See what you can DO with old ELECTRONIC CARDS that no longer WORK!! In this video tutorial of Easy electronic projects with MOTORS, experiments, homemade tools and much more!! we will see what we can do with old electronic cards that no longer work, the first thing we are going to do is discharge the largest electrolytic capacitor since it can remain charged with a high voltage and can be dangerous, after that we are going to identify in the card which is the primary and which is the secondary, since we know that the next thing is to cut the card with a cutting tool and keep the primary, with a few simple modifications we are going to make a homemade tool for the electronics workshop that will be very useful to us, then we are going to arrange it on a board and we are going to put some test leads from a digital multimeter that are recycled, at the end we are going to do some tests to see how it works and I will also show you the diagram so you can make the connections easily if you like the video do not forget to leave your LIKE thanks.
