When [Rodrigo Feliciano] realized that the reason his seven-segment LED wall clock wasn’t working was because the original TG1508D5V5 controller was fried, he had a decision to make. He could …read more Continue reading LED Wall Clock Gets Raspberry Pi Pico Upgrade
There’s a good chance you’ve seen “Nixie clocks” on the Internet that replace the classic cold cathode tubes with similarly sized LCD panels. The hook is that the LCDs can …read more Continue reading Recreating a Popular Faux-Nixie Clock
I built three NTP servers each with chrony, openntpd and NTPsec and one Ubuntu server that monitors NTP traffic:
Zeek and Suricata generate logs
Logs are sent to syslog.
Logstash reads logs from syslog and processes them.
Logstash sends p… Continue reading How to enhance protection in my NTP architecture against cyber attacks? [closed]
I am a beginner in cyber security and they asked me to build a secure architecture for time servers. I have 3 three NTP servers on Ubuntu, each configured with chrony, nptd, NTP (In order to test them and find out which of them is the fast… Continue reading How to Protect NTP Servers from Cyberattacks?

Smart phones have taken the place of a lot of different devices especially as they get more and more powerful. GPS, music and video player, email, and of course a …read more Continue reading Saving a Clock Radio with an LM8562
A great majority of hackers build a clock at some point. It’s a great way to get familiar with electronics and (often) microcontrollers, and you get to express some creativity …read more Continue reading Simple NTP Clock Uses Custom RGB 7-Segment Displays
I noticed some strange behaviour on my firewall WAN interface last night, and then later on my LAN interface as well.
There seems to be traffic to a known tor node 192.99.168.180 on port 123. I block all tor by default on my network, and I… Continue reading Traffic to Tor node NTP port [closed]
We all know the drill when it comes to online security — something you know, and something you have. But when the “something you have” is a two-factor token in …read more Continue reading Hackaday Prize 2023: Sleek Macro Pad Makes 2FA a Little Easier
Many of the clocks we feature here on Hackaday are entirely built from scratch, or perhaps reuse an unusual display type. But sometimes, an old clock is just perfect as …read more Continue reading Classic 1960s Flip Clock Gets NTP Makeover
