Zalman mini-Aleph

ojg · 13th January 2008, 03:33 PM

A couple of years ago I bought some of BrianGTs mini-Aleph boards. A few months ago I finally built them. And here is the result.

They use a Zalman CNPS 7000B-Cu LED as a heatsink. It's very efficient even with the fan at minimum, and works as a nice power-on LED to boot :-)

The power supplies are two 12V/50W switch mode units.

The casing is an IKEA pencil holder, 10cm on each side.

The pictures are taken while doing the first power-on test so please ignore my test-speaker :-)

Thanks to Nelson Pass, GRollins and BrianGT for their work!

Very nice

Very cool!!! I'm sure it makes a nice hand warmer too.

Nice work.

I have some of those fans (without leds), and they work well.
