My newest project involves reincarnating a very old (1998) cd duplicating robot. It is a DTP-1000 that was originally SCSI only. Due to the fates smiling down upon me I was able to pick it up on ebay for $11. I bought it intending to put an arduino in the place of the control board and probably have to do a lot of reverse engineering. The next day I happened upon this site where, amazingly someone has already opened one of these up and has instructions on how to enable serial control! I still am in awe of how lucky I got and really happy that DarkBane dropped all of that knowledge on the world.
There are a lot of pics below, since that was the one thing I could do to add to the fine directions DarkBane has already provided. Another thing is that in his command set he has two typos. I will quote his post after the pix and note the command set in bold.
Check out my new(er) cd robot project here. I grabbed an old scsi changer machine from ebay and have been working on adding serial connectivity to it. If it works, it will be a much simpler route!
One of my “always in my head” projects is a CD changing machine. I have seen the myriad of otherprojects out there, and this always captivates me, in that it is just out of reach, but it seems to be a fairly simple concept. I have been thinking and sketching on this one for SUCH a long time that I have decided to post it before it is fully polished up.
The basic premise is I have an arm that swings up and down mounted on a platform that rotates 180 degrees. Both of those are positioned by hobby servos. On the tip of the arm there is two vacuum aided suction cups and some hdpe tubing.
