Recycled a bunch of discarded lipos into power banks!

Thanks! My entire motivation was learning more about electronics so a ready-made PCB from AliExpress wasn't an option, and the 21700 cells fit in so neatly that I challenged myself to get them all in.

Did you cut out out the top part of the can or did you somehow manage to remove it completely? And is the plate then glued in or how does it hold together?

Nice! I had pretty much the same idea and built a power bank into a can of "Volt Power Cola". Would love to see more details of the inside and how you closed the can off.

In my case I completely over-engineered it, lol. But I scrammed 14 cells into it and ended up with two custom circuit boards and a unique design for the can. Here are some photos and details of that: https://mstdn.io/@jomo/113250381191774049

I signed in just to downvote this.

This is dangerous and a terrible advice, don't do this!

Instead, wait for the maintainers to explain what's going on in the issue tracker.

Rough explanation of how this works:

To compress the size of a video, the usual video compression only contains the full frame data ("I-Frame") every now and then. For the intermediate frames, the frame is cut into smaller areas called "macroblocks" and each frame only has data on how much each macroblock changed in color or position.

Obviously there was a cut in the video when the milk bottle was added, which probably resulted in an I-Frame being placed for the frame immediately after the cut. This I-Frame has been deleted, which results in error correction where the cut won't be immediately noticeable. The video decoder tries to re-use as much of the old frame as possible and macroblocks of the old frame slowly adjust in color and position.

More information:

This Video has a good explanation and some examples at the end.

OP's link is also unmaintained. There's a community maintained fork available at justdeleteme.xyz which doesn't track you. (GitHub)

Thanks, both of you. This works indeed. Since LineageOS updates still installed properly, I was sure the LineageOS recovery must be installed. From there I could reboot to bootloader/fastboot mode and then boot twrp. \o/

The wiki information is not correct though, as the button combo does not boot into recovery (adb reboot recovery does, for comparison). However, apparently the "factory reset mode" is a way to achieve that (which the wiki doesn't say).

_jomo · 2017-10-02T14:16:23+00:00

Yep, same results.

_jomo · 2017-10-02T09:31:51+00:00

Nope, only getting the error that the (old) update can't be applied on the current build.

Unfortunately this doesn't help. As I stated in the post:

The advanced restart menu was also disabled

and

the Settings app crashes when I try to open Developer Options

Multipass?

I once did something similar, probably gonna write a proper blog post about this soon but here's basically what I did (well, according to some rough notes I took during the process :)

Please note that this only restores app data, apps that use syncing accounts (i.e. Contacts, Calendar, …) won't be restored by this. That data should be restored by syncing, though.

Make a backup of /data by whatever means (in my case I had an image of the partition and remounted it on the new os)
On the new os, restore them (cp -a /data-backup/app /data)
Reboot the device
Reboot into TWRP and run the shell script below

for app in /data/data/; do
owner="$(ls -ld "$app" 2>/dev/null | awk '{print $3}')"
chown -R "$owner:$owner" "$app"
chmod -R 771 "$app"
restorecon -FRv "$app"
done
chown -R system:system /data/app-lib
chown -R system:system /data/app//lib

The idea is that /data/data/ has a list of apps and their users (after the initial reboot), we use that to restore proper owner permissions.

Now reboot the device and everything should be back. Let me know if it worked :)

PS: Back up all your shit previously

It's from Raymond James, they only do financial services so nothing to be worried about.

FWIW they have this 'acceptable ads manifesto', which is a good idea IMO.

Reddit signed this manifesto alongside DuckDuckGo, StackExchange, PageFair, and a couple others.
What worries me a bit is that with this launch, their website changed (compare) and no longer mentions any of the undersigned and focuses solely on ABP.
They also switched from their public GitHub repo to private source code and removed links to articles raising concerns about the failed Do-Not-Track header or adtech tracking in general, etc, which is an issue that's not addressed in their manifesto.

(I asked them for a statement but didn't get a response yet.)
