I have a scope set up on this CYMA CM.401 airsoft MP5 replica. It's compatible with 11 mm rails by default, hence the adapter between the scope and the 22 mm MP5 rail.

I've lost one of the... "clamps"(?) for the adapter alongside the screw a few months ago in an airsoft match, and I thought that I'd get by with just one screw since "oh come on, it's just an airsoft gun", but it turns out that even on an airsoft gun the force from the electric motor is enough to throw the scope's aim off with only one screw.

I want to purchase a replacement "clamp" (and a screw if possible, but not necessary, since I can just borrow one from my red dot), but I don't even kinda know where to start looking for one. Can anyone help me out?

On every nutrition label (on the ones i've seen at least) there's a section called "Carbohydrates", and right under it is "of which sugars"

For example, this pack of chips I have lists that in 100g there's 61g of carbohydrates, of which 2.4g are sugars (speaking of which, what sugars are these, even? monosaccharides? polisaccharides? both?)

And that made me wonder - what makes up the other 58.6 grams, and what purpose do those carbohydrates serve in the body? I'll admit that I'm really inexperienced when it comes to stuff like this, so apologies in advance if this is something really obvious.

I've been looking to move on from membrane keyboards and go mechanical, but no matter where I look literally every mech has some form of obnoxious RGB lighting on it. Are there any that just.. don't have it?

I'm trying to mount an action cam to my FAST airsoft helmet, and I've got the j-hook baseplate already installed, but with just the baseplate the camera's FOV is still way too high.

I cannot bring the camera lower than this using just the baseplate, so I thought I'd just buy an extension that will let me swivel the camera further down, but I tried searching for it and couldn't find anything.

This is how I've got the camera set up now, and this is how I want it to be. I need the green part, which is just a male-to-female extension part, but I don't exactly know how to search for it, as anything I try comes up blank. I know this part exists, because I've seen it a few times before, and of course right as I try to search for it, it conveniently disappears as if it had never existed. Can anyone help me out?

EDIT: Thanks for the answers! Simply searching "gopro mount extension" was enough to find what I needed. I feel stupid now.

I came up with this question right after I wanted to take apart a microwave to see why it wasn't heating anything before I remembered that that's a very, VERY bad idea

Here's my previous post with a similar vibe.

This time I needed a cool background image for my website, so I made this one. 480x480 px original, upscaled ×4 to 1920x1920 using NN sampling. I needed the image to loop on the x-axis, hence the tiny amount of variety in the foreground. It also works as a nice phone wallpaper.

I got better at making clouds since the last post. Back then I was still tracing clouds from some photos I took (the clouds in the previous post were fully traced from a photo), but now I just need to look at a reference at most and go "oh right, that's how clouds look" to start drawing. I also got better at lighting clouds.

(TL;DR and update at the bottom)

Running a rooted (Magisk Delta) LineageOS 21 (ver. from 27 Sep) on a Motorola Edge 30 (dubai).

Managed to brick it by simply activating the "Invert colours" option in the settings. After doing so the screen has turned off and is unresponsive. Bootloader and recovery work fine. Booting into the actual OS shows the lock screen for a split second before the invert module activates and turns the screen off again.

Even though the touchscreen is unresponsive, the physical buttons/functions still work just fine (long pressing POWER toggles the flashlight as per my settings, and shaking the phone also toggled the flashlight before I rebooted the system). Upon connecting the phone to my laptop via USB, it shows up in lsusb, but of course doesn't mount itself since I'd have to open the USB connection settings window in the phone to mount it.

I did some digging and it turns out that this is a relatively common issue. My first instinct was to just go into recovery, connect via ADB and modify the settings file via adb push or adb shell settings, but my laptop is not authorised, so I can't do anything with ADB on it. Trying to authorize the laptop without the screen seems impossible. This, this, and this post, among many others, didn't work. Anything related to ADB might very well be out of the question, because even though adbd is running as root I still don't have access to any important parts of the file system without authorization (for reference, the /data, /sdcard, /mnt/system/sdcard, and /system directories, among many others, are empty). Editing prop.default or default.prop ADB properties to enable insecure ADB also doesn't work as upon rebooting the properties return to their initial state.

Screen duplication and remote input programs like scrcpy also don't work as they require ADB authorization to perform inputs.

I tried booting TWRP, but I couldn't find an image that could boot on the phone. Some got stuck on the boot logo, while some bootlooped ad infinitum.

I'd really like to repair this phone ASAP, as quite a few things depend on it and I was stupid enough not to make a proper backup, with my only one being my old phone containing data up to early September that I haven't wiped yet.

If I won't be able to do anything this week, I might be able to do something on the weekend when I get back home and hopefully use adb via my main PC, which should still hopefully be authorized. If it's not, I could try plugging an external display into the phone and/or a keyboard/mouse in order to authorize ADB.

I know posting this on Lemmy is a bit stupid considering how small the communities here are, but I figured it'd be worth a shot. If this doesn't work out I'll post it on XDA or StackExchange

TL;DR:

• Turning on "Invert colors" option in LineageOS 21 for the Motorola Edge 30 (dubai) turns the screen off and makes the touchscreen unresponsive while the phone is in the OS. Bootloader and recovery work fine.
• My laptop is not authorized to use ADB, and as such, I cannot access the file system to modify settings and/or recover data via ADB
• TWRP is not an option as there doesn't seem to be a valid image for my device
• Screen duplicating programs (ones that I know of at least) cannot work without ADB authorization
• I might be able to authorize the ADB connection by plugging an external monitor and mouse/keyboard into the phone when I get back home

I'm looking for a way to either revert "Invert colors" entirely or at least recover data from the device before I wipe it.

In order to do that I would have to:

• find a compatible TWRP image, OR
• bypass ADB authorization/enable insecure ADB, OR
• plug in an external input device and hope that it works (a keyboard would be the best bet)

Any advice is very appreciated

Update, 12 Oct 2024:

Unfortunately the ADB authorization on my main PC expired, and the phone didn't support video out via raw USB to HDMI, so I had to just wipe it. Thankfully at least I didn't lose everything because of my old phone that I haven't wiped yet, but still.

I did some testing after I wiped the phone and it turns out that the touchscreen is functional, it's just extremely hard to get any signs of life when you can't see fuckall. Likewise, the screen isn't completely turned off, just EXTREMELY darkened. At full brightness the bright blue header of the setup notification was visible with the setting turned on, which was enough to let me navigate back to the setting without much hassle.

If you're having the same problem, then genuinely try to feel your way back to the setting, this will be even easier if you happen to have a second phone with LineageOS (or any modern Android, really) on you that you can use as a reference. And of course make backups regularly unlike my silly ass. In fact, go do one right now. Just do it. You might thank yourself later. I know I would have.

I've been thinking about upgrading my electric toothbrush since my current crappy one is basically on death's door after a couple years of use. Is there like a toothbrush equivalent of a Toyota Hilux I should know about?

Just a random question that popped into my head while correcting a message I sent to a friend.

Posting for anyone who might like it.

I needed a wallpaper for a dumbphone I bought, so I made one, using one of my photos as a reference. The original is 128x160, this one was upscaled 8x using NN sampling for clarity

I managed to bag a Lenovo Thinkpad T440 for quite cheap as a replacement to my old laptop and I've been wondering about upgrading it.

Problem is the T440 is quite hostile when it comes to upgrading, unlike the T440p. Replacing, for example, the CPU is basically impossible as it's soldered directly to the board. And so I've been thinking about something stupid a.k.a. replacing the motherboard entirely with a T440s board, which has a better CPU soldered onto it.

In theory the two boards should have the same dimensions and should be interchangeable, but does anyone know if that's actually the case? I couldn't find much about this kind of swap online, so I thought asking here would be a good idea.
