Fourth level heading

Paragraphs and inline formatting

This is a regular paragraph. It contains bold text, italic text, bold italic text, and inline code. Here is a link to something in the middle of a sentence.

This is a second paragraph to show spacing between paragraphs. It has ~~strikethrough text~~ and also a longer passage to show how body text wraps across multiple lines when the viewport is narrow enough to force it.

Thoughts on industrial HMI design

Wed, 20 May 2026 00:00:00 +1000

I’ve been staring at HMI panels for years now and I have opinions. Most industrial touchscreen interfaces are bad in ways that are completely avoidable. Not bad because the hardware is limited — bad because nobody designing them has thought about the person standing in front of them at 2am during a fault condition.

The problem with most panels

The default approach seems to be: cram every possible reading onto one screen, use bright colours for everything, and make all the buttons the same size. The result is something that looks busy when things are fine and indistinguishable from normal when things are broken.

CNC controller retrofit

Fri, 15 May 2026 00:00:00 +1000

Replaced the original Fanuc 0-M controller on a 1994 Takisawa lathe with a LinuxCNC setup running on a Mesa 7i76e. The old controller had been intermittently faulting on the Z-axis encoder for months and replacement boards are either unavailable or priced like they contain precious metals.

Background

The lathe itself is mechanically sound — ballscrews are tight, ways are in good shape, spindle bearings were replaced four years ago. The only weak point was the control electronics. Rather than hunting for NOS Fanuc boards or paying for a Fanuc-compatible retrofit kit (which is mostly what you’re paying for: Fanuc compatibility you don’t need), I went with LinuxCNC.

The matcha monday webring links could go here. I made a shortcode for them. Thats unavoidable JS though im afraid.

Contact

These might be better folded in to another page or even placed on the bottom of the site layout. Making them a distinct page for now.

The site is currently zero javascript for religious reasons but you could add a nice contact form with only a tiny bit of JS. Or even with no JS if you don’t mind leaving the page on submit.

Links

Mon, 01 Jan 0001 00:00:00 +0000

I actually like link pages the most when I check out a personal site, seeing what people like to read or watch feels like it tells me more about them than their about page does.

Now

Mon, 01 Jan 0001 00:00:00 +0000

A now page is supposed to be a quick look to get an idea of what you’re up to right now. Work, reading, learning, side projects, current location etc.

I like now pages but up to you.

See nownownow.com for the convention.
