    Which transistor to switch power?

    Well regardless of your opinion or what you might or might not be used to , you cannot put the mokkers on any comment here. I've been trying to sort out just what it is you are trying to do and show the best way to go about it. If you need others to chime in with a similar opinion then so be...

    Anyone have any idea how I could fix the ~60ms transfer time of my UPS?

    Therein lies the problem. I'm sure if you shop around you will find an appropriate item to suit your needs, all-be-it requiring deep pockets.

    Regarding Battery charger IC

    Maybe it's similar to this.........in which case, plenty of smart r/c battery chargers will work. Some, say around $50 mark are "combination" style and not necessarily suited to LiFe and LiPo. More expensive units have these battery type as individual selections in the charger menu. HTRC are...

    Which transistor to switch power?

    Your 6V is feeding into a regulator via RAW, the regulator needs overhead to operate correctly, usually 1.5v. The usb is 5v and feeds to the Vcc. With a mosfet on the servo and having to provide some kind of limit to shut it down to stop overriding a certain position completely overrides the...

    Potentiometer Guidance

    Potentiometers are commonly only rated at 1/8 to 1/4w and not suitable. Anyhow, many computer fans require a pwm signal or similar to run. Should be heaps of info out on the web, try a google search for the make , model, type, number of wires that you have.

    Switch Identification

    Commonly known as a "bedlamp switch" in some places. DPDT due to being on a flex lead.

    Which transistor to switch power?

    6v will not be enough for the Nano regulator and too much (5V max) for the Vcc. Sounds like you need a gear motor with a limit switch at the end stop rather than a servo. Using the servo and it's positioning abiliity is obviously a wasted exercise. You could of course, rip the guts out of the...

    Ac Electric motor

    Could be like these ........ https://what-when-how.com/electric-motors/single-phase-induction-motors-electric-motor/ If you know where it came from originally or if there is a nameplate etc. that might help. It's really a bit like asking for a wheel for a car. As for the colours, that only...

    Which transistor to switch power?

    You really need to provide more information on what it is you are trying to do. Include any and all devices, power supplies , micros etc. etc. Servos do not need a position feedback to the micro as it is all taken care of within the servo itself. When you say "up to 5v," what is it exactly as...

    Which transistor to switch power?

    Normally servos are not "switched off" as they need power and a signal to hold position. Other than that, micro will drive a logic level mosfet via a resistor or two. Once again, you have to provide more info if you want any detailed answer.

    Which transistor to switch power?

    This is a start but you need to provide more info. A drawing of the circuit would determine what you are trying to do. For example, what is driving the switching element.?

    Light/outlet remote status indication

    The way it's written you would need a current detector/transmitter on each and every light and power outlet. Rather expensive I would have thought. It depends on just how your installation is set up and wired but in most, the garage/shed is remote from the house and fed via a sub-main from...

    Arduino Project for ACC box

    Simple enough debounce with minimal hardware (small capacitor) to get you going.

    Which microcontroller should I use for a project I'm working with?

    That will need quite a lot of different interface modules on top of plc unit. Micros can handle all that you mentioned and more than likely at a much less cost.

    Which microcontroller should I use for a project I'm working with?

    When you start writing your code for each operation you will have a better idea of memory size and speed requirements etc.

    Arduino Project for ACC box

    Show your code. By 9V I am assuming a smoke alarm battery.....bad move. As is driving a servo off the 5v regulator in the Arduino board. Code would be much easier for you with 2 buttons. It's normal to go to an Arduino forum for Arduino projects. However, the web is chocka-block full of examples...

    Having the numbers off the device certainly helps. :)

    Lincoln electric pcb

    Looks like a varistor of some type and the FRA device seems to be a relay. No chance of a wider shot with higher resolution..?? Normally not a lot of device detail on the board but never know. Sure there are not still some markings on the varistor...?
