External Hardware Monitor

Hi guys! Today I will show you how create an external hardware monitor with any Arduino board(in my case a pro micro board), a Nokia 5110 LCD and some VB programming! Let's get started! ps. Sorry for my bad english Step 1: What Is the Aim? The aim of this project is for monitoring pc hardware while you're in game. There are other many system to do that, like afterburner ingame overlay, but for me is too cum ...

MAX232: The classic IC lives on since 1988

The June 23, 1988 issue of EDN included a Maxim Design News insert where we asked "Who in their right mind would choose a computer interface standard that uses ±12V supplies, requires expensive connectors, works over a limited distance, is error prone, difficult to network, and has no current loop isolation?" Yet, here we are 28 years later and the classic interface lives on, particularly in industrial appl ...

Optogenetic hardware setup

Arthur English's group at Emory has developed a custom device that they have used for stimulating peripheral nerves optically in anesthetized mice using a standard optical fiber. The device is compact, rechargeable battery-operated, and controlled either manually or by computer using an analog input. Essentially, laser LED illumination is coupled to an optical fiber by a collimator and can be attached to a ...

Magnetic Field Measurement Using HMC5883 and Arduino Nano

The HMC5883is a digital compass designed for low-field magnetic sensing.This device has a wide magnetic field range of +/-8 Oe, and an output rate of 160 Hz. The HMC5883 sensor includes automatic degaussing strap drivers, offset cancellation, and a 12-bit ADC that enables 1° to 2° compass heading accuracy. All I²C Mini Modules are designed to operate at 5VDC. In this tutorial we are going to explain the det ...

Inside the tiny RFID chip that runs San Francisco’s race

How does a tiny chip time the runners in the Bay to Breakers race? In this article, I take die photos of the RFID chip used to track athletes during the race. Bay to Breakers is the iconic San Francisco race, with tens of thousands of runners (many in costume and some in nothing) running 12km across the city. To determine their race time, each runner wears an identification bib. As you can see below, the ba ...

ESP8266: SSD1306 Oled Library Release

The “ESP8266 OLED SSD1306″ is an open source library which allows you to control those pretty OLED modules from our beloved ESP8266 module. Fabrice Weinberg cleaned up all the ugly pieces of code which I initially wrote caused by my near C/C++ illiteracy. He also added support for Pasko’s BRZO I2C library which is partially written in assembler and allows a much higher throughput over the I2C channel. Fabri ...

Prototype to production: Arduino for the professional

Despite its popularity among hobbyists and electronics enthusiasts, the Arduino has become infamous among professional embedded systems developers. I must admit that for the longest time I also viewed the Arduino as so simple it was nearly useless for professional developers. But I have changed my mind. I’ve found that on a number of occasions over the last few years, rapid prototyping using Arduinos and Ar ...
