The inspiration for this project was the dreadfully painful waking up process in the morning. And now that school is starting back up I had to get off of the summer schedule where you could get away with not waking up at the crack of dawn. Often times I’d find myself snoozing my alarm clock […]
An Alarm Clock (but It Is Harder to Turn Off) Read More »
I got this idea for a while but I never had the chance to try it out. Friday, a workmate gave me a LCD shield for Arduino and I thought that was the right time to build a clock that comunicate the time through QR-codes. Of course, it’s extremely useless (as most of the clocks nowadays). In the

Reaction time is a measure of time a person takes to identify a stimulus and produce a response. For example an athlete’s audio reaction time is time elapsed between firing of gun shot (that starts the race) and him or her starting the race. Reaction time plays an important role in situations of immediate response

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

Know someone that constantly struggle to get out of bed, comes late to work and you are just want to give them a nudge in the morning. Now you can make your own Hey Pillow. Inside the pillow is embedded with an annoying piezo buzzer that you can control via your phone, so that you

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

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

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

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

In this project, we will learn the basics of User Datagram Protocol (UDP). We will request and receive time from the NTP server using the above communication protocol. The 4Duino display is utilised to print the received time in both, digital and analogue clock format. Transfer of Data over Internet The 2 most common ways
