We start off this week with information from Mars, since, let’s facial area it, the information from this planet is not all that a great deal enjoyable recently. But a few of milestones were being achieved on the Crimson Earth, the initial getting the arrival of Perseverance at the ancient river delta it was sent there to check out. The rover definitely took the scenic route to get there, obtaining protected 10.6 km about the past 424 sols to transfer to a position only about 3.5 km straight-line length from wherever it landed. Granted, a good deal of that excess driving was in assist of the unexpectedly prosperous Ingenuity demonstration, in addition using time for a whole lot of pit stops together the way at intriguing features. But the rover is now in location to take a look at sedimentary rocks most very likely to harbor the fossil continues to be of ancient aquatic everyday living — as opposed to the primarily igneous rocks it has researched together the crater flooring so far. We’re seeking ahead to observing what transpires.

Speaking of Ingenuity, the plucky helicopter just keeps on executing. It recently finished its 27th flight — of 5 planned flights, intellect you — and noticed the crashed stays of the aeroshell and parachute from its amazing arrival final February. They seem rather the worse for the use, but which is to be anticipated. The stunningly higher-resolution images Ingenuity despatched back again will no doubt be pored above by engineers for whichever clues it retains about how the framework stood up to descent and landing circumstances. We’re not sure, but this may be the very first time a landing or crash web site has been revisited given that Allan Bean unquestionably nailed the Apollo 12 landing to in walking length of Surveyor 3 in 1969.

“And the Emmy goes to… Comic Sans?” No, not definitely, and apologies to anybody activated by the point out of The Font That Shall Not Be Utilized. But this 7 days the 2021 Technological know-how & Engineering Emmy award went to the Planet Broad Internet Consortium (W3C) Net fonts Functioning Group and MPEG together for “standardizing font technological know-how for customized downloadable fonts and typography for world-wide-web and Television set devices.” To be apparent, the award is not for any unique font, but instead the technological achievement of downloadable fonts. Nevertheless, it is quick to poke enjoyable at typography, specially when font snobs go on about the deserves of this serif or that descender. But individuals subtle discrepancies that most of us assume are meaningless basically play a substantial job in the “feel” of web sites. World wide web fonts have a ton to do with how polished and professional most web-sites look these times, in comparison to some of the atrocities of the Web 1. times.

A couple of months again, we experienced a PCB Thermal Structure Hack Chat above on Hackaday.io with Mike Jouppi. It was a fantastic discussion and spawned an interesting sidebar with attendee Sven about thermal vias. It seems like Sven’s application had a lot for Mike to sink his tooth into, simply because he created an in-depth online video on the thermal layout of this PCB, alongside with a dialogue of what went into creating IPC-2152, the typical for PCB trace current-carrying capacity structure. Thanks to Mark Hughes of State-of-the-art Assembly for the heads up on this, and for suggesting Mike occur on the Hack Chat in the to start with place.


And eventually, it seems like Lichtenberg designs are getting common enough that it’s necessary to alert folks that actively playing with electricity can be unsafe. Lichtenberg styles, which are fractal channels burned into wooden or other elements by the (ideally) judicious software of substantial voltage, are certainly something we’ve found and featured ahead of. On the other hand, the American Association of Woodturners — mainly because of study course there is such a group — now condemns the apply, which evidently has caught on in the woodturning group. The AAW genuinely does not want anyone executing Lichtenbergs — they banned the observe at all their situations and in their publications, enlisted the aid of a medical doctor to convey to anyone that electric power can quit your coronary heart, and urged any person who has fractal woodburning gear to toss it out now right before it assaults. We comprehend and wholeheartedly agree that operating with high voltage can be hazardous, and we’re not declaring that woodturners need to not choose the probably fatal effects of Lichtenbergs critically. But this warning appears to be a little bit abundant coming from an business that encourages its members to stand in front of a equipment that can throw razor-sharp applications at you, fling significant chunks of wooden at your head, or instantaneously alleviate you of your garments — or even worse. Be secure out there, all people.
