I only have experience with one type of game pad controller with Chronocone -- and it was a cheap one.

I did build a front-end interface circuit to take some of the noise out of directly connecting long wires to the contacts in the gamepad. It consists of opto-isolators that take the tape switch contacts to turn on the LED, and the detectors then go to some transistors to switch across the contacts of the game pad inputs.

I should tell you that most modern slalom skateboard races today use the Trackmate hardware coupled with Marcus Seyfarth's "Excelmate" software. This is the most reliable, easy-to-use setup.

We still occassionally use our Chronocone for some events that don't use the standardized spreadsheets.....

Thanks for that, never thought of trying an opto couple, and when I started I had hoped that the gamepad would be enough to get us up and running. Would you be able to send to me your circuit diagram via, please?

It is interesting that the other gamepad buttons seem quite de-sensitised to the interference, which is why I was hoping to be able to reconfigure the program to pick up the other buttons to test it out. (which begs another much harder to ask question, cause I suspect that it involves the source code) Can it be re-configured by me?

We do have an early model trackmate down here for when we all get together, with Colin Beck, but that is in Sydney, and I don't think that it has the data interface, and we are trying to grow the sport on a very small budget, so for now a new trackmate is a bit out of reach, and Chroncone simply makes more sense!

Got Chronocone hardware working OK.
Thanks for all your support.

New USB interface for Chronocone!

See ... SwsN9XAhvr

It is a module for arcade style game consoles, and is so much easier to use than game-pads, because the switch connectors are human size.
It also seems to be a lot more reliable than the game-pads.

Testing so far looks like Opto-isolator is not needed, because it is built for those big buttons on arcade machines.

Cheers again Pat!
