Quote:The wireless gamepad, usually a Logitech, is the usual solution. Not only can you move the scope with one, you can map various NexRemote functions to the pad's buttons, including tours, etc.

I think I have uncovered a new way to have my cake and eat it too.Since this is, at its core, all about remotely driving my CGEM mount from a dedicated imaging/observatory PC/Laptop from a warm "enclosed" position some 40' from the pier... While not having a rats nest of cables, controllers, dongles at the pier.Lets consider this:Step one: I take the HC, and put it away, safe in its foam lined box.Step two: I run a 40' serial signal to the mount on the pier over a Cat6 cable and a homebrew Celestron PC Port Converter...Step three: On the PC/Laptop I run my copy of NexRemote to drive the mount over the wire in step two... I will use NexRemote, to store alignments, park the mount, hibernate, etc.Step four: On NexRemote I activate a virtual port and I use that to link to TheSky (since I really like that point and go interface)So far that is pretty straight forward right?Step five: So I'm thinking how to I align with a tethered PC running NexRemote that is about 40' from the eye piece... Wireless GamePad anyone? I'm sure one of the geeks at work is likely to have something that I can borrow and test.So lets see:Less cabling (at least at the pier)? CheckLess things to setup and take down at the pier? CheckEngineering Elegance? at the pier Check... at the PC? Not reallyOne less unsecured kinda expensive sensitive gizmo to be left outside? CheckWill it work? testing underway... I wonder what the max range of a wireless gamepad is...So close and yet so far away...
Quote:Been doing this for multiple years now.. I use a Logitech F710 wireless remote, nexremote with theskyx talking to the virtual port on nexremote. You can even have nexremote connect to your favorite serial over wifi device, skysafari, skyq, bluetooth, etc.

Yes you and I are on the same page... other than I plan to run mine on a permanent pier... And I have a laptop with an actual old school serial port...
Are you building the converter with a perforated board... or are you etching a customer Printed Circuit board?
If you are etching... I would love to see/share your PC design... I'm on the road to build a etched PC board next week.

I'm new here and this is my first post. I was hoping you could answer a question though.
I've got Parkinson's disease and the tremors that go along with it so I try to avoid (or at least minimize) soldering tasks. I'd like to try making this homebrew AUX-to-PC port adapter on one of those prototyping boards using sockets, pins, posts, and wire jumpers, etc. rather than soldering and then if/when I get it working I could drizzle it with epoxy to 'lock it down'.
With that in mind, I was wondering... based on what you know now would it be possible or advisable to try to leverage one of the prefab serial to TTL (or USB to TTL) interface modules found on eBay or are they not suitable for the application? Could the right prefab module (maybe one that already includes the 5 V regulator) be wired with the 74HC125 chip to streamline construction?
I saw that this was the root of your original question that kicked off this thread but I didn't see that this possibility got pursued or investigated. Is it worth exploring further?
I wonder why Celestron stopped making the auxiliary port accessory? It was definitely the easiest way to add a PC port to a Celestron mount. It's not like they wouldn't sell!
Thanks in advance for your time.
