Hakko FX-951 Mod - FumeBuddy
« on: August 08, 2020, 01:38:21 pm »
It was suggested on another thread to make a new one on this specific subject.

It was a fun project and I had quite a few board runs to test a few things.

I think the only thing missing that I was hoping to get was somehow making it work with only 1 mechanical switch instead of two, but I couldn't wrap my brain around making that work. I didn't want to open up the hakko and start proping around to see how it was measuring the change in resistance either. Having the thing work "dumb" was very important, as if I just need to touch up a few pads I'll use the classic breath-hold method :)

But for longer assembly runs, it's nice to not have the noise of my fan all the time. I've used it with both a Hakko FA-430, but also more recently and importantly a 4" duct fan and some flexible ducts blowing out the window.  Especially in the winter, pouring heated hot air from my house to outside is not something I enjoy :)

One last thing on my todo list is to make the 3D printed housing adjustable somehow for the spring tension. I tried to copy the exact same position as the stock unit, but I've noticed if I have my iron/base near the edge of the desk with the wire hanging off, it's a lot more "pull" downwards then if I have it further back and all of the wire is resting on the desk. But generally speaking it works great for my needs! A fun project with reverse engineering, PCB, and mechanical (CAD) for the housing.
