Stiftklavier / Stylophone

Ein Open-Source-Lehrprojekt für Mechatronik, Elektronik und Musik – ideal für Workshops, Schulen und Maker.

Stiftklavier-Prototyp (Abb.: Fertiger Aufbau mit 3D-gedrucktem Gehäuse)

🎯 Projektziel

Das Stiftklavier ist ein praktisches Lehrmittel, um: ✅ Löten und Schaltungen zu üben (Widerstände, ICs, Transistoren) ✅ Grundlagen der Tonerzeugung zu verstehen (Oszillatoren, Filter) ✅ Mechatronik zu verbinden (Elektronik + 3D-Druck + Mechanik) ✅ Kreativität zu fördern (individuelle Gehäuse, Sound-Experimente)

Zielgruppe: Student:innen, Lehrende, Elektronik-Enthusiast:innen

🛠️ Loslegen

1. Material besorgen

Stückliste (BOM) mit empfohlenen Händlern.
Werkzeuge: Lötkolben, Multimeter, 3D-Drucker (optional).

2. Aufbauen

→ Schritt-für-Schritt-Anleitung

3. Erweitern

Experimentiere mit anderen Widerständen für neue Tonleitern.
Baue ein MIDI-Interface ein (Code-Beispiele folgen).

🔧 CI/CD mit KiBot (KiCad 10 Docker)

Dieses Repo nutzt KiBot in einem vorkonfigurierten Docker-Container für KiCad 10, um automatisch:

Schaltpläne als PDF zu exportieren
Platinen-Layouts als PNG zu rendern
3D-Ansichten der Platine zu generieren

👉 Ergebnisse: Siehe cam/-Ordner (automatisch aktualisiert bei Pushs).

Questions

How big is the Stiftklavier PCB?

It measures 57 × 38.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Stiftklavier use?

75 parts, built around the NE555D, BC846 and LL4148. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Stiftklavier KiCad files?

From the GerritMihu/Stiftklavier repository on GitHub, at the commit this page was made from: the board is Stiftklavier.kicad_pcb and its schematic Stiftklavier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Stiftklavier design in my own project?

Its repository states no licence, so its author keeps all rights: ask GerritMihu before reusing the design.
