Working on the main body.  Still need battery holders, display, LED pcb... a lot yet.

Two standoffs are where the blower mounts, which puts it flush with the inside of the (missing) cover.  The blower shaft goes through the hole in the middle here extending up into the portal fluid container.

I was going to ask Daren, which LED's are you going with? 1W or >1W?

  Are you sure? yes | no

3 groups of LEDs, at 11w input power each, but I'm too cheap to buy COB LED elements... so....  

20-24 element array of scavenged Walmart bulb LEDs which output ~46 lumens per, so 24 would produce 1100 lumens.  That puts total light output hitting the image discs at 3300 lumens.  I imagine we will be able to project 1/3 to 2/3rds of that without collimation (as the fresnel lens collimator experiment was a failure).  If nothing else, it will be a good flashlight.
