We begin this 7 days with information from Mars, because, let’s experience it, the information from this earth is not all that a lot exciting recently. But a couple of milestones have been arrived at on the Pink Earth, the very first getting the arrival of Perseverance at the historical river delta it was despatched there to take a look at. The rover unquestionably took the scenic route to get there, getting protected 10.6 km more than the previous 424 sols to shift to a placement only about 3.5 km straight-line length from where it landed. Granted, a good deal of that more driving was in assistance of the unexpectedly successful Ingenuity demonstration, as well as taking time for a lot of pit stops along the way at appealing capabilities. But the rover is now in place to analyze sedimentary rocks most probably to harbor the fossil stays of historical aquatic lifestyle — as opposed to the predominantly igneous rocks it has studied alongside the crater ground so considerably. We’re searching ahead to viewing what comes about.
Speaking of Ingenuity, the plucky helicopter just keeps on executing. It a short while ago concluded its 27th flight — of five planned flights, thoughts you — and noticed the crashed stays of the aeroshell and parachute from its amazing arrival previous February. They seem really the even worse for the dress in, but that’s to be predicted. The stunningly superior-resolution shots Ingenuity sent again will no question be pored over by engineers for no matter what clues it holds about how the structure stood up to descent and landing circumstances. We’re not positive, but this may possibly be the initial time a landing or crash web-site has been revisited considering the fact that Allan Bean unquestionably nailed the Apollo 12 landing to inside walking distance of Surveyor 3 in 1969.
“And the Emmy goes to… Comedian Sans?” No, not truly, and apologies to any individual brought on by the mention of The Font That Shall Not Be Used. But this 7 days the 2021 Technological know-how & Engineering Emmy award went to the Entire world Extensive Internet Consortium (W3C) Internet fonts Operating Team and MPEG collectively for “standardizing font technology for customized downloadable fonts and typography for world-wide-web and Television set gadgets.” To be crystal clear, the award is not for any distinct font, but instead the specialized accomplishment of downloadable fonts. Even now, it is straightforward to poke pleasurable at typography, specifically when font snobs go on about the deserves of this serif or that descender. But those delicate variances that most of us believe are meaningless basically perform a enormous part in the “feel” of web sites. World-wide-web fonts have a large amount to do with how polished and professional most web sites glimpse these times, when compared to some of the atrocities of the World-wide-web 1. days.
A pair of weeks again, we experienced a PCB Thermal Structure Hack Chat above on Hackaday.io with Mike Jouppi. It was a excellent discussion and spawned an exciting sidebar with attendee Sven about thermal vias. It looks like Sven’s software experienced a great deal for Mike to sink his tooth into, simply because he made an in-depth video on the thermal structure of this PCB, together with a discussion of what went into creating IPC-2152, the regular for PCB trace current-carrying capacity style. Many thanks to Mark Hughes of Sophisticated Assembly for the heads up on this, and for suggesting Mike come on the Hack Chat in the very first position.
And lastly, it appears like Lichtenberg styles are acquiring well known more than enough that it is necessary to alert folks that enjoying with electric power can be risky. Lichtenberg designs, which are fractal channels burned into wooden or other components by the (hopefully) judicious software of large voltage, are undoubtedly a little something we have found and showcased in advance of. Even so, the American Affiliation of Woodturners — simply because of system there’s these types of a group — now condemns the exercise, which apparently has caught on in the woodturning community. The AAW actually doesn’t want any one executing Lichtenbergs — they banned the practice at all their occasions and in their publications, enlisted the assist of a physician to explain to every person that energy can quit your heart, and urged anybody who has fractal woodburning gear to throw it out now right before it assaults. We comprehend and wholeheartedly concur that performing with superior voltage can be dangerous, and we’re not indicating that woodturners really should not consider the potentially lethal outcomes of Lichtenbergs critically. But this warning would seem a little bit abundant coming from an firm that encourages its members to stand in entrance of a device that can throw razor-sharp equipment at you, fling hefty chunks of wooden at your head, or immediately alleviate you of your outfits — or worse. Be risk-free out there, everyone.
