The resistor is from Vcc (+5V) of the USB connector?
correct, USB VDetect -10k res - +5v USB.

That is pretty brilliant!  Really nice work!!!

Is the +5v another one of the pins right on the USB connector as well? Been thinking of doing the same, and haven't gotten everything desoldered to take a look at the daughter board itself.

yes it is. it is the far right pin. you can do that but i found it easier to bend the leg of the 10k resistor over to the input capacitor of one the daughter board's charging chips.

i circled the place i connected the 10k res to in red (be sure to solder the resistor leg on the + side of the ceramic capacitor, the positive side has "C4" in white). it is USB (VBUS) +5v.

Sorry, if this is dumb. But solder it directly to the ceramic capacitor?

Edit: Also meant to add, or to one of the pin holes next to the capacitor?

@joelhammonds - yes, the positive side of capacitor. those pin holes are vias don't concern yourself about those.

another option is this pin of the charging IC, it's all on the same circuit, whatever is easier.

TBH and don't get offended, if you're not that familiar with circuits or soldering this can end up being a very difficult modification and a big headache. i didn't mention this but i also had to grind away an aluminum post for the DNA 60 to fit.

No offense taken, cause honestly I'm not all that experienced, but I'm thinking I'm gonna give it a shot anyway. And I've opened it up and kind figured it would need some internal modification based on the specs of the new board. I'm going for a high risk learning experience. Haha.

Thanks for the pics I am going to be doing the same this takes the guess work out of it.

here's another pic of the install. you can sort of see where i connected the 10k res to on the daughter board. it may help some......
FYI, you need to install the screen ribbon to the DNA 60 before soldering mating the two boards. i also removed the DNA's up and down buttons (not the entire button, just unclipped the actuators).

Good to know thank you. I got a rework station coming pretty excited about that. I was worried about tackling this there is allot work to do on the daughter board.

Here is the one I got what do you think?

@Rob_H wow, all that for $50, nice. definitely beats my 40w radioshack pencil iron i use. when you get it let me know how it performs, especially the hot air rework part. might get one...

Was suppose to be here yesterday but the mail is late cause Christmas I think but should be early next week. The price was really good and considering it wont be used in a commercial application just for my occasional needs it should be fine I think.

I'm getting some strange behaviour which I assume is a bug?

I lock my DNA60 and then remove the battery but not the atomizer, which is warm. When I put in a new battery and fire it and instead of keeping the old initial resistance, it changes it to the resistance of the atomizer just before I removed the battery. Does anyone else have this happen to them? If yes, anyone care to try with a DNA75?

That happens on my 75's as well, unless I plug in the usb so as to not lose power to the board. If I forget to plug in the usb, it will take a bit for the refinement to readjust to the original res. I believe its actually reading the res of the atty when you insert the new cell...
