Fresh hacks every day
If you, like us, thought that capacitor orientation only matters for polarized varieties like electrolytic capacitors you should read through this article. [Bruce Trump] looks at why some film capacitors have a stripe printed on one end and why their orientation can matter. He has an image rolled into his post showing both axial and dipped capacitors with a black stripe printed on one end of … [Read more...]
From what we've seen we'd say [Jianyi Liu] is really good at etching PCBs at home. Now you can learn from his experience. He just published a mammoth guide to fabricating your own PCBs at home. That link goes to his index page which leads to all eight parts of the guide. He starts off by mentioning that fab house boards are rather inexpensive these days. This will save you a lot of trouble … [Read more...]
[Sultan Qasim] wrote in to tell us about the work he's been doing on the Stellarino library. It's goal is to break down the coding barriers present for those looking to move from Arduino to ARM. This is accomplished by facilitating Wiring-stlye code for the Stellaris Launchpad ARM development board. Right off the bat [Sultan] mentions that the interface is Wiring-like, but is not compatible … [Read more...]
Way back in March [Ch00f] took on a for-hire project to make a suit that lights up to the music. He decided to build something based around a pulsating EL panel. He's put a lot of time and tried of a few different techniques, but he finally has a working EL panel dimmer. This is a saga we've kept our eye on. The fall seems to have been good to him, after a failure using TRIACS he managed to … [Read more...]

You can see the pulsing and color changing that go along with some Tuba carols in the clip after the break. The art installation was commissioned by the Downtown Victoria Business Association. A great big cherry tree was adorned with … [Read more...]
[Renaud Schleck] somehow got lucky enough to find a GPS wristwatch in the trash. It had a broken LCD screen so its wouldn't be of much use on that next hiking trip, but he knew it still had potential. He used the GPS module and a few other parts to build this reverse geocache box. Reverse geocache is a container that is locked, opening only in a pre-defined geographic location. We've seen … [Read more...]
[Jordan Wills] got tired of being limited to eight pixels of resolution and having jumper wires littering his work space. He set out to upgrade his Stellaris Launchpad frequency analyzer project using booster packs. You may remember the initial iteration of the project which used an 8x8 LED matrix to map audio spectrum. With this upgrade he's really putting the power of that ARM chip to … [Read more...]
