Opera 10.1 Upgrade FAIL!

Opera just announced the existence of a upgrade to it. I told it to proceed, shorty after I noticed my (usually silent) PC to spin its fans vigorously…

This repeats whenever Opera is restarted, so I had to delete the offending file somwhere in %TEMP%. Great engineering, guys!

Broken Kepco Power-Supply

One of the reference values is much  too low, note the brown and crispy Zener.

Update: Looks very shitty, but it works. I’ll replace those with real 6.2V Zeners the next time I order some electronics stuff.

Success! Even though I’m still scratching my head about the funny memory layout in graphics mode when using a 6x8 font. Time to read the datasheet (again).

Graphical LCD Controller

New project: Using a Atmel ATmega168 to control a graphical Everbouquet LCD that itself uses a T6963C Controller. Right now it seems that I can read the status-register and data successfully. The integrated DC/DC controller (for the negative LCD driving voltage) powers up and delivers –9V.
