  • Linear Voltage Regulators



    In this article we explore some high level concept of a series topology linear voltage regulator with some SPICE simulations and mathematical analysis.
  • Decibels - Fundamentals and the Time Domain



    In this article we explore the fundamentals of the Decibel units and how to derive them using only power and resistance. We then provide an example of how these calculations appear in the time domain such as on an oscilloscope.
  • Clamp Connect: Free your Fluke devices!



    The Fluke 376FC is a Bluetooth wireless AC/DC clamp meter which communicates over the BLE protocol using a proprietary mobile application interface. As of writing this article there is no known desktop application or API for interfacing to this unit. Therefore the goal is to produce a working interface which connects to the unit and allows a user to interface to the device remotely from a PC.
  • Coto Relay Multiplexer



    In this article we discuss the design of a Form-A reed relay based multiplexer for test and measurement applications.
  • Digital Isolators



    In this article we discuss the design and development of a high reliability, high density digital signal isolator with parasitic powered inputs.
  • RTD Simulation



    In this article we discuss the development of a static resistance simulator for use in functional testing.
  • Resistor Tolerances and Statistical Distribution Thereof



    In this article we discuss the statistical distribution of 1% metal film and 5% carbon film resistors.
  • Modeling a Wound Toroid in Solidworks



    In this article we discuss the modeling of a wound toroid using Solidworks. This method uses surfaces and is a very fast method of creating a helical path around a curve. This method could also be used for generating complex wrapped helix shapes around objects, too.
  • Atmel SAMD51 20x4 LCD Driver



    In this article we share the source code and details on a 20x4 LCD driver with a hardware abstraction layer to allow for ease of migration to other microcontroller platforms.
  • Automated Continuity Test System



    In this article we discuss using the Qt5 framework to create a test automation application to assist with testing of devices where hands free recording may be useful.
  • Mathematical Reference

    In this article we discuss some useful mathematical formulas in a quick reference format and some helpful heuristics to solve problems.
  • Better Breakout Boards



    How to make better breakout boards by standardizing your designs.
  • Reactor Control System



    The reactor control system (RCS) is a fully automated control system targeted at the micro-reactors market for development and research of catalytic materials. It provides a low-cost entry for automation of pilot scale and laboratory research and development systems while offering extensive data logging capability and critical safety features including sequenced shutdown protocols as well as configurable warning, fault, and critical limits.
  • USB Thermocouple under 16KB on an Atmel SAMD11



    In this article we discuss the basics of thermocouples, software USB stack setup using the Atmel API without using an external oscillator, and tips for shrinking MCU code on a constrained system.
  • Measuring Lorentz Force



    In this article we discuss measuring the force created by a current carrying conductor in a magnetic field.
