Understand technology.
Use the possibilities.
A workshop on the web. This is where the tools live that I need myself: a MIDI generator for the DAW, a solar panel straight from my own basement, a one-shot clipboard between two computers. Everything runs in the browser – no account, no cookies, no server where none is needed.
Tools I actually use myself.
Not a portfolio, but a shelf. Every piece here is in daily use – at my desk, in the DAW, in the basement or between two computers.

MIDI PERFECT 5
Five lanes – drums, bass, chords, arp, melody – play live from a chord progression into your DAW. MIDI import, tablature with chord diagrams, Cubase sync, SMF export. One HTML file, no build.
02 / EnergySolar·Live
My own PV system in real time, pushed from Home Assistant to the network edge – without opening up the home network.
fixcopy
Text or a screenshot from one computer to another: send it, enter the four-digit code, done. It appears exactly once and is deleted in the process.
04 / DMSELO Distribution Workflow
Starts a workflow from an ELO template and distributes it to users automatically by email. VB.NET against the ELO Indexserver – open source.
05 / PlaygroundBrowser signature & drawing studio
What your browser gives away about itself – drawn as a seal, computed locally, never sent. Plus a drawing board with an easter egg.
New
Two pinball tables in your browser
Invasoren and Schafschiesser: pinball classics from 1979/80 as engineering drawings – real physics, fullscreen and a high score list with three initials. Plus Asteroiden and Klickbumm.
For more than 25 years: systems that still have to run tomorrow.
