With charged batteries, as a next test, I loaded some straight kief. I didn't think to weigh it, I'm already used to the idea of filling to the top of the post. Very fluffy stuff, I was thinking I don't want to shake this up into the screen so I decided to run it a bit and open it up and look it over. I went to 330 again after not getting much action at 320 in a minute or two, the hits improved, no big clouds (I checked under good light), different taste, but it seemed very potent. Maybe 3 medium hits and I shut it off. My tolerance is up, but the effects were stronger than I'd expected right off. Neat stuff. So, as I'm still coming on, I open it up (with a handy rag, not the oven mitt again this time, SC, please forgive me but the best I could find was a pot holder....). Sure enough, the bulk is way down but some is still untouched in kind of a crust around the top which poked down when touched with a toothpick. Vapor came swirling up as the heater was still hot. I decided to top it up since it was now maybe half full.
Setting it aside, I went to get the vial of kief. I had no trouble seeing the big clouds coming out of it when I returned, SOB had done it to me again! It was running away on it's own! Did I ever feel stupid, still do. I wasn't through using it, I'd checked very carefully on shutdown. With some trouble got to 'off' and confirmed it. It went dark, didn't respond to 2 or 3 button presses (takes 5 to turn on or off). It was off. Except it wasn't. I turned my back for maybe a minute and it was smoking!! It came to life with 5 presses, gave me the 'on' prompt, which I confirmed and it lit up and displayed 424 degrees. I've never been above 350, it was set for 330 and reading about that when I shut it off....or so it said. At least this time the display was still cool enough to display. I now think the loose battery/reset problem from earlier is not what caused the problem before. It was probably more like this time (where it was evidently running away when I set it down) in that for whatever reason it left the heater on when it went to sleep? Perhaps it's just been overheated too much? Maybe there's a subtle program issue, I did have trouble getting to the 'off' prompt. Still the display was off, it was unresponsive to button presses, it seemed to think it was off?
You know this guy came from SC with a couple of warnings (past the oven mitt part....). One was to watch out for a dodgy center contact pin in the battery tube, the other to take the batteries out when I wasn't using it. I should have taken him at his word, and as more than a guideline. Even though he didn't have it run away (AFAIK), he knew what he was talking about here. Who'd have guessed? While it seems random (it's run fine several cycles, cooling off nicely before I break it down for storage and battery charging) it's only happened twice now and both lately. I'm leaning toward sick microprocessor.
The center contact issue seems to be straight mechanical. It can goof up the switches if it acts up I assume by pressing upward on them. Clearly an artifact of being a prototype, thus far we're working around it.
So that's the latest. It does seem to do a good job with kief (although I just lost half my stash on an aborted test....) and it's definitely not to be trusted unless you have it in one hand and the battery in the other. Although when it works, it's doing well. More testing is called for, with a very short leash.
