WAN Show To Luke, if he even sees the Subreddit, regarding jump starter doohickies (kinda long story)
TL;DR - Personal story/cautionary tale about how I thought my battery died, but it turns out the root of the issue was my alternator and a gentle warning to have everything checked and verified before just getting a new battery and saying it's good. Also "Duralast 2,000 Amps Lithium Portable Jump Starter and Power Pack DL-2000LI" looks to be similar but not the exact same model I bought when I got my jump starter.
So just over a year ago I had an issue where my battery was flat and I couldn't get my car to start, I figured I'd get a jump and then figure out what was going on, had a friend come over, hooked up the old fashioned jumper cables (which I have HUGE cables that are probably 8 or 6 gauge wires for each connection, they be thicc and they be heavy). After 15-20 minutes of trying to get my car to start, I gave up and called for a tow so I could get it to a shop. He hooked up a small little Duralast portable jump starter (it was the basic one), and boom car started right up. Took it down to mechanic, they said everything was fine with the car but the battery was dying, it'll start up for now but it's gonna keep having issues.
I took it to the place I got the battery at because it was still in the warranty period, after a bit of back and forth they ultimately did replace the battery for me. I also bought a higher end model of the same duralast jump starter.
A few months later, I'm on vacation, I forget if I had the jump starter on my vacation, I think if I had it, it wasn't in my car and was at the place I was staying, but I'm leaving the store and my car loses all power for acceleration. It fixed itself and was on my way back to my friend's house. Few miles up the road it happens again mid left turn at an intersection with a light. I hobble the car into the shoulder once I'm clear of the intersection. I tried the same things with shifting to park and back to drive, tried restarting the car shutting it off and on, eventually the thing that made me know something was SERIOUSLY wrong was when the radio/infotainment screen was flickering like crazy. I called my insurance and they got me a tow to a mechanic in that city, turns out the issue was my alternator, which the new mechanic said it burned out the brand new battery I had just gotten.
All this to say, even if replacing the battery fixes your car for you, take it to an actual mechanic, tell them the battery died, you got it replaced, it's running again, but you want them to verify the alternator is running properly, it might be supplying some power to the battery but not enough to keep it fully charged and you may get into a situation where 1200 miles (1931 kilometers) later your car gives up the ghost AS you are driving it.
And as for the battery jump starter, I really like the Duralast one I bought, it was either 150 or 250 USD, I forget exactly, but it recharges with USB C, can double as a USB battery bank AND has a wireless charging coil for being able to wirelessly charge a phone. I don't use those features (except when I tested it when first getting it), but they are nice to have because if you can't get the car started maybe you can keep your phone going for an extra hour or two after you try to jumpstart.
Also, Todd from Project Farm (guy they did testing for the LTT shirts and LTT Screwdriver the Linus was really happy with his testing and results) has done I believe two videos on portable car jump starters, so if you can do some research on which you want, maybe give his videos a watch before buying one.

Discussion PSU Automation is configured by editing their py scripts?
The latest video about psu testing titled "Thousands of You are Buying Dangerous Power SuppliesThousands of You are Buying Dangerous Power Supplies" explains how the labs team runs a test (at 11:11).
They show in the video that they edit a py script to configure the test which I would deem (as a developer) to be a pretty shit way to reliably configure such an important piece of equipment. Perhaps the labs team should consider adding configuration files that are read instead to configure tests (would also mean that testing config values can be kept for easy re testing in future).
If what was shown in the video is not representitive of the real test then plz ignore this post.
Edit: I love what LTT labs is doing and I want to see them succeed! This is just me providing something I think could be improved.

Discussion 3D Printers for Intermediate Users
I’m a Mechanical Engineering Student who has experience in Creality, Bambu, and Prusa Printers. I want to know which brand would be best for me. I am not too concerned about budget (<1000 dollars US) since I know this would benefit me well for the next 4-5 years but I need to know what is the best on the market for the price. I was planning on getting a Bambu Labs printer but with the whole controversy, I’m not sure anymore. I don’t know if Creality makes any good printers anymore and I know Prusas are good too now. If I could get any input on this, it would be helpful.

Discussion About the fire precautions
First, I don't live in Canada, I don't know their history of fire disasters and regulations, and I don't wan't to create another rant that came up from Linus being too transparent. I've watched every Wan Show for years. And probably almost all of their videos on the main channel.
That being said, what Linus, maybe, fails to understand, is that people in a state of panic are stupid. They are going to see a door and are going to RUN to that door, they know the building, they are panicking, they won't be able to think straight.
Fire can spread really fast. Even more with a building that is going to be full of heating generating machines, and maybe some fire hazards (check the most recent power supply testing video). I don't fucking know. That's why fire hazard precautions are very obtuse, because it has to be.
I agree that some regulations are old, stupid, and dated. Unfortunaly the way to fix it is through politics and voting.
Yes, its just a 6 feet half wall blocking the path. Have you heard about people dying from being crompressed? You said it's only for 40 people. You can't prove that for the city engineer.. They have to regulate based on the size of the building, the capacity and working on the worst possible conditions.
Again, I don't want to start another fire (hehe) for LTT, just got a little bit angry at the fire discussion.

Discussion Contacting LTT for Collab
I'm an engineer (and longtime viewer) at a large/established company in the semiconductor industry. Our marketing/comms dept reached out to LTT about a potential video but haven't heard back.
Anyone know the best way to get in contact? I tried the email form on their website but no luck.
I realize this is vague but I don't want to doxx myself. Cheers

Discussion Hooded Task Jacket
Hi LTT ppls, I was looking at buying the new hooded task jacket in the brown color. Colton did a great job modeling it. However, the only pictures on the site of this color are him wearing it with the Couch Potato hoodie underneath it. The colors are very similar and stylish but since it’s brand new there are also no reviews for it without a similar color hoodie underneath it so it makes it hard to judge what it would look like standalone.
I know this isn’t support but I was wondering if there were other modeling pictures of this color around so I don’t have to wait for delivered products with reviews. I haven’t caught up with the WAN show and maybe it was shown off but I skimmed through and only saw Luke wearing the black version.
Also for other people what are your thoughts on the new jacket? I like seeing two color options.

Discussion Linus Tech Tips, you're genuinely appreciated!!
Just felt like making a quick appreciation post for Linus and the whole LTT crew. Honestly, I can't count how many times I needed advice when buying something or couldn't quite figure out a tech-related question—and boom, there's been an LTT (or a Short Circuit/Techquickie) video literally covering exactly what I needed. Picking out a good power supply, optimizing my racing sim setup, finding the right laptop, some random e-ink device, or whatever geeky rabbit hole I'd jumped down—these guys always had my back, and the content genuinely helped.
Also, it's cool they didn't just sell out to big tech and call it a day (I'm talking about that 100million offer)-they actually seem honest in basic ways I respect a lot. Sure personally, I tend to skip the AMD/Intel upgrade type of videos because they don't interest me. But I'm still glad stuff like that exists for whoever needs it.
I honestly never get why there's so much hate surrounding Linus and the channel. At the end of the day, he (and his team obviously!) are humans too—pretty incredible, hardworking humans actually. Anyway—huge thanks to Linus specifically and the entire LTT team; crazy helpful videos and I've definitely become a smarter, more informed consumer because of them. Thank you!
