My Summer Of Projects is plugging away nicely. The CNC router is nearing completion, and I've added a CNC precision mini lathe project next in the lineup, to be dedicated to short run production, ~4 hours per week. The lathe is at the local UPS hub and will be delivered tomorrow, and the stepper motors and drives and power supply will be here a few days later. I just ordered the motherboard, RAM and SSD.
I've been getting the Intel D525MW motherboards and I'm liking them so far. I'm putting 4GB of RAM on them so they shouldn't need to swap to the 64 GB solid state drive. All of that makes for a compact and fairly easy installation in an electronic panel for this embedded LinuxCNC application, but then I need to power the computer. On the router project, I used an ATX power supply, but it's big and bulky. The oddball hole pattern is awkward to mount on the subpanel, and there's a huge rats nest of power cables and connectors that I don't need. I considered opening the power supply enclosure and pulling the cables and connectors inside if there's room. Opening the case might make it easier to mount the power supply as well. The guys who use the D525MW for mobile media players have power supply modules that snap into the power connector on the motherboard and are powered by 12 VDC, but it wouldn't do me much good if I needed to mount a power supply to power the DC-DC converter. I suppose the DC-DC converter provides enough isolation that I could use some extra capacity from the DC supply that's used to drive the motors, but I'm not crazy about that idea. I want a transformer for isolation. I wish there was a small (100W?) 120 VAC PC power supply, preferably with no fan, that plugged into the motherboard and had one pigtail to power the SATA solid state drive. I looked, but couldn't find one. Any suggestions?
