The board on this page is a live, toy auto-placer: parts find each other the way a first layout pass should. It is the kind of thing this lab is for.

What’s on the bench
Each part of the lab will get its own subdomain as it comes online. Nothing below is live yet; this is the plan, in the open. More about the lab.

Instruments for the browser
First up: Heaviside, a circuit simulator that runs entirely in the browser. Drop parts, wire them, watch the waveforms. Nothing to install, nothing to sign into.
Planned tool codenames: HeavisideNyquistBode

Notes from the bench
Write-ups on what worked, what didn’t, and the math behind both. Short field notes, plus the occasional long read when a problem earns one.

Invite-only betas
Early builds of tools before they are ready for daylight. Rough edges included, feedback very welcome.
