This work is still-in-progress; originally started on 25 March, 2020. And, interestingly gained some interest during that time on-wards. This work is NOT affiliated with any group, organisation or team. The HackADay project page. Prologue Near-infrared spectroscopy (NIRS) is nothing new. However, it’s a relatively new method deployed in the field of virology. It has been successfully used before to identify HIV-1 and Influenza virus.
This project is part of the Teensy LC Challenge Teensy Project 002: HID USB Keyboard Checkout the source code on Github. Teensy Setup The environment setup section is common to all the Teensy LC projects, so I created a single post with the required instructions to set up the Arduino IDE, Teensy Loader application, Teensyduino and Linux udev rules. If you have not setup your Teensy LC yet, please go to the complete setup guide
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.
This project is part of the Teensy LC Challenge Teensy Project 001: Blinking LED Checkout the source code on Github. Teensy Setup The environment setup section is common to all the Teensy LC projects, so I created a single post with the required instructions to set up the Arduino IDE, Teensy Loader application, Teensyduino and Linux udev rules. Go to the complete setup guide First Usage: Blinky Program This section is also repeated in the setup guide since it’s basically the first project introduced in this quest.
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.
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.
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).
