USB adaptor for Amiga Joysticks
Hi guys!
as the title says, I would like to build an adaptor that converts the DB9 port to an USB in order to use the good old amiga joysticks. I've found this thread which is very very relevant to this purpose but it seems to me that it is a little bit old therefore I decided to start a new one (hope that it is a good choice). The aforementioned thread gave me a lot of precious information and ideas but there are still some points that are not clear to me. In particular, being a beginner, I would like to ask you what GND (ground) exactly is, which is the function of the GND wire and how I can recognize the right area in a PCB that I should use to solder the GND wire. Furthermore my objective is to build an adapter for the Albatros joystick (a popular joystick built for Amiga) and that joystick had two buttons that made the same thing. Should I solder two wires (button1 and button2) on the same place of the PCB or it is sufficient to solder only one wire that (maybe?) controls both the buttons? Eventually I have some questions that are expressed in this image http://img809.imageshack.us/f/14747660.png/ thank you very much in advance! Last edited by Nono Nano; 15 April 2011 at 02:10.

Erm, to do what? Buttons are switches, they have three terminals and if you want to "extract" the state of the switch you solder to two of them. (Maybe one depending on your design) I'm sure it is lots of places. Why does it matter that GND is there? |
