Ah. My only suggestion then would be to reduce the likelihood of errors by just combining each pair of black wires with its yellow wire, so it’s one continuous wire. It could still follow the same route and keep your main section less crowded, but there’d be fewer connections to worry about. And you could hold them there with little jumpers like you did in the top right section.

But it takes more energy to split than you get out of it.

Doesn’t splitting helium into hydrogen absorb energy?
Fusion bombs fuse hydrogen into helium.
- Comment on Terrified friends burn to death trapped in Tesla as doors won't open after crash 4 days ago:
I’m talking about the back doors. But yes. I incorrectly compared the front doors in the 3/Y with the back doors of the X.
- Comment on Terrified friends burn to death trapped in Tesla as doors won't open after crash 4 days ago:
Yeah the releases in the 3 and Y aren’t too bad. Most people use them by mistake once or twice (and get the warning about window trim).
The X however is unforgivable. You have to pop off the speaker grills to get to them and then the door also weighs a lot and has to be manually lifted upwards.

One of my parks a rec discs had a scratch on the data layer (“hole”).
Sent a pic and info the Universal and they mailed us a replacement set.
Most studios have an email address for this kind of stuff. Hunt around.

- Comment on Has "Self-Driving" devolved? 4 weeks ago:
Heh, I guess I should have phrased that differently.
But yeah, it’s actually really courteous. Sometimes a little too much. It’ll move over to the left side of the lane if it sees a cyclist or pedestrian on the shoulder to the right. Unfortunately, it doesn’t understand when there’s a 3 ft concrete barrier between me and the pedestrian and will do it anyway. Makes some narrow bridge crossings a little scarier than necessary.
- Comment on Has "Self-Driving" devolved? 4 weeks ago:
The first Model X has Autopilot 1 which was a system designed by Mobileye. Tesla’s relationship with Mobileye fell apart and they replaced it with an Nvidia based system in 2017(?). It was really really bad at the start as they were essentially starting from scratch. This system also used 8 cameras instead of the original 1.
Then Tesla released AP hardware 3 which was a custom-built silicon chip designed specifically for self-driving which also enabled proper navigation of surface streets in addition to the just highway lanekeeping offered in AP1. This broadened scope of actually dealing with turns and traffic from multiple angles is probably where the reputation of it being dangerous has come from.
My HW3 enabled Model 3 does make mistakes, though it’s rarely anything like hitting a pedestrian or running off the road. Most of my issues are with navigational errors. If the GPS gets messed up in the tunnel, it’ll suddenly decide to take an exit that it isn’t supposed to, or it’ll get in the left lane to pass someone 1/4 mile from a right-exit.

Fun Fact: batteries only do this when they’re over-discharged. If you design your circuit right, this won’t happen.

I think that’s a Qualcomm proprietary thing that isn’t supported by standard USB downward facing ports.

- Comment on Super hero movies should have more scenes of them accidentally maiming people just because of the sheer amount of power they weild. 1 month ago:
It always bugged me how in Man of Steel, Superman has to deal with the moral quandary of breaking the bad guy’s neck at the cost of vaporizing a family.
Like they spent the previous 20 minutes punching each other through buildings. No way that was the first family they killed.
- Comment on When can we expect 500TB drives to be available? 1 month ago:
Moore’s law factored in cost, not just what was physically possible.
The complexity for minimum component costs has increased at a rate of roughly a factor of two per year. Certainly over the short term this rate can be expected to continue, if not to increase. Over the longer term, the rate of increase is a bit more uncertain, although there is no reason to believe it will not remain nearly constant for at least 10 years.

- Comment on All Of Apple’s Foldable iPhone Prototypes Have Visible Creases, Which May Explain The Company’s Apprehension Towards A Launch 1 month ago:
What I don’t understand is why nobody makes a foldable phone where it’s just two flat screens with an invisible bezel along one edge so they fit seamlessly together when fully opened.
It’s not like there’s a use case where you operate the phone half unfolded and require both halves of the screen to be seamlessly connected.
If the flexing feature wasn’t a gimmick and there was an actual use case for a foldable pocket iPad, someone would have released a phone like the Kyocera Echo en.wikipedia.org/wiki/Kyocera_Echo to commercial success.

- Comment on What’s the best method for documenting a ROM that I’m reverse-engineering? 1 month ago:
Yeah, it was a budget portable device released in 1995 running a processor from 1984. I think it was just written in straight assembly. I’ve even found some unreachable code snippets in the assembly that print debug messages which confirm that theory.
- Comment on What’s the best method for documenting a ROM that I’m reverse-engineering? 1 month ago:
Thanks for the response!
I think the issue is that the “structured programming equivalent” is just a really, really long function that’s not any easier to read.

Yeah, the GVDCVG is ground, voltage, data, and clock. My board is going to sit between this ribbon cable and the part that normally connects there.
You do make a good point though. I was hoping for an elegant solution where this ribbon cable was the only connected component, but there’s a large exposed voltage testpoint exposed nearby. It’s 1.5mm wide and 3mm from the board edge. I bet I can find a miniature allegator clip or some other way to connect to that.

Everyone needs to start somewhere. The goal of this project is for an everyman to repurpose some e-waste. Hoping to maybe inspire a few people to learn more.

The circuit in question draws a decent amount of current (probably like 100mA or so), so I thought it better to short the signal line than try to power it directly.
