Bad Motivator Build Log
So, I have been working on this for a while now.  I have had several things pull me away from this challenging upgrade.  However, it is time to start logging this so, I can have a record.

This is my attempt to get a billowing plume of smoke that is present when R5-D4's motivator goes bad.  Right now, I am dialing the electronics.

I go from the 12V battery to a 30A relay that is controlled by a simple 3 seconds on 10 seconds off Arduino sketch.  The voltage is then stepped down to 3.7V via a 30Amp regulator.  Through testing, Iv'e found I can stick a 30Ohm 5W resistor in line with the 6V aquarium pump to supply proper voltage to it. 

The .18 Ohm heater draws about 76 Watts and about 21 Amps for this three seconds. The heater coil is rated up to 80 W.[/font][/size][/color]

After serval design attempts.  This one is the simplest and most elegant.  It uses a scotch yoke mechanism to raise and lower the Bad Motivator.  All of my spring loaded attempts left me with the trouble of resetting the system.  This way it is all software controlled and I can run it without fear of losing panels as they go flying off.
