After several days of tests I’ve gotten a couple of decent transmission holograms on VRP-M using a Coherent 315m.
You ever look back at something you did months ago and wonder, "why did I do that?"
I did that this evening with the controller that I’ve got in my lab.
I’m starting work on another hologram for a professor at A&M and needed to do a bit of maintenance on the table. Strange, but every time a new hologram request from her comes in, there’s something that needs doing in the lab before I can get started.
This time the HEPA fan wasn’t shutting off during an exposure and the table light sensor wasn’t working.
It turned out with the HEPA fan that somehow I’d wired up the relay connection with an additional 5v going to it. I have no idea why I did that. Fortunately it just caused the controller chip on that port to heat up (and not work) but didn’t blow anything. Odd that it was working for a while and then just stopped.
The light sensor just turned out to be a loose connection at the junction between the table wiring and the controller wiring. Gremlins.
I also found a problem with the holocontroller software not always shutting off the fan and fixed that.
Now I just need to straighten up the lab, prep some film, paint the subject and shoot. All tomorrow morning.
I’ve added 10 of Lon Moore’s photopolymer holograms to the store which are available for immediate purchase. These holograms were originally created for his Red Beam line and several have become collectible items.
The holograms include:
The original Enterprise from Star Trek
For the latest Holography Forum contest I made a hologram of Snoopy and Woodstock.
I’d originally planned for the final hologram to be a bit different but I’m happy with what I’ve got.
Read on for the making of Friends.
A few weeks ago I started work on a hologram inpired by Pirates of the Caribbean and began carving a medallion that I wanted to look like the medallion featured in the movie. Unfortunately my sculpting skills aren’t yet up to that task but I was able to produce a medallion that is more appropriate for a Day of the Dead celebration and set about making a hologram of that.
The big project this week was a new version of the US flag hologram I made for Andres when he became a US citizen.
I’ve wanted to add fireworks for some time now and started work on just that last weekend.
This tutorial assumes you have full control of the hologram and can take it off the wall at will. If you’re trying to take a picture of a hologram that’s permanently mounted to a wall or one where the owner won’t allow you to move it, you’ll need to adjust accordingly.
