Mobile Phone
This is an old rotary dial land line phone where I pulled out original electronics out and replaced it with a custom made circuit board which I designed and made to turn it into a mobile phone (only does voice calls, would take way to long to send a text message with the rotary dial :) ). It uses the original electro-mechanical wringer which is nice (and loud).
Version one the main PCB I etched using acid an an iron on template for the tracks which is printed on special material in laser printer.
Version two I had a custom made PCB made which I designed
