Prisma Puzzle Timer

By default, the gen3 timers emit a gen2 signal. The gen3 displays will have some way of telling the gen3 timers that they're plugged into a gen3 display, and only then will the signal emitted by the gen3 timer include the thousandths place.

I'm hopeful that we can come up with some way of simulating whatever the gen3 displays will do that we can get thousandths place digits when plugging the stackmat into our computers. I'm not much of an EE guy, but I'm fear this won't be doable with only the line in jack of a computer's sound card. I suspect we'll need to split off the left or right audio from the cable and run a special voltage across it in order to coerce the timer into emitting a gen3 signal.

What I took from this thread was that the gen3 timer wasn't working at all with Prisma, or is that not the case? If the gen3 by default emits a gen2 signal, it /should/ work perfectly with the current computer timers

I'll give a proper explanation later, but any experiencing trouble should make sure their stackmat is plugged into their computer before turning the stackmat on. If they've already plugged it in and ppt or cct isn't working, try turning the stackmat off and back on again. Sorry for the voodoo, I'll try to get an explanation up this weekend.

no It doesn't work at all.
 
I don't want to turn this thread into a discussion about timers, but since Dan is here I suppose he can speak up if we get too distracted.


Ok well I guess I was wrong. I'm wondering how the displays still work with the new timers though... Does anyone want to record a few seconds of the output so that I could analyze it and compare to the old signal?

Gen 3 Audio
Recorded via mic input with no microphone boost and input volume set to 90%, times are approximate.
The file starts with the timer being turned on.
0:00 - 0:05 | Timer is idle
0:05 - 0:10 | Palms on timer
0:10 - 0:15 | Timer running
0:15 | Timer stopped

Are you certain this is how it is done? I suspect the gen 3 timers include the extra digit at all times, but that they current displays ignore the extra data because they are not programmed to use it. I understand that the packets are only 8-bit and that all 8 bits are already utilized by the current displays, but perhaps they have gotten creative.

I have the following problem:

My stackmat is connected to the PPT and it works. But about every 10th solve the timer(PPT) starts timing while I'm scrambling. But it keeps timing under one second(00.00 to 00.40 to 00.00 to 00.24)(I hope you understand) and I just can stop this if I put my hands on the stackmat but then it adds 00.00 to my times and I have to delete them manually.

Are you plugged into the mic or line in jack? If using the mic, try disabling "microphone boost" under playback settings.
 
how do I start the timer w/out a stackmat? I have it set for the control keys, but no matter how I press them, how long I hold them down, etc, nothing works. I tried setting it for spacebar, but I couldn't get that either. I'm on windows 7 if that changes anything.
PS, I do NOT have a gen2 stackmat with a dataport.

EDIT:: I got it. I just had to restart the program a few times.

I've been using prisma timer .4 for about two year and its been working fine until today.

I seem to get a Database error whenever I open the application:
General error: "java.lang.ArrayIndexOutOfBoundsException: 0" [50000-137]

I cannot access any history or previous times/scrambles.
Can someohe help?
