  1. professional fridge temperature probes are generally in a small jar of oil to eliminate the problem with being too responsive to brief temperature spikes. (My experience is with medication fridges, and the vial of oil is about the same size as the vials of medication that are being monitored)

  2. Despite owning and using one of these for a long time, I never realized you could stack more than a single record up there. I always put one on the bottom, and one on the top of the spindle, and assumed that's all it could handle. I never tried a stack! You learn something every day!

  3. I do clean the filter on occasion, it never seems to be that bad. My issue is that it also doesn't seem that effective. I've had a handful of times where large debris has gotten past it and clogged the pump. I don't understand how this happens, but it is quite problematic. I've really been doing my best to keep things like vegetable bits out of the dishwasher, because they seem to be the things that manage to get past the filter yet not dissolve.

  5. My experience is pretty much the opposite, I had tons of those bulbs, but they had extremely short lifespans, way shorter than incandescent, and were ridiculously expensive. I did like the color rendering, but any hope of saving money over the long run vanished really quickly when I discovered how short their lifespan was.

  6. I need to disagree with a fair amount of this speaking as a Tesla driver: I live somewhere where almost every workplace has "level 1 charging" because we get real winter, so most workplaces have block heater outlets in the parking lot. Nobody will use them because it's too inconvenient to lug your cable around instead of just leaving it in your garage, and because it's significantly less efficient than Level 2, and because it adds so little range it's not worth bothering. Additionally, because EVs actively heat or cool their batteries before charging, that conditioning can use up all of the level 1 current available, leaving none for charging when it's really cold or really hot out. There is no point to any business installing level 1. Nobody will use it. It's not even worth plugging in unless I plan to be there at least 24 hours, probably more, and the weather is decent. Level 2 charging is appropriate for homes. If you've spent tens of thousands of dollars on a car (or over a hundred thousand!) you can spend a couple hundred to get an outlet in your garage. You'll be thankful you did. Level 2 charging is also appropriate for hotels as you'll be there overnight to charge. Nobody else should waste their time installing level 2. It's useless at a restaurant, or theatre, or grocery store. I'm not at those places long enough for a level 2 charger to give me enough range to matter, and most of the time I'm not far from home anyway, so it's not worth the hassle. Level 3 charging. Here I'm in complete agreement. I'm surprised no national chain restaurant has announced plans to equip all their highway locations with Level 3 charging. Even if they require payment for charging, it would still be a great draw for EV drivers. Overall infrastructure: We DO need more infrastructure, but we don't need more Level 1 and 2, we are way over saturated on those (except in apartment buildings where these are legitimate concerns) What we need is Level 3. Talking about the "average" commute is pointless, that's covered from your garage at home. But we can't ignore roadtrips. It may only be a few times a year, but dismissing the need does a real disservice to EV adoption. Level 3 chargers are the only ones that enable long distance driving. Those need to be more common, and so far, they just aren't. Sure Tesla has tried, but their network has a lot of very noticeable holes in it yet, and nobody else is even making an effort.

  7. Dishwashers are actually very light. Especially the all plastic ones. People expect weight just due to the size, but it's mostly just air, the heaviest part is the motors, but they aren't all that big/heavy really.

  8. Most of the time we use a French press, coupled with a real kettle. However when we do use our drip machine, it has an insulated carafe. If you come back later for another cup it can keep that coffee warm pretty much all day. It's actually somewhat genius, and I'm not sure why more of them are built that way! (Our coffee maker does not have a hot plate on the bottom, just the insulated carafe)

  9. Interesting, I just double checked the manual for my Bosch dishwasher also in North America, and it says to hook it up to the hot water, specifically 49° c or 120° f

  10. As part of a local government program, I had the energy efficiency of my home audited. According to that audit, the design heating load for my home is 11.25 kilowatts, according to the same audit, the output of my existing heating system is 12.5 kW, I'll consider that close enough! A note about smart thermostats, I'm glad yours provides useful statistics, mine does not. In theory I have the same data you do, however I have found way too many times when the thermostat shows as heating while the furnace is off, or times when the furnace is running, but the thermostat does not show heating. I don't know why mine is so inaccurate, but it is a little frustrating!

  11.  @flatterkatz  I actually have the same one he shows in this video, and I know I'm locking it into place correctly. My suspicion is that the bottom of it doesn't actually fully sit flush in the bottom of the well, allowing some debris to go down the center, and then get under the bottom and bypass the filter.

  12. The pre-wash is the gateway drug. I initially convinced my wife to get gel (powders just aren't available around here) for the pre-wash while continuing to use tabs for the main wash. When we ran out of tabs, I just started using the gel for both and we never went back.

  13. Mercedes did that for a while too, in fact when my 1983 mercedes' relay died, I had trouble describing it to the parts guy at mercedes, and he thought I wanted a new sound generator. In my car it was a relay, so it made a ticking sound, and no separate sound generator existed, but he couldn't grasp the older technology and insisted that cars had a micro-controller for the flashing, and a sound generator for the noise. These days it's all done through the stereo. If I reboot my infotainment system while the turn signal is flashing, the sound stops until the infotainment system has finished booting up again.

  14. This video is hilariously timely. I had never seen one of these before yesterday when my friend gave his old one to my 5 year old daughter. (ours is grey instead of yellow) Despite the fact that she has access to an actual modern tablet, she loves this thing.

  15. The reason they think you are insane, is because you are literally paying a whole bunch of money to replace perfectly good appliances, just so that you can INCREASE your monthly energy bills. There is simply no good reason for anyone to do such a thing.

  16. "I don't want you to leave money on the table" Is that some form of sick joke? This whole video is all about how you should pay tens of thousands of dollars, to throw out perfectly good appliances, just so that you can have a HIGHER monthly utility bill! And then you have the gall to talk about "money on the table"? If this had anything to do with money, you'd be talking about how to replace electric heat/clothes dryers/stoves with their cheaper natural gas counterparts which cost 1/5th as much per month to run!

  17. I've honestly never seen a toaster oven without that warning, and I've seen a lot of toaster ovens.

  18.  @manitoba-op4jx  current LEDs are much more consistent, they all consistently fail in a couple of years.

  19.  @mmmhorsesteaks  as an end consumer, I don't care what destroys it, I care that it didn't last. Yes those bulbs do get too hot to touch, which may be why they burn out so quickly.

  20. Mostly the sync on emergency lighting is to sync with other bulbs in the same vehicle. It used to be that emergency lights all were flashed by a central control module, but now they're mostly all flashed directly at the bulb, so need a sync wire to other bulbs if you want any form of coherent or coordinated pattern. That's also why you see some vehicles where they aren't at all synced (usually maintenance vehicles with amber lights, as those tend to be the ones cutting corners on installation, organizations with emergency vehicles tend to be willing to spend more money to install properly). What's more interesting is the ones that design flash patterns that ensure that there's never a time when no bulb is lit. This is because cameras are really good at capturing emergency vehicles looking like no lights are on, even when responding hot. (people love posting pictures of cop cars running red lights for instance) and although our eyes see lots of light, camera shutters are so fast they often land in the gaps.

  21. Because too many humans don't know how to human.

  22. That only worked on about 80-90% of drives. I had a few that would never shut no matter how much you pushed on the tray, and you had to use the button.

  23. Traffic lights are bought by government agencies. Government agencies are not cost conscious. Manufacturers put in more expensive components.

  24. This varies wildly depending on the LED bulb. Cheap bulbs are definitely problematic. The Phillips one he showed at the start is actually really good, of course the issue with it, and all LED bulbs I found, is that their lifespan is significantly shorter than incandescent, meaning that you never make up with savings in electricity, the increased cost of the bulb.

  25. For most people, good luck finding something with phosphates these days, they've been removed from everything. My old dishwasher worked fine up until phosphates were removed, and then dishes just weren't clean anymore.

  26. See his video about "but sometimes". And just brush your car off!!!!!

  27. Automotive manufacturers in north america also made sure that parking lights are unusable, they turn on all 4 lights, and often the dash lights too, to drain as much of your battery as quickly as possible. contrast to european "standing lights" which are only on one side of the car, and no other lights, to allow you some hope of starting the car again if you left them on for a couple of hours. Parking lights are another one of those things that sounded like a good idea to people writing the laws, but has been implemented in a way so as to actually be dangerous (thinking your headlights are on when it's just your parking lights) while not being at all useful for the purpose they were designed for (making your car visible when parked on the side of the road)

  28. Having owned and driven a couple of japanese vehicles in my past, the direction of the turn signals was never an issue, hitting the wiper stalk or the shift lever instead of the turn signals because I used the wrong hand... that happened.

  29.  @KevinSauer  Even if you're waiting until they break (which is actually not what he advocates for in this video), why would you intentionally buy appliances that cost 5 times as much to operate? Electricity is "shockingly" expensive when compared to cheap natural gas.

  30. Engineers from many decades ago: okay, I need to figure out the exact amount of heat that will be generated in this by metallic strip, the exact amount that it will curve based on that heating, and therefore the exact distance that I need to place the other contact from it at each of the different power outputs. Engineers from today: computer chip, done.

  31. Thank you for finally explaining what the actual difference is between a contactor and a relay. It's something I've asked people several times before, and never been able to get a straight answer.

  32. Unlikely, the bimetallic strips aren't durable enough. You'd likely see the capacitor and relay version on older ones, and a circuit board in newer ones. Keep in mind that people designing traffic signals are designing for government buyers, as such, there is no attempt at cutting costs.
    2
  33.  @jennawoodbury5999  The package will be identical for the reasons you mention, but the internals of th component may not be. That said, either way it won't likely be bimetallic because they just don't last long enough, and because of the delayed start he shows here. Those were always a compromise for cost vs the other design.

  34. As you want to be able to track motion in multiple axis, I strongly suspect these are more than two crystals, so that you can capture not just side to side, but vertical as well

  35. That Ford signal stalk is the bane of my existence! I hate it with a passion! I can't tell if I'm using the momentary flash, or the fully engaged signal. Do like every other car and click into place when engaged so I know! Did nobody at Ford ever try driving their own vehicles? or look at human interface design factors? That thing's a disaster! As for silent, something in that truck was broken, because it needs to make noise by law.

  36. Interesting info about low-e windows. I was told when I got mine that the coating was designed to only block IR that came from high angles, and not from low angles, which would solve your winter/summer issue without overhangs. I'll admit though that I've never tested it, and it's quite possible it was all marketing BS rather than actual fact.

  38. I would say that after your first video I did use up the last of my pods with a powder pre-wash, Haven't bought a pod since.

  40. You are definitely my kind of crazy! My family has to drag me out of the light bulb section of any store. So several of your points really rang home. Also, you are objectively right about the colors, pink and purple definitely do not belong on a Christmas light strand!

  41. If that were the case, you'd be better off with a liquid/powder version of the same thing so you could get that stronger cleaning in both pre-wash and main cycles.

  42. In relation to your latch comment about manual overrides, newer Tesla vehicles have a manual override to release the charge cord, however the older vehicles do not. Which means my car, a 2014, cannot manually be disengaged from the plug if there are issues, it can get very, interesting, at times.

  43. headlights are supposed to be on separate fuses? my previous car certainly didn't know that! the wire went from the fusebox to the headlight switch, then to the left headlight, and across the front of the car to the right headlight. no separate fuse or wiring!

  44. super fast is either a burnt out bulb, or someone swapped to LED without swapping the module or adding resistors. And as shown in this video, no modern car uses analog circuits anymore.

  45. And yet, there are multiple different versions of them. My parents have... or had?... one that used an actual ratchet mechanism in the turning. So apparently either it was invented multiple times, or someone improved on the design (not certain the ratchet version is the improvement, seems more complicated than this one)

  46. What killed the changer was really a combination of things: with LP albums at 22 minutes per side instead of the single song 78s, they just weren't seen as being as essential, additionally other technologies were starting to appear on the scene (8 track and cassette) so people were no longer using the records exclusively and needed more space for other components. The newer formats also served to transition records from something everyone listened to, to something that audiophiles and collectors used, neither one being a group which would dare use a changer. The changers were a great technology and I remember using them myself. That said, I still learned something in this video, I somehow thought you were limited to 2 records, not a full stack. I always placed one on the table and manually started it, and then had the second up top to change. I had always assumed that if you had more records up top they would all fall at once. I was wrong!

  47. What I learned from this video? There's more than one version of what I thought were the same sprinkler. My parents' one uses an actual ratchet mechanism in the turning. The propulsion is still done by the arm as in this version, but it doesn't just use friction to limit the movement. it's an actual ratchet ring all the way around the neck of the sprinkler, when it hits reverse it disables the ratchet for the spin the other way. For me. I just use one of those flat hoses with the pinholes down the length...

  48. Some use sound generators separate from the stereo, especially if they think people may use an aftermarket stereo in their vehicles.

  49. I had many of those Philips bulbs, ridiculously short lifespan. They've all burned out now. But realistically, I've never found any LED bulb that will last anywhere near the claimed lifespan. From a pure financial sense, incandescent bulbs are significantly better. They last much longer than LEDs do, and cost next to nothing, the shortened lifespan of LEDs in comparison means that you never recoup the extra purchase price through electricity savings over the life of the bulb.

  50.  @mmmhorsesteaks  The drivers are definitely the weak spot. Wiring has been inspected and certified several times, main entrance cable and panel has been upgraded. Power in my area is known for reliability as generation is close to the end user on a stable grid. The philips bulbs as pictured at the start of this video were really bad and have almost all failed at this point, I also have ceiling fixtures that have non-replacable LED panels, several LED light tubes (replace flourescent tubes) and many other LED bulbs, I have tried ones from pretty much every major brand. I replace a bulb, tube, or integrated fixture a few times a year. The only filament bulb I have left is the one in the oven, and after 12 years I finally had to replace that one this past month. I wish I could get that kind of life from an LED! As it stands, with the cost of LED bulbs, and the ridiculously short lifespans, they are both a financial, and environmental, disaster. That said, the sucker in me keeps buying them because they're "Supposed" to last so much longer that I should be saving on both purchase price and electricity use. I just wish it were actually true.
