The scripting and programming is mostly complete. Time to test the Kindle. For the purpose of testing, I set the Kindle to change screensavers every 5 minutes instead of every 3 hours. It works flawlessly for hours at a time, then fails. It always fails in the same way: displaying no picture in screensaver mode. Even manually pressing the button power twice does not solve it. Perhaps the Blanket program crashed or something, I don't know, but it fixes itself after a restart.
After hours of debugging I still cannot figure out what the problem is. Decided to call it quits, but added a recovery option should that happen. I installed KUAL and kterm, so that after a reboot I can manually run my screensaver changing script again.
Finally, I decided to consolidate both the script to change screensavers and that to download images. Here's the final masterpiece:
| # time to wake up | |

| # 50% probability of displaying pic or photo | |
| if [ `sed 's/[^[:digit:]]\+//g' < /dev/urandom | head -n 1 | awk '{print substr($0,0,2);}'` -lt 50 ] | |
| then | |
| # display a downloaded pic | |
| echo displaying a downloaded pic | |
| mv -f "/mnt/us/pics/`ls /mnt/us/pics -1 | head -n 1`" /mnt/us/linkss/screensavers/bg_xsmall_ss00.png | |
| else | |
| # display a photo | |
| echo displaying a photo | |
| cp "/mnt/us/photos/`ls /mnt/us/photos | sort | head -n 1`" /mnt/us/linkss/screensavers/bg_xsmall_ss00.png | |
| fi | |
| else | |
| # no pics currently, just change to a photo | |
| cp "/mnt/us/photos/`ls /mnt/us/photos | sort | head -n 1`" /mnt/us/linkss/screensavers/bg_xsmall_ss00.png | |
| fi | |
| /usr/bin/powerd_test -p | |
| a=0 | |
| while [ $a -lt 50 ] | |
| do | |
| lipc-set-prop com.lab126.powerd deferSuspend 86400 | |
| sleep 2 | |
| a=`expr $a + 1` | |
| done |
I've reset the screensavers to change every 3 hours instead of 5 minutes. It'll still be a few days before I present this to my girlfriend, a final few days to test and make sure it works perfect!
