Squeegeeing

The topic of film squeegeeing comes up fairly regularly on the holography forum and I’ve been meaning to write up a method that I use with good success.

Read on for more info…

I am fully operational Sir

The board and software now have everything I need (the rest is a bit fluffy) which includes:
1) Software control of both lasers (although I still need to hook the AC relay board to the 33mW laser).
2) Software switches for the lasers and shutters.
3) Basic light sensors that can check to make sure the shutter opened.
4) Status lights for when a laser is on and when an exposure is in-progress (IE, the shutter is open and film is being exposed).

Some shots of the board follow.

Sourceforge project open

The controller software has come far enough along that I’ve opened up a sourceforge account for it and will start accepting other developers that want to help out with the project.

It’s officially open-source at this point and is being released under the GPL license.

It’s alive! Again

The controller software is fully functional again and I can get back to making holograms while continuing to upgrade the hardware and software.

Shown to the left is the board hooked up to two shutters and a light sensor. The lit LED is showing that the light sensor is seeing enough light to activate the input channel.

I’m now going to start the process of opening a sourceforge account and getting the controller software set up under an open-source license.

After I clean my office. It’s a disaster (again).

Computer Control for the Table

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.

New store in the works

We’re working on a new store, featuring holograms and perhaps some gift cards. What do you think?

New format

I’ve been wanting to move to a blog format for some time. Keeping all the web pages in sync is a pita and automating it made sense.

Bink! the fish.

I had to rush to finish it but I managed to create a master and two copies of a new hologram in one morning. I wanted to make a special hologram for Susan based on a game that we played (and she mastered) on our last trip to Jamaica.

Litiholographics Kit

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.

Musings & review

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.
