       | Altium offers a simplified free version that's web based and
       | allows for collaborative review. I've never used it though.

         | This is what I was thinking. Our hardware engineer shares his
         | designs with us using Altium. I don't even have to have a
         | license to view it on the web. We're not in the same
         | organization either. He is a contractor, the license is his,
         | and he can share it with whomever he wants via email like a
         | google doc.

       | It would be cool if GitHub allowed rich interaction with PCB
       | files like this. I guess it would help with open hardware design.

       | Looks good. Re: the site - the silkscreen / statement of which
       | chip is which would be very helpful. I imagine you could make a
       | shiny html canvas area and permit per-tag feedback on specific
       | points (bonus points for a floodfill-detected 'label net'
       | tool...)

       | Rich annotations on boards would be nice. More than what you can
       | normally squeeze onto non-printing layers. I don't mean as a
       | feature to add to the site, I mean the entire site IS partly this
       | and I like the idea.
       | 
       | A way to discuss and explain things about a pcb that aren't
       | easily written right on the pcb, like what happens in classrooms.
       | 
       | I often see myself drawing something a certain way on a board
       | going up on github/pcbway/oshpark, and thinking someone else is
       | going to "fix" this some day because it's not obvious why this
       | bit here is drawn exactly this way, and I'm not cluttering up
       | dwg.user with a paragraph of text for every other square cm...
       | 
       | And surely I am guilty of committing that same crime myself come
       | to think of it.
       | 
       | This could help with that.

         | This is very helpful feedback, thanks! My mind goes to a few
         | places when you talk about rich annotations on boards.
         | Something like virtual sticky notes that are tied to specific
         | areas on the design might be kind of fun. I hope to avoid just
         | a list of screen grabs and paragraphs of text on the page.

       | I think it is a nice idea. I think having a place to provide
       | eagle files might be an idea as I found myself chasing traces
       | that at first appeared to be NC antennas that ended up being just
       | a vertically flipped image I misread. It makes things a lot
       | easier to view multiple layers in a single image, if that makes
       | sense.
       | 
       | Regarding your circuit example... have You considered providing
       | holes for mounting of heatsinks into account? I know there are
       | sticky backed heatsinks available like those used on stepper
       | drivers but I have always been partial to clips or screws,
       | especially on power transistors. Likewise providing board mounts
       | and clearances from board edges for dielectric properties is also
       | a good idea.

         | Thanks for your note, I agree. I think it would be great to
         | have a much better viewer. I worry about relying on raw design
         | files because the EDA space is so fragmented. Everyone is using
         | different tools and they really don't make it easy to bounce
         | between design suites. Maybe an embedded Gerber viewer would be
         | better suited?

           | That would be a nice addition, I attempted to right click
           | save images to import into inkscape and stack them myself
           | with transparency but I couldn't. Normally I would just
           | printscreen then cut and paste through paint and then import
           | but Im using a new laptop with compact keyboard(while I drink
           | my coffee and wake up) and cant find the prntscrn function
           | key through the rainbow backlight.
           | 
           | I would think adding multiple options would be best but then
           | again if You did open it up, You may also run into people
           | using the forum for unrelated or malicious files.
           | 
           | On a side note, I recently acquired an Ortur laser master 2
           | pro and a 6040 CNC desktop router and am building a tool
           | chain for small scale, high turn around PCB production
           | (Mainly for my own personal us but would be willing to share
           | out a portion of my eventual production capacity). I would
           | imagine there are many other people doing the same thing and
           | that may be another resource your site may want to
           | investigate. Especially given the ever growing shipping times
           | for overseas products.

             | That is a great thought on the high turn PCB production.
             | You will have to keep me updated on your progress as you
             | get up and running. Although, I'm not sure how to share
             | contact info inside of HN? My Twitter is linked in the
             | about page of the postDRC app if you're interested in
             | connecting.

       | Going from a large corporate environment with strict design
       | reviews, to the only hardware adept person on my small team I was
       | really missing some sort of feedback on some of my (open source)
       | designs. Reddit.com/r/printedcircuitboards roughly serves as
       | this, but I thought it could be fun to spin up something purpose
       | built.
       | 
       | The hope is to build a nice environment to get some fresh eyes on
       | a new PCB design before you wait 2-3 weeks to get your PCBs
       | built. The schematic gets shown in a PDF viewer and any uploaded
       | Gerber files are converted to SVG and displayed for reference.
       | 
       | Long term, I would love to see if this can grow into a repository
       | of open source hardware that could easily be indexed and
       | referenced for inspiration.
       | 
       | Obviously, please don't post any IP protected designs here.

       | Great idea, thank you.
       | 
       | Haha ok that sounded like I'm a out to run off and clone it, no
       | I'm a out to upload a few boards, because you know you can double
       | dip just like the dating sites putting multiple different
       | audiences in front of the same back end, and make a seemingly
       | totally different, differently marketed site where you show off
       | your designs and get likes and a place to humble brag and stuff,
       | and you know that's what I want, since you know I'm definitely
       | only posting boards I already think are jewels. :)

       | I love this idea. As someone mentioned, leaving the safety
       | blanket of a good team makes personal projects a little nerve-
       | wracking. I've only looked on mobile but it would be nice to be
       | able to copy-paste part numbers off the schematic (use case is
       | looking up a datasheet, maybe there's a slicker idea...).

       | Neat idea, here is a few suggestions:
       | 
       | - you should post the solder mask and paste layers. Can't review
       | any component soldering issues without those.
       | 
       | - part assembly layer, same deal as above.
       | 
       | - stackup. You would need this to review anything more than a 2
       | layer board.
       | 
       | Question- have you tried overlaying the renders for different
       | layers of the board? It is hard to review the one example you
       | have on the website. The bottom and top layers are in different
       | places so I have to mentally connect dots.

       | Nice job, this resonates with me that did a lot of hobby PCBs in
       | my spare time.
       | 
       | Posted some comments on your example PCB but the newlines got
       | removed and it turned into a wall of text.
