I will clarify,
The 5V switch was just to test the logic.
I cannot use it as the switch is dictated to me as 230V.
That is why I am changing it and that is why I cannot use the flyback to feed it.
So I ask, will it work or not?
What are the risks?
Thanks for the help

You are right, the previous schematic had a mistake.
This is the correct schematic.
As for powering the MCU, I do have a flyback converter directly from the AC mains to the 5V supply.
My only issue is to translate the AC pulse from the push button.
Will the new circuit work?
In open state...
Hi,
I am designing a system to control fan speeds.
The selection of the speeds will be done using an MCU that will select the correct output to the fan.
The selection is done by a single push button, each press changes the speed.
This logic is working using a push-button connected directly to...
The battery is connected to the MPPT output.
What you see is the MPPT input.
See attachment below for the complete circuit (not fully designed yet).
The question is what is better (if there is any difference) for the Zener.
Hi Guys,
I need to protect my circuit from reverse polarity.
The relevant part of the circuit if an MPPT charger for a battery.
The input is a solar panel.
The voltage of the panel is to high for the MOSFET so I need a Zener diode to reduce the voltage.
My question is how to connect the Zener...
Thanks Brian,
That was my thought as well.
What will happen if I put a larger value resistor?
Will it damage the amplifier?

Hi,
I have system for sampling signals from a car radio.
It is done by placing the sampling circuit in parallel to one of the speaker.
The system is working fine.
My problem is that when I need to run many tests and in different volume levels it is very inconvenient to work in the room with...
Thanks Brad,
Mostly I prefer to work with IC but building an AGC from scratch is also an option for me.
I do not need a pre-amp since the input to the mic port is not an actual microphone but a signal that is originating from a high power amplifier - that is actually the source of my problem...
Hi,
I have a project where I feed line level amplifier from a high gain amplifier.
The main problem that I have if with the gain difference so I introduced an attenuator which solved my problem when the high gain amplifier was at his peak volume but now I have a problem with the low level...
Thank you very much.
I will build it, test it and report the findings.
Probably will take me about a week until all the parts arrive
Thanks again,
Tome
Hi,
you can use TI webench https://www.ti.com/lsds/ti/analog/webench/overview.page?DCMP=analog_power_mr&HQS=webench-pr
It is an online tool to help design DC convertors, it has parts selection option and you can input the required parameters to narrow the selection.
It also shows a suggested...
