Long time no update

Well I left my camera with my parents, so I've been unable to make some pictures and movies on the progress. Which eventually makes it less interesting to update.

But I've become further, the setup which you've seen underneath, has been a little modified. The 25V AC made the signal of 5V to my computer vibrate at 100hz. This wasn't very useful for my computer to understand what was happening. So I needed to build a more complex circuit with condensators and rectifiers to make things happen. Also I reconnected most of the relais from the 25v AC to 5V DC from my wiring interface. Only the parts that work with coils did I leave on the 25V AC.

I've constructed the most beautiful multicables, which themselves need to be photographed. And by now I've got every single target talking to the computer as an indivdual. Not flawless though, I receive the input from the coils somewhat in a ratio of 23 against 30. But I'm working on it.

Today is to try to decapitize the pinball machine. Made a start yesterday, disconnected 40 from the 50 wires. But those 10 are essenstial, I hope I'm able to shortcircuit them all.

That's it for now, I should try to recover the camera and make so new footage.

It's ALIVEEE!

Well almost, by now it's more like christmas in my pinball machine







Dr. Frankenstein would be proud!

Pinball machine says: Hello World!

Watch it here
Thanks to the help from Arrens

Small breakthrough!

I finally converted 25v to 0,7v computer friendly input!

0,7 volt is currently too less, it has to be 2,5v or plus, but from here we can start talking!

Tuesday

On Tuesday I went to visit flipperwinkel.nl in Arnhem. I bought several things, new rubbers, wax, a new ball, new flippers, and new flipper coils. I didn't need to replace my counter mechanism. I've been told that it used to work in that fashion. So I guess I'm the noob around here.

The installation of all the new materials was quickly done, except for the coils. It took some time to install and adjust the coils to the right settings. But on Wednesday I got both coils working and thus the Pinball machine.





And here's a movie of the flipper up and running (you should turn your head 90 degrees)

Monday

So on Monday I wanted to try to make the Pinball speak to the Computer via a Wiring USB interface. The Pinball target circuit puts out 25V versus the interface which only can hold a mere 5V max. With my basic knowledge of physics I figured I needed some resistors to do the job. When I went to get some the people at the shop stongly advised me not to build this circuit. The induction build up in the resistor after could eventually and most probably blow my Wiring interface. They advised me to use opto-couplers. These opto couplers would isolate my interface in the circuit from being damaged.

So I tried a few set ups, did not yet find a working one, but I'm working on it.

The Concept in global (and dutch)

For those who are able to read dutch and want to know more about the concept, the global version is to be found here.
