Hello. The aim of the film is to present solutions that will be able to be replicated by almost anyone whose skills allowed them to find this material on YT and whose level of concentration allowed them to watch the material from beginning to end. I decided to tackle the modification of accidentally found ATX computer power supplies so that it would be possible to smoothly regulate the output voltage. What I show in the film is a form of extremely primitive, maximally simple interference of the computer power supply converter so that the desired effects, i.e. changing the output voltages, can be obtained in an extremely simple way. Such power supplies are available for small change in scrap metal shops or exhibitions of old computers, so they can be called rubbish in the form in which they were manufactured, after a primitive modification they can become fully functional tools for work or play. Can a randomly found power supply be easily modified? So that it is suitable for charging a battery or powering various devices? I will try to check it, I am waiting for your suggestions and ideas in the comments. To do it professionally, expertly, I recommend studying materials on this topic, e.g. from the RS Elektronika channel: • TL494 [RS Elektronika] #53 #regulatedpowersupplyfortx #universalregulatedpowersupply #regulatedcomputerpowersupply
