How-to Tuesday: 1934 USB web cam

Tuesday, November 18th, 2008

IMG_5563w.JPG
A while ago I converted a 1934 folding camera into a USB web cam. I brought it with me to Maker Faire Austin 2008 and a lot of people seemed to like it. In fact, a lot of people wanted to know how I made one. I promised them I would do a how-to on the blog, and I always keep my promises, so let’s get started.

The best part about this project is the availability of the cameras. I was able to pick up a USB web cam for $10 at a local bigbox store. The antique cameras I picked up on ebay for $1. Actually, I picked up (2) cameras for $1 each and the shipping was only $5. That was a great deal. You can easily pick one up for less than $10 online or a local antiques shop.

What you need:

  • Antique folding camera - Available on ebay for $1 - $10
  • USB web camera - Available for $10 - $20
  • Heat-shrink tubing
  • Rosin core solder

Tools you need:

  • Soldering Iron
  • Glue Gun
  • Arms of Assistance - Make you own
  • Fume extractor - Make your own
  • Miscellaneous hand tools - screw driver, needle-nose pliers

Step 1: Purchase the cameras

First you need the cameras. Scour the Internet, check local antique shops, or ask your friends. These types of cameras, both the antique camera and web cam, are readily available and they are very affordable.

Step 2: Remove the lens

Start by opening up the antique folding camera. There is usually a switch somewhere that slides over so you can load the film.

Google SketchUp 7 is here!

Monday, November 17th, 2008

Adrian from Google has an overview of the latest SketchUp, he writes -

We’re very excited to announce the new release of Google SketchUp 7. If you don’t already know about the fun you can have with SketchUp, here’s a quick recap:

SketchUp is software you can use to build 3D models of anything: your house, killer robots, furniture, trees, abstract art — anything. Architects and engineers use it to design buildings and other structures. Woodworkers use it to plan their projects. And lots of people use it to figure out where to put their furniture. SketchUp is easy to learn, it comes in free and Pro versions, and it’s more fun than a houseful of clowns. Oh, and you can use it to build models for Google Earth, too.

So what’s new in SketchUp 7? There’s too much to list here, but we focused on three major areas for this release:

Making it even easier to get started – We’ve created a new class of “smart” objects called Dynamic Components, which are simpler to work with for new modelers. Take a look at this video to see what I mean:

Making it easier to share what you make and collaborate with other people – We built a better link between SketchUp and the rest of the 3D world, made it possible to “sign″ your models, and added Google Docs–style collaboration and sharing to our 3D Warehouse.

Adding powerful features for experienced SketchUp Pro users – SketchUp is only half of the SketchUp Pro suite; the other half is all about sharing your work with your clients. LayOut 2 (which is now officially out of beta and rarin’ to go) lets you create multi-page documents and presentations. Your models are linked to your LayOut file so that changing the former automatically updates the latter.

Take a look at the What’s New in 7 page on the SketchUp website to get the whole scoop. There’s a great video to watch, and it stars some of the more prone-to-sunlight members of our engineering team — in lab coats, no less. Don’t miss it.

There’s a detailed list at their “What’s new” page too - it looks like a great update!

Industry gives a laboratory to America’s young scientists… WE CAN DO IT AGAIN?

Monday, November 17th, 2008

Make Pt1265
Industry gives a laboratory to America’s young scientists… Popular Science 1941.

YOUTHFUL, IMAGINATION, an inexhaustible national resource, is being developed along scientific lines by the American Institute of the City of New-York. This organization, chartered in 1828 and devoted throughout its existence to the promulgation of science and the encouragement of American industry, established its junior branch in 1928 and recently has intensified its efforts in this direction through the American Institute Laboratory at 310 Fifth Avenue, New York.

Its aim is to direct and utilize the imaginative faculties of youth which, since the founding of the institute, have been turning more and more toward science and mechanics. Under its wing are more than 730 juvenile science clubs, scattered throughout the United States, its possessions, and foreign countries. Some meet in high schools, some in settlement houses, and some are spontaneous youthful organizations with cellar or attic laboratories and club rooms. In the aggregate there are more than 30,000 youthful club members.

They experiment with model airplanes, bacteria, telescopes, radio, tropical fish, light, sound, animal-breeding, and in numerous other fields. Their ambition is limited only by their own knowledge and the cost of equipment, and it was to obviate the latter difficulty to some degree that the American Institute Laboratory has been established with the cooperation of the International Business Machines Corporation, which gave the use of two floors of a New York City office building, and of the Westinghouse Electric & Manufacturing Company, which supplied the equipment.

This is (was) pretty cool, maybe we as in makers, society and a science hungry public can bring this back!

Here are the companies listed in the article…

“American Institute Laboratory” I can’t seem to find if it exists as it once did, anyone know? All the references on Google are from books from the early 1900′s - they coordinated science fairs at the time it seems. Science fairs go back to at least as far as 1928 when the American Institute of New York City first held one for city youth at the Museum of Natural History. In 1950, science fairs went under the auspices of Science Service, a non-profit organization. It became international in 1960.

International Business Machines Corporation (IBM). IBM is still around and they continue to support science for kids. IBM gave 2 floors in NYC, I wonder if they′d be willing to do this again? I’ve email our team who has worked with IBM before on the IBM IGNITE camp.

Westinghouse Electric & Manufacturing Company. Westinghouse was founded in 1886, then it bought CBS in the 1995 and renamed itself the CBS corporation, in 1998 CBS creates a subsidiary called Westinghouse Electric Corporation. In 1999 CBS sells the nuclear assets to BNFL that operates as Westinghouse Electric Company, the business in then sold to Toshiba. CBS is then acquired by Viacom, Viacom calls itself CBS corporation and CBS retains ownership of Westinghouse Electric Company. Companies have licensed the Westinghouse name but they’re not sold by the original company.

So… It seems to me CBS or Toshiba might be the ones to ask about sponsoring this again? Anyone work at either place, email me.

We have a chemistry book (below) - I’d like to see that get out there to more folks and perhaps develop a “new” chemistry set for kids to go along with it. Imagine 2 floors of science learning in each major city, doing real chemistry experiments!

9780596514921-2-2

Jumping the gun, pulling a fresh shot of espresso

Sunday, November 16th, 2008

I′m pretty predictable. I couldn’t wait 2-3 days to try the new batch of coffee I roasted yesterday. These are some photos of me making a shot of espresso. It was a bit overroasted, yet grassy at the same time! This points to my temperature being a bit high and my guess is the grassy taste will mellow out in a few days. It’s still quite good, and very satisfying to have made from scratch. If only I could grow a few coffee trees in our back yard…

Game of Life kit is suitable for framing…

Sunday, November 16th, 2008

Funnypolynomial framed up the Game of Life kit, nice! via Ladyada.

I’ve been fascinated by Life since I first read of it in Scientific American, many years ago (October 1970!). The Maker Shed store had a couple of sales so I bought a total of 6 Game of Life boards. I assembled them as a 2ҳ panel and used cables to join the edges. I mounted them in a simple frame. I’m moving back to New Zealand soon, this will be my last project in the Bay Area!

Backyard coffee roasting

Saturday, November 15th, 2008

My supply of decent roasted coffee is at dangerously low levels, so my daughter and I spent a short time roasting coffee today. There are some great books and online resources for coffee roasting, but in a nutshell, here’s my simple method (purists will cringe; you can be much more precise about all of this. I overroasted mine a bit today):
I used a hand-cranked stovetop popcorn popper, a stove (I roast on the side burner of my gas grill to keep the smoke out of the house), a high-temperature thermometer (such as the thermocouple on a multimeter), green coffee beans, and a colander.

  1. Heat the popper to around 400° Fahrenheit.
  2. Pour in the green coffee beans, close the lid.
  3. Slowly crank the handle for around six minutes, listening for “first crack″.
  4. Keep cranking while you wait 2-3 more minutes, then open the lid, blow off some smoke and check the color of the beans. When they approach the roast color (not black!) you desire, kill the heat.
  5. Dump the beans into the colander and start shaking and stirring them to cool and let the chaff fly off. Once cooled, put them in an airtight container, or even better, a container with a one-way valve to allow degassing of CO2.

That’s it. If you′re roasting beans for drip, French Press, or vacuum pot enjoy your newly roasted coffee right away. If you′re making an espresso blend, wait an agonizing two or three days for the CO2 levels to drop, otherwise you′ll have some fairly fizzy crema to contend with.

It makes pretty good economical sense if you exclude the cost of your own labor (this qualifies for a hobby “exemption” in my mind!). I compare $4.80/lb. green beans favorably against $15/lb. roasted beans.

It’s also an eminently hackable pursuit. Popular non-commercial methods include converted air-poppers, the heatgun/dogbowl combo, and grill rotisseries.

Maker’s Notebook light mod build photos

Friday, November 14th, 2008

I took my first stab at sewing the conductive thread from the Lilypad e-sewing kit into my Maker’s Notebook bookmark ribbon. I have gotten some great suggestions from readers on switches and wires and things, which I have yet to try. Currently, I’m just putting the coin battery into the battery holder to test out my sewing job. It works pretty well, and puts out enough light to scribble ideas late at night without disturbing anyone who’s sleeping. What’s this “sleep″ they speak of, anyway?

Quantum of Solace - The Do-it-yourself version, more gadgets!

Friday, November 14th, 2008

Qos-Wallpaper-1-Lg
I saw the latest James Bond movie Quantum of Solace - besides some cool 3D phone imaging and some touch screen action there wasn’t a lot in terms of gadgety spy gear. There was a hydrogen powered hotel but in the end that didn’t really work out. So, if you’re like most makers you probably like(d) 007 movies for crazy spy gadgets which eventually either became really or something you could make now. I still think “Q” had the coolest job in the world, he would outfit our hero with the latest gear for getting a spy job done: booby-trapped briefcases, walkie-talkie in a broom, bug decoders, tape recorder cameras, dagger shows, garrote watches, modded cars, homing beacons, underwater jet packs, x-ray desks, fake finger prints, mini-subs, the list goes on and on

Here are some DIY versions (or close to) of what I saw in the movie… something for kids and adults out there who want to do this on their own :)

Remote jaw mask development

Thursday, November 13th, 2008

A magician friend of mine occasionally asks me to build tricks for him. I’m flattered and find this to be incredibly cool, especially after Michael Caine’s portrayal of the magician’s engineer (pronounced all French and awesome) in the movie The Prestige.

This time he wants a remote controlled ventriloquist’s jaw mask to deploy on unlucky volunteers from the audience. It’ll be the lower half of a face mask with a hinged jaw that flaps up and down. In the routine the “ventriloquist” will be offstage talking through a microphone and flapping the jaw on the “dummy” audience member via remote control.

This is my rough model of an approach I was thinking of testing. I’ll stick small servomotors at the hinges, run a battery and receiver around back (maybe a belt pack?) and use an R/C remote. We’ll probably make the mask out of very lightweight plastic, like a kid’s Halloween mask, so that the jaw can flap quickly. What other approaches can you think of?
