Teardowns Show Off Serious Satellite Hardware


22631757

As hackers, we’re always pulling stuff apart—sometimes just to see what it’s like inside. Most of us have seen the inside of a computer, television, and phone. These are all common items that we come into contact with every day. Fewer of us have dived inside real spacey satellite hardware, if only for the lack of opportunity. Some good gear has landed on [Don]’s desk over the years though, so he got to pulling it apart and peering inside.

[Don] starts us off with a gorgeous… box… of some sort from Hughes Aircraft. He believes it to be from their Space & Communications group, and it seems to have something to do with satellite communications work. Externally, he gleans that it takes power and data hookups and outputs RF to, something… but he’s not entirely sure. Inside, we get a look at the old 90s electronics — lots of through hole, lots of big chunky components, and plenty of gold plating. [Don] breaks down the circuitry into various chunks and tries to make sense of it, determining that it’s got some high frequency RF generators in the 20 to 40 GHz range.

Scroll through the rest of [Don]’s thread and you’ll find more gems. He pulls apart a microwave transmitter from Space Micro — a much newer unit built somewhere around 2008-2011. Then he dives into a mysterious I/O board from Broad Reach, and a very old Hughes travelling wave tube from the 1970s. The latter even has a loose link to the Ford Motor Company, believe it or not.

Even if you don’t know precisely what you’re looking at, it’s still supremely interesting stuff—and all very satellite-y. We’ve seen some other neat satellite gear pulled apart before, too. Meanwhile, if you’ve been doing your own neat teardowns, don’t hesitate to let us know!

spesso la persona ignorante scaccia l'informazione come una zanzara fastidiosa e cerca "informazione" che dia sicurezza. ama anche arrabbiarsi visceralmente nelle fake new che propongono ad arte il designato cattivo di turno e permette in modo divertente di metterlo alla gogna e così di sfogarsi. in tutto questo l'attenzione per la ricerca di informazione corretta e utile è marginale. non c'è ricerca distintiva dei segni distintivi della fake new, di ricerca di reazione emotiva, di ricerca del valore della fonte. se tale persona ha una fantasia specifica, la sub-cultura che ne nasce attorno è benvenuta, purché confermi. una sub-cultura è un insieme di credenze e valori relativi, attorno alla quale si crea aggregazione sociale e diffusa. un esempio sono le gang all'interno di città usa. ma anche una religione, una credenza, un "valore" possono alimentare e diventare una sotto-cultura. una sottocultura non è "tossica" solo se sussiste la consapevolezza che questa rappresenta solo una parte di qualcosa più ampio e di valore maggiore.

A Hacker’s Travel Guide To Europe


22627753

This summer, I was pleasantly surprised when a friend of mine from Chicago turned up at one of the hacker camps I attended. A few days of hanging out in the sun ensued, doing cool hacker camp stuff, drinking unusual beverages, and generally having fun. It strikes me as a shame that this is such a rare occurrence, and since Hackaday is an American organisation and I am in a sense writing from its European outpost, I should do what I can to encourage my other friends from the USA and other parts of the world to visit. So here I’m trying to write a hacker’s guide to visiting Europe, in the hope that I’ll see more of you at future camps and other events.

It’s Intimidating. But Don’t Worry.

Danish road sign: "Se efter tog", or according to Google Translate: "Look for trains".Yes. We’d find this intimidating, too. Bewitchedroutine, Public domain.
First of all, I know that it’s intimidating to travel to an unfamiliar place where the language and customs may be different. I’m from England, which sits on a small island in the North Atlantic, and believe it or not it’s intimidating for us to start traveling too. It involves leaving the safety of home and crossing the sea whether by flight, ferry, or tunnel, and that lies outside one’s regular comfort zone.

Americans live in a country that’s almost a continent in its own right, so you can satisfy your travel lust without leaving home. Thus of course the idea of landing in Germany or the Netherlands is intimidating. But transatlantic flights are surprisingly cheap in the scheme of international travel because of intense competition, so I’m here to reassure you that you can travel my continent ‘s hacker community without either feeling out of your depth, or breaking the bank.

What About The Language Barrier?


Let’s start with the language. I’m a British English speaker, je parle Francais, een beetje Nederlands, and ein bischien Deutsch. (Ed note: errors left intact for authenticity.) The fact is though, while it’s nice to try my halting Dutch to buy a portion of haring en uitjes, the truth is I rarely find myself completely lost in my travels through the hacker community on just my native language. It may annoy the French to call English a lingua franca, but if you’re an Anglophone you’ve lucked out in having the international glue language at your fingertips. It’s the default translation when traveling, in major cities you will usually find people who speak it when you need to. Meanwhile we’re lucky enough that there are few cities which don’t have some form of hackerspace, so you can usually find someone friendly with local knowledge if you need a bit of advice.

So It’s Not As Scary As You Think, But Why Come Here?

The SHA2017 sign against a blue sky with fluffy clouds.Different countries take it in turns to host the year’s largest hacker camp. This is SHA2017, in the Netherlands.
From here in Europe we look over the Atlantic at events like Def Con with some envy, but the fact is that Americans do things a little differently from us. Those events are expensive, while for us a summer hacker event is a community led affair in a field with camping thrown in. Some of the tickets are a few hundred dollars, but that’s it, no hotels, just camping in a field with five thousand other hackers.

Even better, the smaller events are cheaper, and often have much more charm as they aren’t so overwhelming. I can afford to do more than one, because they don’t cost an outrageous amount, and if I work out my timing I can even travel from one to the next without needing anywhere to stay over, instead helping with set-up and teardown. Add to that those hundreds of hackerspaces in cities only a relatively short distance apart, and there’s a lot to see.

Getting Around Needn’t Bankrupt You

Screenshot of the eurail app, Paris to CopenhagenGetting around with eurail is as simple as selecting your journey, and boarding the train.
One of the great holidays of the world remains the Great North American Road Trip. Grab a car with a couple of friends, and head out across the wide open spaces on the roads less traveled. Eat at Mom-n-Pop roadside diners in flyspeck towns, and enjoy what the continent has to offer under that endless sky. But while hire cars and gasoline may be cheap in the USA, long distance driving is tedious, so Americans prefer to fly.

Europe is different, hire cars are expensive, gasoline is eye-wateringly expensive, and while budget flights can be cheap, they really are a royal pain in the ass. Fortunately our continent is still cris-crossed by an extensive passenger rail network, and while individual tickets can be expensive there’s a very handy hack that makes them a great choice for a tourist. It’s called the eurail pass, originally designed for young people but now available for all ages, and it offers universal access for visitors to the whole continent’s rail network.

Taking a train from Paris to Copenhagen is simply a case of punching the journey into the app, and doing it with 180 mph high-speed trains instead of slower regional trains usually only takes a few Euros extra booking fee. If you’ve ever wondered how I write about events all over Europe for Hackaday I can reveal that there’s no diamond-encrusted expense account, instead I use the domestic European version of this pass. It’s that good.

Where To Stay

A hacker campsite against a dramatic cloudy skyBornHack is one of the smaller European hacker camps, offering a week in a Danish forest.
If you are coming over for a hacker camp, there’s your campsite and event all rolled into one, but outside the camps there are still some affordable options. Starting with camping, for us it’s not the backwoods facilities of a trailhead camping spot but in most cases a commercial camp site. For not a huge a mount of money you’ll get toilets and showers along with your pitch, and even a 230V CEE-form power hook-up if you’re prepared to pay extra.

I’ve written Hackaday articles in more than one camp site in my time. Then if you have a eurail pass it’s worth noting that Europe has a night train network. If it’s a conventional sit-up train you might not have the most comfortable night, but for the extra cost of a sleeper berth you can swallow up the journey in comfort and have the day to do more interesting stuff. Then as everywhere it’s easy to find a hotel, I tend to aim for non-tourist-destination train stops and find a two-star room for about 50 to 70 Euros when I need one. And after a few nights camping and night training, you will need one. Finally as you wander around our continent’s hackerspaces you may find the occasional offer of a sofa for the night, but remember that most European houses are tiny and the etiquette around staying over may be a little different. Only expect to stay for a while and use someone’s place as a base if they really know you.

Day To Day

Dutch haring met uitjes en zuur, salted raw herring with chopped onions and pickles. Trust me, it's rather good.Try the local fast food, you won’t regret it. C van der, CC BY 2.0.
It’s possible to exist in many European cities using small-denomination cash in whatever the local currency is, and shopping in ancient markets for exotic ingredients. It’s fun, even. But Europeans shop at the same shops and supermarkets as anyone else, and your Mastercard will work here too.

Look out for budget supermarkets, Aldi, Lidl, or Netto if you’re on a shoestring, and Primark if you’re in need of clothing. Meanwhile eating out can be expensive, and we don’t have a tradition of eating out for breakfast. We have McDonalds, Burger King, and KFC here just like anywhere else, but seek out the local fast food, it’s worth it.

European Hackerspaces


Wrapping it up, if you’re an American you may not be used to most hackerspaces only being a few tens of miles from each other. As a member of several European spaces it’s great to have international visitors drop by, so please, check out online when you go somewhere, find the space, and give them a shout. I have drunk Club-Mate and eaten a variety of delicacies while sitting on shabby sofas in the company of my peers continent-wide, and if you’re One of Us and looking to get to know a country there’s no better way.

So. The Hackaday Tourist Guide has spoken, are we going to see you at a European event next summer?

Hackaday Podcast Episode 293: The Power of POKE, Folding Butterflies, and the CRT Effect


22621254

This week on the Podcast, Hackaday’s Elliot Williams and Kristina Panos joined forces to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week.

First up in the news: we’ve extended the 2024 Supercon Add-On contest by a week! That’s right, whether you were held up by Chinese fall holidays or not, here’s your chance to get in on this action.

A square image with the Supercon 8 Add-On Contest art featuring six SAOs hanging from lanyards.We love to see the add-ons people make for the badge every year, so this time around we’re really embracing the standard. The best SAOs will get a production run and they’ll be in the swag bag at Hackaday Europe 2025.

What’s That Sound pretty much totally stumped Kristina once again, although she kind of earned a half shirt. Can you get it? Can you figure it out? Can you guess what’s making that sound? If you can, and your number comes up, you get a special Hackaday Podcast t-shirt.

Then it’s on to the hacks, beginning with what actually causes warping in 3D prints, and a really cool display we’d never heard of. Then we’ll discuss the power of POKE when it comes to live coding music on the Commodore64, and the allure of CRTs when it comes to vintage gaming. Finally, we talk Hackaday comments and take a look at a couple of keyboards.

Double-Slit Time Diffraction At Optical Frequencies


22619524

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows diffraction at optical frequencies by changing the reflectivity of a film of indium-tin-oxide (ITO), as demonstrated in an April 2024 paper (preprint) by [Romain Tirole] et al. as published in Nature Physics. The reflectivity of a 40 nm thick film of ITO deposited on a glass surface is altered with 225 femtosecond pulses from a 230.2 THz (1300 nm) laser, creating temporal ‘slits’.

The diffraction in this case occurs in the temporal domain, creating frequencies in the frequency spectrum when a separate laser applies a brief probing pulse. The effect of this can be seen most clearly in an interferogram (see excerpt at the right). Perhaps the most interesting finding during the experiment was how quickly and easily the ITO layer’s reflectivity could be altered. With ITO being a very commonly used composition material that provides properties such as electrical conductivity and optical transparency which are incredibly useful for windows, displays and touch panels.

Although practical applications for temporal diffraction in the optical or other domains aren’t immediately obvious, much like [Young]’s original experiment the implications are likely to be felt (much) later.

Cyber-Attacco a ESET: Realtà o Falsa Accusa? Potrebbe esserci dietro il gruppo Handala


ESET ha negato le accuse secondo cui i suoi sistemi sarebbero stati compromessi dopo che lo specialista della sicurezza Kevin Beaumont ha rivelato una campagna malevola che sembrava essere effettuata utilizzando l’infrastruttura ESET.

Secondo il blog di Beaumont, uno dei dipendenti dell’azienda israeliana è rimasto vittima del malware dopo aver aperto un collegamento in un’e-mail presumibilmente inviata dal team ESET Advanced Threat Defense in Israele. L’email ha superato con successo i controlli DKIM e SPF per il dominio ESET, ma Google Workspace l’ha contrassegnata come pericolosa.

L’attacco è stato registrato l’8 ottobre ed era mirato a specialisti della sicurezza informatica in Israele. Il file dannoso è stato distribuito attraverso i server di ESET, con i destinatari che venivano avvertiti che l’attacco era stato effettuato da un aggressore “sostenuto dallo Stato”. Le vittime sono state inoltre incoraggiate a prendere parte al programma ESET Unleashed, che in realtà non esiste come iniziativa separata, sebbene sia menzionato nel marchio dell’azienda.

Il ricercatore ha trovato diverse DLL ESET e un file setup.exe dannoso nel file scaricato. Beaumont ha descritto il programma come un falso virus ransomware che imita il lavoro del famoso malware Yanluowang. Beaumont ha inoltre notato che i file sui dispositivi non possono essere recuperati perché si tratta di un Viper .

Durante l’esecuzione, il malware ha contattato anche un’organizzazione legata all’Iron Swords War Day, dedicato alla memoria delle vittime dell’attacco del 7 ottobre 2023. I fatti suggeriscono il possibile coinvolgimento di hacktivisti.

ESET ha negato la versione di Beaumont sull’hacking dell’ufficio israeliano dell’azienda. L’azienda ha sottolineato che l’incidente ha colpito un’organizzazione partner in Israele e che la campagna dannosa è stata bloccata in 10 minuti. ESET ha assicurato di aver bloccato con successo la minaccia e che i clienti sono al sicuro. La società ha inoltre confermato che sta collaborando con il proprio partner alle indagini e continua a monitorare la situazione.

La fonte dell’attività dannosa non è stata ancora identificata, ma i metodi utilizzati nell’attacco sono simili alle tattiche del gruppo filo-palestinese Handala. I ricercatori di Trellix hanno precedentemente riferito che Handala sta utilizzando attivamente dei dropper per attaccare le organizzazioni israeliane, rilevando centinaia di incidenti nell’arco di diverse settimane nel mese di luglio.

Chatting comes to the ATmosphere with Picosky, X is unbanned in Brazil, and a significant group of Brazilians moved back, and a deeper dive into aviary.domains.


Last Week in the ATmosphere – Oct 24 week 3

Chatting comes to the ATmosphere with Picosky, X is unbanned in Brazil, and a significant group of Brazilians moved back, and a deeper dive into aviary.domains.

Picosky


Picosky is a new chatting service build on top of atproto. Picosky was created by Juliet, and started as an experiment with building an simple chatting app on atproto, originally limited to just 12 characters per message. It was a demonstration of making an AppView for chatting on atproto that utilises the existing infrastructure of the network: You log in with your Bluesky/atproto account, messages are stored on your PDS, and the PicoSky AppView listens to all the messages on the Relay and displays them. The direct connection of your Bluesky account made it a fun place for atproto hackers to hang out, which expanded the scope of Picosky quickly to a serious project.

Over the last week or so Picosky has undergone rapid changes by the developers Juliet and Elainya: you can log in with OAuth, the character limit got increased multiple times, now at 2048, you can edit and delete your posts, and UI updates where it is now a clear and minimalist proper chat UI.

The simple structure of Picosky, and the way that it integrates with the atproto infrastrucuture, makes Picosky an attractive place to further build on by other developers: one of the first Picosky-compatible projects to make it available via IRC. This is a separate AppView, that reads the same posts as the Picosky AppView does, and that can fully interact (federate) with each other. Other projects in the works are an iOS client or one for the terminal.

Meanwhile, the Lexicon structure (which determines the format of the messages) has had a major update the other day: there is now support for creating separate rooms on Picosky. Anyone can create rooms, and the owner of the room can set moderation to be based on a deny-list or an allow-list. The frontend has not been updated yet to take advantage of this however, but I’m sure we’ll get back to Picosky next week.

The News


It is now a week since X has been unbanned in Brazil, and a significant part of the Brazilian user base that joined Bluesky has gone back to X. Daily Active User count dropped by half, from 1.2M to 600k. This number was around 300k before the ban, indicating that a large number of Brazilians did stick around: Portuguese is still the most popular language of the platform; 45% of posts are in Portuguese, compared to 32% English posts. It shows that social networks are extremely sticky, and people have very high switching costs. In that context, Bluesky has done well with the number of Brazilian who stayed around after X became unbanned.

Bluesky is hiring, and they are looking for a Feed Algorithmics Engineer. The job is to “design and implement machine learning models to improve personalized content recommendations, spam detection, labeling, and more.” As the network grows, so do the challenges of providing algorithmic recommendations for feeds and spam detection.

Threads struggles with moderation on their platform, and Bluesky is seizing the opportunity by creating an account on Threads to promote the platform as an alternative on (and to) Threads.

Altmetric, which tracks online engagement with academic research, is looking for people that are willing to help with feedback sessions for their Bluesky attention tracking roll-out.

Bluesky has updated their app (v1.92), with some new features: you can now pin a post to your profile. There are also design improvements, including new font options. You can also now filter your searches by language.

TOKIMEKI, an alternative client for Bluesky, now supports showing your atproto-powered Linkat and WhiteWind profiles.

Threads struggles with moderation on their platform, and Bluesky is seizing the opportunity by creating an account on Threads to promote the platform as an alternative on (and to) Threads.

Frontpage, a link-aggregator platform build on atproto, is now open and available for everyone to use. The developers say that they’ll work on notifications first, and that decentralised and self-sovereign sub-communities are coming later.

For the protocol-people: what happens when there are clashing lexicon fields? Nick Gerakines publishes his thoughts on how the Lexicon system can evolve, with some additional thoughtsby Bluesky protocol engineer Bryan Newbold.

Deep dive: Aviary.domains


Aviary.domains is a new service that helps managing domains for Bluesky and the ATmosphere, that recently launched in early access. Aviary makes it easy for people who have a domain name to share that domain name with other people as their handle.

To place Aviary in a larger context, a short explanation: It helps to understand as the central offering of the ATmosphere being a single digital identity. When you first sign up for Bluesky, two things happen:

  • You join the ATmosphere, by creating a digital identity (a DID) that works with all other products that are build on atproto.
  • You log in with this newly created identity into Bluesky, and use Bluesky with this digital identity.

This digital identity, a DID (Decentralized IDentifier) is a unique string of letters and numbers that can never change, which is good for computers because it is unique, but very unpractical for humans to use. That’s why you have a handle, which corresponds behind the scenes with your DID. The idea of atproto is to use a website domain name as your handle. You can always change your handle to a different handle if you want, as long as you have a website domain you can use. Most people do not have their own website domain, so when you first join the ATmosphere and your DID gets created, Bluesky also gives you one of their sub domains you can use: yourname.bsky.social.

The goal for Bluesky is that people use their website domains as their handle, as it gives an easy way to verify ownership: the owner of the website is also the owner of the account. One problem however, is that many people do not have their own website domain. This is both an opportunity for Bluesky (which now sells domain names to people), but also still a challenge: a significant group of people are simply not interested in paying money for what amounts to a better user name. Even if you have your own website domain, having to change DNS settings is still a technical barrier that is too high for a large group of people.

This is the part where Aviary.domains comes it, as it tries to find an audience for people who have a domain name, that they want to share with their community. It has created a system where an owner of a domain name can invite other people to use a version of that domain as their handle on Bluesky. So as the owner of laurenshof.online, I can log in with Aviary, and generate a subdomain for, lets say my cat. Aviary generates a link that my cat can click; they log in on Aviary with Bluesky’s OAuth, type in their name, press accept, and their handle is now changed, without them having to change settings.

What makes this different from projects like swifties.social, which also hand out subdomains for people to use as handles on Bluesky, is that it does not require the final step, changing settings in the app. It also gives the owner of the domain control over each subdomain, with the ability to subtract subdomains as well. This makes Aviary more useful for people who want to have more control over who identifies with the domain, and can show they are part of the community.

self-hosted 3d printing app Manyfold joins the fediverse, and sub.club expands to longform blogging with write.as


Last Week in Fediverse – ep 88

A quieter news week: self-hosted 3d printing app Manyfold joins the fediverse, and write.as now offers paid subscriptions for fediverse accounts with sub.club.

The News


Manyfold is a self-hosted open source web app for organising and managing your collection of 3d files, and in particularly 3d printing. With their latest update, Manyfold has now joined the fediverse by adding ActivityPub support. With the new integration, you can now follow a Manyfold creator from your fediverse account of choice, and get notified when the Manyfold account uploads a new 3d file. New Manyfold uploads appear as short posts with a link in the rest of the fediverse. To demonstrate, here is the Manyfold account from the creator Floppy as visible from Mastodon, and here is the profile on their Manyfold instance itself. The Manyfold server also has a button to follow the account on the fediverse.
Manyfold implementing ActivityPub support is an illustration of how ActivityPub can be viewed as a form of ‘Social RSS’: it allows you to follow any Actor for updates, and adds social features (sharing/liking to it).

Sub.club is a service that lets people create paid subscription feeds on the fediverse. The service recently launched with the ability to monetise Mastodon feeds, and has now expanded to also include long-form writing, by collaborating with write.as. Write.as is the flagship instance of fediverse blogging software WriteFreely. With this update, blogs on write.as can now set on a a per-blog basis if a blog is a premium blog, and where the cut-off is. People who follow the blog from a fediverse account will see an option to subscribe and view the full post; this post by the sub.club account shows how a premium blog will look like from various perspectives. Adding sub.club to a write.as blog is as simple as following this three-minute PeerTube video.
