Shawon Shahryiar’s second post of the XMega series is about the clock system, he writes: There are several clock sources that XMega micros can use as clock. These are both internal and external clock sources. As stated earlier, clocks are not set by fuse settings unlike traditional Mega AVRs, they are controlled by software and the […]

Arduino clock generator + divider experiment
John Slee writes: Anyway, I decided to try to make my own clock divider. Didn’t take long to get something working, and you can see the results in the video above. The genuine Arduino Uno is generating a simple square wave on pin 13, which you can observe with the built-in LED. The Freetronics clone […]
Mechanical ball clock
In this video Turnvater Janosch demonstrates his homemade mechanical ball clock: The clock runs for 12 hours, driven by a weight of 2.5 kg sinking approx. 1 meter during that time..Every minute a marble is lifted up and goes down a marble run with three flipping traps that count marbles for minutes, five-minute-steps and hours. The timekeeping […]
LCD clock version 2 – part II
Here’s an update on Kevin Rye’s LCD clock we covered previously. Source files are available here, for direct download LCD-Clock-V2-Source.zip: Once all the components and headers were soldered in, I attached my Arduino and configured it as an ISP. I then burned the bootloader for an Arduino Uno. I then connected my FTDI programmer and uploaded the blink […]
LCD clock version 2 – part I
Kevin Rye posted an update on his LCD clock project: Now that I’ve spent some time working with SMD Atmegas, I decided to redo the PCB to make it all SMD. By moving the Atmega to the SMD version, I picked up some additional space on the PCB. That allowed me to add a 4th button […]
DIY acrylic skeleton clock
Benmurton posted a step by step guide of his DIY acrylic skeleton clock build: This is a clock made fully out of acrylic! This was originally was my year 13 mechanical engineering college project, we had to research, design and build a project for a stakeholder, this including lots of recording so there is no shortage of photos. […]
A small GPS Arduino watch/clock
Here’s Oscar Liang another Arduino GPS project, he writes: Garlow stands for GPS Arduino Rechargeable Logger OLED Watch. The device gives GPS information which is logged on SD card and shown on a OLED display. It can be carried as a watch or simply used as a GPS data logger. The whole system is based on Arduino […]
Clock with retro display
Marcus Linderoth built a clock using a TI MSP430g2553 microcontroller and a HPDL-1414 display, that is available at Github: After having ported Contiki to the Launchpad, I was eager on doing something with it. I built this simple clock with a vintage HPDL-1414 “smart four-character 16-segment alphanumeric” display and a msp430g2553. Check out the video after […]
Nixie bargraph clock
Thereisonlyme wrote this Instructable detailing the build of his Nixie bargraph clock: This is a cool Nixie Bargraph Clock that has an hour and minute tube, the heights of the plasma in each tube indicates the time. There are some wires wrapped around the tubes so you can easily see what time it is without estimating. The […]
DIY digital desk clock with temperature display -part 1
A digital desk clock with temperature display feature by Electro-Labs: The brain of the circuit is a Microchip PIC18F252 microcontroller. It acquires precise time information from DS1307 real time clock via I2C interface and displays it on four digit 38 mm seven-segment display with the help of MAX7219CNG display driver. The temperature data is read […]
Add functions to your Dotklok: Remote control
Boris Landoni from Open Electronics writes about the Dotklok’s new feature, the addition of a remote control. We wrote about it previously here: The latest variation is the addition of a remote control, implemented with a few lines of code. This function allows you to read the signals sent by the common IR remote control used in TV, […]
Time plotting clock
A clock that plots time: The Time Plotting Clock mechanism is fantastically simple, 3 tiny servo motors allow the erasable marker to be moved along the drawing surface and raised when no contact with the surface is desired. This allows the pen to write the time. There is also a tiny eraser located in the […]
Mini 7-Segment clock V2, part II
Kevin Rye writes about his Mini 7-Segment clock V2 project, we wrote about it previously: Now for the moment of truth. I crossed my fingers and connected a battery pack. Woo hoo! It works! I love that feeling you get when you spend weeks working on a project, it all comes together in the end and it […]
Vacuum fluorescent display alarm clock
Vacuum fluorescent display alarm clock by Andrew Rossignol: I have been working on this fun little project for the last couple of days. I ordered this VFD display from Noritake as a free sample. I am quite grateful for their generosity and I decided to put this display to good use. I have written a driver […]
Digital clock using 7 segment display controlled using TV remote
Zxlee wrote a post on his blog detailing his digital clock on 7 segment controlled with TV remote: When the Arduino first power up, it will display time information on 7 segment displays. Besides that, the LCD will display the time, date, temperature and day of week information. Basically, this is the main part of the program. The program […]
RGB LED ring clock
Greeeg over at the 430h forum has been working on a RGB LED ring clock: The clock is comprised of 2 rings of 60 LEDs each. the LEDs are WS2812 parts, which include a built-in driver. The PCB is one of the interesting parts of this clock. I designed the board in altium as a single 6 […]
Alarm clock using an OLED
Markus Gritsch writes: Inspired by this and this wrist watch, I decided to build yet another iteration of my bedside table alarm clock, this time using an OLED. As a first step I made a handy breakout board for an 1.3″ 128×64 OLED. The rest is soldered together on a perfboard. The hardware is complete and […]
VFD clock with SNMP and NTP
VFD clock with SNMP and NTP by Pyrofer: It sets itself via NTP and adjusts for daylight savings time so no buttons and it never needs adjusting. It can be monitored via SNMP for logging the temperature and checking system uptime. The entire SNTP stack was written from scratch and it all fits in one […]
Purpleheart ornamental clock
Wardy wrote a post on his blog detailing his ornamental clock build: I wanted to use my new Adafruit Neopixel Ring to build an ornamental clock, using this interesting woodworking technique. Plus I figured that my milling machine might make this a feasible prospect. Milling, in my very limited self-taught experience, is best done using a material […]
GPS clock prototyping, Part II
Kevin Rye posted an update on his GPS clock project we covered previously: It’s been a few months since I worked on the GPS clock. I couldn’t nail down exactly how I wanted it to work. I had a few ideas floating around, as well as a list of what features I wanted to include. However, in order […]
