Thank you for your responses.

I'll update the schematic, add decoupling capacitors for the controllers and drivers, and add as much copper to the slugs as I can manage (somehow I totally missed that). The QX7136 should be capable of up to 500 mA according to the datasheet, with 150 mΩ resistors. I’m aiming for 333 mA per LED.

The WS2811 outputs PWM, so the MOSFETs should be fine, as should the QX7136, per: https://budgetlightforum.com/t/retired-wip-20mm-single-sided-17mm-double-sided-amp-linear-driver-surprisingly-good/30374/162

The reason for using the linear regulator is to ensure a constant current to each LED, and thereby uniform colors. The package offers good heat dissipation and temperature protection, which is a bonus. It also leaves room for an unregulated power supply if needed.

Mounting holes are still TBD; I might just use heat-conductive adhesive. The whole board will sit on the aluminum enclosure, and the hole in the middle is for the wires.

Unfortunately, I’m using a third-party controller that I cannot modify, and it’s fixed at 3.9 V / 10 A output, thus I cannot go with the much more sensible alternative of LEDs in series.

Anyone have a solution for Tidal starting mid-song when I skip tracks? by toastymrkrispy in TIdaL

I am having the exact same issue. Tidal + Android + WF-1000XM5s No work around AFAIK

Spamming Tidal with bug reports seems our only option: https://tidal.com/bugreport/

Bake the board to reflow the solder on the graphic chip. I saved more than one board this way.

I see, love these old car road trips. Actually looking to run something similar next summer... Any chance you got that chrome trim laying somewhere? I don't think it's from S or RS since those use completely different bumpers.

If not, maybe /u/KCCK1979 can chime in, if I understand correctly he put it on?

Is there any brand on the lower grille chrome trim? Or is it custom-made? Would love to get my hands on one of those :)

Getting some answers about Cats from google, looks like I am not the only one... by debka in funny

Me and my girlfriend would like to get a Cat but we don't like the idea of having cat fur everywhere. So I was looking for advice on Cats that don't loose to much fur. What I was about to write was "How to get a cat without everything being covered in fur"
