Been testing watts mode - it works very well without the inner liner and with the 16mm outer diameter straws.
When using in pid mode without the inner liner the pid struggles as the temperature drops dramatically as the cooler air flows over the thermocouple but then rockets up when you stop...
@Cheebsy im very happy its working for so well for you :)
Already taken care of better intake at the bottom of the outer heater - this can be adjusted with a flat piece of ptfe with a hole in it to allow the nicrome to go through it so seal it up if not wanted - I know its not as isolated from...
I have had an aroma 3 for a few days and its fabulous - previously grinding has been a chore and now i relish the opportunity compared to a space case knock off or plastic s&b one.
Love the tactile, solid engineering heaviness - fits so nicely into the ritual for me with letting the vape get up...
Sorry not had a chance to do a how to but been doing some testing on the new 16mm stems, For scale there is a normal tm2 stem in the pic.
All pair very well with the 18mm j-hook with an o-ring. You can use them as an outer liner tube for smaller diameter tubes as well like with the inner...
I'll try to put up a few pics as a how to later this weekend but essentially the thermocouples come with an outer glass braid covering - inside that are the 2 wires again each one is inside a glass braid. With the outer braid cover they are just to thick to fit between the outer and inner...
I have been gifted some custom stems all work so well with the thin walled heater - better than the 12mm stems i had been using as the distance between the inner liner and stem is much closer.
They already need a proper clean - all are different and some work better with just a bud but others...
Been playing with more stems and different arrangements - at the moment enjoying some very free flowing more convention sessions without the inner liner but using the tm2 18mm water adaptor paired with an 18mm j-hook
Some more radical stem ideas on the way soon - hopefully in the next few...
I have found a new way to use it - a tiny might2 long stem - so its open at the bottom
Heat it up to about 200 and let the tm2 stem get a nice heat soak.
The 12mm stems just fit into the tm2 stem with almost no gap - so you get a massive long heater - basically twice the length of the outer...
I have been working something akin to a bakx/electronic vaponic

I dont have that many pics of every design layout i tried - most pics are on the 2 threads - i do have a draw full of previous versions as it has developed with different nichrome thickness, lengths and various tubes...
I was worried about the intake airhole when i first started messing about with test tubes and glass straws but found you just adjust how much you pack/tamp the inner straw affects airflow far more than any intake hole.
Also if your straw touches the bottom of your outer tube you can also adjust...
I have put together some ideas and figures for a DIY kit
List of what it would include:
RP2040 PCB + firmware installed
Screen
Rotary dial
Mosfet unit
Thermocouple lead with ptfe + kapton tape protection
Heater:
Outer quartz tube + nichrome coil
Inner quartz 1mm thick wall tube
Inner...
Well im still messing with it - it worked really well with 3 lipos but they got hot fast so stopped that experiment after the first try but the coil got really bright and the rod had a glow to it but even with the butane torch i find maybe 2 hits before a reheat.
The video is from the 120w...
