A Cordoba Traditional stage guitar on a stool in the lab. Shape of a classical guitar with cutout but much thinner. Instead of a big, round resonant hole, it has three small ones, the size of a big thumb in the body part above the ~18th fret. It was on sale - for a rrrealy rrealy good price; only bc someone returned it. Brand new. Thanks, hehe.

Workbench with some electronics, tools, soldering irons/tweezers. In the middle, two Weller desktop solder fume extractors on top of each other. Only one does nothing. They suck at sucking and filtering. Not recommended.

New office soldering rules in place.
Double lol.

Post from Robert F. Kennedy: „Reports coming out of Germany show a government sidelining patient autonomy and limiting people's abilities to act on their own convictions when they face medical decisions. That is why Friday, I sent a letter to Germany's Federal Minister of Health, Nina Workin. In my letter, …“ Link to a video, talking bs for some minutes. Lol.

Dear United States Secretary of Death and Undertaking Services,

Lol.

Best,

Screenshot of the mobile app, a rainbow colored circle and some numbers in the middle: 1.72 kWh, 77%.

Same setup a previous post, but now with a second, larger power supply under the first one. Also delivering 100W.

One of the batteries immediately jumped to 75%. Tempted to start the inverter and achieve perpetual energy.

The back of two batteries with some cables on the left and a lab power supply with red LED display on the right, delivering 100W at 33V.

That’s not the way it’s supposed to work, lol. Now emergency-charging four solar batteries to save them. Two limiters working against each other, but I found a setting that doesn’t freak out the power supply.

Small ESP32 board with a soldered-on wire as an antenna. One end goes straight up, the other end forms a (270°) 3/4 circle and is soldered to the on-board SMD antenna chip. Photo, Peter Neufeld (c).

Simple 6dB+ antenna gain mod for small ESP32 boards. Nice.

Old and dirty of an old 100W Osram lamp in my hand. Found it in the basement. Unboxed :)

Screenshot of a „403 Forbidden - Apple“ page when I try to access the support forum. My user name is „.DS_Store“. Only used it one or two times, so no loss, but it‘s still half there and still not usable. Some manual address field changes made it possible to post something, but there‘s no way to view the post or any of the possibly incoming replies, lol.

Apparently, it was a bad idea to put a dot in the Apple support forum’s username when it was still allowed.

Bild seiner Listen, auf denen ich jetzt stehe. „Transphobe MAGA-Nazis, Ableisten, Kinderfresser, Antisemiten“. Nee, ich glaube, diesmal geht’s mir zu weit.

Trotzdem kein Grund die Scheiße zu verteilen. Blocke die Verteiler von Faschowerbung grundsätzlich. Aber dafür hat der Hustenmann ja seine Listen.

A Sony Playstation 1 was transformed into a four string bass guitar. The pickup and the bridge are mounted on the lid. The two big power and lid open buttons were turned into potentiometers. The left controller port is used as the instrument cable. Lol. Source Reddit: https://www.reddit.com/r/playstation/comments/1ob0wae/i_built_a_playstation_guitar/#lightbox

Finally, no more output jack issues.

Close up around the ~12th fret. Ugly inlays if whatever wild Christmas theme thus might be. Looks like a wet forest floor after summer.

Grundgütiger. A Christmas tree on the back of the guitar. A lot of ugly shapes in green and a bit of orange. I have (literally) no words for this lol.

Wtf is this??
The Martin steel-string “ugliest Christmas presents” edition?
For - lol what, €400k?
Hahaha…

MHO98 oscilloscope on top of a Rohde & Schwarz SMY 02 signal generator, tuned to 1.155GHz.

Same, but 2 channels; f=810MHz

3/4 channel BW 270MHz

3 channels and it displays an super high LF alias at 960MHz. 0 at 1GHz then the scope just shows f-1GHz. 80MHz instead of 1.08GHz et.al.

3dB BW is ~1.15GHz for one and ~810MHz for two channels activated, but this thing completely freaks out with three or more channels turned on. Full of aliases (even beyond 1.5GHz :) Maybe no CPU power left for filtering, hehe. But it’s actually nonsense to test this; signalpeeping a toy scope, lol.

MHO98 oscilloscope on a desk, displaying rising and falling edge of a DUT, soldered onto a bare PCB which is directly plugged into the scope’s BNC connector. A 9V battery is also connected dangl

Honestly, none of the advanced features, options, or triggers are really working on this MHO98 thingy, hehe. I only grabbed it for the form factor and the easy transformerless galvanic isolation. Bandwidth and signal integrity seem okay, though.

If I’m understanding this correctly, X is owned by a white nationalist who pays poor people of color in developing countries to pretend to be working class white Americans to scare other white Americans into being afraid poor people of color from developing countries are going to ruin America?

Meine Güte, was zum Fork bin ich da wieder lesend. Keine Ahnung mehr, wie man damit noch umgehen soll.

“All in” and BW unlocked Rohde & Schwarz MXO 3 oscilloscope on a desk. It has “LOL =)” written on the touch display.

Looks like we have a winner: The new R&S MXO 3. Keysight was a clear disappointment — and we’ve used Agilent/HP gear for decades. Rigol and Siglent … meh, lol. LeCroy still can’t get peak detection right. Tek, nah. Looks like mom’s old transistor radio, hehe.

Tiny black Rigol oscilloscope on a desk. There‘s a long stripe of blue tape attached to it on the back, so it cannot ti over.

Ended up taping the Rigol scope to the desk so it wouldn’t do a frontflip every time I touched the active probe.

A just-unboxed Rigol MHO98, a limited oscilloscope with quite some bandwidth and features, on top of the opened packidge

Oscilloscope weeks, as it seems.

A white Rigol oscilloscope on a desk, near some other scopes. It’s displaying Rigol very well. Perfect.

We’ve got a Rigol demo unit here as well.
So far, its only real activity is displaying ‘Rigol’ and generating hot air. Maybe it’s busy counting bits in its massive memory, or just contemplating existence and entropy.

Keysight HD3 scopein action on a desk. Ugly, cheap looking dark grey plastic front (looks better here than it’s actually is).

Photo of the rear digital channels connector. Just the old 40(?) pin header.

New Keysight oscilloscope. Now with digital channels on the back. No option to move them up/down on screen. Device not nearly as responsive as the old ones; everything’s lagging, ugh. And I absolutely dislike this new touchscreen trend. Why can’t I just have a button for the trigger menu goddamnit.

GaN transistor and resistor side by side. The transistor is upside down, the pins, like a BGA are pre soldered, but form stripes. Four large ones, across the smaller dim of the package, and one with 3/4 and a tiny ball for the gate in the lowest row.

A macro shot of the same view. The GaN is a bit smaller than the 1206 R, appr. 2.5 x 1.5 mm.
