Hello altogether, I guess everybody has some USB-C cables lying around, but wonder if it’s 3A, 5A, 3.0, TB… Anybody able to recomment a device able to determine that? Maybe also something that can be combined with a load tester.
There are simple testers like this. It’s rather overpriced for what it is, but it would be trivial to make one yourself. That will only do a continuity check though. If you want to know what the current or speed ratings are, you will need to read the chip in the cable.
A dedicated GPU will mean reduced battery life. If you are only going to edit video at your desk, I would suggest getting a laptop with a thunderbolt 3 or USB 4 port and an external GPU. Make sure the port provides 4 PCIe lanes, not all of them do.
Timeshift works best if you use BTRFS for your root partition because snapshots can be taken instantly. I have mine setup to automatically take a snapshot every day.
I got these TP4056 modules from an AliExpress vendor and fail to understand how the protection circuit works or if it’s just typical Ali shovelware. It could be my limited understanding of electronics....
The drains in the 8205 MOSFET are connected together internally. In a DW01 circuit, they are not connected to anything else.
One MOSFET stops the battery from charging and the other stops it from discharging.
The MOSFETs are in series, but in opposite polarities. Two MOSFETs are needed to block current in both directions.
The DW01 uses the voltage drop across the MOSFETS to measure the current. The overcurrent threshold voltage is fixed at 150mV. Using a larger MOSFET that has a lower RDS(on) will increase the current limit.
Since MOSFETs have a gate capacitance you’d want to limit the inrush of current from the output of a microcontroller to prevent it from getting damaged prematurely. That’s what gate resistors are usually good for....
For something that’s not switching at a high frequency, slow rise and fall times are fine as long as you are staying within the safe operating area of your MOSFET. A 10K gate resistor could certainly work, but it will depend on your MOSFET and load.
n00b question, sorry. If I had a desktop that could hold 4 HD and 2 SSD, could I turn it into a NAS? Could someone point me in the right direction if this makes sense?
Power consumption is the main issue. If it’s an old, power hungry desktop and you live somewhere with expensive electricity, it can be quite costly to run. If you have an energy efficient desktop or have cheap power then it will be fine. Just make sure it has a good quality power supply if it’s going to run 24/7.

I got an external hard drive enclosure for the purpose of recovering some of the files from my old laptops hard drive. The hard drive and all of it’s partitions show up in both disks and gparted but it wont mount. When I tried to mount it manually, it gave the error message stating that it can’t read the superblock. I’ve...
The hard drive should be connected by SATA or eSATA when making the image. Connecting over USB is just asking for more trouble when the drive is not working correctly.
Hi, everybody Recently, a guy noticed that I was using it and asked why? For me it because in Linux many things are done through the terminal because Linux has many different desktop environments...
The T480 and T580 are some of the last ones they made with swapable batteries. Everything works out of the box in Linux except the fingerprint scanner which needs some additional configuration.
I have a T480 with an integrated GPU and the largest battery. It runs for a long time on a charge and there are lots of spare parts available.
I still get over 12 hours of web browsing or video playback with the backlight around 30% on mine even though my internal battery is down to 60% capacity and my external is around 90%. Standby drains about 10% overnight. I am running Linux Mint on mine and I set up TLP. Undervolting can increase the runtime quite a bit, but I haven’t bothered with that yet.
I’ve gotten both of my thinkpads used, so none of that money went to Lenovo or Microsoft. The laptops that come with Linux are expensive and are rarely available used.
I’m learning about electronic components. I believe this is the part which has broken and made this heating pad unsafe to use. Well, unusable, not just unsafe lol.
MELF stands for Metal Electrode Leadless Face although anyone who has had the pleasure of working with them will tell you it stands for Most End up Lying on the Floor.
It could be resized too. 5120x1440 is way too big for a website banner. There’s no reason to go more than double the size it will actually be displayed at. That would bring it down to a couple hundred KB.
You’re probably not going to find a tablet with modular RAM, but 4GB will barely run a web browser these days. You will be using swap a lot and that will put a lot of wear on the non replacable SSD.

You could have a cronjob run something like find /home/user/.cache -type f -atime +30 -delete, which would find files that haven’t been accessed in the last 30 days and delete them. Make sure your home partition is not mounted with the noatime option though.
I’ve never seen any of my ~/.cache directories get more than a few GB either and I never bother to clean them.
I am curious what OP was doing that used that much space though. That’s certainly not typical.
I always shoot in raw+jpeg with the jpeg quality set to 100%. The raw files have a higher dynamic range and there is little or no processing done to them. The files are large, but storage space is cheap these days. The jpeg files are for convenience and if I don’t like the way they come out, I can process the raw file however I want and export it to whatever format is most suitable for what I’m using it for.
