Light Up Clock for Kids – Green Means Go! Red, Stay in BED!!!

We were going crazy without enough sleep!!! Our 2-year-old could not understand how to “wait for the 7” on the clock before coming out of his room morning after morning. He’d wake up early (I mean like 5:27am – “there’s a 7!!!” he’d say) and just assume time to get up, come out of his …

Steampunk Compass using Arduinio

Having built a few puzzle box games recently, and having some components left over I thought I would build a functional Steampunk Compass. Based around a Arduino Duemilanove this is a really quick and simple build. Taking reading from a digital compass the Arduino controls a servo to position a clock hand. Step 2: Connect …

ABUSED HARD DRIVE BECOMES POV CLOCK

We all know that there’s not much to do with an old hard drive. Once you render the platters unreadable and perhaps harvest those powerful magnets, there’s not much left of interest. Unless, of course, you turn the whole thing into a persistence-of-vision clock. At least that’s what [Leo] did when he created “PendoLux”. The clock …

Arduino Digital Clock Synchronized by the 60Hz Power Line

This Arduino based digital clock is synchronized by the 60Hz power line. It has a simple and inexpensive common anode 4 digit 7 segment display which shows hours and minutes. It uses a cross over detector to detect when the incoming 60Hz sine wave crosses the zero voltage point and derives a 60 Hz square …

3D Printed Alarm Clock Looks Just Like Store Bought

Clocks are a popular project on Hackaday. They’re a great way to showcase a whole range of creative build techniques, and can make an excellent showpiece as well. We’ve seen everything from the blinkiest binary build to the noisiest alarms, but [Benoit] has delivered something different — a stylish build that looks like it came …

Easily run your ATtiny at 16MHz, without an external clock, from the Arduino IDE

Hardware components: Atmel ATTiny85 × 1 SparkFun Tiny AVR Programmer × 1 Software apps and online services: Arduino IDE   STORY Introduction The Atmel tinyAVR MCU’s (ATtiny) are a series of chips optimized for applications requiring performance and/or power efficiency in a small package. These have internal clocks that runs at 8 MHz. They can also be clocked …
