<p>This is a remix of the awesome <a href="https://www.thingiverse.com/thing:2085223">Lab Power Supply</a> by Chordless. I couldn't find the exact components they used, so I had to adjust the design a little. I also added separate switches for the input and output so you can adjust the voltage or current without the need to disconnect your electronics.</p> <p>Here's the list of parts I used:</p> <ul> <li>1x <a href="http://s.click.aliexpress.com/e/b7ZCKEOM">5A CC StepDown Board based on XL4015 E1</a> 1.51 EUR</li> <li>1x <a href="http://s.click.aliexpress.com/e/nr6qhIg">Mini Digital Voltmeter Ammeter DC 100V 10A</a> 2.33 EUR</li> <li>2x <a href="http://s.click.aliexpress.com/e/cr2Y3eJe">WXD3-12 10kOhm Potentiometer</a> 2.04 EUR</li> <li>1x <a href="http://s.click.aliexpress.com/e/3r54BTi">KCD8 Rocker Double Switch</a> 0.59 EUR</li> <li>1x <a href="http://s.click.aliexpress.com/e/1FfbhJE">2.5mm DC jack</a> 0.14 EUR</li> <li>1x Set of <a href="http://s.click.aliexpress.com/e/1fpm4qG">red and black Terminal Connectors</a> 1.06 EUR</li> <li>1x <a href="http://s.click.aliexpress.com/e/qLs5wko">Test Leads</a> 2.70 EUR</li> </ul> <p>This was a very fun project for 10.37 EUR.</p> <p>For assembly instructions follow Chordless' description and refer to the schematic.</p> <p>Again many thanks to Chordless for their original design, to Heartman for their <a href="https://www.thingiverse.com/thing:1264391">Parametric Box</a> and charliearmorycom for their <a href="https://www.thingiverse.com/thing:54024">Customizable Knob</a>.</p>
