Inside a Stackmat

I have the glow-in-the-dark stackmat and I took the back off to see if there was any way to put a port on it so that I could hook it up to my computer. I found a soldering spot in the bottom left corner that reads R27 and then a small hole beside it that reads DISPLAY. Is there a way to solder a jack to those points?

I also found another soldering hole that reads FREQ which i'm guessing stands for frequency. I have tried testing many different soldering points with a headphone jack with the headphones removed, leaving me with the wires on the other end (positive, negative, and ground) I got the timer to turn "on" on cct timer program, but I still couldn't get the timer to start and stop, it was only recognized by the computer. Can anyone help me further with this experiment/mod? I can post some pictures if needed.

I suggest looking at the stackmat pictures in Stefan's first post. In the second picture, the bottom left hand corner has the headphone jack. Notice how if you look at the first picture, in the bottom right (where the headphone jack is now) you see three wires? That's for left, right, and common/ground/neutral (whatever you prefer to call it). My guess is that the middle solder point is the common.

What do you mean by you got the timer to turn on?

Hmm while this thread is here, I'd like to ask about a problem with my stackmat:

The time and date is still displayed, and when I hit the power button the 0.00 comes out. But when I put my hands on the timer the display it goes 8:88.88 very briefly then goes off. Is it out of battery or something? I don't have a new battery that I can test it with =/

Yeah, that's the same symptoms mine had when it ran out of battery, and same with a few QJ timers I think. A new battery should fix it.

Most likely that is a low battery. You can use a meter to verify, but I suggest getting a new battery. That was to amos, I didn't realize there were so many posts ahead of mine.

cuberkid: Does the tamagachi stay on for a good bit? They might require less voltage to run than the stackmat timer.

Hrm, I'm guessing you know how the water got in there then. Did the issue start right after the water got in? If you look at Stefan's pictures though, it should be pretty clear how to open it if you really insist :p

The tamagotchi runs on much smaller voltage than the timer that has got LEDs (that are eating the battery, whithout them it would last for years instead of months). Water should not be a problem, when it drys everything is back to normal (if it was not salty water, then you may get problems).

sgosiaco, the competiton organiser have the timers you use in comp and yes, it is in the rules it must be a stackmat timer (fairness).

The buttons are crap, I have my power switch working in like 10% of the tries and the reset button I had to change for a new one because it was compleatly dead (my timer is about 5 years old and was used a lot the first years).

I did not do as Stefand but used a soldering iron and removed the old button compleatly.
