This Golf Club Uses Machine Learning To Perfect Your Swing

Golf can be a frustrating game to learn: it takes countless hours of practice to get anywhere near the perfect swing. While some might be lucky enough to have a pro handy every time they’re on the driving range or putting green, most of us will have to get by with watching the ball’s motion and using that to figure out what we’re doing wrong.

Luckily, technology is here to help: [Nick Bild]’s Golf Ace is a putter that uses machine learning to analyze your swing. An accelerometer mounted on the shaft senses the exact motion of the club and uses a machine learning algorithm to see how closely it matches a professional’s swing. An LED mounted on the club’s head turns green if your stroke was good, and red if it wasn’t. All of this is driven by an Arduino Nano 33 IoT and powered by a lithium-ion battery.

The Golf Ace doesn’t tell you what part of your swing to improve, so you’d still need some external instruction to help you get closer to the ideal form; [Nick]’s suggestion is to bundle an instructor’s swing data with a book or video that explains the important points. That certainly looks like a reasonable approach to us, and we can also imagine a similar setup to be used on woods and irons, although that would require a more robust mounting system.

In any case, the Golf Ace could very well be a useful addition to the many gadgets that try to improve your game. But in case you still end up frustrated, you might want to try this automated robotic golf club.

Concrete Table Just The Way You Like It

You need a coffee table, you need a dinner table. Do you really need two tables? [Shua] thinks the answer is “no”.┬áThat’s why he built this swinging countersink table out of concrete and a aluminum.

He started by making a simple half-scale prototype. Then a larger one. Through these explorations he learned how the table would be made, what kind of weight it needed, and how the mechanics needed to be constructed for the most stable table top.

Next he designed the final table in Autodesk Revit. This is software traditionally used for architecture. Since the table was to be made from concrete Revit’s useful set of concrete tools were useful for this project.

Most of the construction process was pretty standard. However, the use of CNC’d pink insulation as a mold for the concrete was interesting. The foam is closed cell, so it worked fine and gave a nice finish. The assembly was finished with a glass top and a carpeted base that contained a surge suppressor and two outlets. The table can be seen swinging between two positions in a video after the break.

Robotic Baby Crib

This surprisingly pleasant looking crib is actually a robot, designed to keep babies quiet and happy all night long. Once inside and locked up, the baby is under the robot’s care. When the robot senses crying, it rocks gently back and forth. This should allow parents the time to catch some sleep. As pointed out in the article, the $5000 price tag is a bit steep. Especially considering the fact that you can get a much less technologically advanced equivalent for relatively cheap. How many of you hackers have babies? What hacks did you do to get your babies to sleep?
