NASA Found Another Super Earth With Tantalizing Possibilities

Earth is a rather special place, quite unlike the other planets in the solar system. It’s nestled at the perfect distance from the sun to allow our water to remain liquid and for life to flourish in turn. It’s a rare thing; most planets are either too close and scorching hot, or too far and freezing cold.

NASA is always on the hunt for planets like our own, and recently found a new super-Earth by the name of TOI-715b. The planet is larger than our own, but it’s position and makeup mean that it’s a prime candidate for further study. Let’s take a look at how NASA discovered this planet, and why it’s special.

An Automotive Locksmith On The Flipper Zero And Car Theft

Here in the hacker community there’s nothing we love more than a clueless politician making a fool of themselves sounding off about a technology they know nothing about. A few days ago we were rewarded in spades by the Canadian Minister of Innovation, Science and Industry François-Philippe Champagne, who railed against the Flipper Zero, promising to ban it as a tool that could be used to gain keyless entry to a vehicle.

Of course our community has roundly debunked this assertion, as capable though the Flipper is, the car industry’s keyless entry security measures are many steps ahead of it. We’ve covered the story from a different angle before, but it’s worth returning to it for an automotive locksmith’s view on the matter from [Surlydirtbag].

He immediately debunks the idea of the Flipper being used for keyless entry systems, pointing out that thieves have been using RF relay based attacks which access the real key for that task for many years now. He goes on to address another concern, that the Flipper could be used to clone the RFID chip of a car key, and concludes that it can in the case of some very old vehicles whose immobilizers used simple versions of the technology, but not on anything recent enough to interest a car thief.

Of course, to many readers this will not exactly be news. But it’s still important, because perhaps some of us will have had to discuss this story with non-technical people who might be inclined to believe such scare stories. Being able to say “Don’t take it from me, take it from an automotive locksmith” might just help. Meanwhile there is still the concern of CAN bus attacks to contend with, something the manufacturers could have headed off had they only separated their on-board subsystems.

A “Full” Keyboard For $5*

Sure, we’ve all seen PCB business cards at this point, but what about giving away a full-blown keyboard at meetups and such? That’s just how cost-effective the idawgz32 keyboard is. How on Earth can it cost so little? [sporewoh] used the CH552 microcontroller, which comes in around a dollar and only needs a couple of capacitors to get it up and running. The firmware is FAK.

As [sporewoh] writes in this blog post about the keyboard, they did some analysis and realized that most of the cost of their previous tiny board came from the switches. In addition to switching up the switches, [sporewoh] performed a few tricks to get the cost down, like making the key spacing 9 mm x 9 mm so that the overall board is less than 100 mm x 100 mm (which triggers a deal at a certain board house).

Unfortunately, the switches turned out not to be so good. They had greater travel and required more actuation force than the ones [sporewoh] was used to with previous board. The switches were also scratchy, which was solved with a little Krytox. But ultimately, they are pretty unreliable, so the next revision will use Panasonic EVQP0N02Bs.

If this seems familiar, you may be recalling this $3 macro pad which uses the same chip, or maybe the fact that we’ve covered the CH552 in detail.
