Main components
1README
Aussenlampe/2022/README.mdNerdstern control - v2 (2022)
This PCB contains a 12V solid-state-relais to control 230V nerdstern (outdoor lamp). A blue LED lights up when the relais is activated.
Requirements for v2.0
- 12V SSR with zero crossing
- 2x 3-pin connectors for 230V (N, L and PE)
- Molex 2-pin PicoBlade for 12V input
- blue status LED wired to 12V
Known issues in v2.0
- the ground plane connected to PE should exclude the 12V relais area
- separate copper plane on existing board to a distance of at least 5mm

Questions
How big is the Ampel2 PCB?
It measures 30 × 32.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ampel2 use?
23 parts, built around the ATTINY85V-10SU. 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 Ampel2 KiCad files?
From the netz39/space_notification repository on GitHub, at the commit this page was made from: the board is Ampel2/Ampel2.kicad_pcb and its schematic Aussenlampe/2022/nerdstern.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ampel2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask netz39 before reusing the design.
