So I now have a 5 volt snus tin mod

[Israfil]

Just upgraded my snusbox (the one with magnets inside the cover to stick it to things) to 5 volts with a ptn04050 chip. One odd thing, with the cover on (the magnets are over the chip) it vibrates a little when I push the button. Kinda cool. Check it out!

I think I've locked down what the vibration is coming from. Apparently inside the chip is a coil (from what I can tell) that when energized is pulsing a magnetic field at the same rate that the chip pulses the electricity to jump the voltage to 5 volts. Kinda interesting really... It's like a tiny little pulsing electromagnet.

That... is AWESOME. And ironic.

The batteries just passed the point where the chip shuts off because the input voltage is too low. The vibration stopped. Who needs a low power LED eh?

Scraped off a few of the words on the warning label of the snus can when I made it.
Warning: This product is () a safe alternative to cigarettes. ^_^ I love the irony too.
