    Hi mermaldad,

    What part are you interested in?

    I have 85% of the startup / shutdown controller complete. It is a USB programmable controller which once connected is controlled by a software frontend. So you set the parameters of the controller via the software and once thgey are sent to the controller it uses these throughout. That way it is also very easy to change the settings. There is also one other VERY cool feature which i have never seen else where on these controllers which i will keep sectret until its release !!

    If it is the Relay Controller, then not no hardware has been done on this yet. However, the work i have put into the SuSd Controller can be very easily changed to make a USB relay controller.

    Do you have something particular in mind?

    Regards,

    Steve

    Sounds nice, Tissy. I would say that's really the best way to go and I don't think anyone could go back once they use something integrated like that. If it's like mine, you have the SD timer controlled by software, which alone is wonderful to have because it doesn't need to assume you want to shut down because the key is turned off or whatever, plus you can be a lot more creative with all the extras.

    It is kind of Software controlled, its software which send the timing functions to the microprocessor. Its then the microprocessor which sotres these timing functions in EEPROM to use when required.

    You are right, as its is microprocessor controlled, i have set various methods to signal the startup or shutdown routine, all selectable of course.

    So you could have it one day shuting down when the ignition is turned off, or the next day have it shutting down when the vehicles alarm is activated. You just need to change the settings in the software front end and then these setting are sent to the microprocessor via USB.

    I'm sure the full device will be posted here once complete.

    Ah, I understand. Same way here. The SDC send events to the software for ACC change etc. and starts the timer, or the other way allows the software to start the shutdown or standby timer or just sit and heartbeat it if the user wants to continue for some time. You can make it very interactive and flexible and still failsafe.

    What I'm after

    Actually my interest stems from a project I'm working on to teach students about robotics. I'm looking for a way to control a R/C vehicle from a PC. The transmitter uses switches to control the vehicle (i.e. it's not continuous), so a set of relay closures should do the trick.

    The way I did mine is like this >>>

    A small SDC apps run on the PC taskbar. When the SDC HW detect the IGN going off, SDC send a signal to the PC, to the SDC apps.

    SDC apps then pops up and give the user some option. User can then select the amount of time before the PC shuts down. The user can cycle through 5mins > 10mins > 30mins...> infinite. The apps default at let say 15mins, the SDC apps then send the shutdown time to the SDC HW once the user has selected the required time. In the event of the PC crashing and not able to send the user selected parameters, the SDC HW then use the default time.

    Of course you have the heartbeat monitor on top of that and the usual SDC function like low voltage, temps...

    Theres alot more to it but I cant really mention it here as the project is most likely going commercial...sorry guys

    Cool! Almost the same, but I just hit the standby or stay on, configured times, or in 10 seconds it hibernates. No low voltage or temps though. I used up all the other pins for extra relays, SWC, IR, radar detector and stuff. Well, I think a lot of users would buy something like that. It's so much nicer than anything else yet. Oh, I also use the pulse/remote/button thing a lot. Just hit a button to power on without the key in. It starts with my remote start too. There's a lot more that can be done here though and hope it becomes the standard eventually.

    Is this project still alive?
