Not a JPEG file: starts with 0xc8 0x48

Hello everyone.
I got a quite large rar file of images a while ago.
Finally got around to opening and sorting that, only to learn there are three types of file inside:
.rar that unpack without issue.
.rar files that unexpectedly demand a password (bummer)
.rar files that unpack into the expected structure and naming of files, making it look like there is a whole bunch of .jpg but no program I tried is able to read them, the title being the only legible error message I got.
Has anybody encountered this? Are they unrecoverably corrupt? I couldn't find any image formats that match this file start. Notepad turns them into mostly chinese gibberish, Notepad++ turns them into some sort of Wingdings gibberish.
Thanks in advance.

Look I created for a photoshoot

Shoes: Unchanged
Pants: Bought two, because I wanted the pattern, but hated the fit, so I changed the narrow legs to somewhat bell-bottom shape, turning two into one.
Sports bra: Unchanged, needed to be there bc ...
White hood thing: Has giant cutouts from the side. Added Iron-on patch
Jacked: Turned a Motorcycle jacket into a crop-top. Just noticed that the custom made patch on the back comes across in exactly zero pictures. Oh well.
"Cyberdeck": Printed this file , much sanding, painting, cursing. No actual computing power inside, just a LED video light panel. Custom sewn lanyard (is that the word?)
MakeUp: Designed and soldered the heart-patches for the first look. Power supply came from LED-lashes (those where a short lived craze, I think). Both MakeUp looks where done by a MakeUp artist, I can do a lot, but that's black magic to me... apparently caused her to go down quite the rabbit-hole with anti-facial-recognition MakeUp. (Doesn't work in practice, do not expect to deflock the neighborhood anonymously with some camo)

It helps, of course, to attach the whole assembly to an incredibly pretty friend of mine (I was the bearded dude behind the camera...)

Just found this subreddit. Some of you are very inspirational, some posts are quite bizarre to me, as I think Punk=D.I.Y.
Looking forward to seeing more of y'all :)

Girly3000 for OC Cyberpunk Character strw_brry (simple prop, nightmare difficulty)

strw_brry is an oc (original character) from my own cyberpunk writing project.

Hacker-girly looking for love in a cold city. So if you see her, with glowing heart stickers* under her eyes, and she smiles at you...well, then you where most likely deemed an easy mark and your money, access-permissions and personal data is currently migrating to her.

*Different prop shown here before.

The Girly3000

3D printed shell from a file I bought years ago, which in turn is based on the excellent "Mr3000" Design over on artstation.(Yes, I got very creative with the naming)

I started it then, long before strw_brry was thought off and needed equipment.

The file was evidently made by somebody (I forgot to note the creator, sry) who was very adept at making files for video-games. This doesn't translate well into a 3D print. Holes for parts shown in the render where missing, the hardware I got for it (RaspberryPi&touchscreen) didn't beginn to entertain the idea of considering to fit.

I was also much less experienced and created a frankly abhorrent paintjob.

Fast forward almost ten years and strw_brry needs equipping.

I go through my abandoned-projects pile and find the parts. Sand off the shitty paintjob, apply filler, sand it to 800grit till things get shiny. Apply basecoat, leave on balcony to dry. Come back to find that one of the hottest days of the summer has Dali-fied the PLA parts. Bite into table (Important step).

Well, I have improved much as a 3D-printer operator, and the printer I have access to also drastically improved. So reprint it is. After some very necessary edits to the file.

Starting the 20hour job, coming back the next day...print has failed halfway through due to a nozzle clog. Huh, that hasn't happened in a while. Bite into table (feel free to switch up the position).

Reprint for real.

Sand, fill, sand, make parts fit together at all, glue pieces which are supposed to be one. Fill. Sand. Basecoat, paint etc...

Notice that the electronics still don't entertain the idea of going in this.

Cut lightbox acrylic to fit and print some "screens" onto transparent plastic.

LED lamp for filming goes in with double sided tape.

Some hardware (real antennae, buttons, pink-eloxed-aluminium bolts) rounds out the look.

A whole bunch of Hello-Kitty Nail-Stickers add some visual interest. (Model was very happy, being sonewhat Hello-Kitty decorated herself, with two tattoos)

Good enough for a stage prop^^

Slicing for Mega X?

So, I came into posession of my first ever Anycubic printer, the Mega X.
All pretty straightforward, except: I can't find the damn thing as a preset in any slicer.
All my previous experience was with Prusa and Orca slicer, but no matter what I do, customizing the profile, the printer can't read the g-code file. This is also the case when slicing with Cura.
It registers that an SD-Card has been inserted, but doesn't show any file names.

The Loreley [Mamiya645, 80mm, f5(?), Fuji RVP100]

I asked about the softness of these images over a analogCommunity, and people seemed to like it, so here is more.
Loreley, or "The Loreley" was a folklore cryptid (I guess) who sank boats on the rhine.
She achieved this by sitting on a rock in view of the river, combing her long blond hair and looking pretty. Somehow she is blamed for dudes stearing their ships onto the rocks because they couldn't stop oggling her. victim blaming, if you ask me...
Current waterlevels on the rhine not withstanding, the only commonality between my model and her story is beautiful blonde hair.
Location is, btw. a 100% artificial waterfall set up in the late 1800s. You can see the tip of the Kreuzberg Memorial, atop the Kreuzberg (Cross-Mountain, bit of a grandiose term), in the Berlin district of Neukölln...the district next to the district Kreuzberg, named after...yeah.

The Lorely. Mamiya645 80mm ~f5 - 1/60s. HocusPocusWhereTF is my focus?

I am used to the Mamiya lens being SHARP. In the second image, you can see some 90s sitcom dream-sequence kind of focus.
Yeah, you can see single hairs, and there is nothing sharper anywhere in frame, so at least I didn't mess up the focus. This time.
Is it just the shooting somewhat into the sun?
Film was some Fuji RVP100 that I found in the back of my fridge, apparently best before 2017, time flies.

mamiya RB67 Lens repair manual needed!

Any of you fine people in possession of the repair manual for the lenses/shutters?
I would need to trouble Mr. Butkus with an E-Mail otherwise, as all other sources demand payment, and if I pay for a manual, I might as well support the OG^^

Okay Gang, what do we use to fill chonky 3D-prints?

This gap had been filled with automotive fillter, sanded flatand decided to open again under very minimal stress.

You can see also a couple of other seamlines here, where I decided progress beats perfectionism, but I could swear my wet-sanding ~400grit pass pulled filler out of some smaller cracks and seams.

First pass was spray-on filler, btw, which sticks without issues.

No clue whereelse to ask

This illustration is by DaveKeen on instagram.
I am a self-taught CAD user, and I like to make props for my photoshoots, which brings us to these goggles.
How do professionals approach something that is hard, yet conforming to the human body?
I had some old 3D Headsets to disassemble, sadly they are super bulky, owing to the reality of optics. Same for Goggles for FPV-Drones.
The closest I found was historic Inuit snow-goggles but even then: How to figure out measurements that are somewhere close to "fits on an actual human"
Decades of wearing glasses have taught me that designers do not consider my head-width, so measuring myself is kinda out.
Sorry for rambling and if this isn't the scope of the group, but I figured you are the kind of people that design swim-goggles and such^^

Prop design for a hot mess

Life story part of the recipe blog:
So, I do photography quite a bit, and I wanted something Cyberpunk-esque. I have more classic looks on that topic coming up, but my favourite book in the genre is "Walkaway" by Corey Doctorow.
In that, the protagonists do live in a world full of future tech and corporatism, but instead of joining a gang of criminals, they walk away from it all, into places nobody wants to live anymore, taking their 3D-printers, and Medication-Fabbers with them.(Which, of course, makes them criminals.)
First problem: It's a book with zero fan-art, scarce descriptions of outfits, and most of the time, the characters dress like somebody who lives in the woods. Because they do.
So I largely left outfit choice to my models, which left us with some rather fashionable walkaways.(Not complaining, it was fun working with them)
I am also kinda fond of the Nomads in Cyberpunk2077, so I wanted a desert environment, courtesy of the local botanical garden.
Hot tip: The greenhouse is not the place to be during a record-breaking heatwave.
They opened the windows and started the ventilation in the desert-house.
As it turns out, the "barely covered" outfit was the right choice, as she was the only one not completely drenched in sweat by the end.

Actual prop making:
The design is loosely based on the Cyberpunk2077 Radio you use in one of the earliest scenes.
I actually had a 3D printed version of that before, it was terrible to assemble and I found no way to light it.
This one, I designed around a cheap Aliexpress RGB-Lightpanel, simplifying the in-game design a little. Printed in PETG
Spray-filler, and sanding (Which idiot put all these little recesses in the design?? Oh, right...)
Sprayed it with "Gobi" from the Montana - Black line. I haven't got the fuzziest clue why one of the parts started developing scales. re-sand and re-paint.
Hit with matte-varnish, also by Montana.
The outer parts I wanted to look rubberized, so they got spray-on rubber (sold for car-rims).
Then everything got assembled and doused in thinned acrylic paint, some black, some brown.
The spray-on-rubber didn't appreciate that much, but it came out okay.
Everything is held together with a bunch of magnets, allowing me to put the LED light in and out.
My local print shop offers printing on overhead-projector-foil, so that's what constitutes the "screen"
I also put a thin piece of felt between the light and the "display" so the hotspots from the LEDs aren't that prominent.

Which coin was this designed around?

I heard "weirdly shaped screw slit" every old japanse camera has was originally invented to fit some specific yen coin.
I have a camera where that thing is plastic and already rather mangled, I would like to figure out the intended size and 3D print a mangle-less screwdriver for it.
Anybody got an idea?
Otherwise I need to turn some weebs in my friend group upside down, shake, and compare what comes out their pockets....

Jollylook is at it again!

Everyones favourite american/ukranian/or maybe slovenian camera manufacturer just dropped their latest release onto Kickstarter!

Sadly only backers can comment, although I really wanted to congratulate them on their smashing success with their line of Instax-Backs.

Incidentally, there is an option to report on the bottom of the campaigns page.

Apologies to the mods, I understand this is barely on topic at best, but I felt parts of the community might be interested in what jollylook does instead of delivering the products we paid for.

Sidenote: I am fascinated by their decision to sent not one but two ads regarding this campaign to me.

This is simple, right?

Sally Mann - At warm springs,1991
Do you think there is anything more than what I very artistically rendered in paint?
Am I off by a mile?
Heading to the lake on saturday and I can't get rid of the feeling that I'm entirely wrong.

EDIT:thanks to u/focusproblems who pointed out that I was right with the direction, but far off with distances and light source, as warm springs refers to baths with cutouts in the ceiling-domes

Jollylook is dead

Like many here, I bought the RB67 back in July 25, expecting to receive it, ya know, at some point.
Doing some CAD work myself, and actually having tried to make my own instax back, I understood some of the delay messages better than most, i.e. those screws are indeed unobtanium.
Well, the "This what happened" Mails ran out, and so did my patience, so I asked for a refund end of January. Exchanged a couple mails assuring me that my refund was being processed. Didn't turn up, so I asked if they could maybe find a supplier to blame for that. And indeed, it turned out it's the fault of the payment processing company. I received screenshots of the transfer order, that was end of february.
Seeing as their Insta is still reposting the video advertising the non-existent backs, I asked where my money was this week (may 26).

The answer contained this interesting paragraph:

>The reality is that refunds are currently taking much longer than they should because a large portion of the funds had already been committed to production before the manufacturing problems forced us to restart everything with a new supplier. That is not meant as an excuse, only an honest explanation of why the situation became so difficult.

To me that reads roughly as "We spent all the money, the company is broke and our only hope is new suckers will keep us afloat before the lawsuits start in earnest. You'll never see a product or your money, sucks to be you, we are the victims in this."

They are US based, but here in germany, a company that can't pay their bills is legally required to declare bankruptcy. Not declaring that, even knowing that money will be coming in, is considered a form of fraud. Anybody know if there is something similar in the US?

EDIT: Had a look around wanting to know how they are financed and such, instead found this 6year old post discussing how they use fresh campaign money to fulfill their promises to the old backers:

How to fake a screen?

How do I put a fake screen in here? I'm thinking plexiglass, Foil-print, white diffursor and a LED strip around the perimeter?
Anybody fakes something like this before? Tips, Tricks, Pitfalls?

While there is technically enough space for a RaspberryPi and an actual screen, the combo I have doesn't fit right side up. Wrong way around the ports are covered... Frustrating mess. Also not willing to drop a lot of money on a thing I will use for 1-2 Photoshoots

Edit: I am reasonably certain I badgered this gentleman for the fiels, back in the day...

Taught myself PCB-design* for this one.
27 tiny** LED placed and soldered by hand on transparent material curtesy of JLCPCB***
Hopefully soon going on the face of a model for a cyberpunk shoot... Model that hopefully looks less grumpy than me, in the process.

*I got called names in the KiCAD subreddit, so please don't ask me for design advice, apparently this will somehow burn my house down (They have many reasonable people there, but the unreasonable ones are REALLY unreasonable)

**0402 red (I also tried purple and pink. Purple turned out to be UV LED and kind of faint, Pink is best enjoyed wearing welding-goggles)

***Not sponsored, but damn they take care of people who don't know what they are doing. Also I need like 2 of these, minimum orders being what they are, I ended up with 125 for less than 40€

Shot on paper negative, attempted to develop on sight, first turned largely black in less than 5 seconds, it's the more streaky one.
Second I pulled through the developer and watched it turn much slower.
Both hampered by the fact that I didn't consider the tray size before starting.
Turned positive digitally

As my 30x30cm camera is scheduled to take it's first "Full format" images in less than a week, I talked to some friends and acquaintances about it (Couldn't stop me if they tried).
I mentioned the issue of having to design a 30x30cm holder and shooting on paper because... yeah, I don't have specialty-size film budget.
X-ray technician pipes up saying "Thats a pretty common format to do hand and feet images on, just get x-Ray film?"
Well, from what I saw they where partially right, the film is much more agreeable on the bank account BUT, the nearest common size seems to be 30x40cm. Couldn't find much in terms of experience stuffing it in a camera. Anybody here done this?
