Hey, I have a question. Could the PIC in an SSC be re-flashed to handle plain DMX-512? I have an idea for an application that only requires about 50 pixels or so. That is enough to make it too expensive and too large to control via a DC DMX Dimmer, but much smaller than justifies an ETD. I've already posted a request for a couple of old USB dongles, but DMX USB dongles can be had off E-Bay for a small outlay. (Plus I have a couple of spares sitting around.)
If this works, I think there might be a demand out there for single or double string applications to a maximum of 170 pixels. I'm designing a decorative lamp fixture. Someone the other day mentioned wearable pixels.
