Buildable tools and devices: what they do, what you need, how to build or use them, and a worked example. The interactive ones open a tool.
Buildable Instrument
The Servitor Ledger
A local record of constructs, feedings, readings and closings, exportable as a plain text file.
What it is
To keep a working auditable without keeping it in your head.
At a glance
- Inputs
- A construct name; an event (created, fed, read, closed); a note; a timestamp.
- Outputs
- An append-only JSONL file and a weekly summary.
How to do it
- Create `ledger.jsonl` and add one line for the construct's creation.
- After every feeding or reading, append a line with the date and a short note.
- At the close, append the close line and set the construct's status to closed.
- Once a week, read the last seven lines for each open construct.
- If a construct has no entry for two weeks, close it or explain why.
What you need
- A text file
- A script or a notes app
- A weekly review
A worked example
A line: {"ts":"2026-11-07T09:12:00+11:00","construct":"VEL-ETH-8","event":"fed","note":"one minute, Mercury hour"}. The weekly review shows three feeds and no result; the practitioner closes it early.
Variations
- Use a SQLite table if you want queries.
- Add a `result` field and count how often a construct's task actually happened.
- Keep one ledger for all constructs, with a `construct` field, rather than a file each.
Code sketch
This is a sketch, not a runnable program. It names the shape of the automation; the definitions are yours.
const line = { ts: new Date().toISOString(), construct, event, note };
await fs.appendFile('ledger.jsonl', JSON.stringify(line) + '\n');Related entries

The entries either side of this one in the same section.
- The Digital Banishing Switch One action that closes the working: closes tabs, clears a cache, logs out and returns attention.
- The Correspondence Engine A small table and query function that maps Grimoire aspects to technical patterns.
- The EVP Session Kit A timer, a noise source and a log for a recorded listening session.
- The Random Rite Generator Composes a one-sitting working from a seed, an aspect and a small library of actions.
- The Planetary Hour Daemon A small background process that knows the current planetary hour and prompts the working that belongs to it.
- The Sigil Forge Turns a sentence, a Grimoire aspect and a seed into a deterministic sigil, a charge card and a record line.
New entries, when they land
Occasional notes when a section of the grimoire is added or revised. No account, no tracking across sites, and one line to leave.
