3d printing, the new frontier of piracy?

We’ve all heard the countless arguments about piracy in digital media. However, it appears that 3d printing or other rapid prototyping systems are bringing legal issues to a more physical world. The story goes like this: [Thomas]  bought a 3d printer. He’s a big fan of warhammer figurines. He spends tons of time creating some custom warhammer figures, and uploads them to thingaverse. Games Workshop, the owners of Warhammer, unleashed the lawyers and had the items removed.
There are so many angles to this story, the mind boggles. If I were an artist, and someone else was uploading copies of my work, essentially stopping my revenue, it would suck. Then again, if I were lucky enough to have a fanatical fan base that spread the love for my product with excitement and zeal, I might want to encourage them. Neither of those thoughts however, cover the legal issue at the base here. We don’t have an answer for you. Sorry. You’ll probably be seeing this issue pop up more and more often in the fu…

A personal manufacturing Stack Exchange

Over on Stack Exchange, there’s a proposal for a new CNC/3D printer site. It’s a personal manufacturing stack exchange, and hopefully we’ll see some awesome discussion when it’s eventually created.
Stack Exchange is already well-known for hosting the most useful programming site as well as awesome sites/forums covering everything from LaTeX to grammar. The proposed Personal Manufacturing site is sure to provide a ton of advice and discussion covering the hardware, software, electronics, and toolchains of CNC routers, RepRaps and mills.
The personal manufacturing stack exchange hasn’t been created yet – a few more people still need to commit to use it. Once that’s done, though, we’re sure to see a lot of very helpful advice and discussion from the Stack Exchange community.
Kudos to [Michael] for sending this in.

Case Study: “How I Nearly Doubled My Salary as an Introvert”

Last year, an IWT reader named Andre emailed me, asking to write a guest post about overcoming his barriers as an introvert. He was originally going to write about his quest to manage being an introvert — which a lot of my readers would benefit from — but the initial drafts were too focused on himself. I passed.
In January, Andre signed up for my Find Your Dream Job course — a big challenge knowing that words like “networking” intimidated him. Hearing stories about people negotiating $30,000 raises is fun to read, but not very realistic for someone who has enough trouble walking into a room and introducing himself to others.
The results: In the last 6 months, Andrew doubled his salary to nearly six figures, and he dramatically improved his social skills. He’s an introvert who’s learned how to accept his social skills — but systematically improve them. And he has ruthlessly torn down his invisible scripts that held him back for so long.
I’ll let Andre tell you exactly how he did it. Take …

A hierarchy of business to business needs

If you're selling a product or service to a business--to a non-owner--consider this hierarchy, from primary needs on down:

Avoiding risk
Avoiding hassle
Gaining praise
Gaining power
Having fun
Making a profit

In most large organizations, nothing happens unless at least one of these needs are met, and in just about every organization big enough and profitable enough to buy from you, the order of needs starts with the first one and works its way down the list.
That means that a sales pitch that begins with how much money the organization will make is pretty unlikely to work. Instead, the amount of profit has to be tied in to one of the other more primary needs of the person sitting across the table from you (as well as the committee or boss she reports to).
B2B selling is just like regular sales, except the customer (who might not be the person you're meeting with) is spending someone else's money (and wants to please the boss).

Tear-Aid is watertight and airtight adhesive repair tape marketed for use in repairing outdoor products. I first found it when I was looking at options for repairing a tear in a self-inflating sleeping pad and read a recommendation of Tear-Aid from a former bouncy-castle operator. That real-world endorsement was enough to get me to try it and it has performed well for me.

I didn't want to experiment with a liquid patch because I couldn't be sure if the solvents would interfere with the composition of the sleeping pad, so this option was attractive. The instructions are clear and application was simple. After preppng the area with alcohol, I peeled the backing off and pressed the tape over the problem area. The tape is tough but flexible, and is transparent. It sticks very well and the sleeping pad now stays at pressure perfectly.

Tear-Aid Type A is for fabrics and Tear-Aid Type B is for Vinyl only. I have tried Type A, but not Type B. My local sporting goods store stocks the sma…

Reading RFID cards from afar easily

RFID hacking has been around for years, but so far all the builds to sniff data out of someone’s wallet have been too large, too small a range, or were much too complicated for a random Joe to build in his workshop. [Adam]‘s RFID sniffer gets around all those problems, and provides yet another reason to destroy all the RFID chips in your credit cards.
The project was inspired by this build that took a much larger RFID reader and turned it into a sniffer capable of covertly reading debit cards and passports from the safety of a backpack or briefcase. [Aaron]‘s build uses a smaller off-the-shelf RFID reader, but he’s still able to read RFID cards from about a foot away.
[Aaron]‘s build is very simple consisting of only an Arduino and SD card reader. [Aaron] is able to capture all the data from an RFID card, write that data to the SD card, and emulate a card using his RFID cloner.
What’s really impressive about the build is that [Aaron] says he’s not a programmer or electrical engineer. His…

How to Find Free and Cheap Ebooks

Where I live, decent public libraries with connections to the software service Overdrive allow surprisingly easy checkout of "library books" wirelessly to your Kindle. The Overdrive system provides libraries with both audiobook downloads and eBooks. I find, like most, that reading or listening to these books on a computer is untenable, but transferring audiobooks to my Sansa Clip player is as easy as pie.

For the (increasingly) large selection of books with Kindle versions, it's very easy to get free content to show up via Amazon's Whispernet. Nothing fiddly about it, no cables either. And for the earlier cool tool of "User Manual First", Kindles are a pretty good place to keep these PDF files. Either transfer via cable (easy) or use your Kindle's email address which allow your docs to show up via Whispernet.

Finally, if you sign up for Amazon Prime service, you not only get free shipping on your purchases, you also get access to the "Kindle Owner&#…
