@Herbonius nice find! that tin is the perfect size.:tup: @Pipes by all the responses here it looks like you're going to be pretty busy.:nod: :clap:

http://www.starrett.com/metrology/product-detail/metrology/metrology-products/precision-measuring-tools/fixed-gage-standards/Thickness-Gages/667-4 these are quality tempered steel, should be no health issues at e-nail temps. I've never noticed anything as far as affecting taste. 0.004" thick...

nice progress, very cool with the frequency detection! :cool: good idea to reduce the cap, this application doesn't require much power. you could also drop down to smaller mosfets in your ZVS to gain space, TO220s aren't really needed. I would recommend going to surface mount components when you...

WANT!!! :D that imager is awesome! the thermal conductivity of the quartz, not so much. :science: thanks for posting, looking forward to seeing the liger image.

thanks guys! this is very useful info. I don't like leaving an e-nail running 24/7 so that was one of my design goals for my controller and I'm trying to minimize my run times. currently my session times are about 10 minutes, 8 minutes for the temp to stabilize, 2 for the dab. this is with SiC...

is this on sapphire only? what about SiC or quartz liger vs halo? have you ever used a thermocouple to measure the dish surface temps of your nails? if so what was the range and typically how long of a warm up time for stable temps? anyone know of any studies showing the optimum dabbing...

yeah, no kidding! if the war department knew how much funds I've diverted to R&D she would surely go nuclear! :uhoh::o if it's cool to the touch then a heat-sink is not needed. I think it's probably voltage spikes that's killing your p-channels. not that expensive at banggood...

nice! you have made great progress! :clap::tup: I like the 240 ohm gate drives better, I don't think you need more than this. ZVS failure is usually caused by inadequate power supply but your battery pack should have been good enough. :hmm: maybe the p-channel has too much of a voltage drop...

thanks for the kind words and you're welcome, always glad to assist. :) I started with the basic PID library too but ran into an intermittent bug where the PID would run at a 10 degree F offset from setpoint. I'm not sure if it was my implementation or not but I switched to the ArduPID library...

yeah, I'm a hardware guy too, I have no formal software education, just what I taught myself. I think I have the same PIR sensor, I had the same issues and set it aside. :shrug: I know they make a version of the chip with a narrow FOV but I haven't seen it offered on a breakout board anywhere...

from scratch! nice build! :tup::clap: are you controlling temperature with the nano? are you using PID? if so which one? is there any charring of the work coil from the double windings? you really need a good high current power supply for ZVS drivers or they will lock up and die. lithium...

thanks very much for the warning, this appears to be a common problem. :uhoh: https://www.e-cigarette-forum.com/forum/threads/joyetech-cuboid-150-watt.721356/page-31#post-17291095 "I had a Cuboid for about a day before getting the "Atomizer Short" message at all times. I sent it in to get...

I like the style of the aster, not the built-in battery though. I am leaning heavily towards the cuboid ATM.

damnit @Pipes , you keep distracting me from my e-nail project and itching my VAS. :lol: so I had to scratch it. :D now I have a VC on the way and I just have to have a Project also. :drool: but seriously, again really nice work, you're killing it in DIY! :bowdown::clap: just need to decide on...

really nice work @Pipes :clap::tup: how hot does the coil get now? do you get any smell from the insulation? I couldn't use the stock coils because of this with my e-nail. the temps I needed to run were just too high and the coil smelled pretty bad. the air intake is way too close to the coil...
