Printed circuit boards were once so simple. One or two layers of copper etched on a rectangular fiberglass substrate, with a few holes drilled in key locations so components could be soldered into place. They were functional objects, nothing more—built only for the sake of the circuit itself. Fast forward to today, and so much […]
These days we don’t get too fussed about miniaturized electronics, not when you can put an entire processor and analog circuitry on a chip the size of a grain of sand. Things were quite different back in the 1980s, with the idea of a credit card-sized radio almost preposterous. This didn’t stop the engineers over […]
You might think you don’t need a hearing aid, and you might be right. But in general, hearing loss eventually comes to all of us. In fact, you progressively lose hearing every year, which is why kids can have high-pitched ringtones their parents can’t hear. You’d think hearing aids would be pretty simple, right? After […]
Recently Raspberry Pi publicly announced the release of their new rpi-image-gen tool, which is advertised as making custom Raspberry Pi OS (i.e. Debian for specific Broadcom SoCs) images in a much more streamlined fashion than with the existing rpi-gen tool, or with third-party solutions. The general idea seems to be that the user fetches the […]
Many of us could have been lucky enough to have some form of pedal go-kart in our formative years, and among such lucky children there can have been few who did not wish for their ride to have a little power. Zipping around the neighborhood remained a strenuous affair though, particularly for anyone whose hometown […]
When Apple first launched the Macintosh, it created a new sort of “Lunchbox” form factor that was relatively portable and very, very cool. Reminiscent of that is this neat portable Macintosh Mini, created by [Scott Yu-Jan]. [Scott] has created something along these lines before—putting an iPad dock on top of a Macintosh Studio to create […]
A moment’s inattention is all it takes to gather the information needed to make a physical copy of a key. It’s not necessarily an easy process, though, so if pen testing is your game, something like this Flipper Zero key copying toolchain can make the process quicker and easier when the opportunity presents itself. Of […]
Although NVidia’s current disastrous RTX 50-series is getting all the attention right now, this wasn’t the first misstep by NVidia. Back in 2014 when NVidia released the GTX 970 users were quickly dismayed to find that their ‘4 GB VRAM’ GPU had actually just 3.5 GB, with the remaining 512 MB being used in a […]
There are a million ways to use LEDs to make a clock. [sjm4306] chose to go a relatively conventional route, making something that approximates a traditional analog timepiece. However, he did it using LED filaments to create a striking and unique design. Thus the name—FilamenTIME! LED filaments are still relatively new on the scene. They’re […]
