My parents are about to get a new TV because theirs is faulty and they don't seem interested in repairing it. I'm going to be taking the faulty one from them and, because it's ridiculous that the TV only worked normally for 3.5 years, am very tempted to try a repair. It's an LG CX OLED from 2021, here's a description of the issue:

• When plugged into the mains, the standby light will come on and the TV can be powered on and used as normal. However, if too much time elapses after plugging-in without fully powering on (I don't actually know how long, somewhere between 5-10 minutes), the standby light will switch off and the TV will become unresponsive.
• When the TV is in this "unresponsive" state, the only thing that will bring it back to life is to unplug it from the mains and wait a bit (again, somewhere between 5-10 minutes), then plug it back in and turn it on. This happens every time the TV is plugged in, with no variation.
• The TV is fully functional when it's turned on, and there's no other issues with it at all.
• If the TV is turned back off (back to standby mode), the clock starts again until it becomes unresponsive.

So clearly there's some problem with standby mode. Some searching has indicated that other customers are frequently having this issue, and that replacing either the PSU or Motherboard of the TV will solve the issue. It's out of warranty, so I'm going to be spending money if I want to fix it. Replacement PSUs are about $250, and replacement Motherboards are about $350. I can only really afford one of these parts right now, so it's a gamble if I can't figure out a way to isolate the issue to one of the boards. I don't own a multimeter to test power, nor do I know anything about electronics, so I'm slightly fumbling around in the dark on this one.

There's always the alternative of getting up and switching the power on and off every time, which is significantly more convenient for me than it is for my parents because of room size and outlet placement, but I'd like to be able to use the remote as intended (and, as I mentioned before, it's ridiculous that the thing is falling apart after only a few years, it's a very expensive TV!). I could also... find an IR controlled outlet or something? I don't know if that's a thing, but you know what I mean.

I will end up using this TV regardless of whether or not I can get it fixed, because OLED is unbeatable, and it's not every day that my parents will replace something that isn't outright destroyed, but if you have electronics experience, or have had this problem (it seems like it's super common) any recommendations or help would be appreciated!

A while ago some of the keys on my Dell XPS laptop started working poorly, they were only registering the presses half of the time or if I pushed them really hard. I tried removing the keycaps and cleaning the keys on the inside, but to no avail. Well, I thought, that means it's time to get a new laptop. So I was choosing the next laptop to get. One of the options I considered was the Framework laptop, which is supposed to be super repairable - I mean, if only I could just replace my laptop keyboard, I wouldn't have to buy a whole new laptop just because of a few broken keys!

Then I thought about it again. I realized that a repairable laptop is only useful if you actually try to repair your laptop, which I've never done. So, I looked it up, and turns out Dell, while obviously not as easily repairable as Framework, has very well-detailed official service manuals as well!

Two weeks of waiting for a Chinese copycat keyboard from AliExpress and three hours of work later, I finally have a fully working laptop! Turns out it isn't hard at all to replace a broken keyboard - but I'm still very proud of myself for doing it, mostly for even deciding to do it instead of just turning a fully functional laptop into e-waste as I would've done otherwise. I was also really surprised that Dell laptops are that easy to fix (though they don't officially sell replacement parts to consumers), since it's known to be a company that makes a ton of money on expensive support offerings.

I don't really know what the lesson of this post is, I just wanted to share this small achievement with y'all.

Hi Tildes, I would like to share a DIY backpack repair I recently completed.

I have had the LTT backpack since it was launched. It has been incredibly durable, but I have used it so much that some parts wearing out is to be expected. I got one of the zipper replaced through the warranty, but the bottom of the back side was wearing out too. Here is a picture showing the damage. The white fabric sticking out is some internal padding. The stitching didn't come out, the black fabric just wore down enough to start disintegrating. Right after that picture, I secured the worn edge with a simple whip stitch to prevent it from falling apart more.

I considered a few different repair methods, but nothing seemed too appealing. I considered trying to learn how to darn for this repair, but I thought that I wouldn't like the edges of the darn patch. Also, the fabric in that area was so thin that I didn't think it would hold a direct darn repair. I also got a quote from a local repair shop, but they wanted to just cover the area with a new piece of fabric, which wouldn't have looked good.

Around this same time, I bought myself a cross stitch kit for Christmas, to pass the time on the many train trips I was taking. I got quite interested in the hobby, and that got me thinking: maybe I could make a cross stitch repair? Cross stitch isn't very durable, or used for repair, but if it only lasted a few months, it would at least be a fun project.

At first, I was looking into simple cross stitch border patterns like this one. I ruled those out simply because most would have been too tall for the repair I was hoping for. I also liked the idea of creating my own pattern. Since it was an LTT backpack, I wanted to keep with the tech theme. I was also inspired by the dbrand circuit board pattern that was released around the time I started this project. I liked how it evoked the design of a functional circuit board. So I decided to make my own cross stitch pattern.

I eventually came up with this pattern. I liked the idea of the central chip being rotated 45 degrees, since many geometric cross stitch patterns focus on 90 degree angles. I also wanted some different symmetries in different places. The traces connected to the central chip are rotationally symmetric, then a dissimilar patch, and then mirror symmetry traces after that, and dissimilar edges. The left side was meant to represent a USB or similar port soldered to the board. The right side is a wireless chip, with a PCB antenna.

For anyone who is experienced with cross stitch, there is already some unique features of this pattern. Cross stitch typically deals with complete X stitches, shown as pixels in the pattern. My pattern has a bunch of partial stitches, where the X has half of it with a different color. I wanted to use partial stitches to make what looked like thin PCB traces without having everything be 90 degrees (and 90 degree angles are a big no-no in PCB design). I also have some singleton stitches that are off the standard grid for the rest of the piece (supposed to represent vias).

Next for the materials. Originally I considered metallic filament. It is shiny and sparkly, which would fit in with the PCB aesthetic. However basically everyone on the internet says that metallic embroidery filament is incredibly annoying and difficult to use, and that it should be used sparingly. Then I stumbled onto DMC étoile, which means star in french. These are standard embroidery filaments that also have a plastic sparkly thread with the cotton threads, so they give some sparkly effect without being too loud. The effect is quite difficult to see on camera, but looks very good in person. I also decided to use 28 count linen in black. (The internet also heavily recommended against using black, and it definitely made the stitching experience more difficult.)

Et voilà ! I think it came out absolutely fantastic. Also, bonus pic of the back so you can critique my stitches. The partial stitches weren't too difficult once I got the hang of it. I buried the start and end threads under as many other stitches I could for extra strength, and didn't cut/restart stitches if possible. I also experimented with different floss thread counts, but I decided on 3 instead of the standard 2. Then I washed it and applied an iron-on interface backing material to try and keep the floss from coming out.

Finally, after a few months of having my backpack in the repair shop for the zipper (long story), I had it back and could try and finish the repair. Sewing it on was surprisingly difficult, mostly because I didn't have access to the back of the work piece. I managed to get a sloppy stitch in that would at least hold it in place, and went back to add a secure whip stitch with a curved needle and double thread. But I think it came out very nice. Final picture 1, and final picture 2. The black fabric doesn't exactly match the black of the backpack, but it isn't too noticeable in person.

And now I have probably the most unique LTT backpack in existence!

So a my building charged me for a clogged toilet repair that turned into a total replacement.

Its listed as a plumbing damage charge, I don't believe they have a basis to charge for that. What should I do?

Also my insurance company interestingly didnt renew my tenant insurance policy ive had fot years with no change.

Should I ask them to provide the documented charge and consider filing a claim with my insurance seeing as they're dropping me anyway? Should I ensure I have a new policy before I file that claim

Not proud but proudly not ashamed

Just something I was frustrated by ever since it became increasingly common even outside of smartphones and tablets.

For a few years now I increasingly see basically any battery powered product having mostly internal accumulator options(aka proprietary battery of uncertain ability to replace), especially in more expensive items in the category. Why?

I mean do see several advantages from the business side, I simply have no idea what advantage would there be for the actual user.

I could see it if the batteries had comparable lifespan to the product, which they most definitely do not unless the item is of truly bad quality.

This is a community I've missed since leaving Reddit, but I didn't expect to find or create such a /~group here given Tildes is a much smaller community (I figured, statistically, there wouldn't be enough users with overlapping interests in Right to Repair / Electronics / 3D Printing / Makerspace / etc... for such a community to be present or to naturally form here.

With the recent post asking for advice on a soldering station, and the number of users that participated in that discussion, I've been rethinking those assumptions of 'not enough users / not enough interest'. Then I further reflected on the significant number of people we have here that have fluently discussed other technical areas such as Linux, Programming, servers / Homelab topics and I realize upon reflection that a fair many of our users here are pretty high on tech literacy...

So, as a prelude to requesting a new group like /~electronics or /~makers or some group name along that philosophical theme, I wanted to ask the community at large first as to how much interest there might be in this.

Do you, dear reader, have an interest in electronics repair? In a garage workshop or other space at home where you fix or build things? Makerspace topics like 3D printing? Right to Repair law? If you want to know how to replace your cell phone screen, or ask about soldering or Raspberry Pi or Arduino, are you interested in having a place here on Tildes specifically for these things? Please, if you have such interests, let's discuss here.

Pinging those who participated in the soldering discussion:

Does anyone here have any advice on repairing a book spine? I have a hard back that an excited puppy chewed off the outer part of the spine. Now that said puppy is well out of her "chewing on random stuff" stage I'm trying to figure out how to repair/reinforce the binding since it's otherwise a brand new book. I'm a crafty person so I'm trying to embrace the accident and treat it as a book with a bit more character.

Most of the glue is intact, so my current thought is to add additional glue (book binding glue I'd assume?) and then use a tape or fabric to reinforce the spine.

I'm not expecting a repair that looks like new. I'm looking for something functional and durable that will keep the book from falling apart with use. If there's a good tape for this application that would probably be sufficient. Just soliciting some additional feedback in case someone has done something similar before I take a stab at the project.

Here's some pictures of the book and of course puppy tax: https://postimg.cc/gallery/wyskQn1

So this is ultimately a very oddball situation. Some background:

I live in a rancher in southern NJ. Fully electrified home.

I had recently installed minisplits to replace some electric baseboard heaters, covering about 2/3 of my home. This was fortunate, as I believe my blower fan in my central AC unit blew out. The minisplits + 1 window unit have actually been cheaper to operate than the old AC unit, so now I have a vestiegal high-velocity central AC system in my attic.

Namely, this means a lot of unused flexible, insulated ductwork and some ferro-fluids in my attic that should probably be blocked off and drained, respectively.

I've been contemplating on how to possibly repurpose some of this stuff to fix one of the biggest blind spots in my home: ventilation and filtering

My one bathroom exhaust fan vents directly into the attic, which is a moisture hell that needs solved.

There's no other ductwork in my home, and pretty much the only time fresh air gets in the house is if we crack windows or open doors.

So the theory is:

I route the bathroom exhausts into the old air handler coils to help capture the moisture and drain it out, then have it mix with some outside air and recirculate it into the house again.

Alternatively, routing some of the air between the attic/crawlspace/attached garage for preconditioning outside air as as well.

Is this insanity, or a remotely plausible idea? I'm fairly handy, and since its sbeing made with vestigial bits in spare time labor cost is much less of an issue than parts.

Came home today and found wet clothes in the dryer. Which was weird because earlier, I had found the same load in there wet and just thought I had forgotten to start the dryer. Low and behold, when I stood and watched it, about ten seconds after starting it, it started beeping and gave out an F01 error code.

While googling it, it seemed that the code meant the relay electronics board had failed and needed to be replaced. I thought, I can probably do that, but the board seemed to be more than $150, which is more than the callout fee on our home warranty ($125). But what we most needed was a working dryer!

While looking for the exact price and a source to order the board, I found this video describing a simple fix for a blown solder connection. I unplugged the washer, opened it up, and the board was blown in the exact same spot as in the video. I soldered a jumper in, put it back together, and lo and behold, the dryer runs!

I have an undergraduate degree in electrical engineering, even though it hasn't been my day job in a long time. So I could at least evaluate the plausibility of the fix, and I had the tools and know-how to do the soldering. So definitely not a fix for everyone.

Money is tight right now, so fixing the dryer for $0 (and in half an hour no less) was big for us. Sometimes you need a win, and today was a day I really needed one!

What fixes around the house are you most proud of, saved you some money, or kept a piece of equipment out of the landfill?

For the past 5 years or so, Ive been using a Samsung J36v as my primary mobile phone. I mostly bought it in the wake of my CDMA based dumbphone being, effectively, bricked by verizon shutting down the 3G network in my area. It wasnt my first choice, but it was dirt cheap and served my needs well enough.

However, the last couple of months, the microphone has just... died. Got quieter and quieter, until now I need to plug in headphones in order for a person at the other end of a call to hear me, let alone understand me. I think I need a new phone.

While Im not a fan with the software side of my current phone (locked bootloader, loaded with bloatware from the factory), I rather liked the hardware, as it had a swappable battery (like, not just easily replaceable, but swappable with only ones fingernails), an sd card slot, and a 3.5mm headphone jack. All of these features are ones that I regularly use.

Because of this, anytime I look for a new phone, they just seem like an expensive downgrade. I dont care too much about the SOC performance so long as its reasonably modern and can be expected to be usable for 5ish years. (I dont do gaming, YT watching, etc. Just signal, discord, call, text, and gps navigation). The things I do care about is a user-replaceable battery (screws are fine, but no solvents or heat needed), the ability to install either stock android or lineage-os or /e os (to get rid of carrier bloat), an sd card slot and physical SIM card slot, and a 3.5mm headphone jack.

However, I havent been able to find anything on the market like that. I tried the pinephone a year ago, and while Im a competent linux sysadmin, I was never able to even get MMS texting working reliably, and calls would not always be received while sleeping. Ive been reluctant to try other phones since then due to being afraid of spending money on something that wont work. At this point, its seriously affecting my mental health, as I go into a bit of a panic attack whenever Im reminded of the fact that my current phone is failing.

So Im asking for help. Ive compiled a ranking of the features I need/would like on a new phone, ranked from 'wont even consider a phone without it' to 'would be really nice to have, but I can still use it as a phone without it'.

Must haves (not an option without it)

• Needs to run some form of reduced-bloat android. I use signal and discord to communicate with my network, and while I could give up discord, only using it in the browser or desktop, I cannot give up signal.
• Needs to have a user replaceable battery. Doesnt need to be hot-swappable or anything like that (though that would be awesome), but needs to be replaceable without having to break the screen. (so, no requirement to break adhesives to replace the battery)
• needs to have a physical SIM card, and be carrier-unlocked. Me and my wife will be moving overseas in a year or so, and I will need to change carriers during that move.
• Must be able to use both USA and EU 4g bands. (for same reason as the SIM card)

Really, really nice to have

• Sd card slot. I dont stream music, and have a rather large collection of music on my home server. The storage space to sync that to the phone for offline playback would be a massive plus.
• capable of running a degoogled andriod version. While I could make do with stock google android (at least I wouldnt have the 'official nfl app' force-installed on me), it would be really nice if the phone was supported by either lineage-OS or /e OS.

Nice to have

• a 3.5mm headphone jack. I have trust issues with bluetooth, never had a BT device that worked reliably. I want to keep my copper wire headphones in use, and having to choose between charging the phone and using a DAC dongle doesnt really cut it.
• usb-c charging. Yah, usb-c is nice, but its actually less of a concern for me than the above categories. My micro-usb on my current phone has lasted 5 years, so I wouldnt be too fussed if my next phone used micro-usb.

Hiya -

I'm looking for some help because despite a lot of Google quality time, I'm sincerely struggling to get a solution.

I have a Plantronics 4220 wireless headset that I use for work (and also to connect with Bluetooth to my PC at the same time between calls), and somehow the audio is starting to flake out. It's like it only gets audio in one ear, but if I tilt my head slightly it'll get into the other ear or sometimes both. Pretty weird... it's something I might expect from a wired headset where the cord itself is dying, but not on a wireless one like this.

Anyhow, I'm very comfortable with tech stuff (building my own rigs for like 20 years now), but I've never really felt comfortable about iFixit kind of solutions where tools or hardware is involved with the hardware. I'd pretty much just rather throw a little money at a pro who can fix it in 5 minutes and charge me $50 or whatever, lol.

However when I am going to look for places that might offer repair services, all I'm getting are locations in the US... but I'm in Canada. Specifically Ontario. Anyone have a source (from personal experience or otherwise) on how I might best look up a place I can get this fixed at? Figuring out what to search for on this subject seems oddly arcane!

I recently went into my attic and pulled out my old 1990s 4-track Fostex X-26 tape recorder. I was hoping to transfer some of my old band tapes to the computer. Alas, it is dead. While it turns on, the motor appears frozen, and the device hums. (I don't mean there's line noise when you plug a speaker into it, I mean the device itself audibly hums, even when not using the tape controls.)

I have seen online that some people repair theirs. It's probably beyond my skill level to do so, though. (And I don't really want to do it myself.) I have contacted a few shops near me (Los Angeles), but have gotten no replies, unfortunately. I was wondering if anyone here knows of a good shop that would repair an older device like this.

I have also contacted some places that claim to do cassette to digital transfers, but none have replied to my questions about whether they can deal with a 4-track recording. Also, just looking at their prices, it seems like it would cost significantly more to have them convert my tapes than to get the recorder repaired. (And I'm not sure what's on all of the tapes, so I don't really want to hand over some embarrassing practice tape or tape containing some out-of-context banter between takes on it.)

I've looked online for a used one, but all the listings I've found have been "for parts only", which is what mine would be if I were to sell it. And knowing how these things go, they probably all have the same broken part. So any recommendations are appreciated!

Some days ago I came back home to visit my parents during these holidays.

Yesterday evening, while we were watching a movie, nature called and I had to go to the bathroom. Because I'm a lazy bozo and it is closer to the living room, I did what no man should ever do - I used my parents' bathroom.

Stumbling in the dark in this unfamiliar place I had no right being in, I clumsily bumped on the towel rack (an old 80s coat hanger looking thing) and to my horror, managed to snap one of its plastic arms off.

Because it's a relic of its time, and perhaps because the bathroom is a sacred personal space which should never be altered if not for strictly necessary reasons, mom and pops were upset.

I felt like shit, an outcast whose madness lead an entire family to despair and misfortune while trying to save himself literally a handful of pitiful steps.

But a shining beacon of hope came from a fading memory, one which sounded utterly absurd, yet in times of desperation still came out as somehow plausible.

"Just use baking soda and Loctite forehead"; this had been uttered from a German friend of mine while he had been admiring the broken mess that is my duct taped ps4 controller some time ago. Was it a joke? Was it a serious suggestion? German humor is often lost in translation...

Still, I had to give it a go. I had to try something. And this morning an attempt was made.

I'm still feeling ecstatic. Never have I hever felt this good about a DIY tryout. I can confirm that baking soda is an incredible catalyst for super glue; the result while somewhat sloppy-looking is rock solid.

Pops couldn't believe his eyes when he saw his good ol' towel rack hanger thing stoically standing where it always did, in its rightful place, with no defects at all.

Thank you baking soda and super glue, you saved Christmas.

To all of you whose plastics need some fixing, remember this combo and give it a go - it will save you as well.

Any other similar hacks that you might want to share are very much appreciated.

TL;DR
Baking soda and regular superglue are incredible for fixing plastics.

Edit: forgot to put tags in post. Apologies.

So we have had this popcorn machine for ages and just recently it completely stopped working. Being a fan of bigclive on youtube I though why not try fix it and maybe get a sense of how it works.

The guts

The insides honestly are pretty underwhelming - both the impeller and heating elements are quite small considering it only takes a few minutes to make a bowl of popcorn.

Circuit board and Another shot

Considering how few components there it was not too time-consuming to draw up a diagram. Please excuse the crude drawing.

From what I can tell it uses a bridge rectifier with a some caps to convert DC and even out the signal - and what looks like two resistors to further drop the voltage to the motor, maybe two offered better cooling? idk why they didn't use one. It's also kind of interesting how they used two separate coils for the heating with one of them in series with the motor, that will drop the voltage right?

They also have overheating protection here, with a an sefuse and a thermo switch, it actually has the piece of metal and a contact that will bend away when it's hot, I've only seen these in a textbook. Not sure why there are two types of thermo fuses?

The fault

Finding the fault ended up being quite easy, the main heating coil that comes off blue wire had melted. A piece of corn, oil, bits of salt or a mixture had found their way in and somehow melted the wire in multiple places. It cut the circuit so not even the motor was working which was my initial though when it stopped. I wound some solid core wire around the two ends, hopefully it will not unfurl or melt in the heat.
