Hi, Really good write up - thanks! I had a similar experience with my Pegasus UPB in that when I connected it to my mount computer, the computer wouldn't accept other USB inputs. At that time I was using an old EQDir cable with the Prolific chipset. I replaced this with a new FTDI based adaptor and as far as I can tell everything now works as it should. However, I do use the Pegasus USB hub in preference to the mount computer so my EQDir does come from the Pegasus hub. As everything seems to work, I haven't really done any more testing so this is far from definitive but I suspect the problem was more to do with the old EQDir cable rather than the Pegasus. HTH Regards, Hugh

Or in my case, to move a little piston up and down......................

OK, Windows sucks! Now then, lets have a go at Linux. Let's see I think I'll try..................... Elementary OS, Linux Mint, Arch Linux, Ubuntu, Tails, CentOS 7, Ubuntu Studio, Open SUSE, Fedora, Bodhi Linux, Mageia, Kubuntu, Mandriva, Deepin, Budgie, Ubuntu Mate, Sabayon Linux, Crunch Bang Linux, BackBox, SolydXK, NixOS, KaOS, Pinguy OS, Peppermint Linus OS, Ubuntu Kylin, AV Linux, Scientific Linux, Alpine Linux, aptosid, Russian Fedora Remix, Kantofix, Lunar Linux, Void Linux, Grml, Caldera Open Linux, Parsix, TurnKey Linux, LliureX, Yggdrasil Linux, VyOS, Debian Pure Blend I got bored at this point. Is it really any wonder that even people that would like to try Linux give up!

There are some really good books on learning to use a lathe. Genuine guides for beginners that get you started. I taught myself in my sixties - at least to a level that gave me enough skills for my own needs. I have never seen any books that could do that with Linux. Regards, Hugh

Beginner: how to solder RCA socket to veroboard?
hughgilhespie replied to choochoo_baloo's topic in DIY Astronomer
Hi Matthew, Just a note of caution here. Using RCA connectors soldered to Vero board is NOT a good idea. It takes a fair amount of force to insert and remove the RCA plugs and all that force is being held by some very thin copper strips. Sooner rather than later the connector will come adrift from the Vero. It is a really good idea to use chassis mounting connectors and let the box or whatever take the strain. I know that there is an enormous amount of equipment sold that have the connectors soldered directly to the pcb, I have some myself, but that doesn't stop it being a very bad design. If you intend to mount your circuit in any sort of a box, then for the sake of drilling a hole or two in it, you can have much improved reliability. HTH. Regards, Hugh -
SGP Framing Mosaic Wizard not working
hughgilhespie replied to symmetal's topic in Discussions - Software
I am so pleased to read these posts!! I am a total beginner at using SGP and I experienced exactly the same behaviour yesterday - a very uninformative error message. Naturally I assumed that this was me doing something daft. I spent hours uninstalling, reinstalling, watching Jared's you tube video, etc. And then - IT'S NOT MY FAULT!! Phew, Hugh -
These are photos of my homebrew motor drives in my Pulsar 2.2 metre observatory. The motors are controlled using the Lesvedome ASCOM driver software. I used stepper motors but most people use basic geared DC motors. The shutter drive is powered by a 26 volt LiFePO4 battery. When the dome is in the parked position, the battery is automatically recharged. The dome drive motor uses power from a mains-driven14 volt 20 amp DC PSU. The shutter drive connects to the main controller via wireless, using XBee modules. The main controller has a safety system built in that performs start-up checks for the dome and shutter latches and shutter battery voltage. It also connects to a Hydreon rain sensor and a cloud gauge and will close the shutter if unsafe conditions are detected. I am happy to try and answer any questions if anyone would like more information.
