PIC Microcontroller Architecture and Applications

PIC microcontroller was developed in the year 1993 by microchip technology. The term PIC stands for Peripheral Interface Controller. Initially this was developed for supporting PDP computers to control its peripheral devices, and therefore, named as a peripheral interface device. These microcontrollers are very fast and easy to execute a program compared with other microcontrollers. […]

Circuit-Zone.com – Electronic Projects

For a long time I needed a good programmer pussy, even if it is programming, so from time to time the application gets where it is used. So I decided to build the programmer. I chose between a couple of projects from different authors, but eventually won PICkit2. Microchip released the schema directly in the

In-Circuit debugger, created by E.E. Atanasios Melimopoulos using PIC16F628 microcontroller

This project was sent by Electrical Engineer Atanasios Melimopoulos (Copyright (c) June 15, 2007) INTRODUCTION: In-Circuit-Debuggers, as you may already know, have become the PIC’s debugging standard tool for many programmers because it’s easy use and handy interface to the target picplaced- board. They come with MPLAB plug-ins that provides a full rich set of

Electronic Quiz Buzzer Circuit Diagram using PIC Microcontroller

Usually high level quiz competitions are very much time-oriented as it becomes significant to determine who has answered first. So here we’ll see how to make a buzzer system that helps to decide the winners. Actually I designed this circuit of buzzer for quiz program conducted in our area and then I thought it may

How to set up your B&W Zeppelin Air

With the B&W Zeppelin Air being such a popular iPod docking station as well as a fantastic AirPlay compatible device we thought it would be a good idea to write a ‘how to’ on setting up your new Zeppelin Air. As of September 2012 newer machines are installed with a slightly newer firmware version. The

PIC16F877 Development Board v. 1.2

The Development Board v. 1.1 connected to an LCD display. It is well visible (read further, in the description) the row of LEDs used to check the logic state of up to 8 I/O ports or external circuits’ pins. Of course, if you own an 8 trace oscilloscope, you can do without it. :-)) On

Marantz CD63SE laser transport mechanism replacement

An elderly, but still sought after Marantz CD63SE was bought into the shop last week, with the fault reported that CD’s would no longer play. After approximately 15 years of use, this is a common situation, as the laser power will gradually reduce over time to the point where it can no longer focus reliably

Repair of Arcam CD73 laser mechanism

This 2004 vintage Arcam CD73 came into us with the reported fault that it would no longer play CD’s, or even read the table of contents. Given that it is over eight years old and had plenty of use in that time, we were not surprised to find that the laser had expired and needed

Alchemist Forseti APD15A RC Integrated amplifier

We recently had a customer present this faulty Alchemist Forseti integrated amp for repair – I’d guess this dates from the 1990’s and has been well looked after. It’s a bit of a bruiser as you can see from the extensive heatsinking! Unfortunately it developed a DC fault on the loudspeaker outputs and destroyed the
