happy mailing list membership reminder day

The paper writing.
Or even writing it up for my homepage sucks so much.

Dude's looking for capacitor whine

When Behringer runs out of repos to copy and paste on Émilie Gillet's Github page, a whole lot of dystopian Chinese factory town workers will be out of a job.

Farewell Shunsaku Tamiya: The Man Who Gave Us The Best Things To Build

Ham Radio Users Clash With Starlink Rival AST SpaceMobile Over Spectrum Use AST wants to use the 430 to 440MHz band for a satellite-to-phone service. Ham radio enthusiasts say the company's plan is vague and could interfere with their slim slice of spectrum.

How about recapping your stove?
Because I have done that.

Kester and whatever name Multicore is under now are fine.
I have used them over Chipquik myself.
As for flux, there is also MG Chemicals, which seems more available in some places as well.

For your entertainment!
Here is switching on and off an 800A breaker I got from ewaste.

It has an internal motor to wind the spring, but its not powered up, so the manual winder has to be used.

the Marathon alpha released recently and its environments are covered with assets lifted from poster designs i made in 2017.

IBM punch card laid in front of a lined notebook page. the contents are already described in the post.

so i wrote another program for the IBM 1401 computer this past week. i wrote what it does on the card, but can you figure out how it works? the program is

that last little character is special!

Mowerbot back after a night on the lawn.

Low leakage and low ripple?
We used some medical grade power supplies in things because those had the lowest noise of all the COTS power supplies we could get for the price we wanted to pay.

But the large transformer could be an attempt to meet the medical isolation requirements.
That's my guess.

Is it a Zener and not some TVS diode for ESD protection?

And no, it was not on the first try.

Here's the DUT.

Ya recon that's the UART TX pin?

Shiny waveguide multiplier with a WR-137 flange.
So maybe 5.76GHz target output with suitable Drive.
Currently best output was achieved on ~6GHz with 1.5GHz and 3GHz drive.

Yeah that seems to be the consensus.
1/4 and 1/3 of them have now been scrapped.
One even gave a "new" CR2032 and holder for it for my RB58vy 4m radio.
The previous one lasted only then years!

My first 122GHz band QSO.
VK3CV transceiver with UV-K5 with fagci spectrum as the IF radio.
QSO was with Michael, OH2AUE.
#122GHz #mmW #microwaves

yes

What probe are you using?
Some homebrew magnetic pickup?

Here's another angle of it in use.

Rate my PTT.

Privation Sensorielle, by Daniel Anonyme 13 track album

That we even considered sheltering such a wild slate of stories under D&W's patchy umbrella speaks to one of its great strengths and, to me, joys - it was less a comic, more a launchpad for whatever hare-brained thing tickled us in a given week, like releasing an entire album of in-character noise.

This WiSpry made one is commanded via the MIPI RFFE interface.
pSemi also makes some with normal, sane SPI interface.

I doubt Qcomm exposes that functionality via AT commands.
Especially when with a bad match it might be possible to make the PA distort and thus fail radiated emissions.
From what I gather cellular basebands often don't even do proper dynamic antenna tuning.
But instead use precalc'd values per freq

Picture shows seven rack mount devices. Three 2u Avaya G430's are piled on a chair with a helixal 1800Mhz antenna under it and a SmartStore box with a threephase plug in it. Four 4U or 5U Avaya G450's stand on their side next to it.

Okay so, one of the local radio clubs got these Avaya things.
Outside of them doing VOIP and that one dude reportedly has two controllers for them, I don't really know anything about them.

4x G450 and 3x G430
Is there anything useful one could do with these?

Or should we just part these out?

I wonder if this is why their search results have lately gotten significantly worse.

A dark evening snow scene featuring snow covered fields bordered baby hedges. An icy road crosses between them. A line of telephone poles extends into the distance, where a tall radio mast marked with red lights stands. At the base of the closest pole is a payphone with the receiver hanging by its cord. Footprints in the snow lead to and away from it.
