Custom-Built Isothermal Heat Conduction Calorimeter

Prologue A Heat Conduction Isothermal Calorimeter is used to determine the heat flow rate of a specific process or reaction, in my case, it is designed to measure the heat rate of hydration of cement in the field of Civil Engineering and Materials Science. The purpose of this custom-built Isothermal Calorimeter is to undertake the ASTM C1702 Standard Test Method for Measurement of Heat of Hydration of Hydraulic Cementitious Materials Using Isothermal Conduction Calorimetry....

Teensy LC Setup on Linux

Introduction Teensy LC (Low Cost) is a 32-bit microcontroller board that you can get from PJRC a company in Oregon, USA, which is owned and managed by Paul Stoffregen. It features an ARM Cortex-M0+ processor designed for low-power, low-cost devices. You can buy it and read more technical details on PJRC’s Teensy LC page. I am writing this tutorial as a complete guide for starting with the Teensy LC development and also as a reference for myself in case I need to revisit it in the future....

Teensy LC Challenge

Quest 001: Teensy LC Challenge Prologue It all started with a simple tweet. I was going through my parts inventory and found the two items collecting dust — I won them as prizes on HackADay.io for two of my projects there (you can check my profile here). So I won 2 prizes from @hackadayio back in 2015: a "#Teensy LC" & a "Cordwood Puzzle". Thanks @szczys @asiwatch I was busy since then & never used it, so now it's time to put it to Good Use....
