*Will use a large PIC, probably 16bit, possibly dsPIC33 for higher pwm frequencies, and better analog.

*Hardware
**USB mini jack along with a broken out pinheader, for internal connection to the motherboard
**the ability to drive 6 PWM fans, 4 of which should be analog driven trough a simple buck converter(design below) for 3pin Fans versions
**all six should have a 500mA capacity
**two additional PWM 4pin drivers for pumps,(2A) shouldn't be an issue, cause our board will only provide the PWM, and RPM sensing, the computer PS will power them.
**6 analog inputs (Temp sensors)
**8 digital I/O (5v tolerant)
**5pin universal interface like Bus Pirate
** possibly incorporate a cap-sense button support
**Universal LCD connector with as many pins as possible to support as many LCDs
***contrast and backlight adjustment)

*Software
**Possibly make it cross platform(windows/linux)
**Setup utility
***configuring of all the outputs inputs and such. something like a picture of the device with pull down menus next to the pins.
**Control/monitoring Wiglet where simple options could be modified, like Fan temp profiles, what to display on the lcd...
***Widget should show all relevant sensor data along with Computer PS voltages, and overall consumption of the board, possibly individual consumption
**Part of the LCD smartie source code and the LCD backpack source could be used, cince lcd smartie already taps stats/emails..and has button support.

*Buck converter Idea
[http://geoffg.net/fancontroller.htmlGeoff's intelligent Fan controller]
**only using a higher frequency (~0.5-1Mhz) for the pwm, to use cheaper/smaller caps/inductors, A shotky would have to be added
**perhaps use Seeed's led driver IC 500mA one, that is used in the Rainbowdino, it could be cheaper then the one used by geoff.

*New parts used
**Fan Module
