I've seen some thick red bars in the old days, I wonder what those elements looked like bare?

Hey kids, it's Howdy Duty time! Props on your mad rehearsal skills. ;^)

Forever hopeful for a video on induction ranges. I'd love to see the inside of a Vollrath Mirage Pro or Hatco PC1.

Love your videos. This one felt extremely remedial. I understand you're looking to appeal to a somewhat broader audience, but this particular one felt like it ventured into a padding runtime.

That was nauseatingly repetitive

how about i dont want my car to make noise? I can turn the headlights off when i want. I can always honk the horn if i want people behind me to pay attention before i move.

This is why cast iron cooks so much nicer. Its lathe mass acts as a heat buffer.

it's just badly designed

time for a video on induction stoves me thinks

PWM anyone?

Naming is funny. My stove has a "simmer zone" - 1 area that has a unique control that isnt a simmerstat. I suspect its just doing fast pwm with a zero crossing triac.

1950’s tech 😂

Ive noticed that microwaves also do this pattern of on and off when you change the power output to under 100%, basically doing this function of the simmerstat, though i do not know what components make this happen.

I am on the UK. Our government gives us £7500 towards getting a heat pump fitted. Energy company Octopus Energy fit them at cost. I will only have to contribute £3000. This price includes everything required including 12 new radiators. They will then at my request disconnect me from mains gas. I generate electricity from 16 solar panels and have a home storage battery. My very small contribution to reduce carbon dioxide levels. Loved the video and it is brilliant to put out this message worldwide although some countries are way ahead of us.

You missed a golden opportunity to say simmer down at 30:20

I don't think my stove has one of these. Instead, each hob has three elements of different sizes, and offers different power levels by turning on different combinations of the elements. It only offers a discrete set of power levels rather than a continuous range.

A nice refreshing video

It's quite incredible engineers of previous turn of the centuries were coming up with using geometry and physical principles. If we were to reinvent it today we'd drop in some bloated microcontoller, 50 years ago we'd make it with 555, mosfet, and a variable resistor, and for the latter one I honestly don't know whether that or the simmerstat would be cheaper.

The amusing part is that I've only ever used gas stoves all my life. And yet I enjoy learning about these alien cooking machines and their simmerstats XD

My grandmother had a 500 she rented until ~'03, and I've always wondered how many other people were still doing that at that time.

12:12 😂

I can’t stand them being like that (ground up)i changed all the ones in my house. Also all the screws need to be parallel.

Super 8 home movie film was even more fragile, and you had to cross your fingers when trying to auto load the projector that it would.not jam up. Technology has come a long way!

I almost cut my fingers off in an old 1940s industrial fan. I was playing drums and it was behind me and had not thought that about how it was one of those open guards and my fingers went right in. Still have scars. Also youre holding that old fan and its likely a brush motor dont do that! Only do that if its a brushless motor unless you wanna burn up the windings!

I have a fan that has off and then low med and high

There is yet one more problem and that has to do with the one pedal driving itself where the gas pedal functions as both a gas pedal and a brake pedal (regenerative). One pedal driving conditions your brain to use the gas pedal as a brake pedal by lifting your foot off the gas pedal but your natural instinct (also conditioned by our past driving experience knowledge of 100 years) is to slamm the brake pedal instinctively during emergency stop. There is a conflict going on in the brain during emergency stop because your brain wants to slamm the brake pedal, but you have almost forgotten that there is a separate brake pedal due to constant one pedal driving. So what do you end up slamming down? You end up slamming down the accelerator/gas pedal instead with totally opposite result and a disastrous accident. So what is the solution? It has always been there untill the one pedal driving came along. Bring back the regenerative braking function to the first part of your dedicated brake pedal itself rather than the gas pedal. That way we will lose one pedal driving mode but we will have more safety and a preserved regenerative braking with active brake lights.

6:05 very nice way to say “USA and their colonies, occupied countries and client states”😂

I have never designed a simmer-stat, but have often thought to do so. It would use a zero-cross trigger device like a MOC3030, a suitably rated Triac, a super-cheap and simple microcontroller like a SILABS 8051 device. Manual temperature/power control by means of a simple potentiometer (or keypad entry if desired). Use full cycle switching control of the Triac in conjunction with a picket-fence on/off algorithm that gives a smooth, incremental power delivery from 0-127 cycles in 128 cycles (~2.1 second @60Hz or ~2.6 second @50Hz). Temperature sensing of the object being heated could be a problem (near-infra-red or thermocouple) but in reality is a viable option. If such sensing existed, it could be used to indicate a hot surface like on ceramic cook-tops but also be used to realize proportional control of the heating element, such that the element would run at full power (from cold) until it approached the desired temperature and then begins to fall back steadily until a consistent equilibrium is reached. In such a case the 0-100% simmer-stat control is transformed into a temperature control between specified design limits. [ A PID loop would be best, but how it would all come together is highly dependent on the thermal inertia of any such system as a whole ] A well engineered design could be a more reliable retro-fit substitute for the less than reliable variations of modern simmer-stats being manufactured today. They are using printed ink resistors as the bi-metallic heating element and are VERY crappy. Great idea, but very poor engineering in this one specific component. This is not the "simple" you are looking for Sir, but I do enjoy your zany narrative and can follow your chosen subjects in an informed way as a retired electronics design engineer. You have not been found wanting Sir.

Imagine, if that plane crashed when on final approach, and you were the only witness in the vicinity, you'd have to send your Beta tape to the NTSB for them to analyze the footage, and they'd be like : *What the F* ?? 😂

My furnace in my 1025 sq ft home with no basement is 100,000 BTUs. That seems like… a lot, right?

Man, that thing's so crude, it gets slapped by everything it meets. But it's really clever.

its like your living in my mind and decide to post a video when ever i have a how does this actually work lol. love your videos keep em coming

bet you a dollar the multi zone knobs on your stove have 3 separate bimetallic strips in differing tracks wired appropriately producing the desired effect!

I love how seemingly synchronized that light is to when he talks 😂

is there some mechanism to quickly break the circuit? i'd be curious to know if there's a lot of arcing going on inside every time the connection is made and broken damnit every time i make a comment i realize if i just wait a little longer you touch on it LOL

The effort you put into making complicated topics like thermodynamics approachable and clear does not go unnoticed. Some of the best scicomm out there, this channel.

Why would anybody have a stove top that's neither gas nor induction?

4:20 Blaze it.

And that children is why Grampa prefers to cook on a gas stove.

bimetalic strip is also used for mechanic tasks like controlling air flow for idle valve in my 93' Brazilian Chevrolet Kadett E. The strip opens the airflow a bit when the engine is cold, this airflow bypass the butterfly so engine stays around 1500 RPM for 2 minutes. The heat of the engine warms up the valve, but it's not enough so they also put a resistance to help it warms quicker. (very important in highway where the cool air would NEVER allow it to happens). Lots of things can go wrong, but when correctly adjusted it can work decently, and actually better than electronically controlled on-off simple solenoids. Of course now-days cars use some even better solutions like the stepper motor in electronic throttle itself.

pretty amazing that i can watch this for free on youtube

That literally just looks like a regular normal sized fridge to me…

PWM shows on off cycles. Duty cycle shows length of on and off time. You had a long winded way of saying that but yes i agree they are different.

Meanwhile, I'm over here combining pulse width modulation, pulse frequency modulation, delta-sigma modulation, multi-stage power regulation circuits, dynamic underclocking, and microsleep optimizations... just to make LEDs dim smoothly and efficiently across as wide an output range as possible on cheap hardware.

I do wonder how much would it cost with a fancy variac or other method that doesn't pulse. There's something bothersome, at least for me, of a heating element pulsing on and off rather than providing continous low power heat. I disliked seeing what I'm cooking heat up and cool down as it pulsed. If I'm trying to simmer, I much rather have a continous low power output, than blasting 3KWs on an off. I will add, now I'm invisioning a variable diameter stovetop, by adding the recistances cm by cm, for example. Fancy! Expensive too.

@3:41 Duty Cycle Control = Me Deciding When To Poop My Pants

Ah yes, a video about my arch nemesis (I am a professional cook so gas/induction fanboy, get the heated coil garbage outta my house lmao)

Now waiting for Label Flash.
