Motion Control Rig for Time-Lapse Photography

Tyler Winegarner and Chris Bordeleau have posted great instructions on their build of Arduino-based motion control rig for time-lapse photography on Makezine Weekend Project section. If you dig around in your camera’s settings long enough, you’re almost assured to find that it has a mode to create time-lapse videos — those magical, time compressing movies that can turn any hillside or street corner into a lightning-paced dreamscape. Time-lapse videos by themselves are easy enough to make, but if you do enough of them, you’re likely to get bored with the motionless camera framing. But what can you do here? Having

DIY Arduino Pedometer Wristwatch

Benhur.Goncalves shared his design of an Arduino-based Wristwatch that features Pedometer along with Temperature, Altitude and Compass sensors. Hi folks! Last few days I’ve been obsessed with the idea to make my own watch from arduino parts, but something cool I could use and say I did it myself. So I found out there was a sensor board (commonly named GY-87) which had three sensors on it: HMC5883L (compass), BMP085 (pressure, altitude, temperature) and MPU6050 (accelerometer and gyroscope). With it, via I2C, I could add an Arduino Pro Mini, and an I2C Oled Display and make a watch capable of

TAHMO to deploy a network of 20,000 weather stations in sub-Saharan Africa

Team TAHMO is planning to build a network of 20,000 weather stations throughout sub-Saharan Africa for better weather forecasts, early warnings, and climate observations, which will eventually lead to improved food production in Africa. TAHMO stands for “Trans-African Hydro-Meteorological Observatory”, a program that aims to design, build, deploy, and operate a network 20,000 weather stations in sub-Saharan Africa (www.tahmo.org). Presently, we have pilot stations in Senegal, Chad, Nigeria, Uganda, and South Africa and “pilots at scale” in Ghana and Kenya. TAHMO stations have to be be affordable and robust. For example, unlike standard weather stations, there should not be any moving

Raspberry Pi Bandwidth Monitor

Archie500 has posted instructions about how he built a Raspberry Pi-based monitor for his internet bandwidth into and out of his house. This is a bandwidth monitor using a Raspberry Pi and an OLED display to graphically show the internet bandwidth into and out of our house. A video showing it working is above. Sometimes if the internet is slow or not working very well it can be hard to tell if it’s because three other people are watching YouTube videos of if there’s some other problem with the internet connection. By checking the bandwidth monitor you can see straight
