Enix: The Modern Nixie Clock
https://www.electronics-lab.com/enix-modern-nixie-clock/
Here at electronics-lab.com we love Nixie clocks and when we came across this beautiful IN-14 clock we thought that worth sharing the news with you. This is a beautifully sleek product that gives new life to vintage components. Argon Prototypes Inc. has launched a kickstarter campaign and it is already funded with 19 days remaining. […]
NIMO Clock – Recreating the look of a 60’s CRT display
https://www.electronics-lab.com/nimo-clock-recreating-the-look-of-a-60s-crt-display/
Recreating the look of a 60’s CRT display with small LCDs. By Paul Bricmont @ hackster.io: My design uses six 1.44-inch TFT LCD displays to display NIMO-style digits. These small LCD displays are cheap (around $3.50 US each) and use the ST7735 chipset and SPI bus. To drive the displays I’m using the Adafruit Metro […]
ESP8266 LED Matrix Clock
https://www.electronics-lab.com/esp8266-led-matrix-clock/
Simple LED matrix Clock based on the popular ESP8266 with Real Time Clock module and time synchronization over WiFi from an NTP server. One note on the RTC module, apparently it also has the ability to charge the battery, however that’s not a good idea when using a CR2032. One possible solution would be to […]
ATtiny85 20MHz Internal Clock
https://www.electronics-lab.com/attiny85-20mhz-internal-clock/
Here is a new tutorial from technoblogy.com on how to run ATtiny85 with internal 20MHz clock. The ATtiny85 is rated at a maximum clock speed of 20MHz at 4.5 – 5.5V. For some applications it would be nice to get the maximum speed without needing to buy a 20MHz crystal, or tie up two I/O […]
Arduino Real Time Clock with Temperature Monitor
https://www.electronics-lab.com/arduino-real-time-clock-temperature-monitor/
Hi guys, in one of our previous tutorials, we built a real-time clock with temperature monitor using the DS3231 and the 16×2 LCD display shield. Today, we will build an upgrade to that project by replacing the 16×2 LCD display with an ST7735 based 1.8″ colored TFT display. Apart from changing the display, we will […]
ATtiny85 runs at 0.000011574Hz clock
https://www.electronics-lab.com/attiny85-runs-0-000011574hz-clock/
What is the lowest possible clock frequency at which a microcontroller can still do useful work? Here’s a little project that attempts to explore this weird question. by igendel @ idogendel.com: ATtiny85 runs at 0.000011574Hz clock – [Link]
Arduino Real Time Clock with DS1302 and Nokia 5110 LCD Display
https://www.electronics-lab.com/arduino-real-time-clock-ds1302-nokia-5110-lcd-display/
Hi guys, in one of our previous tutorials, we made a real time clock, using the DS3231 RTC Module and the 1602 LCD display module. For this tutorial, we will be building something similar using the DS1302 RTC module and the Nokia 5110 display module. Unlike the 1602 LCD module which was used in the […]
Real Time Clock and Temperature Monitor using DS3231 Module
https://www.electronics-lab.com/real-time-clock-temperature-monitor-using-ds3231-module/
The DS3231 is a very low power RTC chip, it has the ability to keep time with incredible accuracy such that even after power has been disconnected from your product, it can run for years on a connected coin cell battery. This module has the ability to communicate via I2C or SPI but for this […]
ESP32 NTP OLED clock
https://www.electronics-lab.com/esp32-ntp-oled-clock/
danman @ blog.danman.eu build a OLED display NTP clock and document his process on his blog: As a first project with my new ESP32 module with OLED display I chose to build OLED clock. I thought I’ll just find some existing code, upload it and it’s done. There are a few such projects for ESP8266 […]
Solr: Digital Wrist Watch Calculates time from Sun Position
https://www.electronics-lab.com/solr-digital-wrist-watch-calculates-time-sun-position/
Time can be calculated using the azimuth of the sun (aka solar time). Based on this idea, Tinkerman has built an unusual project called Solr. The concept is to translate the position of the sun into time presented on a vintage display. This new digital watch is freak enough to work only with a battery […]
