  3. I've been watching this channel for at least 8 years. It might've been your vid on LED traffic lights that first got my attention (algorithms in action)! Never would've expected this video from my favourite feel-good-vintage-cozy-nerdstalgic channel, but damn if it the didn't hit the nail on the head. Genuinely, this is a huge ongoing concern of mine—increasingly so—for years now. Thanks for bringing this up with the regular brilliant articulation and humour. Looking forward to that dive into WPC-era pinball as previously teased! Massive respect from Canada 🇨🇦

  4. Here’s a better metaphor: Imagine having a phone that runs on a gasoline motor. Next, imagine that everytime you want to charge your phone, you had to got to a gas station to properly supply it with fuel. That is our current system with cars. But imagine a battery powered phone that you can simply be charged at home overnight, so that you will only be draining it when you actually use it in the day.

  5. “LED’s use of single wavelengths is why the light looks like crap” finally someone explained to me why I hate most LED lights in a way that makes sense to me!

  6. The fact that there is any controversy over improving the safety or just reducing the ambiguity of an activity that so many people risk their lives doing every day is so baffling. The amount of negative comments and dislikes on this video is disappointing.

  10. I think what often gets lost in EV discussions, which you somewhat address here, is that EVs or any new technology doesn’t have to be perfect. It only has to be *better*. In my experience, people who are resistant to EVs focus on the unique aspects of operating an EV without actually comparing it to the effort of operating an ICE vehicle (getting gas, maintenance, longevity, etc).

  11. Ok, a few comments: I got a slightly smaller version of this same product at Costco for $1600 -- which was the upper limit on what I'd pay. It has four trays that are a bit slimmer, but more than enough for my needs. Your opening statement about the 'preppers' and the rabbit hole of hell about freeze drying on YouTube is PRECISELY what I said a few weeks ago to some people. OMFG. You nailed that one. Things I've found: - Pineapple - surprisingly good - Berries - awesome - lowfat yogurt - OMFG SO BAD I WANNA DIE - and even worse, don't mix with water! - caramels - BLEW UP SO BIG - but quite interesting - ice cream - awesomesauce!

  12. I've been watching your content for at least a year, and became an electrician along the way. I'm thrilled that your content is not only still amusing, but actually useful to my work. Cheers, and thanks for making it

  14. Even if it succeeded past these two trial periods I guarantee it would have been a PR nightmare. How often do you read the interior of DVD/Bluray packaging? You probably don't. Now imaging being say, a parent thinking you just snagged a cheap DVD for you kid in a "dixie pack", you get home and let your kid watch it. Then a day later your kid wants to watch the movie again, they pop it in, then com running to you crying that the movie doesn't work anymore, especially since nowhere on the outside of the package did it mention that the DVD would self destruct. It's perfect that it's round and metallic like a landmine because this thing would be a nightmare for anyone unfortunate enough to work in that customer service department, and probably a lawsuit waiting to happen. Not to mention now you can get some pretty good bargain bin movies for five bucks a pop now anyway.

  15. "Assuming you have some storage" Fun fact. You can use a freezer AS electric storage. If when energy production is high you over cool the freezer, that is make it even colder than normal, then when production drops off you can allow the freezer to warm back up to normal temperature and not use the heat pump during that time. That essentially means the running of the heat pump later came be done earlier, which is equivalent to storing the power to use later. There are some huge industrial freezers that do this to save energy by working overtime when power is cheap and demand is low to help reduce grid stress and "store" power for later.

  16. 3:13 Yes, all of you from PAL regions have actually been watching our movies in the wrong pitch. If you've searched for clips from your favorite movies and heard them with a lower pitch, you're actually hearing them in the correct pitch.

  17. I'm imagining a wick that can traverse up and down with the aid of a pontoon float on its sides... Get that super duper tank capacity and no pump required and no drizzle sound. The wick could float to the top when the tank is full then slowly drop down (always keeping its bottom 1" or 2" submerged) totally silently 😁👍 Loved this video!

  20. You say you watch the comments after upload so now is the best time to say thank you for all this content. I always look forward to it!

  21. I think they look quite good, I'm a fan of how they fade in and out as well when changing numbers.

  22. I'd like to add that having any kind of microelectronics circuit hardwired into your house increases the relevance of a whole house surge suppressor. At my last house, electronic things would often get fried due to noise and swings in the mains power. I finally installed a monitor to prove my power quality was terrible. It doesn't take much to fry an LED board. And during a thunderstorm, even a strike a mile away can raise your voltage to levels unkind to electronics. At least with screw-in LED bulbs, you can CHANGE THEM when they fry.

  23. Hi! we were just sent a link to your new video! We're presently a (small) 2-person business (recently from CHICAGO), and got in this because of the same reasons you elaborate on here! We'd tried sending you a few messages last year, but I think they got lost in the pile you must receive! We'd LOVE to chat sometime! info@tru-tone.com

  24. It is awesome to learn that the filament style LED bulbs potentially last longer... in addition to simply looking so much cooler* than many of the alternatives! * The good kind of cool 🕶️ not the bad kind of cool ❄️ as far as lighting is concerned. 😉

  25. For the background of the design choices for this camera, look up the designer: Yoshihisa Maitani. He was a passionate photographer and felt that the half frame format let him take twice as many pictures for the same cost. He also designed other influential Olympus cameras including the OM1 and the XA series.

  26. My pleasure!

  27. I live in MA and I've been on a plan with my power company where they can change the temperature remotely for my AC. They do exactly what you suggest - set the temperature lower in the morning and then raise it in the afternoon to lessen load. I can always override and I still get my incentive if I override less than 25% of the time.

  28. That tracking mechanism is devilishly simple.

  29. Really happy you included the part about building resilience through communities at the end -- an important and consistently overlooked aspect of how we approach challenges throughout the U.S.

  30. Another great video. Congratulations on 100k, it's well deserved.

  31. It's worth mentioning that vinyl stereo is in a way a bit more limited than stereo on another medium like tape or CD. For example, there's a limit to how loud you can have a panned sound. If you have a really loud bass drum hit in just one of the channels, you risk launching the stylus out of the groove. One of the things I was told when it comes to dance music production is that, for vinyl mastering, you absolutely must not pan your kick drum or bassline. CD doesn't have this restriction.

  32. I prefer for the brake and indicators to be separate, it eliminates ambiguity as you say.

  33. "The first commercially successful game console to use the compact disc..." What a polite way to say "haha suck it NEC, Sega, Amiga CDTV and 3D0".

  34. I bought one of those because I didn't want to have to use the shared fridge in the office in a place where I worked, it was not intended to do anything more than just keep the lunch that I'd already packed cool for a while. I think I would have done just as well by getting a portable cooler and chucking a couple ice bricks in each morning. That's what I've been doing now that I have delivery work and honestly it is the same if not cooler by lunch time.

  35. As someone from Europe, where light switch outlets are virtually unknown, I always wondered why in movies when people switch the lights on all desk lamps and floor lamps switch on too. Now I know!

  36. This was definitely interesting. Especially the shot with the suddenly-red etch-a-sketch. I now understand the importance of CRI in a way I never have before. Alec, I think you should take a look at my video "How the hell does color correction work??" ... specifically, the Google Doc that is linked to in the description. (I'd link it here, but then my comment will get stuck in the spam filter.) Most of the information on that document was provided by my subscribers - and it's info that I hadn't been able to find anywhere else. I also have another video coming soon about monitor color profiles. They are far more tricky to deal with than anyone realizes...
    211
  37. I would like to add a correction, or rather an improvement to your explanation. Around 5:10, you said former filters were not very precise. Precision in filters is given by the Q factor (blablabla you can search for it). Now, Q = (Frequency / Bandwidth). As the frequency the filter is tuned to increases, so does que the bandwidth it lets pass through. The real problem with this tuning filter is that you cannot have the same bandwidth throughout the whole spectrum, so you would have higher frequency stations having their signals mixed up under the bigger bandwidth of the filter. So yes, you are partially correct, they were not very precise, but it might would be better to say that their precision varied with the frequency. I love your channel, you seem to be so passionate about older technology! People were really clever back in the analog days. None of that microcontroller gibberish!

  38. The only thing I felt was absent was the efficiency loss from 120V versus 240V. The overhead you mentioned is one part of it, but efficiency is the other half of the story. The higher the current, the less is lost. It seems like the difference is somewhere in the realm of 5-10%, which is not nothing but still fairly minor compared to the cost of getting a L2 EVSE wired up.

  39. A tangent... a 100% accepted and demanded tangent!

  40. Also, i think that turn-style electric switch could be traced to gas valves as well.

  41. I wish you had mentioned how the scientific community found out you could make graphene supercapacitors and other graphene related experiments with the help of a lightscribe writer. They take a solution of "graphite oxide" or a super sonic mix of graphite and water. Glue a cutout sheet of plastic or kapton cut to the size of the disk with the barcode exposed. Then after some dry time put the disk into the writer to activate the solution. Apparently the laser burns at just the right temp to align the graphite solution into graphene.

  42. 0:40 “Very simple explanation” Proceeds to make 37 minute video that I will watch

  43. I'm amazed how many people entirely miss the paradigm shift that is being discussed. The point is that EVs are fundamentally different in terms of how you utilize them. And everyone agrees that there are challenges and there are applications where they won't work, but my Jetta won't move a queen size bed, either. So there's that argument down the tube. I fear for people with the attitude of "because it's this way now it will be this way forever."

  44. "For physics reasons im not quite sure of" Physicist here! There are two reasons to keep the walls of the freeze dryer frozen. First is a technical limitations of many vacuum pumps, generally speaking vacuum pumps don't respond well to water vapor so we want to keep it out. The second reason is that when you are heating up the solid water it is evaporating at quite a high rate. Even at atmospheric pressure going from solid to liquid is a roughly 700x volume increase. Additionally, at the low pressures required for freeze drying the efficency of vacuum pumps drops dramatically (applied science does an excellent explanation of this in his video on a glass diffusion pump) so they can't pump nearly enough water vapor from the chamber to keep the pressure down. Thanks to the refrigeration cycle it is very easy to make a really cold surface. When the water molecules run into the cold walls they loose energy and end up sticking together, forming ice in the process.

  46. When talking about modal dispersion, and TIR, you missed two points. One, is that if there are any bends in the cable, TIR applies anyway; that's the only reason that you can get light on the other end, even if your cable is coiled several times over. The other, is that almost all modal dispersion is almost completely remedied by using lasers in place of LEDs, alongside using higher quality fiber strands with less imperfections. As well as using single mode fiber cabling in multi-mode systems.You did mention that lasers make fiber faster, but you didn't provide the why, even though you explained the how beforehand. Another thing to consider, is that fiber doesn't handle kinking very well. You can staple a CAT5e cable to a wall, and crush it into a kink, or bend it 180° to where unbending gives it a permanent bulge, and it will still have a chance of functioning, even if not ideal. But Fiber will break instantly, immediately, and almost irreparably the moment it gets in any of these tough situations, unless the sleeving is reinforced. And sleeve reinforcements only help with some of the problems. It's probably impossible to fully cover every aspect properly, without making a heavily edited three hour document with multiple takes for each section.

  48. I switched to dish powder a few years ago after watching your previous video, and I couldn't be happier. Less packaging waste, perfectly clean dishes and I've saved a couple hundred Canadian dollars on powder vs. tabs over this time. Thank you @TechnologyConnections for saving me hundreds of dollars, which I can now spend on Super Thanks.

  49. You should do a show on all the subchannels in FM radio. SCA at 67khz, RDS at 57khz.... heck for that matter, /all/ of the encoding in stereo FM.... phase locked pilot tone, sca, rds, muzak, WEFAX, and digital FM radio.... digital traffic info.... all of those individual services in 200khz of bandwidth.
