The Pixelduino is a tiny Arduino-compatible microcontroller with a full color 1.5″ OLED display + MicroSD built-in! About this project The Pixelduino is an Arduino-compatible microcontroller that features a 1.5″ 128×128 pixel color OLED screen and a MicroSD slot! There are all sorts of things you can do with a device like this. You can […]

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 […]
