I write code for fun and profit.
TBF, I think the last two months are a clear indication that corporations don't hold as much power as people ascribe to them.
Can promise you that no corporation is happy with stocks being 11% down and even more tarrifs on the way.

I've been on a cooking bend the last couple of months, it's a fun hobby to get (back) into.
Problem I'm running into though, it's way too easy to make a lot and then eat it all 🤣

Yeah, and should be a stable oil, not something like sunflower or rapeseed.
I had coconut around, should be fine? 🤷

I was using Easy EDA from JLC PCB, just because I also were ordering my boards from there, and you can have them solder components to the board for you.
I use it for components that are surface mounted and very hard to solder on your own. I solder the rest myself.

On a pcb, this is usually done by just having big slabs of ground all around everything else.
Now, for your usecase, it probably doesn't matter. Putting it into a calculator, it says 4 mil traces should be enough, which seems like you have covered? I can't eyeball them 😅

The further away two wires are, the more they will radiate an electric field, which makes for bad vibes all around.
That's why high speed data wiree are always done as "twisted pairs" - the ground and data lines being as close as possible.

The reason it's good to have a lot of ground near your other wires is because when current flows in one direction, it must then (actually, simultaneously) flow in the other.
If you have a ground right next to another wire, the reverse current flows there, so the electric field is very small.

btw, I am definitely just a hobbyist, all my advice should be considered on that level or below 😅

It's usually done by using a two side board, and having all the ground on the bottom side, all other traces on the top, and using vias (holes filled with copper) to connect to the ground when necessarily.
But even on the top side you would usually fill in empty space with a ground plane.

It means that you don't have individual wires for ground connections. Instead, all the space not occupied by another wire is turned into a big plane of ground, and you connect to that instead of connecting traces for ground individually.

They either take an external PWM signal for dimming, or are just always on, switched in pairs of 2 with that little dip switch thingie on the board.

Found it. Was really fun work.
Also I have a thing for wall swithch control for these somewhere.

I did a board to house 8 led drivers with dimming control, and a separate esp32 board for dimming control, integrated with home assistant. Worked surprisingly well, will dig up some photos.

You should only connect positive and signal traces, and then do a ground pour / ground plane for negative. Makes it significantly simpler, and you have better current return paths with multiple components.

Thin traces can be a problem for power depending on amount of current. When I have space I just slap on chonkers of a trace 🤣

Hey, this is super cool!
I ended up playing with custom PCB as well recently.
Since this is only power, it won't matter, but you should be avoiding 90 degree turns in signal traces.
Also, for power, did you calculate how much current will flow?

I'll need to look at more of this, but yeah, wouldn't guess it was AI even on repeated watch.
Of course, this is all of 6 seconds of footage.
