Check this out - a printed circuit board.
No, literally printed, a 3d printer hotend extruding solder traces onto a board!

That is really cool but Iāve got to wonder about the long term durability of a circuit board like that. I envision the solder traces eventually peeling off the board and shorting out.
It was great to see another Binky episode after so long but man, I couldnāt help but look at all of that and go āwhy??ā.

I know right? Like someone needed to take them aside and tell them about esp boards and pcbway 
- even 12v LED strips!
Still, interesting to see what they came up with and a ridiculously complicated bespoke solution is very on brand for them after all.
I expect some sort of conformal coating or epoxy to waterproof and protect everything.
āWe do these things not because they are easy, but because we can do it in a way that makes them artificially hard, because that goal will serve to organize and measure the best of our energies and skillsā¦ā

Iād like to see a build video of their trace printer. 
My understanding is that this is a sort of breadboard - they are going to get it working, modifiy as needed and then do a proper PCB.
I do have concerns with their guard flares though, which Ivan Miranda printed for them in PLA - I think they could have saved themselves some grief by taking a mould there and then! 
Neat! (or just interesting?)

Sure, thatās their intention. Itās still a stupid way to approach prototyping something like that, though.

I really wanted to see the peeloff but i grew bored and started clicking through, nrver found it! Interesting concepts!

I am as naive as they are, but would be inclined to just keep plugging away with PCB iterations and hang the expense - is there a better way?
Nothing youāre probably not already familiar with. Start with breadboard and discrete wires, move to a PCB next. If the PCB is wrong, cut traces and replace them with wires. Once everything is working fine then make a new PCB.
I canāt quite tell how large that PCB is but a 300mm x 100mm PCB is US$55 so hardly breaking the bank!

Considerably less than the solder printer setup I would have thought!
Yeah, almost certainly. And also coming with an additional set of skills.
The whole video was kind of weird. It sounded to me like they didnāt want to make a PCB because they didnāt know how to do a PCB, so instead they modeled a bunch of connections to be printed in solder and then chose locations to put component pins or make transitions from one side of the board to the other with rivets. Which is basically a cursed version of what a PCB is.
Wait till you see their switches!
I had to scroll through a huge backlog on this post to see if someone had already posted the printed circuit board stuff.
My thoughts, while watching the vid, is that itās great for prototyping. But I think Iād want a PCB made for production. I canāt see how that printed board is going to survive the vibrations of being in a carās dash.
Hacked Spotify car thing new pendant alternative?
The juice probably isnāt worth the squeeze but could be a fun project
That would be the coolest pendant! Jogging with the big knob. I hope to get my hands on one of these after they are discontinued. Unfortunately they are rare in Europe and people ask crazy prices for them.
Iām team joystick. (Note this is early stages and donāt know how far it will go.)
