Hi, electronics is not my strong suit. That's why I'm asking for help here.
I need simple "power button", but so that it would switch power on only for one second. Preferably so that you couldn't hold it down to prolong connection. It should be simple, cheep and robust.
I need it for 18650 battery (4.25 V).
I had idea about electromagnet, some plastic tube with coil, trough which you throw iron pin. Like nail or something. To create magnetic feald, which would move simple switch and create connection. But that would need secondary power source, like 9V battery. And if I'm not wrong, magnetic feald would be created at ends of electromagnet, I need to place some metallic lever there, but I need it to be free from obstacles as well, to allow to get pin in there.
Might be you have simpler, or more elegant solution.
Thnx alot. ))
