Havensal

Worked. Thanks!

Is there an update I'm missing for the DNA 250C? I downloaded the latest version of Escribe, but it will not detect the board. The PC shows it as an "Evolv USB serial port".

Will these be up on the site soon? How do I get one?

I had 6 boards fail in my DIY mod in the first 4 months, the last was on Christmas day. I've noticed three different versions of the board. The current one appears to have slightly larger components. I actually bought a second board to eliminate down time. Thankfully the Evolv tech support and customer support are top notch.

Just happened to me. Vaping along fine for an hour or so. Went to take a hit and nothing. Blank screen. While I was reaching for a cable to plug into Escribe the error message popped up. I've had the blank screen issue a couple times over the last month or so. I usually remove the battery due to scares of previous board failures. Any answer yet?

More information and less insults might get the results you're looking for. I have been running SS for over a month now, with success. I have not seen much talk of SS problems here or other forums.

This is to only down side of Evolv's excellent customer service. Finding a board Evolv will not fix or replace will be a great challenge.

I have noticed my SS TC goes a little crazy at the temp limit. When looking at the chart the temp goes up smoothly until it reaches the set temp and then bounces up and down radically. It vapes fine, but the chart look all zig zaggy.

It sounds more like a hardware issue to me. Make sure all you connections are tight and that your atty is tightened down properly. Also make sure your 510 pin is clean and dry.

Soldered on a new fuse yesterday. Now the board reboots when I press the fire button. This is without an atomizer attached. So either the blown fuse was a symptom of something else wrong with the board, which I suspected when it blew, or I did something wrong when soldering the new fuse on. Either way this one's going to have to go back to Elolve.

I use a small piece of 3M velcro.

I love my Velocity clone. I have also been using a Big Buddha clone as well. My box is large enough to fit the 26650 RDA on top. There is a ton of room for big NI200 coils.

140W and 30ml isn't pushing the boards. They can handle over 200W but battery safety makes 200W the practical limit. I have no way to know if your iron was the common denominator but it is something almost always overlooked. ESD parts damage shows up in unexpected places often with odd symptoms. A part can be weakened but still function, and then fail under long term stress or just fail unexpectedly for no apparent reason. Again, I have no way to know if that's what's causing your failures, but four dead boards would lead me to look for a common denominator in my shop. A cheapo soldering iron that's not ESD safe would be first on the list of things to never use again. The one you linked says it's ESD safe and has good reviews, so hopefully it lives up to its description. [/QUOTE] Thanks for the input. I'll keep this thread updated.

You are not alone.

Right now I'm using a RS 15W el-cheapo. I have a better one on order. Leakage could be possible, but I would think that would show itself much sooner than I've experienced. The boards are lasting anywhere form a week to a month of nearly constant use. I also have a DNA40 and two Yihi devices I've built that have been running fine for months. I know I am pushing these boards hard, between 60W and 140W, over 30ml a day at times.
