Looks like [Sam Zeloof] got bored on his Thanksgiving break, and things got a little weird in his garage. Of course when your garage contains a scanning electron microscope, the definition of weird can include experimenting with electron-beam lithography, resulting in tiny images etched into silicon. You’ll probably remember [Sam] from his 2018 Hackaday Superconference […]
The greatest hardware hacks of all time were simply the result of finding software keys in memory. The AACS encryption debacle — the 09 F9 key that allowed us to decrypt HD DVDs — was the result of encryption keys just sitting in main memory, where it could be read by any other program. DeCSS, the […]
When we think of physics experiments, we tend to envision cavernous rooms filled with things like optical benches, huge coils in vacuum chambers, and rack after rack of amplifiers and data acquisition hardware. But it doesn’t have to be that way – you can actually perform laser interferometry with a single component and measure sub-micron […]
The Hackaday Superconference is over, which is a shame, but one of the great things about our conference is the people who manage to trek out to Pasadena every year to show us all the cool stuff they’re working on. One of those people was [Piotr Esden-Tempski], founder of 1 Bit Squared, and he brought […]
The Moka pot is an industrial design classic, hailing from Italy in the early part of the 20th century. To this day, it remains an excellent way to brew top quality coffee at home with affordable equipment. However, if your tastes for coffee lie more towards lattes than espresso, you’re out of luck – unless […]
Some plants react quickly enough for our senses to notice, such as a Venus flytrap or mimosa pudica. Most of the time, we need time-lapse photography at a minimum to notice while more exotic sensors can measure things like microscopic pores opening and closing. As with any sensor reading, those measurements can be turned into […]
Intel just announced their new Sunny Cove Architecture that comes with a lot of new bells and whistles. The Intel processor line-up has been based off the Skylake architecture since 2015, so the new architecture is a fresh breath for the world’s largest chip maker. They’ve been in the limelight this year with hardware vulnerabilities exposed, known […]
Electric vehicles of all types are quickly hitting the market as people realize how inexpensive they can be to operate compared to traditional modes of transportation. From cars and trucks, to smaller vehicles such as bicycles and even electric boats, there’s a lot to be said for simplicity, ease of use, and efficiency. But sometimes […]
When we think of pneumatic actuators, we typically consider the standard varieties of pneumatic cylinder, capable of linear motion. These can be referred to as “hard” actuators, made of rigid components and capable of great accuracy and force delivery. However, “soft” actuators have their own complementary abilities – such as being able to handle more […]
Ground is an interesting topic when it comes to engineering. Either it’s the reference level for a digital circuit (not necessarily at zero volts, either), or it’s the return path for current, or it’s the metal chassis, which shouldn’t be the return path for current or else something’s terribly broken. Erika Earl’s talk at this year’s […]
