Good to see someone else here decoster, and looking forward to seeing your list of parts.
My solenoids arrived this morning (from China, via eBay). I decided to go with the 19V @3.16A PSU I already had, since I can’t see any situation in which I’m going to need more than 8 solenoids.
So, I scoured eBay and found these 24V 300mA solenoids! Eight of them with never consume more than 2.4A, and running them at 19V instead of 24V won’t make any noticeable difference performance-wise.
