Analog front-end IC linearizes sensors

A 10-channel temperature-measurement IC, the LTC2986 from Linear Technology directly digitizes any combination of thermocouples, RTDs, thermistors, and external diodes with 0.1°C accuracy and 0.001°C resolution. The analog front-end device combines three 24-bit delta-sigma ADCs with all the necessary excitation and control circuits for each sensor. On-chip EEPROM stores user configuration data and custom sensor […]

MPPT Solar Charger Design

Electronics News Updates / Ibrar Ayyub

I’m currently waiting for the boards for my Ultrasonic Anemometer Rev B to arrive from Hong Kong and this gives me some time to write about the MPPT Solar Charger design that I did quite some time ago. I published a series of posts on a Arduino MPPT Solar Charger Shield and got a lot of encouraging feedback.

Infinite Noise True Random Number Generator

Electronics News Updates / Ibrar Ayyub

For instructions for compiling the and using Infinite Noise TRNG driver, go to the software sub-directory, and read the README file there. Both Linux and Windows are supported. The Infinite Noise TRNG is a USB key hardware true random number generator. It uses what I call a “Modular Entropy Multiplier” architecture (previously Infinite Noise Multiplier

Tiny Lisp Computer

Electronics News Updates / Ibrar Ayyub

This article describes a self-contained computer with its own display and keyboard, based on an ATmega328, that you can program in Lisp. You can use it to run programs that interface to components such as LEDs and push-buttons via the I/O pins, read the analogue inputs, and operate external devices via the I2C and SPI

Hacking a tablet to force an Android update

Electronics News Updates / Ibrar Ayyub

As regular readers may already remember, my second-generation (2013 “FHD”) Nexus 7 tablet has been a repeated topic in past blog posts. And in most-to-all of them, I grumble about the fact that it’s still stuck on Android v4.4.2 (which dates from early December 2013), presumably due to Verizon constraints (it’s a cellular-plus-Wi-Fi model), and

Cheap Serial Terminal

Electronics News Updates / Ibrar Ayyub

How about a cheap serial terminal for less than a fiver all-in? In a previous blog entry I’ve been working on more developments for the increasingly powerful home control system using an Arduino as a kind of universal I2c peripheral to the ESP8266. The reason for that is just the vast range of driver software
