I used degreaser, but it left a black grease. I removed the small gears in the derailleur and used degreaser, then scrubbed with white spirit and then with isopropanol. But I didn’t soak it, because I heard it can dissolve the grease in the bearings.

I was told that the small gears in the derailleur should not be put in white spirit or acetone, because it would also remove the grease in the bearings.

I am on a tight budget, therefore I want to save a little money and use the cassette as long as I can. But I also thought about just replacing it…

Cleaning a bike for waxing, still some grease left. What to do?

Cleaning a bike for waxing, still some grease left. What to do? - Lemmy.World

I want to switch to wax. For preparation, I am cleaning my cassette, the gears in the bicycle derailleur (and the derailleur frame), and the bicycle chainring (I don’t need to clean the chain because I am getting a new one). For the job, I got white spirit, isopropyl alcohol, and a brush, and I cleaned them as well as I could, but, for example, on the cassette there are still some black dots left and, when touching them, they are still a little greasy. How clean do the components need to be, and how can I get rid of the leftover grease?

Thanks for the advice. Do you have suggestions how to setup/handle the backup? E.G. manually connecting the drive via USB and cloning the files via rsync/ borg, e.g. every week or every time a threshold of changes have been made? Or having a small extra machine with the backup hard drive and sending the files via the network?

I am also still a bit confused. I have 2x 12TB. Lets say I have 6TB files on my hosting drive. AFAICT can I have two backups/snapshots before the third backup needs to override the first backup. Or am missing something? Buying more drives for backup is not really doable, as drives do generally cost a buck and I cannot/ don’t really want to afford buying more drives.

RAID or Backup? What do you think would be more appropeate for my use case?

RAID or Backup? What do you think would be more appropeate for my use case? - Lemmy.World

I am mainly hosting Jellyfin, Nextcloud, and Audiobookself. The files for these services are currently stored on a 2TB HDD and I don’t want to lose them in case of a drive failure. I bought two 12TB HDDs because 2TB got tight and I thought I could add redundancy to my system, to prevent data loss due to a drive failure. I thought I would go with a RAID 2 (or another form of RAID?), but everyone on the internet says that RAID is not a backup. I am not sure if I need a backup. I just want to avoid losing my files when the disk fails. How should I proceed? Should I use RAID2, or rsync the files every, let’s say, week? I don’t want to have another machine, so I would hook up the rsync target drive to the same machine as the rsync host drive! Rsyncing the files seems to be very cumbersome (also when using a cron job).

I just tried it. When using it (in a bright environment, had no dark environment/ night at my hands) the time to take the image felt like 1s max. So not that much longer. Also I would like to control the exposure time…

Exposure time/ shutter speed is capped

Exposure time/ shutter speed is capped - Lemmy.World

Why is the exposure time/ shutter speed for my phone capped at 1/2 (half a second)? I would like to take photos with an exposure time of up to 30 seconds. Even when installing other apps, like GCam or Open Camera, it is not possible to increase the exposure time. I have an Fairphone 4 with Android 13. In the screenshot you can see that the exposure time (S) is at the maximum value. [https://lemmy.world/pictrs/image/208b9a6a-d7a4-468f-8aaf-f85d7fd7d621.png] Do you have the same “issue” as me, or know how to fix it?

Where do I get some "normal" Keycaps, like in the image?

Where do I get some "normal" Keycaps, like in the image? - Lemmy.World

I am living in Germany and I need some Keycaps, which are not expensive. They don’t need to be special, they just need to… work.
