This tiny step-down converter chip measuring just 2.5 x 2.0 x 1.0 mm contains an integrated coil and can handle an output current up to 1 A. The XCL210/XCL220 are a new family of step-down micro DC/DC converters which have been specifically designed to minimize unwanted EMI emissions. This makes them particularly suited for use in small-scale RF applications. The design […]

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
