[ad_1] A DIY weather display with dedicated outdoor sensor station Arduino Team — June 10th, 2024 Weather stations are popular projects in the maker community because they’re useful and usually quite affordable to construct. But most that we see are really weather information displays that gather data through the internet from stations in the region. That data […]

[ad_1] When you hand your new acquaintance one of your cards, there’s a chance you might feel an instant connection. But what if you could know almost instantly whether they felt the same way? With the Dr. Love card, you can erase all doubt. As you may have guessed, the card uses Galvanic Skin Response. […]

[ad_1] Apple is well-known for its secrecy, which is understandable given the high stakes in the high-end mobile phone industry. It’s interesting to get a glimpse inside its durability labs and see the equipment and processes it uses to support its IP68 ingress claims, determine drop ability, and perform accelerated wear and tear testing. Check […]

[ad_1] What was the worst thing about the 70s? Some might say the oil crisis, inflation, or even disco. Others might tell you it was 8-track tapes, no matter what was on them. I’ve heard that the side of the road was littered with dead 8-tracks. But for a while, they were the only practical […]

[ad_1] If you follow the world of microcontrollers, then you’ll probably be familiar with the most recent crop of ten cent parts. They bring power and features previously the preserve of much more expensive chips into the super-budget arena, and they’re appearing in plenty of projects on these pages. If you’re not familiar with them […]

[ad_1] While most of us have likely spun up a virtual machine (VM) for one reason or another, venturing into the world of containerization with software like Docker is a little trickier. While the tools Docker provides are powerful, maintain many of the benefits of virtualization, and don’t use as many system resources as a […]

[ad_1] Using an external MCU as a crude clock source for the Altera CPLD. (Credit: [Doug Brown]) One exciting feature of hardware development involving MCUs and FPGAs is that you all too often need specific tools to program them, with [Doug Brown] suffering a price tag aneurysm after checking the cost of an official Altera/Intel […]

[ad_1] We aren’t sure how accurate you can get with LEGO, but a building block orrery looks cool, if nothing else. [Marian42] saw one done a few years ago and decided to build a version with a different mechanism. At first, the plan was to use some 3D printed fixtures, but the final product is […]

[ad_1] We’ve been harping a lot lately about the effort by carmakers to kill off AM radio, ostensibly because making EVs that don’t emit enough electromagnetic interference to swamp broadcast signals is a practical impossibility. In the US, push-back from lawmakers — no doubt spurred by radio industry lobbyists — has put the brakes on […]

[ad_1] Intel has had a deathgrip on the PC world since the standardization around the software and hardware available on IBM boxes in the 90s. And if you think you’re free of them because you have an AMD chip, that’s just Intel’s instruction set with a different badge on the silicon. At least AMD licenses […]
