I was wondering the way to put the Raspi 4 onto my telescope, Noctua is a good one to avoid vibrations ... Have any people resolved vibrations to the telescope with fan ?

If you look at the link in my last post, the case I designed allows for a Noctua fan on vibration isolation pegs. It can mount on my telescopes with a standard synta/finderscope mount. I don’t notice any vibrations with the fan running at 5V.

I was considering that too. I have seen some PoE designs that have a hole through the center of the PCB.
Anyhow, I was thinking a side-mounted or angled fan might be possible. In my experiments, the underside of the Pi4 could use more heat dissipation.

esb, how about 3D printing a snug, TPU-based sleeve to hug the focuser ring, and then have gear teeth on the outside? I printed something like that to provide extra grip on one of my prime lenses (not for gearing though).

We probably should create a different thread on the VPN issue....
WiFi Connection dropped on me again Sunday night. I used a lightning-to-rj45 dongle to connect directly. Oddly, the UI said I was still connected via WiFi, but perhaps the act of directly connecting reset the configuration. I disconnected and reconnected for good measure, and no problems the rest of the night.

I don't know what cameras you are using, but I cannot recall ever having a connection issue with my QHY5L-II-M and Ekos. The 163M took longer, but as I alluded to, the QHY drivers took a long time to mature across all platforms. I do seem to recall someone having an issue with other combinations of QHY cameras. Yeah, I have mostly stuck with Indi/Ekos to have a compact solution while travelling with my gear, and I use an iPad Mini to do most of the control.
A few people have attributed connection issues to underpowered PSUs, so you might see if you can give it some more juice. There was a recommendation for a while to put the cameras through a dedicated, powered USB hub. While using my Rock64 SBC, I used to do that (Sabrent USB 3 , 7 port hub).
If you want to troubleshoot it, there are people here to assist. The output of "lsusb" and "dmesg" is often useful to know if the computer is even recognizing the devices.
Regards.

Jeff Wilson replied to the topic 'Kstars crashing on RPI4' in the forum. 1 month ago

Although I probably cannot provide specific assistance, can you describe how it is crashing? For instance, is the VNC connection still active? Do you see Kstars disappear, or does Ekos just disappear? If you run "ps -aux" from a terminal do you see kstars? If you restart kstars/ekos after the crash, does it seem to reconnect to all equipment? Immediately after a crash, if you run "dmesg" from a terminal, what does it say?
I fought with my QHY 163M for a year, and it seems more stable now. I don't know how mature the drivers are for the 128.

I have been using Ekos/Indi for a few years now, starting with the AstroPi script. I have a QHY5L-II-M and 163M. I frequently had "stability" issues, but it is hard to say whether this was from indi/ekos or the QHY drivers themselves (after all, QHY's EZCAP_QT will still crash on my on my PC and Mac). Or was it my hardware, since I was using SBCs? I used a Rock64 setup until recently, and on that Ekos/Kstars would certainly crash now-and-then. I just got a Raspberry Pi 4 and installed Astroberry, but the weather has only been decent once. Everything seemed to go smoothly until .... Best I can tell, the vnc server died or wireless networking died while I wasn't monitoring the session, according to the logs. My sequence completed though, and I got an image of the Atlas comet before it broke apart.

Let me know when you have a version with QHY linking, and I’ll give it a spin.

I've been using an arduino nano and 28BYJ-48 Stepper Motor for a while (there are a few projects across the web for this), but that requires an extra USB cable to the Nano from my Rpi/Rock64. I might have to give this a try. I think I have a NEMA motor hanging around somewhere.

Jeff Wilson replied to the topic 'Pi4, USB3, and Wireless 2.4Ghz interference' in the forum. 2 months ago

My RPi4 just arrived today. Revision 1.2. Yup, there are some serious WiFi issues. My 5G WiFi kept dropping while trying to install the AstroPi3 packages from @rlancaste. Only use connection was keyboard and mouse to USB2. I read a thread about QWHD resolution HDMI causing the problem, which I was running at the time, but changing the resolution to 1080p did not help the cause. I grabbed a network cable and made a direct connection to my router (satellite) to finish the process. This makes me nervous about sustained use in the field, or even from my backyard via WiFi.

Yes, the RPi ecosystem has always been nice, and it took a while for Rock64 distributions to become stable (if they can be called that now). I seem to be accumulating SBCs. The RPi 3B+ couldn't handle my USB3 camera very well at all, so the Rock64 filled in for a while. I think Pine's development team (perhaps just 1 person) have moved on to Rock64Pro and other hardware.

Anyhow, thanks again for putting together your script.

Jeff Wilson replied to the topic 'Rock64 Resurrection' in the forum. 3 months ago

I've been using my Rock64 with Armbian for over a year now using your previous script. Ron, I am reading this message pretty late, but I didn't know you were having issues. I cannot recall if I had to do any tweaking. Regardless, INDI/Ekos would crash on me occasionally (never sure if it was a USB3/QHY163M or Ekos issue). Getting WiFi running on the Rock64 has been a hassle. The weather has been horrible for imaging the past 3 months, but I am getting my gear setup again, so maybe things are more stable now. I also have a RPi4 on order.
