    big ear, fm transmitter.

    :)well ive just completed my second big ear circuit . from my talking electronics magaqzine , and now ill post it for all to share . but first ill exsplain. it as best as i can . this is an fm transmitter type with the electret microphone of which is housed in a dish, originally, its a speaker...

    Problems with headphones... static?

    allso be aware that if you get the same static effect if you have the volume controll on your head phones ,that you can allso use crc to clean the dust out of the potentiometer on those headphones , to clean out that dust that makes the static like crackling niose , every time you rotate the...

    random select

    :)leds to flash one after another youll have light chasser and by shorting the electro by taping to each side of that electro with 2 wires and runing it to a push button then you can stop the leds in there tracks, you can add numbers to every led and use it to pick your lotto to . if this is...

    high voltage photo flash capacitor charger

    :)audio guru ive added a few more wires to the relay coil and tried another test this time useing the relay to switch on an led via the resister and when i push the button the relay switches on the led for the set time then turns off like its suposed to go and i remeasured the voltage and...

    high voltage photo flash capacitor charger

    :)audio guru i disconected the 2 input wires to the relay and get the same votage as the battery supply when i measured it , is there something not right here i measured the only input to the regulater correctly and i dident have the relay contacts hooked up when i did it , the relay still...

    high voltage photo flash capacitor charger

    audio guru i fed the relay circuit 12.58 volts left in a 12 volts lead acid cell battery and measured the voltage at the relay it was the same

    high voltage photo flash capacitor charger

    audio guru your a genious anyhow i couldent figure out at first why the relay still worked and the open contacts close ok untill i ran one wire to it the postiive to be closed to switch on the driver circuit when the other negative input ran directly to the neg in of driver circuit , the timer...

    high voltage photo flash capacitor charger

    :)audio guru i was lucky to be able to get these details as follows without inturuption, the relay coil resistance is 40.4 ohms, the supply voltage to the timer with the test battery was 9.83 volts but its the same as the battery voltage and i dident realize it was low in voltage , now the...

    high voltage photo flash capacitor charger

    audio guru i apologise for the lack of information i was in a war with my partner yesterday and some other times and ive been so distracted that i just let my electronics idle for a few days till i know that i was gona get some uninterupted peace , hang in there audio guru ill get to these

    high voltage photo flash capacitor charger

    ive got a 10uf electro already in that circuit ,so do i still add the electro and ceramic in parralell from supply to ground still and i forgot to mention i have a 1n4004 diode across the relay inputs for protection is that nessisary when i got the 2 x 1n4148 diodes , and should i replace the...

    Transformer ratings?

    :)audio guru how about telling me how you get these words move across the screen like you did before when you replied to another topic and you got these smilies doing the same thing, id really like to lern that, this may be the begining of a new trend.
