MAME Arcade Machine

Here's another project I'm working on.  A year ago or so, my brother mentioned something that sounded interesting.  He was thinking of making a game cabinet to hook up an old gaming system and controls he had so that it would be like an arcade machine.  I got to thinking about it and thought it would be cool to set up something with all the old arcade games that I played as a kid.  Turns out people are already doing that with arcade machine emulators.  Ive set up an old PC to be the emulator and purchased an old arcade machine for $65.

Here's the cabinet:

Interesting thing is that it works just fine.  I plan to gut it and put the pc, monitor and controls in to it.

Here's the inside:




Even found a few bucks and tokens inside it!

Rear Projection TV

About two weeks ago, I bought a 55" Philips rear projection TV (DPTV340) off Craigslist.  The idea here is that I can drop $100 bucks on an older TV but can't drop $900 on the projector I ultimately want to get for my basement.  The snow is flying and the kids are inside most of the time now.  This, along with the other games I've collected over the last few months, should keep us well entertained during the winter.

When I got the TV, there was a blue shadow around everything on the picture.  In addition, it was very dim.  A little research told me that this type of TV has coolant as an optical coupler between the CRT and projection lens.  Apparently, it's common for that coolant to get cloudy and need changed.  I went to a local electronics store and picked up some coolant for around $25 and went to work.  After cleaning everything up and changing the coolant, it looks like a new TV.  Not bad for $125...






The coolant should be completely clear.  You can see what the old coolant looked like from the green and blue lenses.  The red one was fairly clear.  In fact, I needed to reuse some of it.
