ESP8266 Desktop Clock – WiFi Synchronised
https://www.electronics-lab.com/esp8266-desktop-clock-wifi-synchronised/
This project is a wifi synchronised desktop clock using 7-segment displays. The heart of the project is a ESP8266 board. The ESP8266 is a awesome chip; with integrated WiFi, 80MHz clock speed, total 160kb RAM, 512kb of flash memory, and a ton of other features, it makes a regular Arduino look like a joke. The […]
T-baneklokke – A Coundown clock
https://www.electronics-lab.com/t-baneklokke-coundown-clock/
Joakim made a coundown clock for his wife and documented the whole process on his blog: The clock is built using an Arduino, and has a battery powered real time clock to remember the time while powered off. To make it truly stand alone I added the possibility to set the time and time-to-leave using buttons. The […]
BIG Clock Made From Six 3″ 7-Segment LCDs
https://www.electronics-lab.com/big-clock-made-from-six-3%e2%80%b3-7-segment-lcds/
Pierre Muth build a nice big clock using 3″ 7-segment LCD displays. The clock is driven by a PIC18F87K90 and a few other components are used. He writes: We need clocks. Once you have passionate activities which absorbs all your attention, if you want to keep contact with the social society surrounding you, it’s crucial […]
ATtiny85 Ring Watch
https://www.electronics-lab.com/attiny85-ring-watch/
This is a great ATtiny85 watch that uses a SSD1306 OLED display and is powered by a CR1220 battery. Today core subject, ATtiny85. Someone suggest me to use SOIC version to reduce the watch size and I found the coin cell mAh calculation method will count the battery voltage down to 2.0 V, so this […]
OpenSource Arduino OLED Clock with temperature measurement
https://www.electronics-lab.com/opensource-arduino-oled-clock-with-temperature-measurement/
Konstantin Dimitrov has published his Arduino OLED clock which uses DS1307 real time clock module and TMP102 temperature sensor that communicate through I2C. This clock will not only show you exact time and date but also it will show you the ambient temperature in both Fahrenheit and Celsius, with accuracy of 0.5°C (-25°C to +85°C) and […]
MSP430 VFD Clock
https://www.electronics-lab.com/msp430-vfd-clock/
Daniel Johnson @ danielelectronics.com has build a VFD Tube Clock based on MSP430 microcontroller and explains it’s code. I wanted to do a follow-up to my last clock build, the MSP430 Analog Gauge Clock, reusing some of the code from that project, and I had an IV-18 vacuum florescent display (VFD) tube that I bought on […]
Wake-U-Up System
https://www.electronics-lab.com/wake-u-up-system/
Zhiyong Hao and Zhuo Chen from Cornell Univercity build A PIC-based Alarm clock system that is different from most alarm clocks known. This project is aimed to design a ‘Sleep and Wake-up Assistant’. Different from a normal alarm clocks which can only make noise, this alarm clock is designed to wake up a person in a comfortable […]
ATtiny OLED Watch Core
https://www.electronics-lab.com/attiny-watch-core/
陳亮 @ instructables.com shows us his ATtiny85 OLED display build on a breadboard: This instructable show how to use an ATtiny85 to create a tiny watch core that can run over 1 year before recharge or replace battery. The instruction to make the watch case may be in next instructable. I have made a few Arduino […]
Designing and Building a binary clock
https://www.electronics-lab.com/designing-and-building-a-binary-clock/
Parker Dillmann @ macrofab.com has designed a wrist LED binary clock based on PIC16F527 Microchip mcu. The Macro Watch stemmed from those constraints. I picked the PIC16F527 microcontroller by Microchip to be the core of the watch because it was the cheapest MCU I could find that had enough I/O and I knew at least […]
LCD clock with 4″ display
https://www.electronics-lab.com/lcd-clock-with-4-display/
mcs.uwsuper.edu has build a big LCD clock based on MSP430 mcu and DS3231 RTC clock chip. They write: The clock is built on a 4″ (101 mm) LCD displays OD-103 manufactured by Orient Display. The LCD provides high contrast of digits and easy reading from a large distance. The unit runs on batteries and can also […]
