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,
The OPT3001 is a sensor that measures the intensity of visible light. The spectral response of the sensor tightly matches the photopic response of the human eye and includes significant infrared rejection. The OPT3001 is a single-chip lux meter, measuring the intensity of light as visible by the human eye. The precision spectral response and
Silicon Labs introduced a new family of high-precision temperature sensors offering industry-leading power efficiency. Silicon Labs’ ultra-low-power Si705x temperature sensors consume only 195 nA (typical average current) when sampled once per second, which minimizes self-heating and enables multi-year coin cell battery operation. Unlike traditional digital temperature sensors, the Si705x devices maintain their accuracy across the
LED Engin has announced a quad die infra-red LED emitting 4.5W of flux, from 850nm and 940nm variants. “The four die parts are the world’s most powerful IR emitters,” said the firm, which has also released some deep red emitters. Called LZ4, the IR LEDs have a 7x7mm footprint and the firm’s dual-junction emitters. Heat
SAN FRANCISCO and MINNEAPOLIS, January 26, 2015 — Punch Through Design, a hardware and software development firm that brings Bluetooth Low Energy hacking to the masses, has released the Windows Bean Loader, the first-ever wireless Arduino programming app for Windows users. Using the loader app, Windows-based developers and hobbyists can easily upload code to their

NAND process geometries have become as problematic as logic process geometries with the advantages of further scaling – especially as 3D NAND approaches – being questioned. NAND process geometry is currently at 20nm and should be 10-20nm in 2017, says IC Insights adding “reported minimum feature sizes and mass production definitions are very imprecise and
Compact installation step relays Finder 26 series save energy similarly like latching relays, but they also operate on AC voltage. Step relays are able to effectively control lighting or other devices and they significantly simplify circuit complexity at the same time. If you´re familiar with a bistable (latching) relay, then you know, that a relay
With a step relay Finder 26 can be saved energy and also installation costs Continue Reading
