I bought it back in 2013, and it's been sitting in its box since (aside from a few short trips out). So I figured I should do something with it...
Links are (relatively) large JPEGs.
Fan is an 80x80x80 San Ace counter-rotating fan, 12V (because I had it lying around, and it provides good static pressure for use with the filter). Tach outputs are plugged in, but power is from a separate DC-DC converter, as I didn't know the current limit of the board (also: a 24V fan is $70; the converter was $12). Fan speed is controlled via the knob; current range is ~.3A - 1.5A (fan maximum is 5.5A; 1.5A is loud and agressive, 5.5A is hilarious). Photo 5 LCD display is minimum speed, with fan 2 being the inlet. No internal photos, as the thing was so hard to put together I didn't care to pull it apart for a photo. And the wiring is an awful mess. It's not terribly quiet, but it's not bad, and it'll stay cool and clean (the AEM filter is good for 1-2 years between cleanings). Everyone needs a hobby (and I need a different one).
