  2. Mod resistance issues

    in General Discussion

    Posted

    I ended up making a copper slug and measured my resistance to be .005. I set it to .004 and ran with it. While the temp control does work much better now the mod is much more sluggish in power mode. If one wants to see what I am talking about, set the mod resistance to .07 and see just how much of a difference there is in power mode. I just wish the power mode performance stayed the same regardless of the mod resistance setting.

    Just run the battery analyser on my WisMec.

    Batteries AW IMR 3000mAh x 3

    Run 70W into 4 x 100W power transistors in parallel on heat sink, showing 0.26ohm.

    Gave me 29.5 Wh usable. Changed the soft cutt off to 2.8v, is that OK?
    I know best not run these lower than 2.5v but at 7.5v total I ain't going to get much out of the DNA 200! lol

     txt WisMec 3 off AW 3000mah discharge profile.txt      

    Couldn't upload as .csv so opened in word pad and saved as .txt, Just
    rename changing .txt to .csv Should work?

    Hope this helps someone. :)

    I'll run the test again using my Sony VTC4's @ 50W this time.

    I also run the recorder while doing it but can't find the file. Where does Escribe normally save those on Win8.1

    I think the word you were looking for is resistor. Transistors amplify power or functions as a relay depending on how it's used.

    [QUOTE=mactavish]If you get a chance, put up a quick photo of you wiring and this rig. Interested in how you connect it to the mod. This is affordable, but on the large size, guess it can't be made much smaller.



    Here you go. I put a plug between the base and atty so you don't have to spin the whole setup onto the mod. Screw the atty in, plug it into the rest of the rig, and start the test.

    [QUOTE=Alex faught]Didn't turn out all that great this time lol. The paint can had a crappy nozzle. I will buy a new can soon and redo it. I was surprised how easy the thing came apart. I also saw the thread in the current topics discussing the ribbon cable being ruined by the fire switch. So I figured I would take care of that as well.



    Nice work. I'm glad the teardown went smoothly for you. I'm in the middle of attempting to strip down my RX 200 (black) to switch the board out for the DNA 200. I originally purchased the Lavabox, but had to send the board in due to the board getting stuck when pressing the firing button. I recently purchased the RX200 with the intention on switching out boards. I do like Joyetech's board, but only in wattage mode. I hate the 3 clicks to scroll through the temp settings. I much prefer the DNA 200 for customizing curves. 

    Anyway, upon inspecting. I found that the 4 screws (middle to bottom) allowed me to pop the screen cover off. That's where work has halted. Wismec have glued the board in place ever so slightly. This doesn't appear to be the case for you on your DNA 200 version. I removed 1 gold or brass plated screw from the bottom right of the board. Is there anymore screws holding down the board that you can think of? I also have a duh moment going on. I don't understand how the board is fitted under the firing button, as the enclosure covers the firing button up. I have noticed that Wismec have soldered long positive and negative wires coming from the 510 to reach the pads located at the bottom of there board. I can see a minor alteration being made there. I may need to shorten those wires as the DNA 200's contacts are located at the top of the board for the 510. I'm assuming the 2 screws located at the top of the battery sled and the top and bottom of the mod are holding the sled in place. Is this correct?

    For anyone looking into doing the switch. Please do NOT follow my steps as I could be completely off the mark. I've not done any prior research before attempting any of the above. The mod cost me a little over £30. I would not recommend doing this if the RX is your only mod.

    Edit, 

    I thought the positive and negative wires looked a little thin. Thanks for providing those images ChunkyButt200. Now to figure a way around removing the solder from those 510 pads. Those wires are way to short to pull the board down a touch to gain access to those pads. I can see this being a pain the backside to complete. Not to mention, the firing and wattage buttons need sanding down from what I've seen on reddit. [/QUOTE]


    If it is anything like the dna 200 version There is an extra screw underneath the sled that is exposed when it is moved out of the way.

    I work in the radio communications field, I am very familiar with electronics. As I have previously stated, I have checked them on several meters (including a very expensive fluke). .07 seems to be the sweet spot for it to read correctly on the screen and have a quick ramp time on kanthal builds. I set it to .004 and the temp control works well I just have turn the wattage higher in power mode to achieve the same performance. That I really don't care about, it's the ramp time that I am losing that gets me.
