Description The LMR16006 is a PWM DC/DC buck (step-down) regulator. With a wide input range of 4 V to 60 V, it is suitable for a wide range of application from industrial to automotive for power conditioning from an unregulated source. The regulator’s standby current is 28 µA in ECO mode, which is suitable for

CAMdrive Hello! My project CamDrive is intended to be an open source multi-axis control for time-lapse photography. The current state of development can be traced in the CAM Drive project blog. CAM-Drive ProjektBlog Currently, there is an Android app that already can control one axis. For interested developers I uploaded the source code in my
Wearable technologies that incorporate physiological sensors are appearing on the market in so-called smart watches. Next generation monitoring devices will be worn on the body to monitor conditions such as blood glucose levels in near-real time and allow them to collect considerably more data over the course of a day. Initial examples of this novel

Two phone makers have announced products with octa-core ARM processors from Taiwanese chip firm MediaTek at IFA in Berlin, where AllWinner announced an octo-core processor this morning. Alcatel has used MT6592 which has eight ARM Cortex-A7s and an ARM Mali GPU in its Hero 2. The LTE modem is another MediaTek chip: the MT6290. Mali

This project is based on Maxim’s application note: Using a UART to Implement a 1-Wire Bus Master http://www.maximintegrated.com/app-notes/index.mvp/id/214 Resistors can vary from 200ohm to 20kohm. Transistors can be BJTs or MOSFETs. The diode used in the simplified version should be fast and has a low forwarding voltage. 1N4148 is known to work. A USB to

Most electronics projects require some common stuff like regulated power supply, input tact switches, and output LEDs during prototyping and testing phase. Wiring these things on a breadboard for every new project could be time consuming and boring. We introduce you the Basic Experimenter Board, a general purpose development tool that will not only reduce

We have a great Dutch Holiday tradition called sinterklaas (5th of december, this is what the US Santa is based on). For the older “non-believers” we make surprises. The purpose is to buy a small present but make a really cool “surprise” around it. Here my arduino based Split-flap game I made as surprise. I

Microsemi has announced a family of DSP chips. Called Timberwolf, it is described as a third-generation DSP architecture designed with a proprietary 4 MAC core, dedicated hardware accelerators, and two independent 16bit DACs in 64pin QFN and 56pin 3×3 CSP packages. “This field upgradable DSP platform, when combined with algorithmic firmware, can enable beam forming,
