how do you find/buy sex stuff? I'm sure there are websites, but I don't even know where to start. What would be safe and reputable? Do you have any suggestions, or advice on picking something "good"? Also thank you for opening your asks for stuff like this.

okay, so here's the shake:

I personally believe that you can buy decent sex toys anywhere, providing that:

The listing is honest about the product's materials

You know what to look for

Silicone, glass, and metal are the safest materials you can use. They're the least reactive with natural bodily chemicals and are the least likely to give you problems.

SILICONE: Not 'silicon'- silicon is NOT SILICONE. Slicone solids are never 100% transparent and might, MIGHT appear translucent and foggy at the clearest. Silicon might be shiny OR matte, but if it's matte please know that velvet or soft-touch coatings are most often non-silicone materials added after the toy itself is molded. This is usually fine, but if you know your body is sensitive to that, one brand I know has the texture built into the mold is Fun Factory. It's pricy, but it's high quality and comes with a warranty.

NEVER ASSUME AN ITEM IS SILICONE UNLESS THE ITEM IS DESCRIBED AS SILICONE.

GLASS: Tempered glass is usually fine. If you notice chips, cracks, or hairline fractures in it, bag it up and throw it out.

Metal: Same story. Chipping, flaking, cracks, oxidization, toss it. Acrylic toys with metallic coatings will degrade in contact with oils, unlike actual metal, so be sure to check materials.

People shit on sites like Adam & Eve and Pinkcherry, and yeah those are cheap stores that dont sell the best stuff, but they still have LOADS of good quality product and do frequent sales and clearouts if you're nervous and not looking to drop a lot of cash right off.

If you can afford it, brands I absolutely recommend are Womanizer, Fun Factory, Hitachi (now owned by Vibratex), Tom of Finland, Sinvention, and We Vibe. They're all high-quality and most have warranties for damage or malfunction.

On the cheaper end, Calexotics, Doc Johnson, Evolved, and Ouch!.

Websites like Bad Dragon, Extreme Restraints, and Sinvention are known to have good customer service and high-quality products.

Websites like Adam and Eve, Pinkcherry, and Lovehoney I've heard good reviews for, you just need to be careful about what you buy.

I've yet to encounter a legit site that isn't discrete, btw. Everything is usually sent out in boxes.

Please avoid AliExpress. You CAN buy there, but I don't trust that shit

fantasy dildo recs please? im trying to find one that isnt like $100 but is still good and reputable and wont fill my body with microplastics. ive been looking at neotori and they look great but;; the price;;; anyway yeah recs please?

hi! i have a lot of information for you.

first off, my specific recommendations of fantasy toy shops i’ve bought from or know to be reputable: uberrime, wandering bard, twilight meadow creations, strange bedfellas, pleasure forge, pp sculptors, batbites, xenocat artifacts. all of these shops have toys under 100 usd. uberrime especially has a huge selection including non-fantasy, realistic, and dual density. my top 3 fantasy toys right now are TMC’s ambrose (mini), wandering bard’s shadow demon (x small), and uberrime’s ardor dragon (small). highly recommend ambrose to transmascs with bottom growth. also it looks cool as fuck. mine is bright green and yellow.

second, this google doc is a masterpost of fantasy and fantasy-adjacent sex toy companies (created as a list of alternatives to bad dragon) and is organized quite well, and includes some shops to be wary of. it was last updated in 2022 so it’s outdated, but it’s massive and still quite useful. safe fantasy toys dot com also lists body safe toy companies, although you should still check reputability of the company before you buy (some of the companies listed on the site should still be avoided for various reasons— try cross checking with the google doc, browsing reddit, etc). all of the specific companies i recommend in this post use platinum silicone only, but if you go searching for other toys make sure to avoid jelly and other porous materials because they cannot be sanitized properly and will store bacteria. just like with piercing and body jewelry (another one of my special interests lol), it’s always better to pay more for safety when it’s something going inside your body. reputable stores will always list the material, and tend to have pages on their sites with even more specific information on their silicone. shipping also affects the price, especially international shipping.

also, when youre shopping for fantasy toys, make sure you check the sizing. smaller toys are frequently under 100 usd. many fantasy toys tend to be quite large anyways, especially knotted toys (many small knotted toys still have diameters of 2”+ which is too large for me personally. for reference i think the average human penis is somewhere around 1.5” diameter and my personal maximum for toys right now is ~1.75). there’s so much diversity in fantasy toys that you will probably be able to find toys that fit your desired length/girth and are still classified as small and therefore less expensive. if you’re new to fantasy toys or have trouble with insertion (or even just have an average sized vagina/rectum), small fantasy toys can be cost efficient and accessible and more fun than more standard toys. many stores will also sell b-grade toys at a discount for minor cosmetic flaws that don’t affect usage. also, there’s a pretty big market for secondhand toys/dong sales on twitter, reddit, etc so if you’re willing to buy secondhand, that can be more cost efficient. quality silicone toys can be properly sanitized by boiling and other methods. for more cheap options— good glass toys can frequently be under 50 usd, and are easy to sanitize. also, tantus isn’t quite a fantasy brand, but it’s very high quality and has some great toys on the cheaper side (i love the tantus magma). and if you want a really good cheap vibrator, the romp hype is amazing and only 35 usd.

i am by no means an expert, just incredibly autistic, but i hope this helps! i’m always happy to try answering questions about sex toys!

how would the housewardens react to walking in on you pleasuring yourself??

Riddle walks in, hardly spares you a glance for more than a second, before he's swiftly turning on his heel and slamming the door shut behind him. He immediately apologizes for intruding without knocking and his face is the brightest shade of red. He doesn't know what else to say, so he awkwardly leaves it at that. But you're all he can think about for the rest of the day.

Leona leans against the door frame so casually, his features alight with cocky pride. He won't say anything, merely admiring the pretty view, but when you notice him he'll smirk at you and tell you to keep going. Don't let him stop you. Unless you'd prefer if he helps you. :) if that's the case, he might as well show you how it's done. Since you let him use your lap as a pillow before, he supposes he can let you ride him. After all, the real thing is so much better than cheap silicone.

Azul opens the door, sees you, and promptly shuts it. He has to mentally reset himself after seeing a sight he has only witnessed in delusions and dreams. He can't look foolish. He has to be casual about this. He has to look suave. He opens the door again and there's the faintest hint of blush on his face and his voice is higher than it normally is, but he tries so hard to be smooth when he asks if you need a hand. Or two. Or three. He has ten at his disposal. Azul doesn't think you'll agree to this, let alone sign a contract, but he still tries because it can't hurt to do so when he's caught you in a vulnerable state. And depending on your answer, you might just surprise him.

Kalim thinks you look so cute when your face is twisted in pleasure, and he'll verbalize every praise that comes to his mind. You shouldn't be so embarrassed. There's nothing wrong with pleasuring yourself! And he wants to join you! Let him have some fun with you; he promises it'll feel good if it's with him. After all, it's so lonely doing things solo. Kalim is also the type to see what toys you use, if any, and will offer to buy you the best of the best. You shouldn't have to use cheap toys that are prone to breaking. Let him spoil you with the best, most high-quality products. <3 it's what you deserve!

Vil is pleasantly surprised. Of course he knew you were beautiful both inside and outside, but there's a certain level of intimate beauty in viewing you from the doorway while you're so wrapped up in ecstasy, oblivious to his arrival. As tempting as you look, it's unbecoming to leer and Vil is always one for mannerly conduct. He will shut the door and be on his way if you haven't noticed him, but if you do he will apologize for interrupting and offer to leave without another word. But if you ask him to stay, how can he possibly say no?

Idia never leaves his room, so he's probably watching you through the secret cameras scattered throughout Ramshackle Dorm. Or perhaps you're aware of their existence and want to give him a little show. :) in any case, it has Idia choking on his energy drink because this is a first. He's only ever observed you studying in the lounge or sleeping in your bed or playing games with your friends or marathoning movies. So this is a new sight and he definitely isn't complaining. He'll record the entire thing for his own enjoyment and for later reference when he needs new material to masturbate to.

Malleus often visits without warning, so it really shouldn't be so surprising to see him in the window. Although this is the first time he's happened upon you while you were busy with your own private affairs. Malleus doesn't find it embarrassing; rather, he thinks you look so very darling on your bed, practically glowing in the moonlight. There's nothing to fret over; nudity isn't something you should be so flustered by. After all, he thinks you look so perfect with and without clothes on. Malleus is so unintentionally smooth and genuine in his approach. He'll leave if you really wish it, but he has no problem staying to keep you company in more ways than one so long as you're okay with it.

New strategy enhances 2D transistor dielectric layers

Transistors based on two-dimensional (2D) semiconductors, such as molybdenum disulfide (MoS2) and tungsten diselenide (WSe2), could outperform conventional silicon-based transistors, while also being easier to reduce in size. To perform well, these transistors need to be based on high-quality dielectric materials, which can be difficult to prepare. Researchers at Nanyang Technological University, Nanjing University of Aeronautics and Astronautics recently introduced a new promising strategy to prepare the dielectric materials for these transistors. Their approach, outlined in a paper published in Nature Electronics, was successfully used to deposit an ultrathin and uniform native oxide of gallium Ga2O3 on the surface of MoS2. "Traditional methods of preparing dielectric layer, such as atomic layer deposition (ALD), encounter quality problems because of the high-quality surface of 2D semiconductors without sufficient nucleation points, especially at thin thicknesses down to a few nanometers," Kongyang Yi, first author of the paper, told Tech Xplore.

MIT engineers grow “high-rise” 3D chips

New Post has been published on https://thedigitalinsider.com/mit-engineers-grow-high-rise-3d-chips/

MIT engineers grow “high-rise” 3D chips

The electronics industry is approaching a limit to the number of transistors that can be packed onto the surface of a computer chip. So, chip manufacturers are looking to build up rather than out.

Instead of squeezing ever-smaller transistors onto a single surface, the industry is aiming to stack multiple surfaces of transistors and semiconducting elements — akin to turning a ranch house into a high-rise. Such multilayered chips could handle exponentially more data and carry out many more complex functions than today’s electronics.

A significant hurdle, however, is the platform on which chips are built. Today, bulky silicon wafers serve as the main scaffold on which high-quality, single-crystalline semiconducting elements are grown. Any stackable chip would have to include thick silicon “flooring” as part of each layer, slowing down any communication between functional semiconducting layers.

Now, MIT engineers have found a way around this hurdle, with a multilayered chip design that doesn’t require any silicon wafer substrates and works at temperatures low enough to preserve the underlying layer’s circuitry.

In a study appearing today in the journal Nature, the team reports using the new method to fabricate a multilayered chip with alternating layers of high-quality semiconducting material grown directly on top of each other.

The method enables engineers to build high-performance transistors and memory and logic elements on any random crystalline surface — not just on the bulky crystal scaffold of silicon wafers. Without these thick silicon substrates, multiple semiconducting layers can be in more direct contact, leading to better and faster communication and computation between layers, the researchers say.

The researchers envision that the method could be used to build AI hardware, in the form of stacked chips for laptops or wearable devices, that would be as fast and powerful as today’s supercomputers and could store huge amounts of data on par with physical data centers.

“This breakthrough opens up enormous potential for the semiconductor industry, allowing chips to be stacked without traditional limitations,” says study author Jeehwan Kim, associate professor of mechanical engineering at MIT. “This could lead to orders-of-magnitude improvements in computing power for applications in AI, logic, and memory.”

The study’s MIT co-authors include first author Ki Seok Kim, Seunghwan Seo, Doyoon Lee, Jung-El Ryu, Jekyung Kim, Jun Min Suh, June-chul Shin, Min-Kyu Song, Jin Feng, and Sangho Lee, along with collaborators from Samsung Advanced Institute of Technology, Sungkyunkwan University in South Korea, and the University of Texas at Dallas.

Seed pockets

In 2023, Kim’s group reported that they developed a method to grow high-quality semiconducting materials on amorphous surfaces, similar to the diverse topography of semiconducting circuitry on finished chips. The material that they grew was a type of 2D material known as transition-metal dichalcogenides, or TMDs, considered a promising successor to silicon for fabricating smaller, high-performance transistors. Such 2D materials can maintain their semiconducting properties even at scales as small as a single atom, whereas silicon’s performance sharply degrades.

In their previous work, the team grew TMDs on silicon wafers with amorphous coatings, as well as over existing TMDs. To encourage atoms to arrange themselves into high-quality single-crystalline form, rather than in random, polycrystalline disorder, Kim and his colleagues first covered a silicon wafer in a very thin film, or “mask” of silicon dioxide, which they patterned with tiny openings, or pockets. They then flowed a gas of atoms over the mask and found that atoms settled into the pockets as “seeds.” The pockets confined the seeds to grow in regular, single-crystalline patterns.

But at the time, the method only worked at around 900 degrees Celsius.

“You have to grow this single-crystalline material below 400 Celsius, otherwise the underlying circuitry is completely cooked and ruined,” Kim says. “So, our homework was, we had to do a similar technique at temperatures lower than 400 Celsius. If we could do that, the impact would be substantial.”

Building up

In their new work, Kim and his colleagues looked to fine-tune their method in order to grow single-crystalline 2D materials at temperatures low enough to preserve any underlying circuitry. They found a surprisingly simple solution in metallurgy — the science and craft of metal production. When metallurgists pour molten metal into a mold, the liquid slowly “nucleates,” or forms grains that grow and merge into a regularly patterned crystal that hardens into solid form. Metallurgists have found that this nucleation occurs most readily at the edges of a mold into which liquid metal is poured.

“It’s known that nucleating at the edges requires less energy — and heat,” Kim says. “So we borrowed this concept from metallurgy to utilize for future AI hardware.”

The team looked to grow single-crystalline TMDs on a silicon wafer that already has been fabricated with transistor circuitry. They first covered the circuitry with a mask of silicon dioxide, just as in their previous work. They then deposited “seeds” of TMD at the edges of each of the mask’s pockets and found that these edge seeds grew into single-crystalline material at temperatures as low as 380 degrees Celsius, compared to seeds that started growing in the center, away from the edges of each pocket, which required higher temperatures to form single-crystalline material.

Going a step further, the researchers used the new method to fabricate a multilayered chip with alternating layers of two different TMDs — molybdenum disulfide, a promising material candidate for fabricating n-type transistors; and tungsten diselenide, a material that has potential for being made into p-type transistors. Both p- and n-type transistors are the electronic building blocks for carrying out any logic operation. The team was able to grow both materials in single-crystalline form, directly on top of each other, without requiring any intermediate silicon wafers. Kim says the method will effectively double the density of a chip’s semiconducting elements, and particularly, metal-oxide semiconductor (CMOS), which is a basic building block of a modern logic circuitry.

“A product realized by our technique is not only a 3D logic chip but also 3D memory and their combinations,” Kim says. “With our growth-based monolithic 3D method, you could grow tens to hundreds of logic and memory layers, right on top of each other, and they would be able to communicate very well.”

“Conventional 3D chips have been fabricated with silicon wafers in-between, by drilling holes through the wafer — a process which limits the number of stacked layers, vertical alignment resolution, and yields,” first author Kiseok Kim adds. “Our growth-based method addresses all of those issues at once.” 

To commercialize their stackable chip design further, Kim has recently spun off a company, FS2 (Future Semiconductor 2D materials).

“We so far show a concept at a small-scale device arrays,” he says. “The next step is scaling up to show professional AI chip operation.”

This research is supported, in part, by Samsung Advanced Institute of Technology and the U.S. Air Force Office of Scientific Research.

Key Design Considerations for Pantograph Support Insulators in High-Speed Rail Systems

In the realm of high-speed rail systems, every component plays a crucial role in ensuring safe and efficient operations.  Among these components, pantograph support insulators stand out as critical elements that facilitate the seamless transmission of power from overhead lines to the train's electrical system.  As a leading pantograph insulator manufacturer in India, Radiant Enterprises recognizes the importance of meticulous design considerations in crafting reliable and durable insulators.  In this blog post, we'll explore the key design considerations essential for pantograph support insulators in 25 KV high-speed rail systems, shedding light on Radiant Enterprises' commitment to excellence in manufacturing.

Understanding Pantograph Support Insulators

Pantograph support insulators are integral components of the overhead electrification system in high-speed rail networks.  These insulators provide electrical isolation and mechanical support for the pantograph, which is the apparatus mounted on the train's roof responsible for collecting electricity from the overhead wires (catenary).  In 25 KV high-speed rail systems, where trains operate at exceptionally high speeds, the performance and reliability of pantograph support insulators are paramount.

Design Considerations for Pantograph Support Insulators

Material Selection:  The choice of materials significantly influences the performance and longevity of pantograph support insulators.  At Radiant Enterprises, we utilize high-quality, durable materials such as silicone rubber or composite polymers that exhibit excellent electrical insulation properties, mechanical strength, and resistance to environmental factors such as UV radiation, pollution, and temperature variations.

2.   Electrical Insulation:  Ensuring reliable electrical insulation is paramount to prevent electrical arcing and ensure the safe transmission of power.  Our pantograph support insulators are engineered to withstand high voltage levels (25 KV) and exhibit low electrical conductivity to minimize power losses and mitigate the risk of electrical faults.

3.   Mechanical Strength:  Pantograph support insulators are subjected to mechanical stresses induced by the pantograph's movement and external forces such as wind loads and vibrations.  Therefore, our insulators undergo rigorous mechanical testing to ensure they can withstand these forces without deformation or failure, ensuring uninterrupted operation and minimal maintenance requirements.

4.   Corrosion Resistance:  In outdoor environments exposed to moisture, pollution, and corrosive agents, corrosion resistance is essential to maintain the structural integrity of pantograph support insulators over their operational lifespan.  Our insulators are engineered with corrosion-resistant materials and undergo surface treatments to enhance their resistance to rust and degradation, ensuring long-term reliability and performance.

5.   Dimensional Accuracy:  Precision engineering is critical to ensure proper fit and alignment of pantograph support insulators with the overhead wires and the train's pantograph.  Our insulators are manufactured with tight tolerances and undergo strict quality control measures to guarantee dimensional accuracy and compatibility with the rail infrastructure, minimizing installation challenges and optimizing performance.

6.   UV Stability:  Exposure to ultraviolet (UV) radiation can degrade insulator materials over time, compromising their electrical and mechanical properties.  Therefore, our pantograph support insulators are formulated with UV-stabilized materials that withstand prolonged exposure to sunlight without degradation, ensuring reliable performance and longevity in outdoor applications.

The Commonly Used Metal 3D Printing Materials

Metal 3D printing uses a variety of metal powders, wires, and even liquid resins infused with metal. Almost any metal can be 3D printed, from stainless steel to nickel-based alloys, and in practice, about 8 are most commonly used. The most common question about metal 3D printing is: Will the final part have the same mechanical properties as a machined, moulded or forged metal part? The answer is yes, and sometimes even better mechanical quality, but it depends a lot on the metal 3D printing technology you use, the type of feedstock used, post-processing and the shape of the part. In addition, the comparison depends on the aspects you are concerned about: for example, tensile strength, static load strength, high cycle fatigue, and so on.

In general, the material properties of metal parts made by metal bond jetting are equivalent to those of metal parts produced by metal injection moulding, and it is one of the most widely used manufacturing methods for the mass production of metal parts. These 8 metal alloys below are just the beginning of what is possible today as metal material producers continue to push the boundaries and customize metal alloys for specific needs using specific metal 3D printing technologies.

1.Stainless Steel Feature: All-round Stainless steel is not the material most commonly used in 3D printing, but many alloy varieties. The first two are 316L and 17-4 PH, but also 304L, 15-5 PH, 420, 254, PH1, GP1, 630, and 410 can be printed, as well as custom blends produced by material manufacturer. These steels are specifically designed to resist corrosion. They are a lightweight and affordable metal that is ideal for 3D printing. This is because it is faster and cheaper than traditional methods and can print small batches and complex parts. 3D printing is the preferred option for companies that need a single tool or several replacement parts. Stainless steel can be used in almost any type of 3D printing, from economical wire for extruded 3D printing on benchtop machines to powder for binder jetting and laser powder bed fusion, and even resin.

2.Tool Steel Feature: High hardness, good wear resistance Tool steels, like stainless steels, come in different varieties with different tensile strengths, ductility, hardness and other properties. Tool steels are a variety of alloy steels designed specifically for the manufacture of tools. They are known for their hardness, wear resistance and ability to hold a cutting edge at high temperatures. This 3D printing steel is commonly used in the manufacture of injection mould inserts, aerospace components, military applications, manufacturing tools, as well as construction and architecture. The main advantage of 3D printed tool steel is not only its strength, but also its unique ability to create parts with internal channels (e.g. cooling channels in moulding tools) and lattice fillings that cannot be manufactured by traditional methods.

3.Low-Alloy Steel All 3D printing steels are alloys, but this category includes steels with low or less than 5 per cent of other elements. These low alloy steels are designed to have higher mechanical properties and greater resistance to wear and corrosion than other steels which are commonly used in automotive, aerospace and structural applications.

4.Aluminum Feature: Lightweight and corrosion resistant For aerospace, automotive and industry, the design freedom and cost efficiency of 3D printing further enhances the lightweight and chemical resistance of aluminum components. The use of aluminum and aluminum alloys in 3D printing is surging because the metal is economical and easy to 3D print. Like most metals, aluminum can be used as wire or powder for a variety of 3D printing techniques. Aluminium has good chemical resistance, is very light and has one of the best strength-to-weight ratios of any metal. Combined with silicon and magnesium, it is the choice of many in the aerospace and automotive industries because of its ability to withstand harsh conditions.

5.Titanium Feature: Lightweight and biocompatible As strong as steel but half the weight, titanium is a complex metal that is practically made for 3D printing. Titanium has become one of the most commonly used metals in additive manufacturing, with a wide range of applications in aerospace, joint replacement and surgical tools, racing car and bicycle frames, electronics and other high-performance products. Titanium and titanium-based alloys offer high mechanical strength, high strength-to-weight ratios and better corrosion resistance than stainless steel. It makes rockets and aircraft lighter, thus saving fuel and increasing payload capacity. In the medical industry, 3D printed titanium implants have been successfully used in the spine, hips, knees and extremities due to the inherent biocompatibility and good mechanical properties of the metal, coupled with the ability to customize porous structures with 3D printing, allowing for osseointegration and mass customization for better patient outcomes.

6.Copper Feature: Electrical and thermal conductivity 3D printing using pure copper and space-age copper alloys is available with a range of metal 3D printers and services. You can create rapid copper prototypes using copper filament on an FDM 3D printer and large copper rocket boosters using copper alloys on a laser powder bed fusion 3D printer. There is also copper wire and copper resin for micro 3D printing. In fact, copper plays a huge role in the global sustainable development goals as a key component of electric motors, charging infrastructure, solar energy and batteries.

7.Nickel Alloy Feature: Extreme environments resistant Nickel-based alloys and "high-temperature alloys" are known for their excellent high-temperature strength, corrosion and oxidation resistance. These alloys retain their strength and mechanical properties at high temperatures. They are commonly used in demanding applications such as aerospace, gas turbines, chemical processing and marine environments. In recent years, these alloys have also become increasingly popular in 3D printing, especially in the aerospace and automotive industries. When referring to nickel alloys, you may hear the term inconel. Inconel is the trade name for a range of nickel-chromium-based high-temperature alloys, including IN625, IN718 and IN939. Nickel alloys are generally more expensive than other materials such as steel and aluminium and may not be suitable for low temperature applications.

8.Cobalt Chrome Feature: High temperature and corrosion resistance 3D printed cobalt chrome has a high strength-to-weight ratio and excellent corrosion resistance, making it a good material choice for aerospace components and industrial machinery. It is also biocompatible and is often used in orthopaedic implants, dental prosthetics and medical devices that require long-term contact with biological tissue. Cobalt-chromium alloys can be processed using additive manufacturing techniques such as selective laser melting (SLM) or electron beam melting (EBM). This allows complex geometries and customized parts to be produced with minimal material waste, making it attractive to industries adopting advanced manufacturing techniques.

To sum up, metal 3D printing uses a wide range of metal powders and wires, including stainless steel, tool steel, etc. to print complex parts with superior mechanical properties. Commonly used metals in 3D printing include aluminum, titanium, copper, nickel alloys, tool steel, cobalt-chromium alloys, stainless steel for aerospace, medical and jewellery applications and more.
