After installing several nest products and a ring doorbell, I just completed the next step in my home automation: the rain machine wifi enabled sprinkler controller. It uses weather information to save water. And I can control it from my phone!

Bryan Whitby, who contacted me earlier to tell about very cool USB chess board projects, contacted me recently with a very generous offer to use his awesome chess graphics in Chess for Android. I am very thankful, since these graphics look really good, and combine well with the various board types already supported. So, expect an updated on Android Play and my website really soon! And, thank you Bryan!

Because we bought a house in Saratoga and are busy renovating and moving in, I have not been very active with my usual hobbies, including the Micro-KIM tutorials. But as soon as things settle, I will be back!

I happened to be in Groveland, CA at 8/13 and was hoping to see the Perseid meteors. Unfortunately, not much action, but at least I got this moonshot.....

Idea for a small Android programming exercise: write a simple 2D physics engine that models balls being shot up with random velocities and then accelerating down, while bouncing against the walls in a finite environment. Then extend the world with different objects, such as balloons that float steadily up.

Please don't forget I am posting a series of tutorials on programming the Micro-KIM. In recent postings, I showed how to adjust the brightness of the LED display, a technique that can be used in a wide variety of demos, such as fading the display in and out, sliding a glow effect over characters or segments, or giving emphasis to parts of the display.

The fourth tutorial in the series on the Micro-KIM has been posted. Here we are going to take control of the full LED display with custom-made characters and explain how to avoid flicker.
