As far as timekeeping goes, there’s nothing more accurate and precise than an atomic clock. Unfortunately, we can’t all have blocks of cesium in our basements, so various agencies around …read more Continue reading Simulating a Time-Keeping Radio Signal
Analog acquisition tools are super helpful whenever you want to run an experiment, test out a theory, or improve upon your code, and you won’t realize how much you always …read more Continue reading Add the Analog Toolkit to Your…Toolkit
We all like to keep our network gear running during a power outage — trouble is, your standard consumer-grade uninterruptible power supply (UPS) tends to be overkill for routers and …read more Continue reading Open Source DC UPS Keeps the Low-Voltage Gear Going
Ceiling clocks were a bit of a thing back in the days when clock radios were a fixture of nightstands. The idea was to project the time onto the ceiling …read more Continue reading Don’t Look Up, or You’ll See the Time from This VFD Projection Clock
There’s no shortage of cheap digital oscilloscopes available today from the usual online retailers, but that doesn’t mean the appeal of building your own has gone away — especially when …read more Continue reading STM32 Offers Performance Gains for DIY Oscilloscope
[mircemk] had previously built a frequency counter using an Arduino, with a useful range up to 6 MHz. Now, they’ve implemented a new design on a far more powerful STM32 …read more Continue reading Simple STM32 Frequency Meter Handles Up To 30MHz With Ease
[tinfever] needed a high-power benchtop electronic load for an upcoming project, and by their own admission decided foolishly to build their own. And we’re glad they did. The thing is, …read more Continue reading Hackaday Prize 2023: 10 kW Electronic Load
Every once in a while we get wind of a project that we’re reluctant to write up for the simple reason that it looks too good to be true. Not …read more Continue reading Over-the-Top Programmable Resistor Looks the Part and Performs
[jgpeiro] is no slouch when it comes to building small, affordable oscilloscopes out of common microcontrollers. His most recent, based on an RP2040 with two channels that ran at 100 …read more Continue reading STM32 Oscilloscope Uses All the Features
While things like the Arduino platform certainly opened up the gates of microcontroller programming to a much wider audience, it can also be limiting in some ways. The Arduino IDE, …read more Continue reading Blinkenlights to Bootloader: A Guide to STM32 Development
