For that, Clem opted for multiple 2000mAh LiPo cells, instead of a single large one. To achieve the necessary voltages (3.3V@1A, 5V@2.5A, and 12V@0.5A), Clem faced the complexity of generating multiple voltages from a single-cell source. This involved designing a switching converter, a task he had never done before.</span><span>&nbsp;</span></p> <p><span><img alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/vlcsnap_2D00_2024_2D00_01_2D00_31_2D00_16h16m33s868.png" /></span></p> <p><span data-contrast="auto">Troubles arose when attempting to parallelize the step-up converters. Clem&#39;s initial approach faced issues with voltage regulation and load-induced voltage drops. The struggle to balance multiple step-up converters led to unexpected challenges, impacting the overall system&#39;s stability. Despite successful testing of the charging circuit, integrating the system with an actual computer brought about further complications.</span><span>&nbsp;</span></p> <p><span><img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/vlcsnap_2D00_2024_2D00_01_2D00_31_2D00_16h16m41s977.png" /></span></p> <p><span data-contrast="auto">Clem wanted to use a Sudosom module; however, development wasn&rsquo;t quite complete. This prompted a switch to a Raspberry Pi Compute Module 4. However, the step-up converters failed to deliver sufficient current, causing the voltage to drop and the computer to brown out. Even switching to a CM4 Lite did not resolve the problem.</span><span>&nbsp;</span></p> <p><span><img loading="lazy" alt="image" style="max-height:360px;max-width:640px;" src="/resized-image/__size/1280x720/__key/communityserver-wikis-components-files/00-00-00-04-35/vlcsnap_2D00_2024_2D00_01_2D00_31_2D00_16h17m04s255.png" /></span></p> <p><span data-contrast="auto">In a last-ditch effort, Clem used resistors in an effort to control the voltage, but realized that the project demanded more expertise in power supply construction than he currently possessed. The undertaking highlighted the distinction between tinkering and engineering, emphasizing the need for precise measurements and in-depth knowledge in the latter.</span><span>&nbsp;</span></p>

2 posted to Documents by tariq.ahmad on 1/22/2024 5:20:11 PM<br /> <p>Where does tinkering stop and engineering begin? Clem challenges himself to build his magnum opus, a laptop from scratch. While the project starts on a fast pace with the keyboard already built in a previous video, he soon discovers where the line is drawn between casual Makers and Engineers. To overcome the steep learning curve of power supply design, he has to design his first ever step up converter and find a way to put multiple converters in parallel. Charging and protecting multiple cells is a challenge in itself, but Clem has a plan. Will this project break him? Or will it put him on the way to learn proper engineering?
