Fresh hacks every day
[Rich] over at NothingLabs has put together a really cool laser light show that you really must see in an effort to win a laser cutter from Instructables. His walkthrough discusses the mechanics of laser light shows - specifically how galvanometers are typically used to precisely aim mirrors in order to draw images and write text. Commercial galvanometers tend to be pretty expensive, so he … [Read more...]
If you haven't seen the news already, prolific maker [Limor Fried/Ladyada] is set to grace the cover of WIRED magazine in the upcoming April edition. Not only is it a great day for the hacking/maker community as it puts a bright spotlight on the things we do every day, it's a big day for female engineers as well. While WIRED has been around for 18 years as of this past January, this is the … [Read more...]
[ProtoDojo] wanted to play a racing game on his iPad, but he was not a big fan of using the touch interface for this particular title. Instead, he put together a pretty neat little hack that allows him to play games on his iPad using an old NES controller. He built a set of custom conductive arms which he mounted on three micro servos. The servos were attached to the iPad screen using small … [Read more...]
This is a hack in the finest sense of the term. It not only allows you to capture data from an analog oscilloscope for later analysis, but provides you with a great tool if you're posting on the Internet about your projects. [J8g8j] used an empty cashew container to add a camera mount to the front of his scope. This is possible because the bezel around the display has a groove in it. A bit of … [Read more...]
[wesdoestuff]'s mother needed a clean way to mix together fragrance oils. Being the stand up kinda guy he is, [Wes] threw together a few spare parts to make this Magnetic Stir Plate. The whole setup is amazingly simple. Pry the fins off of an old computer fan, glue a couple magnets to the fan's hub. Drill a hole for a DC connector, find some sort of cover and.. Bob's your uncle! [Wes] advises … [Read more...]
We have seen Kinect used in a variety of clever ways over the last few months, but some students at the [University of Konstanz] have taken Kinect hacking to a whole new level of usefulness. Rather than use it to control lightning or to kick around some boxes using Garry's Mod, they are using it to develop Navigational Aids for the Visually Impaired, or NAVI for short. A helmet-mounted Kinect … [Read more...]
We still can't figure out why a standard charging scheme hasn't been developed for handheld devices (other than greed). Certainly we understand that many devices have different electrical needs as far as voltage and current are concerned, but we still long for the ability to use one charger for many different doodads. [Rupin] is trying to narrow down the number of dedicated chargers he uses by … [Read more...]
