Dammit OF! I've been debating how best to get the Themocouple into the oven (screen would be ideal if I could somehow drill additional holes to compensate for restricted airflow).
Yeah... the depths of your experiments were about a hundred-fold of what I was thinking about. Nicely done, good sir!
Wow, thank you very much. It's really nothing special, I got paid good money to mess with this sort of stuff for a lot of years, nice to use it again.
I am intrigued by the VapeXhale Cloud EVO Perpetual Heat System that maintains precise electronic temperature stability while vaping.
The technology is here now which takes the guesswork out of gauging temperature, as well as dramatically improves overall cook efficiency and vapor quality.
Never seen a Cloud. But the technology has really be around a long time. Past the simple 'on/off thermostat systems (which aren't really that simple, even your home thermostat uses a gimmick called 'an anticipater' to artificially increase the thermostat housing temperature a bit as the furnace fire is on so the stored heat in the body of the firebox won't overshoot the temperature target....it shuts the fire off early), you have the PID controllers like are used to roast coffee on an industrial scale. Your car cruse control is another example of a PID system. Here you get proportional output (not just on/off but levels like the gas pedal in the car) control, the P part. Then you integrate the error (the longer you go too slow the more extra gas is added), the I part. Finally you differentiate the error so you don't overshoot and 'hunt' for the right speed. The D part, sometimes called 'resets' IIRC.
Like all closed loop systems PID runs on error. You'll get two different speeds up hill and down, one above, one below the "setpoint" with PID guys call the target value. Hopefully this error is small and repeatable.
If can do it on a sixties Caddy with valves, hoses and dashpots (did you know the first computers were
analog not digital and ran on
air pressure or other 'working fluid'?), you can more easily do it with electronics these days of course. But the systems are older than you or I. It's just a matter of is there a benefit to match the price?
I don't think it's needed in vapes. I think we've been lead to believe temperature is different than it is. My Solo experiment read 30 degrees higher than specified, but changed about 30 degrees depending on draw. Temperature control within a dozen or so degrees is probably plenty good. I just don't think vapes are half as precise as the salesmen say.......go figure.
Could easily be wrong, often am.....
That test was a bust! My probe doesn't read accurately unless what your trying to take the temp of is actually touching the probe. It was reading the ambient air temp in the bowl I believe. Which was about 120-140 degrees cooler than what the LCD screen said.
How about loading the bowl with ABV?
I think you've got a heat flow problem, the metal is pulling heat up and away too fast for it to be replaced so it reads low. This is one of the reasons you use tiny wires in the TC uses like I did.
