While searching for property around Indy, I found where people are playing Tic-Tac-Toe. Underwhelming, I know. It gave me a chuckle.

One of the first things I did, as a kid learning to sew, is figure out how the lock stitch worked on a sewing machine. You had a bobbin of thread in the bottom and the machine wrapped the top thread around it without getting tangled up (for the most part.)

This image is the best explanation I have found for the process. Very cool to see how it works. The bobbin is feeding out the blue thread and the main green thread comes from the top. Compare this image to your sewing machine and you will be able to identify the portion around the bobbin that fills the role of the red section in that animation.

Here is the most ambitious thing I’ve made with a sewing machine.

This is one of the cooler images I have seen in quite a while. A couple million dollars and you can create you own little tornado too. But, the F16 is an expensive method of drying the tarmac.

This also shows why FOD is such a risk. Here is a higher resolution version of the image taken by Keith Blincow. I haven’t been able to find a home for Keith.
