Hackaday Links: February 15, 2026

It probably won’t come as much of a surprise to find that most of the Hackaday staff aren’t exactly what you’d call sports fanatics, so we won’t judge if you didn’t tune in for the Super Bowl last week. But if you did, perhaps you noticed Ring’s Orwellian “Search Party” spot — the company was hoping to get customers excited about a new feature that allows them to upload a picture of their missing pet and have Ring cameras all over the neighborhood search for a visual match. Unfortunately for Ring, the response on social media wasn’t quite what they expected.

One commenter on YouTube summed it up nicely: “This is like the commercial they show at the beginning of a dystopian sci-fi film to quickly show people how bad things have gotten.” You don’t have to be some privacy expert to see how this sort of mass surveillance is a slippery slope. Many were left wondering just who or what the new system would be searching for when it wasn’t busy sniffing out lost pups.

The folks at Wyze were quick to capitalize on the misstep, releasing their own parody ad a few days later that showed various three-letter agencies leaving rave reviews for the new feature. By Thursday, Ring announced they would be canceling a planned expansion that would have given the divisive Flock Safety access to their network of cameras. We’re sure it was just a coincidence.

Speaking of three-letter agencies, the Environmental Protection Agency has announced this week that they will no longer incentivize the inclusion of stop-start systems on new automobiles. The feature, which shuts off the engine when the vehicle comes to a stop, was never actually required by federal law; rather, the EPA previously awarded credits to automakers that added the feature, which would help them meet overall emission standards. Manufacturers are free to continue offering stop-start systems on their cars if they wish, but without the EPA credits, there’s little benefit in doing so. Especially since, as Car and Driver notes, it seems like most manufacturers are happy to be rid of it. The feature has long been controversial with drivers as well, to the point that we’ve seen DIY methods to shut it off.

Stunning Footage Of Perseverance Landing On Mars

February 22, 2021 by Dan Maloney 70 Comments

The much-anticipated video from the entry descent and landing (EDL) camera suite on the Perseverance rover has been downlinked to Earth, and it does not disappoint. Watch the video below and be amazed.

The video was played at the NASA press conference today, which is still ongoing as we write this. The brief video below has all the highlights, but the good stuff from an engineering perspective is in the full press conference. The level of detail captured by these cameras, and the bounty of engineering information revealed by these spectacular images, stands in somewhat stark contrast to the fact that they were included on the mission mainly as an afterthought. NASA isn’t often in the habit of adding “nice to have” features to a mission, what with the incredible cost-per-kilogram of delivering a package to Mars. But thankfully they did, using mainly off-the-shelf cameras.

The camera suite covered nearly everything that happened during the “Seven Minutes of Terror” EDL phase of the mission. An up-looking camera saw the sudden and violent deployment of the supersonic parachute — we’re told there’s an Easter egg encoded into the red-and-white gores of the parachute — while a down-looking camera on the rover watched the heat shield separate and fall away. Other cameras on the rover and the descent stage captured the skycrane maneuver in stunning detail, both looking up from the rover and down from the descent stage. We were surprised by the amount of dust kicked up by the descent engines, which fully obscured the images just at the moment of “tango delta” — touchdown of the rover on the surface. Our only complaint is not seeing the descent stage’s “controlled disassembly” 700 meters away from the landing, but one can’t have everything.

Honestly, these are images we could pore over for days. The level of detail is breathtaking, and the degree to which they make Mars a real place instead of an abstract concept can’t be overstated. Hats off to the EDL Imaging team for making all this possible.
