> If you are serious about PCB design, you need to do things manually. this will not always be the case, you know. I hate that this blog post is effectively an HTML commercial for the product they are selling, but I have to admit that they are headed in the right direction. Prior to tools like KiCad, "serious" users did tapeout by hand. Prior to the transistor, "serious" electronic engineers used vacuum tubes.

Hey, founder here - we really value feedback from HN and I try to cut out all of the commercial aspects and just write something interesting. Do you have some feedback about what we could change about this article to make it less like a commercial?

nothing specific; all "here's how I used this tool my company makes to do a thing" blog posts on the company site itself are just inherently ads.

I find it disingenuous every time I see it, because (while nothing is done to imply this) it reads, at first, like a genuine blog post someone wrote on a personal site.

we all read enough blog posts every day that the site hosting the blog can easily go unnoticed, and I feel like companies hope that "blog fatigue" will make the post look more spontaneous and genuine than it is.

I often forget that YCombinator is a greenhouse for companies to be fed and watered and pruned so they can become standalone entities out in the wild, and that this means that I'll be presented with blog posts about products from the product-makers themselves.

The problem is that this often isn't physically possible. Keyboards are rarely fully grid-like, so you have to take into account that there is a row/column shift. Modern keyboards have features like per-key RGB and hotswap sockets, which eat up a lot of valuable space. And then you also have to fit half a dozen traces in between two switches for the key matrix connectivity. An approach like that might work for a triv…

Keyswitches are like 20x20mm...there's an abundance of room for a little ~2x1mm diode within the footprint.

It's a bit harder if you go through-hole. When you can't fit it "under" the switch footprint, it becomes harder to auto-route it-- there might not be a space specifically where you want-- maybe you want to move some diodes around to shave a couple millimetres off the PCB footprint to save a nickel, or maybe you need to rotate a switch (for example, the + and enter on the numeric pad) and end up with the 'standard' position fouling some other part of the layout.

It takes an evening or two to manually route a big battleship board, when you're not worried about RGB or having to do clever stuff with USB.

Your website on my phone cuts the text on the left with Firefox. Even zooming in/out doesn't allow me to see it, only desktop mode.

Thanks for the feedback - fixing it now.

Other than that nice idea!
