xtm,

with your electronics skills, you could have built the entire DC speed controller with only a few more components.

You can build a 555 based Pulse Width Modulator circuit which uses a IRF510 Power mosfet to controll the current to the powerhead. You would just add a 12Volt wall wart supply that can supply the PH.

I have one sitting in front of me that I intend to put in my hood to control the moon lights & fan speed. Since I have four channels & only using two, I could control two of those waveboxes. Oh, and my 4-channel PWM is accessible via ethernet & programmable.

Very good job!
