Basically this is a 3600 sqft space. But 1400 sq ft amounts to a warehouse space. That 1400 sqft GAMA-GO would be interested in if the tenant didn't want it.
The rest of it is this large, hardwood floored open space with a huge multi-faceted window and street entrance/storefront.?
It's a nicer, larger space than our office/store area and would make for an AWESOME shop or office + shop or workspace + store, or any number of things.
The real kicker is the price. The landlord is offering it at *well* under market value
I quite literally had this proposed to me this morning and have been scratching my head about it all day. I can't tell you how much I'd love to have something like a homebrew 3D printing club or a do-it-yourself maker store with workshops next to us. Something fun, ya know?
Anyway, if you know of anyone that might be a good fit, hit me up and I'll give them the scoop. It's World Space Week!
Did you know it's World Space Week this week (55 nations, the largest public space event on Earth)? Me neither. School kids and adults from all over the world are learning about space and celebrating our humble little parking spot in the Milky Way. Check out the World Space Week website for participating organizations, a calendar of events, materials for teachers and students, etc.
Add the SunMod kit to your remote control and you will never need to replace the batteries again! Just turn your remote over, place in the sun, and let the charging begin. Hack any AA or AAA powered device to make it solar powered. Please Note: Rechargeable NiMH batteries are required, and not included.

The NYC Resistor cats continue to work on their "Fear & Loathing in Las Vegas" slot machine slash barbot that tweets! The rival hackerspaces will need all their nerdgenuity to top it. Apparently, Pumping Station: One is building a bicycle-powered ice-cream maker that makes glow-in-the-dark desserts? Oh yeah!

The Iterated Function System, or IFS, is one of the simplest techniques for creating natural-looking fractals. The IFS consists of a handful of transformations (more on these in a second) that describe how to change one point into another. The Barnsley Fern, which looks like a Black Spleenwort (a kind of fern), is the classic example of an IFS fractal, but there are many varieties. Larry Riddle has a nice breakdown of others on his IFS systems page.
The technique works like this. Starting from a single point, usually (0,0), you randomly apply one of the transformations that make up the IFS system. Then, once you have the new, transformed point, you plot it on the screen, which in Processing, we do with the set() command. Then, you repeat the process again starting from the point you just computed.
After a few hundred iterations, you'll begin to see a ghostly outline of a fern. After 100,000 iterations, you'll see a detailed image that looks almost exactly like a natural object. The following image shows the IFS system for the Barnsley fern, as well as the image that results when you apply the process over and over.

New in the Maker Shed: DrinkShield for Arduino
The DrinkShield is an open source Breathalyzer kit for the Arduino. It's a great starter kit that was originally designed for Hackerspace parties. The DrinkShield can work as a standalone breathalyzer or you can connect it to a computer for and interact directly with the results. Source code repository comes with a game to use as a proof-of-concept.

Codebox: Create a fractal menagerie A fractal, according to Wikipedia, is a "rough or fragmented geometric shape that can be split into parts,[link widoczny dla zalogowanych], each of which is (at least approximately) a reduced-size copy of the whole." One of the cool things about fractals is that they use really simple processes to create really complex, natural looking objects, like plants, clouds, flames, and so forth. This Codebox will show you how to create a fractal menagerie for viewing a few different styles of fractals, like this:

IR detectors are little microchips with a photocell that are tuned to listen to infrared light. They are almost always used for remote control detection - every TV and DVD player has one of these in the front to listen for the IR signal from the clicker. Inside the remote control is a matching IR LED, which emits IR pulses to tell the TV to turn on, off or change channels. IR light is not visible to the human eye, which means it takes a little more work to test a setup.

Since this made cutting so much quicker, I was also more willing to cut multiple chambers inside the book. Use this method to build a hiding place for your electronics, jewelry, and secret plans for the midnight raid on the cookie jar. It could also be used to make a unique project box for one of your electronics builds.
Longreach is a man-portable system that allows for the rapid conveyance of temporary, water-activated buoyancy devices to a drowning victim's location. It is designed to allow a victim to remain buoyant while rescue personnel prepare the appropriate response to the situation. The rescue package uses hydrophobic or rapidly expanding foam to provide buoyancy once the package contacts the water. This allows the package to be vastly smaller in size than any currently existing buoyancy device. Equipped with a light for attracting attention the Rescue Package can be propelled over 150m. Longreach is also equipped with Para-Flares for night-time Illumination. Longreach is designed to be simple to manufacture and easy to handle. Ideally used by emergency services personnel or a ship's crew, Longreach has the potential to significantly reduce the number of drownings at sea. Whirlpool fountain

UNSW Industrial Design student Sam Adeloju's Longreach Water Rescue System won this year's James Dyson Award, surpassing the Minotaur Fire Nozzle System, Copenhagen Wheel, and Move-it cardboard hand cart for the ?20,000 prize (~$32,000 split equally between the maker and their University.). [via /.]
There are a few difference between these and say a CdS Photocells:

IR detectors are specially filtered for Infrared light, they are not good at detecting visible light. On the other hand, photocells are good at detecting yellow/green visible light, not good at IR light
IR detectors have a demodulator inside that looks for modulated IR at 38 KHz. Just shining an IR LED wont be detected, it has to be PWM blinking at 38KHz. Photocells do not have any sort of demodulator and can detect any frequency (including DC) within the response speed of the photocell (which is about 1KHz)
IR detectors are digital out - either they detect 38KHz IR signal and output low (0V) or they do not detect any and output high (5V). Photocells act like resistors, the resistance changes depending on how much light they are exposed to

In this tutorial we will show how to

Test your IR sensor to make sure its working
Read raw IR codes into a microcontroller
Create a camera intervalometer
Listen for 'commands' from a remote control on your microcontroller

The event launched on Monday, Oct 4, the 53rd anniversary of the launch of Sputnik. [Thanks, Rachel!]

Why hot sauce cleans pennies
Ideal and cheap San Francisco location for a hacker space My friend Greg Long of the wonderful Gama-Go emporium of cool products is looking for people who are interested in starting a hacker space in a building that Gama-Go might move into.

Along the way, we'll continue to expand on the object-oriented programming (OOP) concepts introduced in Chapter 9 of Getting Started with Processing, as well as show how to use the great controlP5 library to create familiar GUI controls used in other languages.

10.10.10 Hack-A-Thon!
I love hollowed out books. They make excellent hiding places or they can be used as unique and tricky double gift wrap. "Ah-ha, it's a book wrapped up in a book!" I've built hollowed-out books before, using the time-honored, frustrating, and very time-consuming hobby-knife method. This time, I decided to speed things up (by hours!) using my Dremel Multi-Max oscillating tool.

How: Register (for free). Event runs from 7a Saturday to 7a Sunday PST. Weird timing, I know, but it's (inter)national!

Where: The Seattle event is being hosted by Jigsaw. Associating with Jigsaw and attending at Jigsaw are mutually exclusive and are not required. (ex: you can mark Jigsaw as your space, but not attend physically; you can attend at Jigsaw but mark another space as your connection; you can hang out with us while we code and not do anything; etc) Check out eventbrite to find out if your local space is participating. Not listed? Want to put one together? Register, and someone from the Tropo sponsor will reach out to you about providing food and such!

BTW: You may recall that ugliness over the whole "Geeks Without Borders" naming conflict. It's been resolved. "GWOBorg" now stands for "Geeks Without Bounds." Problem solved. Yay.

This room was constructed with the humor of Rube Goldberg cartoons in mind at the St. Louis City Museum. Developed organically, the room started with one exercycle on the bench and the thought, "What can this become?" From there, visual and comedic mechanics were added day by day to create a space that with the push of a button, the room would erupt with motion and activity. A line shaft and belt system from the Industrial Revolution was used to transmit power and action over the viewers head, encompassing them with movement and the challenge of deciphering what powers what. An umbrella opens and closes with the aid of cables and manikin hands, a cup floats and falls with the power of pneumatic pistons, a 3ft. wheel of feet kicks up opposing balancing beams, a leg and foot continue to 'kick the bucket' and a fireplace bellows that spins the pinwheel. The line shaft continues on the opposing side to spin a turn of the century shoe polisher and a wall of interconnected bicycle wheels. Shovels hang from the ceiling while being punched by boxing gloves and old dry cleaner racks play the xylophones.
In an age of digital automation this purely mechanical machine was created by trial and error, with the driving thought "Maybe this will work."

I was thoroughly entertained by this bit of hobby chemical sleuthing from Michael August Pusateri, who observed years ago, while bored on-shift, that the hot sauce at the fast food joint where he was working would clean the oxide off a penny. My immediate assumption--that the effect is due to vinegar or some other acid in the sauce--turns out to be only half right. The right answer, and the process by which Michael arrived at and verified it, make for interesting reading. You might even find a use for it.

AnnMarie Thomas (whose work has appeared in MAKE Magazine as well as Make: Online in the past, links below) created this adorable LED costume for her daughter. If you can't figure out how to make it by looking at the pic, she created an Instructable to guide you. (I love the anode/cathode leggings!)
This "reverse fountain" is called Charybdis, as in to be caught between Scylla and. Briton William Pye designed it for Seaham Hall, in Sunderland, England, using a massive acrylic cylinder to give the appearance of a containerless volume of water.

Not sure you could make one that fit an adult this way, but nonetheless a very cool bit of trash-hacking from Filth Wizardry. [via CRAFT]

The amazing Technicolor LED fur coat

This isn't the first LED fur coat we have seen, but it may be the first one made entirely from scratch? The maker, DustMonkey, couldn't find a coat that met all his criteria, so he started with McCall's pattern #4222. After making the coat, he attached 256 RGB LEDs, an Arduino, and custom LED controller to light everything up.
