My totally impractical mod project

[Robert Wilcoxson]

This is the preliminary stages of my first mod. Power source is currently a 12v 2amp aftermarket surface wall wart. Has a mc34063 switching controller with external pfet. I have a pot to control the voltage and one to limit the current. It is just bread boarded now but with the 12v source I can adjust it from just over 3v to 10.5v and crank the current up until it runs out of juice or something pops.

Here's what I have so far if the image attaches.

I'd love to have a unit that I could just plug into the wall. Of course it would only be for use at home or office

I'm still waiting for some battery boxes and momentary on switches. I'll solder everything to a pcb after I do a bit more testing. Pretty sure if I heatsink the fet It'll be good for better than 10 amps at vape voltages though. I'm pretty happy with the current limiting pot though since I couldn't figure out how to do variable wattage.

I have parts coming to do like three of these and some chinese buck modules, voltage and amp displays. I figure I'll do
some battery powered and some I can run off of laptop power bricks for when I'm kicked back at home
