The fact this cable is possible and exists is equal parts cursed and amazing.

Update: it sucks lol – check my reply below

@brunoph ohh I didn’t realize you could buy them now. I’ve got several I’ve made from old power bricks and those cheap PD trigger boards from Amazon.

@brunoph alas, that’s unfortunate. well you could chop the barrel off and wire it to one of these (get the one with terminal blocks mounted so no soldering). https://www.alexwhittemore.com/notes-on-usb-pd-triggers-and-zy12pdn-instructions/

Bought a TC-14EII 1.4x teleconverter for my telephoto lens, and Nikon lists the AF-S 105mm ƒ/2.8 macro lens as compatible but with "AF not possible", which made no sense since it's a very fast lens.

So I connected it to my Z6ii and… it worked fine! Fast AF too! Hmm… Maybe a recent firmware update fixed it?

So I tried on my 2006 F75 film camera and… it also worked!!

What the hell Nikon…

@brunoph maybe it just didn’t work with the era of DSLRs that had a separate phase detect array (pre-mirrorless)?

It's hard to pick favorites, as many of my photos turned out pretty good. So here's a few picked to give you an idea of how varied the show was tonight.

this photo was taken just moments after the previous one. the angle is almost identical, but now the columns are mostly green, with some faint red, purple, and blue also visible
the sky seen straight upwards. the aurora seems to pour down from the heavens like a cosmic shower. it spirals in a great mix of green, purple, red, yellow, and white. some of the sight is blocked by trees, giving it an immense sense of scale
now looking towards the bay again, the aurora seems to emanate from the corner of the frame, spreading outwards in a fan. there's a bright red column in the middles, and many more columns of green around it. they all reflect off the water

I’ve lost the plot on the “enshitification” discourse but surely NFC zippers are adjacent. https://ykkasia.com/touchlink-a-zipper-puller-with-built-in-nfc-chip/

Early morning adventure out to Travis AFB to catch NASA 926 departing after an overnight on its way back to Texas from a mission in Hawaii. Had never seen a WB-57 flying before. Not great pics since they used the more remote runway but still fun. Also US Navy E-6B departing before it (unrelated). @JetTip

fun afternoon at the Bay Model in Sausalito. the pumps weren’t running today so it was a bit more post-apocalyptic than intended. https://www.spn.usace.army.mil/Missions/Recreation/Bay-Model-Visitor-Center/The-Bay-Model-Journey/

Many photos on the signs at the Bay Model are credited to Robert Campbell, who seems to have been very active in aerial photography in the 90s and early 2000s. Great stuff. https://www.robertcampbellphotography.com/san_francisco.html

the internet has gotten very dumb but somehow I can still watch an hour on fixing test card generators from forty years ago so not all is lost. https://youtu.be/4XWZ4RnHk4g

went to my “want to go” map to add a pin for the original El Torito of bootable CD-ROM fame and realized I’ve already eaten there several times without realizing it. it appears to be a much better restaurant now.

A decade ago this week, I learned that they open the Trinity test site to the public twice a year and I was underemployed so convinced @mct to go on a roadtrip why not. The Trinity site was interesting but the real treat was stopping at the VLA the day before. I was just starting to dabble in signal processing and one of the tour guides was working on their FPGAs—I learned a lot. Also the weather was incredible. https://www.flickr.com/search/?user_id=80321933%40N00&sort=date-taken-desc&text=&view_all=1&min_taken_date=1396335600&max_taken_date=1397631599
