Sorry, I am in the process of moving and have not been able to keep a close eye, and the disk filled up. I have increased the disk size now, but I see some errors with the images. I need to sleep now but in the morning if it is not fixed I’ll figure out what is happening.

Science@mander.xyz•Why this $10 spectrometer chip could bring real-time chemical sensing to wearables
1·1 个月前Yes, there is a lot of potential. There are micro-spectrometers available covering this range, like the MEMS-FPI type spectrometer or the multi-pixel arrays with filters (example: https://www.mantispectra.com/products). But this new kind of detector seems to come with higher resolution, faster readout than the MEMS-FPI, and more sensitivity. It is quite exciting, I’m curious to see if they commercialize it soon.

Science@mander.xyz•Why this $10 spectrometer chip could bring real-time chemical sensing to wearables
2·1 个月前I am not 100% sure, but I think that the designer bears the cost of the wafer yield.
The PDK is specific to the manufacturer, and I imagine that the risk associated with specific features is known and the yield range can be estimated. A design with more and riskier the features would lower the expected yield, and it makes sense that this risk gets passed onto the designer. The contract may have some protections for the case when the yield is significantly lower than expected because of the manufacturer’s fault. Just a guess though, it would be great if someone with real experience can answer.

3·1 个月前Very cool!
I also like that they included a device cost analysis. I think they used some aggressively optimistic assumptions (100% yield from the wafer) and large-volume procurement prices that I am skeptical of, but if true it is valuable info.

Thanks!
The way submitters didn’t played by the rules
It is not that the submitters did not play by the rules. The ‘rules’ of the instance set the scope of the kind of communities that belong here, but I would not expect users from other instances to be aware of these rules. So, it was a mistake on my end not on any poster’s. It would have been better to react sooner, but better now than later.
There are ways this community could have been both science
From the name my impression was that the community was about more aligned with futuristic sci-fi, which would be a bit on the edge of the scope but acceptable.

You can have a look at some communities that often have content where science intersects politics:
https://mander.xyz/c/academia https://mander.xyz/c/earthscience https://mander.xyz/c/publichealth
Minimizing politics does not strictly mean being extreme about enforcing the no-politics rule. Posts that are about the interaction between politics and science generally contain enough overlap with science that it is acceptable. But that is not the case in this community, it is mostly general topics and politics.
Haha, thanks but no worries, the wound will heal 😁
The instance has had this policy for over 4 years. The sidebar reads:
The main focus of this instance is the natural sciences, and the scope encompasses all of the STEM fields.
Please keep politics to a minimum. When science is the focus, intersection with politics may be tolerated as long as the discussion is constructive and science remains the focus. As a general rule, political content posted directly to the instance’s local communities is discouraged and may be removed. You can of course engage in political discussions in non-local communities.
The goal when creating this instance was to a place to discuss about scientific discoveries, post pictures of nature, and have a set of communities for this while avoiding polarizing content. If someone wants to discuss politics they can click on ‘All’ and go right to it. The scope is explicitly anti-politics because I do not want to moderate a politically charged or polarizing environment, and I know that many people with interests like mine will also appreciate such a space existing because they see enough pictures of Donald Trump and polarizing discussions elsewhere.
y’all are a science community and science is being hunted down and destroyed systematically and your response is to try to become less political?
I do not disagree with you broadly, and that is to an extent why I use common sense and do not enforce the “no politics” rule religiously. There is quite a bit politics that gets through. Although I do prefer to offer users of this instance a politics free experience, if no one complains I usually let it go.
In this case: I have noticed posts in the front page that have nothing to do with science lately, and they came from this specific community. I then saw some US politics characters attached to articles that had nothing to do with science. I looked through the community and most of it is off-topic, so it makes more sense to lock the community.
I’m sorry this upsets you, I should have removed the community as soon as it was created, but I did not realize what it was.
Oooh, you are right! I actually did not know I had that toggle available. Thank you 😅
This is a general chat community for the instance. From my side (admin) I would draw the line at being mean, polarizing for no good reason, or dangerous. The community creator (@fossilesque) would decide how to handle more specific moderation points, but I don’t see an issue with chatting about science.
That said, I also created a community that is more specifically about general thoughts about science without needing to worry about ‘quality’: https://mander.xyz/c/thought_forge

I could see the credits for “Everything’s Gonna Be Alright” in Deezer, but I am not sure about how exactly Deezer determines this: https://www.deezer.com/us/album/951602381
I would make use of a VPS to serve a directory with the files using Nginx. The VPS is ~$5 /month. You can share the ip or buy a domain name for ~$10/year. If you are not opposed to vibe-coding, you can probably generate the Nginx + HTML config to play through the songs without having to click them individually with little effort.
