What I do not understand is why there is not a simple, get these pieces fo hardware, do this step by step, and this software works, it seems a tough struggle, can anyone provide this?
12.3" display
KHADAS SBC
Can Hi Lo adapter.
what else do we need to get one of these up & running?
You have the right mix of parts, so far. The real issue is, and has been power management. It will run, but will it turn on and off properly? Will it boot quickly? That seems to be the issue. If someone would offer a SBC solution that would run RD and both wake up quickly (and reliably) and not suck the main battery down when the car is not running, they will have a real product on their hands.
I’m told somewhere on this forum, there is a solution that meets these criteria, I’ve been looking to an hour now to find the thread…
hardware demonstration thread, post titled UIS7862
I’m am also about to have an alpha unit for testing that I’ve tried to do this. I’m using a SBC type device that is running RD and an external controller to handle the sleep/wake-up and power functions of the SBC. My main goal is that it sleeps the SBC when the car is turned off for a near instant wake-up, but also monitors the power of the car and if it gets low will actually shut down the SBC. I’m also going to have some other triggers to start the SBC up if it’s powered off to help the perceived boot up time.
Currently we are pushing this towards a specific car make and model, but we are also going to do universal units and units that can be customized.
Very much looking forward to what you come up with!
This seems silly and kind of ‘caveman’ compared to all these detailed solutions…
But I just bought a used HP mini desktop with an I5 quad core and 16gb of ram, a 13.3" monito for the actual dash, and a 12v to 120 AC converter. The monitor power runs off usb from the computer, and the computer is in an S0 state to where it turns on after power loss (key off, in my case; key on being ‘power on’). Obviously, RD is set to resume or stop depending on ‘charging event’.
PC to converter, converter wired to key-on/key-off power. OBD@ to USB makes it all seamless.
In all, it takes 15 seconds to get RD up and running after I turn my car on, and I have the power and functionality of a PC in my car. I’ll be running a separate touchscreen as an extended monitor that ill install in my radio bezel so I can have navigation and everything flawlessly integrated. Im installing a 4 port USB hub in a semi-discreet location for controllers, usb sticks, and whatever else I want or need to use with said computer.
All in all, my startup time is only limited by how fast I can get my PC to load on key-on… and since I always wait until my RPMs drop to sub-800 before driving off, I barely have time to get situated (belt on, drink in cup holder, adjusting radio) before THAT even happens, so it works great! Cost me less than 300 bucks all told.
However, I don’t have all functionality (headlights, blinkers etc) but did find a solution or that as well.
Regardless, while there are some amazingly technical solutions out there, RD can be implemented using far more basic methods, too.
Did you get an OBDII feed?
I would be interested to know how you got turn signals, PM please
