Propeller DC Dimmers & Ethernet / DMX Bridge

Hi!
I thought some folks might be interested in some Christmas decoration hardware I designed for this year.
We ended up with two products based on the Propeller chip: a flock of 24-channel, high speed DC dimmers and a two-universe Art-Net to DMX bridge.
The code for both projects hasn't been posted yet, but it was all easily compiled using snippets posted in the object exchange. Thanks to JonnyMac for some LED driver bits, DynamoBen for an Art-Net template (it's been a few years now!), Tim @ Brilldea for the Wiznet drivers, Beau for sharing his PWM_32 code, and many more.
The DC dimmers control the light panels on the house itself. The Art-Net bridge feeds these DC dimmers, as well as some RGB uplights. The Art-Net bridge is based on the Spinneret ethernet module, with the addition of a ribbon cable-connected daughtercard for output.
Once the silly hardware bugs were worked out - which took two PCB revisions - everything has been rock-solid. There's no better feeling than installing your gear, then never worrying about it again.
Thanks, Parallax, for such a powerful and flexible platform. And thanks to this community for your support and ingenuity.
