Thanks for the suggestion but I feel an Arduino would be wasted here.I used one in my last car because I thought it was kinda cool to tell everyone I was using an Arduino in my car,hoping I could finds lots of cool things to do with it.But because of my inability to write code and the Arduino forums being the least helpful place in the world,all I could ever get it to do was to control the headlights,which thinking about it afterwards was a lot effort with not much to show for it.There is voltage on various points inside the Joggler that is only there when it's switched on,so I could use one of these points to drive a simple transistor and relay combo that would disable the ability to remove the power feed from it until it's fully switched itself off. this would avoid the need for manually doing this and the issue of sudden power loss to the joggler causing corruption. Someone else will know whether it is possible for the Arduino to send a shutdown command to the joggler and then wait for some indication that this has occurred (eg no power on USB out of Joggler) before shutting off power to the joggler.

You can fix the Joggler USB stick corruption by using an SSD USB stick which works way better for the Joggler or the integrated PATA port with an SSD drive on it. On the USB side of things an independant carpc USB powered hub which works exactly the same as above except the USB 5VDC gets it power from the car and not the Joggler.
You could utilize this with any car pc such that if you decided to swap out the Joggler it will work with another car pc. There is also a timing circuit on the picopsu to cut the power in XX seconds no matter what such that the battery doesn't get drained. The joggler shuts down in a timely manner. When you shut off the car the picopsu sends a command via USB to shutdown. So connectivity just for the power on the Joggler would be:Ģ - USB to Joggler just utilized for shutdown You can also add a UPS board (tiny thing) to enable a bit more shutdown time. The only part that doesn't work and will not work with the Joggler is the tickle to turn on the Joggler which you can bypass. It has a built in USB output which the computer can control. One that goes to the main battery and one that goes to the aux ignition on. The intelligent PSU get's two 12VDC inputs. I am doing this today with an intelligent pico PSU.Īs suggested earlier you shouldn't use the Joggler internal 5VDC and separate that piece out. This is a smaller footprint than the Joggler and could work in your setup providing you with digital outputs and a basic touchscreen interface. Yup you don't need to add an Arduino to the mix.Ī while ago played with a Pogoplug / Mimo monitor and it worked just fine.
