OK, I know that sounds weird, but bear with me for a moment.  My Pops really enjoys two things; 1) channel surfing and 2) farting. So one day I was over at http://hackaday.com/ and read about a guy who used his Arduino to turn a TV on and off with one of those brainwave reading […]

After having an entire month of dormancy on this blog, I’m finally beginning to cross off the blog posts on my “Pending” list. Last year, I made a blog post talking about Kentli’s lithium-ion based AA battery that has an internal 1.5 volt regulator. The first order never arrived, and the second one had arrived […]

The Haptic Proximity Module (HPM) seeks to enable people with low vision, or other vision impairments, to engage with their direct surroundings through vibration feedback from a range detector, and do so cheaply with readily available components. The aim of this instructables is to share the parts and process of creating this device in the […]

We are happy to announce the upcoming Josef Prusa’s and Alessandro Ranellucci’s workshop @ Officine Arduino / Fablab Torino, on February 16th and 17th. This two days workshop will cover the making & fine-tuning of the latest Prusa I3 with Prusa nozzle AND Ranellucci’s how-to slic3r lesson on Sunday. If you ever want to jump on the reprap […]

This is a quick guide with a bit of extra info (pin configurations etc..) that I’ve learnt along the way on how to use the L293D with the Arduino, showing that we can: A) Use a supplemental power source to power the DC motor B) Use the L293D chip to drive the motor C) Use […]

I am new to Arduino and wanted a project which would teach me different things. This got me involved with sound and the use of a LCD. This project is based on the Instructable posted by bertus52x11 which you can find here http://www.instructables.com/id/After-Dinner-Reaction-Time-Tester/ .  While I did start with the bertus52x11 project I did make […]

By Stephen Evanczuk Contributed By Hearst Electronic Products 2014-12-17 For rapidly growing markets such as wearables or the Internet of Things (IoT), energy harvesting can significantly enhance battery life—or even enable battery-free designs. At the same time, however, engineers designing wearables and IoT devices face significant constraints in total design size and footprint. To meet […]

Does it happen to you to slide your finger across your phone’s screen and turn the alarm off … just because you have automated this task and don’t even need to open your eyes? Well, let me present to you the alarm clock that WILL MAKE YOU: ….. stand from the bed ….. open your […]

Rather than use the USB to power my Arduino board with a handy trip to the electronics store with some more knowledgeable people than I, I have constructed a 9Volt DC power supply. Taking a 9 volt battery, a 9v battery holder and a 2.1mm coaxial DC jack (positive tip) I have quickly soldered a […]

Wouldn’t it be ideal if you could just press ‘print’ to produce a printed circuit board? In a paper titled ‘Instant Inkjet Circuits: Lab-Based Inkjet Printing To Support Rapid Prototyping Of Ubicomp Devices’ researchers Yoshihiro Kawahara of the University of Tokyo, Steve Hodges of Microsoft Research and Benjamin Cook, Cheng Zhang and Gregory Abowd of […]
