So I managed to get her together last night. She's not 100% done , but she vapes.
Here's where I'm at right now.
I was originally going to have a mosfet for reverse battery protection and a master switch for a hard on/off but I decided to cut them when I was making it. Mostly just out of frustration and a want to have it be done with. Long story short it took me forever to solder the chip (embarrassing picture below lol) and the 510 took a while due to a small mistake I made that needed to be fixed.
Anyhow without the mosfet and master switch there's a bit of extra space for sure. Probably could have gone with the G instead if the B for the box.
I still need to mount the potentiometer as well as probably a voltage output meter when it shows up.
The one thing I certainly learned is that soldering tiny things is really hard and I'm terrible at it lol. It all works though.
