D3CRYPT3D won SXSW Interactive Innovation Award for Privacy & Security

Hey everyone! For a long time, being a modeler and working in the industry, I have always felt that Modelers get the short end of the stick.  Things get re textured, models get hijacked and studios just kind of store models and stock pile them up. Some people will even resell models that don't belong to them. I used to see it all the time. Well, my crew and I came out with a software that enables you to share and collaborate on your 3D files securely. We won the SXSW Innovation Award for Privacy & Security last month and just released our beta this week.  We would love for you all to try it out and give us your feedback so that we can make the best product possible.  If you are interested, here is the link to download -   www.d3crypt3d.net/downloadnow/ Thank you!

Why won't instructables.com remember that I'm logged in? Answered

No matter where I log in, whether it's on the top of the page, on the dedicated login page, or on the pop-up box when I click "View all on one page", I always have to log back in when viewing a new instructable.  This happens at work, using IE7, and at home, using FF3.6. And yes, I'm checking the "keep me logged in" box.

How do I add entry detection, and possibly concealed video capture, to my office door?

I suspect someone is pilfering through my things at work, when I leave my office to walk across the lobby to the restroom. I need to be alerted if this is happening, and, even better, get a video capture of the person doing it that may be burned to disk as proof, and reprimand!

Hello, Could anyone tell me what type of security tag this is? I have Googled and Wickipediad en.wikipedia.org/wiki/Security_tag  around the subject looking for,  'induction coil security tag',  but I mainly find information about the flat strip type. I'm new to electrickery so I am guessing it is an induction type of device? Also, is the green component a capacitor? ...um...  Thank you.

How do I bypass a card-reader type security system?

I'm trying to find a way to bypass the security system in my building, a simple card-reader setup. Really more a prank than not.  My boss has been watching my card and logging the times it's accessed, I want to show him that he can't trust the card.  Nothing nefarious, just proof that I can be around and not have to access my card.  If it helps, the security company is Datawatch.

DIY Motion activated security camera

Ok i like the idea of where you put a security camera in a hidden spot around the house to capture those unwanted trespassers, but recording unwanted recorded video from the the night you were on vacation sometimes is a pain to watch since you have to watch the whole thing or fast forward to the part where someone came "unnoticed" (especially when you have some people in the neighborhood egging your house). anyone have an idea where a standard security camera (mini cameras, cctv, wireless w/ IR lighting) can be hooked up to a computer (or better a stand alone hard drive) and able to use a motion detector and also only record video that shows "someone" on the property when activated?

How to create reed switch that activates wireless alarm?

I've been reading alot about reed switches after learning about a security feature for cars, a reed kill switch. I wanted to know how to or if someone could create some kind of setup where if the reed switch closes the circuit, it will activate a wireless remote or something like an alarm within a reasonable distance from the actual switch. I've seen those window/door entry alarms. Would those work? For a car, would it be possible to have the reed switch activate a small alarm in a key fob type of thing?

Any tips on disassembling bullet camera and relocating the lens module?

Hello!  I've been reading instructables for a while and now it's time to join and post a question. I've been finding nails in my driveway and want to catch who's doing this.  I've got a 4 channel security camera on it's way and have been thinking and researching ways to hide them.  Due to the 'clean' surfaces around my home, it's going to be tough to make the 2" diameter x 6" long bullet cameras blend in (so people don't vandalize/steal them).  I've spent hours searching how to camouflage cameras, so I know the 'typical' tricks. I'm thinking about making a fake gutter extension and hiding the camera in there (so it blends into my one story house), possible installing a gable vent on my garage and pointing a camera through that, or trying to mount a camera about 20' up a nearby tree.  My favorite idea is to take apart a bullet camera and move the camera lens module, which is much smaller than the whole camera housing, to a more discreet location. I've searched for a while but can't find anyone who has done this with an IP66 outdoor style camera.  I know I'm going to lose the IR LED's around the lens, and that's ok (I'll have 3 other cameras for night vision).  I think I can point the camera through a small knot hole in my privacy fence and be able to detect who has last walked by when the nails appear.  I might make a small weather proof enclosure to protect the lens module...I think I'm a good tinker-er so this isn't the problem. Has anyone hacked apart a security camera and moved the lens module (by extending the wires) to a remote location?  I know there are small cameras for sale, I know I can hide a camera in a bird house, etc...but I like to make things.  I'm just looking for advice/tips from someone who has done this.  When I search for 'hack apart a security camera' I get a bunch of 'hacking into a security system', or 'spy on your neighbors'...I don't want to do either of those.  I have great neighbors, I live in a corner house where a lot of people/kids walk...I just want to catch them.  Once I know who's doing it, I'll move the cameras to more visible locations (to deter others from doing anything else). Thanks for any help!

TSA Security and why George Orwell is the New Nostradamas

This is basically ripped from Digg, but I'd much rather open discussion here rather than over on Digg as Digg isn't a discussion, just a horde of comments...Travelers at Sea-Tac and dozens of other major airports across America are being scrutinized by teams of TSA behavior-detection officers specially trained to discern the subtlest suspicious behaviors...Such people are referred for secondary screening, which can include a pat-down search and an X-ray exam. The microfacial expressions, he said, are the same across many cultures. ...a central task is to recognize microfacial expressions....ArticlePerhaps you've read Orwell's 1984 - if you haven't, do so.He did not know how long she had been looking at him, but perhaps for as much as five minutes, and it was possible that his features had not been perfectly under control. It was terribly dangerous to let your thoughts wander when you were in any public place or within range of a telescreen. The smallest thing could give you away. A nervous tic, an unconscious look of anxiety, a habit of muttering to yourself—anything that carried with it the suggestion of abnormality, of having something to hide. In any case, to wear an improper expression on your face (to look incredulous when a victory was announced, for example) was itself a punishable offence. There was even a word for it in Newspeak: facecrime, it was called.Digg Linked HereAgain a link to the Surveillance map - in which we (US) have joined the UK, Russia and China as an Endemic Surveillance society...LinkHow do you feel about your privacy?I say this as I personally have almost nothing but contempt for the TSA.... I say that as someone that almost always gets extra screening - so much that almost all of my flight tickets of the "SSSS" designation (indicating you get special screening without anyone picking you out).

Must be logged in to email an Instructable to a friend

For some time, we've allowed anyone, site member or not, to email an Instructable to a friend or two simply by entering the friend's email address and clicking a couple buttons.  On Sunday, against our terms of service (see link in the footer), someone ran a script that hacked this feature to send out mass emails to a very large number of people.  And the emails looked like they came from us.  Not good!  I hate to say it, but someone used Instructables to send out spam. So, yesterday I updated the site to prevent this from happening again.  I changed it so you could only use this feature if you were logged in.  We're thinking about different ways to handle it, to still allow people who don't have an Instructables membership to share Instructables with friends, but limit it in some way to prevent anyone from sending spam again.  Once we've decided on the best long-term fix, we'll implement it and I'll post about it here.

I want to install my own home security system with cameras, keypads, electronic locks...? Answered

Building this massive fence around my buddy's house and it's going to have an electric opener on the driveway gate, so it will already need a keypad for that, but there will also be a smaller gate that I'd like to put an electronic lock on and have a keypad for that too. I have seen sone keypad intercom systems that tie into your phone system and let you open the gates from the phone and even forward to your cell if you aren't home and let you talk to whoever is at your door. I was wondering if there are any security system installer or enthusiasts in the community that could point me in the direction of some resources, websites, or brands for security system components and accessories and whatever you need to tie them all together. We are in a pretty rural area so I am not really worried about the window sensors and that whole side of it, though it might be nice to have the option later. What I really want to do is to have cameras in addition to the keypads and intercoms on the driveway and walking gates. I also want the info to be really easy to access from anywhere in the house, I.e. intercom piped into the phone as I mentioned before, as well as the video on the computer over the network and hooked into the cable so it can be seen on any tv in he house. Bonus if I could view/hear/control the equipment with my smartphone or computer at work. Basically what I need is like the K-nex of security/home automation electronics.

N64 security screws

Does anybody know how to open up an n64 without buying a special screw driver? I'm going to make an instructable on how to make a cheap, good, desktop power supply out of the n64 powersupply. If you look at it's specs it's pretty good for it's size! 3.3 volts at 2.2 amps and 12 volts at .8 amps. I'm going to but a boost circuit in and get 5 volts too (didn't want to use a 7805, if you're going to be using the 12 volts you want all the amps you want, plus what project uses 2.2 amps of 3.3 volts?). Plus I'm going to make it so that you can still use it as a power supply for the n64, and it won't be ugly.

Arduino bicycle security "system"? Or something similar?

After having my bike stolen I was brainstorming ideas on how to stop it from happening in the future. An idea I came up with is that, since I only leave my bike unlocked while going into a store, and I only go in with my friend(who also uses his bike), I would put an arduino board under each of our bikes.  There would also be a third "receiver" board that one of us would put in our pockets.  When the two bike boards are X feet away, the reciever as well as the boards would beep, flash, whatever. So, my question is, put simply, is this possible? Exactly as outlined? If not, how could I make it work and be similar, or at least as simple. If it is, could you point me in the basic direction of what I would need to do with the Arduino, or w/e you think would be best.
