@tubetime Oh I'd love to see the inside of the 'platform adapter' - I assume that's an analogue computer?

@tubetime : Nice noise !

@tubetime The whole thing has to sit inside a temp. controlled "oven" like an old Sperry Univac mercury delay line memory.
`These components are placed within the Component Oven at 71 °C. Also the gyros and accelerometers are kept at 71 °C ± 1.1 °C. The ambient atmospheric temperature inside the platform is maintained at 51.7 °C by a set of heaters and a circulating fan, and a motor driven cooling air valve controlling the flow of pressurized air through the double walled platform cover.`

@tubetime Further down the article it mentions how the pilot would get the navigator setup before a flight. Switch would be set from Off to Standby.
`In this mode the platform and component oven are brought up to operating temperature; indicated by the "heat" light on the IN Control Panel, which takes several minutes depending on outside and system temperatures.`

@tubetime And apparently the drift on this thing was very usable over long distances.
`In November 1965 a LN-3 system was installed in a prepared Flying Tigers Boeing 707 (the Pole Cat) to conduct a pole to pole 51 hours flight, and compare its performance with other means of navigation. The quoted error at the South pole was 2 miles.`

@tubetime I need to build a balancing robot big enough to use this.....

@tubetime My father was an engineer for Litton from 1961 to 1994. He worked on analog INS all the way to ring laser gyros. Cool stuff. Early career was F-4's and A-6 intruders. Then F-14s and S-3s. Last was OV-1 Mohawk. I still have his copy of Bowditch's American Practical Navigator.

@carpetbomberz you can see the orange patch heaters on the center part of the gimbal

@tubetime TIL and painfully realized that the artificial horizon is also connected to this.
I always thought these worked way differently (most primitive way would be a ball suspended in liquid), but of course I failed to realize that the accelerations endured even in casual flight would probably make that attitude indicator so ridiculously inaccurate, one would be better off without one.
And it's also called a gyro horizon in english, TIL again. -

Reti 5G, UE: “In tre anni via ZTE e Huawei”
@informatica
“Insieme agli Stati membri, individueremo quali componenti specifiche della catena di fornitura ICT dei nostri settori critici richiederebbero misure di mitigazione mirate. Proponiamo una serie di possibili misure di riduzione del rischio, tra cui restrizioni per i fornitori ad alto rischio”.Così ha scritto Henna Virkkunen,

Esce al #cinema "La Grazia" di Paolo Sorrentino, film presentato all'82 Mostra di Venezia. Tra i vari riconoscimenti ha ricevuto il nostro Premio Brian per aver affrontato con profondità laica il tema del #finevita in Italia.👇 https://blog.uaar.it/2025/09/06/premio-brian-2025-la-grazia/

@anominominominous si, vedevo dalla mappa ieri che ancora la zona nord-orientale della Sicilia era messa male, non so la Calabria.

Postazione trobadorica pronta, direi.

@andre123 @marcoboh UE finanzia il debito americano e non investe a casa, siamo proprio scemi (capisco i guadagni ma se non pensi a lungo termine mai arrivi alla resa dei conti prima o poi, cioè oggi)

Vi ricordate di #ZioTibia?! 💀
Il narratore macabro de I Racconti della Cripta (1989-1996), che ci ha fatto venire i brividi con quella risata!
In Italia arrivò su Italia 1 nel 1991, diventando un culto assoluto per gli amanti dell’horror. E sapete chi ci ha recitato ? Arnold Schwarzenegger, Demi Moore, Brad Pitt e persino Michael J. Fox! 🎬Un mix di paura, ironia e star hollywoodiane che non si dimentica! @spettacoli@diggita.com @spettacoli

@andre123 @marcoboh un cambiamento c'è già, ma da un lato siamo vincolati dai nostri stessi interessi (mica possiamo togliere tutti i soldi dal debito pubblico americano, lo faremo ma piano piano), dall'altro per avviare e terminare un cambiamento strutturale ci vuole tempo, non si fa in un giorno
E il momento attuale richiede cambiamenti repentini
E siamo costretti a tentennare senza poter concentrare le forze e i nostri sforzi, che quindi andranno in gran parte a vuoto come un boxer tuonato
