@LordOfTheVapes cheers - good to know people are enjoying the read - ill try and put a new post up as its pretty simple to make and i suspect a lot of people on here have a load of old lipo batteries they need to figure out which ones to replace.
20mm tubes arrived earlier and the next wave of...
Well while testing the terpcicle and element heater i carried on with a little side project to test lipo batteries - i have a few collected over the years and some have less life in than others - in order to power the element with batteries i wanted to pair up the ones which matched the best as...
Yea its a pretty tight fit and also if you rest it on the bottom of the tube you can kind of seal it so just by rocking it back and forth you can adjust airflow. Been testing it most of the morning and for me is much tastier when there is more glass contact and so more conduction and a stronger...
Yea i was worried about that as well - i will see what happens when i heat a test tube and if a hot terpcicle fits or not - i think quartz expands less than glass so may be ok.
Ok minor annoyance the coil moves a little bit around the outer Terpcicle tube - you need to adjust it every now and then and rearrange the coils so they are spaced out evenly.
However the outer Terpcicle tube fits perfectly into a 24mm test tube with like almost no gap between them - im not...
Whoo my Terpcicle arrived and i got to work with making an element for it earlier today
I am using a 3mm x 0.02 nichrome wire and its resistance is around 1 ohm and im limiting the power it can draw to 120w - more info on the pid controller and element stuff on the other thread...
@LordOfTheVapes - i literally ordered one of the Terpcicles last night as i want to try out my little pid thing with a purpose made all glass vape so hopefully by mid week i should have something up and running.
Btw to load the straw try just sucking up the herb
I think i may have used one of their desktops as some point - with a whip type thing - was ok but didnt stand out as a unit for me.
Their portables do look nice but at the moment nothing has come close to the pure glass flavour im getting from my current setup with the tubes.
I havent used any...
I was/am very disappointed with the mighty+ - i had to get my tm2 repaired/replaced after hitting it too hard/often with a water thing in beast mode and it just couldnt handle it so rarely take it past about 7 or 8 now.
But the mighty+ is just so slow to get to temp and i just hate all the...
Yes im finding it hard to get spot on - its very sensitive - if i put a cold glass straw in it reacts slightly differently to a hot one
I have decided to tune it without any straw in and is ok when i then add the straw but seems to settle a degree under the setpoint until the straw gets hot...
Well i have spent most of the day tuning the PID - i was a bit confused as to why the temps were fluctuating so much like +-5 from the setpoint and was sure it should be better - initially i had just used the defaults for the PID so basically just the P part was actually being used.
So after a...
Have made a fully wrapped version of the small tube - can only run it at 80% and its pushing just under 125w at that limit so would be over 150w if i let it rip.
Its much better having more of the tube wrapped - i think more conduction happening with the thinner tube and more of the stem...
Yes its a smaller mosfet than yours and is ok with the 1.3 Ohm 2mm element, it uses just over 100W at a bit under 10 amps with the 12v supply. The mosfet doesnt get hot maybe a bit warm (40C or so) for the first 30 secs while it gets to the setpoint. I suppose any build needing more than 10...
Nope at the moment its just getting 12v from the power supply but i have limited the pwm to a max duty cycle of 50% to keep it at about 100w - at 30% the mosfet is not getting too hot and heats up in under 20 secs.
Im not too surprised its getting hot as its only rated to 15A continuous current...
Im bak and made a new version with the 4mm nichrome ribbon around a 14mm tube at about 0.4 ohms.
Also the ptfe arrived and works well under the nichrome.
Its rather rapid even when max_duty_cycle_percent is limited to 50% it pulls over 110W with the 12v adaptor and hits 200C in under 10...
From my tests with stainless steel 316 the induction coil struggled with it - tbh the element heater for this is the way to go but for other heating needs the controller will still work with induction pretty well
