I’m so thankful, that the Jane and Aatos Erkko Foundation is supporting my research on acoustic 3D printing. Their grant gives me the opportunity to dive deeper into acoustic 3D printing and develop new applications.I’m further thankful for the support of the University of Helsinki where I can perform my research for the next years.…

My nephew wished to get a toy signal for his toy cars in his toy city. I think that is a nice challenge, and today, I have time to continue the prototyping.

Want to know a cool trick how to animate diagrams and add cool effects with PowerPoint. Watch my short clip on youtube: 🌐https://youtu.be/jqb_jbkh2LA The first step is to export the diagram as a *.wmf file. This works from many programs, such as MATLAB or Origin. If *.wmf is unavailable as a document type, *.emf also…

I finally found the book I had missed since starting my doctoral studies. The funny part is that I never lost it. It had been standing in the library for all the years, and I just did not know its existence.

Each new year comes with new regulations. One regulation that is not much talked about is the EU Directive 2019/882. It is the European Accessibility Act (EAA), and it will come into force by national legislation, at the latest on 28.06.2025. You will notice its effect, as it defines the accessibility of all websites as…

You may be wondering what this construction is used for. When you work in the field of ultrasonics (in water), it is pretty common that you need to get rid of some air bubbles that adhere to some surfaces. This tool can flush them away with a jet of water. I have already built several…

These 3D-printed eye diagrams can be used to visualize the size of digital signals on cables. I prepared them for a lecture related to signal integrity. The files are also available on 🌐https://youmagine.com/designs/5f74a596-ee1f-4c5b-bf0d-091f445306e6 These scale models are based on eye diagrams of several digital communication systems, including USB and HDMI. They can be used to…

I’m sure you know what an IGBT is, but did you know this small device could already save an equivalent of more than 3 years (sic!) of annual global CO2 emissions? Today, I had the honor to listen to the lecture of Professor Bantval Jayant Baliga, the inventor of the IGBT. When he built the…

Are you working in science and need to report quantities based on the SI system? When I rehearse presentations with my students or review their reports, I often notice that they need guidance in formatting and typesetting SI quantities properly. I must admit that my years in metrology have made me examine this more closely. I…
