Mine would be creating pen and paper ciphers for my made up secret communication needs.
I try to make something that looks good (or at least doesn’t look like random static) by running pictures I’ve taken through audio editing software. There are some extra steps that go into it to “trick” the program into importing the picture as if it were a sound file, making sure the header (information that tells your computer that this is a picture) doesn’t get fucked with, and then exporting the data in a way that it will be saved as a picture and not an mp3 or something else.
On the rare occasion I do bring it up, I can literally watch people’s eyes glaze over. Until I show them a picture
Edit: internet is really bad right now, will reply with an image when I can
Edit2: picture was too big at 7MB. Hopefully a screenshot of the picture doesn’t look too bad
Ok now that’s really cool
I do a lot of photography and I’ve been trying to find something that I could do with some of my more experimental shots that makes them more… more‡. If that makes sense?
You wouldn’t happen to have more details on how to do it would you?
Edit: ‡ My more experimental shots are more done as like experimenting with how a shot is taken for like evoking a specific feeling or doing something strange in camera or really any number of reasons. Hell some of my experimental shots were accidentally taken pictures that are disorienting or confusing. I don’t share them often, because IDK it just seems like really personal sometimes. Those experimental shots feel less like photography and more like painting with photos.
Absolutely!
I have a bookmark saved on my computer at home to an old forum with the instructions I followed when I started doing this, and I can send that link later.
There are two programs that I use, and both are free.
GIMP - image editing software
Audacity - audio editing software
Here is the basic process from that bookmarked forum post that I can remember off the top of my head. If something is wrong (especially the Audacity import settings, since I don’t ever change them), I will fix it later.
-
In GIMP (or other software of your choice) convert the image to a bitmap (.bmp). This step is very important!
-
Use the option to import raw data as A-law with “little endian” (I have no idea what those setting do, but I assume it’s for keeping the header intact)
-
Change the timeline in Audacity from time to samples and select everything after the 34th sample to edit and add effects (samples 1-34 are the information that tells your computer that this is a picture CHANGING ANYTHING IN THE HEADER WILL STOP YOU FROM OPENING THE IMAGE AFTER THE EDIT)
-
Export the audio using the raw data option, selecting A-law again. This should re-save the “audio” as a bitmap image as it will not add an audio file header to the data.
I believe the blue parking garage image uses reverb, or maybe a phasor… possible both to get that effect? But there are a lot of setting to mess with for each audio effect that can dramatically change the outcome. The trees picture was made by putting the original picture in the left audio channel, and putting a horizontally flipped copy of the image in the right audio channel. Delete the header from the flipped copy, and exporting the data smashes them together in this really strange mirror effect. Afterward, I would use GIMP for any color correcting, changing saturation/hue, simple stuff
Edit: spelling and formatting
Thank you so much, I’m going to have to give this a try when I get home from work
That’s pretty cool and definitely falls under the category of a hobby that you do because you can, although I’m sure there are people in the world who would pay for art like that (not suggesting that you do).
I have had the thought about trying to make money off of this, and some friends have joked that I should be making album art or something like that.
However, I don’t want to feel like I have to meet a deadline or feel the pressure of making something that someone else wants/likes. I just want to make something I like
Very unpleasant, basically just high pitched static. 1/10 wouldn’t recommend
It was! Taken during the winter so there were no leaves, and at night too
How much tinkering do they require to make the final product look like you want?
This is so fucking cool. Where can I learn more about this??
edit, I see your other post explaining!
Is there a way to convert an audio file to an image? Might be interesting for album covers.
I did try turning a song into an image last night, and it looked like TV static. Kinda disappointing, but I’ll try some other songs and see if I can mess with some settings
Considering it’s audio-software, I guess the changes are related to frequency changes. You should look up Fourier transform (the function that allows to see the sound frequencies of music, for example) applied to images and play with it. If you are not afraid to do a little bit of Python coding, you should be able to have much more control on the parameters responsible for the visual effects you’re looking for.
The image equivalent of bass frequencies (long wavelength) are big details (ex: the trees) and high frequencies (short wavelength) are small details (ex: the leaves).
I haven’t had to think about Fouier since college, so thanks for bringing up that trauma lmao. I do realize that there are ways to reliably get certain effects or even learn how to do this in Photoshop or GIMP, but I like the shotgunning, spray-and-pray of not knowing what the outcome will look like
I guess I find the process of going back to make small changes to the settings and then seeing how that affects the image more satisfying. Getting something that looks good is just a bonus
I am learning lockpicking for fun. It helps me relax. I used a practice lock at first, then a cheap real lock. I’ve just learned that my firearms lock…yup, can be picked open in about 10 seconds. Equal parts cool and terrifying. Locks are waaay less secure than people think.
It has the same “internet hacker” stigma so I avoid talking about it.
So got a question for you. I have wanted to get in to this - just as a curiosity. Is there an inexpensive set of picks a person can buy to get started with to play around with?
I tried googling and ran across about a hundred different suggestions and Amazon was the usual (no help).
If you’re familiar with the Lock Picking Lawyer, he has his own store and has some good kits.
https://covertinstruments.com/collections/lockpicks/products/learn-lockpicking-bundle
I’m not getting any sort of kickbacks from the link. I picked one of these bundles up and I like it. The lock it comes with is super handy because it’s designed to be re-pinned. You can change the pins without disassembling the entire lock.
Covert Instruments sells a kit with a pick, rake, turning tool, and a practice lock for about $10
I bought the Covert Instruments FNG (* new guy) set for $10. The Genesis set is $28 and is more full featured.
You almost only need the tension prybar + like 2-3 pins IMO. U bought a whole kit (cheap) and I use only the orybar + one of the pins.
I’ve had this small 5 piece set in my backpack since before instructions for anything could be easily found on the internet. It had to have been $10 or less.
I got into it a bit during COVID and practiced a bit on a practice lock that I could repin myself. After being able to regularly open it without too much trouble, I decided to try my front door lock - thinking it would be a much harder challenge since it was a real lock.
Nope. Shit popped open almost instantly. It blew my mind! After watching Lock Picking Lawyer, I figured that a skilled attacker could get into most locks eventually, but I didn’t realize that most house locks require virtually no skill to open. And it’s literally easier (and significantly less attention grabbing) than breaking a window!
Sorry police officer, but the door was open ajar so hrem I just wanted to check if everything was alright you see?
Had a guy just being mind blown for the whole evening lock picking my way into my apartment, and then open some lock he had on his luggage (all very basic).
Saw him a year later when I had forgot about it and he still was startled about the evening 😁😅
Lol that just reminded me of something only vaguely related. Back in the day I used to play a lot of World of Warcraft with a friend. One day in the middle of a gaming session, he went “HOLY SHIT! There’s a naked guy sleeping on my couch!”
A couple things to note:
- His couch and his gaming setup were both in his living room, barely 3 feet apart.
- We had been playing for at least 2 hours at this point.
My friend woke naked guy up, who was very drunk and confused. Apparently my friend kept his apartment door unlocked and naked guy stumbled in at some point, thinking it was his apartment, stripped down, and then passed out on the couch. Still don’t know how long he was there for, but probably several hours before my friend noticed
So yeah, lock your doors people. They might not keep out a thief, but at least you won’t have a random naked dude pass out on your furniture.
This right here is why electronic locks could be way more secure than mechanical ones, if only their manufacturers would hire well-trained programmers and not boot camp graduates to write the firmware.
I love lockpicking! It’s got a really nice tactile click when the lock opens. Too bad there’s not a lot of locks to practice on (legally, anyways)
And yeah, I agree - locks are really more of a psychological hindrance rather than an actual hindrance. Although, for what it’s worth, I don’t know of that many people who can lockpick, so in that sense, a lock at least decreases the number of people who can get through
That’s forbidden knowledge among the mechanics in my union local, lol. One of the shop mechanics at my training center was teaching some of my peers how to pick locks when we had completed our training and were just killing time helping the shop guys out. Had some downtime and he brought out a couple sets and some locks.
Apparently it’s sort of an unspoken tool of the mechanic trade when you work around machinery like that. Never know what you’ll have to get access to and you never know if anyone will have the right key. You’d think the ignition key would suffice to open, say, an access panel or storage cabinet, but some of these machines use a different key entirely for such a thing.
I’m a math teacher. I use my video game making knowledge from Godot to make little video games to review skills. Each takes a few weeks to make with game design, making all the art, programming, and making the worksheet.
Here is my Disco Dj-Demo if you were curious what I mean.
I think it’s fun, it’s not something I can really chat with others about.
You are awesome. Thanks for being a good teacher and making math as interesting as it is for your students. And your hobby is fucking cool too.
I am a programmer (as in it’s my job) and I can’t really program anything in Godot. I’ve done the dodge the creeps tutorial and did some more tries, but I don’t really get game dev. It’s definitely a unique skill.
I like learning about random ass hobbies without ever indulging in them.
I watch an ungodly amount of aquarium / terrarium videos, lurk a ton of aquascaping communities. I owned a betta fish in an empty bowl when I was 12 and that’s it. (poor fish)
I read all you could know about book binding fanfiction, never done it.
I read a hundred pages long horse breeding guide for the game black desert online and I have no idea why. I only played the game for a month, spent most of it reading a google doc about horse. I’m not even sure I owned a horse in the game.
Sometimes I try the hobby, for example mini painting, and don’t have the patience for it. But I still watch some random dudes on youtube paint for hours and sometimes they don’t even talk!
No idea why I am like this
Model trains. I don’t bring it up because it’s obscure, but I’ve definitely found there’s a stigma. “Oh he’s the guy who plays with trains”. Screw the haters, I like to relax after work and do a bit of escapism. Eventually I got over it though and talk about it with friends, but it’s not the first thing I bring up either
Let’s see those train pics, my dude! Let that conductor-freak flag fly here.
Not quite ready unfortunately, still in the “lots of pink fiberboard and paper mache” phase, but oh I will when we’re done. We’re probably too small for a model trains community, but I’ll probably be hanging out in !trains@lemmy.ml
Ha, and judging by the avatar you play video games with trains too! I adore Satisfactory
Most hours in a game by far, I think I’m closing in on 2 thousand. I’m slowly trying to kickstart !satisfactorygame@lemmy.ml again, come and join us!
this is a hobby I would absolutely love to get into but do not have the space (and renting a garage would probably not be realistic at this point for me). looks amazing dude I’m jealous of you! awesome hobby
My dad has been into model trains since before I was born. We built a train layout in the early 2000s when I was in middle school or so. Working on that project helped get me into electronics as we made PCBs for signals and control circuits. Now, 20 some years later, I work in software engineering. My dad wanted to get back into working on the layout and I’m helping him with Arduino programming and Raspberry Pi stuff. He built a stepper motor controller for the turntable and then we built some turnout and light control boards that interface with DCC. We set up JMRI on a Raspberry Pi to drive trains from phones and automate stuff. I also got him into 3D printing and he’s printed a ton of new scenery for the layout after buying his own Ender 3 after using mine quite a bit. We’ve learned various CAD/modeling programs to make 3D prints.
I also finally got to do something I always wanted to do as a kid, which is to drive the trains from a first-person view. We have gone through a bunch of different variations of putting a Raspberry Pi Zero and camera module on an HO scale railcar. We did some different designs. Our latest design uses an SG-90 micro servo to control the camera angle so you can look left and right. I also 3D printed an enclosure for a regulator, battery charger, and battery that takes track power and powers the Pi.
It’s pretty fun to be able to sit on the couch with a phone, watching the view on the TV, and drive the train from the other room including operating turnouts. Haven’t yet tried to drive the trains over the Internet yet but I want to, since I live a state away from my parents where the layout is.
Edit: Here’s a video of the camera car in action! https://www.youtube.com/watch?v=Ls-Rg1TlDOA
Very cool! Sounds pretty much like what I have started on mine, I went the full DCC++ route, have an arduino and rpi running the whole layout, with a few other boards helping along the way. At some point I’d love to do full automation of the setup but that’ll be a while. What camera did you use for the rpi and train? I’m running n scale so I’m assuming yours would be larger
We built the layout when DCC was first coming out after going to a train show. We ended up picking up one of Digitrax’s first systems (Empire Builder IIRC, with DB150 base station). That’s still what we use for DCC. I designed a LocoNet to serial adapter (MS100 compatible, but very cheap and simple) in college (2010 ish) and we’re using that to connect it up to a Pi 3 running JMRI. Our layout is HO scale. N scale is probably too small for even a Raspberry Pi Zero with camera module, as the setup barely fits on an HO scale car.
I have set up a DCC++ Ex setup at my house for testing and experiments. Just got a loop of EZ Track on the floor with an Arduino as the base station and another Pi with JMRI that is configured similarly to the real layout.
Here is an early picture of the camera car design with the servo. I’ve since condensed everything on to one car with a custom 3D printed design. I want to publish it eventually but haven’t had time. I even 3D printed trucks with power pickups in my latest design (just had to buy metal wheel sets to put in them). I also made a tiny Python webserver that has buttons for different servo positions so you can easily move the servo from a browser.
https://mastodon.social/@CalcProgrammer1/110456485998532640
For the DCC controlled turnouts, lights, and turntable, I built up an Arduino Nano based DCC decoder from a design I found online and a DCC decoder library that is available in Arduino. Since the layout spans multiple tables, instead of putting a DCC decoder for each table/PCB I just had the one decoder echo the DCC commands as serial messages over a serial bus that spans all the tables. The other boards (turnout controllers, light controllers, and turntable controller) all just have their RX pins wired to the decoder’s TX and can receive commands that way. Turnout controllers are a mix of SG90 micro servo based ones and L293D motor drivers for Tortoise switch machines. Light controllers use transistors to switch 12V outputs on and off to drive bulbs and LEDs. Turntable controller is an EasyDriver based stepper controller with some pre-programmed position offsets for each turntable track (each track position is mapped to a DCC function address).
If you can figure out how to relate model trains to the average person, then it becomes really interesting.
Like if your experiences have showed to you about why a trip cross-country in 1 country is so long compared to another. Maybe city planning, or at-grade issues that need resolution are the culprit, etc.
I’m into model live steam engines, I’ve dreamed about a model live steam setup but never had the room (or funds) for such a build.
