How many of you use a case with a cooling fan and also confirm adequate power supply


I have the RPi 4b ps and a case with a cooling fan/heatsinks on cpu, usb controller and ram.
There’s quite a difference between active and no cooling, check this video:

I'm using a Vilros kit: power supply, case with fan, and heat sinks. No problems, working great so far.

Experiences Using SM Beta on RPi 4, 4GB #43848
Wi-Fi hot-spot strangeness solved (?).
So.. I was struggling with the stellarmate hotspot...
It was flaky.
SM 1.4.4 version was a bit special in this respect but 1.4.3 did work.
I did work indoors but every time I took my rig out for real shooting the hotspot would disappear or become unstable or refuse connections.
I blamed neighbors, power supply, etc.
To tell a long story short - it was the USB hub interfering with RPI4.
Indoors I had RPI4 and the hub away from each other.
Outdoors I velcro them together - in this arrangement the hot-spot is not really operational.
If I power off the hub - the hot-spot works fine.
RPI3 is not affected by the hub.
Just reporting...

1.4.4 is flaky for me.
In 1.4.4 KDE UI was very sluggish. KStars/Ekos when started were OK/fast.
And the hotspot situation is still a mystery to me.
In 1.4.3 the hotspot was also doing tricks but at least I made it work...
I realize, those are beta releases...
(RPI3 is rock solid/stable).

Thanks, that's useful to know. What kind of case is used for the rpi4? could this be a factor as well?

Regular plastic case sold with CanaKit. For RPI3 I have clear/transparent, for RPI4 - black.
Could aluminum be more resistant?

Similar thing happens with RPI3 (didn't check with RPI4) and my 10" LCD/HDMI monitor which I use in the field - if I bring it closer than 20 cm to the RPI - hotspot dies.

Wi-Fi weirdness continues...
So, I put RPI4 away and continued to successfully using RPI3.
Tonight I gave RPI4 another try.
It worked! Indoors, outdoors. With the hub away or right next to RPI.
(SM 1.4.3 Mate. No updates. KS 3.3.6)
Shooting outside right now.
Puzzled.
Maybe it depends on which channel it broadcasts/connects?
It's set on Auto.
Is there any way to tell which channel it's connected to?
Figured this out.
Right now it's on channel 1.
Mount's wifi is also on channel 1.
All other wifi sources use channels 3 and up.
Thanks!

I found the WiFi on the Pi4 using Raspbian and it's default WiFi to be poor, I had to position the Pi4 just so to get it to connect.
But once I had got AstroPi3 to do it's magic, which includes installing a different communication system, it seems much better.

Had to disable the timeout method of setting a hot spot as it started immediately instead of waiting 30 seconds.

Argh...
Yesterday, everything was fine. Finished around 2am.
Brought everything inside.
Today, exactly the same setup. No changes.
Same wifi channel. Same neighbors.
Brought outside.
Worked for about one hour.
Then, in the middle of polar alignment, the mount lost connection to the SM hotspot.
I couldn't restore it.
Gave up and switched to RPI3 (takes 5 minutes).
Go figure...

OK. I give up on WI-Fi connection from the mount to RPI4's elusive hotspot for the time being. (RPI3 is fine in this respect).
Made an EQDIR cable ($8 total cost).
Works reliably.

^^^I flashed a spare SD card with 1.4.4 and also couldn't get the WIFI to work. Luckily I still have 1.4.3 on the other SD card and the wifi works flawlessly on that.

Max,

Can you please specify what you bought/soldered/etc to make your cable? I just failed in my attempt to build a cable to connect my RPi4 to my Orion Atlas Pro -- (I do have a shoestring cable I bought, but I'd like to make backups).

Hy
