I'm Martin, a Linux tinkerer from Stockholm, Sweden. Small Bash tools for Debian, often involving Dell hardware that refuses to cool itself — plus a self-hosted bookkeeping app, a maintained Docker image or two, the occasional PowerShell fix for a Windows annoyance, and lately SwiftUI apps for the iPhone and the Mac.
Self-hosting
- firmabok: Swedish bookkeeping for sole traders (enskild firma), self-hosted on your own network without cloud dependencies
- docker-observium: unofficial Docker image for Observium CE — rebuilt weekly for amd64/arm64, mirrored to Docker Hub
- observium-ce-archive: keeps every Observium CE build around, since upstream only ever publishes the latest one
- dietpi-factory: deploy preconfigured headless DietPi from one wizard profile
Tesla
- WallConnectorLog: self-hosted logger for the Tesla Wall Connector Gen 3 — the charger keeps no history, so this polls its local API around the clock and derives real charge sessions, with a Grafana dashboard included
- teslamate-maintenance: the maintenance chapter of the TeslaMate docs as one interactive menu — verified backups, guarded restores, closing or deleting drives and charges, PostgreSQL major upgrades
Apple
- EVLog: native iPhone client for your own TeslaMate server — drives with route maps, charge curves, statistics and battery health, reading only from machines you run yourself. On the App Store
- WallConnectorLog for iOS: the iPhone companion to the WallConnectorLog server — live charger status, the sessions it has derived and the charger's lifetime counters, with a demo mode a typed word away. On the App Store
- Debris: Mac cleaner that finds what is left of apps you no longer have, uninstalls apps together with everything they own and clears caches — it shows the list first and moves things to the Trash rather than deleting them. Download · debris.martinstockzell.se
Keeping Dell machines cool on Linux
- dellfan: fan control for Dell OptiPlex desktops — detects what the machine supports and sets it up
- dell-bios-fan-control: toggle SMBIOS automatic fan control on Dell machines
Debian host tooling
- hostctl: one command to update, inspect and manage your hosts
- geodebtest: autodetects your location and benchmarks your country's Debian mirrors
- update-fastfetch: keep fastfetch up to date on Debian without waiting for the repos
Windows
- no-new-outlook: removes new Outlook and keeps it from coming back
- TPFanCtrl2: fan control for ThinkPads, carrying on the archived TPFanCtrl2 line
