thinking of white widow seeds I have already, dutch passion. should give it something interesting to timelapse!
the failed SD card issue started to re-emerge yesterday and the new Samsung SD card got screwed as well and the pi wont boot
Bit of a pain but again all the latest changes were backed up already so not too much grief.
led me to wonder why its having these issues, one suspect I had was power supply, if it doesn't hold up under the load and you get a low supply voltage during write operations, then the SD card can end with failed sectors. enough of those and the OS wont boot eventually. Googling around a bit I found some others have seen such issues with supply issues.
I rethought the power a little bit, taking off the capacitance I'dd added to the 5V rail (power supply turning off too slowly can also cause SD card issues), and removing the 5V feed from the control box. I also clipped the 5V red cable on the hub, so the Pi is on its own now, with a 3.5A 5V adaptor and high current mini-USB cable supplying it directly.
with this setup I've done some tests again on the old SANDisk card. Seems its too far gone, it keeps corrupting even after low level format and fresh install. develops issues quickly.
the Samsung on the other hand , showed only few errors on the original filesystem. After a low level format it seems to be operating well (im keeping an eye on it with fsck regularly)
so, hopefully cracked it this time.
just did something else to re-organise things for the better also ; got the OS running from the hard drive rather than SD. Now the SD is just there as it needs to be to redirect to the HD at bootup. this should help things also.
heres a very good instruction :

Its a fresh install again, so gonna take another day to get everything back where it should be.
Other than that things were looking good, about to start some tests. still , better it came up now than in a few weeks hey !!
