Do you want to use USB3, Gbit Ethernet, PCI-Express or DVI/HDMI in your custom PCB designs? This talk may be for you. Intermediate understanding of electrical engineering concepts (impedance, wave forms, digital signals) is recommended. I will use KiCAD to demonstrate concepts.\n\nThanks to the ubiquitous availability of fast electronic components, custom PCB design incorporating high-speed data transmission has become incredibly affordable. Two particular technologies are very useful for transmitting fast digital signals on a PCB: [Differential signalling](https://en.wikipedia.org/wiki/Differential_signalling) combined with [microstrip traces](https://en.wikipedia.org/wiki/Microstrip) into differential pairs. This talk presents practical aspects of designing PCBs with differential pairs, as well as why they are so useful.","original_language":"deu","persons":["seto"],"view_count":16,"promoted":false,"date":"2026-06-13T17:00:00.000+02:00","release_date":"2026-07-05T00:00:00.000+02:00","updated_at":"2026-07-05T19:15:07.046+02:00","tags":["110718","2026","cosin2026","Hardware","Lecture Room","cosin2026-deu"],"length":2983,"duration":2983,"thumb_url":"https://static.media.ccc.de/media/events/cosin/2026/110718-0048f383-4b6a-472d-9f79-c99b116369d7.jpg","poster_url":"https://static.media.ccc.de/media/events/cosin/2026/110718-0048f383-4b6a-472d-9f79-c99b116369d7_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/cosin/2026/110718-0048f383-4b6a-472d-9f79-c99b116369d7.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/cosin/2026/110718-0048f383-4b6a-472d-9f79-c99b116369d7.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/cosin2026-110718-differential-pair-pcb-d","url":"https://api.media.ccc.de/public/events/0048f383-4b6a-472d-9f79-c99b116369d7","conference_title":"Cosin 2026","conference_url":"https://api.media.ccc.de/public/conferences/cosin2026","related":[]},{"guid":"ebdcb28a-e7d6-472c-8122-e43b45c0dfe9","title":"Container betreiben mit Podman Quadlets","subtitle":null,"slug":"cosin2026-110716-container-betreiben-mit","link":"https://fahrplan.cosin.ch/fahrplan/2026/events/e26b73b4-dce6-5711-9af0-7954a96d37c1/","description":"Podman quadlets sind endlich auch auf Ubuntu 26.04 und Debian trixie in einer brauchbaren Version verfügbar.

Dazu werden zusätzlich zu den Daten der Navigationssatelliten (GPS, Galileo etc.) Korrekturdaten verarbeitet die vom Centipede-RTK Netzwerk zur Verfügung gestellt werden. Diese Korrekturdaten sind frei und kostenlos nutzbar und jeder kann eine Centipede-RTK Basisstation betreiben um das Netz dichter zu machen (\u003c1 cm Positionierung ist möglich bis 30 km Abstand zur Basis, danach nimmt die Präzision langsam ab.) [Centipede-RTK]( https://www.centipede-rtk.org/)\n\nIch habe RTK und [Centipede-RTK]( https://www.centipede-rtk.org/) an der letzten FOSDEM kennen gelernt. Im Vortrag wurde auch die Verbreitung von RTK Basisstationen gezeigt: Es gibt sehr fleissige Communities in Frankreich und Ungarn. Der Rest der Welt ist noch leer! Darum dachte ich, dass ich hier die Technologie RTK und das Centipede-RTK Projekt auf Deutsch vorstelle um es bekannter zu machen. Ich habe bisher selber RTK noch nicht eingesetzt. Habt keine all zu hohen Erwartungen an mein technisches Detailwissen :-) Im Anschluss an den Vortrag gibt es eine offene Runde um zu Diskutieren ob Centipede-RTK für die Schweiz sinnvoll ist, was die nächsten Schritte sein könnten und um die Menschen zu Vernetzten die Interesse daran haben.
