Anyone else have a pile of relays in the parts bin with 24V coils? I do, so I've designed an isolated controller board that includes the power supply, current loop drive circuit, and a DIP16 footprint relay. Now I can make use of my large stock of relays without building a point-to-point power supply and controller every time.
I was recently tasked with building a new pfSense box for the office. We needed three or four Ethernet ports, and wanted to use a 1U Intel Atom based server. Finding a quad port card was a little challenging, so here's a writeup on picking the right card for your build.
The Kickstarter-funded Sabernetics Technology OLED Display arrived yesterday. Before committing it to a project, I wanted to ensure the display was functional and get a feel for its daylight readability. The Bus Pirate was the obvious choice for prototyping.
I finally finished rewriting the site using Jekyll, a blog-aware static site generator written in Ruby. Although the process required reformatting all existing site content, the move appears to have been well worth it! Expect a higher frequency of updates now that writing an article only involves creating a textfile and executing a script.
