Setting up an electronics lab is the dream of many electronics engineers and hobbyists, but getting it done is usually a very big task to achieve. From knowing the amount of space you'd need, to know the right kind of tools to buy, and then to the right kind of devices with the right...

This project is a solution to power up most devices or projects requiring dual (+/-) adjustable power. The circuit consists of a stepdown transformer, bridge rectifier, DC filter capacitors, LM317 positive and LM337 negative adjustable voltage regulators, 2 x trimmer pot for independent...

This project is based on STK984-090A which is a fully-integrated inverter with current rating 20A and supply voltage 40V DC. It has been designed to drive the Brushless DC Motors (BLDC) and permanent magnet synchronous motors (PMSM), the module works as output driver which include power...

This is a multi-output power supply based on LM2576HV-ADJ and LM317 IC. The power supply provides 3 outputs with input supply up to 55V DC. Output (O1) is adjustable up to 24V DC and load current of 2A, Output (O2) is adjustable to 1.2V-24V with load current up to 500mA and Output (O3)...

Zak Kemble build another great project. This time it's a bench power supply with a laptop brick input. The power supply needed sufficient cooling so he added a small Fan and a controller a the edge of the board. He writes: Many years ago (September 2009) I made a simple bench power...

This board provides 12V/200mA DC and 1.2V to 6V/500mA DC Adjustable output with input of 7.4V 2x LiPO batteries.  The board is a step up DC-DC Convert based on CS5171 and LM317 adjustable regulator. The Step up DC-DC converter provides 12V DC from 7.4V ( 2x LiPO batteries) and LM317...

The circuit presented here is based on LM317. Generally, LM317 is known as a linear regulator IC, but here the circuit operates as a switching regulator. This circuit operates by transferring energy from the input to the output by using a solid state switch. Power Efficiency of a...

This project is a solution to power up most of devices or projects requiring dual (+/-) adjustable power supply. The circuit is based on LM317 positive and LM337 negative voltage regulators. LM3X7 series of adjustable 3 terminal regulators is capable of supplying in excess of 1.5A...
