Tiny Basic Controller (TBC) is a simple device that can operate as a PLC (program logic controller) for home automation, control, etc. For example, this one can dial-up by modem to the remote computer and send the status of the controlled system, can control some processes, temperature regulation, battery charging, can be used for educations [...]
This project it is based around a PIC16F627 micro and It is build as a countdown timer for a UV exposure box for PCB development that uses fluorescent UV lamp with following features:
Adjustable time in 15-second increments (up to 10 minutes)
Lamp preheat feature
Two button operation (with audible feedback)
Countdown alarm (when timer reaches zero)
Relay for [...]
Samsung Electronics Co., South Korea’ s largest electronics manufacturer, unveiled a new refrigerator model featuring wireless fidelity (WiFi) capabilities designed by an Italian jeweler, the company said Thursday.The future begins today, and even refrigerators are already using the Internet, say in the Korean Samsung Electronics. The company today unveiled the most hi-tech refrigerator that can [...]
This driver may be used for a 3 Axis CNC Machine. Based on the PIC16F870, for 3x Unipolar(5, 6 or 8 wire) Stepper Motors. It provides Full Stepping for good torque, with ability to toggle auto-shutdown of motor coils, which allows the motors and current regulation device to run cooler and require a lower output [...]

How many times have you wished that you recorder your recent telephone conversation? I have, many many times. So thanks to [Trax] that he finally decided to make this happen by using PC and a piece of hardware (powered from USB) to record audio from phone line to MP3 format. He wanted this thing to [...]
The 78xx family is a very popular choice for many electronic circuits which require a regulated power supply, due to their ease of use and relative cheapness. When specifying individual ICs within this family, the xx is replaced with a two-digit number, which indicates the output voltage the particular device is designed to provide (for [...]
Three small simple audio generator, producing a square wave, sine and triangular outputs on three separate waveform selectable via a small three-position switch or through a small mixer single output. These arrangements are based on the use of an ASIC, the ICL8038 (Intersil or Harris), also available under reference XR8038 (Exar). This circuit contains almost [...]
mikroElektronika will be present at Embedded World 2009 in Nuremberg. You can find mikroelektronika at Booth 12-554, Hall 12. Embedded World 2010 Conference is presenting the leading European event for the Embedded Community covering all areas of Embedded System development.
Communicating wirelessly with your 3D-capable Samsung HDTV, SSG-2100AB Active Shutter glasses lighten and darken their liquid-crystal lenses hundreds of times per second in perfect coordination with the 3D content showing on the HDTV screen, allowing you to experience an incredibly vivid, lifelike, and of course, three-dimensional movie night at home.

This project allows instant start sequentially but a dozen low-voltage lamps 12 V / 60 W, and makes them fade and always sequentially (but slower). This system has been designed to meet the demand of a visitor who wanted ten recessed low voltage spot in a driveway to his house, with the following function: – [...]
This circuit allows switching on a LED when the battery voltage (12V) drops below a certain threshold. The operating system is based on a comparison of tension, which comes in a zener diode. If the supply voltage is 12V and the zener diode is a 10V model (this is the case in the diagram), we [...]
This is a good looking and practical device that can be useful in many areas where countdown timer is needed. This project is based on the PIC16F84A microcontroller. The time range can be adjusted between 1 and 999 seconds. This project has 3 buttons and one of them is named Set Button. In order to [...]
A VU meter is often included in audio equipment to display a signal level in Volume Units; the device is sometimes also called volume indicator (VI). In this project we are building a basic and low cost LED VU Metre circuit . The extent (range) display is -18 dBu to +3 dBu, spread over [...]
Today we have a new category “Projects” and a new electronic project 12 Channel LED Chaser with PIC16F84A.
This project is based on the popular PIC16f84A micro-controller.The heart of this project LED chaser is the PIC16F84A PIC microcontroller.A 4MHz crystal and capacitors C1 and C2 22pf is used for providing clock pulses to the micro-controller. The [...]
