  1. I've just tested the principle of processing using Controlled-Envelope Single-Sideband modulation (CESSB) in and it is beyond beautiful.

    It uses a two stage process of clipping and peak stretching that combined can reduce the effects of over modulation typically introduced by

    Even extremely overmodulated input signals (25x) still produce clean audio indistinguishable from the original source signal.

  2. OK all my #electronics / #PCB fab #FediFrens 👋 I need [1] to get a custom #keypad designed & fabbed and I’m starting from a low low base of “sure I’ve put built plenty of electronics kits & learned a bit of electronics theory but mostly a long time ago & I haven’t designed anything myself”… 🙃

    so what’s the best way to get started? 🤔

    I found a couple of places that do custom #keyboards & have online key[board|pad] design tools, which seems about right. I don’t actually want to become an expert in custom PCB / #keyboard design, PCB fabbing, or managing Shenzhen supply chains – I just want to get this one thing made [2] and am happy [3] to exchange money for goods & services (within reason) to get it done

    I’ve already looked at just using a gaming keypad to do the thing but I really want to integrate the keypad into the other thing to get it to where I want it to be…
     
     
    OK, there’s no need to be coy I guess – I want to put a “real” keypad into my 1:1 #3Dprinted #Apollo #DSKY (WIP pic below)

    what’s my optimal pathway to getting this to exist? I imagine that other DSKY nerds may want one once it exists, so the ability to turn it into a limited run after the initial prototypes are done would be a bonus

    pls #boost4reach 🙏

  4. @tedu

    Yup. And some time ago too, I might add. The ability to take what works so well and complicate it to the point of absurdity never ceases to amaze.

    #Margaret_Hamilton put two men on the moon with 4K of memory. 8K if you're counting the additional RAM on the Columbia's #AGC.

    Well if you ever figure out how to lookup your NIC-HANDLE, as they're officially called (or rather, were), I'm BT-74 👋🤠

    Yeah, that goes back to the days of "Direct Assignment" when #SRI also operated under the auspices of NIC.DDN.MIL.

    Welcome to the club of unhappilly disenfranchised #NIC_handles 😥

  6. AGC или как перестать подстраивать громкость вручную

    Многие наверняка сталкивались с проблемой: смотришь по ТВ спокойный фильм, который прерывается резкой и громкой рекламой; или, например, при общении по ВКС всех собеседников слышно нормально, но у кого-нибудь одного микрофон будет шуметь так, будто он в данный момент находится рядом с двигателем самолета, готовящегося взлетать. Конечно, всегда можно подрегулировать громкость динамиков, но всегда ли это удобно и возможно?

  8. Wie viel Rechenpower braucht man für die Reise zum Mond? 🌙

    Gerade habe ich Frank O’Briens "The Apollo Guidance Computer“ beendet, und es ist eine Lektion in Demut. In den 60ern schufen Ingenieure mit den damaligen Mitteln ein System, dessen Architektur in Sachen Zuverlässigkeit bis heute Massstäbe setzt. Es zeigt: Wahrer Fortschritt liegt nicht in Gigahertz, sondern in technischer Klarheit.

    👉 Empfehlenswert für alle Technik-Begeisterten!

  9. Starting into a long day of travelling. The first bit: #Tarascon to #Marseille on board an #SNCF 🇫🇷 Class #Z27500 #lio #Occitanie #AGC unit. We are passing the #Crau plain before getting a glimpse of the #Mediterranean, shortly before reaching our terminus station.
    Good morning!

  13. Small persistent humid forest clearings drive tropical forest biomass losses

    "Tropical forests store about half of the global forest above ground carbon (AGC), yet extensive areas are affected by disturbances, such as deforestation from agricultural expansion and degradation from fires, selective logging, and edge effects...Findings highlight the disproportionate impact of small clearings on tropical carbon losses, suggesting the need to curb land-use changes and protect young and recovering forests."

  14. @vampiress I have a full-size #DSKY case 3D print already (for my #AGC display at the CBR vintage computer expo) & am aiming to have all the electronics done for the next one – if you want one let me know & I’ll just double the parts order for the stuff I can’t get printed 💁‍♀️

    (I also still have a few spare super-cute mini-DSKYs left, let me know if you want one & we’ll make it happen 🙃)

  18. @oysta I had a standee of #MargaretHamilton made for this year’s Canberra Vintage Computer Exhibition as part of my display on the #Apollo Guidance Computer, you’re welcome to borrow it to take on a flight to the US… 🤪
