Fedora Rawhide Nightly Builds

fedora_rawhide

The devs over at the Fedora Project are hard at work on the development version: Rawhide. They’ve just setup automated nightly builds of the liveCD which can easily be downloaded and tested on a CD, DVD, USB drive, virtual machine, or separate partition.

Rawhide will be released as Fedora 12 upon completion.  With this version you have a choice of Gnome 2.28 or KDE 4.3 for your desktop.  There is also improved power management, expanded support for mobile broadband, easy bug reporting, and many more new or improved features. So roll up your sleeves, download last night’s build, and help test some open source software.

Bliplace LED Toy

These wearable LED toys called Bliplace are freshly made and headed to Burning Man. They’re pretty much just a sound reactive toy, but [Tanjent] decided to go pretty in depth in the design. They are 1″ wide octagons with 3 super bright LEDs and a microphone. The microphone is sampled at 4400 hz by the ATTiny25v and the signal is split into high and low frequency streams. The center LED is low frequency, the sides are the high. They can run a full week on a battery. He’ll be handing out 350 of them at Burning Man, then releasing the source code, boards, and kits after that.

RepRap Wedge

Generation 2.0 of RepRap, the self replicating 3d printer, is approaching realization. Code named “Mendel”, the new design will be wedge shaped rather than a box which offers a few benefits. The overall design is smaller than the original RepRap but the printable area is larger. This means more functionality with less building material. With each new generation of this project the assembly gets easier and total parts price drops making the RepRap available to a much wider audience.

The RepRap blog has put forth some design specs, a picture of the assembled prototype, and has links for general assembly information (ZIP). We won’t see a finished version of this released for a few months but so far it looks like a big leap forward.
