US long-range B-2 stealth bombers target underground bunkers of Yemen's Houthi rebels in c/[email protected]

It is, but thats an important detail about the capability of the B-2 that can be lost without pointing out.

These flew from US mainland into Yemen and bombed protected / hidden sites THEN flew back home.

The US gave warning of the attack and likely all the governments in the area saw were birds on their radar screens.

The B-2 was a great choice to deliver a quit messing with commerce message

Cheap E-Bikes seem more easy if you are willing to get into the wiring. A lot of them use very similar parts in terms of Hub Motor, Controller, Battery

I learned about these neat USB boards. I think I will use one in 9V mode for the Atari 7800 as an alternative means of powering it. It might fit in one of the existing cutouts. in c/[email protected]

I was curious myself so I looked up the data sheet fro the chip... I need this board in my life

I don't understand the reference between VBUS and VDD. Is anyone willing to explain how the risk of putting direct PSU voltage into the output device is avoided?

This is great. Even just soldering on a barrel jack and shrink tubing the whole thing would be a massive improvement.

All the old Power Supplies from the 90s and earlier made power really inefficiently and their failure modes can be... bad

Putting a GOOD USB-C charger onto these old systems is an elegant solution!

While funny... I think you underestimate how big the battery in a Tesla is and also how little power the computer would pull.

THAT said... I wonder if there is a drive somewhere that could be filled doing that?

Dialed in latency reduction + RF Blargg and I have the movie in the background

Bliss man...

Hey man, I had bit of time in between /s

Thanks for the recommendation... I am sucking but never noticed this game even in spite of a time when my friend and I were playing all the retro batman games we could find in like 08.

I suck at this one but thats to be expecting I am a Lemmy user after all.

Think your mom will let me use your Nintendo when we finish tonight? /s

I am going to check this out. I always preferred NES Batman and SNES Adventures of Batman and Robin myself

Have you ever committed mistakes while setting up your homelab? in c/[email protected]

[–] [email protected] 19 points 1 month ago (1 children)

All the time. Why have a home lab if you aren’t going to fuck things up? :)

Better it happens in the home lab than at work!!

Nah, the investors don't see it as a benefit to your growth to pay people you don't have to

How much current can I safely pull from an ESP8266? in c/[email protected]

[–] [email protected] 10 points 1 month ago* (last edited 1 month ago)

5V will be pulled directly from 5V supply

The chip you are concerned about getting warm I believe is your 3.3V regulator.

I would ensure your transistor has some resistors to ensure you are not drawing more current than required from the 3.3V supply

If that is all good then I will remind you of a few things

The board you have is a clone (I use them... but they can be dubious)
The ESP8266 requires a certain amount of current to run which will cause the chip in question to generate heat all on its own
The chip in question appears to be an LDO which will mean going from 5v to 3.3v is done by turning the excess voltage into heat.
