Ken Boak has designed a tiny 16-bit computer around a FRAM based MSP430 microcontroller. He writes: In this post we look at a new MSP430 FRAM based device – the MSP430FR2433. It has 15K of FRAM, 0.5K of Info FRAM and 4K bytes of SRAM. As well as the memory, there are 3 serial communications […]
Internet-Connected Migrane or Allergies Detector
https://www.electronics-lab.com/internet-connected-migrane-or-allergies-detector/
adafruit has published an IoT Migrane or Allergies Detector. This project uses Feather HUZZAH ESP8266 wireless microcontroller board to pull a forecast from the accuweather.com web site, then distills this to its barest essence: good news or bad news? An ambient information display is an indicator which conveys meaningful data non-verbally. Unlike a computer screen which […]
ESP12e + OLED display – a try to make a smartwatch

Its JavaScript interpreter gives you instant feedback so that you can experiment and develop whatever your level of experience. Even if you can’t […]
Testing DRAM Using an Arduino
https://www.electronics-lab.com/testing-dram-using-an-arduino/
Chris @ insentricity.com wanted to test a few dozen individual RAM chips so he decided to use Arduino to make his life a little bit easier. In the article he explains the interface with Arduino and gives the code on github. My first thought was to test the chips in the TL866CS, but it doesn’t support […]
