@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. -

@andre123 @marcoboh per adesso vedo Macron fare un passo avanti e la Meloni con tutto il suo governo fare due passi indietro 😆
Ma i dem americani (con eccezioni) sono come i dem italiani, anzi qualche sommovimento lo vedo là (vedi il sindaco di NYC), da noi....
E poi bho, gli italiani sono dei maga facsimile, pecorari con tutto rispetto per i pecorari, passano il tempo a guardare Affari tuoi perché gli piace il titolo della trasmissione...

Espressif Introduces the ESP32-E22 Wi-Fi 6E and Bluetooth Co-Processor
Espressif has unveiled its latest major chip in the form of the ESP32-E22. Officially referred to as a Radio Co-Processor (RCP), it’s intended to be used via its PCIe 2.1 or SDIO 3.0 host interface to provide wireless communications to an SoC or similar.
This wireless functionality includes full WiFi 6E functionality across all three bands, 160 MHz channel bandwidth and 2×2 MU-MIMO, making it quite a leap from the basic WiFi provided by e.g. the ESP32-S* and -C* series. There is also Bluetooth Classic and BLE 5.4 support, which is a relief for those who were missing Bluetooth Classic in all but the original ESP32 for e.g. A2DP sinks and sources.
The ESP32-E22 processing grunt is provided by two proprietary Espressif RISC-V CPU cores that can run at 500 MHz. At this point no details appear to be available about whether a low-power core is also present, nor any additional peripherals. Since the graphics on the Espressif PR article appear to be generic, machine-generated images – that switch the chip’s appearance from a BGA to an LQFP package at random – there’s little more that we can gather from there either.
Currently Espressif is making engineering samples available to interested parties after presumed vetting, which would indicate that any kind of public release will still be a while off. Whether this chip would make for an interesting stand-alone MCU or SoC along the lines of the -S3 or -P4 will remain a bit of a mystery for a bit longer.
Thanks to [Rogan] for the tip.

@gitanjali Tu hai capito perfettamente il senso dell'articolo, vedo. Ti aiuto: chi dazia, come sta facendo Trump, si spara nei piedi. Chi risponde, spesso si spara in testa. La dignità è sempre preferibile alla finanza, ma con crolli finanziari la dignità rischia di soffrire molto.

Cose prevedibili e previste. Non solo EV ma anche ibride e termiche. E accadono ovunque, non solo in un paese con una produzione di auto in via di estinzione.

@kristinHenry @talios yes, I'm waiting for the partner approval rating to settle before seeing whether we'll go in for episode 2 and more.

@francina1909 ma anche avere Pippo e Paperoga sarebbe meglio di questi al governo

@bluberrycookie che curiosità, in italiano.
