About this project Reasoning about time by printing onto the surface of a river Maybe you know situations when time’s running up. In German there is a metaphor for that and translated it would be something like “time trickles away“. Having this saying in mind and thinking of how to ‘imagine’ time the following idea […]

Raspberry Pi teams up with an Arduino
The principal behind ArduinoPi First a little clarification, the ArduinoPi isn’t really a library or a command set or an out of the box controller, its more a proof of concept using already know programming languages. If you want to use it be ready for some PHP, CSS, HTML, C++ and jQuery! The principal is […]
Cracking an electronic safe using brute force
Preface There’s nothing nefarious here, nor is the information contained herein particularly helpful to thieves or the dishonest. A thief would just cut the dang thing open and be done with it. The story So I bought a fire safe to protect some documents that I wanted protected in the unlikely event of a house […]
Drawing with a Laser – Hack-a-Day Logo
Reading Hack a Day I found an interesting challenge: drawing their logo somewhere. And the fact that was even more interesting: “preference will be given to the largest and smallest submissions“. I started figuring out how to do something like that with the things I had around, and settled for using a laser and two servos. Even though […]
Arduino Astronomical Clock
This product allows you to set separate turn-on and turn-off times and those repeat every day. The disadvantage of this product is that, as the seasons change, you need to constantly adjust the turn-on and turn-off times. As illustrated in Figure 1, the variation over the year (in sunset time in this example) is very […]
Bike Across the Country While in Your Basement
About this project This is a very simple and easy-to-build project that provides a sensor on the pedal crank of any exercise bike and generates keyboard output triggering Google Maps Street View to advance via the up arrow key. In my design, you pedal the crank five times, and then the Street View receives an up-arrow command […]
Arduino Based Distance Measurement using Ultrasonic Sensor
Ultrasonic sensors are great tools to measure distance without actual contact and used at several places like water level measurement, distance measurement etc. This is an efficient way to measure small distances precisely. In this project we have used an Ultrasonic Sensor to determine the distance of an obstacle from the sensor. Basic principal of ultrasonic distance measurement is based on […]
LPG Leakage Detector using Arduino
While LPG is an essential need of every household, its leakage could lead to a disaster. To alert on LPG leakage and prevent any mishappening there are various products to detect the leakage. Here we have developed an Arduino based LPG gas detector alarm. If gas leakage occurs, this system detects it and makes an alert […]
Live Temperature and Humidity Monitoring over Internet using Arduino and ThingSpeak
Humidity and Temperature are very common parameters for measuring at many places like farm, green house, medical, industries home and offices. We have already covered Humidity and Temperature Measurement using Arduino and displayed the data on LCD. In this IoT project we are going to Monitor Humidity and Temperature over the internet using ThingSpeak where we will show […]
Arduino Based Digital Thermometer
Thermometers are useful apparatus being used since long time for temperature measurement. In this project we have made an Arduino based digital thermometer to display the current ambient temperature and temperature changes on a LCD unit in real time . It can be deployed in houses, offices, industries etc. to measure the temperature. This project is based on Arduino […]
