Haha, yeah, it's gonna take up some space, especially considering I'll have 3 of these 42V's and a 36V.  
Well, I couldn't resist doing something since I'm home sick with the flu today. I get bored pretty quick, lol. 
I soldered up one of my boards with the mounting clips for the LDD's and everything looks good.
 
I'm wanting to steal a bit of power from my power supply units so I got some HRD DC converters. But they come stock with set resistors and I want to switch them out for variable ones so I can adjust the voltage I need depending what I want to power up. For instance my Arduino , my cooling fans, etc.
So here's the converter I have:
 
and the back:
 
and the variable resistor I'd like to use:
 
Any insights as to how to wire the variable resistor is greatly appreciated.
