C911 and other beads on that rail aren't (or soon won't be) good.

That and at least 2 dozen other bloody tants.

That half dozen are difficult to find on the boards and even scattered across several schematics, and are 15V on a 13V rail.

The main PSU is easy by comparison!

Blue is good.

Harley indeed goes nuts over laser pointers.

So does daughter's dog, for the same reasons.

Satellites are well tracked as is space junk. Commercial airliners also usually fly on predictable paths. Military aircraft are a different, but much rarer problem. It can't be all that difficult to manage time on the telescope to accommodate these things. Anyway, large numbers of satellites have b...

Exposure take 30s, which is relatively fast: https://rubinobservatory.org/explore/how-rubin-works/numbers . Nonetheless there will be trails, of course. "Time on telescope" is a scarce resource, so I imagine people will be reluctant to take the same picture multiple times. But what do I k...

I'm having difficulty understanding how you can find/select the interesting objects to examine. So many pixels, and interesting objects are often only a few pixels in size. Ditto how starlink trails are removed. To partially answer my own questions: https://skyviewer.app/explorer If you take the gu...

Remove starlink trails: I'd say, take some pictures shortly after, combine them and remove the starlink patterns. Perhaps a similar approach would work for finding interesting objects.

Wearable item. With the exception of Superman (who is famously sartorially confused), walking down a street wearing only pants can be grounds for being arrested. The parks will be full of semi-naked Poms working on their melanoma! Heatwave for the Poms seem now sent to the Yanks in NY where 34C is ...

it has been 29C here, 33C near London, looks like bits of France hit 38C. Definitely pants[1] and beer weather. RH is 50-60% so relatively tolerable. No aircon, unless you count an electric fan. [1] UK meaning, of course. What is the UK meaning of "pants"? Pants as in a wearable item or p...

Like who ever thought that wasn't gunna happen ? Will T'rump and his BFF Putin fall out? Will T'rump notice that Putin is stringing him along? What happens then? Does that mean Putin has a deadline for reconnecting Kaliningrad to mainland Russia at the Suwałki gap, or as some have suggested, restor...

Hasn't it already started, in the same way WW3 has started? Yes, it appears that Elon and Donald have had a falling out. Like who ever thought that wasn't gunna happen ?

Although one expects elected representatives of the people to present their views in the form of intelligent debate especially in the highest court in the land, Parliament ! The reason that the UK government and opposition party's benches are spaced apart as they are, is that was considered to be t...

Added some gear in the last seven months.. - Agilent Modulation Domain Analyzer 53310A with opt. 031 (RF channel C, 2,5Ghz) refitted opt. 001 - "extended memory" myself with NOS RAM power supply completely reworked, all electrolytic caps replaced (measurements less noisy, more to be done ...

It does warn of interaction, though, but this seems to be just between the two controls and not adjacent bands. Less simple in the practical sense because you can't tune it "live" as the adjustments are inaccessible when it's in its screened box and if removed from the box with an extende...

Heroic indeed! That logic implementation is interestingly old-skool! I wonder if they really did it to keep the noise down? Conceivable, but a bit perverse. It's the only reason that seems realistic, according to a few replies I got on Mastodon or Bluesky this was built for EMC performance above ev...

Again, on behalf of all sane Americans... I'm sorry. :oops: We in the UK are prone to similar problems. Currently the name of the desperation fantasy is "Farage". They are neither the cause nor the cure but they are the manifestation of the desperation, cf Hitler in the 30s. To try and un...

Interestingly, one of my favourite authors, J. Michael Straczynski who created Babylon 5, has spent most of his savings over the past 8 months trying to escape the US. That's unsurprising considering the history lessons he wove into B5. He's just managed to get UK residency, and is just setting up w...
