This is a fun project that can be done easily and also cheaply. In this instructable we will explain step by step how to make this beautiful POV clock. Used material: Arduino Uno, RTC modul, ULN 2003, IR diode and IR transistor (used like a sensor, more details in next steps) 4 pushbuttons (for controling […]

This is a relatively simple clock to build, in terms of the hardware required and in terms of hooking up all the wires. The complexity lies in the software, which I’ve conveniently included as part of this instructable 🙂 This instructable illustrates a few things: * Keeping relatively accurate time on an Arduino without using

One day while exploring the bric-a-brac at the markets, I stumbled across an old, Bakelite slave dial from the 1950’s. Slave Dials are clock movements without the actual time keeping circuit. All they contain is the mechanism to drive the hour and minute hands, which can be advanced by an electric pulse. This pulse is

Pinoco was hit with the holiday rush, so it took a few extra weeks to get my new batch of laser cut acrylic. I nailed it this time. Right away I could tell the engraving was perfect. I even spaced out the holes for the speaker just a hair. The holes on the last one

Numitrons are neat display devices similar to nixie tubes but designed for much lower voltages. Numitrons are basically incandescent displays in which filaments create the segments. They have a retro look that I liked so much. I bought 6x IV-9 Russian Numitrons in eBay, they were about 3$ each, they’re pretty cheap! At that time

Here you will find complete construction details including circuit diagrams, PCB layouts and PIC firmware (and the source code). The code was written in Proton PIC BASIC but the good news is that there is now a free version of this compiler available for download; AMICUS18. ** UPDATED 30th June 2016 ** There is an

our modern era, digital logic has become the core of all the electronics circuits either in the form of an FPGA, microcontroller, microprocessor, or discreet logic. Digital systems use many components that must be interconnected to perform the required functions. The vital element for proper operation of such a digital system is a CLOCK signal

In this tutorial, the Arduino displays the time and date on a LCD (optional) and in the Arduino IDE serial monitor window. A PCF8563 real time clock (RTC) IC is used to generate the time and date. The time and date can be set using the Arduino serial monitor window. An optional battery can be

Ever since I discovered nixies I wanted to make a clock with them, but all the designs I found were for 4 or more nixies, required a custom power supply and a complicated driving system. As the cheap guy I am, I didn’t want to buy lots of nixies or components to make such complicated

The most popular RTC for the Arduino is the DS1307. However, it does have some drawbacks, the most notable of which is that its operating voltage is 5v, which means it cannot be used with 3.3v projects. The Maxim DS1339 however, features a wide tolerance of voltages from 2.97V-5.5V with the typical voltage as 3.3v,
