Conway’s Game of Life excels in its simplicity, creating a cellular automaton on a 2D grid where each cell obeys a set of very simple rules that determine whether a cell is ‘alive’ or ‘dead’. After setting an initial condition the ‘game’ then evolves naturally from there, creating an endless series of patterns as a […]
The final second prototype flying. (Credit: Luke Maximo Bell, YouTube) The dream of fully powering everything from aircraft to cars on just the power generated from solar panels attached to the machine remains a tempting one, but always seems to require some serious engineering including putting the machine on a crash diet. The quadcopter that […]
Power banks come in many sizes, and those that target construction sites are probably among the largest. The massive four ton unit based around lead-acid batteries which the [Buy it Fix it] YouTube channel got handed is a good example. Inside it are Victron CCGX inverters among a lot of other Victron electronics, with the […]
As the sun goes down on a glorious spring evening on the western edge of Europe, Elliot Williams is joined by Jenny List for a look at the week in all things Hackaday. First up: Hackaday Europe tickets are on sale! Bad luck folks, the early bird tickets disappeared in an instant, but regular ones […]
Sometimes you wanna test a piece of USB hardware, but you don’t just want to plug it into a random old phone charger. [KS-Elektronikdesign] has whipped up a useful tool for just that case, allowing one to easily power USB hardware from a common bench supply. It would have been simple enough to whip up […]
The ides of security March are upon us — Qualys reports the discovery by their threat research unit of vulnerabilities in the Linux AppArmor system used by SUSE, Debian, Ubuntu, and Kubernetes as an additional security mechanism and application firewall. AppArmor was added to Linux in 2010, and the vulnerabilities Qualys discovered have been present since […]
It’s no secret that Google really doesn’t like it that people are installing Android applications from any other source than the Play Store. Last year they proposed locking everyone into their official software repository by requiring all apps to be signed by verified developers, an identity which would be checked against a Google-maintained list. After […]
We’re not exactly worried about Armageddon here at Hackaday, but should we end up facing the end of the world as we know it, having something to pass the time would be nice. That’s why we were intrigued by [Janus Cycle]’s latest video where he both plays and powers a Game Boy by candlelight. You’ve […]
The Raspberry Pi line of single-board computers can be hooked up with a wide range of compatible cameras. There are a number of first party options, but you don’t have to stick with those—there are other sensors out there with interesting capabilities, too. [Collimated Beard] has been exploring the use of the IMX585 camera sensor, […]
The test setup for the Battle Born LFP cycling. (Credit: Will Prowse, YouTube) There has been quite a bit of news recently about the Battle Born LiFePO4 (LFP) batteries and how they are dying in droves if not outright melting their plastic enclosures. Although the subsequent autopsies show molten plastic spacers on the bus bars […]
