25 Feb 10 Minecraft
I’ve just recently discovered this awesome game. It’s a combination of Garrysmod/Cortex Command/Dwarf Fortress/Clonk, and Blockland.
To keep it short, you mine blocks to get different materials or building blocks. Then you can farm, hunt, craft etc. That is if you bought the game and get to test out the indev version. If you haven’t bought it, you can try out the survival mode. Or the sandbox single-player or multi-player where it’s all about building and digging. Which is also very fun, especially in multi-player mode. Read more about the game here.
To keep it short, you need to give it a try!
A few screens:
Overview of my farm, on the walls are torches to light it up when night time comes sneaking.
The “inventory” where you can see my armor, and all my slots for weapons etc.
24 Dec 09 Merry Christmas!
And a happy new year!
26 Nov 09 New stuff arrvied! :D
Yupp, just a short little update.
I got the RF sender & receiver from Sparkfun today!
RF Link 2400bps Receiver – 315MHz
RF Link Transmitter – 315MHz
Also a 20×4 serial LCD, gonna be useful for advanced applications. Anyhow, if you got the RF kit, and was like me wondering how to get it working. I found this nice guide at LMR.
Now it’s just to find a nice way to use the RF links, it’s only one-way communication, but it’s gonna be awesome to use it as a remote for one of my robots!

15 Nov 09 Forums are back!
I’ve just set up the stigern.net/forums again, mostly for discussion around some of my guides and projects. But feel free to post and discuss other stuff.

14 Nov 09 My Arduino Robots
Thought I write some about my two robot projects! They both use a Modified Pico, since it’s the smallest Arduino I’ve found. And it also fits on a small breadboard!
Botty 2:
This is the most advanced robot I’ve built, but it’s not nearly finished.
It’s current task is to drive straight forward until it senses a object with it’s IR-sensor, then drive away from it until it’s cleared, and continue in that direction. Really simple 
It uses a Sharp-IR sensor, mounted ontop of a servo, so it scans the horizon while driving forward. The sonar in the picture isn’t in use, since I actually like the IR sensor better.
BewBit:
Simple and yet fun to make arduino bot. Just follows the strongest light source. Using two LDRs, a modified pico and 1xAA and 2xAA battery packs, to give out 4,5 volts. Just enough to power theSN754410 and motors. But it gets around. It also includes a low-voltage alarm, which beeps when the voltage goes low.
Had a little accident, it drove over a carpet, or it came about 30cm into it and some funny gear-whining noise came A lot of hair in the gearbox, had to take it apart and clean it.
Future plans:
* Crash sensor, a small micro switch in front.
* Speaker, plays sound according to light source
* Better code

14 Nov 09 Thinking about starting with Arduino? Read!
Hi
I just want to write a few words for those new to Arduinos, or those looking for tutorials, guides etc. If you haven’t got a Arduino board yet, you can get one from several places, I’ll list some of my favorite shops. And of course you also need the Arduino Software!
Or, Modified Electronics for the great Pico! (not recommended for beginners, you’ll be better of with a normal board).
What you are looking for is the Arduino Duemilanove, the USB board. Which will suit most your needs. It’s very easy to use, and wires can be plugged right into it. Later on you might want a Boarduino or maybe a Pico as mentioned above, they are great for using in combination with breadboards! Alternatively you can get the Starter kit, almost all shops got these. Sparkfun got a nice kit, which is worth a look.
If you should want more I/Os, or just more space for code the Arduino Mega is a great choice! Or the Sanguino!
Parts!
You will always need parts, resistors, leds, breadboards, wires etc. I’ll list up a few shops that I use the most.
Lots of cheap basic parts! recommend the resistor packs, and they also got cheap breadboards. And all of the shops mentioned above stock parts too. For jumper-wires I recommend these at seeedstudio. Futurlec also got some nice jumper-kits. For extra small breadboards these at Seeedstudio are very nice!
Great site for robotics, motors, gearboxes etc. They also got a nice tracked chassis. They got a lot great products, sensors, motor controllers, etc.
Tutorials/Guides/etc
1. The basic guide, from sparkfun. You should start with this!
2. The Complete Beginners Guide to The Arduino
3. Adafruit’s Arduino Tutorials
5. Arduino.cc Reference! Not tutorials, but handy!
Also the Libaries page at Arduino.cc is great! I’m sure you’ll find something to use in several projects!
Well, thats all I’ll write for now. I’m sure I left out alot, and will update this post when I find something new to add 
PS. If you got any questions etc, please take it in my forums post here.

12 Nov 09 My new Serial LCD arrived!
Got my Serial 16×2 LCD today, I’m still quite noob when it comes to serial. But I’m gonna put out some simple and easy to follow tutorials for stuff when I get the hang of it
Anyhow, here’s just a little youtube clip showing some of my projects today!

30 Oct 09 Arduino: Showing CPU load with 9 leds!
My new project, is a simple led-strip which shows CPU load. 9 led’s are used for this, could have used more but my tiny breadboard couldn’t hold more. Anyhow, it uses serial communication to receive how much the totalcpu usage is. For this you need a C# program running on your computer, it just sends a value from 0-100. And the Arduino reacts and lights up leds accordingly to how much load your CPU got.
I will not go into how you make the program in C#, therefore I’m uploading the .exe here for you to download. I’ll also include the source-code for it.
What you need?
1x Arduino
9x LEDs
Some wires
1. Wire it all up like in this Fritzing picture.
2. Load up the Arduino with the following program.
3. Download the C# program here.
When you start the .exe file, you only need to select which Com port the Arduino is using. And the click connect, and then it should start communicating with the Arduino. And show cpu load.
PS. If you got any questions etc, please take it in my forums post here.

14 Jul 09 Modified Pico, a Arduino Nano, but smaller.
Look at it?!
I just fell in love with it Also, 24$ isn’t bad. So if you’re considering the Arduino Nano, why not try this one instead?
Features:
ATmega328 running at 16MHz with external resonator (0.5% tolerance)
On-board FTDI232 USB to Serial Connection
Supports auto-reset (choose Duemilanove w/ ATmega328 in the Arduino™ software)
Operating voltage of 2.7 – 5.5 VDC
Schottky diode reverse polarity protection
Auto-sense power input between USB and external source
Resettable 500 mA fuse for overcurrent protection
On-board pin 13 and communication LEDs
Go check it out =)

24 Jun 09 Bo/arduino advanced light tracker.
Made a followup to my light tracker, except this one can go up and down. So it follows light in more directions than the other ones.
Made of some cheap plastic-foam, wont last forever but long enough for me to test it.
PS. If you got any questions etc, please take it in my forums post here.
