83.2 hours behind this site
Time on my public builds and on this website, counted by a tracker on my Mac, plus the hours I logged by hand. Tracking began on 30 Sept 2026, and anything before that isn't here unless it's shown as logged.
72.7 h tracked, 10.5 h logged by hand. Complete to 14 Nov 2026. Dates only, no times of day.

Where the hours went
Whole record. Pick a project or a kind of work to see only that; pick it again to clear.
Projects
Hours, then commits
- 44.3 h
- 3.1 h
- 26.9 h
- 23.5 h
- 0.1 h
Two projects at once, counted once: the rows add up to 14.5 h more than the 83.2 h total.
Kinds of work
Solid tracked, hatched logged by hand
- 25.7 + 2.0 h
- 33.6 + 2.5 h
- 0.0 + 6.0 h
- 13.3 h
Hardware or software comes from the files a session's commits touched. KiCad and parts-site time always counts as hardware.
Tools
Tracked time only
- Claude Code58.2 h
- KiCad9.3 h
- Parts sites1.5 h
- Editors and terminal3.6 h
A minute seen in two tools counts once, in the first that applies: KiCad, Fusion, parts sites, editors, then Claude Code. Over the whole record that removes 13.4 h from the total.
Parts sites over the whole record: jlcpcb.com 59 min, lcsc.com 10 min, digikey.com 10 min, snapeda.com 6 min, aliexpress.com 4 min, adafruit.com 1 min.

All the time on that project up to the end of that date, marked on the running total above. It leaves out bench work and anything else away from the Mac, so treat these as minimums.
How this is measured
I would rather undercount than pad. Every total here is a set of distinct minutes, so overlapping tools and parallel sessions can't inflate it. Nothing is estimated or backfilled.
Where the minutes come from
Claude Code sessions, since 30 Sept 2026
From the session logs, matched to a project by folder. Gaps up to 10 min between messages count, so this includes waiting on it. It measures how long the session was open. Zeno's own replies aren't counted, only time I spend building him.
Tracker, since 3 Oct 2026
A small app samples the front window for KiCad, Fusion, editors and terminals. A sample idle for over 2 min doesn't count.
Parts sites
Time on a short list of suppliers' sites, credited to the project active in the 60 min before. That guess can be wrong, so none of it counts toward this website.
Logged by hand, 10.5 h
Entries I wrote down myself, always shown hatched and never mixed into tracked time.
Commits
Non-merge commits on all branches. Line counts aren't shown, because KiCad files are generated and would swamp them.
What it misses
Anything before tracking began, unless it's in the logged column. Project start dates are not when these numbers start.
Work away from this Mac: the bench, soldering, reading on paper or on my phone.
Time the tracker saw but couldn't tie to a project. It stays out of every total here.
This website: some commits have no tracked time around them. A commit-based estimate puts that at about 8.3 h. It isn't counted, so that figure is low.
Work on the tracker itself, which isn't one of these projects.
How much of the work the tracker saw, as commits made during tracked time on that project or within minutes after it: Jot 145 of 145, Handshake 13 of 13, This website 119 of 155, Zeno 47 of 47. A low number means real hours are missing from this page.
Stops at the last complete day, 14 Nov 2026, so it can read lower than a project page's live counter.
