Building a Raspberry Pi stratum 1 NTP server
So this article is going to be my notes on how I built one using a cheap GPS module off eBay as the reference time source and a Raspberry Pi. (a 2B in this case, but hopefully the differences for newer models will be minor; if there are any, they’re probably around the behavior…

Cat Food Access Control
This project goes over the process I used to create an automated cat food bowl, for my elderly diabetic cat Chaz. See, he needs to eat breakfast before he can get his insulin, but I often forget to pick up his food dish before I go to bed, which spoils his appetite and throws off…

Getting Date & Time From NTP Server With ESP8266 NodeMCU
Every once in a while you’ll come across an idea where keeping time a prime concern. For example, imagine a relay that has to be activated at a certain time or a data logger that has to store values at precise intervals. The first thing that comes in your mind is to use…

Network Time Digital Clock Using the ESP8266
https://youtu.be/3LkKYtQqzKo Sometimes clocks lose their time and you have to set up it again. If you don’t want to get bored any more make your own digital clock! It uses a wemos D1 board which gets data from an ntp(network time protocol) server and shows time on an OLED lcd. Don’t miss it! …
