How would one go about developing their own soldering iron?

How would one go about developing their own soldering iron, are there any example pcbs you could orient yourself by? should i just basically copy what the pinecil is but use a bigger mosfet?

Me and some friends want to develop and make a soldering "iron" which is just a usbc input and aixun handle output, with the electronics inbetween, so you could use up to 24v at 8a, this would of course require a bigger fet, but other than that, it shouldnt require much reimagining, other than adjusting the pcb layout and some of the code probably...

Hello. Not sure if this is the exact answer, but there was a pretty similar discussion relatively recently, so probably you could start here first.

P.S. I'm not a professional hardware electronics engineer, but in my humble opinion 8A is a total overkill. I use Pinecil V2 with a EPR/PPS power brick via PD3.1 240W supported USB-C cable, and 98W (28V * 3.5A, for long tips) and 126W (28V * 4.5A, for short tips) is more than enough, at least with pretty solid thermocontrol & stability provided by Pinecil V2.
