I finished another 8 hours of testing (consisting of 740 subs) on the Minix and its Transflash/microSD card slot. I used 10s, 60s, and 240s exposures with a QHY5III-178C under Sequence Generator Pro. All was okay.
It also appears as if the update to the Windows Creators release (version 1709) has improved the performance of the wireless display feature that I documented in post #74 (at the below link):
As a review, the wireless display feature is built-in to the Home version of the Windows Anniversary release (and later) and it uses a very simple setup and it does NOT require that you have an existing wireless network, it's basically a point-to-point WiFi connection and it works without any third-party extensions. It's almost like a version of Microsoft's Remote Desktop, but for the rest of us who don't have Windows Pro or for those who don't want to setup a WiFi network. It doesn't support file sharing but it does provide a remote connection over WiFi to a virtual desktop with full graphics and keyboard/mouse support (and sound). However, it does require that the connecting client is running Windows 10 (so no support for iOS, or Android, or the Mac OS).
One thing to note, in the above link I talk about using a keyboard script that will allow the Minix to auto connect to the remote PC. However, I probably didn't make it that clear that you do NOT need to use that script if you keep a keyboard connected to the Minix (just a keyboard, you don't need it connected to a display). With the keyboard you can just type the three key strokes that you need to perform on the Minix when it first boots in order to establish the Wireless Display session (and this is a one-time process, but required after any restart of the Minix). And these keystrokes are not really timing dependent, they just need to be done after the Minix has finished booting to its desktop. Once that is done you can disconnect the keyboard (if you like).
Another 8 hours of more of tests done with the Minix and its Transflash/microSD card (and no problems, knock on wood). I was even able to image for a few hours last night and the Minix worked flawlessly (while using the Wireless Display feature of Windows for remote WiFi access). However, I did have some problems with Sequence Generator Pro (SGP), but that problem is something that I've seen before even when not using the Minix or remote access. It was the often reported issue of having SGP hang when trying to stop a short exposure from the Focus and Framing tool. It may be related to the camera's driver and I think the newest releases of the drivers and SGP have lessened that issue, but I'm still running software from earlier in the year so that problem bit hard last night (requiring me to force quit SGP on an number of occasions to get out of its endless "downloading" state).
Well, that and the fact that SGP is ridiculously slow at saving subs to disk. It's more than just a relatively slow download from the camera, it takes SGP five or six seconds to save a 12MB sub even though I can measure 60 to 70MB per second writes to my Samsung Pro microSD card. It's almost like SGP is buffering its writes in 1 or 2KB segments which is never going to be that fast except on an ultra-high performance SSD.
If my analysis is correct (which it may not be, I haven't seen the source code), then what the programmers at SGP need to do is change the code so that it reads from the camera as fast as possible into a series of DRAM buffers, followed by an aggregation of all the data from that sub into a single image held in DRAM, followed by a single write to disk for the entire file (in my case, the full 12MB). If they were doing that then I suspect it would take less than three seconds to both download the data and save the file (now that process is more like 8 seconds long).
