Power supply for Gemini 1
Hello,
The power supply of my venerable Gemini 1 recently brouhgt down. Unfortunatly Losmandy sails no more power supply for Gemini 1 . Had somebody the same problem in the past? Is it possible to use a power supply for PC by changing its cable (using the cable of my old power supply) to have the good electrical outlet for Gemini 1 (4 pins , cylindrical outlet)? And what about polarity? Is there a risk of damage in case of error of polarity?
Thanks in advance for good advice.
Best regard.
Arnaud

Re: Interrupt message on HC with Gemini 1
I managed to get to site to look at this further. What was strange is I couldn't slew to anything to the West without getting an interrupt message. I checked the controller, and internals to make sure there was no corrosion. I also checked the battery condition which was 3.07 volts. I then removed the battery for 5minutes to clear the SRAM. After reinstalling the battery and entering all settings again everything was fine thereafter. My safety limits were way off which I manually set with the hand controller. Perhaps it was a corrupted model which was cleared properly, or the warm restarts caused the issue. I'm not sure what the problem was, but everything appears to be working now as it should.
I've been looking through the logs and didn't see anything that shows a goto limit issue, all Serial Received results show "MS, 0" in all logs for the past few days.
That might lead me to the controller causing an issue.

I thought goto limits was one of the reasons, but given the goto requests were nowhere near the meridian I ruled out that being an issue.
I have someone going onsite and will get them to check the current state settings on the hand controller to rule out any differences between what I'm setting and seeing in Gemini.NET; and remove the hand controller and try rule out where this might be occurring. May even swap the battery over.

Hi All,
Happy New Year!
Its not started well for me I'm afraid!? I have a quite old G1 (DIN motor connectors but with slide switch on/off) and it has worked perfectly for a very long time, with frequent use. However, tonight I fired it up and it immediately showed 'SRAM FAILURE' for about a second, then 'WD RESET' thereafter, plus some beeping. The menu system works, but in an erratic way.? I tried changing the RTC battery, which was fine anyway, but this made no difference. I changed the EPROM for an old one I had (known to be ok) but this did not work either.? Everything is permanently set up, in an observatory, I checked supply voltage, which is fine .
I then plugged in my spare unit, with the? same hand controller, motors and cables....this works fine. (so at least? I can continue observing)
Any ideas what this fault is?....it looks 'serious'.....but if possible I'd like it? repaired!

Re: 'SRAM failure +WD Reset' on Gemini 1
Hi Simon,
This problem can be caused by some hardware failures. The one that seems to be fairly common is the failure of a voltage supervisor IC, as described in much more detail by Brendan Smith here:

Re: Interrupt message on HC with Gemini 1
Ok interesting, Not sure ?how that might occur as I covered all ports with tape to stop any small bugs getting within the controller. Everything does feel ¡®buggy¡¯ lately.
I can slew to some stars from CWD and slew home and back to CWD without issue. It made me wonder if this was too generic an error and could account for something else in error that isn¡¯t documented. It¡¯s just weird and annoying.
It¡¯s only temporary whilst waiting for a new mount to arrive more suited for remote operation. When I get a chance to revisit site, I¡¯ll pull things apart and make sure no signs of bugs, corrosion are present and check the battery.
Thanks

Of course you have no real button as you are remote...but the Gemini got a signal or a glitch that it interpreted as a button press.? So it stopped it's slew.??
It should still know where it stopped...so try the slew again.
When you get to the physical mount, look for a damaged cable or a bug or corrosion in the handset, etc.? Something is generating that glitch signal.??
Of course, do not leave +DC power on the Gemini for a long period of time.? Moisture generates corrosion between dissimilar metals, but the rate of corrosion is greatly accelerated by DC voltage.??
Best if luck solving your?problem,

Of course you have no real button as you are remote...but the Gemini got a signal or a glitch that it interpreted as a button press.? So it stopped it's slew.??
It should still know where it stopped...so try the slew again.
When you get to the physical mount, look for a damaged cable or a bug or corrosion in the handset, etc.? Something is generating that glitch signal.??
Of course, do not leave +DC power on the Gemini for a long period of time.? Moisture generates corrosion between dissimilar metals, but the rate of corrosion is greatly accelerated by DC voltage.??
Best if luck solving your?problem,
And happy 2022 too,
Michael

I've just now encountered a constant interrupt message on the HC when I try to slew to stars around the sky with precise pointing and plate solving, sometimes some slews work others don't.
I can't work out why it's doing this, and I've never seen this before.
Everything looks to be Ok. I start Cold start from CWD, sync with GPS, and enter the correct site lat/long, I have the mount limits set to my best limits.
I am in the Southern Hemisphere. From south pole position, it will slew West to some stars, Ankaa, and Achernar.. but if I tell it to slew to rigel or Orion, the software says slewing, but the mount raises an 'Interrupted' message on the HC, and it doest nothing.
I'm using Gemini Level 4 v1.05 and the latest 1.0.84.0 .NET drivers.
Has anyone come across this HC message, or similar issue before?

Interrupt message on HC with Gemini 1

Re: ASI Air Pro use on Gemini 1
Hi Nick
Yes, the rpi is just like any other PC in that regard, you can simply reinstall the OS (Rasbian or astroberry in this case). You should be able to find instructions online by searching for "reinstalling raspbian on RPI" for example.

Hey Tino,
Hmmm...this may change my setup. I actually HAVE a rPi. It came with my telescope(used). The only problem is the previous owner couldn't tell me the password.?
Maybe I can dedicate the rPi to the G11 and simply use the AAP on another rig.?
By any chance would you know how to overcome a lost password on rPi? Maybe I can reflash the device???
Any further guidance would be greatly appreciated!
Thanks in advance

Re: ASI Air Pro use on Gemini 1
Nick you might just try downloading astroberry and installing it on your rPi, wiping the sd card in the process?

In a very general sense, yes. But ZWO took the Indian foundation and built apps on top of it, so it¡¯s customized to the point that you wouldn¡¯t recognize it compared to say ekos.?
AAP definitely has the self-contained feel. The apps are functional and work well together (provided you only use ASI cameras, focuses, etc. though it does work with other mounts including Gemini).?
However, if you want to do something else, you are stuck. For example, their version of PHD was pulled from the open source repository some time ago, so the latest features are unavailable and some basic capabilities are limited (e.g., no backlash compensation).?
For people who enjoy fiddling or tuning things, the rPi approach is probably a better (and less expensive) approach

If so it should be running linux with INDI, EKOS and KSTARS.
You will have to install the INDi Driver (INDI is the equivalent of ASCOM on linux) for your mount then.
They can usually be found on the github repo here (with instructions to install them):

Not having an ASI Air, I cannot say. You'll have to experiment, or contact ZWO for their ASIAir instructions.
The Gemini-1 uses only a standard serial port at 9600 baud to pass instructions back and forth. The Gemini sysrem takes its own instruction set. That instruction set was based on the earlier Meade instruction set. Paul K is the real expert in this area.
ASCOM has these instructions in it's Gemini.net driver interface.
If some other group member knows how these parts (ASI air and Gemini-1) all fit together, please let us know the right way for Nick to proceed.
Happy holidays and a safe New Year,
Michael
Michael and Howard,
Thanks for the reply. It did take a few reboots to get back on track. It¡¯ll be a week or so before we have clear skies to test the system.
Are there any concerns running the Gemini 1 on the ASI air pro platform? I¡¯m not plugged into a laptop or hand controller when running.
Thanks
Nick
