Hi all, I'm new here and just became the owner of a possibly useful JHE beam table laser projector. I say possibly useful because I'm sure some of the parts are missing and some broken so I need to find out what they are to get this system up and working. I was happy to see that both lasers came up and are working. I must admit that I didn't think the green one was any good as it took a few minutes to ignite. Perhaps that is something that will need work later.
First thing that I need to find is a power supply for the driver cards. It kind of looks like a simple computer supply would plug right in. Before I start tracing wires and guessing as to what the power requirements are, I thought that maybe one of you fine people might know or have schematics of this unit and help me get through.
There are four cards labeled LSDC with a logo of AGCD (I believe) with a number of 53005. If anyone has any idea of who the manufacturer is perhaps I could find some information on the web. There are four cards: one for X, one for Y, one for red blanking, and the last one for green blanking. They all appear identical at first glance.
There is also one mirror missing. I'm not at all sure, but it looks like it need to be of the half silvered variety. It looks like the green laser is reflected around to the back of this missing mirror and then in to the reflecting servo mirrors. The red laser would appear to reflect off the front and then into the same mirror.
The programs are on ADAT 8 track tapes. I believe four tracks for the audio program and four that run a controller box which then feed the the four cards.
I am in the process of building a planetarium to which I believe this would be a nice addition. If anyone can help me get this system working properly again I would be most appreciative.
