About

This is a working notebook, not a company and not a service. I write things down after they cost me time, so the next person — usually me — spends less of it.

What's here

Notes on control loops, instrumentation, pumps and PLC work. Each one comes from something that actually happened on a plant, with the identifying details removed. Numbers are from real measurements unless the note says otherwise.

What's not here

No consulting offers, no products, no newsletter, no tracking scripts, no comment section. Nothing on this site collects information about visitors beyond the ordinary web-server log that any site keeps.

Corrections

If something here is wrong, I would rather know. Write to hello@ag88-engineering.com. Corrections get folded into the note with a line at the bottom saying what changed and when.

Reuse

Quote what's useful, with a link back. The notes are written to be used, not guarded.
