Rollercoasters Are Triggering The IPhone’s Crash Detection System

October 12, 2022 by 68 Comments

Apple has been busy adding new features to its smartphone and smartwatch offerings. Its new iPhone 14 and Apple Watch 8 now feature a safety system that contacts emergency services in the event the user is in a automobile accident.

As with so many new technologies though, the feature has fallen afoul of the law of unintended consequences. Reports are that the “crash detection system” is falsely triggering on rollercoasters and in other strange circumstances. Let’s take a look at how these systems work, and why this might be happening.

A futuristic bed headboard has a continuous light with a hexagonal grid overlaid on top of it that wraps around the bed, much like an ovoid MRI machine.

This Headboard Contains An Artificial Sun

Despite the proliferation of artificial lighting, humans are still highly dependent on sunlight for regulation of our circadian rhythms. Accordingly, [Sector 07] has built a futuristic headboard that can help with the waking up side of things whether you’re headed to space or just in the dead of winter.

The interior of the headboard includes custom 3D printed panels to mount the electronics and a light diffusion screen made of nylon fabric. The printed parts were all joined by “welding” the pieces with a soldering iron and extra filament. Besides the futuristic hexagon motif in the diffusion screen, the most eye-catching part of this build is the curved ends making it look like a set piece from Star Trek: TNG. [Sector 07] was able to get the unique shape by kerf bending the plywood ends before joining them to the flat sections with dowels and wood glue.

Since this build also includes an integrated coffee maker and voice assistant, there’s a bit more going on with the electronics than you might have in a normal circadian lamp. Powering the project are two Arduino Mega boards and a SpeakUp Click that handles the voice commands. Wake-up times are controlled via a keypad, and the voice assistant, Prisma, will ask if you are awake once the 30 minute sun simulation has completed before your alarm goes off. If you don’t confirm wakefulness, Prisma will escalate alarms until the system is sure you’re awake and then will ask if you want coffee. If you want a deep dive into the system’s functionality, be sure to checkout the video after the break.

We’ve covered artificial suns before, so if you’re interested in trying to build you’re own you should check out this Hugely Bright Artificial Sun, a Sunrise Alarm Clock Mounted Above the Bed, and this Artificial Sun Via Old Satellite Dishes.

Hacking Developers With A Cat Feeder: Who’s A Good Kitty?

October 12, 2022 by 4 Comments

Most of us probably know the drudgery of getting through some coding work, with just tedious hours of monkeying around stretching ahead of us. What if this tedium were to be interrupted by an occasional reward when we did something productive, like pushing a commit or other measure of progress? That’s roughly the concept that [John Partee] started off with when his gaze fell upon one of those automated cat feeders. Cat or developer, who doesn’t like to hear the tinkle of a tasty treat falling into their bowl?

The target pet feeder is a PetKit Fresh Element Solo, which allows for objects with a size of 12×12 mm (any orientation) to be fed through the feeding mechanism. Fortunately [John]’s favorite dark chocolate-covered almonds treat fit these requirements, and he set to work to figure out the REST API call needed to trigger a manual feeding event on the cat feeder device, employing the existing PyPetKit Python library that does the heavy lifting of connecting to and communicating with PetKit’s servers, as the feeder is of course an IoT device.

This means that the event flow still depends on PetKit’s “cloud”, which may inspire some enterprising hackers to make a stand-alone version, the development of which may be assisted by [John]’s solution through a regular treat. Before taking such a solution into use, be sure to discuss it with any pets you have, as they may not quite comprehend why there’s no reward for them whenever the *tinkle* sound occurs.
