The WiFi SSR board project changed a bit and I use classical relays instead of SSRs now. The reason is that SSRs tend to get quite hot when switching larger loads, and the 8A relays I last used actually could be used for max 2.5A load switching with no heat sink. The high quality relays I […]
NUREMBERG, Germany–(BUSINESS WIRE)–Silicon Labs (NASDAQ: SLAB), a leading provider of wireless connectivity solutions for the Internet of Things (IoT), today unveiled a complete Bluetooth® Smart solutions portfolio designed to help developers minimize the energy consumption, cost and complexity of wireless IoT designs. Silicon Labs’ recent acquisition of Bluegiga, a leading supplier of wireless modules and
AC/DC modules Traco TMPS 03 with dimensions of 1“x1“x0,6“ represent a top-class solution of power supply with minimum space requirement. Power supplies with a high power density (W/cm3) are nowadays offered by several producers. However, perhaps the biggest challenge is a miniature power supply with a power of say a few Watts. It´s because even
Frequency counter using Arduino (upto 40KHz). Many guys here were asking for a frequency counter and at last I got enough time to make one. This frequency counter using arduino is based on the UNO version and can count up to 40KHz. A 16×2 LCD display is used for displaying the frequency count. The circuit
Hi all, First of all , i’m dutch and from Belgium. I’m new with and for David-laser. I tried to find a clear site and list for controlling. I’ve found this schematic through ‘google’ I was wondering, can i use Adafruit Motor/Stepper/Servo Shield for Arduino kit – v1.0 instead those easydriver v3 according the image:
Today we release the latest addition to the Arduino family: the Arduino Due. This board is based on a powerful 32bit CortexM3 ARM microcontroller made programmable through the familiar Arduino API and its development environment. It’s an important step forward for Arduino as it increases the computing power available to Arduino users keeping the language
PORTLAND, Ore. — A new type of transistor harnesses a new effect–called the quantum spin Hall effect — to create a topological field effect transistor (TFET) according to a Massachusetts Institute of Technology (MIT) researcher who recently moved to the newly formed Department of Materials Science and Engineering at Texas A&M University where the Texas
