This is a giant digital clock, featuring four large LED displays that provide the time in a format you can read from the other side of the room. by David Johnson-Davies: This clock was inspired by some 2.3" one-digit 7-segment displays I saw on AliExpress [1]. I decided it would be fun...

Ken Shirriff published an interesting article on his blog. He writes: We recently obtained a clock that flew on a Soyuz space mission.1 The clock, manufactured in 1984, contains over 100 integrated circuits on ten circuit boards. Why is the clock so complicated? In this blog post, I...

GreatScottLab @ instructables.com shows us how to build an Arduino Nano based Nixie clock that features DS1307 RTC clock and 4x IN-14 Nixie tubes. He writes: In this project I will show you how to create a retro nixie clock. That means I will show you how you can control nixie tubes...

David Johnson-Davies published another great mini project. It's a Timer based on ATtiny402 and was build to demonstrate the low power sleep mode of the microcontroller. This article describes how to use the new 0-series and 1-series ATtiny microcontrollers in low-power projects, taking...

Dilshan Jayakody published a new mini circuit. He writes: The 1750Hz tone bursts are often used to trigger repeaters. There are several methods to build 1750Hz tone generators which including TC5082 divider, using MCUs, etc. In this post, I present another 1750Hz tone generator which I...

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...

wouterdevinck @ instructables.com writes: There are a lot of nixie clocks out there and a lot of them are based on the IN-14 tubes. I wanted to design my own for the sake of designing my own, but also had some specific requirements: Make it as small and thin as possible. A lot of the...

The projects shown here is a 2 Digit 00-99 Seconds or 00-99 Minutes Countdown kitchen timer based on PIC16F1825 micro-controller. The timer is useful in various applications like Cooking, Sports, Industrial, Sleeping. On board switches provided to set the time and start, a jumper to...
