i agree with your analysis vis a vis thermal mass being slow to respond. i think the problem with desktops is not enough current - i like having minimum 3 amps - then the heater doesn't sag with a draw. my nichrome80 heater is 0.3 ohms, so at 6v is drawing 20 amps, but at about 30% duty cycle...

climbing trees is fine, i guess ... just don't fall on a shoulder and sever 3 rotator cuff tendons and detach the bicep, like spouse did 4 months ago - she got sutured last wednesday and going through recovery now for the next 8 to 10 weeks. getting old is not for the weak.

i'm like @gordontreeman - when i tried getting high before aerobics (NordicTrack) the clock stops moving. my ritual is exercise first thing in the morning with a calorie deficit, but with ~20 oz of water. these days i start with 5 sets of 20 pushups and 3 sets of 30 body weight squats, with...

that makes sense. and that brightens my day! 'rona got me seeing dark clouds everywhere. i guess the name "Herbal Cube" is appropriate after all.

doesn't that "and the substances themselves" mean the herb that the liquid or oil is derived from???

i am kind of amazed by how perfectly timed this shipping ban is for my own efforts ... i know, poor me ... after i finally get production figured out it will be impossible to ship. i get it, tobacco bad, but so is sugar. where is the sugar ban? the problem with mislabeling the vape product...

Well, well, well – another February. End of January 2020, i was poised to start my February project with 20 of the brand new pcb design. Then i got distracted for most of the ensuing year by biochemistry and a little botany. There were a few points of progress during the year – such as...

i call mine The Herbal Cube ... i wonder if that will fly? however i don't mind supporting the retail shop. this law pisses me off ... just as i am trying to go into more than one-off production this shit goes down.

the Eterra certainly inspired my interest in vaporizing cannabis. i was lucky to stumble across his website sometime in 2000 (i think). i didn't even know at the time that vaporizing was a thing. i think he got the idea from the pyrolysis plant in Bawlmer. R.I.P. Bob - you are remembered and...

@b0vver - have you had a coronary artery calcium CT scan? that artery is called the Widow Maker, when it gets clogged with calcium buildup. Scan takes about 15 seconds, no contrast, low cost in US @ $110. there is a widow maker video on YouTube. low carb, healthy fat nutrition, real whole...

been there, done that - what @KeroZen says is true - even 3A is enough to damage a switch or potentiometer. MOSFET for the win!

i was being facetious with my THC/anti-cancer comment. i did not mean to be disrespectful. however, i do take THC as RSO (Rick Simpson Oil) for melanoma and squamous cell carcinoma, as needed. i don't feel a need to backup my opinion about vaping weed for 20+ years not being harmful.

yes, since it is only about me, it is anecdotal. just not an experiment i am interested in doing. i have a lifestyle and a performance standard, as long as i meet my performance standard, there is no need to change my lifestyle. besides, THC is anti-cancer, everybody know that!

theoretical heart rate = 220 - age in my case, age = almost 73, or 147 beats per minute, and i maintain 105 beats per minute for 30 minutes. since i am just an anecdote, your proposition does not provide useful data.

weed doesn't seem to affect my heart. i usually hit 105% of theoretical max heart rate doing my aerobics. could be my all glass, temperature controlled vape, or eating right and exercising regularly. but what do i know? the problem with studies, imho, is the epidemiology of the group - they...

well, i finally tamed my monkey mind enough this weekend to finish refining my GCODE generator ... really hard to pull away from studying biochem about covid and the immune system, but i did it at least for a few hours. so the big effort was to develop and test the GCODE to mill the bezel for...

sucks about the shipping charge - that's why i looked for USA stock. i looked at a smaller Sainsmart but i need a 70mm Z clearance for my 2" cube with rough finish. and i have a spare Surface 3 which works well - touch screen control like commercial rigs. finished my Excel VB GCODE generator...

found it on AliExpress, but was located in USA, free shipping from CA - i didn't want to wait for a slow boat from Chin-ah. the link i have doesn't bring up the product page anymore - here is the store page: RATTMMOTOR CNC- POWACE Store - Amazing prodcuts with exclusive discounts on AliExpress...

i know exactly what you mean. mine is already 12"x16"x2.5" - think i will just duplicate this one for more production volume. been playing with mine for the last 3 days. still amazed at the precision for a cheap machine ($600 + USB to LPT controller)

well, that's a problem as we roll into 2021, what with the new law prohibiting sale of vaporizers - or rather, regulating them out of existence for the small maker (me). looks like it will have to be purchased from a retailer. if and when. after a december sales rush in my real world business...
