For example, a DSLR sensor is not all that different than most other camera sensors. The main difference is what is being done on the sensor versus what is broken out for external access.

I’m certainly no expert here, but I tried building an astro photo setup old school style with some old we cams. None of the sensors I had available broke out the features I needed. I could have done some external image stacking but there were a lot of errors in the compressed output from the module. I basically learned I need to buy a sensor based on the features available in the Linux kernel driver to do what I wanted to do, and that randomly chosen cheap webcams didn’t have very much low level access.

From the hardware side, it is a ton of data output that can be challenging to handle and process quickly enough. The frequencies are quite high and that makes circuit design challenging too. It is easier to drop stuff from the stream earlier and output a much smaller final product like image. At least, that was my experience as a maker that was mostly playing in a space that is over my head in such a project.

Makes sense. We are all basically nose blind to our own stink. Change the chem and blind the blinder.

One of the hard realities of my physical disability comes from still cycling. The chronic stress from pain shifted my scent significantly. When I change drop bar tape OMG it is terrible. It was even super corrosive over the first few years. Basically drop bar tape on a bike evaporates a ton of sweat and concentrates the salts and the worst part of your own scent.

For the longest time I thought the scent was only due to diet, but have since learned it is far more complicated, as even with a perfect diet I am still toxic AF. I attribute it to the never ending stress from high levels of constant pain.

So… if it suddenly seems more pleasant, maybe it is not just the HRT. Being in a better place physically and mentally has a substantial impact on scent and health overall. Just be the best you.

As a kid, who doesn’t get a little warped by Samus Aran being female? Maybe it was just my experience growing up in the christocultist world, but I was in denial about Samus at ~7-8 years old with my only familiarity being passive and Smash Bros.

I thought about doing it like this for a long time but never tried it because I think it has several issues. The horizontal layer deposition lines are aesthetically ugly IMO.

Then there is the issue of how you are going to create compliance. If you are going to rely on some super soft filament, I think it kinda defeats the point. Replacement pads are much cheaper than buying some specialty filament.

By printing and bending a tube, it becomes possible to design for both bending into a loop and for the properties of a soft pad.

Lastly, the majority of pads require a sleeve like retention ring that barely slips into a groove around the plastic enclosure body of each side of the headphones. There is a open pocket sewn into the back side of each headphone pad that is a stretchy layer of vinyl used to slip into the groove. It is possible to replace the plate that is used to form this slip ring retainer groove, but then you’ll have exposed screws.

I’m not looking to replace any parts of the headphones, so I need a way to retain the pad using this existing groove. In the pic for the post, one of the test prints is oriented to show the way I incorporated the retaining groove into the design.

Of course, not all headphones are designed like this with the same pads. However, these style pads are used on most low and mid tier headphones because they are all contract manufactured in the same place with only minor variations and where these semi universal type pads are a major cost cutting factor. So designing for this type of pad is designing for the most common style of headphones. One might argue that these are the cheapest pads to replace, and they are. But, knowledge about how modern contract manufacturing works is rather rare, and no one is advertising that their products are the same as everyone else with just a different sticker and color applied or a single variation of molding dies added to create a slight variation in appearance. These pads can be found for $10-$15, but you have to know they are universal and be willing to gamble a bit by buying from whatever middleman has too much stock of these or dies not see them as a profitable thing to market at a markup.

If I wasn’t such a hardcore cyclist, things would be much harder to detect how they impact me in ways I can determine. Basically everything I have taken for depression and pain (from a major chronic spinal injury) only impact my psychology and reduce how much I care about issues. They do nothing to address the core problems. I have a lot more control over my metabolism based on endurance activity. I also have several techniques I use to measure my cognition like a few games that I keep track of for average puzzle completion times. I was on Adderall long before I was disabled. It is the only thing that is a net positive and helps me focus past tremendous pain and stay curious even after a decade of social isolation. I have felt better after getting off of every long term pain and psych med. For psych it was rather limited and just this past year being the 10 year of disability, turning 40, and my primary caregiver going though some troubles that left me existential. I didn’t even see a proper psych for that one. I just told my primary doc and got some Bupropion for a couple of months. I feel a drunk like haze with pretty much all downers. I’m really susceptible to downers in general. Like the few times I smoked cannabis I’m figuratively paralyzed for the rest of the day and can feel the lingering effects for weeks. I’m ADD not ADHD.

But yeah, I pretty much always feel better with no meds versus meds. I also always treat with exercise first, but my situation is weird and depression is totally circumstantially motivated for me.

I felt that way about many cars. They can be a part of your life and define you in odd ways. There are other cool versions of you out there when you are ready though. Don’t be scared to go find them.

I’m weird I guess, in that I have never really owned a normal car. Everything I got was cool and everything I owned I sold for more money than what I paid. Like my 71’ FJ40 over doubled its value over the years that I owned it. My last Camaro was like a totally different car with a different interior, motor, rear end, suspension, and supercharger. I started riding a bicycle everywhere to justify building that one for higher compression than pump gas supports and running a water injection setup on a street car. I was a real car nut that learned to paint cars and owned a body shop just because that is the one aspect of car culture that the fewest people are capable of doing.

Once upon a time I fell on hard times in a recession and had to leave said Camaro with a friend and move back across the country for awhile. It had a cracked block and I had no way to fix that on the fly. I got a job at a machine shop, built a new motor, got a $400 Fiero, fixed it, replaced the passenger seat with my motor and drove 2k miles to toss the motor in the Camaro without a cherry picker or anything but basic tools. I sold the Fiero and then drove the Camaro back 2k miles across the country while troubleshooting and tuning a fresh motor in a beast of a hotrod. That was an epic journey. I even had a ridiculous clutch issue where a stupidly designed plastic ring broke and wiped the disk in the middle of a native American reservation in New Mexico and I had to wait a week to get shipped a replacement, then pulled a trans on the side of the freeway and tossed in the clutch.

Cars that can be owned will be worth a lot more in the future based on the present trajectory of the world. Even if we start swapping engines for motors and batteries that is more valuable than anything new. New cars running proprietary software that is connected to the manufacturer cannot be owned completely and are not reparable. New cars are worthless long term and are already destroying the independent used car market. We still haven’t seen this end game but it is only a matter of time before cars become the new HP inkjet printers. It is already a situation where only the manufacturer’s dealer can service the car so when that stops, so does the car. There is no longer a possibility to buy something cheap or repairing it yourself. I can repair anything including reverse engineering electrical hardware, but not the entire software stack.

In that sense, keeping anything you can actually own is an investment in yourself and your future. Citizens in a democracy are never asked to trust others and sign away their autonomy. Not owning tools and property while trusting others is feudalism. In the present way the world is changing, your old car has far more value than you may realize right now.

The problem is that the infill layers are not well fused and the lack of alignment means they will only cross at angles. This post design can be made solid and turned into cubic with no anchor. That might work with a softer material, but there are still overhangs and the infill pattern is likely to create non linear twist to the bending. At least on my headphones, the tightest part of the bend needs to obfuscate around 60% of the vertical distance on the other side. In other (poor) words, for ever 10mm of vertical height, 6mm is folded out of the way. That is a lot of bulk to push out of the way. Even in this instance I posted, the back side has sections with thinner walls in some areas to make the flex work in such a tight bend without buckling.

Can it be self hosted on a local network safely. I have no chops in internet stuff or servers beyond spinning up Mainsail/Klipper, a basic OpenWRT router, and Gradio mods to Oobabooga Textgen. I have a PC I want to use for network attached storage and a basic LLM, so if Photon can run like that, it would be a good time for me to try it. I’m just not in a position to pay for internet services like a domain and all that. It is also intimidating when I’ve got no one to really help me learn IRL and have never found the ideal entry point I can wrap my head around. That’s why I just whitelist. At least I can’t write a script wrong and nmap the internet or some sketchy download can’t dial out.

I would love to mod the code of a front end to make down votes a toggled option where I only use them for modded communities.

Unless you’ve got a way to mathematically generate the change in infill, don’t bother. Lining up infill patterns and logarithmic strategies are hard. The solid parts are just as important as the flex. Keeping things straight is a challenge.

This is a major curiosity of mine too. Just the shell seems to be pushing the amount of flexibility of this material in my present design. I’m not using any infill. I can alter the shape a lot. I have a cheap pair of thermal cycling bib shorts that were way too small and I never sent back. Those may become a covered print experiment. That material is thick, dense, and still conforms a lot.

I’m most interested in exploring wave shaping. It would be trivial to add more complex shaping in the center cavity. I can imagine making a print support that sits inside the tube and enables me to create some more complex voids in places.

My main goal right now is to com up with an integrated clip that allows one end to open and close easily while looking pretty. Then I can move on to more audio quality tuning.

I haven’t tried a lot of flex materials. I’ve only used them for things like a few seals. Compliant mechanisms have been a curiosity of mine for a long time, but I haven’t had the intuition to establish an entry point project worth trying on my own.

Like as a totally random aside, if this TPU is super dry like how the one test print that looks super crisp with sharp edges, it appears to be air tight. I see a lot of potential for building cheap pneumatic, cable, or passive force driven actuators while playing around with my thumbs sealing each end.

I intuit that this level of usefulness in mechanisms would be hampered by the low quality of the first bridging layers. Absolutely any moisture in the TPU causes random gaps to form as the steam escapes at the nozzle tip in small bursts. Any larger bridging is going to have some amount of dropped passes as a result. I don’t think this is a real issue if the TPU is very dry on a totally enclosed dry feed path to the extruder, but I don’t like the properties of this material when it is super dry. Overall, my design method in this case is likely oriented in the best way for the properties of TPU and the mechanical best case for compliant design. The layer deposition steps and top/bottom layer properties of FDM are not optimal for compliance in most cases. This particular design is capable of compliance both for the bending form to create the headphones pad, and as a pad against the ear after it is installed.

It is also ~$10-$15 for replacement headphone pads, so making and sharing such a design should be limited to materials most people already have on hand. I’m very tempted to try this with a 98A TPE, but it is just too expensive of a material to justify for this project when I’ve had 3 rolls of TPU banging around for years unused and only got them because they were dirt cheap clearance sale materials. I would do a lot more if I had an IDEX, but I don’t need that rabbit hole money bonfire.

If anything, a dirt cheap foaming TPU could be interesting if such a thing existed. It might be possible to create something functionally similar if TPU could somehow be exposed to a humidity controlled environment at a specific percentage, but I have no idea how moisture saturation works on a deep level, like if the saturation would remain regulated by the humidity percentage or if the exposure would allow the filament to always wick all available moisture where a much more complicated setup would be required to ensure consistent properties. Anyways, my point here is that the best properties for me are not from the super dried TPU needed for bridging and bridging is itself a poor mechanism with FDM. It is best if it can be avoided at the design level like I have done here.

The vinyl of all headphones is plastic. I’m not concerned at all. The fear of plastic is mostly paranoia. The vast majority of micro plastics are from car tires yet that is not what people freak out about.

I painted cars for a long time and worked in heavy industry for awhile. I’ve been exposed to truly nasty stuff. Other than my horns, and third arm, I’m mostly fine so long as a full moon doesn’t happen on a Thursday.

Plastics like this are generally stable. TPU is used in the interior of your car and the grips on power tools. There may be some in your sports clothing. You are likely eating food that is packaged in PLA and PET. There is ABS is everything. These are all around you and come in printable forms. The colors made in the modern world are not arsenic, mercury, chromium, and lead based, like was common 200 years ago.

Mostly, the design is motivated by the aesthetics, but also TPU sucks at bridging and supports.

Testing the loudness really needs two sides and a later stage prototype. It is also very subjective without a repeatable testing technique. I personally loath the subjective nature of opinions people have about anything audio related and avoid saying anything about such myself to the best of my ability.

The overlapping joint insert was just a first idea for a design. There is a section at the top of this joint that I didn’t bother to optimise for vase mode but the rest of the print is possible. It would take some tuning to get vase mode fully dialed. I would probably need to use some helix trickery to get the exact stiffness where I need it. Vase mode was and is still likely in the cards.

I also have a design in CAD that I made today. It has an exposed infill pattern and solid shell in places. I used the pictured design to conceptualize how the infill would behave and how much movement to expect. I may never print that one. I still don’t have a way to connect it that I like.

I’m also playing with the idea of covering a print in textile materials and or altering pockets and chambers.

You don’t find many printed headphone pads and the ones that do exist are very ugly IMO. Prototyping in yellow is only just that. I have other colors of TPU on hand.

Overall, this has the potential to dial in many properties from fit to audio properties. The orientation is ideal for the properties of TPU. The abstract concept is broadly universal where this will technically work for the majority of headphones. As is, it doesn’t look terrible in person and I can make this much prettier if I choose.

The pictured setup is an early alpha phase prototype and it is not glued while it is close to the right size so just the friction is holding it together in the pic. I could glue this and it would likely work fine.

Who else has the Alexandrite front end working? It is the only one I have found that just works and doesn’t show down votes. I’d rather have the option to ignore them entirely. The Photon front end doesn’t work for me, likely due to JS or some other aspect that is not straightforward in a white list firewall. I don’t use any apps for anything that can be done in a browser. I have tried a couple of other front ends and have accounts on some other instances, but something about this setup on a-dot-world is the only doom scroll I actually enjoy. The way block fails to actually block and delete doesn’t delete are both major factors pushing me away from Lemmy too after what seems to be a major uptick in negativity here lately.
