Transforming a Lawn into a Wildflower Meadow

This article is not about software or an electronics project. It is about a multi-year project transforming a lawn into a home and food for various species. Slugs plus a cat have played a role in this, in one way or another.

Electrical Race Car: From 0 to 100 km/h in 0.956 Seconds

Every year, the students of HSLU and ETHZ build an electrical race car and compete in Formula Student, the world’s biggest competition for engineers. A team of students and alumni wanted to break the current acceleration record of an electrical car (1.461 seconds). They achieved an incredible acceleration from 0 to 100 km/h in less than one second!

Are WLCSP the Solution during Silicon Shortage?

If you are in the electronics or microcontroller business: you very well know the problems with chip and silicon availability. What was supposed to last maybe for a few months starting with COVID-19 is still a problem in 2022: chips are not available or the price has skyrocket.

Cost-effective usage of NXP LPC804 with WLCSP20 Package

We at the Lucerne University are using NXP Kinetis micro controllers which seem to be affected by the silicon shortage somewhat more than any other devices? When looking that the usual sources, it was clear some are still available, but in a rather exotic WLCSP package. So the question is: can it be useful?

Aglais Urticae

Kleiner Fuchs (German), Small Tortoiseshell (English) or Algais Urticae is a colorful mid-size butterfly, found in most parts of Europe and across Asia. The caterpillars feed on nettles. With intensive farming and agriculture, nettles have been reduced and butterflies like this one have been impacted. With the recent trend to have more natural meadows, the population of butterflies like this one starts growing again. I hope to see more of them this year!

Happy Flying 🙂
