Today's theme is staying cool. I thought I would like to bring the microprocessor platform that I introduced in my last video on a field trip to my favorite place in our town.

This is Masanobu Shrine in the mountains of our town. It commemorates somebody who over 150 years ago, when the Chikuma River was frequently overflowing its banks and destroying crops, marshaled people from the town to clear some new fields in the mountains. There are apple orchards, my favorite blueberry patch and many other wonderful places up here, but what brings me up here very frequently especially in the summer, is the temperature differential. I thought I would like to demonstrate this using the little microprocessor platform that I have jerry rigged together with electrical tape.

When I left the house, the temperature that I recorded, albeit in the car, before I started up the mountain was 39 degrees celsius (102 degrees Fahrenheit). Our house is at 380 meters in elevation and 15 minutes later I was at the spring starting to collect water and the temperature was showing 32 degrees celsius (90 degrees Fahrenheit), a differential of over 5 degrees celsius (10 degrees Fahrenheit) and an elevation change of about 450 meters or 1,500 feet.

Later on in my hike, the thermometer got more acclimated to the temperatures and showed a cool 23 degrees celsius (76 degrees Fahrenheit).

This place is offers natural air conditioning and incredible hikes and forest bathing opportunities. It's where we collect the water to make our coffee, so it's a very special place to me and I'm glad to be able to bring you up here.

I hope that you will continue to follow along in the exploits of my little crude microprocessor platform and look forward as always to hearing what you have to say your ideas.
