I know Jim stated that the adapter that we received with our original Hyper SaberSD boards a couple of months ago allowed for it to be used with other technologies besides the Hyper Blade. If you plug in the adapter to where the Hyper Blade would normally sit, you then have like 5 or 6 wires that you can solder to a Luxeon, an LED drive, a rumble motor, etc. We've been told that it is usable with a Makatosai blade, but I don't think anyone has done one up yet.
Not sure if you would have to resistor it or whatnot, as some of the others who are more "techy" than I am might be able to clear that up, because the Hyper SaberSD works between I believe 6-14.4V
Might want to try and get up with Matt (Jedibum) over on the Hyper forum if you have questions. I believe he has done a couple of different variations with the Hyper SaberSD.
