Coin Cell Eliminator Does More Than Save Batteries

Posted by in categories: electronics, energy

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.

DIY Hydrophone Listens In On The Deep For Cheap

Posted by in categories: electronics, military

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.

Joby under NTSB scanner after air taxi prototype crashes in California

Posted by in categories: electronics, transportation

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.

VR’s Biggest Ad Yet Pushed ‘Meta Quest’ to a National Audience During the Super Bowl

Posted by in categories: electronics, virtual reality

It’s hard to find a single event with a bigger audience than the Super Bowl, which has made it one of the hottest pieces of advertising real estate anywhere. Meta went big this year with a 60 second ad spot that served to both promote VR to a national audience and solidify its rebranding from Oculus Quest 2 to Meta Quest 2.

If you were watching the Rams and Bengals duke it out during Super Bowl 56 on Sunday, you will also have been introduced to ‘Questy’s’ in an ad during the first quarter. The 60 second spot, which centered around a personified animatronic band that once played at a restaurant called Questy’s, was likely the single most expensive VR-related ad ever shown on TV to date.
