Conversation analysts consider turns to be the most basic unit of conversation. As you would imagine, the intricacies of turn-taking have been well documented by researchers, and this process always involves the careful transcription of pre-recorded conversation. I am no expert but wanted to develop a recording tool for my own personal research. Below you […]

Display with a good legibility even in non-optimal light conditions is always an advantage. When we add to it a significant simplification thanks to built-in character sets and graphic functions, we get a display of the eDIP a eDIP TFT series from company Electronic Assembly. Powerful command, touch panel and a high flexibility enable to
eDIP and eDIPTFT series intelligent displays speak many languages Continue Reading
Introduction Isolated DC/DC converters are required in a broad range of applications including power metering, industrial programmable logic controllers (PLCs), insulated-gate bipolar transistor (IGBT) driver power supplies, industrial fieldbus, and industrial automation. These converters often are used to provide galvanic isolation, improve safety, and enhance noise immunity. Moreover, they can be used to generate multiple

Step 1: To Begin The basis for Groover’s axis was the two mini stepper motors from the DVD-RW drives. The motors drive the DVD head mechanism which either moved the laser cutting head, or the cutting table. My first starting point was to find a similar set of motors, and a reclaimed laser diode. However

Experience Flow and Control Electronics Background We are making the participants refuel a dead nuclear engine. We are making them handle dying and charged nuclear fuel rods. We want to give them an experience which will stay with them for long. Participants get multisensory input in auditory, visual and haptic forms. The fuel rod is

Auto ranging ohmmeter using arduino. This article is about a simple auto ranging ohmmeter using arduino. The measured resistance is displayed using a 16×2 LCD display. The circuit is sufficiently accurate and uses minimum number of external components possible. Before going into the details of this project, lets have a look at the basic resistance

A switch input is one of the simplest interfaces to an MCU. However, when very low power designs are needed the pullup or pulldown resistor for the switch can draw a significant current. If the switch input is a momentary switch the current flow is very short so it is rarely significant. However, if the

The Color Matching Game! Posted on February 18, 2013 by Dillon Reisman Group Members: Sam Payne, Prerna Ramachandra, Dillon Reisman, Abbi Ward Early idea sketches: 1) Gummi-Bear RGB color-mixer! 3) The “Waker-Upper” Idea actually implemented: We built a color matching game. The computer will generate a random color, then the user must use a touch sensitive
