- Hi, here we have a broken digital inclinometer. It was sent in by John, who used to use it for work before it failed, and just displayed all the digits all of the time.
Let's take it apart and attempt to repair it.

Spoiler Saver & Riddle
Question: If you go to the cinema/movies and you're paying, is it cheaper to take 1 friend to the movies twice, or 2 friends to the movies at the same time?
Spoiler Saver & Answer.
2 friends at the same time. You pay for 3 tickets instead of 4 if you went twice with 1 friend. (Unless the movie is sooo good you want to see it twice)
Thank you👍👍
Take a camcorder, then all your friends can watch it 😂
Two friends at the same time, you only pay for one taxi that way.
your still paying for yourself twice
Nice one Vince, I’m annoyed that I didn’t see the problem though (I didn’t look too hard though to be fair). It went with me to many places in a backpack so had a quite tough life 😂
Thanks John, it is a lovely little device with amazing accuracy. Cheers for sending it in 👍👍👍👍
You really got the measure of this one, Vince! 👍😁
🤣🤣
Always on point with the humor 😂
@@midinotes I aslo have to angle with you
@@Tim_3100 🕵👍💖💖💎
Interesting, looks like the angle sensor is capacitive. Looks very similar to how digital calipers work (bigclive did a teardown video for a cheap pair of digital calipers if you are interested). I would've figured they'd use a cheap accelerometer but I love how they went the mechanical route.
Thanks SJM, I will check out Big Clive's video 👍👍
The soldering on that header is horrible eee. (Not your soldering. The factory soldering). Its like they used no flux
I wonder how that product could even end up with such terrible soldering. It looked like the original solder hadn't even flown onto the pads...
Your desk is so much tidier than mine lol
You re excelling in fault finding, Vince. You were so quick this time!!
Those header pads were just bad from the factory. The pads underneath never got hot enough for the solder to flow onto them in the first place, hence the bubble of solder sitting on the top. I'd probably say it was hand soldered and someone just dabbed from the top and only heated the header pin.
If they'd have poked in from an angle, and put the tip of the soldering iron to touch the pad and header at the same time, it would have worked great with a decent "fillet".
I always tend to put the soldering iron on the pad, and just give it a little shaking / dabbing motion. You can usually see the liquid solder shaking on the leg, and you know it's hot enough and holding its shape from surface tension.
16:50 You can buy those switches, they are as you say dirt cheap, Or you can also get them from any number of discarded devices such as tv's, radios, printer, computer mouses, and so on, you would be amazed of just common these things are in modern devices, and how much of a weak point they are.
Its a Encoder not a Potentiometer.
Potentiometers aren't very accurate, they wear off over time and they have too much friction.
You can use a Encoder to control a Electronic Potentiometer and that is most likely what they are doing.
Electronic Potentiometer is a Chip that can change resistance when they receive the proper signal with and they do it with high accuracy.
I am "inclined" to watch this video.
So cool, I use one of these on my table saw and it works great, but never knew how it worked. Figured it was a more "digital" sensor inside it!
Must admit I was tearing my hair out watching you beep out that switch !...cheers.
10pm.
Feeling like doing nothing.
And MMV video in feed. Cheers, youtube, and MMV!!
Hi Vince I've got a wireless keyboard with mouse built in my girlfriends candle exploded.... the wax has gone all over it luckily i had it insured with currys if you want it to make a video I'm more then happy to send it to you!
Investing in crypto now should be in every wise individuals list, in some months time you'll be ecstatic with the decision you made today.
Most intelligent words I've heard,,
Crypto is the new gold
I wanted to trade Crypto but got discouraged by the fluctuations in price,
I heard that his strategies are really good
@@marymiles7827 Yeah, first investment with Mr Gary Ralph earned me profit of over $25,530 US dollars, and ever since then he has been delivering
Whatever you post i always enjoy to watch you fixing...thanks for the upload Mr. Vince...love from Bangladesh 🇧🇩
Great fix =D I agree its going to be that stupid interconnect that breaks with any knock etc! Should be a ribbon connection to be reliable. I couldnt really see exactly how it works, but the circular traces around the weighted part make me think its detecting magnetic flux changes changes based on the weighted moving part maybe?
They do the same thing in those Xbox controllers... something that is bound to be dropped
I think that one works like the cheap calipers by using capacitor difference of the track around the weight. I did obviously click on the video and I always thought they'd be solid-state like a phone. I'm more inclined to buy one now, thanks.
Hey Vince good working there 🙂 yep COVID-19 RULES STAY AWAY FROM CORONAVIRUS 3 FEET? USE HAND SANITIZERS AND WEAR MASKS WHEN YOU GUYS GO OUTSIDE
I have one which you long press the zero on a flat surface to get in to calibration mode, you then turn 180 deg so the display points away from you and zero again. From that, it splits the difference giving you a true level. You can then use like an ordinary level. Or just short press zero to use as a comparitor. Great fix.
Thx, darling!!! Could it be that soft solder is proned for thermal instabilities so most of our current appliances need here'n there a retouch by a kind hand like yours to increase longevity! I see a goldmine in broken gadgets in our landfills utterly non appreciated by current consumer society not making time, that has no love to quickly puzzle over where the soft solder had become unstable, maybe when been exposed to suboptimal colder temperature. I truly enjoyed watching this EXPERT video!!!! Such an Adam is not a bomb dropper, not a war mongerer but a FINE SKILLER who has worked on himself + is enjoying it to share from his SKILLS!!!! Marvellous, which gives me hope that we have a case in front of GOD TO RESCUE OUR PLANET prior Global Nuclear War, the wrong sorts who are scroupellous are cheating the right sorts like you out of our species' right of existence....me being a medical doctor looking intensely for past 6 years why that is my species is acting out odd as nonhuman by breaking out all the time in uncontrolled masscriminal A (atomar), B (biological), C (chemical), D (drone), E (explosives) and N (nuclear) warfare that is the sort that has no love, no care for the other, the sort that snubs real life skills that is a good life skills not to harm the other. See my comments on other videos. You, 'My friend Vince' are a FINE ADAM, a homo sapiens + not a Borg, not a Neanderthal we need to breed out of us bia ?sexual = genetic selection? by sapiens Eves when we all raise our awareness for this voluntarily. You, dear Vince, are a real winner, a real keeper. Thanks to Vinces like him we have a right to exist me assessing our species 'schizophrenic behaviour' of human vs nonhuman. Pls check out his kind that even dives down to the deepest grave of the Atlantic Ocen, that us TITANNIC to investigate, sunk in 1912 that is 'real onset of WW1' with a massive torpedo hole mid of the haul in the National Geographic Video here on yt (you need to freeze the video around 1hr 14 min 13 sec or so to see the forensic evidence with your own eyes wrong sorts of the inhuman kind being war criminals flooded us with fake news now incorporated into our history books blaming wrongly as solely the iceberg). Our true Adam to rise for A SCIENTIST, a critical thinker who is unbiassed keeping wrong emotional judgments out if his mind but looks at a problem from many angles by playing around + testing even in admiration (many Eves can do that biologically, many Adams in an emotional tunnel brain of xenophobia + intolerance have a problem making then irrational nonplausible false conclusions or even worse flooding sensationally our media by LYING to us public). I applaude you having done a lot of professional training on your brain that comes with expert degree studies from university (ties) and many years work experiences nurturing critical collateral thinking skills!!!! It's been a real joy watching this video!!!! Love, Daggi. (PS pls check out too here on yt 'A tale of two brains' by Mark Gungkor)
Expensive, poorly manufactured device. $1 Ali Express item quality on the PCB lets down the entire device. It looks like these things cost in the $200-300 range. The manufacturer is getting screwed by its Chinese factory.
How long did it really take you to do??? I wonder how much LOVE'n CARE for us all to see....that is female curiosity me investigating you.🕵💖💖💖
The measuring part of that inside reminds me of an electronic caliper, metal moves past all those spots on the board and gives feedback. Probably very similar (if not exact) same circuit with a modifier to read out angle rather than distance.
Nice riddle. We love them at the fanclub. Great fixes Vince. Double faults are always nice to fix and what a great device. Every surgeon should have one to practice having a steady hand lol
Love these kinds of repairs on stuff I didn’t even knew existed 😝
Hi bud l got a job lot of switches from aliexpress if you want l will give you the order details if want them (they are all different types)
Seeing those blobs of solder sitting all sad mostly on top of the SMD pin header pins was quite tragic. Seems like they were only making contact between the pad and pins through sheer luck before. Definitely a QC issue at the factory.
Excellent video. I have one of these playing up so will now try fixing it.
Two questions though.
1. You use cleaning solutions. What are they and where can you get them from?
2. As mine may need to have a switch replaced you say you can get spares. What are the called and have you a link to a supplier?
Thanks for these videos they both entertaining and informative to the level you can see how to effect good repairs.
Kenny
Interesting that they went with the header connector instead of a ribbon cable. I would assume ribbon would be a lower BOM, and wouldn't have the precision requirement to connect the 2 boards. Maybe ribbon would introduce too much interference? I dunno, I'm no expert, but that's my 2 cents.
A very Massive Massive thumbs up Vince!!! Thanks for all you do.
Excellent, just sat down to tea, ideal time for some MMV repairs :)
Cheers Mike 👍👍👍
@@Mymatevince What a fantastic contraption! Never seen anything like it, but it's certainly a fine piece of craft inside there, that pendulem :) :) :)
I just want to make an overall comment I've been watching your channel since you first started and I love the Great content you create when you're doing your ( trying to fix videos )i be pulling for you to be successful it seems as though I I be more excited than you are when you achieve success on your repairs number one I also love your content because you explain things in great detail . I had a question for you that I was really curious about the question is how old were you when you start taking apart electronics and putting them back together successfully? I always look forward to seeing your videos you're my mate Vince with a lot of patience something I don't have
Potentiometer or encoder, to read the angle in a digital pulse? ABS and INC stand for absolute and incremental. don't know why that is stenciled on the zero button position.
hey where is the video where you are fixing the big red telephone back massager? It was some kind of massager that was red with a white cord and the head was white and you could twist it to set to different settings and stuff. I have a very similar back massager and the switch has gotten stuck! The cord also will need replaced. It is a great back masager with infrared heat and one of the relyable ones, I could use that video! The problem is I cant seem to find that trying to fix video anymore.
It uses a capacitive effect. You have multiple circuit traces that go "nowhere". When the half disk is near some contacts the capacitance between those contacts increases. By measuring the change in capacitance the device knows how far it's been moved.
hey Mate, it works like digital caliper like other said, it measures capacitance from different points, thats why there are traces and points along the measuring ring, actually very clever and yes.. it is very accurate as long as the bearing of the counter weight is clean and rolling good. very nice tool to have, you never know when you need one.
Pretty sure Vince would have his mind blown by a fidget spinner based on his reaction to the inside of this device.
ABS/INC is probably for absolute or incremental (relative to last position)
Didn't look through all the comments so someone else may have pointed this out. The brass spring strip you were wondering about should be pressing on the centre of the bob weight, either to hold it's position axially, to keep it grounded or to dampen the motion.
Well you wouldn't put it exactly on the blade because the blade isn't flat enough, but I guess this tool isn't for exact measurements
That factory soldering on those headers was really poor.
You can see that the solder hadn't flow properly.
Edited: check out "midinotes" comment. I believe midinotes is correct and my original thoughts are not.
I think, but could be wrong, that the difference in current detected through the position of the bearing/pendulum assembly is translated to degrees (angle) from the null point (zeroed point). Never touched one myself though (other than using my cell phone 😂). Great job as always!
Thanks HFR 👍
Mechanical! I thought these things have those “accelerometer” chips like in smartphones!
I know u wanna do a good job Vince but why do you waste isopropyl on already spotless things?
Nice fix. New tool to add to your collection. Cheers.
Great fix Vince, great to see how far you're coming with fault finding and honing in on the problems so quickly
It's same thing with capacitive sensing as in digital calipers but tracks are in circle not in line
These accurate digital measurement type devices use capacitors
Pair of legs are connected together within the microswitch.
nice one 👍👍👍👍
Thanks AR👍
Imagine if his smol laptop became faulty… lol
_wording?_ -> Angle of where One Stands on Tilted Planet.
Feeling a bit Different? - How One Stands on Planet, comparison of Tilt. %{\ lol
Vince's Placement on Earth compared to John's . . . What does Inclinometer read after Return?
could be fun, but i got _twisted_ haha _yeah, like i said - wording_ =p
Very unusual little device, interesting fix.
good stuff except for the lame dad jokes...
cold solder joint. someone has added solder to the pins when its the pads that needed heating.
those pads never ever took that solder. not very professional in the end.
i think the buttons go through holes in the metal and hits that thin metal strap
A GHOST!! How off kilter...
Nice one Vince - can imagine a lot of uses for this device
Hey bro what’s your insta gram
Do a broken coffee maker 👍 one of them pod things
abs / inc could be absolute and incremental
👍👍👍👍 just brilliant 👍👍👍👍
I have 3 or 4 of these. I use them on my bandsaw, table saw, jointer fence, and other things. I always wondered how they worked. I wasn't sure if they used a mechanical function, now I know. Thanks
I always wondered how these things worked. Been wanting to get one myself for my Mitre Saw. Nice to know how they work.
Nice fix as always.
Hi, Vince!
The sensing is actually capacitive, and works in the exact same way as the contactless finger tracks that digital callipers use :)
This is the one probably worn out by Bad Obsession Motorsport's Project Binky build.
👏👏👏👏👏
The red and blue but switch up
is this a tool used by satellite dish techs?
Could also be called a contact goniometer, which geologists use for dip direction of rock features (joints, veins etc), only watched this video because your presentation is so good!
Really spoiling us this week a calculator fix and now this 🥰
Love it. Thanks
Pro Tip: tape a bubble level to the top.
hey Vince love the vids
4:18 that’s what she said!
Are you really on the level?? 😜
I’m glad you did the summary part during the switch troubleshooting. Great video as always.
thats a gyroscope
13:40 i thin k he yawned
I want the next video for the does a new Nintendo switch already out
Jj
Was going to ask why those broken pins would affect the button's continuity, then came the voiceover. Well done!
7:25 hair reveal!
Hall sensors ?
I'll watch any thing you do because it's interesting to see the inside of things and the process of finding the fault and then fixing it.
Try to avoid holding button cells with your fingers! Battery life is reduced because you short it out and the acidic skin oils are corrosive (and reduce the contact surface). Holding them between tweezers will definitely short it out.
maybe only read out all the mmv names just once per month ? bit tedious on every vid.
I want one, just so I can look inside! Beautiful instrument !
What a smart bit of kit. Great repair vid, well done.
Thank you!
awesome little gadget that :) and fantastic fix vince :)
oopp
How do you film those close-ups and get the camera to focus correctly while soldering? Awesome job!
Btw: I think it is a hall effect sensor rather than a potentiometer.
I like the name of that tool, very fitting for the tool.
Good video Vince👍🙂
Here we go!
So glad this was a _professional_ inclinometer; I can't stand those "amateur" ones :)
