Another Rotating Monitor Cab.
Richie Rich:
Been lurking here for years, finally started my own MAME cab.
I started by buying a gutted Simpson's cab about 2 years ago which needed allot of work but it's easier than starting from scratch.
The cab had nicks and chunks on it and someone put some texture type of paint on it so I sanded the paint off and used bondo on the nicks and chunks. Next came two coats of tinted primer and three coats of satin black rustoleum enamel paint applied on using a 6" fine foam roller.
Richie Rich:
Now for the most time consuming part "The Rotating Monitor"
I started with a 21" viewsonic G810 monitor and 4 X 8 sheet of particle board someone gave me. Then after many measurements I decided to go with the two disc method. I then uncased the monitor and after many more measurements cut out the two disc and rotating base for the monitor to spin on inside the cabinet. I then put the monitor in the two disc using short 2X4s to space the disc apart and added four 1" casters to the bottom of the inside disc to facilitate the rotation of the disc.
Now for putting all this in the cabinet and getting it to spin smooth with a motor.
The motor I decided on using is a winshield wiper motor from the junk yard. I mounted the motor under the base and bolted a 2 1/2 "caster wheell onto the shaft which goes through a hole in the base to the top where the monitor is. I bolted the base inside the cab and made a 2X4 frame to hold 2 1/2" casters to support the monitor assembley on the edge of the disc so it would rotate with the motor.
The rotating assembly moves nice when the motor is powered up!
So far so good.
Richie Rich:
Now I made an H-Bridge for the winshield motor. Motor now turns the monitor left or right depending on
H-Bridge input. I also have two limit switches installed at the top of the monitor area for controlling automatic rotation.
The computer I am using is a spare Pentium 3 running at 933 Mhz with Windows XP Pro SP1 stripped down and using MALA v1.05 as the Front End.
Next I will wire the parallel port and limit switches to control the H-Drive and control the monitor orientation using the MALA rotate plug-in.

Fantastic job so far, but dude, you got to change that avatar. It's disturbing :whap
Cornchip:
That's one scary avatar. Good choice of cabinets to start with. How wide is the opening?
