It is a more powerful version of the “Mosfet Electronic Load Circuit LM358” project I shared, with 4 mosfets. When I got the 2-Mosfet circuit close, I did not bother..

“Cleaning the Desoldering Pump” was one of my duties during my apprenticeship years 🙂 Even though I don’t clean it as thoroughly as in those days, it still works. Note:..

A simple electronic siren circuit using the adjustable regulator integrated LM317T. Sound is produced with a 384 Hz square wave that oscillates approximately 9.8 Volts peak-to-peak. The RMS power of..

A simple but useful and stable circuit. In this state, it easily operates a 50W lamp without needing cooling. Of course, it got a little hot in my 100W experiments..

It is actually a simple circuit that makes a flip flop with three different opamp types. The PCB design of the elector is slightly different and the sockets used for..

A simple battery discharge protection circuit implemented with TL431, BC557 transistors and a small number of resistors. The power line is controlled with an N-Channel MOSFET instead of a relay,..

A project using RFID-RC522 module and PIC16F628A to perform access control with RFID Key cards. Adapted from Arduino “AcessControl” software. The PIC16F628A software is written in CCS C to work..

The TDA2030 Bridge amplifier can be used with a single source power supply. Working voltage DC 12V…. It is between 32V and can be operated with 12V battery, 24V battery,..

I did not like the PCB design of this application of Elektor and rearranged it myself. 🙂 There is even another variation of the same scheme on the site. (12..

TDA2005 is a classic integrated circuit that achieves great things with low voltage. You can use it as a stereo or bridge depending on its location. It does not hesitate..
