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...

So MKII was too chunky but not sure if people noticed the deans connector at the bottom - that wasnt for charging but for other power options instead of the battery, On to MKIII Example setups Control options Power options Heater Example water use:

I made a start on a unit to hold it all together a few weeks ago but abandoned the build as it was too bulky and needed a rethink. MKII Inside Back/heater Not a complete waste of time as it did get me thinking of a better solution...

Nope i did have to get some help there but should be able to get more made. Its not simple anymore or glass! I do owe someone a vape though when other bits im scheming away with come together.

A little update - not so simple but sticking in this thread rather than a new one All quartz outer and inner heater liners The inner ones walls are 1mm thick - need to also get 1.5mm ones as im worried they are a bit thin. Keeping it 100% quartz - some stems Both 12mm OD with 1mm and...

I wonder where the tm2 pcb and most of its components are made?

I have both the TM2 and the Wolkenkraft FX Mini Ultra - the mini is a pretty capable device being so small but the stem is a bit on the small side - its great for stealth as you can fit the whole device in your and pretty much cover it and battery life is ok for something so small maybe four or...

The problem is with trying to rate something like a vape is any rating is very subjective - also comparing vapes is like comparing apples to pears and perhaps in some cases to oranges. Even the weed your testing with will make a difference as in humidity level, different strain etc Some vapes...

Looked at the 510 threaded version again It just about works with my mod but it gets too hot as in battery i think when trying to push the 70w it needs to get up to heat. With one of the fancy dna two battery ones it should be fine and possibly be able to use tcr and regulate it - but...

Bits arrived. The batteries are mounted the wrong way and you cant really hold it in one hand with the momentary toggle switch - i want to make it hand held so you have to touch the batteries when in switching on so you can feel how hot they are getting - most people will realise 50C is hot...

With work on the unregulated version progressing with a new heater i have made a regulated version of it with the closed bottom tube All connected up to one of the mini pids Still deciding on giving it a go with the batteries or via my mains power supply. Either way will need to do some...

Thanks it was a bit sore earlier when typing but is ok now - tbh i have got used to the minor burns - in the vape building game it helps to have asbestos fingers Have got an update to the build but not the unregulated one at the moment - im heading back to the other regulated thread for it...

Take a read of the other thread about a regulated version there is no end goal As mentioned the large tube version wont work with the open ended version but that wasnt actually part of the original idea as i wanted a pure glass air path and the larger straw needs to draw air over the nichrome...

I have been able to drill the boro but isnt quartz that much tougher? Just gave the new longer open tube heater a go with some new batteries - i think i need to be a bit careful after about 10 secs i could see the coil start to glow.

Yes i have avoided solder from day 1 of the builds - i suppose pure silver may be an option if i needed to join stuff near high temp areas and couldnt get away with crimps or screw terms.

Well i am really struggling to make the same piece again and it seems the first one was a bit of a fluke. No matter what tool or cut i do i seem to get a hairline fracture which eventually spreads - i got through about 6 tubes trying. I did manage to make this little version Actually got a...
