Hi Guys !

I’m pretty silent on this forum( i read a lot ! )

I started A DSI project with Pocket projector (95mm X 80mm X 45mm).
Pretty cool to reduce the size(i want something pretty portable for my Live set,i’m musician)
this gave me a 17-19 inch display for only 30cm of height(i think i can reduce with multiple mirrors...)

Ok, here the problem:

I use an EndLighten Acrylic with Ir led ribbon, all it’s ok, but the blobs is more strong and fast(to appears)when my fingers is wet…
it’s pressure sensitive. ok. but :
I have to use Compliant surface?
I have read it ,it’s not obligatory…

Oh, and i haven’t Ir filter ( i test on totally dark room) ? any influence?

Thank you all for any helps.

Bye

ps: sorry for my bad english...i’m French and school is so far…

DSI works on the DI principal so theoretically a compliant surface isnt required. I read some where that Tim had to get the edges of the Acrylic really polished he got it professionally done so that may be the issue with you. Cause if you are getting brighter blobs when you wet your fingers that means you aren’t exploiting the properties of the acrylic, you are simply just making a regular FTIR screen.

Yes it’s maybee this…

I have polished it but it’s not like “glass” , but the structure of this acrylic is strange… like 3 layers( one clear clean, one braided , one clear and clean..)

Well i think i have to find some Super polishman professional...argh...more bucks on this…

My is also not like a glass. It’s milky. But only one layer.
