Ask Electronics@discuss.tchncs.de•Lenovo USB-C PSU for laptops powers a Rasberry Pi, but cannot simply charge bicycle lights. WTF?English
2·26 days agoThey are actually headlights. The kind that strap to your head, which I happen to use for cycling. I suppose they were intended for joggers. I don’t know the makes but it’s two different manufactures, likely some cheap chinese stuff. One is an LED strip across the forehead with a side beam, 7 or so different functions with different colors and intensities. The other has selectable red, white, or yellow colors, blinking or solid.

1·28 days agoThe seller had a few of these same radios, new in box, but all missing the chargers. My thought was either the seller sold them separately or the chargers were stolen and so whatever retail store had them could not sell them and they ended up on the street market. But after seeing that the OEM chargers are strictly 9v, they seem worthless without the radio. Unless it’s just a shitty label. Maybe the OEM charger is proper USB PD, but they only wrote 9v on the label. I can only speculate.
The universal charger I have could also be dodgy. It was from a 2nd-hand shop. But afaik it’s fine.
Since I don’t have the OEM charger, I cannot see how it is marked. I just recall it was only marked 9v.
(edit) it’s also possible that the OEM chargers are poor quality and have short lives… maybe the retailer opened boxes just to replace broken chargers for customers under warranty, which would also result in radios without chargers.

2·28 days agoDead battery was my 1st theory, but it’s questionable. I fiddled with a healthy demo unit (same model) at the store. The battery ran out of juice and the machine shut down. I plugged it in and hit the power button and it instantly turned on. So it can apparently run directly off the USB-C as the battery charges (and the manual says as much). But the one I have never powers on, even when connected to power.

2·28 days agoUSB-C chargers won’t work in this case, as they only output voltage, if they detect a device.
Note that the first 2 times I attached a universal USB-C charger to the radio, it gave a charging animation (though after ~30-45 min wait). So I am struggling to work out how that happened. Did the charger give up after waiting a long time and say “fuck it, will give some arbitrary power”?
You need a USB-A charger with a A-to-C-cable.
My universal charger has both USB-A and USB-C ports. I tried the USB-C port first (thus usb-c→usb-c). Then at one point I tried usb-a→usb-c. I was expecting usb-A to behave the same because the charger specifies the same range of voltages for both ports. The only difference is the max current is a little higher on the usb-c.
evenwicht ( evenwicht@lemmy.sdf.org ) OPtoUS Law (local/state/federal) ⚖@lemmy.sdf.org•When the attorney general ignores your complaint
2·1 month agoA lawyer once told me there are a few left-leaning AGs who genuinely take the consumer protection role seriously. He named off a few states where he said you can expect decent treatment of compaints. Then he said a lot of AGs have no interest in the job at all. That they are just looking to climb the ladder and get a CV that enables them to run for governor. I think I have been quite unlucky with the states that are relevant to where I get burnt as a consumer. Though I don’t suppose that’s chance. The shittiest corporations are likely to select right-leaning anti-consumer states for their HQ.

2·2 months agoStupid you. That’s not how economics works. If a more expensive seat boosts airline profits, then they would simply already increase prices to begin with. They don’t need our permission. They can charge $1 million for a seat, if they want. But they will have a hard time selling the seat if it’s not going beyond the atmosphere.
Bit of econ 101 for you: If McDonalds spontaneously doubles the cost of a big mac out of the pure blue, they will more than double their profit on each burger. But they will sell substantially fewer, causing profits to drop. The market determines what price is optimum for profit.

1·2 months agoGraphene is Android. Why would a bank’s app not work? @TheHobbyist@lemmy.zip suggests that some banks proactively detect and block Graphene, while other banks’ apps simply accidentally fail on Graphene. Is accidental incompatibility really a notable issue on Graphene?

retrocomputing@lemmy.sdf.org•What was the Windows 3.0/1 graphical alternative that also ran on DOS?
2·2 months agoNo, I figured if I could recall the name I could get a nostalgic fix by searching it. I found this:
https://en.wikipedia.org/wiki/DESQview
I recall DESQview was much lighter weight and better performing than Windows, but had limitations. I did not recall that the windows were text only within, but that’s starting to fill some holes in my memory.

retrocomputing@lemmy.sdf.org•“Can my 2001 SPARC server host a website in 2026?” A: yes (if Cloudflare is okay.. yikes)
2·2 months agoOriginally ZFS could not be a boot disk because of the license issue. There was some other important feature that was denied to linux users, originally (forgot what it was). Apparently the booting restriction was eventually overcome. I don’t really grasp how the licensing changed that made booting possible.
Conceptually ZFS was relatively superior to all other filesystems. If it’s fully liberated, I don’t get why it is not more popular. I might expect it to be a default of sorts when installing Debian.

4·2 months agoI have one as well, mothballed, which is why the article caught my attention. Then I saw all the mention of Cloudflare and thought: oh fuck, so it needs a wheelchair with a mouth joystick, in effect.
What originally attracted me was running a full-blown ZFS, which was too license encumbered to be fully featured in linux or bsd, IIRC. I never got around to doing much with it. And now I wonder if ZFS is finally fully liberated on a FOSS platform.



Indeed it is rampant. Searching for “tor” is also a mess. Anything under 4 chars, generally, because UIs are now designed to assume normies cannot handle special syntax chars, like
\wor\<to mark word delimiters. But then Lemmy fails to give a higher rank to whole word matches. So it’s designed for people who struggle with tech /by/ people to struggle with tech.
