If there’s no circuitry on a printed circuit board, does it cease being a “PCB” and perhaps instead become just a “PB”? Call them what you will, the fact that …read more Continue reading Circuit-less PCB Featured as Faceplate for a Digital Clock
[Jeff Geerling] has been following the various open source time projects for some time now, and is finally able to demonstrate a working and affordable solution for nanoseconds-accurate timekeeping in …read more Continue reading Stratum 1 Grandmaster Time Server on a Budget
Network Time Protocol (NTP) is one of the best ways to keep networked computers synchronized to the same time. It’s simple, lightweight, and not only allows computers to maintain a …read more Continue reading Network Time Protocol on the ESP32
They say time is money, but if that’s true, money must also be time. It’s all figurative, of course, but in the case of this NTP server heater powered by …read more Continue reading Bitcoin Mining ASICs Repurposed to Keep NTP Server on Track
Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum …read more Continue reading NTP, Rust, and Arduino Make a Phenomenal Frequency Counter
Most Hackaday readers will be familiar with the idea of a network time server; a magical box nestled away in some distant data center that runs the Network Time Protocol …read more Continue reading Portable GPS Time Server Powered by the ESP8266
LEDs have become so ubiquitous in our projects that just hearing that term probably conjures images of tiny illuminated domes in an array of single-spectrum colors. It’s easy to forget …read more Continue reading A Custom Clock with LED Filament Hands
We’re always fans of interesting clock builds around here, whether it’s a word clock, marble clock, or in this case a clock using a unique display method. Of course, since …read more Continue reading Using Heaters to Display Time
I recently tested the NTP Time Synchronization Attack as desribed and demonstrated by Jose Selvi in 2015.
Basically, the attack was mostly used to send the victim’s clock in the future, so the already cached HTTP Strict Transport Security … Continue reading How did ntpd got pacthed to prevent NTP time synchronization attacks?
Building a clock of some sorts seems to be a time honored tradition for hackers and LED clocks seem one of the most popular. You can build anything from a seven-segment display to a binary clock or something even more …read more
