I expect there are many of these posted around but thought I would show the one I made for my astroberry setup. Cost pennies and weights nothing.
I didn’t need USB power (Raspberry pi, dew heaters, guide camera power and data, DSLR data) in this unit. Nominal 12v input (better if regulated and stable under load) with fuse; power switch, LED voltmeter, two DC sockets at the supply voltage (for HEQ5 mount, Startech USB hub), and a variable/regulated buck-boost converter to supply constant 8V to the DSLR.
