general life series designs for Grian and Joel :3 their wings are clipped bc they cant fly in the life series and ik other ppl draw them tied back or straight up vanished but i feel like this way makes the most sense? like it doesn't directly injure them (although birds with clipped wings are often clumsier and hurt themselves on accident more often) but evens the playing field a bit
sketch in the corner is of joel and his wolves in 3rd life btw
Tumblr media Tumblr media
and the other one was meant to be ren and martyn on skizzle point yk when they're cornered (also in 3rd life)

Is Amy...being hassled by a gardener Hey Ho??
In 2016, this is the first time Classic Amy’s design had appeared since...I’d like to say her evil counterpart Rosy the Rascal? (Not counting one-panel flashbacks in the background of some issues)
For real, Classic Amy is simply adorable in Sonic: Mega Drive. Hesse brings out a kind of adorable charm in her that I’m happy brought more attention to Amy’s old design, to the point she’d reappear in Sonic Mania Adventures and the Sonic Origins cutscenes!

Tails being a snarky little shit is funny too tho

Wi-fi Antanna In Chennai
WiFi antennas in India come in various types and are used to extend the range and improve the signal strength of wireless networks. Here’s an overview of some common WiFi antenna types available in India and their typical uses:
Types of WiFi Antennas
Omnidirectional Antennas
Description: These antennas radiate signals in all directions (360 degrees horizontally).
Use Cases: Ideal for general-purpose WiFi coverage in homes, offices, and small outdoor areas.
Directional Antennas
Description: These antennas focus the signal in a specific direction, providing longer range and better performance in that direction.
Use Cases: Used for point-to-point connections, such as between buildings or for targeted coverage in large open areas.
Yagi Antennas
Description: A type of directional antenna with a high gain, often used for long-distance communications.
Use Cases: Suitable for rural areas where the WiFi source is far from the user, such as connecting to distant WiFi hotspots.
Parabolic Grid Antennas
Description: These antennas have a parabolic shape, providing very high directional gain.
Use Cases: Used for very long-distance point-to-point links, often in combination with outdoor WiFi systems.
Panel Antennas
Description: Flat antennas that can be mounted on walls or poles, offering moderate to high gain.
Use Cases: Ideal for point-to-multipoint setups, covering a specific area with stronger signal.
Popular Brands and Models in India
TP-Link
Models: TP-Link TL-ANT2408C (omnidirectional), TP-Link TL-ANT2415D (directional)
Known for: Reliability and good performance for home and small business use.
Ubiquiti

Buying Considerations
Range and Gain
Higher gain antennas provide better range but may have a narrower coverage area.
Consider the environment (indoor vs. outdoor) and the distance you need to cover.
Compatibility
Ensure the antenna is compatible with your router or access point.
Check for connectors (RP-SMA, N-Type) and ensure they match your equipment.
Usage Environment
Indoor antennas are typically less rugged than outdoor models.
For outdoor use, look for weatherproof and durable designs.
Regulations
Be aware of local regulations regarding the use of high-gain antennas and frequency bands.
Where to Buy
Online Retailers: Amazon India, Flipkart, Snapdeal, etc.
Electronics Stores: Reliance Digital, Croma, Vijay Sales, etc.
Specialized IT Shops: Local computer and networking equipment stores.
Tips for Optimal Use
Position antennas in a central location for omnidirectional coverage.
Elevate antennas to reduce obstructions and improve line-of-sight.
Use quality cables and connectors to minimize signal loss.
By considering these factors, you can choose the right WiFi antenna to improve your network’s performance in India.

Hello, Anon, this is your Oldie Chinese Diaspora Anon™️. I am sorry to keep you waiting. As you’ve probably noticed, vinyl and non-resin dolls are usually not my forte. It took a while to dig up some information for you, but I hope to be able to answer your questions.
The advent of “Cheaper, affordable MJDs” didn’t come from the desire to make BJDs affordable. In fact, the technology that really elevated the production of this kind of MJDs started from what we understand as vinyl collectibles. These small figurines are made from a combination of PVC powders as well as a series of other emulsifiers, lubricators and activators (From the factory that produces them, here: http://www.dgzhonglinhb.com/news_content-859681.html ) Different companies have slightly different recipes, which would explain the different pliability of their final products. The technology was first created as a way to create memorabilia that are of limited edition and they were first considered as collectibles. They’re known internally as “Urbanvinyls” and include signed trinkets that can go for hundreds, if not thousands of dollars. Some examples would be KAWS, Kidrobot, Tokidoki, Bearbrick etc.
With the rise of “Made in China” soft power, the internally patriotic sentiment had fostered local artist-designed vinyl collectibles, which had eventually ballooned into the blind box craze that we see in the last 4-5 years. It also opened a door for vinyl/PVC based MJDs. I do not think they were specifically made to usurp the DD/SmD market, but since “moe sells”, a lot of the new doll companies go with the cute, anime-inspired aesthetic while the blind boxes cater to more design elements. These newly designed MJDs tend to be small, usually 1/12 and 1/6; larger ones exist, but they are rare. In all, they are created to be much more like their direct inspiration, the “blind box collectibles” than what we would usually consider to be articulated dolls. It also meant their target demographic is very different as well. The lower price point allows more people to impulse buy out of FOMO; these are things you buy on a whim instead of saving up to buy.
In this arena, Imómó is not alone in terms of aesthetic, pricing or packaging. Other companies in this group include Hüa Jüan, Tïny Fóx, UFdóll, CNDóll, Kimdóll, Pópmilk, Mónst and the upcoming YünLai/LückyDoll, etc (but not YMY – who has lost a battle with Piccodo for copying their body design recently). These dolls are created with a higher number in circulation in mind – but still limited enough to stimulate the FOMO behaviour – with shared features (sharing bodies, design elements, etc). To keep the production cost down, these dolls would be considered rather threadbare compared to BJDs. I have seen box opening videos where the floating “blind box” heads were packaged in a brown shipping box and wrapped around in clear plastic bags with no other packaging material. The “accessories” for these dolls are usually close to none as well – no or very simple COAs, basic box, air-filled tubes instead of fabric cushions, etc.A snapshot in time in online stores shows that Imómó is definitely not an outlier in the new era of MJDs: https://weibo.com/1448114577/Nj9fqfog3
https://www.dollyteria.com/product-list/58?page=1
If there’s something that really made Imómó stand out, it was the rumours that spread within Chinese doll collectors earlier in the summer of 2023 about the company not issuing legitimate receipts (usually with the intention to cook their books to pay less in taxes). They accuse Imómó of being a “Three Nothings” company (no date of manufacture, no QC and no source factory) with really awful customer service. They had registered the company as an “overseas-based” one so they would be in a different tax bracket. Some collectors also accuse the owner and their family members infiltrating doll collector groups to hype up their own products and downplay the complaints. A popular agent, SWDólls, were also implicated in helping them to not issue traceable receipts. (Details and screen grabs can be found here: https://weibo.com/7303299294/N8lHE6wGE?type=repost ) I have also heard of owners who complain about the parts not fitting well, the seamlines were wide and uneven as well as other imperfections that should’ve never passed QC, if there was a QC.
I understand that most of us, who are looking in from the outside, would wholly welcome a new era of articulated dolls that are affordable. They are a great entry point for people who want to get into BJDs or just want to collect these dolls on their own. I personally think they are great the way they are, because they are starting to populate a brand-new market for people who like dolls in general. However, the first company that most folks encounter in this group was probably Imómó. I cannot comment on the accusations made by the Chinese collectors; all I can say is, I am hoping that the other named companies start to make headway into the overseas market. We’d been waiting.
Note: The write up here didn’t include previously existing vinyl dolls such as Azóne and Obitsü or the vinyl versions of resin dolls such as Kinókó Jüice and Püyüdolls. This write-up only includes MiC, PVC-based, original, MJDs. My understanding is that they are not on par with the company in question in terms of price range, target market and country of origin. I didn’t think they’d make for a fair comparison, but your mileage may vary.

Still need to model the mini-switches this is using so I can pop holes in the case but it is one in the morning. Apple Watch 44mm for scale. You can see the smd pads for the buttons that go on the side, although I might have to redesign, it looks like they might be hard to get in normal quantities.
Tumblr media Tumblr media Tumblr media Tumblr media
Still need to figure out what kind of battery and motor to use, but this is the first time I've played with KiCAD's 3D export. Nice tool, even if it needs some finagling to make it work. Forgot to set my design rules, hence the silly trace widths. This all needs to be redrawn anyway it's just a draft.

Reverse-engineered a serge gain cell that i have a while ago (and then found another person's schematic online, and they matched - good job us). Today i made a layout for it with smd parts. Here it is next to a DIL14 package for reference :3
Tumblr media
I split the 8-pin header into two 4-pin headers, cause the one thing i dislike about ken stone style implementation is it's flimsily fixed to the board: it's one 8-pin header and an almost-square board sticking out perpendicular or laying parallel to the motherboard, IMO both options are unreliable unless you glue them up. So, two headers like this make sure that the board is securely fit to its motherboard.
Also this version has the power header rotated 90 degrees. There's a version where they are both vertical and yes the board looks prettier, but - think about it - serge designs always use a bunch of these, not one. So it makes sense to make it easier to run power through all of the gain cells like a skewer on one side, while breaking out the signal taps on the other side. It is a *slightly* less secure mount than two headers parallel, and definitely less pretty as a board, but i think it's good enough for such a huge improvement in board tracing ease.
VCFQ here i come!... next year probably

Lockprowl ask
I had suggested IDW lockprowl, because I saw an interesting fanart about them
It has been a looong time since I read IDW and I'll be completely honest: I had no recollection of IDW Lockdown and had to look him up to refresh my memory on his design. Do I remember his personality at all? No. Is he still a husky voiced bounty hunter in my heart? Yes
I'm gonna recycle an old concept here, and say that Prowl is actually the one that gets sparked first. Maybe they're actually a couple and this is a schmoopy alternate timeline where all is well and they're happily living together, married and content. Maybe it's like canon and they have a very on again, off again relationship.
Regardless. Prowl is the one who's sparked, and there's immediately worry of the baby growing too big for him to safely birth. This wasn't planned at all, and situations where the carrier's frame is too small can quickly turn lethal. Prowl in a slight panic immediately jumps to termination, but Lockdown suggests an alternative: a transplant. There's no way the bitty's size could be too big for him, and, well. He's not averse to the idea of being a parent with Prowl.
They caught the carrying cycle early so the transfer would be swift and painless. The earlier a baby spark is moved, the better, generally. Prowl consents to the operation, and they get scheduled right away. Thankfully, it all goes extremely well: the newspark anchors to Lockdown with barely a flicker, and his carrying protocols online to begin preparing to begin designing and constructing their sparkling's body.
Prowl is... not quite anxious, about being a sire. Worried, maybe? Weary? Bracing for impact? No, he's more like... apprehensive. Yes, that's the word he'd use to describe himself. He's apprehensive about parenthood. After all, having a baby is practically a full time job. They need a lot of care, around the clock. They're so fragile and so easily impressionable: one seemingly tiny, inconsequential mistake could follow them for the rest of their lives and shape what kind of person they could become. They need constant love and attention smd supervision, and they're both so busy. Perhaps it's pessimistic but he's approaching this with shrewd realism: as it stands now neither of them are ready to properly care for a sparkling. They're making a baby, an entire person. Someone that will someday be a fully fledged adult with a functioning psyche that they are responsible for sculpting. If they mess this up they could make the worst serial killer the world has ever seen, so they need to get their act together and be perfect parents.
He becomes... idk. Is there a word for like a groomzilla but for expectant parents? Because he's like that. Super anal about everything, down to the tiniest detail. Everything they buy from blankets to cradles to pacifiers goes through rigorous investigation, he reads instruction manuals and manufacturing info cover to cover, and he is extremely strict while choosing everything. He's already making a road map they'll need to follow to put their kid on a path to proper adulthood: they'll need to make sure they build the little one's confidence with children's groups early on, and make sure they are always readily available for the first several years or else the baby could develop attachment issues. They'll need the kid to be learning their glyphs by X age, and to be able to count by the time they're Y. He's narrowed down a list of acceptable schools for every age range, as well as researched the possibility of homeschooling just in case the public and private education institutions don't live up to his high standards. He spends a 20 hour period doing nothing but reading every recent study on sparkling psychology he can find, and he's already reserved a private room at the best hospital Cybertron has roughly around the due date.
Lockdown is honestly shellshocked. He gives me the vibes of an old fashioned, small town or perhaps country mom: as long as his kid is well fed and isn't bleeding and has a smile on their face, he knows he's doing alright. He'd definitely have a more hands off approach to parenting, letting their baby explore and make choices for himself. Isn't that enough to build confidence? Prowl rebukes him saying they're going to responsible for a living person, and they owe it to their sparkling to give them the best possible life. They're making the decision to bring them into this world, a decision that the baby has no say in, so they should at the very least give them the best possible chance to succeed and live an easy life.
To keep him busy, Lockdown let's Prowl take the reins on the majority of the prep. If he wants a fancy stroller without a certain strain of plastic in it, that's fine. If he wants to flip through hover cradle FAQs til his optics cross to find the most perfect one, so be it. It keeps him busy, and Lockdown honestly doesn't care about make or models or even color schemes. He's not too fussed about what they get, so long as baby is happy and healthy.
When the big day comes, Prowl thought he was prepared. He had everything squared away, had prepared extra energon and an overnight bag for the hospital and had transport on standby. He'd gone over his checklist every day since they enter the last few decacycles leading up to the due date.
But then Lockdown starts having contractions and he fucking blue screens. He's been running his systems so high strung and stressed that when the actual trigger happens, his processor crashes. Like actually crashes. Lockdown just grunts and presses a servo into his belly, gritting his denta and saying, "Yeah, it's time for the hospital, darlin'." and Proel gives him that standard deer in headlights look, optics flashing brighter than they ever had and something audibly pops in his helm. His lights go out and he drops like a sack of flour, smoking a tiny bit, and Lockdoen sighs. Rolls his optics, picks Prowl up under his arm, and heads to the hospital on his own.
Prowl comes to about half a megacycle later, once they've already been checked in lmfao. He's such a mess, he'd be drenched in sweat if he was human, and Lockdown nor Ratchet have ever seen him this flustered. Ratchet is delivering because Prowl insisted: there's no one better to do the job, and he'll trust no one but the autobot's CMO. Primus knows Ratchet is the only person Prowl would trust to save his life in a dire situation, he's the only one that Prowl trusts to safely deliver their sparkling.
He's pacing all over the delivery room, going over his checklist and feverishly looking through their hospital bag, so grateful that Lockdown grabbed it. He apologizes profusely for fainting like that, but his partner isn't fussed about it. At this point the contractions aren't painful, just a bit uncomfortable, and Lockdown switches between laying in the berth watching TV and doing laps around the room with his mate for several hours. It's his first sparkling, after all: it's going to take a long time before the sparkling is in the right position and his body is actually ready to deliver. It's a rather long labor, thankfully uncomplicated, but they're at the hospital for about 15 hours before they actually get to a point where they can start pushing.
Prowl, thankfully, doesn't pass out again, but has no idea what to do with himself while the medical team is setting up the stirrups and taking measurements and telling Lockdown to get ready to push. He's not sure if he should stand with his partner and hold his servo or if he should stand behind the doctors and watch firsthand as his sparkling is born. In the end, he does both, standing parallel to the berth with his left servo holding Lockdown's, the other peering over the privacy screen and watching the very moment their sparkling is born. Lockdown handles his labor like a champion, pushing out an exceptionally chunky sparkling in less than 15 minutes.
Their son is a big, round little marshmallow, black and white with a set of little green horns and huge blue optics. He's healthy and strong, latching onto his carrier's fuel lines without issue. Prowl is mesmerized by him, he's so proud in that moment, and Lockdown is on cloud nine cradling their newborn. He's so cute. So round and warm and snuggly, he never wants to put him down. Prowl's plans have all gone out the window--yes, he even had strict plans for post-emergence bonding--but he's lowkey short circuiting. He looks so tiny being held in his carrier's arms, and there's not a coherent thought in his head while he watches his son, mystified. The first time he holds him, he nearly crashes again. It's a good thing he's sitting down 🤭 the baby happily snuggles against him, content and starting to blindly suckle at his chassis in soft, wet kisses searching for more fuel. Prowl hasn't cried a day in his life but he gets damn close in that moment, and immediately turns to Lockdown to utter a heartfelt, whispered, "Thank you, for giving us this miracle."

Adventures in soldering
Tumblr media Tumblr media Tumblr media
Do not click on the images to make them large. The iPhone 15 Pro Macro mode looks good at pretty much exactly Tumblr image size, and deteriorates rapidly if you look at all the pixels.
Anyway, I tried something weird. For the model railroad streetcar project that I keep talking about, I want to light up the destination display, and that works best if I can find a side-emitting LED that is at most 0.5mm but not very wide. The problem is that side emitting LEDs are rare; most standard electronic LEDs, in particular the tiny SMD ones, emit their light to the top, so I had a bit of a problem…
…until I remembered that any LED is side-emitting if you just put it on its side and solder it in like that. Which was amazingly basically no problem at all (note: Requires at least cheap precision ESD pliers and a binocular microscope and some experience). The LED has size 0402, which means 0.04 inches long and 0.02 inches wide, or in reasonable terms, a millimetre long and half a millimetre wide (and about as tall). There's a picture with the standard cent coin for scale, but all of that is very tiny.
I am happy to report that this worked on the first try, and I managed to not drop any LEDs or resistors, which goes to show: Soldering is a thing you get better at through practice. I certainly used to think I was no good at it just a couple of years ago.
As for the circuit board, I designed this a while ago specifically to challenge myself. I did manage to solder in the 0201 resistors, but I didn't have any 0201 LEDs, and now that I do have them, I have been too scared to use them yet with their weird contacts on the rear instead of sides.
By itself, this is functionally useless, but it means that I will be able to use this technique for the streetcar project. Next time I'll try taking better pictures, though.

Smart Tweezers ST5S vs. Conventional Multimeter: A Smarter Choice
Smart Tweezers ST5S and conventional multimeters are both essential tools for electronic testing and troubleshooting. However, they differ significantly in terms of functionality and ease of use.
Smart Tweezers ST5S:
All-in-One Design: Smart Tweezers combine a set of high-precision SMD probes and a digital multimeter into a single handheld device. This streamlined design simplifies testing and eliminates the need for separate probes and multimeters.
Automatic Component Identification: One of the standout features of Smart Tweezers is their ability to automatically identify and evaluate SMD components. This saves time and reduces the risk of human error. The device can recognize resistors, capacitors, and inductors.
Ergonomic and Portable: Smart Tweezers are easy to handle and operate with one hand. Their lightweight and ergonomic design make them a preferred choice for professionals and hobbyists alike.
Real-Time Measurement: These tweezers provide real-time measurements, allowing users to monitor changes in component values as they troubleshoot. There's no need to disconnect and reconnect probes repeatedly.
LCD Display: Smart Tweezers feature a clear LCD display that shows component values and measurement results. It's easy to read and interpret, even in low-light conditions.
Conventional Multimeter:
Multiple Components: A conventional multimeter typically consists of separate probes and a central unit. It can measure a wide range of electrical parameters, including voltage, current, resistance, capacitance, and more.
Manual Range Selection: Conventional multimeters often require users to manually select the appropriate measurement range and function. This can be time-consuming, especially when testing various components.
Limited SMD Testing: While multimeters are versatile, they are less suitable for testing surface mount devices (SMDs) without the use of additional adapters or fixtures. This can add complexity to SMD troubleshooting.
Complex Readings: Interpreting multimeter readings can be challenging, especially for beginners. Users must understand the correct units, ranges, and measurement modes.
In summary, Smart Tweezers ST5S are a specialized tool tailored for SMD component testing, offering automatic identification and real-time measurements in a compact and user-friendly form. They are ideal for users who frequently work with SMDs. On the other hand, conventional multimeters are versatile devices suitable for a wide range of electrical measurements but may require additional tools for SMD testing.
The choice between the two depends on your specific needs and the types of components you regularly work with.

One sticky problem I've been having with IEM design is that it's hard to prototype crossover circuits with how finicky SMD components are and how delicate the soldering has to be. This mf is using normal ass regular sized resistors and caps and alligator clips and it's working just fine, I feel like a total rube

Enhancing Efficiency: Best Practices for SMD PCB Assembly in 2024
SMD is also known as Surface Mount Device. It is an electronic device. SMT (Surface Mount Technology) is the technique that is necessary for the production of SMDs on a large scale. The PCB SMD assembly technique is famous for various reasons. One is its high efficiency, and the other is its wide range of uses.

lol, the thing with the SMD fem-skeleton inside a male doll is even dumber. When you know that 1) SMD have notoriously shit joints. Anyone I've asked about them has mentioned how quick the joints are to crack, and break when using, especially if you use a little too much force. Even when you're just having a female doll with the female skeleton. So you literally have a design, fem-skeleton too small for male body, which literally forces you to use a level of force these doll's joint can't actually fucking handle.
2) All that considered. With the note that disabled people are to piddly and weak, and how they're not the intended target because they can't even play with the dolls right. So why the ever loving fuck would you aim these creaky cracky dolls to fucking children? Notorious for being pretty hard players, but not exactly the strongest in terms of actual strength needed to put these dolls back together?
Ranty Aunty rant: Just fucking saying. But you have an incredibly ableist note, that tells us that because disabled people are basically too weak to properly play with the dolls in terms to reattaching body parts. But for some reason that doesn't apply to children? Which on the website are prominently features as "our customers", and who mostly look like they're between the ages of 8-12? Which is like the weakest level of human can be, while not still being a toddler. As if a fucking 8-12 year old would universally be more adept at putting together a doll that's this shitty in terms of cracking but also force needed, than like every disabled person out there. Just to specify, the "fuck off disabled ppl you suck, don't buy my dolls" note, wasn't aimed at a specific group of disabled, it basically covered anyone with a disability who might have the tiniest problem playing with these shitty dolls. Just fucking saying, this guy thinks that some pre-teen little kids are more worthy to play with these dolls, than any disabled person with motor-disabilities. I don't wannt know what would happen if some disabled kiddo wanted to play with these dolls. I bet the little urchin would get pushed down a cliff for the audacity.

JP-800000000000000000000
Haha not really, just the JP-8000.
Tumblr media
I was surprised to see these things are going for over a grand now. Last time I checked they were half that or less. Why the jump in price? Hmmmm. Anyway this one came from Mercari. The seller described it as functioning but with no output, headphones ok, low battery memory corrupt! message on power up. A wee bit of google sleuthing and I found a fix, so I bought the synth and ordered parts. The low/zero output culprit is this guy.
Tumblr media
Capacitor 219. A 16. 22uF SMD weeee little fucker. Screwdriver tip for size comparison. The component is 5mm wide. Here's the mainboard after I removed the bad one.
Tumblr media
You can see two solder pads there above the white connector, just below the center of the photo. While desoldering the capacitor, the tell-tale stink of a bad cap wafted up and nearly gagged me. Yuck.
Tumblr media
Different angle, with the new one in. I used a 22v 22uF part because I read that the circuit is running at 15v and that's close to tolerance for a 16v cap so there you go. Man was this a bitch to do, my goddam hands are shaky as fuck. While I was at it I thought I'd recap the power supply.
Tumblr media
Had to do some creative component placing as I'd ordered 35v versions of everything so the parts were physically much larger than the factory stuff. I did find that the wee one on the right you see there, the 35v version was too fat and stout so it wouldn't fit in there with the two tilted over ones, but a search in the parts bin uncovered a 16v one so I went with that. Let me add that getting the power supply BOX out of the synth was a bit of a pain in the ass, as it is this huge metal high-sided tray kind of thing, and to get to the power supply board you have to remove everything that's above it, see here:
Tumblr media
There's a PCB with the power switch and socket for the plug there, and another PCB with an IC that needs to be screwed to the chassis of the power box thing. Pain in the ass, but just takes time and attention to get done. In the end, the thing works fine now. I'll probably mess with it for a few months and then sell it, who knows.
Meanwhile, I've been playing a lot with the JD-08 and the JX-08, slapping them into the K-25m keyboard and doing sound design with the thing on my lap. I was really impressed with the JD, so much so that I've decided to sell the JD-800 I have. That thing is a tank. SOOOO big. But yeah Roland really nailed the JD-800 sound with the JD-08. And it's got lots of polyphony as well as a B memory bank, so it's like having a card with the JD-800. I wish the sliders were just a but bigger though. Fuck those things are tiny!
That's all for this time, my invisible pals out there in internet land.
