[Garage 54] is no stranger to vehicle-related projects of the “because why not?” variety, and their latest is using 50 cordless drills combined into a monstrous mega-motor to turn a gutted (and extended) Lada into an electric vehicle (EV). Doing this leans on some of [Garage 54]’s earlier projects, such as replacing the aforementioned Lada’s […]
When [Tahmid Mahbub] recently reached for his ‘Lavolta’ BPS-305 bench supply, he was dismayed to find that despite it being a 30V, 5A-rated unit, the supply refused to output more than 15V. To be fair, he wasn’t sure that he had ever tried to push it beyond 15V in the years that he had owned […]
Within our comfortable world of causality we expect that reactions always follow an action and not vice versa. This why the recent chatter in the media about researchers having discovered ‘negative time’ with photons being emitted before the sample being hit by source photons created such a stir. Did these researchers truly just crack our […]
The world of audio has produced a variety of different loudspeaker designs over the last century, though it’s fair to say that the trusty moving coil reigns supreme. That hasn’t stopped plenty of engineers from trying new ways to make sound though, and [R.U.H] is here with a home-made version of one of them. It’s […]
Around here, we love it when someone identifies a need and creates their own solution. In this case, [Engineer Bo] was tired of endless and imprecise scrolling with a mouse wheel. No off-the-shelf solutions were found, and other DIY projects either just used hacked mice scroll wheels, customer electronics with low-res hardware encoders, or featured […]
A bit ago, I’ve told you about how the Sony Vaio motherboard replacement started, and all the tricks I used to make it succeed on the first try. How do you plan out the board, what are good things to keep in mind while you’re sourcing parts, and how do you ensure you finish the […]
One of the longest running jokes in our sphere is that the coming year will finally be the year of “Linux on the Desktop.” Never mind that the erosion of the traditional Windows-style desktop form of computing is a thing, or that Linux-derived operating systems such as Android or Chrome OS are running on literally […]
The Proxmark3 PCB 125kHz antenna., GNU GPL version 2, GitHub link. Picture this: It’s the end of the year, and a few hardy souls gather in a hackerspace to enjoy a bit of seasonal food and hang out. Conversation turns to the Flipper Zero, and aspects of its design, and one of the parts we […]
It’s not something we always think about, but the reality is that many of the affordable electronic components we enjoy today are only available to us because they’re surplus parts intended for commercial applications. The only reason you can pick up something like a temperature sensor for literal pennies is because somebody decided to produce […]
