I spent some time over the weekend assembling power boards and Arduino shield. You can see the results on the following two videos:

No, it's not used. Over time I switched from AC power input to DC using affordable AC/DC modules. But the power module still offer both options. More information about power module can be found here:

I see. I asked because I need to rectify the output from a transformer for a ~48 V unregulated CNC power supply, and diode bridge rectifiers demand somewhat large heatsinks. So I was curious of how the ideal diode controlled performed.

Anyway, when I have some money and free time I think I'll give this project a shot!

Thanks, regarding ideal diode bridge rectifier a LT4320 (http://www.linear.com/product/LT4320) should be a safe bet. Here is one discussion about it: http://www.eevblog.com/forum/projects/bridge-rectifier-made-with-mosfets/

This looks really nice! I've been searching For a bench PSU lately, and I think your design is great. It acommodates a variety of use cases and it is capable of supporting a nice set of high end features. One question, were you using an ideal diode controller in this design?
