    Not getting correct voltage from voltage regulator

    Lp2950 (ok ok, i've ordered one lol) Well i ordered 10 (3.3v ldo) ...

    Not getting correct voltage from voltage regulator

    The output cap should really be there to smooth out any ripple (which is important) but.... Any reg with a feedback should get a clean voltage reference (hence the cap) but say 78xx (not adj) without fb should be ok with a cap on the input and not much on it's output as the reference is to...

    Light Ignition Circuit?????

    Interesting little device.. first i've seen one, first thought it was some kind of triac/thyristor/diac in one

    Not getting correct voltage from voltage regulator

    Davenn.... My post was not saying you don't need them, what i am saying is, i would like to do some tests using a small resistive load (without the cap) Not for any other reason except to discover the results...

    Not getting correct voltage from voltage regulator

    I will have test this out with several regulators ... switching regs i understand why you need to place a cap across its output or to use an inductor . But linear regs should be happy with just a small load (i'll have to have a play sometime)

    Finding replacement for legacy Motorola Gate chip

    Hence my point, pin compatibility... ideally an embedded RFID chip so no pins are used could be an option?

    Not getting correct voltage from voltage regulator

    If it's a 7815 you need a load on the output, use a 1 - 10k between out and gnd (the load)

    Finding replacement for legacy Motorola Gate chip

    I'm amazed there's (yet) no way cloning logic chips... how it would work 1.. with some kind of jumper/dip, select your logic chip 2.. instruct the chip to be a logic chip via a command?

    Cannot get Breakout Module to work...

    unless you added circuitry to reset it just before flashing... you need to hit reset if thats the problem

    Walky Talky (Android sorry only)

    Take a look at "Craig's Walky Talky" Talk to family, colleagues for free over wifi, no internet needed just a wifi modem! New Feature.. it now has a floatable microphone which means you can work or play and voice chat, first app ever to offer this kind of functionality for multicasting your...

    I need to leave Australia!

    I thought i saved just the photo of the a4.... you can clearly see now (includes electrician "special class")

    I need to leave Australia!

    apart from 45c heat for days on end and then 3c in the winter , spiders, snakes that try to kill you, but still ok... no to medical cannabis... more serious punishment for animal activists who show conditions of animal welfare but anyway here's the latest this joke of a government has...

    Basic Toggle Switch Circuit

    a 2n2222 would do the job (about 3c)

    Basic Toggle Switch Circuit

    Well, any generic transistor... as i said tie gnd usb to gnd of the speaker, use a multimeter to find which side of the button is 5v and which is ground... but it requires a pulse, or it will switch on and off, a 555 sounds like a candidate

    sister? i'm more worried about my daughter who's 13 than a fake sister...

    Generator protection

    Then yes it's safe to do so lol...

    Generator protection

    i'm no electrician nor am i interested in being one... but it is safe if the cb's are flipped/off/, that's all i wanted to know lol

    Generator protection

    question... if all the circuit breakers are flipped, is it then 'safe' to power the home from an inverted plug (male part live from the gen plugged directly into the wall) ? Was wondering.....

    Basic Toggle Switch Circuit

    To confirm... non latching button? in that case there's a flipflop used to switch on the speakers, open it look at the non latching button, you'll be able to switch it on by simply shorting the button... the same can be done with a generic transistor
