Just got an email that my boards are on the way!
I've been really happy with the service from Osh Park. I'm only a couple states away from where they ship (Oregon) so I usually get them within 3 mailing days of the email notice.

Good luck with the board fsors.I wanted to try that mosfet, but mouser doesn't have them in stock. I found one similar enough:http://www.mouser.com/ProductDetail/Vishay-Semiconductors/SIR800DP-T1-GE3/?qs=sGAEpiMZZMshyDBzk1%2fWi0mX49X1Ojk8bkorZS29FXY%3dFor this first version of the board, the holes for 24 gauge were perfect. Holes for 16 gauge were alright, a little tight. The vias on the drain pad were too large, too many and were sucking up the solder. The exposed copper for the drain on the back of the board cold be covered with solder resist. I've made a revision to the pcb to address those slight issues https://oshpark.com/profiles/david4500
I assume you are referring to the boards in my possession now? How would I cover it?
Another nice board David. Man, if you would have just did that one for the 7157 p-chn you would have saved me a couple of weeks and a bunch of headaches.
In some cases I think it would just be easier to use the p-chn. Don't hold your breath, Im still learning all this and it will take a while. Knowing what you want and how to turn it into a board are totally different things. Mabye not to you guys and gals but to me learning the software and knowing what to put where and how to isn't easy. Its ok though. I will learn it and not bug you guys.
Just pointing out somethings that could be refined & improved upon on the first version. Functionally they should be just fine. You'll be (hopefully) insulating the whole board fully anyways after soldering and connecting the wires. Heat shrink, epoxy, hot glue, whatever.Thanks. Seems like the nfets and usually superior so I haven't even thought about messing with those really. I'd love to see your board. I'm sure your hard work really paid off.
Glad this thread is still alive and kicking and so many great things have been updated in it. fsors you old dog, how you doing?
Yes the old dog is still kicking and I'm well too How are you dz? Nice looking triple ya got there.
Wow nice looking mod. I'd imagine they'll fit for you. Check out the dimensions listed on oshpark. I'm working on a dual mosfet board right now that will be even smaller.
Good man, not really doing anything these days, thank gawd. I have been playing in CAD for sometime and the triple is one of my creations, I made it so that top plate can be switched out and you can do either mech like that, blank, DNA40 and OKR with a master on/off and pot, things get a little tight under there with the depth of the volt meter. Here are a few of my creations and always playing and putting more out https://www.shapeways.com/shops/xmods
I think they will work perfect under there. I did have one question, I see SW +- is that just a standard slide switch for off on?
Still learning a lot here and have already started my own mod from info here as well as ecf. I am very interested in the Para board but correct me if I'm wrong but aren't the only features that are missing is a 200 ohm pot and a couple of fuses?
Nice 3D Printing! I really need a 3D Box for a sx350 chip that I have. I want one that's the size of a GBox with a mount built in for the chip, an on off switch mounting bracket built in, a hole for the screen, holes for the 510 and switch mounting on top like in my mod posted above in this thread, the dual 18650 batt sled built in non removable, holes to drop in mags and no usb charge hole as I want the batteries to be removable. It would also be cool if I could have my logo on the box as well. Glad you are still creating as I love your work!
I can try but the dang thing on the back of the chip (brain farting atm so cant remember what its called) is huge, I have seen some cut the silicone from the screen and lay the board flat on top of the battery sleds to make that work, sadly I think everything will be close to a b size

Nice! Glad people are using them. Sucks when I see shitty mods on facebook or ebay with them... or vape shops selling the stickers for $5... oh well.I took the files for the 4x6 prints and had them printed online on walmart's site. When I did it, they had a deal for your first prints. On matte photo paper, I think I got 50 for $2. I just cut them out and use a bit of epoxy. Stickers would be nice but likely more expensive.Here's an 8.5 x 11 print also: https://www.dropbox.com/s/c6qvkynzd8b7of0/keystone%20labels%208.5%20x%2011%20print.png?dl=0
New member here.... I love this thread.I'm so inspired by these projects!
For the nfet, the rds on is too high. You'll want around 2 milliohms. Vgs th is also slightly high, 4.5v. You want it to be less than 2.5-3v. If for any the smd pcbs, of the packages shown in the data sheet they are all too large.I think Craig has posted some well suited pfets in the past if you look through his posts.Got the quad board today:When soldering the drain tabs on the back, I didn't realize the solder was flowing though the vias to the other side.
