They say it is edible but the whole growing out of the sack grossed me out on this one so I passed.

… Yeah, that is understandable. Great find! And I like the picture of the gills a lot

Bonus birbs

Hey, sorry for the slow response. Feel free to appoint me as a mod until someone else wants to fully take over so that you don’t feel pressured to hold that spot for longer

Interesting… Good to hear!

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.

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.

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.

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! :)

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.

That’s awesome!! Are they in a terrarium or outside?

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.

Ok! done

Yes! This happens to be pretty good reception of an image, there are others which are not so great. Sometimes you have to tweak the settings, or make sure you’re using the correct decoding mode; there are quite a few of them. They have names like Martin and Scottie, among others.

Alright, I think this is one that I should first practice with an SDR. I already identified the signal at 14,230 KHz, but maybe the phone is not capturing the audio from the device with the quality required. Or it might be the decoding. This will be easier to test with the computer.

If–and I hope you’ll forgive me for an assumption here–you have a US mailing address, you could get your US amateur licenses fairly quickly and then operate under CEPT (once you have General or Amateur Extra) within certain Dutch jurisdictions. You do not need to be a US citizen, or even live here. You can conduct your entire exam via online zoom call. I did my Tech (first license in the US) from a beach on a tropical island with adequate WiFi during the pandemic, and then I did General and Amateur Extra upgrades a couple of years later in a different part of the world, each only weeks apart, also via zoom.

Thanks for the tip, I wish I was a in tropical island at the moment. I don’t have a US mailing address, although I some in my family and family friends do. However, the system here appears to be quite streamlined - register online, show up to the test center, answer 40 multiple choice questions - I will do some practice tests with the relevant Dutch terminology and give a try. There is no penalty for failing (other than test cost) and no limit to how many attempts I can do. My partner also wants to get one so that she can also transmit, otherwise she’d see me having all the fun.

I tried a few different training methods and I am liking this one: https://stendec.io/morse/koch.html

Ooh, is that what SSTV should look like? I tried capturing some earlier today using Radio 36, but I could not get a good image. I even trying capturing the image directly from the audio of YouTube videos, and I could only get the silhouette of the image that way. I’ll keep trying.

Alright then, I’ll do it then… The exam will combine two challenges in one for me because I’ll have to take it in Dutch, and my Dutch is still not amazing, haha

Oooh, you are right! I actually did not know I had that toggle available. Thank you 😅

I was just now looking through a few resources to learn morse code so this is very helpful! It is fortunately simpler than I thought - I was under the impression that the code mapped to full words, not individual letters/numbers, and so that it was essentially a different language. Memorizing the alphabet seems relatively straight forward to me now, but it probably takes a lot of time and effort to become proficient. I’ll give it a try.

It is indeed magical when one considers the minimum resources needed to transmit and receive CW over long distances. Of course digital modes are quite efficient and accessible now, but I don’t think most people can turn millisecond arrays of 0’s and 1’s into actual words without the help of some fancy device.

Thanks a lot for your kind words and recommendations!

As for Morse code, actually yesterday I watched a video that blew my mind, this one: https://www.youtube.com/watch?v=GvQ_UnePS7w

It is so cool. Even if no longer necessary, the way this operator communicates over Morse code is fascinating and I would really like to be able to do that some day. So, if I do get a license I am for sure going to at least try to learn the bare minimum to identify myself and say hello with this nice gadget 😄
