DVD-CNC is still very much a project in progress. The purpose of this and the future posts in this series is to present project build notes which will, hopefully, help someone building a similar DIY laser cutting device. The project is not complete but some of the biggest issues have already become apparent. So, if you are interested in building your own DVD-CNC device, read these notes at least to avoid making the same mistakes. Besides, despite the project as a whole is still in progress, some parts of it, such as the TTL-controlled laser diode driver for example, are already at a workable stage and can be used in your own projects.

This project came about as a result of my propensity to never throw away parts that were designed to or can be adapted to move electrons. I am also very interested in mechatronics and motor control in general and so it was all but certain that over time I would have accumulated enough of various discarded data storage devices because they are so cleverly combining parts of both mechanics and electronics. We live in world filled with discarded devices that only a few years ago were the stuff of science fiction. I always feel bad about the discarded yesterday’s technology and it gives me an extra kick to have it re-purposed for today’s needs. Read the rest of this entry »
