Re: INDI or ASCOM Alpaca?
Ray Gralak
So what do people hope will see happen with increased support for Alpaca or INDI?
toggle quoted messageShow quoted text
For example: 1. Just document the specs and let the LINUX and Mac developers figure it out? (I think developers may be disappointed with this because most of the cool features in APCC require a lot of work that will not be included in command specs and many features don't use any of the undocumented commands) 2. More MAC and LINUX applications? 3. Ability to run APCC and other apps on a Raspberry Pi 3 or other small low power computer? 4. Have the ability from ASCOM applications on Windows to talk to standalone Alpaca devices? 5. Have the ability from ASCOM applications on Windows to talk to devices on other computers running LINUX or Mac/OSX? 6. Other things? -Ray Gralak Author of APCC (Astro-Physics Command Center): http://www.astro-physics.com/index.htm?products/accessories/software/apcc/apcc Author of PEMPro V3: https://www.ccdware.com Author of Astro-Physics V2 ASCOM Driver: https://www.siriusimaging.com/apdriver

Re: re greasing worm wheel on 1100GTO original gearbox.
W Hilmo
I actually worked as a baggage handler for an airline for a while, and my father was an airline pilot.
I am pretty sure that all of the Boeing and Airbus airplanes are fully pressurized (but not heated), even in the cargo holds. The reason is that it’s easier structurally to pressurize the entire fuselage (except for areas that cannot be pressurized, like the landing gear bays), than it would be to have pressure bulkheads that isolate the cargo holds from the pressurized area. For this reason, I would strongly suspect that the same is true for any modern jet aircraft, even from Embraer, Bombardier, etc.
As it said, it doesn’t affect your point about shipping grease, but it caught my attention because lots of people believe that the cargo areas are not pressurized, when they actually are. If they weren’t pressurized, you could pretty much assume that any kinds of liquids in your checked bags (shampoo, toothpaste, etc.) would make one heck of a mess on every flight.

Hi Wade,
To answer your question, I Googled the question – “Are aircraft cargo holds pressurized? “, and got several answers, about temperature and pressure conditions in cargo. There are two cargo holds - one part right behind the crew cabin, may indeed be made liveable, for pets, and live (lobsters) restaurant food shipments. The “aft cargo” hold isn’t likely to be – no need for the extra T & P conditioning load for “dead-weight” items. Meanwhile, sometimes “stowaways” survive such high altitude conditions when they stuff themselves into aircraft wheel wells.
As for the “loosely capped” ASG-33 lube grease tubes, I wouldn’t want to risk travelling on a plane, not knowing if a dealer shipped this (Amazon purchase) product in the aft cargo, and whether the high altitude pressure drop causes outgassing and pops the lube cap. There probably are cargo fire extinguishers in there, if it should ignite. (Somewhat, kidding ?)
Anyway, such products being shipped must surely require a signature, declaring that they are not hazardous, but then it is a matter of the shipper’s opinion. I’ve probably exhausted the case for lube shipping concerns here and I am confident AP takes the appropriate common sense measures and precautions, to safely ship its special lube, where possible. So perhaps, we shouldn’t expect the lube product to be made generally available everywhere. Wonder if even the CONUS postal services or truck transports, have any special concerns or restrictions, handling such materials.
As for where potentially combustible petro-chemicals might be “unknowingly” stowed, as cargo or luggage - Hard to predict, but surely hazardous or out-gassing products wouldn’t share the same pressured and temperature controlled, animals (liveable) forward cargo area. Here below, are two of the search results:

Re: re greasing worm wheel on 1100GTO original gearbox.
It was sent to me in Belgium without problems whatsoever, it is only a small quantity of grease in a small plastic container.

“At the risk of muddying the waters, I also wonder, if the “AP Special Mount Grease” formulation is even permitted to be shipped overseas in air-cargo, given that it is potentially a fire hazard, possibly explosive canister in the high altitude unpressurized airplane cargo hold. “
I agree that there might be shipping restrictions, and the rest of your points, but I am curious. Which airplanes do you think have an unpressurized cargo hold?

Re: re greasing worm wheel on 1100GTO original gearbox.
Well, Google is fine when you use it with site:*.co.uk or site:*.de (and so on) options for limiting the search to such domains only. Currently unavailable.
We don't know when or if this item will be back in stock. Derzeit nicht verfügbar.
Ob und wann dieser Artikel wieder vorrätig sein wird, ist unbekannt. On the other hand you will then find these hits for the AeroShell 33 grease: It woull also be nice to know, if there's some difference with AeroShell 33 in blue tubes... ..and in green/cyan tubes: https://www.airpart.co.uk/assets/uploads/part/33CTG.png Naming is the same for both products so I hope there's no difference in contents, because I have ordered the blue tube grease from Transair.co.uk now: AeroShell Grease 33 - 400 Gram Cartridge Code : 2833C All in all, it's not that easy to pick up a suitable grease for my AP 1200 GTO mount outside US.

Re: re greasing worm wheel on 1100GTO original gearbox.
Joe Zeglinski
Harry,
It should be just fine, even if the AeroShell Grease-33
canister were stale-dated.
After all, the wear & tear on the AP mount’s worm gear isn’t nearly the
same as on a jetliner’s massive landing gear retraction and wing flaps
mechanisms, for which the grease is normally used.
Let us know if the date on the Amazon-sold tube that
finally arrives, actually is out-dated. Wouldn’t want others to go through the
hassles of AP mount gearbox removal etc. for lubrication with less than a
perfectly stable grease.
I recently learned a similar “Amazon Quality” lesson,
when I bought a large box of hard to find, Full face (small centre hole) AVERY
DVD labels. Turned out that the box of labels was VERY old unused stock, from
some music company’s shelf, and the labels backing adhesive was out-dated –
according to AVERY specs. They didn’t stick well to the media, messed up the
Laser printer rollers.
I think there could be a lot of unscrupulous dealers out there, peddling
left over junk, and hiding under the guise of Amazon’s presumably good
reputation.
Caveat Emptor, as they say.
At the risk of muddying the waters, I also
wonder, if the “AP Special Mount Grease” formulation is even permitted to
be shipped overseas in air-cargo, given that it is potentially a fire
hazard, possibly explosive canister in the high altitude unpressurized airplane
cargo hold. Might be limited to only local “CONUS - courier
truck-shipments”. That may be why the original poster can’t get this AP product
in Italy, unless the unique AP formulation is mixed right there, on the AP
dealer’s store premises, using locally obtainable “lube component”
supplies.
Hopefully, there is a solution. Otherwise,
AeroShell Grease-33 is certainly an AP-recommended, excellent alternative, and a
lot easier to source and buy world-wide from a local ... airport supplies
service center.

Thanks Joe. I saw the date as well, but thought I’d risk it anyway.
Even though Amazon is be a bit more expensive for Prime items, the flexibility to return items, easily, is worth it to me. Worst case, I end up where I started. 😊 Take care, Harry

Re: lost wifi from GTOCP4
Bruce Donzanti
well- looks like something with the CP4; I just tried my iPhone and another IPAD and neither are showing the network as an option. In addition, it appears and disappears on my iPAD and when it appears, it will ask for the password and eventually accepts it after several tries, connects to only disconnect a few seconds later. It is just repeating this cycle.

Re: INDI or ASCOM Alpaca?
Thomas Swann
I agree, Michael, if the mount commands
are fully documented, A-P can devote their resources to whatever
they see fit, and if something new pops up or A-P's choice doesn't
fit their needs, then people will be able to write the software
that does what they need. Making information like that available
fosters an environment where people can create new innovative
solutions. That's good for AP and the users. thomas

Re: lost wifi from GTOCP4

I turned the iPAD off and then back on. Then I did the same with the CP4. It took a while for the GTOCP4_Net_XXX to pop up but is now asking for the password. I have not done that in over 2 years. I entered it as I recall, my numeric number of my CP4 without the zeros, followed by admin12345. It will not accept it.

Power cycle the iPad and then the CP4. An Ipad sometimes get into a state where they don't discover new devices.

Re: INDI or ASCOM Alpaca?
Ray Gralak
Hi Dale,
toggle quoted messageShow quoted text
Okay great. I am looking forward to reading your blog after you get a chance to post it. And yes, I think there is a possibility of supporting both INDI and Alpaca. The dilemma is that Alpaca's driver interface is not available. Thus, even if an A-P Alpaca driver is created other manufacturers might not want to create new drivers until ASCOM can create a driver framework. Then after a critical mass of Alpaca drivers is reached it might then make sense for application developers to create non-Windows applications for Alpaca.

I turned on SkySafari on my iPAD to connect to my mount as always. It connected then disconnected, then asked for my password and now is not even showing up as a network option on my iPAD. Any suggestions as to why I cannot find it? This is the first time this has happened since I set it up over 2 and half years ago.

Re: INDI or ASCOM Alpaca?
Ray Gralak
If sources are available for the Alpaca driver it would be a possible option.It's up to Astro-Physics if the source code will be open source. But I don't think some of the things you said you are interested in would be in the driver. Most of the non-trivial logic in APCC and PEMPro is not something that would be in an Alpaca driver. It's application level code, not driver code. -Ray Gralak Author of APCC (Astro-Physics Command Center): http://www.astro-physics.com/index.htm?products/accessories/software/apcc/apcc Author of PEMPro V3: https://www.ccdware.com Author of Astro-Physics V2 ASCOM Driver: https://www.siriusimaging.com/apdriver -----Original Message-----
