Since this book was written, Arduino 1.0 was released and Google has changed the Open Accessory standard a lot. At the start of December 2011 Arduino 1.0 was released. This changed a few things, requiring all third-party libraries to be updated. This hasn’t happened yet for the Android Open Accessory ADK. So until this is […]

The Team Kaitlin Schaer as scribe; Bryan Gardiner as tutor; Ruben Markowitz as designer; Anna Failla as integrator Introduction In a time where the logistics of sleep can be all too much to handle, there is a solution! There is a smarter pillow, a pillow that will wake you up just when you need to get […]

Why make your own printed circuit boards when you can get them commercially made for low cost? For one, it can take one to four weeks to receive the boards. For prototyping, this can be a major hurdle. Each design iteration will then take a month or more, and a project may need many months […]

In all my arduino projects I was using cheap 1602 LCDs mostly because… they are cheap but also of the libraries flexibility.  Recently I found a nice TFT 1.8 inch 128×160 in a very competitive price and i thought to give it a go.  Just $4.5. I had a little bit of trouble to make […]

HRL Laboratories, based in Malibu, CA, recently tested a prototype neuromorphic chip with 576 silicon neurons aboard a tiny drone measuring 6×6×1.5 inches and weighing 93 grams. The project was funded by the Defense Advanced Research Projects Agency (DARPA). The drone, custom built for the test by AeroVironment of Monrovia, CA, flew between three separate […]

Subject: Daily life activities of food preparation can be challenging for consumers due to restricted skills and experience, loss of perceptive abilities (accident/aging) or due to product fraud and contaminations, commonly summarized under the term of food adulteration, which are exceeding human perceptive abilities in general. Thus, in our work the E-Taster-assistance-system for living assistance […]

Introduction This is the second article in a three part series I am writing on the Arduino hardware platform. This article focuses on wiring an Arduino to a character LCD and a graphic LCD, and includes static and animated demos to show off the capabilities of each display. Character and Graphic LCDs After I initially […]

This tutorial back-to-basics video discusses the operating point (or quiescent point, Q-point, bias point, etc.) of a bipolar transistor (BJT) circuit, and how the choice of the circuit design can affect how sensitive the bias point will be to the value of Beta (current gain) of the transistor. Ideally, you’d want to use a circuit […]

Hello everybody, I’ve been working on a midi controller for some time now, Midi OUT hasn’t been a problem, but for Midi IN i had to take some more time. i’ve used this circuit for midi input but i’ve used a 4n25: original thread @ http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1187962258/ it works great! but for my project i need […]
