In today’s world of audio production—whether for music, podcasts, broadcasting, or live performances—digital audio mixers are the heart of the operation. These powerful tools allow sound engineers to balance, blend, and shape multiple audio signals. Analog mixers offer raw simplicity and tactile immediacy. Compared to them digital mixers provide versatility, automation, and a boatload of →

One of Finland’s most popular locks, the ILOQ C10S is a high end lock used by millions of people. IloQ lock system is a series of electro-mechanical lock developed in Finland. iLoq system is known from the design that uses electronic keys and locks that draw their power from the key when inserted inside the →

Still, Ai is not capable enough to create correct diagrams on its own. I wonder if it is posible to post working circuits to Facebook…… mostly only AI crap seems to be posted Example from https://www.facebook.com/share/p/16vJCdn37B/ The left side circuit is almost correct, but for example the control button has only one wire in it, →

I saw the following circuit design posted to Facebook. Source: https://www.facebook.com/share/p/1HuYVvXHcf/ What is wrong with this design: No isolation from mains, potentially electrocutes if you touch any part of exposed LED strip. The circuit will only give around 220V/30000ohms=0.00766.. mA current that can light one normal LED but not any long LED strip like shown →

I saw this at Facebook at https://www.facebook.com/share/p/1YitRKKmxy/ Can burn loudspeaker and transformer due DC flowing Dc quite probably saturates transformer core-> lots of distortion and very little sound Even if works the transformer is expensive and limits sound quality Very low impedance sound input is less than 30 ohms – which means this circuit does →

I saw this circuit at https://www.facebook.com/share/p/16HFEwzkcQ/ The diodes try to charge and discharge the mosfet gate based on static electricity of user touching. Depending on the amount of charge you happen have it might not work at all, might work or could fry the mosfet (they are static sensitive components). FETs are extremely vulnerable to →
