Hi all, just thought I’d share my latest creation to further simplify the number of components in my setup.
So, my current rig requires 3 devices for my imaging session.
1. A computer to run kstars/ekos (I currently use the Asus tinker board)
2. A powered USB hub (because my USB3 cameras suck too much power and the Tinker box would not run them without additional power)
3. Astroberry focuser (running in server mode with a Raspberry Pi 0W) which connects to Asus tinker board via indiserver) to focus.
My mount connects to the Asus Tinker Board via Wifi. Eventhing is controller by remote desk topping.
My latest creation is the "ultimate" single box device which uses the current Raspberry Pi 4 (4G version) computer. It eliminates the Astroberry focuser running in server mode and the powered USB hub. Everything is inside a HighPi Rapsberry Pi 4 enclosure (see
raspberry.piaustralia.com.au/products/hi...ry-pi-4-model-b-case).
I also installed a cooling fan and heat sinks to keep everything cool. Under full load I'm only seeing temperature of 59 degree C with ambient temp of about 26 degree C.
I have all the wiring for the Astroberry focuser which runs a DRV8825 motor controller connected to the Rpi4 GPIO. I also fitted a 12VDC to 5VDC 5Amp buck converter inside, which powers both the Rpi4 (i soldered the power supply directly to the RPi4 board, do this at your own risk!! see picture) and the Astroberry focuser.
I connect my Astroberry focuser to the motor using RJ12 plug.
And that's it. Everything runs beautifully and I reckon this is the ultimate mobile rig.
