The Hexa-Bouncer Plays Ping Pong With Itself

Keeping a ping pong ball bouncing is easy enough for a person to do, but it's a lot to ask of a robot. Electron Dust's Hexa-Bouncer tackles the problem with a six-axis moving platform, a pair of high-speed cameras, and enough processing power to figure out where the ball is going before it falls to the floor.

The mechanism is a Stewart platform, also known as a hexapod. Six independently controlled arms connect a fixed base to a triangular upper platform, allowing it to move with six degrees of freedom: up and down, side to side, forward and backward, plus pitch, roll, and yaw. This lets the bouncing surface move vertically to hit the ball while simultaneously tilting to correct its trajectory.

Making those moves quickly enough to react to a bouncing ball took some fairly serious...

I Checked the rel Attribute on 20 Platforms. Most "Backlinks" Pass Nothing

A day of curl, a browser console, and several lists that turned out to be wrong I spent two days trying to get real backlinks for a side project. Not buying them, not spamming forums — the legitimate stuff: publish an article, submit to a directory, list the product somewhere. Before

Building Decision Provenance Into AI-Assisted Data Science Workflows

I built this plugin for a boring reason: decisions in a data science project don't survive. Not necessarily because nobody writes them down — but because they were never the kind of thing anybody writes down. You tried 80/20 in August; the holdout leaked promotions, you moved on.
