[Personal Project With Lights & Settings]

There's some small help there. Thanks. I say "small" is because due to my no-technical-knowledge background, I would only progress if given more detailed information. But I guess this is what I get for free advice. Thanks very much for your time. You're very kind to dedicate some time of yours to give advises to total strangers like me. Hopefully should I need further info, you're still here to help. Thanks.

It's actually reServe energy, because normally when you "tab" on a light switch, you would see the light illuminate for as long as you "poke" (press for 1 sec, and you'll see 1 sec of light). But I need it to flash for 4 secs with just 1 sec of poking the switch.

[Personal Project With Lights & Settings]

Hi, I’m currently onto some small personal project of mine that I thought of just messing around with but don’t have the knowledge, so I’m hoping that I would get some help here with it.
I have a non-toggle switch (like a lighter, you need to press and hold for a continuous flow of flame) that connects to a strip of LED (no flashing), run by 12V battery.
Now, I want to modify it that if I press and hold ON onto the switch for more than 7 seconds, it will start flashing at 1Hz. The flashing will only stop if I let go of the switch, but shall immediately “reset” into normal again. (will not flash unless until 7 seconds again)
Now a tricky one;
Another set (I have a non-toggle switch (like a lighter, you need to press and hold for a continuous flow of flame) that connects to a strip of LED (no flashing), run by 12V battery.)
Now, I want this set to flash at 4Hz for 4 seconds once “Poke” ON onto the switch. I realise this is quite difficult as it also means there must be some “reserve” energy for this to happen. I just have to “Poke” or “Tab” the switch and it will flash for 4 seconds.
Can anyone help me with this, please?

[From Battery Operated to Electrical Point Operated]

Hi, I know this is possible but I need some assistance in knowing what parts do I need and how to do it, this one should be very easy for most of you.

I plan to buy a fake (flame-less) candle using LEDs that runs on 4 AA batteries and convert it to running from an electrical plug point of 240V. By doing this, I avoid recharging the batteries every other time, as I plan to leave it on all the time.

How do I do it?

Thanks.
