DC Gen 2 Dry Herb Heater - under $40 and is amazing value

Check out page 2 of this thread for thermocouple measurement and induction heating issues: https://fuckcombustion.com/threads/bakx-heating-principle-inspired-desktop-vape.54964/page-2 I have had a little dig into IR measurement but it didnt fit my needs.

Dam it got a lot done added some code to automatically adjust the max duty cycle based on the live input volt/battery reading and so limit to a set maximum watt but update as the battery sags - or if using a car battery and someone starts the car causing a voltage rise. Well it could until i...

Ah true - i forgot all about it tbh - the wall is so thin there is little lag too - thats something i find there is a difference between 1mm to 1.5mm wall inner tube and/or stems

i think the outer tube really helps concentrate the heat back in from the other side of the ribbon compared to the bare element around the simple tube were it just floats away

Ah the main thick outer heater tube and inner liner tube? - there is basically just enough room to fit the nichrome and thermocouple cable

I am not clear which gap you are referring to When using with the inner liner there is a gap between the stem and inner liner tube - this depends on the the inner liner wall tickness - at the moment i have been using 1mm quartz ones and also the 1.5mm glass test tubes - i plan to get 1.5mm...

thanks - nice to know people are reading my ramblings with 3 batteries and no limit after about 30 secs yes they start to glow but not like a toaster - but it gets up to temp so quickly with 3 batteries that its quite easy to prevent it - just fire for a few secs and give the heat a chance to...

Been messing more without the inner liner and with 3 batteries its pretty amazing - so fast like you put the stem in hit the button while inhaling and before you have filled you lungs its vaping away. You cant over power it like other convection vapes - really there is no chance - if you keep...

My first cockup with it - i was using it with the tm2 water adaptor so no inner tube liner - the bong i have suffers bad blow back so when you stop pulling the water bounces back up the tube the stem sits on to - so causes a reverse air blow and weed pushed out the stem. Not good against very...

Dont we all like to max out a new toy and see what it can really do? So made myself a double mosfet - was a bit of a pain to make but runs cool And plugged in the 3 battery box and took off the pwm limit so somewhere north of 200W A bit of overshoot as i havent tuned the pid settings I...

The PID Ok its not very elegant but is a portable all in one (currently pico powered by a usb battery but can use a dc->dc convertor so use same power source as the coil) PID not tuned but no limit on the duty cycle so at the start its pushing over 100W with the two lipos - as you can see...

Wired up the MOD Have had a play with it and tcr mode with a material file from Steam Engine for it: "Temperature (degF)","Electrical Resistivity" -40.0000,0.9934246575 68.0000,1.0000000000 122.0000,1.0032876712 212.0000,1.0087567568 302.0000,1.0141621622 392.0000,1.0195675676...

Just been testing with the long tiny mighty dimpled straw - with 3 batteries and the raw swtich Blows a tm2 out of the water performance wise as a convection vape - its not a fair comparison with the 3 batteries but i have never been overly happy with that stem and the tm2 but this gives it a...

Yes your spot on the pid control is converging with this but at the moment not quite yet. The 3 control plains are: The RAW: Big button - just a momentary push button switch - rated for about 10 amps but am sure im pushing more through when i use the 3 battery box - the coil starts to glow...
