorials
1. Overview
ISDN is a digital communication networks providing transmission rates in multiples of 64 kbits/sec. Typically described as 2B+D, Basic Rate Interface(BRI) logically used 2 64kbit/s data channels (B channels) and one 16kbit/s signaling channel (D channel). ISDN has yet to become a single global standard. Individual countries however, have their own flavors of ISDN all of which are based to a varying degree around the ITUs ISDN standard.

Remote Controlled Spy Car
Abstract
We have seen bluetooth controlled car before this. Today we are going to see remote controlled spy robotic car. Here is the block diagram of remote controlled spy car. Applications of this car are this car can capture picture, can record audio as well as video using wireless remote controller i.e. using RF signals. Maximum range of this robotic car is 125 meters. It overcomes with limited range of infrared remote controllers.
Bluetooth Car
Abstract
Today’s
RC toys are controlled by a single dedicated (and often proprietary)
controller. We endeavored to develop a
remote control car that would be controlled via Bluetooth wireless technology. Since Bluetooth is a standardized and
relatively reliable wireless protocol, we hoped to create a car controllable by
any Bluetooth device. Additionally,
Bluetooth consumes low power and has a larger bandwidth than the standard
900MHz RF link which drives most toys. This
added benefit allows for sending of complex information from the car to the
controlling device—something unseen in consumer grade RC cars. Our computer-controlled Bluetooth car demo
showed the feasibility and practicality of Bluetooth controlled devices while
also revealing limitations in the amount of data transmission capable by
commercially available Bluetooth options.
Thermometer using Microcontroller
Introduction
- This article is about a simple 0-100°C digital thermometer using Microcontroller.
- The circuit is based on LM35 analog temperature sensor, ADC 0804 and AT89S51 microcontroller.
