Quadcopter in the Gustav Vigeland Sculpture Park

I’ve installed a CopterControl board from OpenPilot in my home brew Quadcopter.

It’s pretty impressive stuff.

The camera is a 808 HD. And the build log is in Norwegian: Part 1 and Part 2. Here is the Google Translate version: Part 1 Google Translate and Part 2 Google Translate.

Link to video on YouTube.

Now I just need to buy a GoPro HD Hero 2. I’ve already ordered a stabilizing mount.

Cost and flight time

$200,- for the quad (frame, motors, speed controllers etc)
$100,- for the Copter Control Board
$25,- for a 2500 mAh battery giving 10 minutes for flight time
$70,- for a second hand Futaba 8U radio

Build time: approx 10 hours

Time spent learning how this stuff works, learning to fly, waiting for parts from china: don’t know…

How to make that cardboard ‘hood’ for the DIY bokeh effect

Earlier this year I posted an article about how to make your own “bokeh” in your images. People have asked me for details about the cardboard “hood” I’ve been using.

So I decided to simply tear it apart and put it together in front of my video camera. Three minutes and fifty seconds later. And there you are. A nice tutorial on how this was put together.

How to build an amazing lantern of ice

Yes – completely off topic regarding the internet, media centers, marketing and new media. You know, the stuff I usually write about here on eirikso.com. But it has been easter holiday, cold and I’ve had several days off.

First, ensure you’ll have a couple of days with sub zero degrees. Preferably something below -5 degrees Celsius (23 F). Then fill a big bucket with water. Find a smaller bucket and place it in the water in the big one. Find something to put in the small bucket to make it submerge in the water in the big bucket. Don’t use water in the small bucket. Use small stones or something else. I found a part of wood.

The small bucket will float around in the big one, so you might want to tie it up to make it sit still in the middle of the big bucket. You need about 5 cm (2 inches) of water around and under the small bucket.

Now leave the bucket outside for a couple of hours. I needed about two days in -5 to -10 degrees Celsius (23 – 14 F).

When it is completely frozen remove the weight in the inner bucket and fill it with hot water. This will melt some of the ice to make it easy for you to remove the inner bucket.

Depending on the temperature you might need to pour some hot water outside on the big bucket as well. To be able to remove it.

When removed, make some holes along the end. When you place it on top of a candle you need some air to flow into it. When finished, light a small candle and place the block of ice on top of it.

Now wait for the evening to arrive and have fun watching these amazing lanterns.

But the heat from the candle will melt the top of the lantern! Yes, but it will keep looking cool. 🙂
