Well everything comes from China so I did some &#8220;research&#8221; on the most common websites. I found a module that makes a positive and a negative voltage from a single 12V supply. I found out that the positive supply was the one that needed some current in order to regulate. This was accomplished by a resistor. The negative voltage has the same value as the positive so an extra 7905 regulator was needed. Advantage is that you can adjust the positive output as well!<\/p>\n\n\n\n<p>Lazy builders power supply!<\/p>\n\n\n\n<p> <\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"740\" src=\"https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/12-5V10V-1024x740.jpeg\" alt=\"\" class=\"wp-image-1748\" srcset=\"https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/12-5V10V-1024x740.jpeg 1024w, https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/12-5V10V-300x217.jpeg 300w, https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/12-5V10V-600x434.jpeg 600w, https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/12-5V10V-1536x1110.jpeg 1536w, https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/12-5V10V-2048x1480.jpeg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"480\" src=\"https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/5-van12V-2-1024x480.jpg\" alt=\"\" class=\"wp-image-1749\" srcset=\"https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/5-van12V-2-1024x480.jpg 1024w, https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/5-van12V-2-300x141.jpg 300w, https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/5-van12V-2-600x281.jpg 600w, https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/5-van12V-2-1536x720.jpg 1536w, https:\/\/pa3csg.nl\/wp-content\/uploads\/2023\/04\/5-van12V-2-2048x961.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Second attempt to get a positive and a negative voltage from a 12V supply came from a youtube item, someone using the LM2596 Chinese boards for that.
