Hello All

I am a product designer and electronic/computer tech enthusiast. I have experience in 3d cad, pcb design, programming for micros, mobile devices and websites. Repair is not such a strong suit though. I live in Brisbane Australia.

I'm not sure I will be able to help but need some help myself (yes that too)

Cheers

Christian
