Or, for that matter, post them here, as this is a feature request thread

Ability to control a few relays after computer has turned on. So delay for screen and amp.

The plan is to have the SDC expandable.

due to the apparent size constraints on the SDC board, there's barely room for an 18-pin PIC, so the number of onboard I/O is limited. Thus far, onboard, in addition to the typical connections for power control, I have placed a temp sensor, some status LEDs, serial lines, and analog voltage measurement to monitor the input voltage. This board will have any settings (like all the delays, thresholds for voltage/temp warnings, etc) configurable by serial.

So there's not really any more room on the SDC board for more stuff. HOWEVER...

the plan is to have an external addon board (this is where the expandable part comes in) that connects to the SDC via a 4-pin connector. since this board doesn't need to be inside the PSU, it can have as much on it as needed. This is where all the "fun stuff" will go... things like various temp and voltage monitors, relay controls, extra status LEDs and control buttons, serial communication with the computer, etc. etc.

The reasoning being that this allows a SDC with moderate features (all the important stuff for an SDC to do, and comparable to the built-in SDC's of other PSU's) to be in the PSU, and anyone who wants more control or features can get the expansion board.

Oh, is the SDC gonna have a serial port? If it will, it woudl be cool to have it send the car's battery voltage

The expandable part sounds good

yes, it is. And yes, it will be able to send car voltage readings, as well as the temp reading.

I plan to make it so that standalone, the SDC will output that kind of info repeatedly, and accept commands from the computer to change the above mentioned settings.

When connected to the expansion board, both the computer and the SDC will communicate with the expansion board, allowing access to information of whatever peripherals are on there.

I sent a pm to dragonBTV. evandude, I would prefer to talk about my ideas over pm if that is ok. I will send you a pm later today sometime.

you can say anything here instead of PM.

I am an open one

due to the limited space,
I will leave a stand up or flat over head space for the SDC board, there will be a 14pin connection.

the function of 14pin will be released here soon. (fan control should be inclueded in SDC)

green LED3
kill fans
fan yellow output(the speed control yellow line of fan)
temp sensor(should tell me the detail of the sensor IC or R)
