- Опубликовано: 6 сен 2024
- In this video we're going to be looking at a set of STIHL Bluetooth Ear Protectors. Someone brought these into our local 'Repair Cafe' where I volunteer helping to repair local people's items. Initially it was just thought they needed a new battery but this turned out to be a bit of a nightmare repair! Come join me while I battle to repair this....
I'm not an expert, but I do enjoy trying to fix things.

Amazing patience and another gadget saved from landfill.
Thanks Jonny 👍
" It STIHL doesn't work " LOL ! awesome marathon repair....cheers !!
😂😂😂😂Thanks Andymouse 👍
"One moment please..." Just like Big Clive puts it ;)
Yes 😂😂😂😂
Same 😄
@@BuyitFixit It has become part of the YT fixers lexicon. I have found myself saying the same. It is so appropriate.
Who's big Clive ? Do u mean tiny Tim and his large Ginger Beard
As i said to big clive--straight from Det. Harry Hoo of 'get smart' fame.
I would say that this repair ended with a certain amount of satisfaction, coupled with a large amount of relief! Well done, that must have taken a lot of patience, but thankfully well worth it in the end.
Yes, I think that about sums it up 😂😂👍
Before watching any further, I just wanted to comment and thank you for volunteering at your local repair cafe! Your skills are no doubt in great demand there. I volunteer at one also and a lot of the device that come through are devices I wouldn't see in my day to day work such as a Super 8 camera, a replica enigma machine, various computer printers, RC cars and so on. Keep up the good work!
Cheers Callum 👍Yes we do get a variety of things through the door, and sometimes I bring an unusual item home to do a video, or because it requires tools are parts that we don't have available at our cafe 🙂Great that you volunteer at your cafe too!
Damn, the Murphy's law was in full effect with this one, excellent job as always!
Thanks 👍🙂Yes, it was getting a bit of a nightmare this one. Reminds me of this bloody landrover that my wife has.. I've been fixing again too...
This gadget turned out to be "Beyond Economical Repair", but you repaired it anyways :D Well done!
Thanks 👍Yes, if you factor in the cost of labour (but seeing as I'm a volunteer at the repair cafe). The price of all of the parts together still actually worked out less than 1/3 of the price of a replacement headset. (£13 battery, £7 BT chip, and around 70p each for audio IC and charging IC) compared to around £90 for a replacement headset.
Dang! I know very few people that can maintain their patience long enough to complete a project like this repair without tossing given the nature of the thing, well done sir. You have a great set of skills and it shows in your repairs, thanks for the videos as they keep me thinking there is hope😉.... See ya soon.
Thanks Terry 👍
If those were on my healing bench they would have been repaired with the percussive technique and the non leaded hammer..
😂😂😂😂😂
Ahhh 3mins in my favourite chip ....a DW01, I don't know why seeing my initials on a chip makes me happy but it does 😃
😂😂😂😂👍
I’ve used and abused the same headphones as those for over 10 years and they’ve been great. Nice to see how they come apart incase i need to replace the battery. Nice fix !
Thanks 👍glad you found it useful 🙂
This is a great demonstration of how emissivity affects IR measurement; the label on the bluetooth module is greatly different from the bare metal around it.
Yes very true 👍
Well I'd have kicked that up and down the stairs with anger ten times over. I honestly don't know how you have the patience. Fair play to you I have had a lesson in how the headsets work 👍
Cheers SuperMick 👍
Your video got recommended by The Algorithm™ and reminded me that I really need to sign up to volunteer at one of my local repair cafés. There's 3 within a few miles of me after all. Decades of being paid to fix stuff, but for family and friends I never stopped. Thank fk that CRTs are pretty much unheard of these days, I used to hate working on them!
Nice 👍I've worked on CRT's too. When I left school in the mid 80's I ended up working in amusement arcades repairing video games and fruit machines. I also used to fix TV's for friends and family 🙂
Incredible perseverance, well done. I have a pair of these, I hope they don't go wrong! The problem is the USB charging lead supplied with them ends in a 5.5mm DC plug, so if you lose the lead you may try to charge them from a 12V DC wall wart, typically supplied with disk drives.
Thanks 👍Totally agree, not a great design using the DC plug. A few people suggested a USB socket but I'm not sure how robust that would be.
QUICK! Put it back together while it's working! 😅
Great job. 👍
😂😂😂Cheers 👍
I'm pretty impressed by the high end electronics Stihl used. Fitting BM20s in such a product is pretty crazy, I wouldn't have expected that.
Yes at least they didn't use generic Chinesium modules 😂
Well done, Mick! Another amazing repair. Glad to hear you are putting these well honed skills into use at your local Repair Cafe. I volunteer at two down in Kent. I agree the satisfaction of fixing stuff is amazing. Perhaps the Repair Cafe Org should have an Annual Awards so we repairers can pay homage to such talent. Hugely satisfying video, thanks again. Sharing the EEPROM dump too! Simply AWESOME
Thanks 👍 Nice! glad to hear from a fellow repair cafe volunteer 🙂👍
I'm going to be attending my second Repair Café a week on Saturday - not sure I'd have a hope with such a tantalising set of faults! Great job 🪛🔧
Nice one Mick, you have far more patience than i do!
Cheers Scott 👍
Is there a patron saint of fixing broken things?
Yes 👍It's me 😂😂😂😂😂
I have a set of Peltor Comtac XP which suppress loud ‘bangs’ but allow speech so are ideal for shooting. They have an issue with a constant ‘hum’ in one ear and make them unusable. They retail at £350!! Would love to have them repaired!!
You can drop me an email using the channel's name at out look dot com.
Nice repair ! And with lithium battery powered devices its common that the device is not turning on when it is in the charger. its a safety featue otherwise the charger will keep it charging above safety values.
Thanks 👍and thanks for the info 🙂
Wow impressive repair ! What a hack, never thought it was possible to transfer the programed one so easily (easy for you apparently).
Thanks for the share !
Thanks 🙂👍
complimenti per la tua perseveranza e pazienza sei un bravo riparatore bellissimo video grazie
Thank you 👍
Genius Mick, fair play to you, seriously. I'm blown away..
Cheers Marc 👍🙂
Wow, that's perseverance! Well done. I probably would have given up half way lol.
Thanks 👍yes, the owner was quite persistent that they wanted it repaired. It still worked out cheaper than buying a new one.
The video may have been long and tedious for you but what a fantastic diagnosis and repair video for us, your audience! Thank you once more for a GREAT video!
Thanks 🙂👍
You should build an SCR crowbar circuit on the charging input or at least put a 5.1V zener diode across it. The zener will conduct if the voltage goes above 5.1V and will short the charger. If the owner connected the wrong charger, they could do it again.
Good idea Simon 👍Thanks for the suggestion 🙂
Another excellent fix but with the new battery and all the components I'm thinking he should have brought a new pair.
Thanks 👍Yes it was one of those things where we started, and well.. one thing led to another .. oooh errr 😂😂😂😂 It still worked out cheaper than buying a new headset though.
That was a lot of damaged parts. Great job.
Thanks 👍
I suppose these days every device has software running inside it.
Amazing work verifying and transfering the flash chip!
Thanks Matt👍
Good work man! You've nail it! Cheers
Thank you 👍
Another amazing repair, and a good lesson as to why you really shouldn't design 5V products with barrel jacks these days, especially in environments where 12V (or higher) barrel jacks of the same dimensions are common. Sure, barrel jacks are more durable than USB connectors, but this isn't meant for use while plugged in, so that hardly matters. If these were mine, I'd finish off the repair by replacing the barrel jack with a USB socket to avoid future confusion.
Thanks 👍A USB-C might be better, although it might take a bit of work to make it fit. I think the owner knows better now, and I spoke to him the other day when I was looking at his electric scissor lift, and he said they were still working fine 🙂
Hi, if you look closely around 36:25 on the board of the stihl headset just behind the programmer, you will see that the board is already working because of the blue light blinking without the original chip soldered on the new bt board, 😉 Julien.
Good spot! I never noticed that! I wonder if removing the EEprom made it just switch on without any buttons being pressed? as I know in the settings you can configure which I/O pin is used for different buttons, and with no EEprom being fitted it would have defaulted to all 0x00 or 0xFF when trying to read.
@@BuyitFixitHi, i think the eeprom of the new board is still not unsoldered from it when you used the programmer to read the original eeprom, if you look closely, you can see it in the video, so i think in the factory there is already some files in the eeprom to test the board i presume, Julien. 😅
Yes I was thinking it would be programmed already, perhaps the I/O pins were configured differently as I know in the configuration program you can specify what buttons are on which pins, or what buttons are present such as FF or Play / Pause etc.
That was a Nightmare on Stihl street , Most all the landscape guys around here use those kind of ear protection and / or headphones , another one for the chalk board ..... Take Care Mon Ami...
😂😂😂😂😂Thanks Cajun 👍
Another outstanding job. That's going above and beyond.
It reminds me of Triggers broom in Only Fools and Horses, "Maintained it for 20 years. This old brooms had 17 new heads and 14 new handles in its time"... 🤣🤣🤣
It's the same headset, it's just had a new battery, a charging control chip, a new Bluetooth module, with the transferred flash chip, oh and two new audio chips...🤣🤣🤣
It's why I hate USB to bayonet cables, 'cos a lot of people think, well it's the same shape and it fits so it must be the correct charger for that...!!BANG!!!
If it's USB then stick a USB micro or a USC C connector in the device, then the user can use any cable they have lying around.
Thanks👍 and yes great point with the USB C. I had something similar with a bug zapper that my Daughter or her husband plugged the wrong charger in too (did a video on that one). It was also a DC barrel jack to USB...
@@BuyitFixit Fair play for sticking with it.
If I was fixing that there would have been a lot of expletives uttered.
really nightmare it was mate.All the best.Peter.
Thanks Peter 👍🙂
Excellent repair. Well done. The repair cafes sound great, it's a shame there's none in my neck of the woods.
Thanks 👍Did you check on www.repaircafe.org/en/ ?
@@BuyitFixitYes. There's nothing even close. The nearest is Middlesborough which is 45 miles away.
Shane 🙁
Great fault-finding (and determination)!
Thanks 👍Yes normally I wouldn't go as far as I did. I asked the owner what they wanted to do and he said pretty much just get it working... so I did 😂😂
You're the best👍
Always makes my Saturday routine perfect.
Thanks!!
Thank you 👍🙂
Lost on thought of "Expensive", until the Priceless end.
You're like *Louis & Clark's adventures;* Each step opens more discoveries.
Leap to unknowns; Search parts yet tested; Fear not ordered, nor delivered; Successful Journey once again. *Cheers!*
Thank you 👍🙂
Holy Chips (Blue) Matman, that was a bit of a conundrum and rollercoaster ride 🙂
Thanks Chris 👍
good repair and something else saved from landfill. Thanks for sharing.
Thanks 👍
Hi, many thanks for video.' Extortionate' postage sounds like RS .
You're very welcome👍Yes, Farnell and Digikey and Mouser aren't much better..
I like you because you share what you do, it's useful to me, hope it will be useful to those who need it, please make videos because it will be very good for people who understand mechanical engineering.
Thanks 👍🙂
Brilliant work. Seeing surface mount chips blown, I would have thrown it in the f*ckit bucket. 😊
Thanks Matt 😂😂
Just found you a couple of days ago and I'm loving your content.
Thanks 👍Welcome aboard🙂
It must have been a nightmare to do but it made for a very interesting video!
Thanks 🙂👍
How the heck are you getting chips "the following day"?! Lol, I have to wait a week from Digikey, then forget where I was in the project!
😂 i wait two. But from Mouser just 2 day
Farnell dispatched the day I ordered, and I got it the following. Digikey seems to be around 2 or 3 days when I order but I usually wait until I need a few parts to get free shipping.
Nice job, just started dismantling mine as they are switching off when I move them. I think mine probably have a break in a wire, expecting it to be where the cable tie is that stops the wires from pulling through the grommet or in the loop from the clipped in section to the grommet where they sometimes get caught and pulled off my head by tree branches when mowing. I've got them apart but it's late so testing the wiring is a job for tomorrow. Your video whilst not the same as my issue did give me a look at the internals to see what to expect when I finally pried the halves apart without breaking them which was what I was most worried would happen. It meant I could see the wiring connecting each side could be removed for testing and repair.
Thanks 👍I do hope that my videos are helpful to people such as yourself, so well done in taking the plunge! and good luck with your repair. It does sound like the wire. The black and red are the power wires that go from one side to the other so I'd unplug them from the battery side and see if you get continuity over to the other side.
@@BuyitFixit Thanks, repair worked and it was a broken cable, may have even been a couple more too as continuity testing indicated it was likely, but moving the cable to check for a break even with an extra pair of hands helping was tricky to do without disconnecting the tester probes. I've ordered some parts to make a replacement cable as it ended up with not much slack and the soldered repairs (I cut and joined all 6 cores to the same length), are a a bit tight for space inside behind the pcb.
Another great video, I'm glad you got there in the end. It gets expensive when you have to keep buying components especially with shipping costs, Farnell is ridiculous just for one or two items under £30 you have to pay £9 +vat shipping.
Thanks 👍Yes agree, I usually wait until I need parts for a few items before I order as then you get free shipping. This one was a bit of a nightmare as they were the only place that I could get the audio IC without waiting a few weeks.
That one had you running out for the mail a few times. Nice fix..
Thanks 👍yes, it did take a few more parts than I was expecting 😂😂
Fair play to ya, great patience that paid off great job..👍👍
Cheers Jimmy 👍
Really admire your perseverence on this one. For the money, whoever designed these should have put some sort of input power protection in place. Just a zener to clamp excess voltage may have saved a ton of repair work. Well done again!
Thank you 👍
Wow! we’ll done, awesome job. Was getting worried for you, with the cost rising chip by chip!
Thanks 👍Yes I was too 😂😂😂
it was at this point 6:13, I started thinking about Cybermen and Dr WHO, after staring at the power connector for a few seconds. It even winked at me.
😂😂😂😂👍
Barrel plug does not seem like a wise choice here. Why not USB??? Could have avoided this whole fiasco. Bizarre. I am amazed you fixed this one, well done
Thanks 👍Yes totally agree, not the best choice for USB!
That one sure was a challenge. It drives me crazy when I have to keep taking something apart over and over again. I would have to say, you have a lot of patience when it comes to that. Awesome repair! I haven't had that much experience working on IC chips, and using my rework station. I'm still learning how to use it without burning myself or everything on the board. Good thing I have a lot of scrap boards to practice with.
Thanks Ron 👍
Your an inspiartion to learn from Mick! I've recently been given a chance to repair obsolete electronics at my work and its very helpful to see your troubleshooting process!!
Thank you kindly Jake 👍
Simply amazing
Thanks a lot 😊
"Repair cafe" ... never heard of such a thing in the USA. What a great idea...
Yes 👍I've just had a look at there are quite a few in the USA! www.repaircafe.org/en/visit/
I've never heard of it either, I found that we have them in Denmark too. I might have to see if they need some help from another life-long tinkerer.
Great 👍I'm sure they will be pleased to welcome you onboard🙂
Serious perseverance there! I would have performed the last rites on that device quite early on.
Yes 😂😂😂I had already done that, but the guy was quite determined to see if it could be repaired even though the cost was mounting...
Very conscientious, well done. All that tech and no basic over-voltage protection. Presumably the Bluetooth is so you can listen to your Van Halen (smartphone in overalls) whilst using that pneumatic road drill. Ergo, ears protected.
Thanks Ralph, yes or to answer your phone, although I'm not sure how well the other person would hear you if you were using a pneumatic drill or something 🤔
Great fix, perseverance often pays off 👍🏼
Thank you 👍
@@BuyitFixit you're welcome, I really enjoy watching your videos because I know you will fix them and always explain the process and what certain IC's are for so very informative and helps my knowledge grow.
Excellent repair, nice touch changing the chip with the software
Thanks 👍🙂
Excellent work!!!
Thank you! Cheers!
Great video mate. You better stick with Milwaukee repairs, Still is too complicated.😊😊
😂😂😂👍
Top job chap👍👍 brilliant video
Thanks Darren 👍
A good thing you got it finally fixed in the end, or somebody would have being working with his fingers in his ears.
And taking a leak in the toilet would have been a real problem in that case.😏
😂😂😂😂Thanks 👍
Quite a bit of chips to replace this time! Good thing you bought the extra audio chip.
Yes indeed! We just got told that it had stopped working... I didn't realise the extent of the damage, but by that time I was already committed to getting it to work 😂😂😂
Gargantuan challenge, brilliant fix
Thanks 👍
You are awesome ✌🏻✌🏻✌🏻
If it was anyone else, he would have left
Keep it up 💪🏻💪🏻💪🏻
Thanks so much 👍really appreciated 😊
Next level patience Sir! Congrats :)
Thank you! 👍
Great job, bravo! Regards.
Thanks 🙂👍
Just for referens Stihl is a german brand and in Germany every color code you can find is completely backwards and weird. They mostly use Black or Blue as positive. and White, Brown etc as negative. and when they get a normal standard cable with black and red they invert it to go with the Black positive and then whatever the other color is on that pair it becomes the negative.
Interesting. Thanks for the info 👍
@@BuyitFixit no problem
Appears the only thing that survived the damaging charger event was the PCB and the ugly orange plastic enclosure.
Yes 😂😂I would have wrote it off, but the owner was determined he wanted it fixed.
Great repair, very interesting. You have excellent troubleshooting skills. Thanks for sharing.
Thanks 👍
Brilliant skill man
Should this item not, be more focused on noise cancelling,?👍💪
Thanks 👍Yes I thought it would be noise cancelling too. Perhaps the noise levels are too high or dusty for the extra mics? I'm not sure on that.
Fried chips for tea! Grand!
😂😂😂😂😂😂👍
Great repair! You do exceptional work and produce excellent videos. It’s a rare thing these days, especially here on Y-tube. Thanks!
Thank you very much! I do try to make what I think are decent videos with good audio and video quality. I'm glad that comes across 🙂👍
Great work.
Thank You 👍
Exceptional work, with a lot of patience.
Many thanks!👍
Another great video and I love your determination to get things fixed. I myself volunteer at a repair cafe and find most months I am the one bringing items home that either I don't have the time to fix during the session or other volunteers can't diagnose or fix. Keep up the good work and I look forward to upcoming videos. Oh and Big Clive's "one moment please" I find myself using at the RC along with StezStix & Northridge fix's "solid" and "better than factory" at every session 😂
😂😂😂😂Thanks 👍
The master of debugging buggers!
😂😂😂😂😂😂👍
Great fix Mick, I love your determination to fix things! Definitely wrong charger failure, just goes to show the avalanche affect, thanks for the upload 😊
Thanks Gary👍
@@BuyitFixit 👍
Is it something you can't repair , Sir, your patience is out of normal.🙂
Thanks 👍Yes there are a few things now and again, but it's usually not being able to get parts or it's too badly damaged like the Cricut machine I looked at.
Wow lots of chips all blown ater each other! If i saw this i would have just thrown it away because it would be not worth my time and effort. But great job repairing it and even putting the code on the new wifi module. Its nice that its from a trusted brand MICROCHIP that allows you to buy them and has a good documentation instead of the chinese JieLi/bluetrum chips without any data on them. Also you got lucky that the flash chip was still alive and allowed you to read data from it!
Thanks, yes I do this as a hobby. Realistically it wouldn't have been worth repairing if there was a charge for my labour 👍
Well done, logical diagnosis.
Thanks 👍🙂
awesome job .. love every minute of it ... adapt , over come .. hurrah
Thanks 🙂👍
Another amazing repair! I'd love to see what the total cost and hours clocked were!
Thanks👍. I'd probably say at least a couple of hours, the part's weren't actually that much. Battery £13, BT Module £7, and around 70p each for the Audio IC and Charging IC so £1.50 or so. total around £22 for parts. If you were repairing your own it would still be a very economical repair as opposed to buying a new headset at around £90.
That's one of the best repair videos that I have seen. Thank you , you have the patience of a Saint 😂
Thank you👍. I've done some pretty crazy repairs, that I think a lot of people would have given up on! A couple that spring to mind are the FLIR thermal camera, and the AVerMedia video capture device I repaired 🙂
I think it’s a design fault to use a barrel plug for a 5volt device. A mistake is essentially made. A usb port is more appropriate I think.
Yes I agree 👍
Epic repair as always!
Thank you 👍
Nice work
Thanks 👍
Wish you were in the USA 🇺🇸 as i have a switch mode power supply that is giving me fits it doesn't want to work i guess im going to have to replace the entire components on board
Take a couple of pics if you like, and drop me an email with what it's doing / not doing at the channel name at out look dot com.
