Chances are pretty good that at some time in your life, you’ve crossed paths with a norovirus. And chances are that you remember the encounter vividly, or at least its aftermath. I recall a run-in with the bug one Christmas, when my parents brought over more than just toys for the kids when they visited. […]
Having a motorized gate on your driveway is great, but only if there’s an easy way to trigger it. [Andrew] says the gate at his parent’s place could only be controlled by manually pushing a button on the panel or with a dinky remote that didn’t have nearly the range they wanted. So he decided […]
If you’ve heard of core rope memory, it will probably be in the context of vintage computing equipment such as Apollo-era NASA hardware. A string of magnetic cores and sense wires form a simple ROM arrangement, which though long-ago-superceded by semiconductor memory remains possible to recreate by the experimenter. It’s a path [Nicola Cimmino] has […]
At risk of getting any ASMR buffs who might be reading cranky because there’s no audio, [Chris], or [@no1089] on Twitter, has gifted us with this visually stunning scan of his Maxim MAX86160 in-ear heart monitor mounted on a rigidflex PCB. You can take a look, in the video below the break. If you’re wondering […]
[Voltlog] has had a 952 hot air rework station for a long time. You’ll recognize it when you see it — they are the ubiquitous soldering iron and hot air gun combination from China sold under numerous brand names. He didn’t think the old station was as good as some of the newer devices available, […]
At this point you’d need to have lived underneath a rock somewhere on the dark side of the Moon to not have heard about these amazing, 3-cent microcontrollers. A number of places have pitched in on them, but comprehensive reviews, let alone a full-blown review of the entire ecosystem surrounding these Padauk MCUs have been […]
USB first hit the scene in the 1990s, and was intended to simplify connecting peripherals to PCs and eliminate the proliferation of various legacy interfaces. Over 20 years later, it’s not only achieved its initial goals, but become a de facto standard for charging and power supply for all manner of personal electronic gadgets. If […]
If there is one thing that most Hackaday readers will know about Denmark, it is that it’s the home of the Lego brick. The toy first appeared at the end of the 1940s from the factory of Ole Kirk Christiansen‘s Lego company in Billund, central Denmark, and has remained inseparable from both the town and […]
We’ve noticed a trend lately that advanced 3D printing people are calling their normal print setup as 2.5D, not 3D. The idea is that while the machine has 3 axes, the actual geometry generation is typically only in the X and Y axis. The Z axis simply lifts up to the next layer unless you […]
Join us on Wednesday, September 11 at noon Pacific for the Machine Learning with Microcontrollers Hack Chat with Limor “Ladyada” Fried and Phillip Torrone from Adafruit! We’ve gotten to the point where a $35 Raspberry Pi can be a reasonable alternative to a traditional desktop or laptop, and microcontrollers in the Arduino ecosystem are getting powerful enough […]
