Bottle glass cutting and polishing.
Hi, nice project. Thank you for sharing. I am wondering why you are using shift register to get 8 outputs when the UNO has 14 IO pins.

Thanks for the prompt reply ) I'll ask around at our fb pottery community for the kiln schedule which would allow to catch this sweet spot and prevent overheating - you can't really see what's happening inside the kiln until it cools off.
Thanks for the tutorial, I have a couple of questions:1) with this setup, would you go for an angle cut (say, at 45 degree)?2) you mentioned using a kiln for finishing the cut, I do have a kiln, would you just 'warm' it enough to get close to the fusing?
I would not go for an angle cut. First is the difficulty in scoring the glass at an angle that is not constant around the bottle. Breaks in glass like to take the path of least resistance and since wine bottles have uneven wall thickness you have much greater chance of wandering breaks. Since glass, unlike porcelain, will melt into a puddle, the temperature in the kiln and timing is critical, the good thing is that the cut edges are sharp so they heat more/faster than the main body of the glass, as soon as they start to melt lower the temperature. Half melted bottle can be cool but glass puddle is usually not unless you are proficient in glass blowing.
Nice job. I did one of those about 10-15 years ago. It still sits in the corner of my garage and every few months, when I need compressed air, I power it up. No maintenance so far, when the pump fails I'll just replace it. I used a 1 dollar clear plastic fuel filter on the air intake. The thing to look out for is that standard cheap air compressor pressure switches have very small hole to decompress the pump so it is not under pressure when it starts. When you have low CFM pump like from a refrigerator it will seriously delay the time it takes to reach full pressure. I blocked that hole and installed electronic blow off valve.

Interesting build. :)I have built 2 small wind turbines, using stepper motors, on my grandparents farm. All they did was charge few laptop batteries (built into the windmill) and turn on 10W halogen and 5 watt LED spotlight (respectively) when they detected movement after dark. While they were in place they worked perfectly. I limited them to about 300 degrees turning. The first windmill blew off the pole in a storm 3 months after installation but was found in a nearby field. The second one, slightly bigger with sturdier mounting, lasted 6 months before disappearing completely after another storm. I used PVC pipe blades and had no problems with the blades. When you go to solar cells be aware that the whole panel will not produce more electricity than the weakest cell in it and for maximum efficiency it should point directly at the sun. Therefore it is very important that the panel is completely free of shadows and it should pivot to follow the sun. :)
