    Dumb Mistake with SIM900A Power – Using Diode Drop from 5V to Fix It, Will It Work?

    Hey guys, I'm working on a GSM project using the SIM900A module, and yeah I <Mod: Obsecenity deleted> I totally forgot that SIM900A needs max 4.5V on the VBAT pin. So I went ahead and designed my whole circuit thinking everything is 5V powered, including SIM900A. Luckily, I had already added a...

    Turbocharger Electronic Valve Control

    Hi, I have seen that the H bridge method is used to drive the valves required to use the turbocharger feature in the engines, why do they prefer this? There is no DC motor, they open and close an electromechanical pressure control valve at a certain rate? What could be the reason for doing this...
