Fresh hacks every day
This robot doesn’t know if it’s a walker or a tank. It’s the brain-child of [Marc Hamende] who works as a mechanical engineer by day and mad roboticist at night. The best place to find full details is by digging into the long thread he’s been posting to for about six weeks. It will give you a pretty good snapshot … Read the rest
Inspired by souvenir penny presses, [Robert] built the Olin College penny press. This machine stamps out coins with the school’s name and a variety of other patterns. He built it as part of a mechanical structures course, with the goal of designing something that used large forces.
Crushing a penny takes about five tons of force. To deliver that … Read the rest
[Christian] is learning to use the metal milling tools at what we assume is his local Hackerspace. We love this about the communal spaces, they provide so many opportunities to delve into new fields. He embarked on a voyage that included visits to most of the machinery in the shop as he build his own carabiner with a magnetic gate… Read the rest
Pick and place machines are marvels of modern technology. They the can lift, orient, align and drop tiny electronic components onto a circuit board that is headed for the reflow oven. On an industrial scale they move so fast it’s a blur in front of your eyes, and they use imaging to ensure proper placement. But that kind of specialized … Read the rest
[Denha's] been building marble machines for years and decided to look a back on some of his favorite marble-based builds (translated). There’s a slew of them, as well as some thoughts about each. Our favorite part is the digital simulations of the projects. For instance, the image above shows a flip-flop marble machine that was built in a … Read the rest
[Limpkin] picked up a beautiful painting of Budda while in Bali because he thought it would react well with different colors of lighting. His overall goal was to create a picture frame with built-in LEDs. The major design specification for the project was to provide an indirect light source that would not shine in the viewers eyes. He got … Read the rest
[etgalim] works in Solidworks extensively and wanted a more intuitive way of rotating objects onscreen. To do this, he created a mouse that responds to rotation. He put a 3D compass module inside an old mouse and wired it up to an Arduino. The Arduino then relays the I2C sensor data to the computer. So far, he has a … Read the rest
