Electronics — M4cCrypt0

What lives here

The hardware side of the notes — builds, reference sheets, and lessons learned the expensive way. Less exploitation, more soldering iron.

[ TIP ]

Scope

Anything that involves a schematic, a datasheet, or a component on order ends up here, whether it's a finished build or a project still stuck at "power supply works, drivers TBD."

Reference

Production hardware protection circuits — reverse polarity, ESD, overcurrent, overvoltage, kickback, battery, watchdog/brownout: the seven to check before anything ships.

Builds

Nixie tube clock — 6x IN-14 tubes, power supply built, driver IC still under evaluation (K155ID1 / HV5122 / DM7441A).

[WARN]

Work in progress

This page is a living index — builds move between "in progress" and "done" as they get finished. Check the date on individual posts for the latest status.
