I decided to try out a windmill costing ca 180.- USD that will arrive any day soon. It is quite windy here I live, so I should get a decent 500-1000W out of this and with a decent battery bank I should be able to drive a lot of out-door electricity – not connected to…
A common problem with plotting lines in raster graphics is visualization errors as we display the graphics. Most times we can just ignore these, but as I am drawing scrolling real-time plots I also receive the side effect of an integer error.

I have so far never seen a performance test where C/C++ did not win an easy victory due to it’s nature, but I am very curious about what I see in front of me now. The failure I pointed out earlier is how .NET or Windows behave then you push it to it’s limits, but…

I have searched for Web Designers a few times and recently found Google Web Designer. This is a full HTML5 designer with WYSIWYG designer as well as Code Editor. This looks like it could be the answer to my web design needs should I decide to use my own time to dig into this. Google…
I basically keep my notes here in this blog, so to follow a project you just click on the project in the left (obs right) bar as that will filter out entries. This is so far the only real change to this blog as I keep searching for alternative themes. I actually found one WordPress…
One of the things you need to be aware off as you design (or use) a CAN based protocol is how arbitration works and how it can be used to your advantage or create a timing bug if it used wrong. CANbus consist of a 11 or 19 bit ID field at the head of…
