i found this is also true for my heating element - 1/8" wide nichrome80 ribbon. i finally settled on a physical connection - sheet metal screw holds the end of the ribbon against a flat copper post. thermal expansion / contraction has not loosened it over several years.
i opted for a k-type...
i have my vape set to timeoff at 7.5 minutes from startup. roughly 1.5 minutes to get to temp and heat saturate, then 6 minutes of inhales. i like long-ish inhales. seems to work well. i need to do the math to figure out how much heat transfer from heater to incoming air vs air flow rate...
@Polarbearboy - 1968 is when i started tokin' also. thanksgiving break, sophomore year in college. i'm still a hippie (in my own mind) ... sit around naked most of the time, at least. spend the first half of the 1970s in california - it blew my mind.
anybody measure their heart rate while doing aerobics? i hit 167 toward the end of my 30 minute session today on the NordicTrack skier. theoretical max for a 53 year old ... i'm 76.
there is a theory of longevity that there are only so many heart beats and one can use them all up too soon. i...
what is the MOSFET gate voltage from the pwm? i can't tell if it is 3.3v or 4.5v from the description. should be eq or above 4.5v (for the one i use) or the source to drain resistance can skyrocket and burn it out. mine used to get wicked hot before i learned this.
it is fully integrated into VS Code, via github. i can use the sidebar chat and do the inline code chat.
i used to do #include under classic ASP, but that has been replaced under ASP.NET - seems to be a share problem but i can't prompt a solution to the problem.
just came across this recent O'Reilly article about LLM lessons. still reading but it looks pertinent.

i am trying to do too many things at once and getting pissed off that i can't get anything done. my...
the top AIs now have extensive coding capabilities - or so they say. it certainly helps with understanding visual studio code syntax and structure. it has been about 20 years since i was current with MS programming tools. this helps navigate the docs to teach me what i need to do. but i want...
interesting. i have an excel sheet(s) that generate and export GCODE as a text file. do you think the AI (do you use Copilot) could turn this into a web app?
i am kind of annoyed with the current "AI". i have been trying to get it to handle some of my use cases, but it seems to be throttled. only seems to support entertainment - videos, music, emails. i can't get it (Copilot) to look at my code base. i can shove one file at a time into the prompt...
nice post.
my vape may meet what you describe in 9). my herb vial is a confined space with the draw tube resting on top of the vial. i let the vial + bud heat soak for 90 seconds after reaching vape temp - my current setting is 420°F (215°C) so 2 minutes from start.
the center of the herb...
nothing new to share yet. i plan to take all my work into some maker space. i think i have some useful information to share.
couple of days ago i was vaping on the balcony and thought of a new way to fabricate the cube body. i realized that my cnc router makes it possible to revisit the...
that is my approach also. the temp in the vial is about 50°F below setpoint until the draw starts, then it is at setpoint within a few seconds.
spouse got a mighty recently and it goes +5/-2 as how it maintains the setpoint. not very well tuned, and pretty slow to reach setpoint from startup.
i had trouble tuning the PID also. i found that it was very sensitive to being over controlled with too much swing over/under setpoint. i tried to use an algorithm to calculate the duty cycle for the PWM but the PIC 12F683 has very primitive add/sub with no carry or borrow. so i resorted to a...
ok, my bad - 12v gate should be plenty - i think you're right it must be the current draw. my MOSFET (FDB8832) is rated for 30V, 80A and i think the 16agw cable limits the current below that.
