    DNA40 line-up...

    DNA40 in a 1590A (92.5mm x 38.5mm x 31mm) with a 26650 batt... yup it fits lol if dremel the side walls some. No depth room for a screen bezel though. I love the small size of this case!

    About fuses and choosing the appropriate fuse for your mod

    Yes, I've used those fuses - not with the DNA yet though, only with my unregulated MOSFET coil build/test mods. Easy to work with, easy to solder. I need to test to see if it will also provide reverse polarity protection for shorting of the batts with the DNA with dual parallel batts, haven't...

    About fuses and choosing the appropriate fuse for your mod

    I cover the fuses and exposed wiring ends with heat shrink tubing.

    About fuses and choosing the appropriate fuse for your mod

    28A is not trip, it is hold if using 4x fuses (2x on each batt). The goal is to protect the batts from reverse polarity damage from the huge current dump from shorting the batt if one is inserted backwards as well as not interfere with the current requirement of the DNA40. Littelfuse 2x 7A...

    Raptor Flip-Top VV Mod with 20A, 120W dc/dc converter...

    There is no resistor across G-S on the P-FET. There is a 47K resistor across G-S on the N-FET though if you're using the no idle current drain circuit. The current batteries I use are Sony VTC3, VTC4, and LG HE2. There are others that seem to be equally good (Samsung 20R, Samsung 25R, and...

    DNA40 line-up...

    Thanks guys! @rhelton - ColorFabb's copperFill is 80% copper mixed with 20% plastic. @ MechanizedZen - the large screen DNA40 should be available soon, not sure of Evolv's schedule for release though. @BlueridgeDog - I designed the bezels and printed on my 3D printer. @Nautilusfan - the 2x...

    DNA40 line-up...

    The build is the same for the three versions with electronics down the center and dual 18650 batts, just a bit of a design difference... Avani v1 design - black buttons, 3D printed bezel, maroon Hammond 1550P, have also done this version with 3D printed case using CopperFill Avani v2 design -...

    Official DNA 40 introduction

    I am uber special. :laugh: lololol I'm with the beta team - we were given the board with the large screen to test. Yes - it does Celsius.

    DNA40 - large screen version with detachable cable... DNA40 regular screen compared to DNA40 large screen... the large screen text looks blue, but it is white text, dunno why my camera picks it up as blue...

    Raptor Flip-Top VV Mod with 20A, 120W dc/dc converter...

    Wiring gauge guide written in the lower right corner of the wiring diagram posted in the OP. 18AWG: input/output (+/- atty connector, +/- batt, P-FET Drain and Source, and Vin/Vout/GND at the board) All remaining wiring: 24AWG

    About fuses and choosing the appropriate fuse for your mod

    lol yes it is getting a bit confusing. :laugh: I've been adding 1x 7A fuse on each batt with dual parallel batts (14A total Ihold, 28A total Itrip). I personally have had no issues, but I'm running the DNA40 at 400F at 25W. For those running higher watts, higher temps, and max preheat amps...

    Official DNA 40 introduction

    In response to Robert Ellis's video angrily bashing Evolv, the DNA40, and the beta testers... People should know - and contrary to what Robert Ellis said/assumed - when the glitch was discovered (and yes by the beta testers) Evolv worked day and night to find and fix the cause and thought they...

    Mike n Tibs DNA Mods!

    DNA-TP User Group I thought you were there already, Tibs. We're currently talking about version 3 of the DNA40.

    Evolv Technology Owners Discussion Thread

    Disappeared from ECF, maybe lol, but no one has *disappeared* as some of us have moved over to FB instead, and the screen issue for the DNA40 has been resolved. If you have an issue with the screen from a previous version of the DNA40, Evolv exchanges at no charge... DNA 40 RMA form For...

    Raptor Flip-Top VV Mod with 20A, 120W dc/dc converter...

    The 20A boards can handle high loads if circuit resistance is optimized for minimal interference. Plus these boards are typically used with a 12V source in electronic applications, but we use an 8.4V source.

    Raptor Flip-Top VV Mod with 20A, 120W dc/dc converter...

    Using/not using Sense is not the problem as Sense would only help the converter compensate up to 0.5v loss at output. If you're trying to run a 0.32 ohm coil @6v - that's 112W and 19A. That kind of load alone will cause some batt sag and output voltage drop, so you're most likely not going to...

    DNA 40, NR, Nickel Builds

    It took me a few tries tinkering with different coils - gauge, wraps, single, dual, twisted, that sort of thing - to find the coil that's right for me, then tinkering with the temp/watts setting that is right for me. I love love love the twisted 34g dual coil it absolutely rocks with crack...

    Official DNA 40 introduction

    <Mamu, this is the first place I've seen that stated with certainty Evolv is having tests done to see if nickel is getting into the juices -- you know for a fact that that is being done?> Yes - I personally, and also the beta group, were told last month that a sample has been sent to a lab for...

    Official DNA 40 introduction

    I'm hypersensitive to nickel with allergic reactions to contact with it - major itchys with rash, welts, blisters. When I was a kid, had to have the nickel wire that was put on my braces removed the same day ended up in the ER with a severe allergic reaction in my mouth. I have to sew on cotton...
