Alright, this has been a long time with no update. Who still has one of those around? If you do, there might be hope!
With my two samples, I was never satisfyed by the device smell. Even when cold and aired for months, it smelled a lot of things, but mostly plastic. The "reversed flow" mod I did on one of the devices was not really practical, and in the end both haven't seen any use since my last post.
With a friend we decided to do something about it, because it's really a shame! I had big hopes for this vape and it has potential really. The battery is insane (3S), the peak power output too (120W), the heat-up time is so fantastic it isn't far from "instant on" or "on demand vapor". I mean you could power it on, get a couple of hits, then press the button to put it in sleep mode, then resume later... The bowl is okay, at least it's ceramic. The OLED screen is badly driven but it's not ugly either... And last but not least it has rather precise active (feedback based) temperature control.
So here we go: I'm not starting a separate thread because it's really FM8 specific, and I hope it can prove useful to future reader and owners. This is the FM8 DIY mod adventure! Here is a first pic of the transformation process, showing what's left of the first device after complete dismantling:
We kept the bare essentials, everything else has been removed. A pen style vape is shown nearby for size comparison. As you can see the FM8 could have been considerably smaller if they didn't try to implement this convoluted vapor path. The PCB's are single sided, it's a very small micro controller (they removed the part number)
I will post more pictures of the process in the future. We already toyed with the vapor-path part using e-cig parts and keeping the original glass straw and the silicone ring around the bowl (not shown in picture) to isolate it from its new holder piece. A short test run was very pleasant albeit "ghetto style"... Stay tuned!
