Data logger for Skiers

Posted on December 5, 2016 by R-B Leave a comment

Matthew Magaldi and Aidan Angus are both winter sport enthusiasts who love skiing. They designed a PIC32-based data logger system that captures their skiing experience on a SD card and also wrote a Python script for post-processing and visualization of their skiing behavior. The data logger receives data from multiple sensors, including an accelerometer, a gyroscope, and a temperature/pressure sensors. There were several tradeoffs for the hardware and software used in the project. First, in software, because we were limited to using a single core processor in the PIC32, we were limited in the synchronization of our data. The protothreads that

Virtual fireplace using Raspberry Pi

Jaret Burkett, a tinkerer from Texas, enjoys fireplace. But the warm weather of Texas won’t let him run the fireplace most time of the year. One day, he figured out he could simulate a burning fireplace with crackling fire sounds using a Raspberry Pi computer and his old TV that perfectly fit the fireplace. Check out his step-by-step instructions to setup one for your fireplace.

DIY IoT breathalyzer

Dominic Peters shares his project about making an IoT breathalyzer using ESP8266 on Hackster.io. It uses the MQ3 sensor for detecting alcohol concentration on your breath. The ESP8266 reads the sensor data and post it to Cayenne IoT platform so that the data can be recorded and viewed over time from anywhere via internet. The device needs to be portable and durable if it should be used while under the influence. The 11.1 Wh/hr lipo battery provides about 8 hours of continuous use. All the components are stuck to the battery pack with thick double sided tape. I hope this provides

OpenRC Tractor

OpenRC is an open source 3D printed RC tractor designed all from scratch. It is a 1/10 scale replica of an original Ebro 160D tractor, with RC electronics. I also prepared some basic instructions and BOM, so you can easily print and assemble your own tractor. It is designed to be easy to print and no supports are needed for any part. Points to bear in mind: As part of optional parts, you’ll find different optional plates. There is one for Spain and one for Sweden because there are already OpenRC tractors in both countries. If you print your tractor

Personal location tracker

Posted on December 1, 2016 by R-B Leave a comment

Tiobel‘s Track Me project describes a personal GPS tracker using an Arduino Mega along with a GPS module and a GPRS Shield. The GPS module finds its location using data from more than 3 satellites. In order to retrieve the location remotely, you need to call the number of the SIM card placed into the GPRS shield, and the system will send you back an SMS with the actual position and it’s link to the google maps.
