Hello Guys, from the past few months I have been looking for a bench power supply for myself. But looking at their prices I decided to build one for myself. This power supply costed me around 25$ (approx 1700 INR). The main power supply used here is an old SMPS from a desktop computer.
Like every bench power supply this one also has variable voltage and current limiting feature. It also has fixed voltage outputs.
Watch the complete build video on YouTube.

Below I have added some pictures of the build from my website. You can follow the step by step tutorial there. Also the circuit diagram is on my website.
