Definitely flood damaged, pretty sure you can get a refund from eBay since it wasn't in the description.

If I had bought that I would have returned it for a refund the second I saw the corroded wheels. The item received clearly did not match the photo or description of the listing. It was clearly false advertising.

For the protection of all us honest ebayers please report these guys! I’d have had my money back from about a dozen items in your videos so far! You’re too nice a guy vince! 😉

With brushless motors (three wire) you just swap any TWO wires to change the motor direction.

i enjoy your channel, because it shows, that somebody with no pro-skills and just interesse in diy , can fixup almost everything. you give the finger to the lazzy people

I'm so glad that you're VERY thorough with these repairs!

I have so much admiration in your ability to never give up. Perseverance. That's a trait I wish I had. But your videos inspire me. Really. I've only fixed a few things, and abandoned too many other things, but I may have to revisit. Try try again. Thanks Vince. You've inspired me to never give up, even in life stuff. Thanks, mate!

First off, this does NOT have Bluetooth as one other commenter led you to believe. It's a 433/868 MHz remote control so you can turn on/off the board - i don't know why you would like to do that, but it exists. The control mechanism is a follows: The rubber parts stick into an optical interrupter (the fork like black part on the PCB) where the rubber/plastic part breaks a light beam, telling the board that you stepped on. It has no pressure sensors at all. The actual control mechanism is an accelerometer in each side. It's a small square chip with no pins, probably an MPU5060 or similar. It measures the gravity, and when you tilt the board with your foot, gravity readings change and it runs the motor.

Your positive attitude, tenacity and determination are amazing. Well done mate. 👍😎🇬🇧

I really enjoy watching you work. I love doing this sort stuff myself. I learned a lot form just watching you fix it. I would like to see you do more on you fixing these. As well as other stuff. :P

My MATE Vince you are lucky to always be making videos of thing I have to fix! It's amazing how lucky I am I guess. Thanks again!

I would get myself an ESC (Electronic speed controller) and a wireless receiver/transmitter and build an RC car or a robot out of those wheels. Also... It would be a really good idea to have an ESC laying around if you are going to be troubleshooting motors.

Great video series - doesn't matter what you decide to work on -- I'LL WATCH! Enjoy your sharing of your thought process while working on how to proceed. Also, how you correct where you might have been in error.

I giggled so hard when you said "knobbily bits" only because when I worked at Sears Hardware (here in the US) 13 years ago, I had an English lady come in looking for new lawn mower tires because the knobbily bits had worn off them.

Love watching ur videos. I loved taking things to bits when I was younger to try and fix

I always love your trying to fix videos ❤

the item looks pretty new I think it's probably been in a shipping container that's got flooded with sea water I would give the eBay seller really bad negative feedback.

I cant imagine how many intros you've started and then you open it and its the newspaper or something lol

Well done, you kept with it and that is how you learn

This was awesome buddy. Really enjoyed cheers. Reminds me of how my dad used to take my broken toys apart and figure out how they work

Just amazing, watching this and seeing what you where given for your money, I would have thrown that out. I need to rethink how I'm looking at thing. Thank you for the insight. I subbed and will keep watching for sure.

I really like this videos! Keep the great work!

Test it with a ohm meter, That might actually be a three phase motor possible either Delta or Star connections, Optic senser like what is inside a optical rotary encoder.

That seller (or associated sellers) has sold a number of these (and has had corresponding number of complaints on the sales). He or his/her associates is/are still listing them! Clearly not mail order returns but more likely from a consignment of units from a water damaged ship's container bought as a job lot.

Over a hour of Vince ill get the popcorn

I stopped using eBay when it stopped being an auction site and turned into a scam site 15 years ago. Around the time eBay purchased PayPal. I buy from Amazon as they deal with scammers quickly and effectively.

Those two parts that look identical from both sides look like huge electronic speed controllers with a little extra on there, maybe accelerometer or gyroscope and some other unknown extras. My brushless quadcopter motors have a similar 3 connectors on them, one for each phase of the motor. Typically the brushless motors like the wheels use are water proof and can be simply rinsed out, with the bearings being the main part that can cease up from water or other damage. If you can clean out that other wheel and change the bearing, it may be salvageable. Corrosion is the other enemy of brushless motors though.. Honestly I'd try to get a refund. I understand it was a no refunds sale, but it was false advertising / lying when it stated over 100 pounds in spare parts and I think that would be grounds for some kind of money back situation. Great video!

If I was you I would be doing some digging into the seller as soon as I seen the batters missing he could have removed them an he could be selling them on his eBay page. The seller knew what he was selling and he knew there was not £100 in parts get a refund and do some digging am sure you may find him selling the batters

:D Another amazing video!

I have a issue with my Segway as the right wheel sometimes doesn’t work and shake any suggestions?

❤ Waw great job Vince even though the outcome meant you had to right it off. Love watching your stuff cos I am an electronics service guy and I love the logic that you use in fixing stuff.

You can get an programmable module like a ardunio or something and make your own code for it, and wire it up to the motors and done, just a thought

brilliant video vince...i enjoyed every second.....thankyou for sharing

use a old bath towel or piece of carpet too take screws and things apart on. On hard surfaces things tend too bounce roll fall off of and get lost. Keep up the good work!

I just found one without the backcovers underneath. I dont see a power button, the battery has no juice. I dont have a lithium charger. I I need to try to turn it on, any ideas how? My lab power suppl.y is max 30v5amps

The Antenna/Aerial module is most likely for a remote, this is so they can be locked and unlocked from been used. May also be for a remote speed controller.

HI Mate, great fan of your videos. Just here to say that you don't need to remember the color combination of those motors. If its moving in the wrong direction then just swap any two of the connections.

Hi mate you said the boards were. Water damaged,I used to fix mobile phones, when a board was water damaged I used to use a 50/50 mix of distilled water and white spirit and put that in an ultra sonic cleaner then blow dry the board and that in ,80 of cases fix the damage it may be worth trying for those motherboards

Hi Vincent we purchased a hover board new and it wouldn't charge so we emailed as you do he sent through a replacement and it arrived sealed with charger and that won't charge either so where do we start charger works OK on the other 4 children's hoverboards

What do you do with the things after you’ve fixed them? Do you sell them? Do you keep them? Use them for spare parts? I must know

clean the board in ultrasonic bath and isopropyl alcohol.

It doesn't take a lot of water to corrode the insides of device. A small puddle can sit sealed inside a housing for a long time evaporating, condensing on colder metal bits, evaporating again, repeated until water from the reaction is used up or has left the housing. Water damage is going to be a common fault in consumer electronic repairs I strongly recommend studying the science behind it and techniques to remedy it.

Thank you for this video, it was really great. And little question, What is the name of the little computer that you use at the end of the video to show ebay?

Best to do by cleaning that corrosion on the circuit board is, to spray some alcohol on it and use a tooth brush, this has worked out for me on other stuff that ive fixed. Currently i need to fix my NAD Surround Reciver, but it will take alot of time to fix it as it has about 6 circuit boards. I also dumpster dive some times and i find alot of good electronics which still worsk or only has some bad components or leads. A few months ago i found a 1000W 48V scooter layin in my street, reason why they thrown it away was probably because the lead acid battery was dead. Ive tested the motor and lights and control board and its all good. It was also really rusted so i went and bought a multi tool to sand it down, also used an angle grinder to get the rust away on the bigger surfaces. You should try to get stuff for free aswell :P

works in the same way as a ceiling fan & its sat on 2 sets of sealed bearings use vasline on the bearings & along the outer edge of the windings

Great learning experience Vince!

this is a great vid !....learnt plenty and spares!.....well worth the money

what ,contraption' is it that lets you sit on the hoverboard? i want to buy that too.

You are absolutely correct vince, typically if you drop a phone or anything electronic into water, it is the minerals and other things in the water that make it conductive and thus shorts out the circuits, you could literally drop your phone in pure water with absolutely no contaminants in it and the phone will be fine, as for if the wheel would work or not i should think so as long as the little board in it wasnt touched by water, the windings are enamel coated so they should be fine.

The damaged part on the board looks to be a photo-interrupter. This is the same sort of thing you used to get in old-style (ie. ball) mice. If it's a compatible type (which it probably is as these tend to be fairly generic) then maybe you could salvage the part from an old mouse. These are a transmitter (usually an infra-red LED) and receiver (phototransistor) pair, and they have to be put in the right way round otherwise they won't work. Most have a part number on them and a quick google search should turn up the datasheet which will have all the info you need to get the right sort of part. In my experience, pretty much anything can be repaired - it's just a question of how much time, effort and money it requires. Good luck Vince, and keep up the great videos!

that blue tooth board is for controlling it with your cell phone and i have saved stuff in this shape i used brass brushes and corrosion X it will stop the rust remove the rust and help stop shorting of the boards

My first thought was flood damage - which would explain the smell. Is the postcode area one that had been subject to flooding at the time?

On the wheel you should pull the armature from the stator wheel there is only magnatisan keeping them together then you could clean the armature and stator with fine wet or dry and a drop off thinners then blow dry with air gun

Anyone know what the battery is for the segway/balance board.... thanks

Even my back is hurting when I watching you fixing the things on the floor Vince ! time to upgrade your workstation :)

My wife brought home a Rumba a couple weeks ago. The thing was abused. It had water damage from someone cleaning it by exposing it to water, the one motor was no longer working so when I tryed getting it to go, it would only go in circles. The bottom brush was missing, the side brush was worn out. It was a mess once I opened it. Since it was a gen one, it wasnt worth repairing. I do have the battery pack that appears to hold a charge and the charger and station. I may list them on E- Bay. The rest went in the junk.

Absolutely​ love these videos - best thing on youtube by far.

Does it move? No Does it need to move? Yes WD40

Thanks for the video👍On brushless motors you only have to shift two wires to change the direction of rotation..

Question Vince, don’t know if you had this happen with a Xbox, sometimes when I turn my Xbox on the light turns on for around 10 seconds then shuts off, after that it’s fine, turns on and works. I think it’s the hard drive because of the noises it makes. What’s your opinion?

my guess is it is a bluetooth module for a phone app for range and battery percentage

I have a phat ps3 that is broken do u want to buy it and try to fix it? It stuck in a firmware loop and the blu ray is broken.

Best KZfaqr out there when it comes to fixing things I swear XD

I like your videos when you open the things that you get on eBay

Great work and very optimistic!

1:09:00 you have put the wheel to far in so it is scraping the inside of the wheelhouse i did fix my brothers and his the 4 screws that attached the wheel to the bord was loose so first i did tighten them but then it made that scraping sound (probably why it did fling back the handle in 1:06:50) so i did take it apart again and loosen the screws and pulled the wheel out a little bit and then tightening the screws again and put it together and it did perform nicely :)

27:24 that unit is a Bluetooth connection for speakers

I love your mini tablet/laptop, what is it/where do you get one? :D loving the videos taught me alot and opened my mind to attempting my own repairs

the connectors are called XT60 and are commonly used on RC devices at the moment that kind of motor seems to be a brushless outrunner of somekind the rusty one for sure is unusable but the other seem ok just by look you might try and use it for some other project of yours ^_^ (p.s. in a brushless motor just inverting 2 wires will change the direction of the spin)

Hi, I love your videos and I have been subbed for a little while and I think you should try to completely disassemble the boards and clean them with a toothbrush and distilled water, after you brush them down rinse them with fresh distilled water and after that rinse them with a bit of isopropyl alcohol and leave them to dry for a while. If the mosfets or any other chips arent blown I think they should work and you probably should replace the bearings in the waterdamaged wheel because the water had to seep in thru at least one of them and you saw what it did to the metal insides, they shouldnt be expensive at all. also sorry for all the mistakes Ive done in this comment because I have no idea how to speak english since I live in the Czech Rep.

Great video Vince. :)

Hi Vince. Nice to see you struggeling..... good work... thats the way to learn it. I think that the opto-coupler sensors are only for safety.... you have to stand on it otherwise it will do nothing...the small wires to the motors are going to hall-sensors, magnetic sensors. If the motor is standing still and tilt the board a bit forward the hall-sensors detect that and the logic is steering the engine.... so.. i hope i gave you some usefull info. Suc6 with your channel.

Awesome tare down as always

Alot of these items are bought from catalogs or argos and because someone can't use it or did not like it They send them bk saying faulty so they get stored for months in boxes till the pallets can be sold in auction they are not protected well and get damaged a lot in warehouse

can you help me how to connect Arduino with hoover board wiring diagram and code for Arduino for speed control

Sea Water? damaged in shipping?

love your vids

someone might have bought it for parts, took the batteries out and resold it. those are some nice motor wheels Ive been thinking about buying a used one and make the wheels into a two wheel drive bike. theirs a video or two on YT where they drilled the hubs for spokes and made it work. though i think they used two or more battery packs. also WD40 is bad for bearings, it eats the grease out and will damage them.

You are awesome man👍👍👍

That black u shaped thing is just an optical switch. Same as used on 3d printers. They are pence.

What for Windows 10 tablet are you using?

you should start making your own carts and sell them to people as add ons for their balance boards. Looks like it would be a much safer way to ride them

I wonder if these are salvaged from a shipping container from a wrecked ship? It would seem to fit the water damage

I’m waiting for the day Vince does an upload and can’t get something working and just bins all his hard work.

Your patience level is GOD mode.

Hello young vince :) Crackin video again man, I just love how you get disheartened and then all of a sudden your attitude changes and Mr Challenge appears and on you go :o) sorry to your readers as this is in two parts and most of the txt will disappear but, yes, definitely conned and swindled :-( ... I can probably tell you exactly what happened. Every day in the UK abandoned / lost shipping containers are auctioned off, loads of em and very often there's good money to be made. I have a mate who does this for a living and he's bought 40ft containers full of stuff like Lcd TV's, Consoles, computers at the top end, but also less value suiff like cleaning chemicals, canned goods, clothing etc. He once bought a whole container full of nuts and bolts of every size. He could have put them into blister packs and made a fortune but no time so he sold it to another guy at the site and still made a good profit. ... Unfortunately, every now and then a container ship goes down and eventually the cargo is recovered by salvage companies and that's how they get to the auctions, the goods first being transferred to clean containers so as to not give the game away. Also, some container warehouses have been flooded by sea water, (your damage was definitely sea water ) or subjected to fire damage as recently happened in Nottinghamshire and in China. In this case, I think a few guys and girls probably clubbed together, bought a container at auction, probably not too cheaply, and got their fingers burned because if the boards were that badly damaged, then it's safe to say whatever else was in there was probably knackered too so to try and get at least some of their money back, the're offloading via online auction sites rather than put the goods through the high street outlet that at least one of them will own. It's cheap stock, good profit, gast return when it works, when you get caught out like this, you struggle to break even. :o( or so I'm reliably informed ;-) Hope that helps to blow the mystery a bit for you, looking forward to the next one :o) ...

Great vid 👍 I think a hair dryer, a few cans of wd40 and a few kitchen rolls. Think you may get lucky 😏

A quick tip, for Phillips head screws try to use the largest screwdriver head that will fit, it will be much harder to strip the screw this way.

really instructive and a proof that WD40 can do amazing miracles .Well done Vince

I'm wondering if damage was caused during shipping. Somehow sea water contaminated the product(s). I worked for a contractor at a major car company, no longer trading. I reported that a number of cars had faulty windows that were not closing fully. The batch was designated for delivery to Japan. The policy was to ship them with "minor" faults like this, and distributors would correct faults at the destination and charge the manufacturer. Unfortunately, on the sea trip, although the exterior was coated with wax to protect the paint, sea water flooded the interior through the partially open windows. The lot had to be returned to the UK for major rectification.

salt-water damage , maybe a damaged ship-container

whats the little laptop you use in the video?????

Do they really always beep everytime you move on them? 'cause that sounds like it'd be extremely annoying

it probably got wet, and they used one of those moisture eater things with a giant salt block - the vapor of that condensation is highly corrosive hence the white powder & smell

Those sensors with rusted pins shown at the one hour mark i think are called transmissive photo interrupters. You should be able to find replacements from your electronic component supplier of choice. I cant help you with what exact part you need but replacing those should be a lot cheaper than a complete motor controller thing if the rest of the components are still working.

@Vince that part that you broke looks like an optical sensor. Take a look at ITR9608. Should be easy to solder, though have a look if you can find the exact type of sensor (part number or similar)

This was fun!

That was cool!

Damn, I woulda filed a complaint through ebay/paypal for misleading, gotten money back. I can't see there being over 100pounds in parts ?

Refurbing batteries is usually pretty easy. You might want to explore alternative batteries or refurbing an old scooter battery.
