Pachinko
by gipsy on Sep.12, 2010, under Nishijin, Pachinko
Well, almost exactly one year since my last post …
Simply neiter had time to work on my projects nor really felt like it. But now the fever is back 
But of course I started something new instead of finishing one of my other machines:
Last week I “accidently” got a Nichijin Pachinko machine in almost perfect working order, only missing the payout ball tray and the card bypass dongle.
Luckily I had all the tools at home to finish these parts, the ball tray is cut out of an old emergency exit light.
Now it’s nicely mounted on a wall in my living room.
Next will be to add a ball lifter to it for more playing fun, I’m thinking about building one myself either with a flipper coil or with an old jigsaw I have lying around … we’ll see how it turns out (if ever )
Sorry for the crappy images, but the HTC Hero is a nice tool for almost everything other than using it as a camera ;(
Gigantor Wiring -> SCART
by gipsy on Sep.10, 2009, under Arcade, Gigantor
Since starting the Gigantor Project I destroyed 2 of my 2 Hantarex Arcade monitors 
I was searching on ebay and other platforms, but didn’t find any Arcade monitors for sale, so I decided to add a SCART output to my Gigantor wiring to use an old and cheap TV as monitor.
Today I finished all the wiring for the Gigantor, I want to be able to use JAMMA and other PCBs so I decided to go with the Austrian “Novomatic” 50pin D-SUB as my main connector. I believe this should be the most durable type.
The finished wiring consists of one primary female 50pin D-SUB which can be connected to different PCBs via (still to do) converters. From this there are 4 main connecions:
- Video: 15pin male D-SUB connector wired according to the VGA standard
- Audio: Stereo female TRS connector
- Controlers: 38pin female Centronics connector with own pin assignment
- Mains: 9pin Connector to Hantarex US200
On the Video part follows a SCART connector which also needs +5V for switching the TV to RGB mode which is routed via Chinch connectors.
Today was the first test and YEAHHH … everything works perfectly … playing Arcade games on a 42″ Full HD rulez
Everything is wired in a way to replace any part at any time, for example it’s no problem to replace the SCART connector with an Arcade monitor connector, or completely replace the PCBs with a MAME computer.
At the moment I have no camera, but I will post some pictures at a later time.
New project: Gigantor
by gipsy on Aug.14, 2009, under Arcade, Gigantor
Yeah, I know I seem to be unable to finish one project before starting the next one
Nevertheless I did it again. Since I bought together with a friend about 40 original arcade PCBs, I thought I’d need something to put them inside.
First I wanted to use one of my existing cabinets for this, but soon I realized I’d need something special because of 4 different connection systems (5 if you also count the MAME PC), portrait and landscape monitor setting and different controls layout and other ideas.
I really liked the “monumental” design of this case, but I was missing some of the more traditional elements, so I fired up my trusty ARCHline and modelled my own case.
It’s fairly big so a midsized monitor can be turned from portrait to landscape inside the case (I plan to make it motorized )
Contrary to the rendering I’ve changed the color scheme. While blue is my favorite color I decided to go with some kind of purple for the base and a nice grey for the top.
Some first work is already done on the case:
Convert Operation Bear to Mame cabinet
by gipsy on Feb.15, 2009, under Arcade, MAME, Operation Bear
The last days I was working a lot to convert the Operation Bear into a general MAME cabinet.
As always I had more or less no plan what I was doing and just learned by doing.
First I destroyed an old PS/2 keyboard and soldered the arcade controllers to the keyboard controller. The Caps/Num/Scroll Lock LEDs are used as CPU Load indicator (25%/50%/75%).
Then I checked how to connect the Arcade Monitor (Hantarex MTC9000) to the computer and decided to solder a VGA connector directly to the Monitor Input. In this way I can hook up the computer with a standard VGA cable and simply switch to the original Operation Bear by plugging out the PC and plugging in the original ROM.

All the computerparts are mounted on a piece of wood which perfectly fits into the cabinet. I also bought some new low cost speakers, dismantled them and mounted them into the original places.

The next step was to mount the controller assembly into the cabinet without destroying it. Everything should be completely removable so the original lightgun can be mounted again.
The last missing step is to put some nice finishing over all my naked wood parts, but this is again something I have to learn
