JTree Posted February 10, 2016 Author Report Share Posted February 10, 2016 The title says it all I guess. I'm not sure how much it's pulling because I'm not at home, but it will blow the fuse in a cigarette lighter usb adapter :/ Any ideas? I just got this board back from evolve after the first one fried on me. This is sad. Both times it worked for a day and then died Oh well....guess I'll pull out the back up mod for now.

Spector NS5 RD Posted February 10, 2016 Report Share Posted February 10, 2016 the dna charging circuit should only draw one amp while charging. provided your power source is capable of providing at least one amp. i'd say ditch that cigarette lighter usb charger. it could be faulty. your usb cord could as be damaged causing a hard short blowing the fuse in the charger. ditch both to be on the safe side. try an actual wall mount (wall wart) usb charger that is rated for at least one amp on the output and different usb cable.

JTree Posted February 11, 2016 Author Report Share Posted February 11, 2016 I should have mentioned that I had already bought a replacement 12v to usb adapter and it blew that one too and tried different cords. Just for giggles I plugged it in to 2 different wall adapters tonight that I knkw to be good. No dice. On the plus side, it didn't ruin the wall adapters like it ruined the car adapters, but still......another board failing likely. I really want this to work. This board is the only accurate temperature limiting expierience i've ever had and both builds lasted a little longer than a day....enough to solidify my resolve, but this is frustrating.

JTree Posted February 11, 2016 Author Report Share Posted February 11, 2016 I'm tempted to plug it in to a computer to see what happens,but I'm concerned about blowing out a usb port. Link to comment Share on other sites More sharing options...
retird Posted February 11, 2016 Report Share Posted February 11, 2016 How abou a few pictures of the internals of the device? Which device do you have or did you build it? Link to comment Share on other sites More sharing options...
JTree Posted February 11, 2016 Author Report Share Posted February 11, 2016 Built it. I'm still away from home, but I may open it up tomorrow if I have a screw driver that's the right size with me. I triple checked everything before I sealed it up, though, so I doubt we are going to see anything wrong. Link to comment Share on other sites More sharing options...

Spector NS5 RD Posted February 11, 2016 Report Share Posted February 11, 2016 honestly it sounds like a hard short somewhere. maybe a stray piece of copper wire is somewhere it doesn't belong? maybe a something like, what i call, "solder free floaters." that have worked their way into the charging circuit portion of the board. can you shine a light into the usb port on your dna and see if anything like that is inside of it?
