Photons, Electrons, and Dirt

The Nixie tube connected to the socket / driver board and the socket / driver board connected to the upside down power / controller board.

The first in this series of posts described building a socket and driver board for a Dalibor Farny R|Z568M Nixie tube and driving the tube using a power supply and Particle Photon from another Nixie project. This post covers building a power supply and controller board that mounts underneath the socket and driver board to power the Nixie tube and control the displayed digits.

I recently ordered one of Dalibor Farny’s R|Z568M Nixie tubes. I wanted to get the tube powered up and displaying digits so I designed a small circuit board to act as a socket and switch the anode and digit cathodes on and off. This board will connect later to another board containing a 170 volt power supply and a microcontroller via some headers. Read on to find out more about the design of the socket and switch board.

The business end of a horizontal drilling machine’s drill head.

In part one of this series of posts, we covered the broadband launch, the start of construction in my neighborhood, the vaults and flowerpots, utility locates and dig ins, and conduit. In part two, we’re going to look at putting the conduit in the ground using horizontal directional drilling and then we’ll continue to document everything as construction moves forward. Read on to hear more about the process as the build in my neighborhood continues.

Splice vault. Bicycle not included. Notice the fancy Fort Collins Connexion and City of Fort Collins logos?

This post if the first in a series of post that describe the installation of the Fort Collins Connexion municipal broadband service. I’ll append new information to the bottom of the post whenever something happens on my street. When the post gets too long, I’ll start a new post. Work has been going on in the northwest corner of my neighborhood since the end of July. It’s only in the last week that activity has started happening on my street. Read on to hear more about the process.

Control the bicycle traffic signal over Wi-Fi using a Particle Photon.

In the first post in this series, we built a miniature LED bicycle traffic signal using 3D printing, laser cutting, a sticker, and an Adafruit Neopixel Jewel. In this post, we’ll look at bringing the signal to life using a Particle Photon. We’ll start with basic code to blink the traffic signal green, yellow, and red then add code to control the color over the web using the Particle Cloud or locally using an iPad and the Art-Net protocol.

Completed bicycle traffic signal cycling through traditional traffic light colors. This is the older, narrower version of the hood.

This is the first in a series of posts describing how to build a Wi-Fi enabled bicycle traffic signal. In this first part, we’ll go over the required parts, using a 3D printing and laser cutting service to build the needed mechanical components, and assembling the traffic signal. In the second and third posts, we’ll connect the bicycle traffic signal to a Particle Photon and Adafruit Feather M0 Wi-Fi respectively to enable the traffic signal to be controlled via Wi-Fi. In the final post, we’ll build our own control electronics, add a small base to house the new electronics, and expand the signal to three lights.
