Field log · Selected entries 2025–2026

What we worked on, the notes we kept, the surprises we found.

A field log is what an electrician would call a job book. We sanitize each entry — names off, addresses generalized — and publish it because if you're going to hire us, you should be able to see the work.

The clipboard in the cab of the service van. We migrated the job log to a tablet in 2021; the clipboard still rides along because there's nothing faster for a sketch on the way home.

Entries are sorted newest-first. Each is a finished job — the load calculations, the parts, the route, the surprises. Customer names appear only with explicit signoff; the towns and counties are real.
