This week, Jonathan Bennett and Rob Campbell talk with Alistair Woodman about FRRouting, the Internet routing suite that helps make all this possible. But also business, and how an open source project turns the corner into a successful way to support programmers. FRR https://github.com/FRRouting/frr https://frrouting.org/ Erlang Ecosystem Foundation https://erlef.org/ Did you know you can watch […]
If you have access to a laser cutter, we sincerely hope you’re aware of boxes.py. As the name implies, it started life as a Python tool for generating parametric boxes that could be assembled from laser-cut material, but has since become an invaluable online resource for all sorts of laser projects. Plus, you can still […]
When [Rodrigo Feliciano] realized that the reason his seven-segment LED wall clock wasn’t working was because the original TG1508D5V5 controller was fried, he had a decision to make. He could either chuck the whole thing, or put in the effort to reverse engineer how the displays were driven and replace the dead controller with something […]
[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 […]
