You'll have to be a bit more patient. Not everyone's living in the Romanian timezone...

I checked the website, and this looks like a really interesting project. One that I would probably build myself... once I get a car that will actually output OBDII diagnostics info :lol:

However, since this is a commercial product, your best bet is probably to buy it. It looks like you can buy the PCB only... Sounds like a good and cheap way to tinker with the circuit.

I understand that, but have you checked the prices? **broken link removed**, which is less than $13US for the bare PCB... You can still supply your own low-cost parts and build one very cheaply. I can't imagine making your own PCB costing much less than that?...
