Teleportation by Optical Tweezers
A few months ago, I learned about optical tweezers. Basically, a laser beam is used to manipulate very small particles down to individual atoms. The laser beam is not so strong as to burn up the object, but is strong … Continue reading
Let Them Eat Football
On the internet somewhere, there have been concerns raised that America is headed for a food crisis. I don’t put much stock in that and here’s why. As mentioned in my recent blog entry (The One TEU Per Family Initiative), … Continue reading
Arduino: Once More, with Photo Import
I made this drawing by first getting a picture of the Uno (from the Arduino site) and then modifying the image of the circuit board so that only the words appear. This made it a lot easier to accurately lay … Continue reading

Arduino Park Under the Magnifying Glass
Lots of little details added. Sang is there because he will be the tour guide when the park opens. Which is still about a week away. As I look at this thing, I wonder. That 103 chip can’t have all … Continue reading

Acetaminophen (Paracetamol) in sketchup
I saw that a molecule was trending on Yahoo, and how often does that happen? So I thought, “Here’s a challenge.” I went over to the wikipedia entry on paracetamol (aka acetaminophen) and copied the model into ball and stick … Continue reading
Arduino in Sketchup: Modulate my pulse widths, those are tildes!
Since the last time I posted my work on the Arduino Uno in Sketchup Project, I have started using a magnifying glass. Lo, the minuses in front of the digital pinout numbers turned out to be tildes (ie, ‘~’ –which, … Continue reading
