Hmmm yes perhaps. Imagine a submission titled "A linear filter for DSP you can solder up yourself in a day". 95% on HN couldn't. Would the response "I’m constantly baffled by what electrical engineers call “simple”." be warranted? Maybe.
As someone that has very little idea of what all of that is, I think the title is great and certainly made me consider looking into the implementation.
It might be wildly optimistic, but encouraging people to learn new things, especially by trying, is always a good thing.
I think that's the case for most DIY projects that we have on Hacker News. Most assume that you have lots of X in the first place. It can be lots of experience with programming languages, it can be a lot of space, it can be tools.
