An RGB LED has 4 pins, one for each color (Red, Green, Blue) and a common cathode. It has tree different color-emitting diodes that can be combined to create all sorts of color! Any color is possible depending on how bright each diode is. In this tutorial you will learn how to use an RGB […]

We live in an exciting time where we see a resurgence in electronics as a hobby. Mass production has wiped out a generation or two of kids learning to build radios from scratch with their mom or dad. In the good old days, not sure when, you had companies like Heathkit walk you through building

Since there is already a write-up on why and how I made the business card project, this post will only detail the changes made since the first version. If you would like more information on how this project was made and how it works, please visit the original write-up. The initial USB business card was

Light destroys art. Some wavelengths are more damaging, some media are more vulnerable to damage, but all curators and conservators face a fundamental conflict between the demands of preservation and the desire to display the objects in their care. These conflicts come to the forefront whenever a museum must decide which objects to display, for

Spansion has announced its ARM Cortex-M series microcontroller offering following the acquisition of Fujitsu’s microcontroller business. In August, the flash memory chip firm paid $110m for Fujitsu’s microcontroller and analogue business. Spansion also acquired $38m of MCU inventory. Designated the FM family, it will deliver 200MHz/250MIPS performance for applications such as factory automation, building management and motor control. There are different voltage ranges from

Many of today’s most challenging computer science problems involve very large data structures, unstructured data, random access, or real-time data analysis. These computationally intensive problems are not well aligned with traditional CPU and memory system architectures; they require a fundamentally new approach to computing. Micron’s Automata Processor is a massively parallel computer architecture that provides

The Wino board is an Arduino-like stackable development system which is both smaller and cheaper than Arduino units and features built-in WiFi as standard. The main Wino controller board measures 26.5 x 18.5 mm and fitted with an Atmel ATSAMD21 running at 48 MHz with 128 kB Flash storage and 16 kB RAM. The board

Today I will show a very simple ionization chamber that can detect radioactivity. I was able to detect with it ionizing radiation from a smoke detector (Am241 isotope). It’s also immune to electromagnetic interference (EMI) due to a good shielding. This device doesn’t explicitly use any power supply. It’s connected to a multimeter set to

Low losses, precise design, low power consumption and moreover a very affordable price are one of several reasons saying for the signal relays from Fujitsu. Despite a big advance in a segment of semiconductors, there are still many reasons for usage of electromechanical relays. Galvanic isolation of a driving signal from a switched signal, resistance
