The RepRap project, which is a printer that can make components using rapid prototyping technology, and it is designed so that it can eventually self replicate. Has released a new breakout board for the Sanguino that provides access to all the pins as screw terminals. The Sanguino is an Arduino compatible board based on the ATmega644P chip. You can populate the full board with all the components and have a fully functional single board. You could populate only the screw terminals and plug your Sanguino, and use it as a breakout board as well. The board design is released on Google Code.

We wrote about [Chris Anderson] before when he released the Arduino based autopilot. He has since crashed his first Predator UAV, due to an underpowered motor and poor control of the v-tail only steering. He has since released a pro version of the autopilot controller, and is modifying this UAV Predator drone kit to work with it. One ATMega168 processor handles flying and the other handles GPS navigation, but because they work together, it results in a fully autonomous drone. He also has a BlimpDuino version we have covered before.

[Joe L] sent in the Arduway on the tipline. It is a robot made of Arduino and Lego NXT components based on the Segway. A software library to control LEGO NXT motors and a few sensors he used is available on SourceForge. This robot does a good job of balancing itself while moving forwards and backwards.

There is a YouTube video of it in operation after the break.

This PICBASIC complex LED matrix solution was developed by [Olivier de Broqueville] to drive a matrix of LEDs. Using some cheap transistors, common red LEDs, and a PIC16F628, he is able to drive a 6×6 LED matrix. This project is very well documented and has everything available including: circuit board layouts, schematics, PICBASIC source, VB computer interface program, and parts list.

If you weren’t looking forward to trying to find a NES Four Score just to rip connectors out of it or were reluctant to cut the ends off your NES controllers and use different connectors for your NES hack, you’re in luck. Parallax has released an NES controller connector (7-pin, male) that is compatible with the Nintendo controller. They also provide the socket pinout. It’s interesting to see a product like this come out so long after the original console, a testament to the popularity.

Normally case mods are all show and no go, but [Fredrik Perman] and [Michael Stabile] took their old render farm and made it a working showcase for the front lobby. This is a perfect combination of function, beauty, and practicality. It is a great conversation piece, allows easy working access, and provides a tremendous space savings in one sweet looking wall-mounted case. The frame is aluminum, the back consists of sheets of polished diamond plate, with a clear acrylic sheet for a cover. The case sides are left open to allow the blue LED fans to circulate air. Cooling a render farm crammed in a closet can be quite difficult, but isn’t a problem with this open design. This build is also much prettier and maybe more manageable than the setup in ExtremeTech’s Build Your Own Render Farm article.

There are a few more pictures after the break.

RGB just got a lot brighter by using 3x60Watt flood lights instead of an LED. The bulbs are driven via TRIACs and the whole thing uses a remote control to change the levels of the three bulbs. It is also able to store these levels for later recall. The IR receiver was taken from a dead TV set along with its remote control, or a universal remote set to a Phillips TV can be used. The source code and schematic for this project are available.

This IR receiver based on ATtiny13 microcontroller is used to control a Media Center box via a remote. The circuit is powered by 20 pin ATX connector pin 9 “+5VSB” because it is the only pin that is powered when the computer is off, or in standby. The receiver is programmed to accept the codes from the remote by holding down the switch while pressing the remote button. The circuit can use “Girder” or “PC remote control” as controlling software on the Media Center.
