Moira Rose is DEAD!
I might have to go back to an older version of the pi os.
It seems that they removed the old "raspistill" / "raspivid" without actually having a fully functional replacement that actually has the same or better features.
They then removed the legacy camera option from the os start with bookworm. Which is what im using.
I have no idea what fucking idiot decided "hey, lets get rid of the old, functional way of access the camera and replace it with a new, non fully functional way"😒
Ive swapped the LED panel backlight thing i was using, I don't know how i didn't notice it before, but its a really bluey white, its not just white.
I changed it out for the way the original design had it, it used an mr16 12v 5watt light, but with 5000k color temp, I ordered some 6000k because i couldn't find any on amazon that would be delivered within the next few weeks. What arrived was a 6500k... so yeah, im not sure how its gonna look.
Also, unless im using the wrong search terms, i could not find any white diffuser sheets on amazon, except one, which was like 5ft long and i literally need a 2 inch circle of it😭
I ended up using a sheet of plain white paper in the end. It looks ok to the eye, i haven't looked with the camera yet.
Oh, i will say... despite being LED, they get fucking HOT, I ran one earlier for about an hour whilst i was working on the GUI and it reached 90c... I have no idea how the printed holder for it will hold up for at that temp, im pretty sure PLA glass transition temp is like 60c.
Oh, talking of the GUI, Ive moved to useing .net and Avalonia. I really tried with python but i just cant, i hate every second it. The icing on the cake being installing pip packages without using a venv, If you try, you're met with "YOU CANT DO THAT, IT WILL BREAK THE OS" bullshit. So fuck em.
The new gui is ugly af, but meh, it aint for looking at, its basically for pressing start and viewing the camera. I have the motor driver stuff all setup, but i havent touched the camera side of things, im kinda dreading it tbh, i know .net can work with the camera, but i dont know how nicely it works with it.
Like i said, ugly af. But its a work in progress, so 🤷♂️
Ive been trying to do the code for the film scanner, but i just cannot find the motivation. Like, i want to do it and get it done, but everytime i start, i just get lost.
Im seriously considering just using .net gui on linux. Avalonia or something.
Just thinking about the times i played dayz with Alex. One server in particular, I wanna say it was called dayzsos, but dont quote me on that.
Anyway, we used to hang out int he safe zones, make friends with people, then lure them out of the safezone to there base, murder them, steal there shit, and go get changed, then hang out at the safezone again. After a few weeks of doing that, The server admins called a meeting of all players at the safezone, Not really knowing what it was about, we showed up. it eventually turned out to be a talking to about the rules, and what is and isnt allowed to happen at the safezone and the area surrounding it.
It got boring pretty fast, They had these stupid blue helmets and vests on, and would not shut the fuck up. They had maybe... 15 players there and all 10 ish staff. So Alex said he was gonna start causing issues, and for me to go get a gun. So i ran to a barrel we had buried, grabbed a AR and ran back to the safe zone, Sneaked up behind the admins and just opened fire 😂
I think i killed all but 1 of the admins, and like 4 players. The remaining admin killed me.
When things calmed down, alex picked up one of the admins guns and killed the rest of the players and the other admin.
We got banned from the server about 10 minutes later😂
Motor current has been set, im just putting off the code side of things😭
Those of you with eyes may have noticed that i fucked up the 12v wiring for one of the stepper drivers😑
Lets hope it didnt cause any damage.
I need to set the current for the stepper drivers, but i dont wanna get my multimeter out😭
I wonder how long it will be before google puts an adblock clause in its terms of service.
This is how the film thing currently looks.
Very slowly putting the scanning together, im just dreading the code side of it, i know the github has code, but his setup is a bit odd, from the looks of it, hes running a RAMPS board, connected via usb to a raspberry pi. Which i find... odd. I suppose its just a case of using what he has, but yeah, im gonna be skipping the ramps side of things.
I use this little driver boards that work perfectly well, and ive used them on multiple projects, so ill probably stick to them 🤷♂️
i wonder if you could detect a camera flash just before the shutter fires, and use it to switch a bright ass light on to block there camera🤔
Ive been printing parts for Stuart Pittaways film scanner, its mostly constructed, but i gotta get the raspberry pi setup, and i hate working in linux 😒
I was just looking at the last film scanner design i made.
I used some rubber rollers that they use for ink, so i figured when i look at this, the rubber is probably going funny or deformed or something from the constant pressure applied to it, But nope, it looks in pretty good condition.
I took a couple of pictures of it, just so you know im not making it up lol.
This is the main box, i have marked the film path. There is 5 rubber rollers, one for the entrance hole to stop the film from bending, 2 for the inside of the entrance hole, they help feed the film into its little channel, and the two rollers on the right, one is spring tensioned against the other, with the bottom one being driven by a nema 11 stepper motor.
When i just looked at the design, i thought.. "this is like 99% done, why the fuck did i stop". Then i remember it was because of THIS monstrosity.
It should be fairly explanatory, and it works, except that any movement at all, even just a breeze, seems to move the camera enough that it produces unusable images like 50% of the time. I cannot work out how to have both a rock solid mount for the camera and lens, but also have it adjustable.
You can see the screw holes i have in the very top part, they was there to try and prevent the movement, do they? no, no they do not. even with 32 screws (yes i tried it), there is movement. I dont know how, i dont know where, or why, but there is movement and i cannot get rid of it.
So ive found a project by Stuart Pittaway https://github.com/stuartpittaway/Super8FilmScanner
Im printing the parts now, Hopefully its way more stable than mine.
Thats why i was looking at my design, to "borrow" the raspberry pi and stepper drivers from it.
Just finished capturing a tape, it has a lot of Christmas ITV 2003 content on it, including adverts. The quality looked surprisingly good, If i remember, after decoding ill post a picture. The capture size is 250gb😭
Ive been researching the scrambler / sizzler / twister. Im just gonna called it a twister from now on, its what ive known it as most of my life.
It surprisingly difficult to find anything on the modern versions of the ride. There is a few patents out there for the very early models by Eli Bridge Company (i think), And they are pretty detailed, but if i build one, i kinda wanna build one of the ones im familiar with, which is the trailer mounted rides that are pretty much an all in one, Not the "Scrambler" version, which sits directly on the ground with no platform.
Something like this
These captures take up so much fucking space its crazy, and im only doing 30-60min captures, some tapes can be 6 hours.
For example, a 32 minute capture took me 6 and half hours to decode.
With the parallel scripts i mentioned previous, it still took 2 hours, but thats still a pretty long time😒
Im getting that waltzer itch again. I have basically finished the vhs project, most of the time spent on that from now on is capturing and "decoding". so not really an "active" process.
I do wanna try the 8mm film scanner / digitizer project again. I didn't really finish the last one, simply because i couldn't find a way to reliably mount the camera that doesn't result in a ton of movement which is very apparent when focused on such a small area.
I have seen a couple of 3d printed projects online for it, but i dont have most of the stuff they need as they seem to have gone with some weird off choice in components, and one needs a custom pcb, and i dont particularly wanna drop £40 including shipping on a single pcb for a project im not even sure i would be happy with.
I have designed like 3, all of them worked to varying degrees, but none of them i was happy about.
I would like to design one where the camera doesn't need to be 50-100mm away from the subject, because thats when the wobble becomes noticeable. And i dont know enough about photography or math to calculate the exact location needed for the lens / sensor. If i could, then i could just modify my current version i made... maybe there is an online calculator? hmm
Just had my first tape jam, Its not always nice to have stuff neatly organized and tidy... especially when you have to take the fucking vcr apart😭😭
But i dont have an adblocker on youtube... its on my browser 😂
