One of my first builds for the MAKE blog was the mint tin fume extractor. I was hoping someone would make a version and post it on the web, and it finally happened. Thanks for the link Phil, and a big Thank You to Shawn for posting a video of your mint tin fume extractor.

Chad sends this on how John Sweeney survived the recent bad patch of weather in the Northeast by using his hybrid car to power many devices in his house.
During an ice storm last week Sweeney, of Harvard, Mass., powered his house by hooking it up to his Toyota Prius. The Prius, a hybrid vehicle, starts the gasoline-burning mode of its engine every 30 minutes to recharge the battery with an internal generator. In turn, Sweeney ran his refrigerator and freezer, wood stove fan, lights and television off the car's battery.
So if you have a hybrid, do you need a generator? People have talked about hydrogen fuel cell cars being used in a similar manner to power houses, but does it come in a full size version yet? How do you use your hybrid or electric car for uses other than getting groceries? Are you still waiting for your mass produced plug in hybrid electric vehicle? How about a street legal battery electric vehicle? What are you doing to release yourself and others from the carbon bonds of foreign oil?

Tristan and Libby, sharing their cheese-making knowledge (photo via Mikey).
I was lucky enough to get a lesson in cheesemaking from Tristan and Libby, authors of the Whittled Down blog. A gallon of milk and a few other ingredients makes a pound of cheese, and you can go from milk to mozzarella in a couple of days. Check out their cheese-making posts here, and learn much more at at their highly-recommended favorite cheesiest of sites: Fankhauser's Cheese Page.

This is a really nice passive multitouch input by Randall Jones. It was designed to be an inexpensive, and extremely expressive, musical interface. I really like the simplicity, and it only cost about $50 to build. [Thanks Dan]
Physical modeling synthesis has proven to be a successful method of synthesizing realistic sounds, but providing expressive controls for performance remains a major challenge. This thesis presents a new approach to playing physical models, based on multidimensional signals. Its focus is on the long-term research question, "How can we make a computer-mediated instrument with control intimacy equal to the most expressive acoustic instruments?"

This is for a Make: television project Tod Kurt and I built -- a Wii nunchuck / Arduino "flight recorder" (more about the project to come). We used Tod's Epilog laser cutter to cut out a rectangle from the top of a Pelican case, so that I could mount a serial LCD panel there.
This turned out much neater than my Dremel cut version. The best part is the thick bed of evil yellow smoke that curls forth when you open the lid. I'm pretty sure this smoke is good for you, so I inhaled of it deeply.

I spotted this on eBay, a 1962 chemistry set from SEARS.

And here's another from the 1950s, The Gilbert Experimental Lab. Love the packaging...

You know I like Tweetree, I gushed about it yesterday. The main thing I like is that it gives you a graphic view of things you link to from Twitter messages. So in addition to seeing a URL, you also see a visual image of the thing it points to. This is especially nice when pointing to a Flickr picture. But what about other photo storage systems? Will Tweetree have to implement special support for each of them? And what if I create a new app, how long will I wait for them to support it. Probably not very long now, because they're hungry, but what about when they're rich and famous? Maybe they'll think that supporting the big apps is all they have to do.

Cousteau and the undersea world. Cameron and Titanic. And now, Joe Reinhardt and Mike Fields and the depths of Lake Moraine in upstate New York. Every summer, Reinhardt and brother-in-law Fields tackle a new DIY project at the family's lakeside camp. In 2005, the pair built their own underwater ROV (remote observation vehicle) with two video cameras feeding live images to a shipboard laptop - all for about 100 bucks Making things is second nature for Reinhardt. 24, a computer tech in digital imaging. This time, he got to indulge his underwater fascination:"I always wanted to be a marine biologist," says Reinhardt. "I love the water, and ships, and watching Discovery Channel with the real ROVs exploring the Titanic." Reinhardt and Fields built their homebrew ROV's frame out of PVC pipe, and its transparent camera housing out of scrap quarter-inch-thick acrylic tube from the local plastics supply (milled to watertight tolerances on a friend's lathe). They joined the two with simple but strong carpenter's ratchet clamps, The B&W video camera was $29 from Harbor Freight, complete with infrared LEOs for night vision. power supply, and 80 feet of RJll cable.
They scored a Chinese color "Spy-Cam" for $1 on eBay (plus $35 shipping), and ran its video signal up the audio wire in the RJll cable. After an embarrassing misfire with ballast tanks ("We put 'em on top, so it sank upside down every time"), the explorers improvised a solution ("a big hunk of concrete and a bungee cord") and lowered their ROV to the lake bottom to capture video of sunfish, perch, and muskie sporting in the wild. The rig proved watertight to 40 feet. This summer, they're going deeper: their 2006 model has thrusters for true independent ROV mobility, using watertight 12VDC motors coupled to propellers by super-powerful neodymium magnets. It'll be rated to 200 feel, good enough to dive quarries or wrecks on Lake Erie, Reinhardt says, James Cameron might want to check his rearview mirror.

Annalee @ io9 pointed me towards a story we'll likely hear again and again until authorities realize that we're never going to encourage the next generation of chemists if we treat every kid with a home chem lab like a criminal... As Annalee said to me in email... "We should be championing this cool kid who created an awesome home lab" - Crimes Of The Future: Teen with Home Chemistry Lab Arrested for Meth, Bombs...
A Canadian college student majoring in chemistry built himself a home lab - and discovered that trying to do science in your own home quickly leads to accusations of drug-making and terrorism.
Lewis Casey, an 18-year-old in Saskatchewan, had built a small chemistry lab in his family's garage near the university where he studies. Then two weeks ago, police arrived at his home with a search warrant and based on a quick survey of his lab determined that it was a meth lab. They pulled Casey out of the shower to interrogate him, and then arrested him.
A few days later, police admitted that Casey's chemistry lab wasn't a meth lab - but they kept him in jail, claiming that he had some of the materials necessary to produce explosives. Friends and neighbors wrote dozens of letters to the court, testifying that Casey was innocent and merely a student who is really enthusiastic about chemistry.

Brad sends this about his son's gift project:
For Christmas this year, Lucas made his grandmom a battery powered amp for her guitar. This was a big project - first time with a soldering iron. Worked out well with only one minor burn. He did 80% of the soldering and drilled all the holes for the pots and LED. He turns 6 in Jan - seemed he should learn one last skill while he was still 5.
Great project! Parts to love: scrounging parts out of otherwise dead or useless devices...teaching new skills to kids...making something that couldn't be bought...online documentation...photos...
What have you made lately? Did it work right the first time? Did you catch some pictures/video/audio of the process? What is your experience teaching kids about electricity, electronics, soldering, programming, hacking? What should people do or not do when they venture out into projects with kids? What workspace, tools or materials would you suggest? Show us your stuff! Add your comments and park your photos and video in the Make Flickr pool.
