Notes from the workbench.
I’m MrAgui. This blog is where I write up hobby projects: small home Bitcoin miners, all sorts of DIY, coding with the help of AI, Local LLMs, you name it.
Nothing here is related to my day job. It’s just stuff I enjoy and want to share in case it saves someone else a few evenings.
