Not really done much recently other than tuning the PID for the 3mm nichrome and 20mm tube and lots of testing :) - the git repo has been updated with the pin, tuning and heater settings to the top of main.py to make things simpler to setup and more in one place. I did look at nozzle end for...

Have a read of the below article as i found it explains D very well. https://www.controleng.com/articles/understanding-derivative-in-pid-control/ Out of interest what PID controller are you using? Your build is looking great.

I think this affects the taste so much - as it cools past a certain point the taste drops off maybe i need to trim the 10mm ID one down and test it more but not sure my jars can take it as when full is about 0.5g I know what you mean about the different temp feel and the joint like experience -...

Yea i was thinking the same thing - some 2mm wall tubes with the bottom some how sealed For me not sure there is much point going greater than the 20mm diameter the 24mm or 30mm test tubes are way to big - im thinking the 18 worked better for the thinner stems but the 20mm seems to have a bit...

Some how i have managed to break a few of the tubes - the bottom got broken on 2 of them - i think the handle was set too low and when putting down/into the glass jar i must had hit to bottom harder than i thought. So have adjusted the handle so it hits the lip of the jar before the tube hits...

Finally put together a little box as i was getting annoyed with the breadboard version with wires getting loose and needed the usb tether to the computer for power. It really is fairly simple just a plastic box everything fits into and also a LM2596 step-down dc buck convertor set at 12v ->...

Yes you do get some condensation but the longer it remains as a vapour the nicer the taste i think. Your chamber for weed is quite short and im sure having the yellow balls heated will help keep the temperature up and flavours for longer - Im using a very long chamber for the weed like up to...

@CaleidosCope looks nice and neat - whats the ID of your stem? I have been temped with adding some cooling balls or similar to the larger stem - i think that in order for certain terpenes flavours to be taste-able they need to be past a certain temperature and in a vaporised state and not...

Does the thermocouple in the tube help? - yes i think it does it gives a pretty good reading of the air in the tubes temperature - it also solves the issue of the pid keeping the element temperature stable but the tube getting hotter and hotter over time and keeps the tube temperature more...

I have been using occasionally like that for a while like since i got it around xmas - works well but for smaller loads i have been using an all glass home made thing more recently.

Just having my first few thin straws in the new setup now. Its much more sensitive temperature reading wise and notices the inhaling - just having a bit of play with the pid tunings as the coil is more powerful than i thought and have limited it to 80% and its pulling just over the power supply...

@Cheebsy - amazed i have lived so long without one Cheers for the tip to take off the edge have just blasted it with two decent butane torches and its smoothed it out nicely. I did all the drilling outside dribbling a bit of water on it while drilling/cutting - i didnt have a dust mask so will...

Wow i wish i had got a dremel earlier in the build. First go to drill a hole in a 20mm tube and all went so well that i didnt pull back fast enough and smashed the chuck into the tube and cracked it. Second attempt was perfect and a naked thermocouple fits just right and think some of the PTFE...

After about day of using the 20mm tube with the 4mm nichrome and its too powerful - the element is too far up the tube so most of the straw gets hot and has less cooling effect. Im not sure if the extra few mm diameter of the main tube is making much of a difference other than allowing the...

I have been working on a little pi pico based pid project https://fuckcombustion.com/threads/bakx-heating-principle-inspired-desktop-vape.54964/ and wanted to power it by some Molicel P28A lipo batteries I have. The problem is I have bought the batteries over the years and dont know which have...
