I did, you order many boxes from a place called CDI. Then
Step 1 - remove old minis from your show.
Step 2 - Throw them in the trash can
Step 3 - plug in the DIY mini repair devices (also know as new LEDS)
step 4 - Run out of time to get show ready and not do one! (really, really, cuts down on show work.)
Done!
No mini lights to worry about fixing anymore! LOL
Yeah I know its not what you were looking for. I am unaware of any DIY buzz boxes. Those units are nice but kinda of expensive. most people use the light keeper pros.
