    Can anybody out there help identify these diodes?

    For shame! This posted in homework help and you gave him the answer. You are now on double secret probation.congratulations. :p

    Hello there :) Diagnosis? I believe you know how this works already any and all information available to you must be conveyed to us. I dis-like playing phone tag. But if you insist. Is your problem with one of these units. Sony home theater, SR4W. Onkyo TX sr-308 Sony DZ640. Tag! you're turn...

    LED circuit contains caps, diodes, resistors, what's going on with this?

    We named the dog diode! Here's the entire data sheet. Good luck to you.

    LED circuit contains caps, diodes, resistors, what's going on with this?

    Hello there :)U1 TASI 5101-0002 is either SD 7501 or SD7502 controller if your DMM came with a peak hold and surge measurement you have a SD 7502 and you have to do your homework and find that one. This is why data sheets are so important they give you all the answers! This is just a single page...

    No! Don't know how you got that idea. Here you go buddy this is a good read

    Boost converter

    No! The cheapest and easiest way to solve your problem is connecting an NTC negative temperature coefficient resistor in series to limit the in Rush current You see the capacitors are the cause of the in Rush current without it wouldn't be a boost converter the capacitors charge from 0 volts to...

    Boost converter

    Your unit is working properly. What output load are you using? Did you wind your own inductor L2? The 33uH inductor that is L1, is the inductor which is responsible for the Buck mode of operation whereas the Inductor L2 is used for the Boost mode inductor. during the boost mode when the input...

    LED driver

    Quote from data sheet. "It uses patent pending source driver architecture and demagnetization sensing technology." I don't know...looks pretty bulletproof to me. Built-in 650 volt power mosfet LED short and open circuit protection CS resistor under short circuit protection. VCC under voltage...

    Curious?

    That is the point of these forums isn't it I mean that's the point I'm finding a lot of individuals almost use these forms as platform for their memoirs which is wonderful. Is that what happens when they add the word solved to a title of thread it becomes read only? That would stand a reason, no...

    Curious?

    So when you include the word "SOLVED" to the title of a thread, access is denied Shouldn't you erase the link as well. So boneheads like me won't ask these questions. :p https://maker.pro/forums/threads/running-project-on-lithium-battery-and-reading-constant-battery-voltage-adc.298628/

    Has anyone ever replaced a garage door opener that uses the old fashioned dip switch decoder with a raspberry pi? I need to use the old remotes.

    Siren circuit

    Your short circuit project is about to become very successful congratulations. (Just kidding) If you built the circuit can I take a peek. So let me get this straight you are adding discrete resistors onto an eight ohm speaker,correct?
