I did some experimentation, and my blade lock-up sensor is compatible with the MR clash sensor, meaning I can hook-up my lock-up as a replacement to the clash.

This also means I now have to change the driver & LED of my prototype saber to accomodate a MRFX board so I can film the result and show you guys.

As far as I can tell, from the trial and error on the MRFX, if you clash longer, the clash FX is just trigerred over and over, so the lock-up should in theory be credible. Still have to do more testing.

Helas, I'm moving and all my saber stuff is boxed already.
