I had a different type of scare tonight.
I had left my BB on my desk.
Came back ten minutes later to a smell of burning juice/burnt cotton. I looked over and saw that the entire tank of the Orbit was drained dry (hot juice had dripped all over the place), and I could see that the coil was visibly glowing red hot through the top of the DT.
The body and G10 panels of the Billet Box (authentic DNA 60) were hot to touch and the battery was only just cool enough for me to take it out and place it outside.
The DNA 60 had auto-fired and the Orbit was just at the point of dry burning. No juice left. You can see in the photos that the cotton had burnt dry. The plastic tank of the orbit would have melted next and maybe the 18650 gone into thermal overrun.

I reckon a few minutes later and there would have been a fire in my house. The device was standing upright on a cloth mat on a timber desk.
I fully disassembled the BB and cleaned all parts and contacts but I'm not sure I trust that particular device anymore. I'd always thought that DNA 60s had a 15 or 20 second cutoff but either that's not correct or this is a faulty board (as opposed to a bad switch/contact). Because it's a BBV product, I can't access the DNA chipset via escribe to check it out.
I wonder if
@BillW50 or
@ShamrockPat might have any thoughts about DNA 60 boards auto firing.
