Simple NTP clock using USB display module

Dilshan Jayakody writes: Simple NTP clock is a maintenance-free clock application developed to work on single-board computers like Raspberry Pi, Orange Pi, etc. This clock application uses the Simple Network Time Protocol (SNTP) to get the time and display it on seven segment display which I designed.  This application is designed to work on most of […]

Simple digital clock with PIC16F628A and DS1307 and 7-segment LED display

A simple digital clock with PIC16F628A + DS1307: In this new project I am again using PIC16F628A microcontroller. The goal is simple digital clock with 7-segment LED display and the clock will have no additional functionality – no alarm, no seconds digits, no date. The latter can be added in the software though. For the […]

WiFiChron alarm clock

Here’s a cool WiFiChron clock with 8-character alphanumeric LED display by Florinc: For WiFiChron, two cascaded modules make an 8-character display functionally similar to HDSP-2534, but bigger and more visible. With the “Display Abstraction Layer” already in place, software support should be easy to integrate, since controlling it with the HT16K33 breakout allows the re-use of […]

Adjusting clock with alarm, hygrometer & thermometer on 1.8″ ST7735 display

Nicu Florica blogged about his adjusting clock with alarm, hygrometer and thermometer on 1.8″ ST7735 display: I use feature from article Another adjusting clock with alarm & thermometer using DS3231 on 1.8″ ST7735 display and change reading internal temperature of DS3231 with DHT22 senzor (AM2302), but you can use a cheaper and not very precise DHT11 […]

Yet another Arduino clock

Sverre Holm blogged about his Arduino clock project: Its main features are: Controlled by a GPS module outputting data over an RS232 serial interface, and handled with the TinyGPS++ library Shows raw GPS data such as UTC time and date, position, altitude, and number of satellitess Shows derived GPS data such as 6-digit locator Finds local […]

Linux alarm clock

Benoit Frigon wrote an article detailing his alarm clock running Linux project, that is available on github: This is the display i made for my alarm clock project. The first version was a 24×7 LED matrix but later changed the design for a four digits seven segment display. I decided to keep the drawings for […]

MSP430 VFD clock – Manhattan style

Daniel has a nice write-up about building his Manhattan style VFD Clock based on the MSP430G2553 microcontroller and the MAX6921: I know that and IV-18 based clock isn’t anything original. In fact, Adafruit used to sell a kit for this exact purpose. I don’t really care that it’s not original, because all vacuum tubes are […]

PIC24 bedside table alarm clock

Markus Gritsch posted pictures of his PIC24 bedside table alarm clock in the project log forum: Another year, another clock, but for the first time for my alarm clocks. I am not using an MSP430 but a PIC24 instead. Standby current is with 5.5 µA only slightly higher than that of my MSP430 based ones. Time keeping is […]

Open source binary wristwatch

Jordan aka njneer made this cool binary watch project, that is available at Github: I’m pretty proud of this project; the clasp is a ribbon cable that doubles as the programming interface for the PIC microcontroller that drives everything. The time is displayed with superbright LEDs that are blinding at 15 mA, which means that I’m able to […]
