I haven't exactly made it a secret that I use Pelican to write this blog. Sometimes I'm active, and sometimes I'm not. As pelican is a static site generator based on templates and text files, I have been doing the build and deployment by hand. When I have been away …

I had an instance at work where I needed to quickly calculate an estimate for Reynolds Number for 0 gallons/min to 10 gallons/min for several different pipe diameters.

$$Re = \frac{QD}{vA}$$
• $$Re$$ = Reynolds Number (dimensionless)
• $$Q$$ = volumetric flow rate ($$m^3/s$$)
• $$v$$ = kinematic viscocity of the …

# Introduction

Throughout the last few years, KiCAD has been my goto tool as a hobbyist and as a professional. I readily admit that KiCAD lacks some of the polish and features found within Altium, Allegro, and PADS. Despite the lack of features, KiCAD has one advantage that those packages did …

# Purpose

This document is intended to provide a guide regarding the use of Dispatch.

Source code may be found on github.

# Concepts

## Structure

# Introduction

I recently had a work move and wanted to make something of an impression. My ambition to be, both, productive and cool has led me to the relatively simple project of placing a coffee cam in the workplace.

Ideally, I could attach a pi with a camera to the …

# Purpose

This document is intended to document the curve tracer This document will be updated through revisions and can be used as a persistent reference, regardless of the 'date posted'. As more information becomes available, documentation will be added.

The original post for the curve tracer can be found here …

# Engineering Notation

Anyone reading this will likely already have a background that covers engineering notation, so I won't go into it deeply. Computer scientists might also call engineering notation a 'human-readable' numbers. Instead of 4096B you might see 4kB or 4.096kB, depending on your precision.

There are more expansive …

## What is It

Python Jumpstart by Building 10 Apps is a course designed as an introduction to Python. This course is not your typical introduction found on Coursera or EDX, which are usually designed around some weeks-long introduction that get you to objects around week 8. This course - which you …

I was browsing Sparkfun a few days ago and came across their OpenScale board. The board is basically a load-cell amplifier with a microcontroller interface which will output data - via an FTDI chip - to the PC or other UART at a fixed interval. The microcontroller also has …

## Hardware

Hardware was received and built up quickly in the past couple of days. In fact, all has progressed more quickly that I initially imagined. Osh Park - those loveable guys - bumped my order up to the 'premium' panel, so I received the boards a week earlier than anticipated!

### Rework

That …
