@ronguest Thanks Ron, that’s very kind of you.

@odd Håller med. Och sen är det väl där den stora ideologiska trätofrågan är, alltså hur vi bekämpar fattigdom.

@furstenberg Seems more or less like my impression. I definitely need to see Rise of Skywalker again before forming a proper opinion, but I should probably also see The Last Jedi again. I’ve only seen both movies once.

I just watched Star Wars – The Rise of Skywalker in the movie theatre. Here’s some first impressions. Some of the things I say may be considered spoilers.

I’m filing these away here for now. They will likely be the speakers of the πi Fi.

Yes, this tutorial more or less works for me now. The more or less part is that the values I read is quite unstable. I wonder if that is because I’m not using a proper power supply for the Pi. I need to investigate further another day.

Slight update on the πiFi: I’ve got a power button an power status LED working on my GPIO test Pi now. I’ll need to go to bed soon but I think I’ll give the level potentiometer a go first.

Tonight I managed to sit down and experiment with the GPIOs of the Raspberry Pi. I think I’m getting the hang of how they work now but I gotta say, this is the first thing I’m doing with the Pi where I feel like it lacks a lot compared to the Arduino.

Anyway, I got some basic buttons working. Tomorrow, or whenever I sit down with it again, I’ll give the level potentiometer a go again.

The plan right now is to 3D print a sort of beta enclosure for the πFi Music Player. Maybe the final product will have an enclosure built out of wood and/or metal, so maybe this is just a temporary solution but it at least gives me something less brittle than a couple of Lego bricks to hold it together while I experiment with it.

We have a 3D printer at work that I can use but I’ve never 3D printed anything, nor have I 3D modelled anything so I have quite some learning to do.

A friend recommended that I’d use Fusion360 because it’s a very capable program that’s also free for academics. I downloaded and opened it, and quickly closed it again because it felt like something completely alien to me.

The same friend then recommended this tutorial on Fusion360 to get started, and while I haven’t applied what I saw in it yet at least it feels like I now know somewhat where to start.
