Almost finished. Most of the day spent in the basement, working on the power supply. Will put pictures when finish it. Continuous regulation from 1.2V to 19.5V. LM317BT can give 1.5A. Nice for start.

Kernel panic? Server dead!
Well, my server with clarkconnect linux died a couple days ago. Kernel panicked and I didn’t have time to fix it. I just killed it, and installed IPCop instead. Works fine, so far. It’s an old box, Celeron 433MHz , 128Mb RAM and 4.3Gb HD. Little bit an overkill for the task, status said that average idle cpu is 98.79% and average free memory is 42.09%. Swap usage is 0 (zero).
So, that means that there is no more poprzen.pointclark.net. Gone. There is an extra NIC in the ipcop box for DMZ. Web server will be alive again, but not with clarkconnect linux. I do not have nothing against it, just want to try something new. Maybe gentoo, or debian? I don’t know yet. Have to find decent and cheap old box for it.
Scanner AcerScan 620U and Linux
How did I setup AcerScan 620U to work with SANE driver:
As a root, open file /etc/sane.d/dll.conf with your favorite editor (vi if you are on command line) and uncomment line snapscan.
Download firmware from www.benq.com. I can’t remember exact address, but search for “acerscan 620u” or something.
Save firmware file somewhere in your home. Let’s say, ~/scan/u96v121.bin.
In the /etc/sane.d/snapscan.conf put full path to the saved firmware.
firmware /home/goran/scan/u96v121.bin

Looks like that 620U is not supported on benq web site (or I couldn’t find it). So, after little bit of googling, found drivers on a www.nix.ru. After 12Mb of download, open zip file. A firmware file sits in a bin directory.
Welcome here!
After more than a year of using wordpress on my home server, I found out that nice people from wordpress.com are giving space to waste. Thank you, wordpress!
So, here I am, starting my new/old blog. It will take few days to move some of the articles. Also, have to notify people who were visiting the old pages. Well, it’s Christmas time, reason to contact them anyway. It will be fun here, I guess.
