אני מקוה שזה יצא לפועל :)

ולמי שלא רשום זה:

G'day all,

I've embarked on a project to build a you-beaut, full-featured, cook-your-dinner-and-screw-your-wife-for-you digital fan controller and monitor. My general goal is to produce a unit which will have up to eight temp sensors, eight speed sensors and eight variable voltage fan power supplies. User interface is, at this stage, going to be via a 2*16 char LCD panel (cheap, readily available) mounted in a 5 1/4" bay, and a set of microswitch buttons that let the user navigate through the screens, adjust settings etc. I want to have the user able to preset target temperatures, fan voltages or target fan RPMs; preset a few different profiles, such as summer and winter or loud and quiet, overclocking and stock etc; calibrate the fans (eg RPMs at max voltage, voltage and RPMS just before dropout, voltage vs rpm curve etc); and select a few different types of monitoring screen, eg one screen with summary speeds of all fans, one with summary voltages of all fans, and one with summary of all temps, as well as a set of detailed screensto display and adjust each fan and temp. At this stage, I'm planning on using the PIC 16f877 or 18f452, they've got plenty of grunt and (more importantly) 40/44 pins each. The code will be difficult, as there's lots of stuff happening at once, but maybe you guys can help me with that. I've already been asking questions about voltage control, you can see the discussions here . I've pretty much decided on PWM controlled voltage regs as the best way to do it - resistance controlled voltage regs put out too much heat, rheostats would be impossible to control digitally and straight pwm to the fans kills the ability to speed sense. Any further comment on this would be welcome.

What I want to know from you lot is, what else do you want to go into it? I'll be posting everything here throughout the process to seek comments and suggestions, and also so everyone else can benefit from the design. Don't try to flog them though, I just might sue
