I am glad to see how wheels looks inside. I have bought hoverboard that has plastic (!) plate instead aluminum or magnesium alloy. Motors overheats and screws get loose after every 500 meters. Returned it to the seller (bought locally), but did not get refund yet (paid over $200). They sent it to some repair shop to test my claims that it is really bad board. Now bought used hoverboard with 10" inflatable wheels - what a difference!!! Small rocks and cracks in the concrete does not bothers me anymore. And battery seems last forever - my legs hurt, but battery still holds. No name, no brand... unknown origin, just amazing stuff for $130 (used). And it has bluetooth, not real sound quality, but id does not matter. Thanks for this video, it is inspiring.
I’m just now teaching myself how to build electronics.. I’m going to use these motors to build very small wheelchairs for little people, like me. I’m very impressed by your trouble shooting skills. This video taught me some tactics
The reason why you measured short on the charger port, is because the whole power rail was shorted because of the two blown mosfet. Thankfully the bms in the battery switched itself off, so the whole thing didn't go up in flames. As you removed the battery, the bms no longer sensed a shorted therminal and turned itself back on as it supposed to.
I had a quick question about the LIFi video you did . does you unit still work ok ? . tried to power one on with a 5v adapter and it worked for 10 sec and just turns off. thanks in advance
If you have a red flashing light on one side and it wont move and Recalibrate doesn't fix it... Check all plugs and wires are getting good connection (Especially the 5 wire sockets). If they are and it still don't move then it probly has a blown output fet on the side thats red. They're easy to change.. MAKE SURE BATTERY IS UNPLUGGED!! Measure the Mosfets, 6 on a heatsink per side(GDS)... Usually only 1 or 2 short... DMM to Diode, Neg on Center pin (Drain), Gate approx +1.5v, Source approx .5v. YST7575C crosses to RU6888R 68v 88a TO220
I just got a hover board and it worked fine. It was a hands free smart board x2 from swagtron. I works great but it doesn't charge like the others have posted below. When I plug in the charger the red light on the charger turns to green right away and the board just doesn't charge. I know that the charger light should be red when charging. The charging port is plugged in to the mother board. Would the board be defected or would you guess it would be the charger?
Awesome video! 11:08 light sensor is triggered by weight you stand, whereas forward /backward/acce/speed is controlled by gyro-sensor on the same board
Not that this matters on a 6 year old video but the foot switches have nothing to do with what direction the hoverboard travels. They are to sense when both feet are firmly planted on the board. The gyroscopes [solid-state] then detect the change in orientation of the rider [lean forward, lean backward, etc] and propel the motors in the appropriate direction and speed.
Mine would not calibrate so I opened it up and come to find out it was a yellow wire that was pinched near the center of the board. I repaired it it works great
Hello. Help me please. I click on the power button, and the scooter does not turn on. There is a squeak and squeaks all the time while I hold the button. The wheel rotates on one side if I hold the power button and press the pedal buttons. The wheel starts to rotate smoothly and accelerates when turning (tilting) and if you change the direction of inclination the wheel first brakes and then begins to rotate in the other direction. I can assume that the battery is alive. Wheel windings are good means faulty in the motherboard. Please tell me where to look for a fault and a possible method of troubleshooting. Thank you in advance, Vyacheslav
what is the type of connector to use on the hoverboard cables please? I would like to repair a broken cable without having to buy a card to have the cable. Thanks a lot
So a MOSFET failure (maybe from overheating) is something to look for when troubleshooting circuits. That is sometimes there's no other underlying problem, just that the heatsink was insufficient for heat generated with normal use?
We just kinda got lucky in this case. Sometimes the FETs going will take out other stuff in the process, but since nothing after them or before was shorted or anything, it seems the problem was just inadequate heatsinking.
hello sir after a ride of 15 minutes when we restart our scooter it denies instead it continuously beeping and when we step on it beeps chnge and led blinks.when we look at the motherboard a tiny red led blink twice continuously.please help
I have changed 2 mosfet for my HVB they were shorted, but after that i get short circuit and the fuse is damaged and i am try to get the reason but with any hope, if u can help me
My hoverboard is making funny moves when you put your first feet doesnt matter if its left or right and it keeps on beepin and it wont respond to you but it moves vibrate anyhow pls help me out
Okay I have another board will not power on when I plug the charger cord in it turns green when I plug it in to the hoverboard it stays green what could that be

You are sharp on theory, and have excellent analytical skills! I have learned much and look forward to Part 2! KUDOS!

Wow, you're smart...I have tried & tried to understand electrical/electronics to no avail! Maybe I can have Chat GPT explain it to me. 🤔 😁
thank you so much for making this video! very helpful!
How those Keysight multimeters compare to Fluke?

Do you how can I get the par number of ic #2 it is beside of the port that connects the switch to turn it on
I found u to fix a Neato, I’m back to fix my kids old Hoover board 😝

Built to fail ,,,,hmmmmmm
What is the stain on the table
OMG! Cover that beeper with tape.
jeeeze ! you are brilliant!!!
Thanks my grandson wants his fixed.
Can you fix my children's hoverboard
No not light at all. 45 volt battery is pretty heavy
Hey, i have the same type hoverboard as you have. But mine isn't turning on at all. My battery and the motors are ok. So what could the problem be?
Fpv Drone Videos the
mother board is bad
Ebay $24.99 buy 2
Good job

@@ThatElectronicsFool I see. I'm slowly building up a list of things to look for when troubleshooting circuits, and now it's grown one more item =)

Merhaba üstad.Hoverbord binerken birden kapanıyor.Açma kapama düğmesi basıldığındada açılmıyor.Şarj aletine bağlayıp çıkarınca yada içini açıp bataryanın soketini çıkarıp takınca cihaz açılıyor.Yorumunuz için şimdiden teşekkürler.
Very good job boss
Can you help me my hover board still not wrking but two lights green still on and the two blue lights on how can I fix it.. 😔
I have changed 2 mosfet for my HVB they were shorted, but after that i get short circuit and the fuse is damaged and i am try to get the reason but with any hope, if u can help me
So they dropped the over and your instinct was not to measure voltage at plug with multimeter. Weird. The plug is rarely an issue. Yup that's a short
can you help my hoverboard isnt wokg
Great videos !! Love this channel subscribed
finely
ty.
Such lovely person
I had the same mosfets fail , 3rd from the left
660AT 65V 110A 6.1Ohms
My hoverboard is making funny moves when you put your first feet doesnt matter if its left or right and it keeps on beepin and it wont respond to you but it moves vibrate anyhow pls help me out
Dear frend I need to have link for purchase double system Driver card
Thanks
dude your smart no cap lol
It has to be red at the start
Okay I have another board will not power on when I plug the charger cord in it turns green when I plug it in to the hoverboard it stays green what could that be
And it's definitely not charged no lights come on at all except when I first plug it in it say your hoverbord is ready to pair
My hoverboard is not charging
hi I’m new at your TH-cam videos
I need just like that Bettry how much plz
Can you tell me where to get the gyro mines broken
Naku Over Broad battery kavali sir
❤❤😊
omg...
thank you sir for saving my dollars.
an old mode
Hi sir mosput HY 1908 enqlet Nomber how??
