    Closed: Re: Constant 12V to momentary

    It is called 'Bluetooth 4.0 12V Proximity Switch Sensor Module' I found it on ebay, it operates with 12V, and it has a single relay, there is a NC and NO state, and a common feed(which I use with...

    Closed: Constant 12V to momentary

    Hey!

    I'm building a bluetooth proximity garage door opener.
    I've got a bluetooth relay modul which has a NO and NC state, once the bluetooth connects the relay closes, however it provides...

    Hello guys!

    After several hours of searching I've decided to ask the community about something I'd really like to find out.
    I've disassembled a small electric box (ccfl inverter) to fix some...

    Closed: possible proximity sensor or switch

    Hey guys!

    I'm trying to start a new project which involves a proximity sensor but I'm dont really have a clue how to start.
    My idea basicly is, theres a small key like thing in my pocket, and...
  7. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    I was once told to use a 555 timer but since i never really learned electronics(apart from the very basics which are required for a car mechanic) I dumped the idea when I saw how complicated the 555...
  8. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    Bias resistor as in resistor that is before the transistor? Im gonna play with the simulation hopefully the physical one will be as good as it :D Also one more question, if I dont use a transistor...

    I've tried recreating the same simulation with the same values and also adding my bulb to the relay. It doesnt seem to work, the coil is always energized

    Would you please help me out with my mistakes? I'm really not familiar with transistors yet :/
  11. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    I've put together the circuit, but the transistor is smoking as hell... what am I doing wrong?

  12. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    Actually I misread, its 600mA :D It'll be still okay I guess...I'm gonna play around with different capacitors.

    Still I dont understand the connection after the transistor on this picture of...
  13. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    Im using a 12v relay OMRON G5SB-1 12VDC, according to its datasheet it needs 33mA, so i suppose the 2n2222 will work with this and without any resistors? (The 12v comes from the vehicle light so its...
  14. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    One more question, what kind of transisto should I use? What kind did you use in your simulation? and also I see that the relay coil has no ground, or I'm just seeing it wrong?
  15. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    You guys are the best! Thank you very much for your help, once my project is up and running, Ill post result and you guys will be credited for your help!
  16. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    Very nice, can you tell me what capacitor and resistors did you use? The relay only needs to be open for a second, also thank you very much for your dedication!
  17. Closed: Re: Need help with a circuit! Proper coordination of bulb, relay, regulator

    Thank you very much for your advice, I will try it! Will post results after testing the circuit! Thanks again :)
