Re: Using Pi to auto-align a Goto mounted Telescope

If you're willing to duplicate the handset's databases and functionality on the pi then, yes. If you want to use the scope's handset for GoTos etc then ...

Could you use a Serial to USB adaptor/cable ?

Gordon77
Yep. Or a level shifter. What you can't do is connect them directly to the serial pins on the gpio connecter.

Re: Using Pi to auto-align a Goto mounted Telescope

I've also given this some though but have yet to do more than that. As I understand it the process would go something like this: Get GPS co-ords, date and time and send to handset. Select alignment method (this may need to be done manually on the handset) Select first aligment star/object Take wide ...

Re: Servoblaster Help!

Last time I used servoblaster, you ran it once and supplied all non-default parameters you wanted to set. For example:

Code: Select all

sudo ./servod --p1pins=3,5,7,11,13,15 --min=60 --max=230
The easiest way to save this config is to write yourself a short shell script and run that instead.

Re: Samba Server Problems

Samba maintains its own user database seperately to the linux one. Have you added your user to that?

Take a look at the man pages for smbpasswd and/or pdbedit for info on how to do this.

Re: SAMBA: Win7 sees shares and files, but can't add, create

Is your USB drive formatted as one of the FAT varients (e.g. FAT32)? If so check what mount options you're using, especially umask, dmask, fmask, and maybe uid. Also check that the partition is being mounted rw and not ro (applies even if not FAT). The "mount" command will lst all current mounted dr...

Re: RPi as SAMBA server for Windows backup access denied

Check your samba config file and make sure that the share is not set to read only. Also check the permissions on the files/directories that you are sharing.

And of you're sharing a FAT partition from the Pi check the mount options too.

Re: Samba

Couple of things to check: 1. Is the share configured as read/write? The default is likely to be read only. 2. Which mount options did you use with your USB stick? mount will list the current ones. Make sure that it has been mounted with the rw option. If it's been formatted as fat32, you'll probabl...

Re: Can not connect via Samba from winxp

Try changing preferred master, domain master, and local master to no or configuring samba to act as a WINS server (I forget where as I usually use SWAT to manage my config).

You may also want to make sure that your pi and XP systems have the same workgroup set.
