Running multiple computers can have advantages. In my case at my desk I run a windows machine during the day, and keep a Linux machine running around the clock for various tasks. Usually remote terminal access is all that is needed for day to day interfacing, but sometimes I’d like to be able to access

With the advent of larger and larger phones and mobile devices that contained increasingly larger batteries to accommodate their thirst for energy, new types of power sources were created that centered around the 5v USB standard, but also allowed for increased voltage and current, in order to accelerate the time required for them to charge.

While the Atmega328 has enough processing power for many applications, sometimes you need a bit more. While trying to drive OLED displays, and run various other time sensitive tasks, you can come into performance issues. A faster chip, that is also supported quite well by the open source community is the STM32 family. There is

This article is on the final revision of the Arduino Fan control board “CoolRunnings”. I’ve written about the first two revisions, from the board that I etched myself, to the first one from a board house, which still contained a boost converter. After that one, I designed one to be powered with a barrel jack,

The ESP8266 relay project started off as an attempt to control a relay with the ESP8266 from a wireless interface, such as a web browser. The idea can easily be achieved with a few different modules which are available from eBay relatively inexpensively. I however usually don’t like the idea of assembling several modules to

After my first fan controller was competed and working, I was pretty happy with it. But as I learned more, experimented more, and became familiar with more hardware, I realized much more could be done with the controller. With the previous controller, I used the Attiny85, which was perfect for the job it was given,

A few years ago, I was spending a considerable amount of time away from my apartment. Some of this time arose during the winter months, and I found myself wanting to reduce the heating costs of the apartment, and therefor the temperature while I was away. Because the unit is adjacent to a few others,

I have a computer desk that I like quite well. It it was designed to be used with a desktop computer, and has all the attributes that are common with computer desks, such as keyboard trays and so on. One thing that may be a bit less common however, is that there is a cabinet

In early 2017, I developed some interest in seven segment displays, and in how to drive them. Because of the large wealth of information surrounding the Arduino IDE on the internet, finding a program that could drive such a display proved to be a relatively easy task. Before long, on my breadboard I had a

Recently, I’ve been using some DS18b20 One-Wire temperature sensors for a few projects, including a serial to USB temperature monitoring device I built for remote monitoring. After testing the sensor and logging profiles for a few weeks in a stable environment, I decided it would be interesting to move the sensor to an outdoor location.
