    Sir I hoppe you can answer my question I like to use hv ceramic capacitors with my hei ignition system series of capacitors soldered together and I place it any where on my e core ignition coil mostly coil + side the other side I ground to chassys or wia some trip switch .
    Now the problem acured my car is 80s Opel it has the Delco 12si alternator I think its A circuet alternatir I use only pin 1 with light bulb the other pin 2 isnt used I do not have any diodes in my car only bulb when ever I use those multipel 3 kw capacitors in seies my alternator starting charge gets displaced so my alternator constantly back feading true the bulb unless I give it more revs and the alternator starts charging my baterry and the alternator light goes off but If I run on normal idel speed the bulb turns on again .
    So can you tell my please what thoes capacitors have to do with the alternators voltage regulator amd how can I counter this strange effect?
    How much I culd understand inside my alternator regulator I found miniature ic chip and 2 small capacitors how much I culd understand the ic chip is also baterry negative voltage potential controled some sort of?
    So how to chuse capacitor or value to counter this effects?
    I have lot capacitirs resistors and 500k potenciometer also have insulated alternator voltage regulator screws but dont know how its calculated out come that my alternator charges in what rpm ranges.
    So I hoppe you understand my question .
    So Im not shure what to use honestly resistor/capacitor box ,cloosed loop voltage regulator Im still cinde of woried to over charge my baterry

On your video it is opposite, after turn power on or push the swich you have desired time delay for relay and green light turned on after that it turned off.

    Hi Robojax, is it possible to make a hack for battery-powered lamps?
    The timer module is not connected to the voltage. Only when the push button is pressed, the module is supplied with voltage via the relay and after the time, everything is disconnected again. So the lamp and the module do not need any power. Is that possible?

    I'd like to make a delayed start signal for a project but I can't wrap my brain around these timers offered on Amazon.
    I have an inverter (Schneider Electric XW+) that will use a battery bank to power my critical loads. It can also get power from a generator that it will start when told to do so.
    I want to connect a 12vDC relay to a power adapter connected to a grid outlet, that is, not a critical load outlet. When the power goes out the relay will switch and the normally open connection will close. That's the trigger that the grid power is out.
    That trigger needs to delay start the generator after grid is down for 15 minutes by momentarily closing a connection on the inverter. However if the grid comes back up before the 15 minutes then everything is canceled, that is, I don't want to signal the inverter to start the generator.
    Another delayed timer relay is to stop the generator after the grid is up for 15 minutes. If it comes up and then down again before the 15 minutes, then nothing happens. But if the grid stays up for 15 minutes, (12vDC relay connected to grid power adapter is on), then a different connection on the inverter is momentarily made signaling it to stop the generator and return to using grid power for the critical loads.
    Any thoughts, comments, ideas, etc. will be appreciated!
    Thank you

    It seems that there are two versions of this module. One that is ON and then it shuts OFF after timer and one that is OFF and turns ON after timer. On the first video you have second one and on this video you have first version. It's strange that there is second version since then relay is on all the time and you still have NC and NO open connections. Anway since this video i managed to rewire mine to put capacitor in place of potentiometer and potentimeter in place of capacitor.

      Robojax should pin your comments as the top comment. From what I've read in these comments you're the only viewer that understands how this chip works. Including Robojax. Sadly, it's buried down deep in replies. You're absolutely correct in your assessment of this board. The logic as it configured is ass backwards. I've worked with the 555 for over 49 years and have never seen one wired like this one. It's absurd to have a board that spends 60 seconds with the relay de-energized while the rest of the 24 hour day the relay is energized and the board is powered on! WTF? Surfing through the data sheets I think anyone would be hard pressed to find Rt tied to GND and Ct tied to Vcc! It's simply unorthodox and inefficient. My 555 project is intended for a self cleaning (60 sec) filter cleaning cycle for my shop vac. Note: For fast recovery (re -trigger) add a reversed biased Diode across 'Rt' timing resistor. It speeds up discharge of the timing cap 'Ct'.

    Sir
    Where is pin 7 connected?

      I don’t have the board , just look at it from both side and use multimeter to figure it out. Also look at 555 timer datasheet you easy read it.

      In this use of the NE555, pin 7 is not used. It is the discharge pin for a timing capacitor. In an astable multivibrator circuit it would be used to discharge the timing capacitor to continually repeat the charging cycle. In this case the NE555 is used to create a monostable multivibrator (Also called a "one-shot") so pin 7 is simply not connected to anything.
