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.
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?
A beautiful trail high above the timber line, spectacular views over the Saas Valley in Switzerland, this is the “Almageller Höhenweg”. The Saas Valley is located in the Canton Wallis in Switzerland, on the border to Italy.
Part of the hike is not for faint-hearted, but very spectacular.
Among the many wonderful things that nature can provide, I love to watch damselflies flying above the water. It is pretty hard to catch one of these insects, but today I was lucky to capture one of these shiny predators:
Damselflies are similar to Dragonflies, but smaller and have slimmer bodies.
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!
Fantastic view to the South today on a hike around the ‘Engelstock’:
The snow covered Swiss Alps in the background with Ingenbohl-Brunnen and Lake Lucerne in the middle and Lake Lauerz on the right. If you want to see the view from the peak (Mt. Hochflue) on the right, see this post.
It has been snowing down to the lower areas in Switzerland the past days: Winter finally arrived in my area. So I consider last weekend the ‘weekend before winter’, at least in a meteorological sense. And because it was a wonderful ‘inversion’ situation with fog below and sunny sky above, it is a good time to share a few impressions.
