The BOM for the components alone without the print is USD240. Why is the article talking about USD100?

Good job

The second connector pin from the bottom is connected to what's almost certainly a ground pour, and this is in line with the through hole labels together with your diagram. This is your black wire.

I would bet money on the rest of the labels (and your diagram) being correct too, so red wire goes to middle connector pin.

If you're fairly certain that blue is in its correct location then we're done: green goes to bottom pin. If you are not, we can take a closer look.

From the top down, that would be

Blue
X
Red
Black
Green

I'm a big fan of Radiohole, especially their song Grape ("I'm a grape, I'm a raisin.")

Not 100% clear what you want to achieve, but you probably want an alias.

Does this do/can it be used for keeping track of bicycle maintenance? Mostly which components are used (tires, brake pads,...) and when maintenance was done and so on?

...of DNA

Isn't Svalboard the new(?) hottness in keyboard-land?

I never designed a speaker. I have been looking for designs a few weeks ago, and there's too much stuff out there and too little to go on if it's actually worth it/better than HiFi speakers I already have. Maybe some day, if I find a good bookshelf speaker project that seems achievable.

Awesome, thanks for the reply. I've been curious about printing speakers myself, but it seems like a daunting task.

Do tell about the speaker. Did you design it yourself? What does it sound like?

I think OSMC does this.
