    Help needed PE/IR Sensor

    That might be sensitive to sun rays.....better to use a pir relay set for whatever, day and night or night only.

    how to limit surge current?

    Good luck....a 500w heater doesn't have any "inrush current"...it's 99% resistive. Sounds more like it (inverter) is overloaded plain and simple.

    Panasonic tv on timer

    Isn't that how ALL TV remotes work........turn off with remote, turn on with remote...??? Why the timer in the equation...??

    Why Does My iPhone Overheat and How Can I Resolve It?

    I'd say all have to do with how much battery power it is using....go from there. Do some tests without using social media.(leave it on the bench unused, just idling)

    HELP: Induction hob power supply fault (incorrect voltage to rectifier)

    Transformer won't output higher than design unless input is higher than design. I'd suggest you have a repair induced error ( wrong measuring )

    Looking for advice powering 100v CRT on US 120v AC

    That should normally be ok as far as your voltage is concerned. However, that transformer has a 100VA rating (Volt Amp) which means it's maximum output current would be 1 Amp @100V AC. Question is, what does your monitor draw..?? If more than 1 Amp, then you are out of luck. You could parrallel...

    Hi everyone My name is GODWIN and have been working on a simple light intensity control system using the attached circuit but both my res burns

    They appear to be correct as is........although not certain what the neon is doing. Op, show a photo of what you have in front of you. Good clear with details........

    Help me!

    Your problem appears to lie directly above in the photo where the terminal into AE has been blown away.

    Equivalent to O6N03LA N-type mosfet

    Are you aware there are commercial r/c units for as little as $8.00...???

    Connecting 6 push buttons with ESP32 with 1 common pin

    Adding to the above, looks to me like you are shorting out the 4n25 internal LED (ok...but) you have no current limit resistors. Likewise for the open collector unless you intend to use software pullups. All seems rather unnecessary....please supply a complete circuit diagram and the code. (no...

    Transistor limiting current

    Which is why I suggested using a P-channel mosfet high side switch.(simpler) You will still need to add circuitry/microcontroller whatever to control the switching point.

    Antique meter

    hehehehe.....and still no photo....... I have to wonder sometimes.

    Transistor limiting current

    well, if it's hard on/off, just look at " high side mosfet switching" or if you must " same same in transistors"

    Antique meter

    Yes, it's the button called "attach files"....:rolleyes:

    Transistor limiting current

    Suspect it's an SS8550...... Don't see how that would be adjusted except possibly hard off or on depending on whether sun was out or gone to bed. Look at microcontroller, light level and also high side switching either by transistor (or easier/better) by mosfet.

    whats is proper name for this , heat sensor? temperature thermostat?

    Typical air fryer schematic....thermal fuse at bottom. Also here..................

    What’s the name of this connector?

    Would it matter...??? Cabling not all that large. Op shows the male and female and what looks like a hacked job anyhow.

    Sounds like double dutch to me...............
