Convert Text to Audio on Linux – Coqui TTS
In a separate post on my blog, I documented a simple way to convert text to audio using Google’s Text-To-Speech service. This works for small projects. But, during a recent conversion, I ran into an error where my requests were getting blocked by Google for using the service too much. I didn’t realize they capped…

I’ve needed a place to put sunglasses in my car for years. My sunglasses have typically ended up in one of the cup holders. Recently, it dawned on me that I could print a clip or holder that would attach to my sun visor to hold my sunglasses. I looked at the various 3D design…

FreeCAD Import STL
I’m not a FreeCAD expert. I bought a 3D printer and am constantly coming up with new ideas for 3D prints to solve issues around my house and office. That required me to begin learning how to use CAD software and, as an open-source advocate, FreeCAD was the obvious choice for CAD. I design most…

Bambu A1 Mini – 0.2 extruder doesn’t work!

Airtable Forms for Third-Party to Submit Updated Information
I have a use case that is probably more common than I realize. I am a faculty member at a university and our department wants to keep track of our alumni. To do that, we built an Airtable base that contains basic contact information for them. We can obviously update the base by hand, but…

Getting Ollama and Open WebUI Working on Kubuntu 23.10
I have two specific use cases for setting up AI locally instead of using ChatGPT (for which I have a subscription as I use it for a variety of tasks, as does my wife). I needed to analyze interviews but couldn’t upload them to the web for security reasons. I also wanted to work on…
