Show HN: I made a new sensor out of 3D printer filament for my PhD

#1
Here's a "behind-the-scenes" look at my development of a cool sensor during my PhD (electrical engineering). This sensor is only about 1/3 of my total research for my degree and took about a year.

I've been on HN for a while now and I've seen my fair share of posts about the woes of pursuing a PhD. Now that I'm done with mine I wanna share some anecdotal evidence that doing a PhD can actually be enjoyable (not necessarily easy) and also be doable in 3 years.

When I started I knew I didn't want to work on something that would never leave the lab or languish in a dissertation PDF no one will ever read. Thanks to an awesome advisor I think I managed to thread the needle between simplicity and functionality.

Looking back, the ideas and methods behind it are pretty straightforward, but getting there took some doing. It’s funny how things seem obvious once you've figured them out!

Oh, I love creating GUIs for sensor data and visualizations as you'll see -- it's such a game changer! pyqtgraph is my go-to at the moment - such a great library.

That's super cool and I hope you don't mind a little bit of unsolicited feedback but the first question everyone's asking is "what does it do?" At present the blog post starts out with two paragraphs talking about the format of the blog post and the applications but not what the sensor actually measures.

Paul, what an amazing project, this is what hacking is all about. Congratulations!

Definitely try to explore the commercial side of your invention.

It wouldn't hurt to talk to an IP lawyer, if you're still in Uni they usually have people there doing this and you can just go talk to them, free of charge (for you!).

I'm generally against the idea of patents, mainly because of people who came to know to game the system and exploit it (patent trolls etc...) Your project is a real thing with real applications, you definitely deserve a share of whatever commercial benefit this could bring to the world, :D.

Good point -- I need to better explain what "bend localization" means on a more practical level pretty early on.
