Humans didn’t come with wings from the factory, and most efforts to fit them after the fact have been at least as far as flight is concerned, largely fruitless. That doesn’t mean you can’t cut a devastatingly sharp aesthetic though, and [Natalina’s] fiber optic wings are a great way to do just that. The wings […]
Over the years we’ve seen several attempts at adding Internet connectivity to the lowly wired doorbell. Generally, these projects aim to piggyback on the existing wiring, bells, and buttons rather than replace them entirely. Which invariably means at some point the AC wiring is going to need to interface with a DC microcontroller. This is […]
Can you generate VGA and handle a PS/2 keyboard with a Cortex-M4 in Rust? That’s precisely what [theJPster] wanted to find out with Monotron, a 1980s style home computer programmed in pure Rust. In order to run embedded Rust without a working operating system, some tools are necessary: an LLVM back-end for generating machine code, […]
Sometimes, mechanical parts can be supremely expensive, or totally unavailable. In those cases, there’s just one option — make it yourself. It was this very situation in which I found myself. My electric scooter had been ever so slightly bested by a faster competitor, and I needed redemption. A gearing change would do the trick, […]
Join us on Wednesday, October 23 at noon Pacific for the Open Hardware Month Hack Chat with Michael Weinberg! It seems like everything and everyone has a special day set aside on the calendar. You know the drill – a headline declaring it National Grilled Cheese Day (sorry, you missed it – April 12) or […]
While there are some fixed-wing drones in the hobby world, most of us around here think of the quadcopter when this word is mentioned. There have been some fixed-wings around, and lots of multi-rotors, but not much of a mix of the two. [Paweł] wanted to see what would happen if he mixed these two […]
Openness has been one of the defining characteristics of the Internet for as long as it has existed, with much of the traffic today still passed without any form of encryption. Most requests for HTML pages and associated content are in plain text, and the responses are returned in the same way, even though HTTPS […]
While the Arduino has a very vocal fan club, there are always a few people less than thrilled with the ubiquitous ecosystem. While fans may just dismiss it as sour grapes, there are a few legitimate complaints you can fairly level at the stock setup. To address at least some of those concerns, Arduino is […]
During the late 1980s, a gaming scene emerged in East Germany just before the fall of communism. Teenagers gathered in buildings like the “House of Young Talents” (HdjT), originally Palais Podewils, to watch and play Commodore 64 games. There were 20 similar clubs in Berlin alone, sometimes with more than 70 people crowded into a […]
Sometimes debugging just doesn’t go the way you want it to. When USB problems arise, you can usually use a protocol analyzer to find the issue causing trouble. For [Paul Stoffregen], it was only the first step in a long process to find the culprit. Procotol Analyzer The complaint that came up was from a […]
