I was really excited to hear about the latest edition of the MakerBot 3D printer. Called the Replicator, it features all the recent improvements announced over the past year such as dual extruders and the interface controller.
This idea fascinates me — an open-source, DIY multimeter. This video, from the EEVblog, serves as more of a brainstorming session on what it would be like to rebuild a tool from the ground up with the features you want. [via Dangerous Prototypes]
A man-in-the-middle attack on HDCP-secured video links is demonstrated. The attack is implemented on an embedded Linux platform, with the help of a Spartan-6 FPGA, and is capable of operating real-time on HD video links. It utilizes the HDCP master key to derive the corresponding private keys of the video source and sink through observation and computation upon the exchanged public keys. The man-in-the-middle then genlocks its raster and cipher state to the incoming video stream, enabling it to do pixel by pixel swapping of encrypted data. Since the link does no CRC or hash verification of the data, one is able to forge video using this method.
MIT student Matthew Keeter designed and built this sweet little portable music player for his final project in Neil Gershenfeld’s famous How to Make (almost) Anything class. The case, a union of three octagonal prisms, is laser-cut from 5.2mm plywood, and features a five-“button” capacitive touch-sensing control panel. The music is stored on an SD card, loaded in the back of the player. The PCB is two-sided, and was cut with a robot PCB mill. All source files are provided.
I think we’ll see many open tools like KiCAD and gEDA (and now EAGLE) all supporting the importing and exporting of data for more sharing. I’m also looking forward to visual diffs as services like GitHub add more features for hardware.
This Arduino Leonardo clone by Inigo Zuluaga is the latest example of PaperDuino, where an Arduino is created using a paper printout as a wiring diagram, bill of materials, and construction pattern. [Via Dangerous Prototypes]
One of the many cool open source initiatives we’ve been keenly following here at MAKE is the Open Source Ecology project and their Global Village Construction Set (GVCS). They’ve been on our radar ever since they won our Green Project Contest at the beginning of the year.
