However, I think that the real problem now is that currently if someone would make this device is forced to buy the same expensive TPMS kit that I've used in my project.
The best thing would be to make an agreement with the manufacturer in order to buy only the tire sensors and a receiver module ready to be applied on my hardware, or best, to entrust to him the whole build of the preassembled device. Certainly this would be more cheaper.
So if someone are interested in do this, is free to use my project, my only request is to leave me the sales of the PIC with the firmware inside.
Otherwise if someone is interested in self made it, I can sell to him the programed PIC.
why not make ask the seller of the tire pressure kit if there could be a lower price if we buy more at a time? i think there would be enough people who want it to get a nice reduction... maybe you could make a poll? you bought the kit for 200 euro? and i have no idea how much the other parts cost you need to modify the kit, but maybe you could somehow make a complete kit, ready to connect and sell it for 250 euro? or maybe less, i don't know?
so, maybe when you get a price from the seller, you could add your own parts and work to it, make a poll, and see how many people are willing to pay it...
sorry for the italian but I can't esprimere tutta la mia ammirazione in inglese....il tuo lavoro č FANTASTICO!!...Complimenti veramente, se riesco ad avere un kit sarņ il primo ad acquistare il tuoi pic...Complimenti ancora!!
Who is the manufacturer?..someone can contact it?...my english is worse.
If we could obtain the tire sensors and a receiver module as robby said....
I have sent Robby a PM ...im sure he has been getting plenty about this!!
I might be able to sort out getting just the sensors from a manufacturer... I used to work at a F1 company and have some contacts.
I have been wanting to get this into developement for years but never had the opportunity!
By contacting the manufaturer's/suppliers and getting just the sensor's, Im sure i could knock up a seperate PCB board that controls it and is a straight RF-USB converter so that would illiminate the need to buy a whole kit and "hack it up".
Just an idea mind.... id be willing top take some of the developement of this (as having previous experience)
Added more photos and description in the first post.
Looking real promising Robby.
