Printing A RepRap

repstrap

The RepRap project has been working on bringing 3D printing to the masses by creating a extrusion printer that can also make the majority of its own parts. For the most part, these print ABS or HDPE plastics which are strong and recyclable. In order to create these replicating printers, similar machines called RepStraps are built out of either laser-cut parts or machined elements. They are functionally equivalent to RepRap printers, but are not made of printed parts. [nophead] documented his RepStrap, HydraRaptor, that is based off a milling machine. He had already printed a set of RepRap parts, and he documented printing a second set. The machine worked for about 100 hours over the course of 2 weeks, printing about 1.5 kg of parts. He made a few adjustments, such as replacing ABS bearings with HDPE to reduce friction. The parts are for Factor e Farm so they can get started with 3D printing.

Archie The Helper Bot

We noticed this article on BotJunkie about Archie the helper bot. Archie is supposed to help out around the house with cooking, cleaning, and other mundane tasks. [Evan] makes a very good point though. Why do people insist on putting creepy heads on their robots. They aren’t making them any more endearing, it’s just creepy. While that is a very astute observation, we would like to add some more. Watch the video above, and study the image after the break. Archie doesn’t seem to be a functional bot. He never moves in the video under his own power. The scene where they “walk” him along is comedy gold. His head keeps falling backwards,or possibly off. And what use is a helper bot that doesn’t have actuated hands? The video is in German, so maybe we’re missing something. Maybe Archie is a mock up or a joke and we just needed translation.

Ceiling Fan POV

We know some of you are getting sick of POV projects, but this one was just so cool, we couldn’t resist. [UncleBone] thought POVs were pretty cool, and wondered if he could use one on his ceiling fan. It would have been a breeze just to toss something like the RGBike POV on there and call it finished, but he designed his own. Opting to blow away the norm of using a single row of LEDs, he chose to do 5 different rows of LEDs, one for each blade. The whole thing is controlled by an Arduino, with a spreadsheet for image manipulating. Unfortunately, we don’t see any source files for the project available. Maybe he’ll put them on there if we ask really nicely. If he could get it playing animations, we would just chill and watch it for hours.

[onezerothrice] has been working hard on creating ARtisan, a flash library for bringing augmented reality to the browser. His goal in creating the library was to make AR projects quicker and easier to develop. The library can provide the location, size, and rotation of multiple markers on screen with little work from the developer. It is licensed under the GPL and comes bundled with Papervision3D, another flash library for manipulating objects in 3 dimensions. He has posted several demos with source and accompanying video.

The Pwnie Awards are an annual event at the Black Hat security conference in Las Vegas. They award the Golden Pwnie in a variety of categories: mass 0wnage, most innovative research, most overhyped bug, most epic FAIL, and our favorite: Best Song. Embedded above is [Paco Hope]’s 50 Ways to Inject Your SQL. While a strong entry, it doesn’t touch last year’s winner Kaspersky & Me: “Packin’ The K!”.

Gentle Safe Cracker

Safe_Cracker2 (Custom)

[Carlito] found a safe in his garage with mystery contents. It shows signs of attempted entry and makes interesting noises when shaken. What is the best solution to find out what is inside? Hack it open? Smash it? Blow it up? No, the best solution is to build a robot to try brute force cracking. The robot, housed in an old power supply case, is little more than a servo and a servo controller, communicating with his PC via USB. It seems like a good idea though. Unfortunately, he found it to be seriously lacking in torque, so he’s waiting now to upgrade. The contents of the safe are still a mystery.

4D Systems Micro Drive

4D Systems micro drive provides both raw and FAT level access to microSD cards. The module contains a dedicated host controller that transforms what may be an otherwise intimidating card spec into a group of simple serial commands. With a wide supply range of 3.6-5.5 and .1″ lead spacing, this should be cake walk to tinker with. The device doesn’t support FAT32 yet. According to the GOLDELOX-DOS command set page 9, “FAT32 is currently not supported, if you mount a FAT32 formatted disk, you will not be able to access it at all, both FAT and RAW commands will fail”. At the moment the device seems limited at 2GB FAT16 partitions. This sure does seem like cheating after implementing SPI and Nibble mode SD card protocols.
