Hi Vince im glad you ok, great video its a shame how they made the blender like they did and what stopped it from working was a fuse on the board seem like everything they make these day once it go's wrong just put it in the trash thanks for having a go.
Thanks for sending them in Steve. I've had a few comments on the HDMI switch so I might make a quick revisit video on these things. I'll pin this comment Steve so viewers know it was you that sent them in 👍👍👍👍👍👍 If you don't want to be pinned just let me know and I will unpin it. Thanks again.
Wonder why waste fuses if there isn't a way to access it. Why don't companies use a reset able variable in place of fuse or fuse panel. Maybe if they were regulation in place for these issues. I understand the fuse is a safety mechanism but a fuse is to protect the item as much as prevent a fire.
@@christopherdecorte1599 Simply greed, that way you need to buy a new one every time it breaks. It pisses me off the way things are done now, you see machines from the 60's working perfectly still, and that is not just blind luck. They really were built so much better in the past.
@@christopherdecorte1599 Yeah, sometimes they use only the fuse, sometimes they use fuse and a varistor to make a circuit ''breaker''... You may not believe it, but sometimes they don't use any fuse or other security from a short or the overload in the device although the device operates on a high voltage... Cheers!
Given that Steve sent you two items that had blown up or blown a fuse, you have to wonder if he has a problem with his mains power at home. Thanks for the video.
I'm guessing the discrepancy between the USB cables is because the first one you showed was of crappy quality, they're often made with aluminum wires (instead of copper) that i guess in this case had enough resistance for the usb power bank to not detect it as a short. The second usb lead you used looked to be of better quality, so its resistance was negligible and the power bank correctly shut down to protect itself when it detected a short at the other end
Yes this is correct. The pathetic few strands of aluminium will also be twisted with some fabric to pad it into a thicker gauge too. There was also a 0.1V difference between the leads. Vince should measure the resistance across the leads and see what's happening.
Hey Vince. I appreciate your respect for high voltage electricity. Its too often I see people having no regard for it, and endangering themselves. You have a genuine fear, that will keep you alive for a very long time. thanks for showing people how dangerous this could possibly be.
You know Vince ever since electronics jumped from the valve to the transistor then ic its always been a mystery to me. It's only thanks to your videos its become much clearer. As to the boom from the blender, I have to say I do that more often than not the latest being connecting the 240 volts to the low voltage end of an LED light transformer. The last time before that I blew up the solar panel inverter. Life, where would we be without it, it's a constant learning experience. Thank you for this video and all the others Vince its always a pleasure watching you repair stuff a real pleasure.
Fixed our Braun mixer of same design a while back, not only does it come apart super easy, they publish the exploded diagram and you can order spare parts directly. For ours it was 5€ ordered directly from Braun and arrived the next day.
My great grandmother, rest her soul, bought a sunbeam blender in 1970s and to this day it still works perfectly fine. They just don't make stuff like they used to. The fact that the primary use of an electric fuse is to protect electrical equipment from getting fried is a little suspicious in a product that is not repairable. But I am not a licensed electrician so I'm not 100% sure. Regardless it was a great video to watch. I smiled and laughed so much when you brought out the guitar hero controller. Keep up the good work. 👍🏻
I have a drill from the 40's and it will literally break your arms if you are not careful. I also have a modern drill that just quits when drilling anything harder than balsa wood.
What an explosive edition Vince and glad you got nothing more than a fright.made for excellent viewing and you should be up for an award for that😂great bit of good honest bodging.
For a second there I thought I was watching an Electroboom video! Keep safe Vince and don't let things blow up in your face. You might consider a face shield, we don't want anything to happen to your rugged good looks.
That guitar hero guitar is now the main instrument of safety precautions! We are going to need it doing some more cameos on upcoming videos Vince! That was so funny you had me roling here! hahahaha
New undies for Vince please! and some new eyebrows! Good video as always! nice to see you attempt it and i am so glad you used a insulated driver rather than haphazardly pressing the button this time.
Hi Vince, I have tried to fix a blender that looks almost identical. There are two things about this blender. First, I also found it extremely difficult to dissemble it, but eventually I've found that there is a hidden screw behind the button panel that hold the upper and lower chassis together. If you peal off the button panel, you will see the screw. Second, I also found a blown fuse on mine. I replaced the fuse and tested it running great. I happily returned it to my wife but found out that the fuse blow again if the blender is used on any thick or sticky paste. When I tried to fix it the second time, I found that the brush as well as the motor commutator is so wear off, and that's why the motor lost strength and the fuse blow so easily. I tried to find the same motor to replace it but it is almost impossible.
The difference between the cables are that they are different quality, Cheaper ones have thinner wire and act more like a resistor in high loads limiting the current. And some motors have a back EMF diode between the poles to protect circuits from voltage going back into the board and then this diode short the load if you reverse polarity, that or the motor was already shorted for some reason
i guess that the motor is going to spin the wires and PCB through the air like a 240v windmill of death .... [EDIT: i was wrong but holy shiii i am glad that blew before it turned on, that was exceptionally dangerous ] had me laughing my ass off though, oh Vince you're a national treasure ...thought about getting a job with Medhi @ElectroBOOM? he'd have been proud of that one LMFAO, glad you are okay
The USB lead will have a resistor across the data pins which tells the power bank the devices power requirements. My guess is something about the different resistor values and the fact the device is faulty is causing the power bank to behave differently.
Interesting with the motor. Just a little bit of advice. You put the extension on the table you put the blender in to the extension and then you plug it into the wall. you still left loads of the extension on the real. This acts like an heating element and can set on fire. Just letting you know.
It's good to see the fkups Vince cos then we know what NOT to do. If a repair goes smoothly, it's great, but the BANGS are definitely more educating and entertaining.
Every cable/lead/wire/trace has a certain amount of resistance and acts as a resistor. The resistance is a function of wire diameter vs wire length. The thicker the wire, the lesser the resistance, while the longer the distance the higher the resistance. The USB lead that was getting hot was acting like a resistor and dropping the voltage.
Connecting the polarity incorrectly didn't cause the death of the motor. That is a permanent magnet DC motor and will just change the rotational direction by swopping polarity. What did happen though was the result of a short circuit in the rotor windings.
Hey vince, in my experience I have never seen a dc motor that can only go one way. (That doesn’t mean that there isn’t) but the board worked. Who’s to say that the motor wasn’t actually faulty (it could have kicked that brush, and got stuck causing a short) and blown the fuse. You powered it backwards freed the brush spitting it out. Maybe the brushes were worn out. It did look tiny. There really should not been a way under normal operation that you could cause that to happen.
The DC motor should have worked worked backwards but I expect the motor had already failed before you received it and had gone short circuit due to overheating / overloaded (windings shorted due to overheating, maybe a very thick soup or used for too long). PS. I'm loving the Guitar Hero finger extension, can you please sell them on Ebay, I want one.
Frying tonight, Vince and chips. Yep take more care fella, such as investing in some safety specs. I agree with the cheapness of things and un-fixable stuff. No wonder Maplin went bust (Tandy's for the USA folk). You can make something waterproof with correct seals and sound screws. You don't have to glue things up like that, and 6 quid for a HDMI well good luck to a seller, you will need to sell 1M of them to make 10 bucks. Daft. Anyway great video, yep check polarity always.
Answering your question - the first thing I thought when I saw you soldering the motor wires was - he didn't check the polarity - and seeing the wires were red and black, that could probably cause problem. But that's absolutely OK. On the other hand, manufactures producing items that cannot be repaired is a clear sign of how stupid we are as a species, considering we only have one single planet to live on. Remember Wall-E? Those guys had a spaceship to go to when things got impossible here, but what about us?
Happy Thanksgiving to you and your family Hope you have a wonderful holiday You I appreciate you taking the time Outshow Video Thank you so much I give you 2 million thumbs up
I have bought a couple of these to use on projector DVD player and tv . And I can’t get any of them to work .so not sure if I’ve fitted something wrong 🇬🇧👍
Get yourself a variac (variable transformer) with a safeblock isolation connector...set to 0v and increase gradually...the transformer starts to growl when under load so you know not to increase the voltage any further....safer and less damage than direct connection to 240v....though they are expensive....though how much is human life....?
The USB has a higher resistance than the other one, It`s made of thinner wires or crappy wires, DC motor or ac motors do not care about polarity, I think one of the diodes are leaky
I don't think the cause of the explosion was the wrong wiring, simply the motor would have rotated but in the opposite direction to that designed, but nothing would have happened, but if the motor winding was shorted, that's another story
ok, i know this is older-- but from what i have seen.. as a brother across the pond... maybe stick with devices that run on batteries for the time being :D ty for the videos-- just use care,, 350v into a thumb can hurt ;)
It make no sense with some sales i bought a ps1 game other day for £2.99 the postage label said over £2 i wanna say £2.15. werent really worth selling.mseller then realised theyd sent me wrong one and was going send correct but i only wanted ut to test a console id bought to mod chip. So would of been another cost. Turns out discs i was burning with ended up being the culprit for not working. i was thinking id buggered up the chip my first attempt at something like that. Always fixed things but never added to or modded something.
Really don't think the motor gave a damn it was reversed it was probably screwed beforehand the housing was probably full of soot if you looked up inside it.....
It's not great that it is internally fused in such a way that makes it un-repairable, seems a bit pointless in the UK at least as our plugs are all fused anyway.
OMG dude are you really gonna turn that motor on with 240v wires hanging off of it!? LOL. Yes, yes you did. LOL Dude you need to be more careful ha. Id say there were a few mistakes made haha, not just one. The screw driver taped to a guitar hero guitar made me laugh my a$s off hahah
I would suspect too much draw was on that blown chip, maybe someone had less than a perfect cable going in on a couple and just pulled the guts out of it esp as some HDMI is a power transfer as well... too many angry pixies and boom bye bye chip.
LMFAO @ the guitar hero "distance" power on!! Before you blew it - my first concern was a motor just sat on a desk like that! Often the torque of it starting to turn can rotate the chassis in place, meaning the wires would follow with it, flipping the PCB up in the air off the table - that could have ended badly, I am glad it blew for that reason! Great video again Vince =D
I was thinking the same about the motor torque thing too, as I did the exact same thing when repairing a Milwaukee vacuum cleaner a week or two ago and it flew out of my hand!
😂😂 Yes, that would have been more dangerous if it landed on my lap repeatedly shocking me with each twitch from my electrified body. Good point Chris, it has been noted for future fixes. Thanks mate 👍👍👍👍👍👍
Hey Vince, I've been fixing stuff for well over 40 years and I can tell you that blowing things up is all part of the experience. I used to do repairs professionally but these days I just do it as a hobby but even today I can still have the occasional bang and puff of smoke. Most of the time it's not very dangerous, but a pair of safety goggles is a very handy addition to the toolkit - I had a close call back in the early 2000s when I accidentally probed the live side of a switching power supply with a grounded oscilloscope probe, and got hit in the face by a piece of the bridge rectifier which exploded with one hell of a bang. Since then I've always chosen to wear goggles when working on anything with a significant amount of power going through it. Glad you didn't hurt yourself with this one. Most of the time, these type of incidents are no more than a good jump-scare, but my own experience tells me that eye protection should be regarded as essential for this sort of thing. Note that a dim-bulb tester is a handy tool for working on mains stuff - there are plenty of videos on youtube that show how to make one very easily and cheaply, and it's invaluable for saving fuses and other components by acting as a fairly heavy-duty current limiter, and of course a handy indicator of a dead short, lighting up brightly thus dissipating the energy that would otherwise blow something up...
Hey Vince, I have another theory for the blender. I think the motor was already defective which made the fuse blow originally. It's just a DC motor and polarity shouldn't really matter. But they put a positive sign at one end so that it will only spin in correct direction, and workers assembling it don't have to guess.
About the motor is that sometimes they have a back EMF feedback diode across the poles to protect against reverse voltage going back to the circuit board and if you reverse such motor the diode will short the load. it is likely this was the case or that the motor itself was already shorted
Great video, Vince! My old german mixer is not glued together, it can be fixed any time. And it also has an AC motor, too. That is why I am never going to replace my 45 years old kitchen equipment. However, if you spin a DC motor at the same direction all of its lifetime, the brushes will wear enough that the motor will get stuck if you try to spin it the other way. That is when it spits out those brushes. In an RC car, you most likely flip the direction from forward to reverse every time you want to change the direction of the car, so that is why it can work in both directions.
Hi Vince, two things. First, the USB lead was probably cutting out due to being better quality, where as the other lead was acting like a heater wire (due to thin cable or aluminium wires) and just heating up and acting like a resistor. The second I think that motor on the blender was shorted before you plugged it in (and that's what took out the fuse initially). I think it would have just span the other way if wired in reverse polarity, so I wouldn't be to hard on yourself with that one!
Thank you Mick, I didn't think of that regards the motor. If the motor was faulty before I got my greasy mitts on it, why did it not blow in that spectacular fashion originally when the manutacturers fuse blew. Could it be that my 2 Amp fuse is better and allowed 2 amps before blowing whilst the one on the board might have blew at 1 Amp although marked up as 2 Amps on the board? Cheers Mick
@@Mymatevince Not sure on that one Vince. Definitely looked like an internal short.. looks like the motor may have been jammed or too much strain put on it perhaps, which may have caused the insulation on the windings to break down and it blew properly on the 2nd go.. I know one thing.. the 'jesus christ' made me LOL!
@@BuyitFixit Made me do a little more than laugh😬 those sparks really flew at me. Cheers for getting back to me. The faulty motor idea makes more sense than the fuse just blowing 👌
I’ve seen a few PCs with faulty PSUs that cause the plug fuse to blow first. Then after that is replaced the next time you plug in the PSU explodes instead of the new fuse.
Boy, when I saw the guitar hero being deployed I thought 'crikey, Vince is tightening his G string for this one' 😃😃 Great video Vince as always. Now about the running through the house with scissors video....
I learned something from this video, DC motors may have polarity controllers that pop when polarity is reversed, stick blenders may have DC motors in them, and that Vince is the most entertaining of the channels I follow.
Hi Vince, I really like your videos. But I noticed that you said the Lord's name disrespectfully in the video. So I was wondering if you could please not do that anymore. It is a big deal. And believing in Jesus and accepting him as your Lord and savior is the only way that you can go to heaven when you die. And the Bible really is the truth, it even says what is going to happen in the future in the book of revelation. I thought it was crazy when I saw the part that said in the future it will cost a day's wages just to buy a loaf of bread. And there is even going to be a time when Satin trys to force people to get an evil mark on their right hand or forehead. And it will have something to do with the number 666. And people will be doomed if they get it. And it will be to late for them if they get it. At first people won't be able to buy or sell anything if they don't get it. But later people will be executed if they don't get it. So I also wanted to mention that people that have never read the Bible have misconceptions about it. But if you actually read the Bible and not just a random verse you will see things differently. If you don't have a Bible I would recommend searching for the NIV version. Most people don't realize how big of a deal this really is. But accepting Jesus as your Lord and savior is literally the most important decision you could ever make in your entire life. And that decision will affect you for ever. So I just wanted to mention that I'm not trying to make you feel bad. I'm only telling you this because I care about you. There are a lot of people that act like its controversial to talk about the Bible and a lot of people are uncomfortable for some reason. But maybe its because society is different these days. Well it was nice talking to you Vince. I hope you and your family have a nice Thanksgiving. There is actually one more thing I would like to mention. There are some people that also choose to not think about eternity and they just forget about it. So if they do that, then they are also making their decision. When it comes to someone accepting Jesus as their Lord and savior and going to heaven when they die. The choice is only Yes or No. And there is no other option. So when it comes to the Bible the people that just forget about it and don't think about eternity. They are also still making their decision. Thank you Vince, for reading my comment. I'm sorry that its so long. But it is really important. And it was on my heart to explain it to you.
In most cases electric DC brush motors can run in both directions. Some manufacturers adjust the angle of the brushes to minimize the spark generated when the carbon and graphite brushes make contact with the commutator, thus polarity is important as attempting to run in reverse the brushes act like a break and prevent the shaft from spinning. You can clearly see a rather big spark when you first tested it when the shaft was attempted to run in reverse but couldn't as the friction from the brushes prevented it, good work Vince, please be careful with high voltage appliances, maybe sellotape two guitar hero guitars together next time!
Interesting to see a DC motor used at mains voltage, so at least we know it will have a FULL BRIDGE RECTIFIER! :D In fact my guess is that this is pretty much all that's in it - full bridge and maybe a capacitor (there did appear to be a big X2 on the board, and the turbo switch probably bypasses another diode on the AC side to limit it to half-cycles. Without seeing a schematic it's hard to know but I didn't see much else on that board other than a few diodes, the cap and a couple of microswitches. It did all look pretty well made though. Pity about the non-repairable case :(
the cable section may be the difference between the two. the thicker cable can carry more current which the power supply interprets as abnormal consumption and shuts down. the cable with a smaller section carries less current which is not sufficient to trigger the protection mechanism.
Hi, I have 2 more Rolls Royce episodes edited and waiting to be released, part 29 and 30 and part 31 needs to be edited. In fact the reason for the delay in videos this week is because I been working on part 31 for 3 full days! Hopefully part 29 will be out soon👍
@@Mymatevince Part 29 should have been out today and this video could have been an inbetweener/teabreakfix. We're spoiled of the good stuff you put out now!

Was just going to post similar, I guess the cable that doesn't cut, out the wires have a higher resistance and are just heating up.
Yes this is correct. The pathetic few strands of aluminium will also be twisted with some fabric to pad it into a thicker gauge too.
There was also a 0.1V difference between the leads. Vince should measure the resistance across the leads and see what's happening.
...which as Buy it Fix it says would explain the heating as well, with 7.5 watts dissipated in it!
Other guess would be that the barrel plug polarity is different, but then they wouldn't have both worked on the other unit.

Vince, the Steve Irwin of electronic repairs
One lead has thinner conductors so can't pass enough current to trip the short circuit protection. It just heats up instead.
The guitar hero push was hilarious..........
The USB lead will have a resistor across the data pins which tells the power bank the devices power requirements. My guess is something about the different resistor values and the fact the device is faulty is causing the power bank to behave differently.
Safety goggles, Vince.
As always, very entertaining Vince. I will do my best to not copy you 😜
It happens to the best of us, no worries

So much excitement to see you in Notification Popped Up First video you uploaded since i subscribed your channel 😉
guessing the resistance on one lead was higher than the other and thus not allowing the circuit to reach the "cut out" threshold.

Some hdmi switch cables have a huge resistance!!!!!!! thats why some cables will get warm!
I have bought a couple of these to use on projector DVD player and tv . And I can’t get any of them to work .so not sure if I’ve fitted something wrong 🇬🇧👍
The HDMI Switch that you tried to Fix are bad anyway, I bought the same one and after a few Days it started to introduce Digital Noise.
I am a bit concerned about the voltage supply to your house. 288v ???
Lesson learned. But so annoying that the whole thing ends up as landfill, just because of a 2 amp fuse. As you say ‘race to the bottom’.
Get yourself a variac (variable transformer) with a safeblock isolation connector...set to 0v and increase gradually...the transformer starts to growl when under load so you know not to increase the voltage any further....safer and less damage than direct connection to 240v....though they are expensive....though how much is human life....?
The USB has a higher resistance than the other one, It`s made of thinner wires or crappy wires, DC motor or ac motors do not care about polarity, I think one of the diodes are leaky
Thanks AR. Regarding the possible leaky diode...would that be one of the 4 diodes converting AC to DC or one of the components in the actual motor?
@@Mymatevince Yes or the motor is burned out
@@AnonymousRepair Cheers AR👌
If it wasn't broken before, it is now.
stopped at 14.59 and motor counter rotation will cause a cluster flux
A new tool added to the arsenal, a Gibson guitar hero guitar....
old devices have an bottom that screws on the top bit wit a rubber seal that's the safe solution instead of glue.
NOW, is it that you still didn't press hard enough?!
iso alcohol is good for melting hot glue
20:00 ah yes, a broom for pressing a switch from a safe distance... that's the most obvious way.
Not all cables are created equal.
They may have the same plug but the data speeds and power transfer capabilities vary wildly.
Might wanna spend some money on safety goggles and an electrical reference manual. Sheesh.
Trying to give Mehdi a run for his money i see haha
I don't think the cause of the explosion was the wrong wiring, simply the motor would have rotated but in the opposite direction to that designed, but nothing would have happened, but if the motor winding was shorted, that's another story
ok, i know this is older-- but from what i have seen.. as a brother across the pond... maybe stick with devices that run on batteries for the time being :D ty for the videos-- just use care,, 350v into a thumb can hurt ;)
You trying to give ElectroBoom a run for his money? :p
Trying to be electroBOOM now eh? Haha
Hi Vince
Rolls?
Why put a fuse if you put it in an area you can't access.
Can't win them all. I've killed more than one thing with reversed polarity :(
It make no sense with some sales i bought a ps1 game other day for £2.99 the postage label said over £2 i wanna say £2.15. werent really worth selling.mseller then realised theyd sent me wrong one and was going send correct but i only wanted ut to test a console id bought to mod chip. So would of been another cost. Turns out discs i was burning with ended up being the culprit for not working. i was thinking id buggered up the chip my first attempt at something like that. Always fixed things but never added to or modded something.
i think you should take apart your HDMI switch to compare, I bet they are both the same.
Really don't think the motor gave a damn it was reversed it was probably screwed beforehand the housing was probably full of soot if you looked up inside it.....
It's not great that it is internally fused in such a way that makes it un-repairable, seems a bit pointless in the UK at least as our plugs are all fused anyway.
It might not be glued. A machine clamps and Sonic welds it together making it one piece and impossible to take apart. Take just a second.
hi there is money in them they buy about 100 at one go from far east there would be a 1 pound made on each
so ebayer would make money over time
OMG dude are you really gonna turn that motor on with 240v wires hanging off of it!? LOL. Yes, yes you did. LOL Dude you need to be more careful ha. Id say there were a few mistakes made haha, not just one. The screw driver taped to a guitar hero guitar made me laugh my a$s off hahah
Should make a merch shirt of a guitar hero guitar with a screw driver taped to it. LOL.
My Mate Vince needs new pants after that 🤣
I would suspect too much draw was on that blown chip, maybe someone had less than a perfect cable going in on a couple and just pulled the guts out of it esp as some HDMI is a power transfer as well... too many angry pixies and boom bye bye chip.
vince mate can u order me a new pair of kelvins i just fudged mine wen that bang went off holy crap lol
Fk sake Vince you certainly keep us on our toes
😂👌
LMFAO @ the guitar hero "distance" power on!! Before you blew it - my first concern was a motor just sat on a desk like that! Often the torque of it starting to turn can rotate the chassis in place, meaning the wires would follow with it, flipping the PCB up in the air off the table - that could have ended badly, I am glad it blew for that reason! Great video again Vince =D
I was thinking the same about the motor torque thing too, as I did the exact same thing when repairing a Milwaukee vacuum cleaner a week or two ago and it flew out of my hand!
Classic MMV. It’s too cold to go get the broom so he tapes a screwdriver to the end of a guitar hero guitar. My hero.😊
😂😂 Yes, that would have been more dangerous if it landed on my lap repeatedly shocking me with each twitch from my electrified body. Good point Chris, it has been noted for future fixes. Thanks mate 👍👍👍👍👍👍
Definitely stealing that Guitar Hero/Screwdriver combo tool 🤣
No Thanksgiving Day is complete without Vince blowing something up. Thank you for the enjoyment today. Love your videos no matter if a win or a fail.
Maybe they soldered the wires on wrong at the factory?
Hey Vince, I've been fixing stuff for well over 40 years and I can tell you that blowing things up is all part of the experience. I used to do repairs professionally but these days I just do it as a hobby but even today I can still have the occasional bang and puff of smoke. Most of the time it's not very dangerous, but a pair of safety goggles is a very handy addition to the toolkit - I had a close call back in the early 2000s when I accidentally probed the live side of a switching power supply with a grounded oscilloscope probe, and got hit in the face by a piece of the bridge rectifier which exploded with one hell of a bang. Since then I've always chosen to wear goggles when working on anything with a significant amount of power going through it.
Glad you didn't hurt yourself with this one. Most of the time, these type of incidents are no more than a good jump-scare, but my own experience tells me that eye protection should be regarded as essential for this sort of thing.
Note that a dim-bulb tester is a handy tool for working on mains stuff - there are plenty of videos on youtube that show how to make one very easily and cheaply, and it's invaluable for saving fuses and other components by acting as a fairly heavy-duty current limiter, and of course a handy indicator of a dead short, lighting up brightly thus dissipating the energy that would otherwise blow something up...
Hey Vince, I have another theory for the blender.
I think the motor was already defective which made the fuse blow originally. It's just a DC motor and polarity shouldn't really matter. But they put a positive sign at one end so that it will only spin in correct direction, and workers assembling it don't have to guess.
About the motor is that sometimes they have a back EMF feedback diode across the poles to protect against reverse voltage going back to the circuit board and if you reverse such motor the diode will short the load. it is likely this was the case or that the motor itself was already shorted
@@Pulverrostmannen I like that explanation.
@@NicksStuff Thank you :)
Great video, Vince!
My old german mixer is not glued together, it can be fixed any time. And it also has an AC motor, too. That is why I am never going to replace my 45 years old kitchen equipment.
However, if you spin a DC motor at the same direction all of its lifetime, the brushes will wear enough that the motor will get stuck if you try to spin it the other way. That is when it spits out those brushes. In an RC car, you most likely flip the direction from forward to reverse every time you want to change the direction of the car, so that is why it can work in both directions.
Ahh, thanks with the brush explaination
Hi Vince, two things. First, the USB lead was probably cutting out due to being better quality, where as the other lead was acting like a heater wire (due to thin cable or aluminium wires) and just heating up and acting like a resistor. The second I think that motor on the blender was shorted before you plugged it in (and that's what took out the fuse initially). I think it would have just span the other way if wired in reverse polarity, so I wouldn't be to hard on yourself with that one!
Thank you Mick, I didn't think of that regards the motor. If the motor was faulty before I got my greasy mitts on it, why did it not blow in that spectacular fashion originally when the manutacturers fuse blew. Could it be that my 2 Amp fuse is better and allowed 2 amps before blowing whilst the one on the board might have blew at 1 Amp although marked up as 2 Amps on the board? Cheers Mick
@@Mymatevince Not sure on that one Vince. Definitely looked like an internal short.. looks like the motor may have been jammed or too much strain put on it perhaps, which may have caused the insulation on the windings to break down and it blew properly on the 2nd go.. I know one thing.. the 'jesus christ' made me LOL!
@@BuyitFixit Made me do a little more than laugh😬 those sparks really flew at me. Cheers for getting back to me. The faulty motor idea makes more sense than the fuse just blowing 👌
I’ve seen a few PCs with faulty PSUs that cause the plug fuse to blow first. Then after that is replaced the next time you plug in the PSU explodes instead of the new fuse.
@@coctailrob 👍
Boy, when I saw the guitar hero being deployed I thought 'crikey, Vince is tightening his G string for this one' 😃😃 Great video Vince as always. Now about the running through the house with scissors video....
Another amazing video ❤️ rock and roll
I learned something from this video, DC motors may have polarity controllers that pop when polarity is reversed, stick blenders may have DC motors in them, and that Vince is the most entertaining of the channels I follow.
hi i think mains voltage dc motors have the brushes offset so they run more efficiently and better in 1 direction (reduces sparking)
Hi Vince, I really like your videos. But I noticed that you said the Lord's name disrespectfully in the video. So I was wondering if you could please not do that anymore. It is a big deal. And believing in Jesus and accepting him as your Lord and savior is the only way that you can go to heaven when you die.
And the Bible really is the truth, it even says what is going to happen in the future in the book of revelation. I thought it was crazy when I saw the part that said in the future it will cost a day's wages just to buy a loaf of bread. And there is even going to be a time when Satin trys to force people to get an evil mark on their right hand or forehead. And it will have something to do with the number 666. And people will be doomed if they get it. And it will be to late for them if they get it.
At first people won't be able to buy or sell anything if they don't get it. But later people will be executed if they don't get it. So I also wanted to mention that people that have never read the Bible have misconceptions about it. But if you actually read the Bible and not just a random verse you will see things differently.
If you don't have a Bible I would recommend searching for the NIV version. Most people don't realize how big of a deal this really is. But accepting Jesus as your Lord and savior is literally the most important decision you could ever make in your entire life. And that decision will affect you for ever.
So I just wanted to mention that I'm not trying to make you feel bad. I'm only telling you this because I care about you. There are a lot of people that act like its controversial to talk about the Bible and a lot of people are uncomfortable for some reason. But maybe its because society is different these days. Well it was nice talking to you Vince. I hope you and your family have a nice Thanksgiving.
There is actually one more thing I would like to mention. There are some people that also choose to not think about eternity and they just forget about it. So if they do that, then they are also making their decision. When it comes to someone accepting Jesus as their Lord and savior and going to heaven when they die. The choice is only Yes or No. And there is no other option. So when it comes to the Bible the people that just forget about it and don't think about eternity. They are also still making their decision.
Thank you Vince, for reading my comment. I'm sorry that its so long. But it is really important. And it was on my heart to explain it to you.
Electricity is like a wife, beautiful if you respect it and deadly if you don't!
Enjoyable video, Vince!
I respected them both, but muh electric wife killed me!
In most cases electric DC brush motors can run in both directions. Some manufacturers adjust the angle of the brushes to minimize the spark generated when the carbon and graphite brushes make contact with the commutator, thus polarity is important as attempting to run in reverse the brushes act like a break and prevent the shaft from spinning. You can clearly see a rather big spark when you first tested it when the shaft was attempted to run in reverse but couldn't as the friction from the brushes prevented it, good work Vince, please be careful with high voltage appliances, maybe sellotape two guitar hero guitars together next time!
Didn't expect an Electroboom style video from Vince today 😂
Interesting to see a DC motor used at mains voltage, so at least we know it will have a FULL BRIDGE RECTIFIER! :D
In fact my guess is that this is pretty much all that's in it - full bridge and maybe a capacitor (there did appear to be a big X2 on the board, and the turbo switch probably bypasses another diode on the AC side to limit it to half-cycles. Without seeing a schematic it's hard to know but I didn't see much else on that board other than a few diodes, the cap and a couple of microswitches. It did all look pretty well made though. Pity about the non-repairable case :(
Vince is preparing for a collab with ElectroBoom coming to UA-cam very soon.
Stay safe and keep up the good work 👍😀
the cable section may be the difference between the two. the thicker cable can carry more current which the power supply interprets as abnormal consumption and shuts down. the cable with a smaller section carries less current which is not sufficient to trigger the protection mechanism.
1 week wait for this video is a shame, was really hoping for rolls royce episode :(
Hi, I have 2 more Rolls Royce episodes edited and waiting to be released, part 29 and 30 and part 31 needs to be edited. In fact the reason for the delay in videos this week is because I been working on part 31 for 3 full days! Hopefully part 29 will be out soon👍
@@Mymatevince Part 29 should have been out today and this video could have been an inbetweener/teabreakfix. We're spoiled of the good stuff you put out now!
@@stzokev Haha, cheers Steve. I'm badly organised! I'll get Part 29 out to the Patrons tomorrow and then live here on UA-cam on Sunday 👍👍👍👍
