@DJSnM I need this in my C172...

[Andreas Mårtensson @jeppig]

Assembled the first v2 unit of the Metar-display.

Has "set" mode that lets you set ICAO-code, SSID/Pass, scrollspeed and brightness.

In 1960s, the Apollo missions gave people something to believe in. We could use that right now. And I think Artemis II is it.

After ski-coding with smoked ham and a cold beer... The best kind of coding.

built my own personal assistent device that runs OpenClaw.

I was curious what the smallest form factor could be that fits in my pocket so I wanted to use the Pi Zero W.

Works via Push to Talk->Transcribe->Sends to OpenClaw and streams the response back.

Headphones on. Laptop open. Ship something

A great example of what radical transparency can do for complex programs.
SLS may be the most expensive and delayed vehicle ever, but detailed, candid updates like this make it much easier to stay supportive.

As an update to my earlier post.

- The ICPS helium bottles are used to purge the engines, as well as for LH2 and LOX tank pressurization. The systems did work correctly during WDR1 and WDR2.

- Last evening, the team was unable to get helium flow through the vehicle. This occurred during a routine operation to repressurize the system.

- We observed a similar failure signature on Artemis I.

- The Artemis II vehicle is in a safe configuration, using ground ECS purge for the engines versus the onboard helium supply.

- Potential faults could include the final filter between the ground and flight vehicle, located on the umbilical, though this seems least likely based on the failure signature. It could also be a failed QD umbilical interface, where similar issues have been observed. It could also be a failed check valve onboard the vehicle, which would be consistent with Artemis I, though corrective actions were taken to minimize reoccurrence on Artemis II.

Regardless of the potential fault, accessing and remediating any of these issues can only be performed in the VAB.

As mentioned previously, we will begin preparations for rollback, and this will take the March launch window out of consideration.

I understand people are disappointed by this development. That disappointment is felt most by the team at NASA, who have been working tirelessly to prepare for this great endeavor. During the 1960s, when NASA achieved what most thought was impossible, and what has never been repeated since, there were many setbacks. One historic example is that Neil Armstrong spent less than 11 hours in space on Gemini 8 before his mission ended prematurely due to a technical issue. A little over three years later, he became the first man to walk on the Moon.

There are many differences between the 1960s and today, and expectations should rightfully be high after the time and expense invested in this program. I will say again, the President created Artemis as a program that will far surpass what America achieved during Apollo. We will return in the years ahead, we will build a Moon base, and undertake what should be continuous missions to and from the lunar environment. Where we begin with this architecture and flight rate is not where it will end.

Please expect a more extensive briefing later this week as we outline the path forward, not just for Artemis II, but for subsequent missions, to ensure NASA meets the President’s vision to return to the Moon and, this time, to stay.

The enclosure needs a redesign to avoid heat from the ESP8266 affecting the sensor readings...

@ComputerHistory To fill up an entire office space with these and have people happily clicking away like just another day at the office...

Yes, I might have an AliExpress addiction. No, I’m not prepared to do anything about it.

[Andreas Mårtensson @jeppig]

@NASAAdmin @Erdayastronaut @SciGuySpace The @NASAAdmin himself providing insight and clarification in the comments is so valuable.

[Andreas Mårtensson @jeppig]

I don't remember having to use the magnifying glass this much when i first learnt to solder 30 years ago... 🤔

[Andreas Mårtensson @jeppig]

Nice crisp day for flying...

[Andreas Mårtensson @jeppig]

First time using these knurled insert nuts.

[Andreas Mårtensson @jeppig]

Just one more ESP32… I promise

METAR display now has a "SET" mode that lets you change settings from your phone without flashing firmware.

@richardquest On the contrary, thank you sir for doing your part in putting a stop to this 🫡

@NASAAdmin @dpoddolphinpro @ej_sa Coffee and snacks are a critical, often underestimated part of every project budget.
