V2.0 complete...
Well on Saturday I was able to complete the 2.0 version of the DJ stand. It is extremely large in comparison to V1.0, which may limit its usefullness. I have also decided that in the future, I will purchase a pre-made stand and touch surface from PeauProductions. Costwise and pain in the ass-wise... it seems a better choice considering its fully adjustable in an aluminum frame. I will also be picking up a short throw projector and selling this pico so that I have better luminosity and a shorter throw. Ill post up pics tomorrow... maybe a video as well.

Version 2.0
So after using the first iteration of the table... I found many weaknesses in the design. For one, the table wasnt as sturdy as I had hoped. The acrylic had some flex in it, and with the lasers mounted to the acrylic... that flex caused issues with alignment and stuff. Also the projector was mounted right in front of the user... and any movement would jar the projector off its original location and cause vibration in the display. Lastly the mirror setup... while it was good for enabling a smaller frame footprint, it really caused issues with focus from the projector. I may revisit using mirrors later on... but I have redesigned the frame entirely.
I have also found that the primary use of this frame style is for DJing. Instead of building it for more of a universal user, I raised the rake of the screen so that it would be easier seen from the public side and raised the base height up a bit. The projector is now mounted at the bottom of the frame (and outwards by a short bit). Since it is just a pico projector and not a bright short throw, version 3 may end up being modified for a new projector... but that is down the road.
Lastly I made the frame design to be modular in order to transport it between events. It can be easily broken down using hands and a couple hand tools (note: 2 hex drivers) and ends up as 5 pieces. The wires are also ran inside the frame so that the frame is cleaner looking with also using spade connectors between the pieces. Its made from 1" square steel, so its not light... but extremely sturdy and rigid. I also have changed the projection surface to be sandwiched between a 1/2" thick piece of acrylic and an 1/4" piece of acrylic instead of superglueing it to the back of the acrylic. This helps with being able to replace it when necessary and also keeps it from being damaged in transport.
The laser mounts are hard mounted to the frame that also holds and supports the acrylic. I used some screw bars, cut them up and welded them to each of the corners for the brackets. Hopefully the design allows for a high level of accuracy when aligning them and a low amount of possible de-alignment through use.
In the coming days (weather permitted) I will be finished with paint (also making it more of a finished product) and wiring and will be able to take some pictures and video of it in action.
