DIY ROV Submarine

This yellow submarine isn’t exactly the same one as John and Paul sang about but it is an extremely impressive DIY ROV submarine with built in camera.

Made completely out of PVC pipes with some pumps tossed in to help it move and sink, this project and easily be put together by anyone with some spare cash and time.

The entire sub is controlled by an Atmel Mega32 microcontroller. The video fee and system control is fed to the surface using a cable (they say that wireless video as well as leak detection and torpedos is a future add-on).

This is a great project that will bring you hours and hours of fun.

Exchange To Google Apps

Microsoft slaves rejoice, you can now migrate your entire company’s database of contact, emails and calendars from Microsoft Exchange to Google Apps. The tool, which is a small download from Google, works with both Exchange 2003 and 2007.

You do need to be a Google Apps Premier or Education Edition customer, but other than that it’s free and easy to use.

Microsoft’s set of web apps are just around the corner, I wonder if Google rushed this out the door in order to start putting a dent in the Microsoft corporate Armour.

Modded PSP Includes LEDs, Camera And More

What do you get when you take a stock PSP Slim 2000 and add a second joystick, 32GB of flash memory, a second port for charging, and a built in camera? A usable PSP, that’s what.

Of course the unit is running custom firmware so you can easily run every emulator under the sun and make the PSP usable. Check out the video after the break of the modder explaining what he did.

Alarm Clock App Knows When To Wake You

This might be nothing more than smoke and mirrors but the Sleep Cycle alarm clock claims to analyze your sleep patterns and chooses the best time to wake you up. You place your iPhone face down on your maters and the app analyzes your tossing and turning and figures out you sleep cycle.

I haven’t tried it yet, but for 99 cents I have already downloaded it and am ready to see if it will work tonight. I’ll keep you posted.

Arduino Powered RC Lawnmower

As a male who owns a home with a lot of grass there is nothing more I hate then cutting the grass on a hot sweltering day. Since my son is only three and he can barely reach the mowers handle I’m SOL with getting him to do it.

Maybe I should build this awesome radio controller Arduino powered lawnmower? I can just sit in a lawn chair and drink a beer while the Lawnbot 400 does all the heavy lifting for me. I would quickly become the envy of all the males who live on my street. Check out the video of it in action after the break.

This instructable will show you how to make your Arduino into an R/C interface that you can use for just about anything requiring remote control. I will also show you how I built an R/C lawnmower using my Arduino, a cheap R/C transmitter and receiver pair, and a couple of electric-wheelchair motors from Ebay. I have used this interface to control anything from basic LED’s to Bipolar stepper motors, mini-robots, lifeless R/C cars from the thrift store, and even a 100lb lawnmower (all with appropriate motor controllers). It is very flexible and easy to change and very simple to set up.

RFID Reader For Your iPhone

Benjamin Blundell built a hardware interface for his jailbroken iPhone that reads RFID signals. By patching in his homebrew hardware to his iPhone via a standard iPhone USB cable the reader detects low-frequency tags and will soon be able to read MIFARE tags as well.

You can bet you will never see this app approved in the official Apple app store, but just imagine how cool it would be to read RFID tags with your iPhone. Check out the video after the break

Handheld Gamecube Mod

Sure, we have seen our fair share of game console mods here at tech.nocr.at, but never one so shinny (just look at all those finger prints!).

The sweetest part of this whole mod is how Techknott hid the optical drive behind the flip-up LCD screen. The whole mod looks comfortable to use, just wish the finish was something other than chrome so you don’t have to be constantly cleaning it. Check the video out of it in action after the break.

Create a RJ-45 Cable Tester

DIY RJ-45 Cable Tester

Cable testers can be super expensive, but if your trying to trouble shoot a cable drop or run then you know how valuable one can be.

Our favorite kids over at Instructables have a great how to on building your own on the super cheap. A quick trip to your local big box home improvement store and your favorite electronics store (hell even radio shack should it all) and a few bucks is all you will need to build this.

Besides your basic DIY hacking tools you will also need the following …

8 LED’s
20cm of Cat5 Cable
9V Battery Clip and Battery
Wall Mount Box
2 RJ-45 Female Jacks
220ohm Resistor
Female RJ-45 Mount Plate

Once you have all your components assembled head on over to Instructables and make your way through all the sets.

Photoshop On Your iPhone

10 years ago most of us would struggle with not only the cost of Photoshop but the cost of the hardware needed just to run it let alone do anything with it. Amazingly enough in todays day and age you can now carry Photoshop in your pocket.

Alright, alright, it’s not CS3 or anything it’s actually 1.0, but it’s still super cool on the geek factor scale. This demo was released to about 50 people who recently attended the Photoshop 20th anniversary event and will never see the light of day on the app store. Doesn’t mean that I want it, I want it bad!

Check the video out after the break of Photoshop in action on an iPhone.

Glow In The Dark Toilet Paper

How many times have you been in the bathroom taking care of business when suddenly the lights go out? Never you say? Well I have, once. Trust me, when you are caught in a situation where you are in complete darkness the only thing you want to know is where the toilet paper is, and when the lights are off you have no idea.

Enter the glow in the dark toilet paper. If you are ever caught in a situation like I mentioned above you will be thankful that you spend $8 a roll (ya that’s right, cleaning up you business with glow in the dark toilet paper is expensive).

You can grab you very own roll at I Want One of Those

Roll Your Own 3D Video For Under $300

You’ve gone out and seen Avatar and now your ready to summon your inner Cameron and shoot the next blockbuster 3D movie but you just can’t seem to come up with the millions of dollars needed to purchase the camera gear you would need, fear now more because you too can now create a super-duper 3D film for under $300 (how was my infomercial pitch there?).

Some great weekend hackers have put together a shopping list of materials needed to pull this off.

A couple Kodak Zx1 Digital Camcorders
L-Shaped bracket
Some nylon washers, wingnuts and screws
A basic tripod

I’m sure you could use other cameras and adjust the bracket to suit, but the concept is pretty simple. They have a full write up on how the pulled it off including all the editing that is needed to produce the stereo image. Check out the video after the break of some home made 3D footage.

Brushduino – Arduino Meets Toothbrush

You knew it was bound to happen. We have seen Arduino’s used in everything from toasters to coffee machines and now we see the Brushduino. The cool hacks knows when you are brushing via an accelerometer that you attach to your toothbrush. By knowing what your doing the unit will tell you when it’s time to move to the next section of your mouth.

“It’s basically all LED’s. There are 6 white LED’s that correspond to the six regions of the mouth that I want to highlight, there are four green LED’s for showing progress and there’s a speaker I pulled out of some broken toy that’s there to entertain the children while they brush. The multi-strand wire connected to the three analog inputs on the Arduino also supplies 3.3v and ground to the accelerometer. The cable itself is an old ADB keyboard cable from my old Mac SE/30 from back in the day. It’s been laying in my junk box for ages. There are also some current limiting resistors for the LED’s and a bunch more of that lovely AWG30 solid core wire I like so much.”

WiFi Door Opener

We have seen our fair share of door opening hacks. Remember the secret knock door lock? That was pretty awesome, but what if I tell you that you can unlock your door from any wifi device?

The guys over at Sunlight Labs have done just that. By using a WRT54GL and some creative hacking that have wired up their wireless router to buzz open their front door.

So how does this all work? Well, let’s start with the router. It’s a Linksys WRT54GL, a still-Linux-friendly descendant of the WRT54G, the router which jump-started the custom firmware scene. There are a lot of custom router firmwares available — DD-WRT, Tomato, Gargoyle — and they can all make your consumer-grade router do some professional-grade things. For this project I used OpenWRT, the system on which many of those other projects are based. It’s got a much steeper learning curve than those other distros — you definitely need to be comfortable with the command line — but it lets you build a custom firmware with exactly the components you want. With some tweaking I was able to create a firmware that included a stripped-down version of Python, but which still fit into the WRT54GL’s meager 2MB flash memory. (Like the Arduino, Python turned out to be overkill, but at the time I expected to need it — and it’s always nice to have it handy.)

Boxee Set To Roll Out A Set-Top Box

Boxee Set-Top

Ohh you Americans with your awesome ability to watch full episodes of TV shows via Hulu and Boxee. Us Canadians are only stuck with the ability to watch our Canadian programming in some crappy player on some crappy Canadian broadcasters website. Actually it really isn’t all that bad, but then again, you have Boxee, we have awesome beer. You can always use a VPN is you really wanted to use it.

Boxee just announced that it will be releasing a set-top box that will run their fantastic software. There really isn’t much details on the upcoming device but then again all it really has to do is have a hard drive inside and HDMI out, no? It’s what’s inside that counts, the Boxee software.

Hopefully one day we will see Boxee up here in Canada with having to go through hoops to use it and with a connected device that costs oh let’s say under $200 to power it, you might never need cable or satellite again.
