Tesla Invader 4X ... PCB Alternative

I somehow don't buy that SmokeyJoe, as you have way more vaping experience than I do ;)

What I can say about this modification is that outside of the obvious of bringing a dead mod back to life ... Should you have a mech, and want a little more flexibility and control whilst retaining that wonderful hard hit, then I'd highly recommend you look into building something like this into it :)
Bud, i vape, i dont work for NASA.
 
Herewith a revised / ver. 3 schematic ... Rather than toss a mod with a damaged PCB, build one of these ;)

I've added a power down feature to prevent damage to cells by discharging them below a preset-able limit as well as a reset-able fuse / PTC.

The diagram below shows two 555 timers, however I used a 556 Dual timer

This circuit could be used in a single cell mod, providing the zener diode is changed to from 3.3 to 2.1V and that a CMOS 556 or two CMOS 555's are used.

Sheer brilliance!

Thanks Resistance ... It's more like 'necessity being the mother of all invention', with my combined Scottish and Jewish heritage wanting to sweat the asset for maximum returns whilst having fun resurrecting the dead ;)

Anyway back your work, love it, one day I will send you a tube semi mech that somehow fires but does not put much power through compared to another of the same one.

It's an easy fix ... Replace the mosfet ... it's the only thing between your atty and the battery, else slap a dead cow on the braai and invite me over
