With the powerful off-the-shelf hardware available to us common hardware hobbyist folk, how hard can it be to make a smartphone from scratch? Hence [V Electronics]’s Spirit smartphone project, with the video from a few months ago introducing the project. As noted on the hardware overview page, everything about the project uses off the shelf […]
Modern cellular networks are built to serve millions upon millions of users, all while maintaining strict encryption across all communications. But earlier cellular networks were by no means so secure, as [Nostalgia for Simplicity] demonstrates in a recent video. The video begins with an anecdote — our narrator remembers a family member who could listen […]
Calendar aging of NMC Li-ion cells at 50 ℃ at various SoCs. (Credit: Wiljan Vermeer, IEEE, 2021) With batteries being such an integral part of smartphones, it’s little wonder that extending the period between charging and battery replacement has led to many theories and outright myths about what may affect the lifespan of these lithium-ion […]
To update an old saying for the modern day, one man’s e-waste is another man’s bill of materials. Upcycling has always been in the hacker’s toolkit, and cellphones provide a wealth of resources for those bold enough to seize them. [Huy Vector] was bold enough, and transformed an old smartphone into a portable pico projector […]
These days, most of us have a smartphone. They are so commonplace that we rarely stop to consider how amazing they truly are. The open-source project Phyphox has provided easy access to your phone’s sensors for over a decade. We featured it years ago, and the Phyphox team continues to update this versatile application. Phyphox […]
The phone ecosystem these days is horribly boring compared to the innovation of a couple decades back. Your options include flat rectangles, and flat rectangles that fold in half and then break. [Marcin Plaza] wanted to think outside the slab, without reinventing the wheel. In an inspired bout of hacking, he flipped a broken Samsung […]
Smartphones boggle my mind a whole lot – they’re pocket computers, with heaps of power to spare, and yet they feel like the furthest from it. As far as personal computers go, smartphones are surprisingly user-hostile. In the last year’s time, even my YouTube recommendations are full of people, mostly millennials, talking about technology these […]
It’s often said that what’s inside matters more than one’s looks, but it’s hard to argue that a product’s looks and its physical user experience are what makes it instantly recognizable. When you think of something like a Walkman, an iPod music player, a desktop computer, a car or a TV, the first thing that […]
Normal people binge-scroll social media. Hackaday writers tend to pore through online tech news and shopping sites incessantly. The problem with the shopping sites is that you wind up buying things, and then you have even more projects you don’t have time to do. That’s how I found the MAKE-roscope, an accessory aimed at kids […]
