Reprap Research Foundation: get yer Reprap parts here
Zach Smith writes:
I'm happy to bring you news today that we have gotten our incorporation papers back, and the RepRap Research Foundation (RRRF) is now an official non-profit corporation according to the United States of America. We are now working on the next stage, which is to achieve tax exemption. (If anyone is a lawyer or knows one that would like to help with this pro-bono, please have them contact us!)So, what exactly is the RRRF? Well, it is an organization dedicated to helping researchers (you!) involved in the RepRap project. The goal is to play a support role by offering research parts for sale at low prices. They will remain separate entities, but will obviously maintain a close relationship.
Buy the parts, build a Reprap, post lots of pix of what you make! Link

Homebrew CNC surface mount PickNPlace machine
Steve writes -
...[Here's a] video clip of my CNC Taig mill setup as a surface mount Pick and Place machine. It's slow, but it's more fun watching it do the work then it is to do it by hand! Notice how it picks up the parts in one orientation, and then rotates them to the correct destination orientation. It then "centers" the part in the "centering pit". Also notice the way-cool http://www.HighTechSystemsLLC.com Modular Work Holding System that holds the PCB down on the HighTechSystemsLLC.com tooling plate. It makes clamping the PCBs down a snap!PickNPlace - [via] Link.

The robot that sweats
Regine has a write up about this neat robot that sweats when you caress it -
Alexithymia is a term that means the incapacity to verbalize emotions. When some sufferers want to talk but are unable to utter the words, they start sweating to manifest the desire to communicate.The robot that sweats - Link & photos from Bios4 @ Centro Andaluz de Arte Contemporaneo.Alexitimia is also the name that Paula Gaetano, an artist from Buenos Aires, gave to her robot. It's a big blob that feels like rubber when you touch it. But it also sweats when you caress its surface. Paula Gaetano has a background in fine art but collaborated with scientists and techno experts to develop the robot. The only sensors are for touch and the only output is water that runs from a tank hidden in the base of the work.

Bike power unit, umbrella rack from sewer pipe & the art of making lifelike marionette bodies
Old is the new new...
Mechanix Illustrated 1951, Bike power!
Bike Power Unit will convert any bicycle into an honest-to-goodness motor bike in 15 minutes. It attaches to the front wheel as shown. Its single-cylinder, three-horsepower air-cooled engine provides 100 miles to a gallon. Fuel tank is at top. American Brake Shoe, Rochester, N. Y.Modern Mechanix » Bike Power Unit - Link.
Modern Mechanix 1932 -
HERE'S a hint for plumbers, or, for that matter, for anyone who is handy with a paint brush. Old sewer pipes that are not too badly battered can be painted up with decorative designs to make highly ornamental umbrella racks as shown in the accompanying photo. You can go in for this stunt on a wholesale basis and turn out a number of such racks and sell them to the people in your neighborhood. Three or four umbrellas can be deposited in one pipe.

Stream music to your Airport Express from Linux
Jason @ Hackszine writes -
It's still Alpha, but raop_play is an Airport Express client player that will allow you to send audio files, including http streams, to your Airport Express.Apple Airport Express Client Player - LinkBetter yet, there's an ALSA driver included with the package, which will make your Airport Express look just like a second audio output device. Once that's set up, you can just configure your preferred music applications to send audio straight to the ALSA raop device. How cool is that?

DIY LEGO ice cube trays
Brian @ GeekDad shows you how to make your own LEGO ice cube trays, he writes.. -
First things first: Making your own Lego ice cube trays is emphatically not cheaper than buying them straight out from from Lego. It is probably more fun, and since I wanted to learn mold-making, it gave me an excuse to buy a few materials and take a stab at it. Details after the jump.First, I ordered a pint of ArtMolds MoldRite 25. This is a two-part tin cure silicone rubber molding compound that's food-safe. I also picked up a can of Ease Release 200 to see if it made a difference in demolding.

Oakland, CAKimric Smythe - The Modern Steam Engine
Kimric Smythe is exploring the steam engine not with an intent to expose a "supressed technology" but something that can make use of varied fuels, and easily assembled parts. Few people can assemble a gasoline engine from found ,assorted parts. Much less machine them. Kimric on the otherhand ,with a pair of plastic calipers and an old air compressor assembled a working engine out of a used air compressor. The goal was to use as little custom machining as possible. Kimric did almost all the work on a drill press, using a lathe only on some deepdrilling work, but could have done it without that. The inlet valve assembly is the part that gives people some pause. He was able to use an off the shelf "whistle valve" as his inlet valve. The project took about 40 hrs but half of that was trial and error time.He built a boiler using a similar approach. The boiler produces about 3 hp at 125psi and has been pressure tested to 240psi. Much higher than required Kimric later found out.
You can see the engine running on air on YouTube.
Liam McNamara - Clockworks
Liam McNamara builds kinetic sculpture, junk art, and music making machines. In 2005 Liam assembled a group of 20+ artists to build the Clockworks Installation at Burning Man Festival. Liam will talk about how the group collaboratively designed and built the wooden clockwork using gigantic plywood gears with, wood peg pinions, and 5 bell wood peg programmable bells all powered by a gravity escapement, a wind motor made of woks and monkeys turning cranks. Why we love hacking obsolete technology how it all worked and how/why all of this was burnt to nothingness at the end of the event.Kinetic Steam Works - Steampunk Tree House
Kinetic Steam Works, established in 2005, is a Bay Area collective dedicated to steam powered kinetic art, whose mission is to explore and repurpose the artifacts of clockwork modernity. Steam powered machines, simple and intricate, blur the line between art and industry... kinetic masterpieces created during an era of diabolical innovation and gleeful invention.Sean Orlando's Steampunk Tree House, a 30' tall metal tree with steam instead of sap flowing through it's channels and a wood and metal house nestled within it. A roving veritable steam gardener, in the form of the Kinetic Steam Works will provide regular applications of steam, so that the tree's pipes puff with fluffy white scald. Inside, a veritable treasure trove of gimcracks, trinkets and tiny ephemera tucked into shelves and drawers, as well as surreal paintings adorning the walls.

Nokia 3310 LCDs re-purposed
Pyrofer is working on a great project using old Nokia LCD screens and PICs -
You can see ive managed to draw a basic map on the screen. The size of this map is limited by the ram, as the objects within have to change it cant be a rom map. There isnt enough RAM. Ive had to be very clever with ram byte handing to squeeze a large map into ram. Having static map layouts in rom isnt quite as bad.Pyrofer's Projects » 3310 Nokia LCD re-purposed - [via] Link.Anyway, im about to add movement to the player and put some basic game logic in. Then its onto maps larger than the screen that scroll. This is still the original hardware from the temp probe, no changes other than removing the temp sensor and using the single input for player control.

A Sound Way to Turn Heat into Electricity
New devices that can turn heat into sound and then into electricity @ ScienceDaily!
University of Utah physicist Orest Symko demonstrates how heat can be converted into sound by using a blowtorch to heat a metallic screen inside a plastic tube, which then produces a loud tone, similar to when air is blown into a flute. Symko and his students are developing much smaller devices that not only convert heat to sound, but then use the sound to generate electricity. The devices may be used to cool electronics, harness solar energy in a new way, and conserve energy by changing waste heat into electric power.ScienceDaily: A Sound Way To Turn Heat Into Electricity - Link.

HOW TO - Connecting a 3.3V device to a 5V microcontroller
Spark Fun has a simple breakdown of the various ways to interface 3.3V logic devices to 5V logic devices -
If you've ever tried to hook up a 3.3V sensor to a 5V micro, you know what I'm talking about - connecting these two can be a problem! There are several ways in which a 3.3V device can be safely connected to a 5v microcontroller. This tutorial will detail a few ways in which this can be accomplished.Spark Fun Electronics - Link.Below is an example of how NOT to connect a 3.3V device (like the SCP1000-D01 pressure sensor with SPI interface) to a 5V microcontroller (like a PIC or AVR running at 5V). Although you may experience normal operating conditions, the lifespan of your 3.3V device will be dramatically shortened.

HOW TO - Make a triple barrel PIC controlled spud gun
Bill Gurstelle, this one is for you, a triple barrel PIC controlled spud gun -
This project is definitely not small potatoes -- three barrels loaded with spuds and charged with propane! Two PIC microcontrollers handle the User Interface, Azimuth and Elevation Aiming and Fire Control functions. Aiming is controlled with a joystick. The Fire Control subsystem verifies a projectile is loaded in the selected barrel before injecting the controlled charge of fuel and that the barrel is armed before firing. It doesn't verify the operator's age, sobriety or aim -- that's your responsibility. The chips will fall where they may.Gadget Freak Case #103: The French Fryin' Legion's New Secret Weapon - 6/4/2007 - Design News - Link - video & instructions.
