MAKE subscriber WidgetNinja writes in to share their first circuit board design, a fan speed controller. This circuit monitors air temperature in a home theater equipment cabinet, and regulates the speed of a fan in order to keep the whole thing cool.
Rather than using a microcontroller and some custom code, this controller is based around the TC649 fan controller from Microchip. A neat feature that this chip incorporates is a fault detection circuit, that will trigger if the fan motor stops working. It's probably overkill for most projects, however it could come in handy if you are using the fan to protect expensive equipment from being damaged.
Congratulations on your first build, it looks great!

Decoding Jackson Pollock @ Smithsonian Magazine via jk.
Did the Abstract Expressionist hide his name amid the swirls and torrents of a legendary 1943 mural? An art historian makes the case for a signature gesture... Pollock's possibly writing his name in Mural testifies to an overlooked feature of his works: they have a structure, contrary to the popular notion that they could be done by any 5-year-old with a knack for splatters. In my view, Pollock organized the painting around his name according to a compositional system-vertical markings that serve as the loci of rhythmic spirals-borrowed directly from his mentor, Benton.See if you can spot it!

The other night at Maker Faire Rhode Island, I met up with Raphael. He had brought along these neat prototyping kits made from cigar boxes. I asked him about why he made them and what he does with these mobile prototyping platforms.
You may also want to check out Raphael's Twitchie kit, which people were passing around like mutant babies. Very disturbing indeed.
In the Maker Shed:

It's a cause for celebration every time a feed is cloud-enabled, but it's a special victory when a large tech news site takes the leap. The first to do so was GigaOm, which became a source of realtime updates on the same day that WordPress got the feature. Now the second big brick falls into place -- TechCrunch.

This clever video pieces together scenes depicting the already-hoary suspense-film cliche in which a cellular phone's signal (or battery) gives out at just the wrong (right) time so that the characters will have something to be in suspense about. One thing I will always and forever love Iain Banks for is his 2003 novel Dead Air, a gripping, taut suspense novel in which everyone has a cellphone that always works. I was struck when I read it, believing that Banks had just created an entirely new genre: suspense novels in which none of the tension comes from characters not knowing key facts.
Sam sez, "An open letter to Lily Allen, explaining the facts around filesharing, sung to the beat of one of her tunes."
I love this -- it's a great mix of compassion, artist's manifesto, and humor. I don't know much about this Dan Bull character, but I like the cut of his jib.
Dan Bull - Dear Lily (Thanks, Sam!)

Instructables user BobS made a gyroscopic image stabilizer from two harddrives and some spare parts. I'll save this one for my next helicopter trip over the Serengeti.

Take subscription services for example. Sure, I'd love a service that would allow me to download unlimited content in high bitrate MP3 format for a reasonable fee every month. Except economics and greed will never let that happen.Notice what he says here. The DRM isn't what enabled the business model. It's fear of how people will use such a service that does. It's fear that people will actually use what's been given to them -- leading to the claim of "economics and greed" stopping such a service from ever coming about. But, that makes no sense. People already have access to pretty much every song ever recorded with no DRM at all. Claiming that they need DRM to enable such a service makes no sense. It's already there -- just not legally. So what does the DRM stop in such a service? Absolutely nothing. If the fear is that someone takes a song and shares it online... too late. It's already happened. The only thing that DRM does in that situation is put up a restriction on a legitimate, paying customer. That makes no economic sense at all.

This weekend, a crew of MAKE folks (myself included) will be at the Handcar Regatta, right here in Sonoma County. We're excited because it's not everyday that there's a maker event in our own backyard. If you're not familiar with it, the Great West End & Railroad Square Handcar Regatta & Exposition of Mechanical & Artistic Wonders is centered on hand-built railcar races, complete with awesome rules like "Racers and builders are one. Those who would ascend a contraption upon the rails to compete shall too be the builders of said vehicle." The vehicles must be human-powered and teams are judged on more than just speed: "Ostentation, bewilderment, whimsy, beauty, ridiculousness, and capturing the fancy of a seven-year-old girl are all reasons to build calamitous contraptions upon the rails."
Today, I visited one of the teams in their workshop behind a little white house in Santa Rosa, home of Whiskeydrunk Cycles. The Thennagin Bomber crew were up to their elbows in grease, parts, and whiskey, and the Bomber is looking mighty fine. Pictured above is the core team (from left to right): Klaus Rappensperger, Joshua Thwaites, Neil Espenship, and Joey "B.A.M." Castor, in front of the Tandemonium, their build for last year's Regatta. A little healthy rivalry is fueling the Thennagin Bomber build, as the gentlemen recalled their reaction to seeing the Hennepin Crawler's transformation from railcar to street car last year. They were inspired by the Crawler and built the Bomber as the "upgraded, faster homage." The Bomber is also a nod to bootleggers of old, running illegal whiskey. Incidentally, the Bomber boys mentioned that their nickname for the Crawler is "Crank, Rattle, and Hum."
As for what's "under the hood" of the Bomber, the crew took apart the motor from Klaus' Honda XR100 and pulled the transmission only, so they could have four gears to play with. They also turned it backwards to keep the gearing sizes low:

They used the front axle from a 1917 Ford Model T, turned upside down to fit the camber of the wheels, which are 19" spoke wheels from a 1929 Ford Model A, outer flanges cut off. The Bomber has a second set of rims with tires for street runs. Basically, they were going for a Model T that's pedal-powered. Hot!!

The steering box is pulled from a Toyota Corolla and they employed a boat crossover steering system for the cables:
One of my favorite features is that they branded by incorporating metal whiskey bottle silhouettes throughout:

The Thennagin Bomber crew said they'd be sure to mount the gift that was dropped off for them from the Hennepin Crawler team:

When I asked them if they were going to win this year's Regatta, Joey piped in: "We already won." The joy is in the build, not the win. Well done, gentlemen!
The Thennagin Bomber crew thanks everyone who helped them along the way, in particular their Hype Man Buzz for providing liquid courage and mota-vation and of course the ridiculously adorable Whiskeydrunk Cycles shop dog Eleanor.

You can see more pics of the Bomber build in action on their Facebook page. See you at the Regatta!

A brief report on where we're at with rssCloudLand as September winds down.
The venture also threatens traditional news media in the Bay Area, because it will rely on 120 journalism students at Cal who will work for free. The massive free-labor workforce will give the new venture a huge advantage over established Bay Area media organizations that depend on paid, veteran journalists to gather and put together news stories.I read that and all I can think is, Mr. Gammon, did you really just mean to suggest that your years of experience and professional connections are so worthless that a group of students will automatically beat you in the marketplace? Because that's what he said. After we keep being told how pro journalists are so important, and all their experience, knowledge and reporting chops differentiates them from the unwashed masses, here is a guy who is flat-out admitting that he has no advantage over some pure amateurs.
Let's hope UC Berkeley and KQED seriously rethink this plan before it goes live early next year. The idea of a non-profit news organization has merit, but using what amounts to slave labor to make it happen is bad for journalism.So, let me see if I get this straight. Things have been really bad because there were fewer reporters working on the news, and we'll all miss them when they're gone... but as soon as anyone new enters the market, it will be bad for journalism? And even if the journalism is done by students who have no experience, the amazing pros simply won't be able to compete? Yeah, that's believable.





By way of the Steampunk Workshop comes this awesome classic horror-themed MAME cabinet by Doug Haffner. Doug is a fan of steampunk, Harper Goff (designer of Disney's Nautilus for 20,000 Leagues) and Kenneth Strickfaden (set designer and prop builder for Boris Karloff's Frankenstein). He decided to combine his love for all three in a MAME (Multiple Arcade Machine Emulator) cabinet and home jukebox.
The work here is impressive, but especially cool are the Lithopane portholes on the sides, grayscale images of the Frankenstein monster and his bride CNC-carved into Corian plastic (used in counter tops). Once carved and back-lit, you get this cool glowing halftone effect.

FNB: It's true, everyone is talking about this, what is the economic model? Is there one?Indeed. We've been pointing out for the better part of a decade that going to the movies is a social experience, and the best way to do that is to make that experience better. Many theaters have started to catch on to this (finally).
SP: Not yet. The music industry is slightly ahead of us and had to go through the same thing already and it's shock, horror, terror, everyone's going to go bankrupt because everyone can have everything for free. Lots of resistance, I'm talking about filmmaking now, legislating against copyright and everything is watermarked, anxious, anxious, and all that. And I think my attitude is, go the other way. Open the gates, say "okay have it." It's free, it's yours and then if you want me to go on and make other things, you're going to have to complete the circle by going out and buying the DVD. Maybe in the future it will be some sort of subscription model but I always wanted to do that with this one.
FNB: There was a recent article we read that said the next generation of digital consumers still wants to pay to go to theaters. It's not mutually exclusive, which is calming to know that just because one is succeeding doesn't mean the other is going to disappear.
SP: Its not either/or, it's AND. It might make cinema owners and distributors sit up a little bit, and make it a more pleasant and thrilling experience to go to the theater, make the quality of the projection better, the seats more comfortable, make it back to the real beginnings of what joining together in a big group is all about. Similar people can have their own access to watch it home on Blu-ray, its one of the things that I do. I have a good screen and I watch things together with a group of friends. Comfortably lying about. And that feel just as true of a cinema experience as going to some wonderful cinema.
A billion trillion, also known as a "sextillion," could be written as a 1 followed by 21 zeros. I know the dollar has weakened lately, but a sextillion dollars would still be a lot of money. The gross domestic product of the entire world in 2008 was only $60 trillion, so even if Chiscolm won it might be a little hard to collect.Bank of America Sued for 1.784 Sextillion Dollars"These are the kind of numbers you deal with only on a cosmic scale," said Sylvain Cappell, who is New York University's Silver Professor at the Courant Institute for Mathematical Sciences, and so presumably can count really high. "If [Chiscolm] thinks Bank of America has branches on every planet in the cosmos, then it might start to make some sense."
