Fresh hacks every day
We like to run the newest software available. We often encounter problems and things that don't work because of this, but with open source that just give you the opportunity to contribute and make the package better. Now you can take the fun and daring of bleeding edge to your phone by installing the latest Linux kernel on the Nexus One. [Jon Lech Johansen] wrote up that eight step process to … [Read more...]
[Firestorm_x1] put together a tutorial about interfacing an analog joystick with a microcontroller. These analog sticks are easy to find; he got his from Goodwill but we've got a couple in our junk box right now. The stick uses variable resistors to report its position so it's just a matter of reading and interpreting that data. After explaining the concepts he demonstrates how to use the joystick … [Read more...]
Adafruit Industries has just added an Arduino shield footprint to their EagleCAD library. If you don't know, the Arduino headers use non-standard pin spacing. Learn to deal with it, there's too many Arduino shields in production to have any hope for a change in the future. This footprint should make it a lot easier to design your own boards. If you use this package make sure you're getting the … [Read more...]
True randomness can be hard to come by in the digital world. [Andy Green] is making it easier to get true entropy by using this random USB dongle. The Whirlygig uses a CPDL to gather data from a set of of oscillators. The oscillators have a constantly fluctuating frequency due to temperature changes; if they run faster they generate more heat which in turn slows them down. This, along with the … [Read more...]
