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.
…i’ve been surfing the internet with a furious passion and trying to do little projects whenever possible. Here i wired up two uln2003a stepper motor drivers onto perf board. I’m not sure what i’ll need it for, but I’m pretty sure i’ll need it!
