Attempt to repair short on motherbord

At work, we had a small embedded PC that had a short in the mainboard. I attempted a fix, mostly for educational purposes. It wasn't successful, but I wanted to post the method and result anyway. The method I used is elaborately explained on Youtube, so go hunt there for more details. Read More »

New year’s resolutions

I updated my personal homepage at the beginning of the new year. Some of the changes were long overdue, like my university student status and the number of diving licenses. But, there were other changes that arose from a more recent insight: that, if I am to reach my goals, I need a plan. A bad plan is better than no plan. And too many goals are as useless as no goals.
