Fresh hacks every day
Electronics are undoubtedly the basis for our modern society. Leaving out transistor-based devices, and a mechanical clock would be one of the most intricate devices man has come up with. As a Mechanical Engineer, I thought it would be a fun challenge to design and build my own gear-driven clock.
Because clocks have obviously been invented, I wouldn’t be starting … Read the rest
Here’s an art exhibit that does its own painting. The Senseless Drawing Bot (translated) uses the back and forth motion of the wheeled based to get a double-pendulum arm swinging. At the end of the out-of-control appendage, a can of spray paint is let loose. We’re kind of surprised by the results as they don’t look like a … Read the rest
[Frank] sent in a link to this fantastic wooden clock. The design was dreamed up by [Clayton Boyer] and he’s got full-sized templates for sale on his site. We’ve marveled at his creations in the past, having featured his useless machine that was made from wooden gears. This “Bird of Paradise” clock steps up the complexity quite a bit, … Read the rest
[Stephen Hobley] has been experimenting with an electromagnetic pendulum in order to build himself a clock. Through the course of his experiments, he has learned quite a bit about how pendulums function as well as the best way to keep one moving without the need for chains and weights, which are typically associated with these sorts of clocks.
His … Read the rest
Put a case around it and it would be a grandfather clock but for now it’s a pendulum clock made from LEGO pieces. The video after the break shows a great overview of the build. You can see the workings at several different angles, as well as a clip that has been sped up to show the movement of the … Read the rest
The robot above can balance an inverted pendulum. But wait, it gets better. It can balance an inverted pendulum that is articulated in the middle like the one seen above. Wait, wait, wait… it gets even better. It can start with the pendulum hanging below the sliding carriage, flick back and forth to get the two segments swinging, and … Read the rest
[Tom Shannon] uses science as part of his art. One of his methods when painting is to use this radio controlled paint pendulum. He gave an interview at his studio, which we’ve embedded after the break, and goes into detail about this device. It has six different reservoirs that hold the paint colors. Each gravity-fed canister connects … Read the rest
