The Grand Prismatic Spring is the largest and one of the most brilliant of the many springs in Yellowstone. The temperature of the water is around 60°C. The yellow, orange and brown colors are caused by small heat-loving microorganisms, names thermophiles. The intense blue color in the center is because of the sunlight gets scattered by fine particles in the water. Simply beautiful!

Happy Heating 🙂

Hot Spring Colors

I worked the past weekend and nights using the Freescale FRDM-K64F board with the colorful Adafruit NeoPixels (see “Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 1: Hardware“). These RGB LEDs can create beautiful colors. For for the non-geeky readers I have a more ‘natural’ one:

The beautiful colors in Yellowstone National Park (USA) are the result of pigmented bacteria that grow around the edges of the mineral rich water. I very much enjoyed it a few years ago, cannot wait to get back there.

Happy Coloring 🙂

Impressions from Freescale Technology Forum 2015

With Freescale merged into NXP, I guess this was the last FTF (Freescale Technology Forum) after a history of 10 years. Maybe it will transform into a ‘NTF’, at least I hope that such an energizing event and conference will continue in the new NXP area. I was busy with delivering my own sessions, but had time to meet and greet and see a lot of interesting stuff. After visiting the TechLab several times and after all the discussions with other embedded enthusiasts I have now many cool projects in mind :-).

So what I do here is to share some impressions with pictures and videos. It will take me weeks to absorb everything. Not to talk about the huge email backlog I have now ;-). So enjoy:
