    Help with Amica WiFi board circuit

    Google it didnt work. That's why I posted here. But its OK, I already solved the problem.

    Help with Amica WiFi board circuit

    I don't know what its ment to be. That's why I ask does anyone know a anything about this circuit? And about the Amica WiFi module (NodeMCU) as I can't find a valid data sheet.

    Help with Amica WiFi board circuit

    Good day! On this circuit can someone bring a little clarity, because searching in google does not help. I have an Amica WiFi board that needs 3.3v to run and a voltage level shifter. They are both made in KiCad, but on the circuit for the shifter it has 1npn and 1pnp transistor, but the name...

    Current control and defence

    It's a lead acid battery, the rest I do not know. It will be charged with 2A, 14.4V. There is a transformator coil connected to the thyristor anode.

    Current control and defence

    It should not discharge it as long is there is charging current from the thyristor, the idea is that the transistor should take away part of the current and thus regulate it as long is there is something to power the transistor base, like I said I do not know if it will work, maybe I should put...

    Current control and defence

    Everything else except the transistor works perfect. Yes the transistor short circuits the battery so it may reduce the current. The input is AC but since we have a thyristor and the diodes, at the kathode of the thyristor we have DC voltage. According to proteus it works, but still I am not so...

    I am certain I uploaded it but no matter! Later I will upload another one that I made by myself.. [mod edited to place image into the thread]

    Current control and defence

    Good day! I am trying to make a current limiting part for a schematic for charging lead batteries for automobiles. I use this popular schematic on the net, normally I would use a microcontroller to control the thyristor but I have here one transistor in order to limit the current through the...
