Hot rods keep the die cool

20160223104825_hotrod-qfn

Clemens Valens @ elektormagazine.com shows us a new IC Package that keeps the IC cool.

Texas Instruments’ HotRod QFN is a thermally enhanced plastic package with solder lands on all sides as well as power buses for enhanced current carrying capability. Inside the package the die is mounted on a copper lead frame which eliminates the power wire bonds, improving electrical and thermal performance. This technique also improves application efficiency and minimizes package parasitic radiation.

0.8A step-up DC/DC converters in a tiny package

main


Torex Semiconductor’s XC9141/XC9142 series of 0.8A step-up DC/DC converters come with an input–output disconnection function (load disconnection function) to prevent malfunctioning during standby, and for device functionality that enables power supply to RTC.

When the output voltage is 3.3V, the IC can start from an input voltage of 0.9V with a resistance load of 100Ω, enabling use in devices driven by one alkaline or nickel-hydrogen battery. The input voltage range is 0.65V to 6.0V, and the output voltage range can be set from 1.8V to 5.5V (accuracy ±2.0%) in steps of 0.1V. A switching frequency of 1.2MHz or 3.0MHz can be selected to match the application.

LTC7813 – IC cascades boost/buck controllers

7813

Linear Technology Corporation introduces the LTC7813, a dual output (boost + buck), low quiescent current synchronous DC/DC controller. When cascaded, its independent step-up (boost) and step-down (buck) controllers regulate the output voltage from an input voltage that can be above, below, or equal to the output voltage, including during an automotive load dump or cold crank. Unlike conventional single inductor buck-boost regulators, the LTC7813’s cascaded boost + buck solution provides fast transient response with continuous, non-pulsating input and output currents. It substantially reduces ripple voltage and EMI, ideal for automotive, industrial and high power battery operated systems.

Door Status Monitor using the ESP8266

door_sensor

Rui Santos tipped us with this tutorial on how to monitor the status of your door using an ESP8266.

In this project you’re going to monitor the status of a door using an ESP8266. The goal of this project is to show the endless possibilities that this $4 WiFi module offers when integrates with a free platform that I’m about to show you.

Display YouTube Stats on LCD Screen

FXNMAU3IMNUVGVM.MEDIUM

In this guide “padeath” shows us how to use a 320×240 LCD display with Arduino UNO to display youtube statistics. The stats are updated once in a minute using the google API.

This little Instructable will show you how to use a 320×240 pixel LCD screen connected to an Arduino Uno with a network shield too, to show stats for Youtube channels.

I created this as I wanted to see how many subscribers and views I had on my channels without having to check Youtube 🙂 The stats update on the LCD screen every minute using the google api.

MNT VA2000, an Amiga 2000 Graphics Card

proto2-populated2

This is an Amiga 2000 Graphics Card (Zorro II), written in Verilog by user “mntmn” @ github.com:

This repository contains my Kicad schematics and Xilinx ISE/Verilog files for my graphics card project. This is a work in progress, started in October 2015. The first 4 prototypes were assembled in Jan/Feb 2016 and had noise problems, so I started a redesign on Feb 13, 2016.

WeMOS D1 ESP8266 Over the Air (OTA) update

In this video educ8s.tv is going to show us how to wirelessly update the code of our Arduino project, using the WeMOS D1 ESP8266 based board. This is an impressive, and very useful feature.

A few weeks ago, we took a first look at the very promising new board, the WeMos D1. You can watch that video by clicking in the card here. The Wemos D1 is an ESP8266 based board which resembles the Arduino Uno board but it offers a lot more. Huge processing power, large memory and WiFi at a very low cost, less the 8$! You can find a link for the board in the description of the video.
