A new photo of Magic Leap 2 appears to show the device’s controller equipped with cameras for inside-out tracking which would be the first time we’ve seen the approach employed in a commercial XR headset.

Though we learned plenty of interesting details about the forthcoming Magic Leap 2 AR headset back in January, it looks like there’s still some secrets left to uncover.

A recent photo of Magic Leap 2 posted by Peter H. Diamandis is, as far as we know, the first time we’ve gotten a clear look at the front of the Magic Leap 2 controller. The photo clearly shows what appear to be two camera sensors on the controller, indicating a high likelihood it will have on-board inside-out tracking.

Physics World.

UC Berkeley engineers have come up a new technique for creating wearable sensor prototypes.

The geopolitical tension surrounding.

Cartography could be changing forever as an advanced tool moves from the lab to the real world. A new quantum gravity sensor helps overcome an issue raised by Einstein.

Coin cells are useful things that allow us to run small electronic devices off a tiny power source. However, they don’t have a lot of capacity, and they can run out pretty quickly if you’re hitting them hard when developing a project. Thankfully, [bobricius] has just the tool to help.

The device is simple – it’s a PCB sized just so to fit into a slot for a CR2016 or CR2032 coin cell. The standard board fits a CR2016 slot thanks to the thickness of the PCB, and a shim PCB can be used to allow the device to be used in a CR2032-sized slot instead.

It’s powered via a Micro USB connector, and has a small regulator on board to step down the 5 V supply to the requisite 3 V expected from a typical coin cell. [bobricius] also gave the device a neat additional feature – a pair of pads for easy attachment of multimeter current probes. Simply open the jumper on the board, hook up a pair of leads, and it’s easy to measure the current being drawn from the ersatz coin cell.

The microphone is a pretty ubiquitous piece of technology that we’re all familiar with, but what if you’re not looking to record audio in the air, and instead want to listen in on what’s happening underwater? That’s a job for a hydrophone! Unfortunately, hydrophones aren’t exactly the kind of thing you’re likely to find at the big-box electronics store. Luckily for us, [Jules Ryckebusch] picked up a few tricks in his 20-year career as a Navy submariner, and has documented his process for building a sensitive hydrophone without needing a military budget.

The US National Transportation Safety Board (NTSB) says it is investigating the February 16 crash of a Joby Aviation air taxi prototype in Jolon, California.

The experimental air taxi was being piloted remotely when it went down during a flight at the company’s test base on Wednesday. According to a preliminary report by the FAA, no injuries have been reported.

Equipping ROSALIND, a cell-free biosensing platform, with information processing circuits based on toehold-mediated DNA strand displacement enhances sensor performance and enables logic gate computation.

Glacier Peak in Snohomish County is currently at a “very high” threat for eruption — the top classification of threat levels, according to federal scientists.
