Fresh hacks every day
[Jason Birch] just finished building a beautifully simple user interface for the Raspberry Pi. The goal was to keep it small and intuitive while still providing a range of functionality. His add-on hardware gives feedback using several LEDs and a four-line character LCD screen. It provides control using just four momentary press switches. The base for the add-on hardware is a chunk of … [Read more...]
This cube lamp was assembled using common cardboard. Not only does it look interesting, but it's basically free with every Ikea purchase since all you need is a source of cardboard, cutting implements, and glue. [Lindarose92] fabricated the shade out of narrow strips of corrugated cardboard. This particular lamp also has a cardboard base but we're sure you could use it for just about any light … [Read more...]
The device that these seamen are standing around is a US Navy targeting computer. It doesn't use electricity, but relies on mechanical computing to adjust trajectories of the ship's guns. Setting up to twenty-five different attributes by turning cranks and other input mechanisms lets the computer automatically calculate the gun settings necessary to hit a target. These parameters include speed and … [Read more...]
More than ever, 3D printers are being used for small prototype and production runs, and the normal way of using a 3D printer with a single desktop app is becoming more and more out of date. [Zach 'Hoeken' Smith] has a solution to the frustration of printing out multiples of objects: it's called BotQueue, and allows anyone to submit print jobs to multiple 3D printers over the Internet. The idea … [Read more...]
This little box not only plays tunes, but it lets you control several aspects of playback without touching a thing. [Thomas Clauser] calls it the LighTouch and we like it because it uses inaudible sound to control audible sound. We think the pair of cylinders sticking up through the top of this project enclosure will be recognized by most readers as the business end of an ultrasonic … [Read more...]
[Felix Rusu's] mailbox is on the other side of the street and he's got a pretty big front yard. This means checking for mail is not just a pop your head out of the door type of activity. This becomes especially noticeable during the winter months when he has to bundle up and trudge through the snow to see if his letter carrier has been there yet. But he's made pointless trips a thing of the past … [Read more...]
We've never really thought to ourselves "This RC car is fun, but it really needs more handguns". And if we did, it certainly would not be a built to undertake with students. But to each his own. [Jerod Michel] is a mathematician working in China. He recently built the project seen above with a group of students. Look closely and you'll notice that the remote control car includes a remote control … [Read more...]
