About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a “this accessory may not be supported” message appeared on-screen; when I unplugged and re-plugged the iPhone to the charger, it didn’t reappear, so I didn’t think […]

A growing branch of robotics research is the study of swarm organization, emergent behavior and artificial intelligence through the use of autonomous robotic agents. In this Instructable, I’m going to walk you through a one week project that I created as part of my Masters Architecture studies at theCalifornia College of Arts in collaboration with Prerna Auplish.

Alexa controlled timers at a glimpse. A really fancy egg-timer with added temperature control. Story Idea Both of us like to tinker with electronics and the latest hard- and software. While most projects never get out of “early-Alpha”, we wanted to create something with a prototype look&feel for quite a while now. Participating in The

A project using the AmazonDRS library for WiFi101 connected Arduinos. Just like the AWS IoT button, but completely open source! Things used in this project Story TL;DR; Buy some stuff on Amazon by clicking a pushbutton connected to your WiFi101 enabled Arduino. It’s like a Dash button, but cooler! Motivation Back in the Spring of

Pulse sensors have become popular due to their use in health-monitors like the Fitbit. The sensors used are cheap, simple and pretty reliable at getting a reasonable indication of heart rate in daily use. They work by sensing the change in light absorption or reflection by blood as it pulses through your arteries — a technique

The AFBR – S50 is a multipixel distance and motion measurement sensor. It has an integrated 850nm vertical cavity surface emitting laser (VCSEL) which uses a single voltage supply of 5V. It’s measurement rates are quick and as fast as 3 kHz, which is a distinguishing feature. However, this is not the reason why the

Introduction A data logger is an electronic device or instrument that records data over a period of time. It allows the user to record time or location stamped data which can be viewed at a later time or real time. Irrespective of the type of data being logged or the kind of data logger, these devices usually
