I have been using Opencode to work on a couple of ESP32 projects that are of a more “Maker” nature. At some point I realised that I also needed a case and decided to set Opencode loose on it too.

The workflow for this is simple, but awful:

• describe the case in words
• Opencode (using Big Pickle because FREE) creates an OpenSCAD model
• Render the OpenSCAD model
• Wonder what the hell Opencode was thinking
• GOTO 10 and the cycle continues ad nauseam

What you need is some way for Opencode to verify what it has done and iterate.

As part of my continuing experiments with AI, I regularly use models from Hugging Face. Ollama makes it really easy to run models locally from their own repo, but sometimes they do not have exactly the model one wants.

Why Use Hugging Face

While Ollama has its own curated repository of models you can use, Hugging Face has kind of become the community default. The choice is much larger and opens up possibilities that are not available if you just stick with Ollama’s own repository. For mainstream models, there maybe quantization that are not available in Ollama’s own repo. There are plenty of fine-tunes of more mainstream models that are only on Hugging Face.

Once again I have a new tool I have been playing with, once again AI related. One of the tools I have been using is n8n which is a workflow automation platform. It enables us to integrate multiple applications and services through a visual interface. While it is very much an enterprise solution, it is FLOSS and we can deploy it at home, albeit with some caveats and/or workarounds.

One of the really powerful parts of N8n is that we can integrate with various AI platforms, including all the usual suspects: Claude, ChatGPT, etc. Of course I want to keep things local, which N8n caters for with Ollama.
