Open Day in Garching

Time for another Open Day at the research campus in Garching (‘Forschungscampus Garching’). Once again, around 40 research institutes and companies on the campus will open their doors on 3 October from 10 am to 5 pm and once again I am taking care of the website of the event: https://forschungscampus-garching.de/.

Munich Quantum Valley (MQV) will be present with a booth at the Walther Meißner Institute (WMI) and Build Your Own Particle Detector (BYOPD) will be present at the ORIGINS booth .. along with lots of other activities, exhibits, projects to explore.

It took some time, but now I finally managed to finish the next twist in Particle Twister.

My game idea that I designed and realised together with Katarina Anthony during my ‘more active’ time at the ATLAS Experiment at CERN finally got the first set of long-promised playing cards for additional fun and challenges in addition to the classic spinning wheel – all that in my brand new Progressive Web App (PWA).
You can use it online at and install it locally from https://particle-twister.mehlhase.info/.

Let me know if you have more ideas for cards, playing modes or features.
I still have a few more ideas, so stay tuned for updates …

timekeeper v3

Coding, Outreach

Ever had an issue with people not sticking to their allocated presentation time at one of your events? I certainly do …

After another round of testing at our MQV Annual Meeting in Eichstätt in October, I put together a new version of my little timekeeping tool available at timekeeper.mehlhase.info.

I usually have it running on a Raspberry Pi using Chromium in kiosk mode and use chroma keying on an ATEM Mini Pro to overlay the presentation source with the timer display, all controlled by a tiny five-keys ‘keyboard’. But it’s a Progressive Web App, so you can install it locally on your PC, tablet or phone and hook that up your video mixer via HDMI.
