I have had little problem with operating systems. I haven’t found any I could like or use. After Ubuntu 9.10 lost it’s support, and next versions of *buntu distros were all bloated and ugly. Back then I did not have needed knowhow to use other linux or unix systems, so I stuck back to Windows.

Dual buck converter
I had boring day, and was too lazy to do school works, so what else I could do but electronics? For next project I need power supply and due to poor efficiency of linear regulators, I choose to make an another switching regulator.
And there is the blurry picture. Similar construction to the nixie clock’s power supply, but this time double. Read More …
