    .5 delay with a 555 timer

    Look on talkingelectronics web site...books and circuits galore....

    Then throw in a load of 120 ohm. On 12v = 100mA. On 24v = 200mA. :)

    Need help determining correct capacitor for small gear motor

    Bulging is normally associated with electrolytic capacitors not paper or poly caps as you have there. Only test which would confirm is a cap test out of circuit.

    Small Project to connect two dry contact sensors to one signal. Is it possible?

    One cannot willy nilly add extra circuitry to existing without knowing the possible effects. Start with supplying a circuit diagram of existing and then what you plan to add. Otherwise it's just a wild guess at best.

    Need help determining correct capacitor for small gear motor

    Nameplate says 20uf...you have 17.5uf...may not affect it that much but....who knows. Are you running the motor on 115v ac...? What are your wire connections, draw a diagram.

    I want to make a speed limiter for my motorcycle

    Wrong approach....check what most countries enforce for learners and those with less than 2 years riding experience. I can assure you it's not sticking a rev limiter on a Ducati. Here's the thing....I've heard all the excuses before and none are viable.

    I want to make a speed limiter for my motorcycle

    The whole idea of a rev limiter on any motorcycle used for everyday commuting is just plain ludcris. Rev limiters are used in situations where engine revs continually approach critical piston speed as in GrandPrix racing and the operator has their attention on near maximum performance for hours...

    I want to make a speed limiter for my motorcycle

    That's for you to work out as there are many ways depending on your motorcycle setup. Suffice to say there would be litterally thousands of Arduino projects out there on how to tap the rpm. Once you find one, you adapt the circuit and the sketch to suit your requirements. No one is going to do...

    I want to make a speed limiter for my motorcycle

    Well, if you cut the engine at certain rpm via the "simple method using ignition kill switch" .....you have all you need. That was my point all along.

    And now something weird

    Only if you limit to current know physics...consider black holes and then explain that. .......or Dr.Who's Tardis for that matter...‍

    Beware buying from china

    That may be true but....how would you know. Most clones (which work just fine) are either descriptively or via photo, unable to be verified one way or another. Simply paying a higher price would be zero verification that one was receiving a so called "quality" item. If you think some resellers...

    I want to make a speed limiter for my motorcycle

    All motorcycles have a kill switch...bridge that with a set of relay contacts.....not as though it has to switch in and out at high frequency. Simply add some amount of deadband so it doesn't cut in and out at some crazy rate. Have to ask again though, is this to minimise over rev of engine or...

    Is it necessary to power on in order to diagnose failure IC of CRT TV?

    Think you'll find somewhere that this is an English based language only. Irrelevant for me really as I already know how, point is, as I said, do you.

    Question about DC current flow

    What you need to be concerned about with lv is the voltage drop over the cable length and whether or not your connections are up to the job (also points of voltage drop).

    Do you know how to discharge the crt tube???? I'll wager not....

    Is it necessary to power on in order to diagnose failure IC of CRT TV?

    I'd advise since you know zero, throw it back in the bin and automatically extend your expected life span up to 10x.

    Identify this diode.

    Could have been from the dark side of the moon, how would you know. You made a statement to which I added reality.
