Getting Started With a 128x64 Pixel SSD1306 OLED Display - Blog

July 12, 2021

If you have browsed online auction sites and/or various small electronics projects to any extent, there’s a good chance you have come across a .96” 128x64 pixel OLED display, based on the SSD1306 driver.


Preventative Maintenance for Automation: Break Machinery to Make it Better - Story

June 24, 2021

I now primarily work as a sort of tech journalist–documenting interesting projects and technology, while building a variety of projects that I can write about and sometimes sell. Before that, I spent well over a decade as an engineer working in manufacturing automation. In this arena, as in life, the universe, and everything, there comes a point where a “thing” works more or less as it did yesterday, but in a state that could be improved.


Roku Remote Rechargeable Upgrade - Blog

June 14, 2021

For somewhere around a decade, I have relied on streaming for the majority of my television watching. This meant a computer in the early days, along with a surround sound home theater setup. At some point, however, we simplified to a single Roku Player and the TVs built-in sound.

Simplify Code With Arduino Functions - Blog

June 10, 2021

Arduino boards, and the Arduino IDE is wonderful for creating small snippets of code that can activate an LED, read a sensor, activate a servo, or any number of unique physical computing applications. Such actions generally start out simple–e.g. blinking an LED on a timer–but can eventually become quite complicated as programs expand and the programmer’s skills increase.

Ethernet Cable Alternative Uses - Blog

June 02, 2021

Today, wireless networking technologies like WiFi and Bluetooth have taken over a huge amount of the world’s short distance data transmission duties.


Creating The Perfect Workbench - Blog

May 21, 2021

The “perfect workbench” is of course a matter of opinion and personal needs. At this point, however, I’ve used and built several, so I’ll say that at least qualifies me to throw my opinion out there. While striving toward the optimal workbench has been (and still is) an evolution, not a careful plan, here’s a few things to look for in your bench:

It’s no exaggeration to say that 2020 was a challenging year.


Set Up Headless Raspberry Pi Using MacOS - Blog

May 07, 2021

While the Raspberry Pi works extremely well in a “headless” mode without a monitor, setting this up can be a little tricky. In this article we’ll go over how to do so specifically under macOS, allowing you to get your RPi remote computing node up and running without using an external monitor whatsoever.

Alternative Internet Access Methods - Blog

April 30, 2021

Today you likely take access to the Internet for granted, using your phone for short bits of communication, or a computer connected via a router and WiFi or a directly wired connection for more serious input.

Starting into the World of Small-Run PCBAs - Blog

April 12, 2021

A little over a year ago I ordered my first printed circuit board (PCB) from OSHPark, which contained an ATtiny85, along with resistors and a few blinking LEDs. Since then I’ve designed several more boards, and fairly recently I made the switch to surface mount components.

How to Connect to a Raspberry Pi Via SSH Using the Macintosh Terminal - Blog

March 31, 2021

As outlined in this November 2020 article, I recently switched from a PC to a Macintosh. Overall, I’m quite happy with the move, in a large part because it feels like they do all the “little” things right.


Raspberry Pi OS Fan Control - Blog

March 15, 2021

As you probably know, Raspberry Pi single-board computers, especially Pi 4 models, can get quite hot. While passive cooling options are often good enough to avoid overheating and thermal throttling, at some point you’ll need to think about using a cooling fan. The Raspberry Pi’s GPIO pins don’t supply enough current to power even a small fan, but there are several ways to power and control a fan with the Pi.

Exploring Tech In the 90s with BBSes - Blog

March 04, 2021

Some time in the early 1990s, my parents got “their” first computer, a 386 SX by a company called “USA Flex.” This device had 640KB of memory, and a “turbo” button to go from 8 MHz to 16 MHz–a relief if that kind of blazing top speed was too intimidating–and came with Windows 3.

Designing an Automatic Bicycle Wheel Light PCB - Blog

February 24, 2021

While it’s still a bit cold to ride a bicycle right now over much of the United States (and the Northern Hemisphere in general), here in Florida, it’s a great time to get outdoors. The only small problem is that as the sun sets fairly early until daylight savings time starts. It’s therefore quite possible then that you might end up being out beyond sunset, and in that case it’s a good idea to have a light to keep yourself visible to others.

Reserve Static IP Addresses on Your Router - Blog

February 09, 2021

In a previous article, I outlined how to connect to your Raspberry Pi via SSH, and noted how you can assign a Static IP address to allow you to consistently find it.

Nearly Triple Internet Speed with Wired Ethernet and Simple Upgrades - Blog

January 14, 2021

As a result of the current pandemic, more people than ever have been working from home. While there are definite drawbacks. As someone who has worked from home for years, I’d argue the positives far outweigh the negatives. Regardless of what happens in the future, I suspect that working from home will be, if not the "new normal," at least much more common.


Raspberry Pi Home Automation Part 4: Automation and Customized User Interface - Blog
