Earlier this year I bought some PA speakers at auction. The auction company was cagey enough to list them all as “untested / condition unknown,” but I suspect they had a pretty good idea of the condition.I ended up with a Yamaha SW1181VS 18? 500W subwoofer, a Yamaha Yamaha CW218V dual 18? 1220W subwoofer, and [...]
I just wanted to wish a happy new year to all our readers, and I am sure 2010 will be an awesome year for everyone.
26.11.2008 Is a very special day for me. I became a father to a beautiful princess .Beside that www.tehnikservice.net is celebrating its first (1) birthday.

Book Description
Todays control system designers face an ever-increasing need for speed and accuracy in their system measurements and computations. New design approaches using microcontrollers and DSP are emerging, and designers must understand these new approaches, the tools available, and how best to apply them. This practical text covers the latest techniques in [...]

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 [...]
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 [...]
