What I find frustrating about domino toppling is its ephemeral nature. If only the dominoes could stand themselves up again, you could topple them over and over. Los Angeles artist Karl Lautman solved this problem a few years ago in his sculpture called Ouroborus.
I blogged last week about how microcontrollers like Arduino and Basic Stamp are changing the way sculptors use computers to create works. In Ouroborus, each domino is connected to a solenoid beneath it via a couple of polyester strands. When the domino falls over, it lifts the solenoid's plunger a bit. When the solenoid is energized (under microncontroller control), it pulls the plunger back down, yanking the domino back up. I've attached a drawing of the domino hardware.

When I got an iPhone 8, I was amazed at how much better the camera was than the one on my iPhone 7. I didn’t buy an iPhone XS, but its camera was a lot better than the iPhone 8’s. Austin Mann’s review of the iPhone 11’s camera makes it clear that its camera is […]
When it comes to data analytics or deep learning, there’s one language behind the apps and algorithms that power the biggest companies of today: Python. The best part about this tool is that as versatile as it is, it’s actually fairly easy to learn. But mastery? For that, you need more than just a beginners’ […]
Your smartphone’s GPS is a modern necessity for some trips, but how do you use it safely? It’s been a problem ever since phones went mobile. A certain phone mount even shelled out the money for a commercial during the Big Game, so clearly there’s a market for the solution. Turns out there are a […]
