A few months ago I bought some hardware for interfacing my computer with the outside world along with a relay card and stepper motor card. I had some time over the weekend (actually I just couldn’t put it off any longer) to finish soldering the main board together and hook it up to the computer and table.

Back in November, during the PCGG-II gathering, several people spent a lot of time and effort trying to get a hologram out of the Liti Holographics material. After the gathering I put together a review and sent it off to Liti for comment. Continue reading “Litiholographics Kit”
It’s been a while since my last update and I’ve been busy copying various holograms and a few long business trips.
Ok, I’ll admit it, I’ve also been playing Half Life 2. Though not nearly as much as I’d like. Mainly the time when I’d be letting the table settle anyway.
At the moment I’m working on a new version of the PCGG-II hand-off hologram because I’m unhappy with the final results of the original. While elements of it worked well in a transmission, the contrast levels weren’t good for making reflection copies. As soon as I get the chance I’ll post some pictures of my latest work.
In the meantime, check out the Liti review I’ve just posted.
The release of Graham Saxby’s third edition of Practical Holography shows how well the author understands what people need from a complete book on holography.
He takes the reader through what a hologram is, the history of holography, what sort of light sources can be used to make a hologram, what kinds have been made to date and so on through to making and displaying your own images.
The book is written in a clear and concise manner and is augmented by additional tips, definitions, and observations in the margins as well as extensive source references at the end of each chapter.
If you’re new to the field or hobby of holography you should make this one of the first books you buy. Even if you’re an old hand this book will probably show you a few new tricks.
