This project is a result of needing to service a domestic electronic item without being able to obtain a circuit diagram. The process proved to be very long and painstaking, but also very rewarding.  The steps presented here are not exact, and you will no doubt find your own way of working which is more [...]

Finally I found some time to create a project, I explored the google and I found one page with an interesting scheme on VGA interface.   So I made the pcb with eagle and I made it with the toner transfer method.   This project uses few parts, one microcontroller PIC16F84, one capacitor 100pf, one [...]

After some weeks without any free time for new projects, i give you my new led tester with brightness control. From time to time i need to test some leds and before i had a battery with a resistor hanging on to teste them. This is by far the worst solution to have on my [...]

Yesterday I went to Skopje and bought a True-rms Multimeter Fluke 175 from loging.mk , they have a discount on Fluke Digital Multimeters,before them I had a Mastech 8201 and Mastech  343.  And here some features of Fluke  170 series digital multimeters: True RMS voltage and current measurements 0.09% basic accuracy (177, 179) 6000 count [...]

Happy New Year In the New Year to you and your loved ones wish you health, happiness, satisfaction, and that you realize all those greens in large and small ones. Happy Holidays and Time with my family:

This ESR Meter I made it somewhere in 2007, and now I have only made the box still miss him to make him a mask. A lot of it is accurate and now for now is doing great. I made it from magazine Emiter 6nr 2004 year, the PCB can be bought from the magazine [...]

Just wanted to wish you all a Merry Christmas, Happy Holidays, or a Happy whatever you are celebrating at this time of year.

If you dont have some idea how to organize your electronic workbench you can get it from here, my friend D-r Avramovski Petar writer for magazine Emiter   has sent to mi  beautiful pictures from his electronics laboratory. So enjoy.. Thank you Petar.

How to convert ATX power supply into a bench supply.The power supply is based on an old pc ATX power supply. This is great because they are cheap, efficient and provide a huge amount of current on demand. He add an external voltage probe and a switch to allow voltage measurements either from the ammeter [...]

Tehnikservice.net completes three years of its existence today. We have a long way to go together. I have planned many new features, products and services also new category repairing section from tehnikservice.net – some of them would be launched soon, and some would take a couple of months. But I assure you that all of [...]

This project is a floor lamp that can take the color and brightness as desired. Adjusting the brightness of each group is provided by a generator whose frequency is fixed but whose duty cycle (temporal relationship between high and low) is variable, much more efficient than setting current variation in LEDs. It consists of a [...]
