I found some great tutorial videos for you, if you are new to filming underwater.
Check out these 2 videos from videojug! Nice walkthroughs.
The guys over at the Raspberry PI foundation just announced that they will be coming out with a cameramodule for the Raspberry PI early next year.
With 1080p 30 frames pr sec, and a 5 megapixel camera module that connects to the Raspberrys unused pins with a ribbon cable. Its still not in production due to some possible inteference issues on the ribbon cable, but it looks like this might be the coolest expansion board yet for the PI.
Imagine all those robots around that needs a good video link, and all those hackers that want to take use of a cheap prototyping tool like the PI with 1080 video! This is excellent news for those prototyping geeks, and 2013 will probably be full of different hacks with this module! Cheap wifi video links, and other cool applications at the price of 25$!

I have a Probotix Fireball V90 cnc and as i live in an apartment along with others i want to be nice to my neighbors and my girlfriend.
So i decided on building a wooden box with insulation for it to collect dust, and remove some of the noise.
Here is how i did it.
18mm Mdf plates cut into 95cm x 95cm sizes. Put together a box with it.
Cut the front plate in 2 to create a door.
Put in 30mm thick car insulation sound mats from our local Biltema.no in norway. They are made for insulating cars and boats and such and comes with adhesive stickers on the back.
Added some hinges for the door, and a hole for cables.
I have not meassured excactly how much noise it removes but i will guess about half of the noise from the dremel on 30.000 rpm , and about half of the stepper noise. Very pleased with this build so far. Next thing is to fly the machine on large rubber straps to remove vibration!
I ended up using all 8 1m x50cm isolation mats and i still need more in the back but that will come later
I guess this removes about 30-35db of noise in total. I bet more goes when i remove some of the vibrations. Very happy with this build so far.
Got the Mdf for free from a friend, so the only cost so far was the isolation mats that cost 159NOKR pr 1mx0,5m x 8
And the hinges for the door
It has a live webcam in there and the picture below is live, when it has power. If the picture is completely dark its night-time and the cnc and the rest of the neigborhood is sleeping, or i have forgot to turn the light on inside the box. Lights will go back on when its in use!
Here is a short youtube video of it in action.

I am constantly trying out new tools to build all my crazy prototypes and the biggest tool of all has been a CNC for some time now.
I bought the electronics for it, over a year ago and finally it was time for ordering the rest of the cnc parts! They arrived after 2 weeks from USA.
Probotix has made a CNC machine named Fireball V90. Its a pretty small sized hobby CNC, but it has definitly alot of potential!
Here is some pictures of the process of putting it together!
I also ripped apart an old Magni composite/component signal generator i found laying around the office, and used the cassis to build a new home for the stepper motor controller and the power supply.
I also made a emergency button of an excisting button on the front panel. Probably going to use the rest of the buttons for CNC control later! Thank you Magni.
My divebuddy has taken some pictures during the last 4 dives this weekend when i tested out the new gopro dive rig. Still have some adjustments left to do, but it actually works brilliant now! I am going to add a second light when it arrives in the mail as well as try out different kinds of diffusion filters for the lights.
By the way, my dive mask makes me look evil underwater!

The divelight im using as both diffused videolight, and my normal divelight without diffuser is this one from dealextreme.com
Extremely good LED light for very little money! Cree dive light 100lumen 4AA LED – 27$
I have written forum threads on these sites about the gopro rig as well
Made an improvised ipad mount for our new workout ellipsemachine. It looks pretty awesome. Just found a piece of wood, drilled
Holes and wired it up with steelwire. Added a couple of steel angle brackets and wrapped them in black gaffatape to not damage the ipad. Works like a charm. Add a headset and youre ready to go.
Just made it through an entire Dexter episode!
I just wanted to share my divelog on the Movescount website. Im currently using a Suunto D4i divecomputer to log my dives, and it works like a charm. Considering buying a pressure sensor to log my air concumption as well, but its a bit expensive that thingie..
check out the dives here.
So im working on the optimal way of using my gopro hero 2 under water and im trying to build a cheap rig with lights and handlebars.
Im using th blurfix flatlens housing from SNRprototyping on my gopro.
Lights are from dealextreme. Cree 100 lumens dive lights. 27$ each. Im adding diffusionfilters to get rid of the hard spot look. The difffilters are made for cinemalights for broadcast.
Gopro mount i sketched in google sketchup and printed on my makerbot 3d printer. Aluminium profiles was bought on my local Bauhaus store for 20$.
Work in progress…
Had a nice shallow dive at Lysaker brygge today.
Dykkersport served free waffles to everybody and I was a bit late, but still managed to team up with some dive buddies and had my first dive with the wing west and the Apeks stuff.
Logged my dive with my Suunto D4i dive computer.
You can see the log here.
Had a mishap with the drysuit, as i managed to fill a bit to much air in it after a while and as the bottle got more empty i got a few kilo less weight, and i got air in my legs and went upside down up to the surface. Tried fighting it bending the legs as usual, but it was to much air so i just went straight up anyways. Luckily it was a shallow dive and no harm done. Went down again to safetystop and stayed for a while berfore surfacing.
The sun has arrived in Oslo, and we had a wonderful 30 degrees sunshiny day today. Water temp was 11 degrees celcius at top and alot less down at 11meters.
I had my Gopro with the blurfix flatlens with me, but the visibility was so poor with about 2-3meter free sight, so it was not any point of filming anything.
