I checked the video and I saw what you say Bish. You fire the device and you vape. Temperature is raising and when it reaches the limit, it stops. That means that its a temperature limit device. It also means that you never vape on the temperature you put on screen. Screen shows only where it will stop and not the temperature you want to vape. Is this right?

I am just trying to figure out if VIR has anything to do with dna.

The DNA 40 does not stop when it hits the temp limit. It simply reduces power to ensure the temperature doesn't rise beyond the limit.

It does stop it gives a temp reached error and no longer heats the coil

That's not correct. Despite the fact that it displays "temperature protected", it still continues to deliver current, albeit at a reduced wattage.

It's not an error it is just a notification but it keeps on running at lower wattage

Correct.

It is easy to test. Keep pressing the button and put few drops. If it starts again without release and repressing the button the it still works.

An even easier test is to set the wattage at max (40W), thereby basically guaranteeing that you'll hit temperature protection. Take a puff and notice that it doesn't shut off.

Aal is right it does continue to run and the moment it senses the coil temp dropping it increases power to maintain the temperature the user set. Apparently it checks coil temp a thousand times a second and varies the power to maintain it. Priority is heat up time so if you set the lowest temp 200 F and say 8 watts it will actually fire at much higher power to achieve a fast coil temp and then regulate down to whatever is needed to maintain temperature. You can however set both temp and Watts.

Despite the fact that Brandon and John from Evolv beat us (and I mean GG of course) to the market with the temperature control I want to congratulate them and wish them much success with the DNA-40. I believe they did a fine job with the chip. I can now tell you that back in 2011 over coffee in Athens Greece Imeo shared with me a new idea he had of instead of controlling voltage or wattage he plans to design a chip to control the temperature of the coil and regulate it. He said imagine no more dry hits, no burnt taste.

Sadly Imeo doesn't have the resources that Evolv have and probably that was instrumental in determining who crossed the finish line first in the race to temp control. Anyway I don't mean to be negative towards the fine folks at Evolv, besides I have no idea when they conceived the idea, I just wanted to let you know that Imeo told me all this back in 2011 and frankly I thought he's dreaming at the time.

What's important is that there are some great minds around making vaping safer for the newcomers getting into vaping.

Looking forward to the new video in 2 weeks. I hope it's not another 8 minute wall of text though ;)

For the record, the reason I responded with details about the DNA 40 is that you asked a specific question about whether the DNA stops powering the coil when the temp limit is reached and the initial responses you received were flat out wrong (despite being from one of the first reviewers!?)

you did well dil, thanks a lot for the info. I hope that in 2 weeks I will impress you.
