#Wss366 Buck #TimeTravelAuthors Hug

“I remember this man,” I said, pointing at Trollop. “He was a TV star and grifter. I have no memory of how he ends, so this must be from around the time I died. From here on out, it’s a futurerama. Maybe you’ll get to see #Buck Rogers. You said you wanted to see that kind of future.”

“Who?” Emily looked like she was going to laugh.

“Sorry, I thought you would know that one. He's an old science fiction character. At least he's old to me. He featured in serials...”

“Shush, listen,” Emily interrupted.

I heard a faint sound like, “Tekeli-li! Teke-li!” The flute-like music grew louder, raising the hair on the back of my neck.

Desperate, I grabbed Emily in an embrace that under other circumstances could have been mistaken for a #hug, saying, “We have to get out of here.”

“Take us somewhere else where we can learn about the rabbits!” we said together.

Buck Rogers:

"Chores?"
"I feed the pigs and Teenay feeds the chickens. Bello takes the sheep out. Mama and Sendi milk the cows. And Daddy and #Buck take care of the horses and get tack ready for the day's work."
"What can I do?"
"You get to help!" (2/2) #wss366 from Lady Cecelia's Knowledge, Part Four of Lady Cecelia's Journey

Okay Mastodon let's see if you can help.
I have this TPS560430 DC/DC buck which now has blown up twice on similar boards.

In both cases the failure occurred when plugging in to a live 24V 2A source. It appears the DC/DC has some kind of latch up and catches fire. Downstream of the buck is a TVS which is used for protecting some I/O ports, an STM32 and a few bits and pieces.

For a temporary workaround I've placed a 100R resistor between the 24V supply and the TPS560430, but I'm not sure of the cause and whether this resistor would help. It's also going to affect stability of the buck especially under load.

Anyone have an idea where I'm going wrong?

House Republicans are panicking about their shrinking majority after Rep. #Ken #Buck (R-Colo.) said he will #resign at the end of next week, stunning GOP leadership.
Why it matters: Republicans' razor-thin margins have created headaches throughout the 118th Congress
— empowering hardliners, causing embarrassing defeats on key votes, and even contributing to the ouster of House Speaker Kevin McCarthy (R-Calif.).

The intrigue: Members of Republican leadership said they were #blindsided by Buck's sudden announcement.
"I was surprised by Ken's announcement — I look forward to talking with him about that," House Speaker Mike Johnson (R-La.) told reporters.
House Majority Leader Steve Scalise (R-La.) said: "I haven't gotten to talk to him. He wasn't on the floor but I'm curious to see why he's leaving early."

By the numbers: Republicans will have 218 seats to Democrats' 213 after Buck leaves, meaning the
👉GOP can lose just two of their members on any given party-line vote.
The resignations of McCarthy and Rep. Bill Johnson (R-Ohio) — as well as the expulsion of Rep. George Santos (R-N.Y.) and the loss of his seat to Democrats — have led Republicans to this point.
A #special #election in April to replace Rep. Brian Higgins (D-N.Y.) will likely net Democrats another seat.
Republicans are then poised to win the May and June elections to replace McCarthy and Johnson, respectively.
Colorado Gov. Jared Polis said he intends to set the special election to fill Buck's seat for June 25.

What they're saying: "It lowers the margin and that creates an obvious challenge for leadership," Rep. Steve Womack (R-Ark.) told Axios of Buck's resignation.
"I am concerned about the majority," said Rep. Mike Kelly (R-Pa.), adding, "I just wish the rest of our party was."
House Rules Committee Chair Tom Cole (R-Okla.) said of Buck's decision: "Obviously, it makes the numbers that much tougher."

Reality check: House Republicans have🔹 dispensed with many party-line votes out of fear of right-wing defections.🔹
Major bills are now routinely being passed through a process known as "#suspension," which requires a two-thirds majority for votes to succeed.

Between the lines: What Buck's resignation means in practice is that "if it can go wrong, it probably will go wrong — at the worst time," Womack explained.
On any given vote, he said, Republicans could be hobbled by "absences, through travel or illness or family hardship or whatever."

Guten Morgen (or good morning😊) #fediverse! Heute mal wieder ein Foto, welches gleich zu 2 hashtags passt, nämlich sowohl zum #makromittwoch als auch zum kommenden #insektensamstag.

Der Moschusbock (Aromia moschata)
Dieser nach Moschus „duftende“ Bockkäfer ist der einzige Repräsentant der Gattung Aromia in Europa. Als typischer Vertreter der #Bockkäfer ist der #Moschusbock an der gestreckten Körperform (Länge 20-35 Millimeter) und den langen Fühlern gut zu erkennen. Die Körperfarbe variiert von hellgrün bis nahezu schwarz und weist einen typischen metallischen Glanz auf. Charakteristisch ist der #Moschusgeruch, den die Tiere über ein Sekret aus den Hinterbrustdrüsen absondern können.

The musk beetle (Aromia moschata)
This musk-scented longhorned beetle is the only specimen of the genus Aromia in Europe. As a typical representative of the #buck #beetles, the #muskbeetle can be easily recognized by its elongated body shape (length 20-35 millimetres) and long antennae. The body color varies from light green to almost black and has a typical metallic sheen. A characteristic feature is the #musky #odor, which the animals can excrete via a secretion from the rear mammary glands.

Here's another power project, it's actually a copy of something I posted a while back. It's another diode OR UPS, this time meant to power a Raspberry Pi (or something else that takes 5 volts).

I found some cheap adjustable #buck converters on Amazon. The idea is to step down 12 V nominal, either from another battery, a power supply, or perhaps a solar panel, to about 7 V or so - this is labeled Vbuck in the schematic. From there current can flow into the battery, a 6 V gel cell lead acid in this case, via D1 and Rch. It can also flow through D3 into the 7805 regulator, which puts out 5 volts. If the input power to the buck converter is taken away, power flows from the battery to the 7805 through D2.

It's dirt simple, and my intent is to keep the 6 volt battery floated. Basically, pick the float voltage you want (say 6.6 V), and add the diode drop to it. This is about what you set the output of the buck converter to. The resistor Rch is just there to limit the current in case the battery gets significantly discharged - once it hits the float voltage you want, very little current will flow. Pick a low end voltage, maybe 5.5 V, and set the resistor such that the voltage drop gives you the current you want: (7-0.4-5.5)/Rch

I just used a 3.9 ohm resistor since I had it. Don't forget to make sure it can take the power, but in my case it should be around a quarter of a watt (it's a 2 watt resistor). You can also bump the voltage up of the buck converter to get a little more current if you want some more granularity.

The key is to have a buck converter you can adjust. The diodes here are big for what I'm using them for, but I had a tube of them from past dumpster diving. You could probably come up with a better circuit, utilizing a specially-designed switching supply, but this is quick and dirty and should work.

I checked voltages tonight, but may get around to trying it with an actual Pi tomorrow.
