the OP photo shows the broken clips. this is a really common problem on these toyota hatchbacks, so if anyone has has similar issues you can do this too. all you need is some trim board retainers off ebay, a file set, and some super glue

break the clips off completely

use a file to file the plastic into a U sort of shape

file the bottom of the retainer clips on the sides and front so that they fit snugly into the bracket

superglue tf out of them, let it dry, and they work perfectly. all in all takes like 25 mins of work

i found this tutorial on an old scion forum that had like 10 views so thought someone may find this useful info

also my nails aren’t dirty thats nail polish i couldnt get off

So, I recently bought a mixing board and a powered PA speaker. I downloaded the manual for the board and it shows in the manual that you can plug in (in their example it's a reel to reel tape recorder) some sort of recording device. I circled it in red in the pic

I'm wondering if there is some modern piece of recording equipment, preferably mp3, that I could hook up in line. Like: board>recorder>out to speaker so we can play live and record it. Something that has 1/4 inch TRS jacks in/out.

I don't know a ton about this stuff and I know I can get a stand alone tascam style recorder, but surely this sort of thing exists, since it used to with older technology?

Over on his YouTube channel [Construction General] shows us how to convert a drain into a hydropower facility. This type of hydroelectric facility is known as a gravitation water vortex power plant. The central structure is a round basin which includes a central drain. The water feeds into the basin through a series of pipes which help to create the vortex which drives the water turbine before flowing out the drain.

To make the facility [Construction General] starts by laying some slabs as the foundation. One of the slabs has a hole to which the central drain pipe is attached. Bricks and mortar are then used to build the basin around the drain. A temporary central pipe is used for scaffolding along with some strings with hooks attached to hold the bricks and mortar in place for the basin. Integrated into the top half of the basin are fifteen inlet pipes which feed in water at an angle.

The next step is to build the dam wall. This is a bricks and mortar affair which includes the drain in the bottom of the wall and two spillways at the top. The spillways are for letting water flow out of the dam if it gets too full. Around the drainage in the dam wall a valve is installed. This valve is called the low-level outlet or the bottom outlet, and in this case it is a sluice, also known as a slide gate, which can be raised or lowered to control the rate of flow through the turbine.

Once the basin is complete and the low-level outlet is in place the scaffolding is removed. The basin is then painted, pink on the inside and white around the top. A turbine is constructed from various metal pieces and installed into the basin. The turbine is attached to a generator which is fixed atop the basin. The apparatus for operating the low-level outlet is installed and the dam is left to fill.

Asterisk because the article is nearly two weeks old at this point. NOAA 15 is due to be put into an “electrically safe mode” including turning its transmitters off tomorrow 12 Aug 2025 and NOAA 19 is to have its transmitters turned off on 19 Aug 2025.

RIP IN PIECE to the satellites that got me interested in radio waves and all things SDR. NOAA 18 bit the dust a few weeks or so before NOAA declared the remaining two EOL and NOAA 15, and 19 are fast approaching their end too. They have lived far beyond their intended lives and have been replaced with a bunch of stuff in the X band which is all microstrip and horn antennas, and high frequency stuff that I just dont really have the time to get into right now and besides, all the SDR’s that pick up that stuff are all thousand(s) typically and require actual programming knowledge beyond my ability to cut n paste. DIY antennas for that frequency band take more effort and talent than i have to make. Probably more money than I have too.

So anyway RIP to some real ones. If you are into that sorta stuff, better get that last pass or two in before they flip the switches. Im going to take my QFH and mount it on a giant wooden pole and go out in the road and record one more pass with an SDR and an old Android phone I have kicking around in my desk drawer for old time sake.

decided to include saveitforparts’s video about it which is where i learned about it originally, but posted an actual article about it too.

https://youtu.be/vA7yAP8f8zk

I've been stockpiling cardboard and bought the ingredients for the waterproof coating to try this out.

obviously comrades are down for whatever, but I think if we can get a decent system going for this, this is something even church groups would be into doing – in my experience, they really seem to prefer actually doing a thing themselves over just giving the money to the people doing genuinely helpful work.

an immediate issue I see with this is vulnerability to insect damage and flammability. I got some boric acid earlier this spring to make hornet traps, and reading that natopedia article taught me that it is used not just as an insecticide but also to make things inflammable, two incredibly useful purposes for this particular application. some of the comments of the video indicate that others thought of this as well, so I feel like this is worth pursuing.

are any of you chemists or otherwise have knowledge that would be helpful for figuring out how much boric acid to add to this mixture as a starting point? I have some applications around my farm that I can use to test the insecticidal part, and obviously the combustibility is easy to test. I just have no idea where to start with an effective amount to mix in without completely fucking the other necessary attributes (spreadability etc) of the mixture.

Some brands do different sized ones. Irish Dingle Gin do narrower ones if you're a comrade in the 32 counties.

E: From more reading, it looks like some kind of mineral wool will be the best thing to place between the studs. I also feel content adding MLV to the bathroom-side since the waterproofing underlayment for the shower is also effectively a moisture barrier. That way, any moisture-allowing failures can still permeate out the exterior wall and to the adjoining rooms.

As the title suggests, I want to soundproof my bathroom. It is right next to the kitchen (top hangout space) AND my disabled (relevant bc this is the only accessible bedroom) uncle's bedroom. We want to hang out and be able to use the bathroom later than my uncle wants to stay up, but the noise is bothersome to him. There are demons in his colon, too, which do not complement breakfast.

We live in this huge, cheap, almost-down-to-the-studs house that I bought so the only practical limit to renovations is money. How can I soundproof the bathroom? Right now it's just old lathe between his room and the bathroom, and the bathroom and the kitchen. I'm already planning to put 5/8" thick drywall once we get there, but figuring out what else I can do. We putty'd the back of the outlets in the shared walls, and made sure the doors are real tight so there won't be a fit issue there.

Brain Genius or Setting Myself Up for Catastrophic Mold with MLV?

I was thinking to put mass-loaded vinyl on both sides of the walls, but since the bathroom obviously generates a lot of steam and moisture, I am worried that small failures will trap a lot of moisture in the internal walls and lead to mold and structural damage. Now neither of the walls to the bathroom are structural but I am so afraid of mold damage. When I rebuild the shower, I plan to make it curbless and waterproof the shit out of its enclosure, but I imagine there will still be some amount of moisture leakage outwards especially since I probably won't do tile to the ceiling.

Which Leads me to a Brain-Genius Solution

Why not load the area between the studs with a lot of drywall? I can further isolate my uncle's room with hangers or other gaps so there isn't a rigid member (the studs) directly behind the drywall. Now space in the bathroom-facing wall in the kitchen is very precious. Losing 1-2" inches to isolate it would mean I can't use off-the-shelf cabinets and makes building it nice sort of impossible for what I can afford. I am categorizing the worst bathroom noises to be "aerial" noises and not structural noises since footsteps do not bother us too much. I wonder if I can contain them well by mass-loading the walls with extra dry-wall offcuts and things. It will be very easy to reinforce the joists this walls rest on from the basement so I don't see any drawbacks but I don't know how super effective this strategy would be.

Any advice is good! Like I said, my main concern is the effectiveness of bootleg mass-loading and avoiding a moisture trap. Also if it is relevant the building is brick with 2x4 studs on the external walls faced by plaster (in the old sections) and drywall in the new sections. Uncle's bedroom, the bathroom, and the kitchen are all along the same external wall. The plumbing wall for the kitchen and the bathroom is the same one.

Thanks!

As you can see it used to have some plastic covering. The frame is held together with (sorta brittle) plastic pins but my main focus is how I'd re-cover the frame in plastic:

• What sort of adhesives should I consider for outdoor metal-plastic bonding?

• Is adhesive and soft (clear) plastic even a good idea?

• Have any of you done something similar?

The light came with an alternate mount that screws on to the handlebar but it makes taking the light off more annoying, and obviously removes the ability to freely put the light on different bikes

I was hoping this design was universal but none of the straps I'm seeing online have the screw hole. Well, there is one very similar strap but I'd have to pay 13€ postage on a 5€ item which offends me on a spiritual level

A woman reached out to my coop shop because she is getting rid of her late son’s tools, specifically a 40W glowforge laser. We already have a laser, so I’m passing it on. NYC area, I believe.

Edit: laser is claimed!

Edit: laser was a scam :(

Got some time this week to get on with woodworking, and I've made something I've been planning for months at this time but couldn't get to doing:

So yeah, it's simply a pine wood structure composed of two 100x60cm^2^ boards, one of which is simply lying on the shotgun and rear seats when folded, and the rear board has a cutout for that weird grey shelf of the trunk, and I cut some mortises in it to fit the base I made for it.

Here you can see the mortises and tenons more in detail. I went with this instead of screws because it's cheap and doesn't require additional hardware, it's easy to assemble and disassemble, and I honestly have fun banging mortises with the chisel and mallet

Here you can see it with the foldable high density foam mattress I picked up on AliExpress for like 45€, which is honestly more comfy than expected if you don't mind a hard bed. I'm a super tall guy so the whole thing needed to be 2m long, and I made it 60cm wide, the same as the mattress.

The support structure for the bottom conveniently disassembles into three pieces and takes very little space in the trunk!

Finally, the whole thing disassembled and in the trunk. I'm quite stoked of how it turned out. The total cost hovers around the 80-90€, I spent essentially 45€ on the mattress (whose plastic cover will obviously be removed once I start using it) and around 40€ on the wood you're seeing (I locally bought for 85€ a 22mm thick pine board of 240x120cm^2^ and used about half of it). There's really not much more to it, since I used no hardware, and I banged it all using handtools on the roman workbench I featured in my previous DIY post.

Oh btw the car is a Renault Grand Scenic from 2006, an old diesel beater I bought for 2000€ with 200.000km some months ago with this idea of travelling around Spain with it. It's pretty long so it's nice for a tall guy like me to be able to lie down fully inside it, and also it's quite fuel efficient, running at around 4.6L/100km in my experience over the past months.

Thanks for taking a look :)

I'm considering a shed but that's a lot of space and money. I'm wondering if there are some cheaper alternatives like maybe fitting a bike rack (??) with powdered concrete. Any thoughts?

The wardrobe was massive and a god damn awful pain in the arse to unbuild (and too big to take to the tip in our tiny car) but it had to be done, leaving this gross wallpaper and possibly damage all the way to the original plaster from ca. 1907.

The shelving tracks on the right are ancient and the screws just wont budge at all. There's half a dozen layers of paint and wallpaper making it worse (you can see how deep it goes where the shelves have been in place even longer). Any ideas on decimating some old ass screws would be cool. We can afford to hire or borrow powertools if that's necessary.

EDIT oh we peeled some of it back and the plaster is fucked to the brick lmao

I've been wanting to get going with woodworking on my newly made low roman workbench for a while now but I couldn't due to thesis manuscript.

Here you can see some rough planing of the surface of another workbench I wanna make for a buddy of mine, I'm gonna make a wooden bow workshop over the summer with friends and they need work surfaces to be able to do so. Thankfully I found a very cheap supplier of lumber in the province of Cuenca and the entire workbench will set me back only some 10€, kinda crazy.

This picture is just mood tbh. I love the little corner I have for my woodworking, the low workbench working both as seating and as workbench simultaneously makes it super compact, and the light was beautiful, finally it's the sunny season in Spain after a few months of unusually rainy spring

Here is the try square I wanted to make, finished and coated in linseed oil. I made some paste wax following the recipe of Wood by Wright (2 parts beeswax, 2 parts linseed oil, 1 part mineral spirits). This try square will open up a lot of possibilities regarding stock dimensioning and precise planning and lineup drawing, I'm stoked about it and it turned very straight!

Finally, a pic of the piece of log from which I split the wood to make the try square, it's from a tree they cut down locally and I hauled it home by hand, so yeah, free wood!! It's super hard, no idea what species it is, I'm used to pine and fir, so working with a hardwood like this is surprisingly different

A while back, my u-lock's plastic mount broke while I was riding my bike, sending the lock straight into the pavement. The impact broke off the hard plastic/rubber bit on the lock itself that slots into the mount so I can't even get a cheap replacement mount from China.

For over a year I've hooked the lock onto one of the shoulder straps on my backpack but I noticed the added weight and stress of a heavy piece of metal dangling off the strap has caused the stitching to start to rip.

I'm getting tired of lugging this thing around. Doea anyone have any ideas for mounting it back on the frame?

My Instagram, in case you're into this sort of thing (Lego).

I finally got around to making my own book. Its for my wife to introduce her to ML.

It looks really ~~janky~~ rustic and I hope it holds together well but we'll see I guess. Unfortunately I was careless with the glue in when sticking the text block to the cover and so it looks really dirty.

I typeset it myself in LaTeX then printed it on regular A4 copy paper, which unfortunately has the wrong grain direction since I want to fold it but finding proper paper is impossible. I'm going to buy a huge roll of paper and cut it myself next time probably since its rather cheap actually, like 20€ for a roll of 0.61x50m A1 paper.

Bound it with the cheapest linen thread, waxed with paraffin because I still dont know of a good beeswax alternative, glued the spine with regular white craft glue. The tapes are really thin linen gauze. I got the boards from the back of notebooks and glued it all together with corn starch. I think this whole book of 300 pages = 75 sheets cost less than a euro since its basically paper, toner, some thread, some gauze and a few grams of corn starch. Oh and the wrapping is some brown packing paper.

I'm hoping to make a couple books like this so I get a library going but I dont know if I'll bind it on board again or just glue it on some carton. It's a lot more effort to glue it on board and they're still warped despite all my efforts.

I'm thinking of printing the covers on 120gsm cardboard and gluing them together over the spine basically thread the linen gauze through the back cover and glue it on, then glue the front cover so the tapes are sealed. then I could just tip the textblock on the covers and it would cause that much warp. Dunno yet though. First I gotta typeset "Imperialsm, the highest stage of capitalism", which is next on the list.

Dear friends,

Last month, I posted this big project idea of mine to Hexbear's as well as Beehaw's DIY communities. Now I'd like to give you an update.

All figures I'm referring to are here: https://imgur.com/a/b8vGfQf

First, a big thank you to all who have replied, you've helped me a lot in making this project a reality. I have distilled your answers, tips and critiques into a text document, and I can happily tell you that they gave me a more realistic understanding of what I want to accomplish.

I formatted the post like this because it's quite long, and I like to yap, as the kids say.

151x39 cm: (length of desk + length of Kallax tower) x (width of Kallax)
A second 151x39 for the other side
280x39 cm: (length of Kallax-es on either side + distance between them)

Open questions at the end of all this:

I'd like to hear your general thoughts and concerns!
Which wood for the long 5m shelf? 
Lap joints as described above: yay or nay?
Lighting systems?
Back wall of desks?

THANK YOU <3

Warning: Long treatise about current hyperfixation-turned career plan

After a lot of research into different hydrolysis devices and the principles they operate on, I feel confident that I've satisfied the theoretical part of this step in my plan: I have the plans for an oxy/hydro fuel cell that I really do think will surpass the designs that inspired it in efficiency and safety. Now I just have to do the blood-sweat-grease alchemy to make it real.

My initial idea for a bulky "double decker sandwich" design, where the anode and cathode plates are two different stacks separated by plexiglass, has been abandoned. Rather than keeping the two gasses separate in this way, which would lead to unavoidable efficiency loss, I'm intermingling the stacks for maximum efficiency while cordoning off one gas-producing surface at a time with 3d printed separators which will be included in the sandwich. Instead of separating the groups of plates, I'm separating the individual spaces between the plates. I am essentially building a scaled up version of this: https://youtu.be/klJzWPo-ZZE?

The separators work by taking advantage of the different polarities in the powered cell: basically, the different sides of the 7 plates will together form a little self-contained mirror hall of positively and negatively charged metal. The negative sides always produce hydrogen, and the positive sides always produce oxygen. But in a normal cell like this, these gases are produced together and rise together, forming the explosive HHO which is very cool but mostly useless for my purposes. But with the addition of the separators, we can split the whole unit into alternating negative and positive layers, which share an input (coolant) but split the outputs. We can channel the gases from these layers alternately into twin manifolds, then into their own tanks and eventually, down two hoses and into a hissing sapphire furnace.

The biggest change I personally have made to distinguish this from other cells like it is the planned addition of heavy nickel plating., The second biggest change was including primitive blowoff valves on each bubbler tank, but I really hope for the nickel plating to be a game-changer, and here's why:

It might mitigate or solve the toxic waste problem while seriously boosting the device's power. I may or may not have gotten into this already, but stainless steel, the best balance between conductive and affordable most hydrocell builders can find, is alloyed with up to 10% chromium. This is fine for building stuff, I think, but if you submerge that metal in caustic liquid and zap it with electricity, some of that chromium will leech out into the fuel, making it not just highly caustic but carcinogenic as well. To avoid this, I'm planning to electroplate a THICK coat of nickel on the plates, so thick that apparently they call what I want to do electroforming. If I can add at least a half millimeter of pure nickel to each plate, I'll be a happy fish. The idea is that the electricity will go along the path of least resistance (nickel is several times more conductive than steel) and spare the vulnerable alloy beneath. This would also greatly increase the cell's power efficiency, because

nickel is several times more conductive than steel

The way I proceed with this now depends on my ability to electroform, and the outcome of my best attempt. If there's some reason it can't work, let me know, I can handle the sadness.

Looking ahead to the next step, I finally found footage of a personal corundum furnace actually working, and seeing it's design has refilled the wind in my sails and eased my doubts.https://youtu.be/YiS3ZUuCH3c (skip to 7:20 for the money shot) It's so fucking simple, the combustion chamber is two modified firebricks. The body is a glorified welding torch with a can of oxides on top, and there are a total two pieces of beginner-level robotics in there. Before this, I wondered blindly and anxiously about how I would design the thing. Now, I see that the current step of constructing the gas cell will absolutely be the most expensive and time consuming part. I'm nearing the peak of the mountain, after which momentum will begin to carry me as a friend. Also, I've been keeping the cost of fittings down by taking them all from Ken Langone.

Still, I do have one or two important questions that my comrades here, who are more versed in things like math and numbers, could maybe fill me in on:

1. How do I calculate the gas output of this thing? The amperage I can do, but the output I cannot. I want a cell powerful enough to potenially fuel two Verneuil furnaces at once down the road.

2. I'll edit this in when I remember it 5 minutes after posting

Hello,

Beginner here. With writing this, I'm increasingly thinking I should hire a carpenter, lol. But I've been wanting to post this for months, so here it goes.

What do I want to build?

I want to build a desk/TV sideboard/shelf combo, that takes up the entire length of a 5-meter-long wall in my living room (see image).

• There's the 'lower part': 60cm deep, 75cm high; two desks on either extremities (i.e. in the corners of the room), flanked by drawers and storage options for all matter of things. The centrepiece is the TV-sideboard, with cupboards for storage and an open solution for A/V devices.
• Then there's the 'upper part': 40cm deep, 200cm high; this is like a shelf that sits on top of the 'lower part', but it is narrower by 20cm. This will be storage for books, records, work stuff, etc... I am not planning on having a back wall on the shelf.

What are the circumstances?

I live in a relatively small apartment (~ 40m²) with my partner. The apartment is a pre-WW1 house, with a room height of 3,2m. The 5m wall is brick, and behind it starts the next house, so it's plenty thick. The living room itself is about 19m².

My questions to the community

My main question is basically how?

• Is it smarter to build the 'lower part' all in one first, then build the 'upper part' on top? Or is it better to build everything around the two L-shaped studs, that separate the desks from the TV? I imagine that the first option is easier to build, whereas the second option provides more stability.
• What tools, screws, wall plugs and techniques would you use to build this? More specifically: how do I anchor things to the wall?
• The material should be wood – but which one would be appropriate?
• I have a couple of other questions, but I'll leave it at that for now...

Thank you so much for replying and taking an interest.

Not for any real purpose yet but I think it would be a fun project and could help us get used to using secure communications outside of our phones. Does anyone have experience setting one up? Also there was a guide posted somewhere on Lemmy recently that I am having trouble finding if anyone could share.
