Thread: Anyone interested in serial controlled Relay/Input card?

Also see my other thread about posting PCBexpress files or similar... be nice to be able to order three of these up and have 'em overnighted from the fab shop =)

Wow, this would be awesome if you pulled this off. This piece, a carputer, and a nice 2-way alarm could give you just amazing functionality. I'm already envisioning just amazing communication potential between the electronics in your car. Trunk pop, factory alarm arm/disarm, keyless, window/sunroof roll up or down, power antenna, factory amplified antennas, and the list goes on. I want one!

Yup Ill keep you guys updated for sure, I have already looked a bit more into it.

I have already got one person in the forum to do the windows software for it, hopefuly he wont back down...you never know.


As I said I dont have the knowledge or the resource to do those windows program. Who else is willing to program a windows software to control it? I cant continue with the project if no software will support it. Heck I dont even really need one, Im just doing this out of interest and to help the community.





Also see my other thread about posting PCBexpress files or similar...

I only got access to protel, so Ill design the PCB on that. The PCB is not gonna be that complicated so it can easily be redrawn in another PCB software.

UPDATE :


Ill be using the main following components :
PIC16F73 : Microcontroller
ULN2803A : Octal Darlington Driver Arrays
MAX232CPE : RS-232 Transmitter/Receiver
7805 : 5V Voltage Regulator


Specifications :
8 Relays
8 Digital inputs
4 Analog inputs


Possible Applications :
RELAY :
CarPC controlled door lock, windows, boot, antenna, amps...etc

DIGITAL INPUTS :
Handbrake off indicator (Disable movies/vis playback),
Reverse indicator (Used to turn the rear view cam on),
Seatbelt, opened door, opened boot...etc

ANALOG INPUTS :
Distance indicator (Used for parking),
Car battery voltage monitor,
Backup battery voltage monitor,
CarPC temperature monitor...etc

Im coding the PIC right now and most of the code is working on my "test PIC". Will be buying the real parts soon and see it real

What exactly would you do with this?

This relay system just says (for example: "yes, your door is unlocked" or *unlocks your door for you*)

I want a trunk popper but I think I'll end up going with a relay through an alarm system... unless this does that somehow.

Hey Ricky We will add support im currently coding support for a slightly different relay card that has 72 i/o combination of Analogue and Digital inputs all low current sourcing so external realys are needed but its conncet via RS232 and i have Visual Basic Libs for it, but would love to add support for the card in AIMEE.
Let me know of Complete command set and we will add it
p.s hows the GPS tracker and Shutdown controller coming along?
Have been considering intergrating a shutdown controller into aimee aswell possibly USB connection.

WOW 72 I/O isnt that abit overkill?

Seems like you have a very interesting project there. Sure Ill give you the complete command set...Im still tweaking it though.



The tracking device...well its working as it is. The hardware hasnt been finalised yet though. I have added a sampled voice stored in EEPROM so on calling the tracking phone it will anounce the location of the car. Its working but I still need to put all the pieces together.

The shutdown controller, the hardware is all done, PCB and all. Theres code in the PIC which im not too happy about. In the meant time I have put that on hold.


Your are based in UK? Ill send you a sample of the relay card when Im all done.


Thanks for the support.

Have you got the link or info about this 72 I/O card?

I need to find out more whats the best way to get the digital and analog inputs. Like the input sensitivity of the analog inputs. And the pull-up/pull-down of the digital inputs...I may also set the trigger voltage at 6V. The relay card Im working on should work with standard car relays up to 40A and are to be placed offboard as adons.

Ill love to get all this done on USB in the future.

Count me in for one when u get it working and thanks for doing this for the community I know I really appreciate all that everyone does around here
