I will check today the keyboard with the tester and report what is happening.
The controller is connected to the barrels board using a screw. This is contact with the case. It could be that this is not sufficient. The tester will tell us.

My guess is that it is plenty sufficient. If the case was not grounded correctly, you wouldn't get shocks. You get them because you get discharged through the
case to the cable, to the psu, to electrical earth.

All,
I have changed the entries on the pool for you to vote.
I am typing with the finished keyboard that I will open again to show you the pictures.
There are news, errors, patches, and recommendations to come with regards to the xwhatsit controller. I broke and repaired one of my keyboards ! I will try to post some more information today.

As far as the voting goes, will there be anything like an elimination round? To take the names that have no votes out and then have everyone vote on the highest voted names?

Very clever way of fixing the broken xwhatsit controller! How did you manage to find out which cable goes where? Was everything documented in the xwhatsit manual? Anyhow, it's really impressive what you did. Others would have simply given up and bought a new controller.

Good idea. I will eliminate the options that are not voted or with 1 vote after Wednesday !Redmaus wrote: ↑As far as the voting goes, will there be anything like an elimination round? To take the names that have no votes out and then have everyone vote on the highest voted names?

Finding where to get the cables was not really complicated. I could have asked, but reverse engineering is fun:
1.- Get the usb pinout. For instance.

2.- Get the PCB layout

3.- Get the pinout of the atmel. This will help to find out the resistors from the other side

Figure 1-1. Pinout
The rest is a matter of testing the resistance between the pins.

Great detective work! I hope no one else gets in this sort of situation, but your approach shows that there is a fix to this mistake. Thanks for the insight!idollar wrote: ↑ Finding where to get the cables was not really complicated. I could have asked, but reverse engineering is fun:
