New Arduino project

June 19, 2009

I found myself a new Arduino project – an automated car!

The 4x4 wheel RC TruckWell how to go about this. My best approach was to get a cheap RC toy car from the local toy store, not a real RC car from a hobby store, but one of those really cheap ones. I will probably scrap the electronics any way. So I found my self the proud owner of 4×4 wheel cool truck, with rubber wheels large enough to driver both outdoor and over my doorsteps.

The old electronics - Only H-bridge stearing - CRAP!Next was to get the Truck disassembled and find out if any of the electronics could be reused. When opened I could see from the layout of the components that it was build around an H-Bridge with four transistors for the motor control. This means that it can only control the direction of the motor (Forward / Backwards) and not the speed – not ideal.

Gearing for left/right control - CRAP!Also the wheel turning was based on the same Principe with only all the way to the left or all the way to the right (a small motor with gearing controlled this).


Then how to control it with the Arduino?

The old helicopter partly disasembledWell one way is to use servos and power controls (acts like servos) and the Servo lib.

And I accidentally had this lying from an old helicopter I crashed some years ago – newer throw anything away right! 🙂

So this adds up the all these peaces in the below picture.
  • We have the disassembled truck with body and covers etc.
  • We have a couple of mini servos from the old chopper
  • And the speed regulator from the same servo
  • A Charger (not shown) and a battery pack
  • AND off course not to forget the Arduino Duomille board

All the neat pieces layed out nicely

That’s all for tonight, I will continue with the assembling this weekend if I get the time.

AND naturally keep you posted!

The Challenge 2008 – Win some nice prizes

January 6, 2009

With this somewhat of an outdated title, I would like to inform all of you about the Microsoft game competition running this month. The competition utilizes the Messenger API, to write simple games to be played from within Messenger. You can write your own game in flash, Silverlight or pure html, and via JavaScript communicate with your Messenger client to make it a multiplayer game.


I have been chosen by Microsoft to be one of the judges – bribes are not accepted – but I encourage all to participate in the game development tournament this month. 


Read all about it at 


I think I will make a little game of my own, but naturally I can not participate in the tournament. I will keep you posted about the progress.

Google Street view is coming to your iPhone

October 7, 2008

Macrumors has looked at the upcoming iPhone Software 2.2., and according to them the controversial Google service Google Street View is on its way to the iPhone.

In addition to the Google Street View the new software update is expected to have support for “background push”, as an alternative to background processes. Also it is expected to have a feature where the user can turn off the built-automatic spell checker, a feature more than 20,000 irritated users has requested.

Look out for the 2.2 firmware in iTunes soon.

Try out the new iPhone Spore game from EA games. Its really a time ribber, I’m at level 19 now. So when its raining in Copenhagen you can always play Spore from the couch.

Pocket projector – I want one

October 2, 2008

The American company 3M has made a mini-projector that can blast a picture at 50” 4:3 format picture.
The size is very pocket compatible, only 11 x 5 x 2 centimetre, and 152 grams. At a price of only 2800 DKK, I want one! – Don’t know for what thou!

On national TV

September 30, 2008

This morning I went on national TV for the first time in my life – quite an exiting experience. Naturally I had my concerns last night before I vent to sleep, but with a hectic morning, most of the stress and fear went away.

I was on the morning show at TV2, one of the most viewed programs in Denmark, and together with Anders Hjort from The Danish Electricity Savings Trust, we showed the new Web portal My Home. My Home is a web portal for home energy savings, and home automation, we have made at Hello Group over the past year. A very big project containing everything from automatic online power meter readings, to savings advice, a full scale floor plan drawing program, and integration with real live home automation, where you can monitor and control your home appliances at the touch of a button on your computer or cell phone.
As the show was live there was little room for mistake and screw-ups, and even thou we did experience some technical difficulties during the live run. Everything went well and the light turned on in my apartment (we had live broadcast from my living room directly available in the TV studio).

All in all a nice experience and something I believe will make me stronger for future presentations. I have always admired the people on the show, where its obvious its there first time on TV, and have had the mantra that if I could appear on national TV, without making a complete fool of my self, I thing I can do anything.

Judge for your self.

Office 2007

August 1, 2007

It’s nice with Office 2007, this makes it much easier to post new blog entries. Just write them in Word, insert pictures and hit ‘Publish’. That is all there is needed. Or so I hope… Well if you can read this you will know it worked. Hopefully this will encourage me to become a more active at my blog.

Let’s try with a picture too.

Microsoft Surface – There is no spoon!

June 13, 2007

Have you seen Microsoft Surface and its flat screen touch technology?
Have a look at it at

At first glance it look really smart, cool and sexy, even thou it resembles a lot the technology Apple launched half a year ago. At closer inspection, it is quite a charsel in the sky. No doubt we are moving in this direction but it WILL take a lot of PC power (graphical and processor), especially if it is to run on Windows , and how to overcome the link between the phone and the “table”, just by placing it on the table? Bluetooth? Well how is it to distinct between a piece of cheesecake on the table and my phone emitting Bluetooth near by? And what about devices with no wireless output, like iPod, Cameras etc.

Well time will tell. For now it’s just good inspiration. 😉
