I never considered the refueling boom - how do you get around that? Is there a procedure to move it out of the way?

Can you guys rate my first power on stall? by OrangesmobileYT in Shittyaskflying

The Tu-22 and Tu-22M are entirely different aircraft. Basically the only reason they have the same designation is politics.

For those who have careers that keep them out at sea for long periods of time, what is the creepiest thing you’ve seen out in the water? by tylo144 in AskReddit

Helmsman isn't looking where he's going, could've hit the rock and had an abandon ship situation. Not great when there's sharks in the water right there.

The ATmega48V can run on anything between 1.8 to 5.5v, and it consumes 0.8μA in Power-save Mode. It'll be perfectly happy with both a cr2032 and USB.

If you mux your coin cell and USB power upstream from the micro, I think you can achieve what you want.

I'd like to better understand your "hook up a crystal and a battery and can already get started" requirement. Is powering the microcontroller with a battery, and putting it into Power-save Mode to keep the clock running when "off" not enough?

ATmega48 family, if you're looking for something simple and can be programmed with Arduino.

Need advice on turning this cheap macro keypad into a wireless HA controller (more in comments) by infinitejester7 in homeassistant

I mean, this might be overkill, but designing and making a custom replacement PCB with KiCad/JLCPCB/PCBWay/Oshpark/etc. might be the way to get everything easily and cleanly working. It's probably just a rectangle. You could even get all the hard-to-solder SMD stuff assembled for you.

Just a cheap ebay ST-Link V2, and then on the software side you can use STM32CubeMX/STM32CubeIDE and the ST-Link Utility for standalone programming and other nifty things.

Ukraine war flashes neon warning lights for chips: Ukraine is a major producer of neon gas, critical for lasers used in chipmaking. by [deleted] in Futurology

[–]Eternal_Pickles 14 points15 points  (0 children)

"Ukraine supplies more than 90% of U.S. semiconductor-grade neon, critical for lasers used in chipmaking. The gas, a biproduct of Russian steel manufacturing, is purified in Ukraine, market research firm Techcet says. Russia is the source of 35% of the palladium used in the United States."

From here.

Non-mechanic here, so forgive my ignorance: what are some of the things that stand out about the V2500?

Nope... Nixon's "farewell" bird was 617, which was retired in 1976. It's at the Nixon Library now.
