People more better at electronics than me; I have a sneaking suspicion this circuit is either simpler or more complicated than I’m making it out to be. The input, being labeled OSC, almost makes it seem like it’s counting clock cycles, and perhaps the pot varies the speed of an oscillator? But I don’t see anything that would create an oscillation (though I am certainly no expert). I’ve put a link to the datasheet in the description if you want to dive a little deeper.

[@wrentubes1886]

I know very little about electronics, but I had thought that toasters were all analog with no digital circuitry unless they were expensive ones. After all, they give the outward appearance of it, and I thought that computer chips hated the kind of temperatures found inside of toasters. Well, what do you know?

[@CaveyMoth]

I really want to know how the advanced (bagel) processing works, and why modern x86-based CPUs don't support (bagel) instruction sets.

[@tomaszbiskup891]

5:20 You basically show whole schematic and how it function on bottom of page. The 4 heater elements act for purpose of circuit as voltage divider cut the mains to 1/4. Then diode for rectify AC to DC and small electrolytic capacitor act as power supply for electromagnet. Then R1 C2 and zenner diode Z1 to cut and stabilize voltage to 3V to power the IC. The IC its just a counter, it count impulses generated at OSC pin, if it reach some value it changes state at OUT pin and turn off electromagnet. Now the OSC pin is oscillating with some frequency selected by resistor and potentiometer and capacitor C3. Maximum frequency (minimum time) is setup with value of R3, and minimum frequency (max time) by adding value of R3 and potentiometer W1. The oscilator probably works in this way: The capacitor is charging with current limited by R3 and W1. When voltage exceed threshold the OSC pin discharges capacitor and start over.

[@electronash]

6:07 The other-other clever part of modern toasters, is that the yellow wire is connected part-way along the heating element, which reduces the voltage to say 12 Volts. The diode then rectifies that to power the circuit, a bit like a tap on a transformer. ;) (obviously it's not isolated from the mains, but it doesn't matter as long as the outside controls are insulated.)

[@alloutofbubblegum8165]

@@TechnologyConnections Do you now know Kung Fu?

[@rjk7104]

Two important reasons for the way toasters are designed this way that were glossed over: 1. The dual contacts aren't really anything to do with reverse polarity, but rather to provide a safety margin in case one contact welds itself together (which is definitely a thing). This makes sure the heater turns off when it is supposed to, and the next cycle of the lever could unstick the first welded contact. 2. The electromagnet is also a safety feature because if there is a power outage, it will prevent the toaster from automatically coming back on when power is restored.

[@TechnologyConnections]

I won't argue against the redundancy they provide, but I still think they protect against a reverse-wired outlet. If the only break was on the hot side, and the plug were wired backwards, then sticking a knife down the toaster would potentially touch the wires which are now electrically live no matter if the toaster is on or off. With a break on the neutral side too, there's no risk of that possibility.

[@lionnelc13]

Many countries use non polarized plugs, and miswired outlets are awfully common everywhere. Also, some power systems doesn't use a neutral at all, they use 2 active phases instead A single contact would be very dangerous in all this cases, especially with this kind of heating elements, very easy to touch This is why it's to mandatory (mostly everywhere in the world) to have dual contact for main power switch. PS: In French safety regulations, the neutral is considered as an "active" conductor, requring the same precautions as a phase wire.

[@nimoy007]

I believe all parties here are correct.

[@rjk7104]

@@TechnologyConnections Good point, the nichrome is certainly conductive.

[@kissingfrogs]

@@TechnologyConnections As a kid, we would light a piece of paper off the toaster to ignite the gas stove. I regularly used foil backed paper from the likes of soup packets and one day I found myself thrown to the ground. I asked my brother who was buttering his toast at the time why he kicked me. He gave me an odd look and slowly it dawned on me what had happened. Sure enough I had shorted the nichrome wire against the frame and got a boot

[@ElectronicTonic156]

That yellow wire goes to a low voltage tap on the heating element, which acts as a voltage divider, suppling a low voltage to power the timing circuit and electromagnet. The voltage divider output, probably around 12 VAC, then goes thru the diode for half wave rectification. This is an inexpensive (yet vastly inefficient, which doesn't matter in this case, since the primary function is to generate heat) method of converting mains to a low DC voltage to power the circuit without the need for a bulky transformer or complicated SMPS.

[@mohanvvip]

Interesting! Thanks

[@phils4634]

Looks like one of the electrolytics provides a "smoothing" function, which would be more than adequate seeing the low power demand of the control system. You've got to wonder why they didn't go for an equally compact (and comparatively similar cost) modular full bridge (hat tip to Electroboom!), and design the pcb accordingly. Probably shaving a few cents on the design (which for a bulk manufactured item will translate to hundreds or thousands of dollars extra profit).

I love my sun beam toasters. I have rebuilt a bunch of them. The way they get the toast to lower is ingenious they have leaf springs that when heated loose there spring and the weight of the bread will take it down. Then when it's done it cools off and back up it goes. What other mechanical device could work on a daily basis for a hundred years and still make perfect toast. However my favorite toaster is the toast-o-laser the toast walks through a heating element. And it has a window for your enjoyment!

[@kevin67k]

Actually, after looking at the goofs & outtakes at the end of the video, I think he was trying to get through a long set of talking, with the toast in the toaster in the down & on position, before it popped up. But, because the toaster was so warm after each “take,” it would be too warm and would shorten the timing cycle, because of that advanced technology in the toaster’s timing circuit, causing it to “pre-maturely” “ejectulate” his toast. In other words, he was trying to lengthen the cycle to “keep it from popping up,” rather than trying to shorten the cycle or pick an “earlier time to pop up the toast,” before the toaster was actually ready to pop up.

So I bought a newer, fancier one on Amazon (a Cuisinart !) only to realize that I had neglected to notice the "cancel" button on both my other toasters. Now I am stuck with the 2 newer toasters plus my old Cuisinart. So this video helped me greatly, since I plan to dissect my old Cuisinart and see if I can 'fix it.' ...that is clean up the worn/ sticky spring and contacts mechanism and see if that does it.

I worked in the electrical trade for most of my life. It was interesting watching the development of toasters over the years. The first automatic toasters had bimetallic strip that handled the timing but if you toasted toast slice after slice they were not very accurate simply because the strip became hot and was not reliable. Then toasters came out with a 555 timers and electromagnets. Personally I just use a Dualit toaster that does little apart from heat bread to make toast. The timer is mechanical and the toast does not pop up. It's brilliant how technology goes backward and the timer is mechanical.

You prune all modern toasters pop up automatically but yours must be really outdated if it never pops the bread bsck up automatically

Nope. Dualit still make toasters that don't pop up. Have a look at the Dualit classic toaster, they have been making pretty much the same toaster in the UK since the 40's. You press a lever down, it pushes the ejector fingers up and you can get your toast. It's quite handy as you can push the lever down to pop the bread up to see how toasted you bread while the toaster it still on. Take the toast if you happy with it, or pull the lever up to carry on toasting.

The motor in our car, a Nissan sentra 1981, was using a bimetallic handle to close the choke --- automatically, not human intervention. The physical motion of the bending rod was used directly. It was not an electrical switch which would activate a motor or electromagnet. This allowed to keep the choke for a longer time period when the motor was really cold. The gas pedal was disengaging the choke even when the bimetal thing still didn't feel warm enough to do its job. When you were starting the car in winter, going back inside the house to warm up, you could hear after a few minutes the motor idling at a mad speed, probably 2500 RPM. We had to rush in the car at tap to throttle to finally hear the motor slowing to a more safe RPM of 900. This interlock was another ingenious improvement over older motors.

[@tomschmidt381]

Always enjoy learning about clever ways to solve problems. When you mentioned magnets my first thought was Curie effect, as in my soldering station. But toast does not get that hot, even burning it.

[@stephensnell5707]

It actually does get quite hot and you csn feel the hest of it if you take it out straight after it pops up

[@johnnz4375]

Just a small correction , the diode is there as a half wave rectifier for the power supply they take the power of 1 of the 4 heating elements and as they are in series you end up with mains voltage/4 so in the U.S. about 25vac after rectification there is around 12 to 15 dc left what is used for the electromagnet. There is no control for the elements except on and off. For the rest a good video.

I feel like this a video James May (from Top Gear) would make. I love how he and Alec make the mundane so interesting.

I've always wondered how that switching method worked, btw I've still got my grandads Morphy Richards toaster from the 1950's. Works perfectly, built to last!

It’s been a while, but I was in a vintage toaster, the ones I remember had an electromagnet as the release. The temperature setting adjusted contacts on a bimetallic thing, when it flexed far enough to make contact it would send power to the coil, and then pop the release. But I want to say some also used the bimetallic strip to break contact on a magnet like this too. I’ve only been in older toasters with the all mechanical temperature control, never a circuit board model.

I grew up with one of those Sunbeam toasters. My Das was actually a repairman for Sunbeam. We had all the best appliances. The electric skillet my parents got for a wedding present in 1963 is still cooking and better than any one I could find now new.

[@AnalogThinker]

For taking mine apart for repair, I realized the yellow lead you have should be connected at roughly 10% from the end or begining of your heating element, thus providing 10% of the voltage for the low voltage side of the circuit to operate (voltage divider). Another genius way to get things done without a transformer or switching power supply!!

[@vaylonkenadell]

Fun fact about the word "toast": the 1984 film _Ghostbusters_ contains the first recorded instance of a slang usage of the word meaning "something that will be no more; something subject to impending destruction, harm or injury". "This chick is *toast!"*

[@MOSMASTERING]

Too awesome.. To complete this video however, you need to mention Talkie Toaster.

[@ScorpioHighlander]

Wow... how much bread did you waste in the making of this video? I mean if you don't like toast and with all those out takes I can't imagine you ate it all. Also, this is the second time you've reminded me of Red Dwarf.

[@StephClo]

I would guess that he reused the same toasts, as it would probably take to long to wait for each set of toasts to grill just to make this video. Since he knows well how it works, it is (somewhat from what we saw haha) easy to control when it pops 🙂 anyway, only he can confirm how he did it 😉 PS: sorry if I made mistakes, english is not my first language

[@samhickman3813]

Unfortunately you overlooked the most important unanswered question facing the toasting world. Can you pause toast?

[@CaveyMoth]

And can you buy pre toasted toast?

[@Patrick_AUBRY]

@@CaveyMoth pre heated, pre bord, pre-recorded and now pre toasted? ;-)

Would save you from cold toast when the eggs get burned and need to be redone. Make it a smart toaster too, then you can just say, "well shit, Alexa pause toast!"

2:25 "Through the magic of buying two of them." Reminds me of craft shows, cooking shows and the like that used the magic of T.V. or pre-preping stuff to make the show go along smoothly.

[@ao4v0ws]

It's funny that he explained all those details on how cutting the power to the electromagnet would end the cycle, but what he missed was an easy way to time the toast to pop on cue by just turning off the power strip that the toaster was plugged in to. By the looks of the extro, I got the impression that timing was something that took some time to get right. Although he might have taken the difficult road, it did appear like he took the fun road. LOL... awesome video!

[@BokBarber]

I have a prewar Toastmaster 1B9 toaster, the granddaddy of modern popup toasters, which has a fascinating mechanical timing mechanism. On its face, just winding a spring to toast toast doesn't sound too interesting, but it's actually more complicated than that; for one, the mainspring in the movement is a bimetal. This means that at lower temperatures, the spring winds less tightly than at higher temperatures, so a hot toaster shuts off more quickly than a cold toaster. Adjusting for lightness and darkness also adjusts the winding on the spring. Second, instead of an electromagnet, the unit uses an entirely mechanical device to switch on and off. A regular magnet is attached to a flexible piece of metal. Pushing the lever down makes the magnet snap into place over two contacts to complete the circuit, while simultaneously winding the watch mechanism, pushing down the floor in the toaster to lower the bread, and locking the floor down. Once the magnet snaps in, the the toaster turns on. (It takes quite a bit of force to push down the lever on this model.) The lever slowly rises as the clock ticks away, and after a certain point, it will rise enough to pull the magnet away from the contacts. When it does this, the contact will be lost and the toasting is done. When the magnet lets go, it causes the lever to fully travel back up, which hits a switch to unlock the bread floor, causing the toast to pop up. The fact that engineers poured so much time into making such a complicated mechanism, just to toast bread, is fascinating to me. This is a device with some of the most interesting mechanicals I've ever seen, hooked up to a literal swiss watch movement, and it's sole function is to burn bread in a controlled way. It's also interesting to see how in later years they were able to accomplish the exact same thing with a significantly simpler mechanism (though I maintain that this toaster has done the best job at perfectly toasting bread of any toaster I've ever owned.) The unit was something like $450 adjusted for inflation, and a new toaster can be had for less than $10.

[@jackhewitt7902]

7:22 the circuits dead! 😭

[@apteropith]

That old toaster looks like it plugs into a _light bulb_ socket. Would certainly work, I guess.

[@strehlow]

It did. They were used for light bulbs, fuses, and outlets. Not terribly safe, I might add. Our "modern" sockets came much later.

[@musaran2]

This was common yes. Light bulbs were the first widespread electric appliances, so their sockets were the de-facto plug standard. A bit like cigar lighter is for car appliances now. There were things like "strips" you could plug extensions AND a bulb in, yikes !

[@Lauren_C]

I would like to see a history of Credit Cards. The remarks that will be made...

[@phils4634]

Especially the introduction and evolution of the chip on board technology

[@illfayted]

After watching this and getting a good look at the electromagnets and how they worked, I was able to figure out that the reason my toaster wouldn't stay down was because there was some burned on toast crud keeping them from making contact properly, so with a bamboo skewer and the flashlight from my phone I was able to scrape it off through the lever slot and fixed it without even having to disassemble it. Thanks!

[@rexijay]

I was actually looking for the function of the parts of a pop-up bread toaster. This video nalied it. Thanks!

[@peppeddu]

3:00 "High tech insulated poking devices" AKA a pen.

[@Membrane556]

The four pin chip is probably a timer chip similar to a 555 vs a microcontroller.

[@phils4634]

Might not be. The market for electronic toaster control Worldwide if sufficiently vast to allow the cost effective development of specific single-application ICs. Mind you it is now possible to buy single-shot programmable microcontrollers for as low as 3 cents each (when buying by the 1000 units).

[@freegeekdude1503]

One day google will make a toaster and call it the “Chromium Toaster”

[@BennoWitter]

I don't have a fancy magnet toaster. Mine is from the 60s and I bought it almost 30 years ago on a flea market for the price of what was around 25 US cents back then. I use it every days and it does what it is supposed to do.

[@for7hyp3]

That yellow wire connected to the diode was most likely the power input to the IC circuitry, they were using the nichrome wire as a voltage divider and the yellow wire probably just tapped into the heating element close to the neutral side so that it was taking like 12V or something off the element and using the diode and capacitors to convert to DC and smooth it out.

[@bjiirn]

10:24 now knowing how a toaster works you could have controlled the toaster with a foot switch...

[@alexanderpasnl]
