    12V - 350V 200mA converter for motorcycle CDI

    We have an answer, but you must start from the beginning we can guide you in circuit modification, but you must be able to solder and solder components or build upon existing off the shelf products. Regards-Delta Prime

    HAM radio operation

    Not true! In the United States of America you can operate a ham radio in the event of a emergency declaration,even without a license, as FCC rules prioritize, ”safety of life & property“ over strict licensing.:cool:

    You put the cart before the horse! Guitar “pick ups”voltage level outputs specifications can vary from peak to peak, peak and RMS values. Vintage one coils approximately 175 to 520mV RMS. Active pickups can be 1 volt RMS or higher when you start ripping on it or strum it hard. What is the...

    Short range cat detector

    That’s horrible. That would pull the skin off the poor kitty cats paws. A simple circuit you can build upon. The (SPST) single pole single throw switch can be replaced a simple, infrared detector and emitter...

    Electronics-lab?

    It is the sign of the times now. people using AI and passing it off as their own academic knowledge and or experience in the field; although the intention is admirable to help others. They also spread misinformation across various scientific disciplines not only here on this site, but others as...

    Short range cat detector

    I’ve done it before, for my girlfriend‘s cat’s three of them I used double-sided tape. while in the vicinity observing to help the little critters once they get wrapped up with tape to un-stick them.The cats jump on the counter once maybe twice but never a third time. I even tried it with...

    Effective Star Ground for Linear PSU

    One very good simple option would be a classic crowbar circuit, stated before in a different thread by a well respected member of this community @danadak https://www.electronics-lab.com/forums/threads/small-circuit-design.312935/post-1922913 https://www.electronicshub.org/crowbar-circuit/

    Effective Star Ground for Linear PSU

    Almost forgot; have you ever worked with AC your local power utilities Mains before? I ask for safety reasons… your schematic shows no step down power transformer,fuse, filters,or support circuitry before your full wave bridged rectifier

    Effective Star Ground for Linear PSU

    As it stands for your application you are using the(K.I.S.S) method, Keep It Simple Stupid. This is not a derogatory comment towards you.Not meant to be insulting. Is used in electronics industry when designing electronic circuits. it comes down to money &,time go with what you have you’ll be...

    Effective Star Ground for Linear PSU

    It is not good engineering practice to rely on thermal shut down of your regulator for protecting your output power transistor, in the event of a short circuit, you’re transistor will experience max smoke.

    Effective Star Ground for Linear PSU

    Marshall, your thoughts. Re-ask your question please. I do not understand.. The LM317 does generate some noise itself I would never even consider it for high fidelity audio synthesizer power supplies But in your case you’re all right. For large voltage differentials between input & output &...
