Liquid Robotics’ Waveglider is an autonomous submersible that explores the ocean using the power of the sun and waves. As Roger Hine explains at Bay Area Maker Faire 2011, the Waveglider can either traverse the waters on its own, converting the up-and-down motion of the waves into forward propulsion, or can be controlled remotely by a user with a GPS satellite link.
Fascinating video from Nyle Steiner, who reports on his experiments with simple homemade memristors made from what are, probably, Al-CuS-Cu and Al-PbS-Pb junctions. He describes the observations that led him to experiment with these systems and the results of his experiments, and then wraps up by drawing out a simple memristor demonstration circuit and demonstrating its operation on-camera.
Terence on Ikea Hacker used “spare parts” from his Utby table legs to make an uber-industrial tape dispenser and paperclip holder. The two hacks here are a tape dispenser and a paper clip dispenser. With the spare parts from the Utby stainless steel legs I made the tape dispenser with nuts, bolts, and a roll […]
Here’s something every aspiring superhero need, a wrist-mounted crossbow with a laser sight. Built in ten days from scratch by maker and laser enthusiast Patrick Priebe, the compact armament thrusts hand-made carbon fiber bolts with pinpoint accuracy.
The MintyTime Clock Kit is a fun way to add a binary clock to almost any container. It’s intended to be housed in a mint tin, such as the classic Altoids tin, but it looks great in almost any container, from a custom-designed, laser-cut enclosure to an old wooden recipe box.
The Real Time Clock Kit Parts Bundle includes everything but the casing to build the PIC-based clock designed by Sparkle Labs and featured in MAKE Volume 09. Be sure to read the article for detailed explanations of how the PIC, Real Time Clock, and LED driver all work together to make a functioning clock.
This fully functional alarm clock lets you practice defusing simulated explosives. When the red button is pressed, the clock starts a scary countdown like bombs in Hollywood movies. There are four wires across the top of the clock, and you have ten seconds to choose the correct wire to cut. Programmed with the Arduino IDE, so […]
