We begin this week with news from Mars, because, let us experience it, the news from this earth is not all that much exciting currently. But a few of milestones were being achieved on the Crimson Earth, the first being the arrival of Perseverance at the historical river delta it was despatched there to take a look at. The rover definitely took the scenic route to get there, possessing covered 10.6 km in excess of the last 424 sols to move to a situation only about 3.5 km straight-line distance from in which it landed. Granted, a ton of that further driving was in assist of the unexpectedly effective Ingenuity demonstration, furthermore having time for a great deal of pit stops along the way at interesting options. But the rover is now in position to take a look at sedimentary rocks most probably to harbor the fossil stays of historic aquatic life — as opposed to the largely igneous rocks it has examined along the crater ground so significantly. We’re looking forward to viewing what comes about.

Talking of Ingenuity, the plucky helicopter just keeps on carrying out. It just lately accomplished its 27th flight — of five prepared flights, head you — and spotted the crashed stays of the aeroshell and parachute from its spectacular arrival past February. They glimpse really the worse for the put on, but that is to be envisioned. The stunningly superior-resolution shots Ingenuity sent back again will no doubt be pored around by engineers for whatever clues it retains about how the composition stood up to descent and landing ailments. We’re not certain, but this could be the first time a landing or crash site has been revisited because Allan Bean certainly nailed the Apollo 12 landing to within just strolling length of Surveyor 3 in 1969.

“And the Emmy goes to… Comic Sans?” No, not definitely, and apologies to anybody brought on by the point out of The Font That Shall Not Be Utilised. But this week the 2021 Technology & Engineering Emmy award went to the Entire world Vast Website Consortium (W3C) Web fonts Working Team and MPEG together for “standardizing font technology for custom made downloadable fonts and typography for internet and Tv equipment.” To be crystal clear, the award is not for any distinct font, but relatively the specialized achievement of downloadable fonts. Nonetheless, it is quick to poke enjoyment at typography, primarily when font snobs go on about the deserves of this serif or that descender. But those subtle distinctions that most of us assume are meaningless actually enjoy a enormous purpose in the “feel” of internet sites. Internet fonts have a large amount to do with how polished and qualified most internet sites appear these days, as opposed to some of the atrocities of the World-wide-web 1. times.

A few of weeks back again, we experienced a PCB Thermal Structure Hack Chat about on Hackaday.io with Mike Jouppi. It was a wonderful dialogue and spawned an intriguing sidebar with attendee Sven about thermal vias. It appears like Sven’s application experienced lots for Mike to sink his tooth into, for the reason that he built an in-depth video on the thermal style and design of this PCB, together with a dialogue of what went into creating IPC-2152, the common for PCB trace current-carrying potential style. Many thanks to Mark Hughes of Innovative Assembly for the heads up on this, and for suggesting Mike come on the Hack Chat in the initially location.

And lastly, it appears to be like like Lichtenberg styles are acquiring well-known sufficient that it’s vital to alert people that enjoying with electrical power can be hazardous. Lichtenberg designs, which are fractal channels burned into wooden or other resources by the (with any luck ,) considered application of significant voltage, are unquestionably something we’ve witnessed and highlighted before. On the other hand, the American Affiliation of Woodturners — for the reason that of system there’s such a team — now condemns the apply, which evidently has caught on in the woodturning local community. The AAW truly doesn’t want any one accomplishing Lichtenbergs — they banned the apply at all their situations and in their publications, enlisted the support of a health practitioner to notify anyone that electrical power can stop your coronary heart, and urged anyone who has fractal woodburning gear to toss it out now ahead of it assaults. We fully grasp and wholeheartedly concur that doing work with large voltage can be dangerous, and we’re not stating that woodturners should really not choose the likely deadly effects of Lichtenbergs very seriously. But this warning looks a bit abundant coming from an group that encourages its associates to stand in entrance of a machine that can throw razor-sharp instruments at you, fling major chunks of wood at your head, or promptly relieve you of your clothes — or worse. Be harmless out there, all people.
