[Lowfer] need a circuit for DC...

[Peter Barick]

Hi All,
For Andy's P-S needs (~36VDC, low I) I'll 2nd Ralph's though on the HP printer supplies. And it should also appeal to Andy's expressed sense of recycling, as I recall, and mine too.

Those I found (with the disgarded printers at curbside) are of the tabletop variety and require a plug-in AC cord. They also have some weight to them, hence not likely to hang well from a wall socket. But mine sit unused as I hadn't found a use for that high DC output (ya, but some day!).

Cheers fellows -- Peter
