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.
Prologue It was a great Friday, the 31st of August 2007 at 22:25:25 I etched my first PCB ever at home, it was the second year of high school and I was so excited about it. After doing some research and information gathering from some friends who happen to be great engineers. This is how I got started with electronics — believe it or not, by building my first PCB using Ferric Chloride FeCl3 solution with 60% concentration and a blank copper Printed Circuit Board (PCB).
