As a species, we’ve done a pretty good job at inventing some useful devices. But as clever as we think we are, given sufficient time, natural selection will beat us at our game at almost every turn. So it makes sense that many of our best inventions are inspired by nature and the myriad ways life finds to get DNA from one generation to the next.
Velcro is one such design cribbed from nature, and the story behind this useful mechanism is a perfect example that a prepared mind, good observation skills, and a heck of a lot of perseverance …read more
Unlock & Talk: Open Source Bootloader & Modem
During the early years of cell phones, lifespan was mainly limited by hardware (buttons wearing out, dropping phones, or water damage), software is a primary reason that phones are replaced today.

[Oliver Smith] and the postmarketOS project are working to fix the update problem, and have begun making progress on loading custom software onto cellphone processors and controlling their cellular modems. …read more
Raspberry Pi W Antenna Analysis Reveals Clever Design
The old maxim is that if you pay peanuts, you get a monkey. That’s no longer true, though: devices like the Raspberry Pi W have shown that a $10 device can be remarkably powerful if it is well designed. You might not appreciate how clever this design is sometimes, but this great analysis of the antenna of the Pi W by [Carl Turner, Senior RF Engineer at Laird Technology] might help remind you. …read more
Fix Your Insecure Amazon Fire TV Stick
I recently spent a largely sleepless night at a hotel, and out of equal parts curiosity and boredom, decided to kill some time scanning the guest network to see what my fellow travelers might be up to. As you’d probably expect, I saw a veritable sea of Samsung and Apple devices. But buried among the seemingly endless number of smartphones charging next to their sleeping owners, I found something rather interesting. I was as picking up a number of Amazon-made devices, all of which had port 5555 open.
As a habitual Android tinkerer, this struck me as very odd. Port …read more
